Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular, to an air conditioner and a method for processing the ambient temperature of an air conditioner. Background Art

[0002] With the increasing improvement of people's living standards, air conditioners have become necessities in daily life and can achieve various functions such as refrigeration, heating, and dehumidification. The existing control strategies of air conditioners include collecting the indoor ambient temperature and determining whether the refrigeration or heating effect is achieved according to the difference between the indoor ambient temperature and the set temperature. When the refrigeration or heating effect is achieved, the air conditioner will stop for processing.

[0003] In order to collect the indoor ambient temperature, a temperature sensor is usually provided on the air conditioner housing. However, since the temperature sensor on the air conditioner housing is relatively close to the air outlet of the air conditioner, the collected ambient temperature information is quite different from the actual indoor ambient temperature, which easily leads to inaccurate operation control of the air conditioner. There is also a temperature sensor provided on the air conditioner remote control. The air conditioner remote control is placed indoors, and the collected ambient temperature information is relatively close to the actual ambient temperature. However, there are defects such as the air conditioner remote control being covered, blocked, or moved outdoors, resulting in inaccurate ambient information being collected or a large difference in the temperature information collected at different times, leading to abnormal temperature reaching and starting and stopping of the air conditioner. Therefore, how to obtain accurate and stable ambient temperature information is of great significance for the normal operation of the air conditioner. Summary of the Invention

[0004] The purpose of the embodiments of the present invention is to provide an air conditioner and a method for processing the ambient temperature of an air conditioner, which can accurately and stably collect the ambient temperature in the air-conditioned room, improve the accuracy of the operation control of the air conditioner, and improve the user experience.

[0005] To achieve the above purpose, the embodiments of the present invention provide an air conditioner, including:

[0006] An indoor unit;

[0007] A body temperature sensor, provided on the housing of the indoor unit, for collecting temperature information to obtain a first temperature;

[0008] A peripheral temperature sensor, for collecting temperature information to obtain a second temperature;

[0009] A controller, connected to the body temperature sensor and the peripheral temperature sensor, for:

[0010] After the air conditioner is powered on, if the second temperature is received, select the second temperature as the current ambient temperature;

[0011] During the operation of the air conditioner, if the first temperature and the second temperature are received simultaneously, the magnitudes of the first temperature and the second temperature are compared in real time;

[0012] When the difference between the first temperature and the second temperature is greater than the first temperature threshold, a temperature correction value is obtained as the current ambient temperature; wherein, the temperature correction value is calculated based on the first temperature.

[0013] As an improvement to the above solution, when the difference between the first temperature and the second temperature is greater than the first temperature threshold, obtaining a temperature correction value as the current ambient temperature is specifically:

[0014] When the difference between the first temperature and the second temperature is greater than the first temperature threshold and the first temperature is greater than the second temperature, the temperature correction value is calculated based on the difference between the first temperature and the first temperature threshold, and the temperature correction value is selected as the current ambient temperature;

[0015] When the difference between the first temperature and the second temperature is greater than the first temperature threshold and the first temperature is less than the second temperature, the temperature correction value is calculated based on the sum of the first temperature and the first temperature threshold, and the temperature correction value is selected as the current ambient temperature.

[0016] As an improvement to the above solution, after obtaining the temperature correction value as the current ambient temperature, the controller is further configured to:

[0017] When the difference between the first temperature and the second temperature is less than the second temperature threshold, the current ambient temperature is adjusted at a first preset temperature change rate until the current ambient temperature is equal to the second temperature;

[0018] Select the second temperature as the current ambient temperature, and execute the step: compare the magnitudes of the first temperature and the second temperature in real time.

[0019] As an improvement to the above solution, the controller is further configured to:

[0020] During the operation of the air conditioner, if it changes from receiving the first temperature and the second temperature simultaneously, or only receiving the second temperature, to only receiving the first temperature, the current ambient temperature is adjusted at a second preset temperature change rate until the current ambient temperature is equal to the first temperature;

[0021] Select the first temperature as the current ambient temperature.

[0022] As an improvement to the above solution, after selecting the first temperature as the current ambient temperature, the controller is further configured to:

[0023] When the second temperature is received again, adjust the current ambient temperature at a second preset temperature change rate until the current ambient temperature is equal to the second temperature;

[0024] Select the second temperature as the current ambient temperature, and perform the step of: comparing the magnitudes of the first temperature and the second temperature in real time.

[0025] As an improvement to the above solution, the controller is further configured to:

[0026] When the air conditioner is powered on or during operation, if the first temperature and the second temperature are not received, control the air conditioner to stop.

[0027] As an improvement to the above solution, the controller is further configured to:

[0028] After the air conditioner is powered on, if only the first temperature is received, select the first temperature as the current ambient temperature;

[0029] During the operation of the air conditioner, when the second temperature is received again, adjust the current ambient temperature at a second preset temperature change rate until the current ambient temperature is equal to the second temperature;

[0030] Select the second temperature as the current ambient temperature, and perform the step of: comparing the magnitudes of the first temperature and the second temperature in real time.

[0031] As an improvement to the above solution, the first temperature threshold is determined by the following method: According to the correspondence between the preset operation mode of the air conditioner and the first temperature threshold, obtain the first temperature threshold corresponding to the current operation mode of the air conditioner, and determine the current first temperature threshold.

[0032] As an improvement to the above solution, the second temperature threshold is determined by the following method: According to the correspondence between the preset operation mode of the air conditioner and the second temperature threshold, obtain the second temperature threshold corresponding to the current operation mode of the air conditioner, and determine the current second temperature threshold.

[0033] An embodiment of the present invention further provides a method for processing the ambient temperature of an air conditioner, where the air conditioner includes:

[0034] An indoor unit;

[0035] A body temperature sensor, disposed on the housing of the indoor unit, for collecting temperature information to obtain a first temperature;

[0036] A peripheral temperature sensor, for collecting temperature information to obtain a second temperature;

[0037] The method includes:

[0038] After the air conditioner is powered on, if the second temperature is received, select the second temperature as the current ambient temperature;

[0039] During the operation of the air conditioner, if the first temperature and the second temperature are received simultaneously, compare the magnitudes of the first temperature and the second temperature in real time;

[0040] When the difference between the first temperature and the second temperature is greater than the first temperature threshold, obtain the temperature correction value as the current ambient temperature; wherein, the temperature correction value is calculated based on the first temperature.

[0041] Compared with the prior art, for the air conditioner and the ambient temperature processing method of the air conditioner disclosed in the present invention, the air conditioner includes a body temperature sensor for collecting the first temperature, and also includes a peripheral temperature sensor for collecting the second temperature. After the air conditioner is powered on, if the second temperature is received, select the second temperature as the current ambient temperature; during the operation of the air conditioner, if the first temperature and the second temperature are received simultaneously, compare the magnitudes of the first temperature and the second temperature in real time; when the difference between the first temperature and the second temperature is greater than the first temperature threshold, obtain the temperature correction value as the current ambient temperature; wherein, the temperature correction value is calculated based on the first temperature. By adopting the technical means of the embodiments of the present invention, the air conditioner preferentially uses the second temperature collected by the peripheral temperature sensor as the current ambient temperature to execute the operation strategy of the air conditioner, thereby avoiding the situation that the temperature information collected by the body temperature sensor is too different from the actual indoor ambient temperature, resulting in inaccurate operation control of the air conditioner and easy temperature reaching and shutdown. Moreover, when the first temperature and the second temperature differ greatly, the temperature correction value is determined according to the first temperature to correct the current ambient temperature, which can also avoid the situation that inaccurate temperature information is collected by the peripheral temperature sensor in special cases, and using the second temperature as the current ambient temperature easily leads to inaccurate operation control of the air conditioner. At the same time, it also avoids directly switching the current ambient temperature to the first temperature, resulting in too large a difference in the ambient temperature values used by the air conditioner before and after, leading to abnormal temperature reaching and shutdown of the air conditioner. This enables the air conditioner room to obtain a relatively accurate and stable ambient temperature value, improves the accuracy of air conditioner operation control, and improves the user experience.

[0052] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0053] The embodiment of the present invention provides an air conditioner 10, which can be used to perform functions such as refrigeration, heating, and dehumidification.

[0054] In an alternative implementation manner, referring to Figure 1 , it is a schematic structural diagram of an air conditioner in the first preferred embodiment of the present invention. The air conditioner is a split air conditioner, including an indoor unit 20 and an outdoor unit 30. The indoor unit 20 includes a blowing device such as an air outlet. The outdoor unit 30 includes a functional system composed of devices such as a compressor, an evaporator, and a condenser. The specific structures and working principles of the indoor unit 20 and the outdoor unit 30 of the split air conditioner can refer to the prior art and will not be elaborated here.

[0055] In another embodiment, the air conditioner is an integrated air conditioner, including an indoor unit. The indoor unit integrates a function system composed of a air supply device such as an air outlet and a compressor, etc. The specific structure and working principle of the integrated air conditioner can refer to the prior art and will not be elaborated here.

[0056] The air conditioner 10 further includes a body temperature sensor 21 and a peripheral temperature sensor 40. The body temperature sensor 21 is disposed on the housing of the indoor unit 20. The body temperature sensor 21 can collect the temperature information of the current location as the first temperature T1.

[0057] The peripheral temperature sensor 40 is not disposed on the housing of the air conditioner. Optionally, referring to Figure 2 , which is a schematic structural diagram of the air conditioner in the second preferred embodiment of the present invention. The air conditioner 10 further includes a remote controller 50. The remote controller 50 is an independent device that can communicate with the air conditioner, receive the control instructions of the user for the air conditioner, and realize the operation control of the air conditioner. Then the peripheral temperature sensor 40 can be disposed in the remote controller 50. The peripheral temperature sensor can collect the temperature information of the current location as the second temperature T2.

[0058] Of course, the peripheral temperature sensor 40 can also be disposed in a device independent of the air conditioner, such as an indoor humidifier, an indoor thermometer, etc., which does not affect the beneficial effects of the present invention.

[0059] The air conditioner 10 further includes a controller. The controller can be disposed in the air conditioner 10 for realizing the operation control of the air conditioner 10. The controller is respectively connected and communicates with the body temperature sensor 21 and the peripheral temperature sensor 40, so as to receive the first temperature T1 sent by the body temperature sensor 21 and the second temperature T2 sent by the peripheral temperature sensor 40.

[0060] It should be noted that the communication between the controller and the body temperature sensor 21 and the peripheral temperature sensor 40 can adopt an infrared signal communication method, a Bluetooth communication method, a wifi communication method. Of course, other wired or wireless communication methods can also be adopted, which are not specifically limited here.

[0061] As an example, taking the air conditioner 10 including the remote controller 50 as an example, the remote controller 50 is provided with a peripheral temperature sensor 40. The remote controller 50 automatically sends an infrared signal at regular intervals (for example, every 1 minute) for transmitting the second temperature value to the controller.

[0062] Referring to Figure 3 , which is a schematic flowchart of the work executed by the controller in the first preferred embodiment of the present invention. The controller is used to execute steps S11 to S13:

[0063] After the air conditioner is powered on, if the second temperature is received, select the second temperature as the current ambient temperature;

[0064] During the operation of the air conditioner, if the first temperature and the second temperature are received simultaneously, compare the magnitudes of the first temperature and the second temperature in real time;

[0065] When the difference between the first temperature and the second temperature is greater than the first temperature threshold, obtain the temperature correction value as the current ambient temperature; wherein, the temperature correction value is calculated based on the first temperature.

[0066] In the embodiment of the present invention, when the air conditioner 10 is powered on, if the controller can receive the second temperature T2, including two cases: only receiving the second temperature T2 sent by the peripheral temperature sensor 40, and receiving the first temperature T1 sent by the body temperature sensor 21 and the second temperature T2 sent by the peripheral temperature sensor 40 simultaneously, both select the second temperature T2 as the current ambient temperature, substitute it into the self-owned operation strategy of the air conditioner, and realize the operation control of the air conditioner. Of course, the current ambient temperature will be updated in real time according to the second temperature collected by the peripheral temperature sensor 40 in real time.

[0067] During the operation of the air conditioner, if the air conditioner only receives the second temperature T2 sent by the peripheral temperature sensor 40, then always use the second temperature T2 as the current ambient temperature.

[0068] If the controller receives the first temperature T1 sent by the body temperature sensor 21 and the second temperature T2 sent by the peripheral temperature sensor 40 simultaneously, then compare the magnitudes of the first temperature T1 and the second temperature T2, and correct the value of the current ambient temperature according to the comparison result of the first temperature T1 and the second temperature T2.

[0069] Specifically, determine the first temperature threshold △T1. When the difference between the first temperature and the second temperature is greater than the first temperature threshold, that is, when |T1 - T2| > △T1 is satisfied, obtain the temperature correction value Tset as the current ambient temperature, and substitute it into the self-owned operation strategy of the air conditioner.

[0070] Preferably, in order to make the processing of the current ambient temperature more accurate and avoid frequent adjustment, set the first preset duration t1. Then step S13 is specifically: when the difference between the first temperature and the second temperature is greater than the first temperature threshold and lasts for the first preset duration, obtain the temperature correction value as the current ambient temperature.

[0071] It can be understood that the first preset duration t1 can be set according to the actual situation. For example, set t1 = 1 minute.

[0072] Understandably, after the air conditioner is powered on and operates with the second temperature as the current ambient temperature, if the difference between the first temperature and the second temperature always satisfies being less than or equal to the first temperature threshold, that is, satisfies |T1 - T2| ≤ ΔT1, then the received second temperature T2 is always used as the current ambient temperature.

[0073] By adopting the technical means of the embodiments of the present invention, the air conditioner preferentially uses the second temperature T2 collected by the peripheral temperature sensor as the current ambient temperature for executing the operation strategy of the air conditioner, thereby being able to avoid the situation that the temperature information collected by the body temperature sensor is too different from the actual indoor ambient temperature, resulting in inaccurate operation control of the air conditioner and easy reaching the set temperature and shutting down. Moreover, when the first temperature and the second temperature differ greatly, the temperature correction value is determined according to the first temperature to correct the current ambient temperature, which can also avoid the situation that due to the inaccurate temperature information collected by the peripheral temperature sensor under special circumstances, using the second temperature as the current ambient temperature is likely to lead to inaccurate operation control of the air conditioner. At the same time, it also avoids directly switching the current ambient temperature to the first temperature, which may cause the ambient temperature value adopted by the air conditioner to differ too much before and after, resulting in abnormal reaching the set temperature and shutting down of the air conditioner, enabling the air-conditioned room to obtain a relatively accurate and stable ambient temperature value, improving the accuracy of the operation control of the air conditioner and enhancing the user experience.

[0074] Preferably, the temperature correction value Tset is calculated according to the first temperature T1 and the first temperature threshold ΔT1.

[0075] Specifically, referring to Figure 4 , it is a schematic flowchart of the work executed by the controller in the second preferred embodiment in the embodiments of the present invention. Step S13, that is, when the difference between the first temperature and the second temperature is greater than the first temperature threshold, obtaining the temperature correction value as the current ambient temperature, specifically includes steps S131 and S132:

[0076] S131. When the difference between the first temperature and the second temperature is greater than the first temperature threshold and the first temperature is greater than the second temperature, calculate the temperature correction value according to the difference between the first temperature and the first temperature threshold, and select the temperature correction value as the current ambient temperature;

[0077] S132. When the difference between the first temperature and the second temperature is greater than the first temperature threshold and the first temperature is less than the second temperature, calculate the temperature correction value according to the sum of the first temperature and the first temperature threshold, and select the temperature correction value as the current ambient temperature.

[0078] That is, when |T1 - T2| > ΔT1 and T1 > T2 are satisfied, the temperature correction value Tset = T1 - ΔT1; when |T1 - T2| > ΔT1 and T1 < T2 are satisfied, the temperature correction value Tset = T1 + ΔT1, which is used as the current ambient temperature and substituted into the existing operation strategy of the air conditioner.

[0079] By adopting the technical means of the embodiment of the present invention, the temperature correction value Tset is calculated and determined based on the first temperature T1 and the first temperature threshold ΔT1. By directly switching the current ambient temperature to the temperature correction value, the ambient temperature value used in the existing operation strategy of the air conditioner will not fluctuate greatly, and abnormal temperature reaching and starting and stopping of the air conditioner can be avoided.

[0080] It should be noted that the first temperature threshold ΔT1 is a preset temperature value, which can be set according to actual application situations. Preferably, the first temperature threshold ΔT1 can be determined in the following manner: according to the corresponding relationship between the preset operation mode of the air conditioner and the first temperature threshold, obtain the first temperature threshold corresponding to the current operation mode of the air conditioner, and determine the current first temperature threshold.

[0081] That is, the first temperature thresholds corresponding to different operation modes of the air conditioner are preset, and a corresponding relationship table is established. During the operation of the air conditioner, according to the current operation mode of the air conditioner, determine the specific value of the first temperature threshold.

[0082] As an example, the air conditioner includes a cooling mode and a heating mode. Then, in the corresponding relationship between the preset operation mode of the air conditioner and the first temperature threshold, the first temperature threshold ΔT1 corresponding to the cooling mode is 4°C, and the first temperature threshold ΔT1 corresponding to the heating mode is 6°C.

[0083] That is, in the cooling mode, if |T1 - T2| > 4°C and T1 > T2, the temperature correction value Tset = T1 - 4°C, which is used as the current ambient temperature of the air conditioner; if |T1 - T2| > 4°C and T1 < T2, the temperature correction value Tset = T1 + 4°C, which is used as the current ambient temperature of the air conditioner.

[0084] In the heating mode, if |T1 - T2| > 6°C and T1 > T2, the temperature correction value Tset = T1 - 6°C, which is used as the current ambient temperature of the air conditioner; if |T1 - T2| > 6°C and T1 < T2, the temperature correction value Tset = T1 + 6°C, which is used as the current ambient temperature of the air conditioner.

[0085] Of course, the above scenarios are only for illustration. In actual applications, the specific values of the first temperature thresholds corresponding to the cooling and heating modes of the air conditioner can be set according to the actual situation, or other operating modes of the air conditioner and their corresponding first temperature thresholds can be set according to the actual situation, which will not be specifically limited here.

[0086] Preferably, after step S13, the controller is further configured to: push a preset prompt message to remind the user to perform an anomaly detection.

[0087] That is, when the difference between the first temperature T1 and the second temperature T2 is large and satisfies |T1 - T2| > ΔT1, it indicates that there is an anomaly in the body temperature sensor 21 and / or the peripheral temperature sensor 40. Therefore, by pushing the corresponding prompt message, the user is reminded to check whether the indoor unit return air filter is dirty or whether the position of the peripheral temperature sensor is reasonable, so that the difference between the first temperature T1 and the second temperature T2 returns to the normal range.

[0088] It can be understood that the module for displaying the prompt message can be set on the indoor unit housing, or on the remote controller, or on the mobile terminal of the user that establishes a communication connection with the air conditioner, which is convenient for the user to view the prompt message in a timely and intuitive manner.

[0089] As a preferred embodiment, refer to Figure 5 , which is a schematic flowchart of the work performed by the controller in the third preferred embodiment of the embodiments of the present invention. The embodiments of the present invention are further implemented on the basis of the above embodiments. After performing step S13, that is, after obtaining the temperature correction value as the current ambient temperature, the controller is further configured to perform step S14:

[0090] S14. When the difference between the first temperature and the second temperature is less than the second temperature threshold, adjust the current ambient temperature at a first preset temperature change rate until the current ambient temperature is equal to the second temperature; select the second temperature as the current ambient temperature, and perform the steps of: continuously comparing the magnitudes of the first temperature and the second temperature in real time.

[0091] In the embodiments of the present invention, a second temperature threshold ΔT2 is set. When |T1 - T2| > ΔT1, the temperature correction value Tset is obtained as the current ambient temperature. When the difference between the first temperature T1 and the second temperature T2 shrinks and the magnitude relationship satisfies |T1 - T2| < ΔT2, the air conditioner 10 still preferentially uses the second temperature T2 as the current ambient temperature and substitutes it into the self-owned operation strategy of the air conditioner for air conditioner operation control.

[0092] In order to avoid large fluctuations in the ambient temperature values used by the air conditioner when directly switching to the second temperature T2, in the embodiments of the present invention, when |T1 - T2| < ΔT2 is satisfied, the current ambient temperature is adjusted at the first preset temperature change rate r1 until the current ambient temperature is equal to the second temperature T2. After that, the second temperature T2 collected in real time is used as the current ambient temperature and substituted into the self-owned operation strategy of the air conditioner. Then, it jumps back to step S12 to compare the first temperature and the second temperature in real time and execute downward according to the judgment result.

[0093] As an example, r1 is set to 0.5 °C / min. That is, assuming the current ambient temperature is 23 °C and the second temperature T2 is 25 °C, the current ambient temperature is increased with a step size of 0.5 °C and an adjustment period of 1 minute until it reaches 25 °C. Of course, the first preset temperature change rate r1 can be set according to the actual situation and is not specifically limited here.

[0094] It should be noted that the second temperature threshold ΔT2 is a preset temperature value, which can be set according to the actual application situation. Preferably, the second temperature threshold ΔT2 can be determined in the following way: according to the corresponding relationship between the preset operation mode of the air conditioner and the second temperature threshold, obtain the second temperature threshold corresponding to the current operation mode of the air conditioner, and determine the current second temperature threshold.

[0095] That is, the first temperature thresholds corresponding to different operation modes of the air conditioner are preset in advance to establish a corresponding relationship table. During the operation of the air conditioner, the specific value of the first temperature threshold is determined according to the current operation mode of the air conditioner.

[0096] As an example, the air conditioner includes a cooling mode and a heating mode. Then, in the corresponding relationship between the preset operation mode of the air conditioner and the second temperature threshold, the second temperature threshold ΔT2 corresponding to the cooling mode is 3 °C, and the first temperature threshold ΔT1 corresponding to the heating mode is 5 °C.

[0097] That is, in the cooling mode, if |T1 - T2| < 3 °C, the current ambient temperature is adjusted at the first preset temperature change rate r1 until the current ambient temperature is equal to the second temperature T2, which is used as the current ambient temperature of the air conditioner; in the heating mode, if |T1 - T2| < 5 °C, the current ambient temperature is adjusted at the first preset temperature change rate r1 until the current ambient temperature is equal to the second temperature T2, which is used as the current ambient temperature of the air conditioner.

[0098] Of course, the above scenarios are only for illustration. In actual applications, the specific values of the second temperature thresholds corresponding to the cooling and heating modes of the air conditioner can be set according to the actual situation, or other operating modes of the air conditioner and their corresponding second temperature thresholds can be set according to the actual situation, which will not be specifically limited here.

[0099] As a preferred embodiment, refer to Figure 6 , which is a schematic flowchart of the work performed by the controller in the fourth preferred embodiment in the embodiments of the present invention. The embodiments of the present invention are further implemented on the basis of any of the above embodiments, and the controller is further configured to execute step S21:

[0100] S21. During the operation of the air conditioner, if the first temperature and the second temperature are received simultaneously, or only the second temperature is received, and then only the first temperature is received, adjust the current ambient temperature at a second preset temperature change rate until the current ambient temperature is equal to the first temperature; select the first temperature as the current ambient temperature.

[0101] The controller obtains the first temperature T1 collected by the body temperature sensor 21 and the second temperature T2 collected by the peripheral temperature sensor 40 in real time. However, there may be a situation where the peripheral temperature sensor 40 fails or is in an abnormal state, resulting in the inability to collect the second temperature T2, or the peripheral temperature sensor 40 is disconnected from the controller, resulting in the controller being unable to obtain the second temperature T2 collected by the peripheral temperature sensor 40. For example, taking the air conditioner 10 including the remote control 50 as an example, the peripheral temperature sensor 40 is provided on the remote control 50, and the remote control 50 sends an infrared signal automatically at regular intervals to transmit the second temperature value to the controller. When the remote control 50 is too far away from the air conditioner controller, or the remote control 50 is blocked or has insufficient power or other abnormal situations, the controller cannot receive the infrared signal of the remote control 50, resulting in the inability to receive the second temperature T2.

[0102] In the embodiments of the present invention, when the controller only receives the first temperature T1 collected by the body temperature sensor 21 and cannot receive the second temperature T2 collected by the peripheral temperature sensor 40, the air conditioner 10 switches to using the first temperature T1 as the current ambient temperature and substitutes it into the self-owned operation strategy of the air conditioner for air conditioner operation control.

[0103] In order to avoid the direct switch to the first temperature T1 causing too large fluctuations in the ambient temperature value adopted by the air conditioner, in the embodiments of the present invention, when the second temperature T2 cannot be received, the current ambient temperature is adjusted at a second preset temperature change rate r2 until the current ambient temperature is equal to the first temperature T1, and then the first temperature T1 collected in real time is used as the current ambient temperature and substituted into the self-owned operation strategy of the air conditioner.

[0104] For example, set r2 to 0.2 °C / min. That is, assume the current ambient temperature is 25 °C and the first temperature T1 is 23 °C. Then, with an adjustment step of 0.2 °C and an adjustment period of 1 minute, the current ambient temperature is reduced until it reaches 23 °C. Of course, the second preset temperature change rate r2 can be set according to actual situations and is not specifically limited herein.

[0105] Preferably, in order to make the processing of the current ambient temperature more accurate and avoid frequent adjustments, a second preset duration t2 is set. Then, step S21 is specifically as follows: During the operation of the air conditioner, when only the first temperature is received within the continuous second preset duration, the current ambient temperature is adjusted at the second preset temperature change rate until the current ambient temperature is equal to the first temperature; select the first temperature as the current ambient temperature.

[0106] It can be understood that the second preset duration t2 can be set according to actual situations. For example, set t2 = 12 minutes.

[0107] As a preferred embodiment, refer to Figure 7 , which is a schematic flowchart of the work executed by the controller in the fifth preferred embodiment in the embodiments of the present invention. The embodiments of the present invention are further implemented on the basis of the previous embodiment. After step S21, the controller is further configured to execute step S22:

[0108] S22. When the second temperature is received again, adjust the current ambient temperature at the second preset temperature change rate until the current ambient temperature is equal to the second temperature; select the second temperature as the current ambient temperature, and execute the step: Compare the magnitudes of the first temperature and the second temperature in real time.

[0109] In the embodiments of the present invention, after only the first temperature T1 is received and the first temperature T1 is selected as the current ambient temperature, if the controller receives the second temperature T2 collected by the peripheral temperature sensor 40 again, the air conditioner 10 still preferentially uses the second temperature T2 as the current ambient temperature. To avoid the ambient temperature value adopted by the air conditioner fluctuating too much due to a direct switch to the second temperature T2, the current ambient temperature is also adjusted at the second preset temperature change rate r2 until the current ambient temperature is equal to the second temperature T2. Then, the second temperature T2 collected in real time is used as the current ambient temperature and substituted into the self-owned operation strategy of the air conditioner. After that, step S12 is executed again to compare the first temperature and the second temperature, and according to the magnitude relationship between the two, the current ambient temperature is determined in the manner of the above embodiment.

[0110] As a preferred embodiment, the embodiments of the present invention are further implemented on the basis of any of the above embodiments. The controller is further configured to execute step S23:

[0111] S23. After the air conditioner is powered on or during operation, if the first temperature and the second temperature are not received, control the air conditioner to stop.

[0112] The controller obtains the first temperature T1 collected by the body temperature sensor 21 and the second temperature T2 collected by the peripheral temperature sensor 40 in real time. However, there may be a situation where neither the first temperature T1 collected by the body temperature sensor 21 nor the second temperature T2 collected by the peripheral temperature sensor 40 is received. For example, the body temperature sensor 21 fails or is in an abnormal state, resulting in the inability to collect the first temperature T1, or the body temperature sensor 21 is disconnected from the controller, causing the controller to be unable to obtain the first temperature T1 collected by the body temperature sensor 21; the peripheral temperature sensor 40 fails or is in an abnormal state, resulting in the inability to collect the second temperature T2, or the peripheral temperature sensor 40 is disconnected from the controller, causing the controller to be unable to obtain the second temperature T2 collected by the peripheral temperature sensor 40.

[0113] In the embodiment of the present invention, when the controller does not receive the first temperature and the second temperature at the same time, the air conditioner 10 is controlled to be in a stopped state. Optionally, the controller sends a corresponding prompt message to remind the user to check and repair the air conditioner.

[0114] As a preferred embodiment, refer to Figure 8 , which is a schematic flowchart of the work performed by the controller in the sixth preferred embodiment in the embodiment of the present invention. The embodiment of the present invention is further implemented on the basis of any of the above embodiments, and the controller is further configured to execute step S31:

[0115] S31. After the air conditioner is powered on, if only the first temperature is received, select the first temperature as the current ambient temperature.

[0116] Further, refer to Figure 9 , which is a schematic flowchart of the work performed by the controller in the seventh preferred embodiment in the embodiment of the present invention.

[0117] After step S31, the controller is further configured to execute steps S32 and S33:

[0118] S32. During the operation of the air conditioner, when the second temperature is received again, adjust the current ambient temperature at a second preset temperature change rate until the current ambient temperature is equal to the second temperature;

[0119] S33. Select the second temperature as the current ambient temperature, and execute the step: compare the magnitudes of the first temperature and the second temperature in real time.

[0120] In an embodiment of the present invention, when the air conditioner 10 is powered on, assuming that the peripheral temperature sensor 40 is in a faulty or abnormal state, or the peripheral temperature sensor 40 is disconnected from the controller, such that the controller only receives the first temperature T1 collected by the body temperature sensor 21 and cannot receive the second temperature T2 collected by the peripheral temperature sensor 40, then the first temperature T1 is selected as the current ambient temperature and brought into the self-owned operation strategy of the air conditioner to achieve the operation control of the air conditioner.

[0121] After that, during the operation of the air conditioner, if the peripheral temperature sensor 40 returns to normal, or the controller re-establishes a connection with the peripheral temperature sensor 40 and the controller can receive the second temperature T2 collected by the peripheral temperature sensor 40 again, the air conditioner 10 still preferentially uses the second temperature T2 as the current ambient temperature. In order to avoid the ambient temperature value used by the air conditioner fluctuating too much before and after directly switching to the second temperature T2, the current ambient temperature is also adjusted at the second preset temperature change rate r2 until the current ambient temperature is equal to the second temperature T2. After that, the second temperature T2 collected in real time is used as the current ambient temperature and brought into the self-owned operation strategy of the air conditioner. After that, step S12 is executed again to compare the magnitudes of the first temperature and the second temperature, and according to the magnitude relationship between the two, the current ambient temperature is determined in the manner of the above embodiment.

[0122] By adopting the technical means of the embodiment of the present invention, the air conditioner preferentially uses the second temperature collected by the peripheral temperature sensor as the current ambient temperature. If the second temperature cannot be received, the first temperature collected by the body temperature sensor is used as the current ambient temperature. Moreover, during the switching process between the two temperatures, it is gradually adjusted at a certain temperature change rate, effectively avoiding the temperature fluctuation caused by direct switching, enabling the air-conditioned room to obtain a relatively accurate and stable ambient temperature value, and improving the accuracy of the air conditioner operation control.

[0123] See Figure 10 FIG. is a schematic flowchart of a method for processing the ambient temperature of an air conditioner in an embodiment of the present invention. The embodiment of the present invention also provides a method for processing the ambient temperature of an air conditioner, and the air conditioner includes:

[0124] An indoor unit; a body temperature sensor disposed on the housing of the indoor unit for collecting temperature information to obtain a first temperature; a peripheral temperature sensor for collecting temperature information to obtain a second temperature;

[0125] The method for processing the ambient temperature includes steps S41 to S43:

[0126] S41. After the air conditioner is powered on, if the second temperature is received, the second temperature is selected as the current ambient temperature;

[0127] S42. During the operation of the air conditioner, if the first temperature and the second temperature are received simultaneously, compare the magnitudes of the first temperature and the second temperature in real time;

[0128] S43. When the difference between the first temperature and the second temperature is greater than the first temperature threshold, obtain a temperature correction value as the current ambient temperature; wherein, the temperature correction value is calculated based on the first temperature.

[0129] By adopting the technical means of the embodiments of the present invention, the air conditioner preferentially uses the second temperature T2 collected by the peripheral temperature sensor as the current ambient temperature to execute the operation strategy of the air conditioner, thereby avoiding the situation that the temperature information collected by the body temperature sensor is too different from the actual ambient temperature in the room, resulting in inaccurate operation control of the air conditioner and easy temperature reaching and shutdown. Moreover, when the first temperature and the second temperature differ greatly, a temperature correction value is determined according to the first temperature to correct the current ambient temperature, which can also avoid the situation that inaccurate temperature information is collected by the peripheral temperature sensor under special circumstances, and using the second temperature as the current ambient temperature easily leads to inaccurate operation control of the air conditioner. At the same time, it also avoids directly switching the current ambient temperature to the first temperature, resulting in too large a difference in the ambient temperature values used by the air conditioner before and after, leading to abnormal temperature reaching and shutdown of the air conditioner, enabling the air-conditioned room to obtain a relatively accurate and stable ambient temperature value, improving the accuracy of air conditioner operation control, and improving the user experience.

[0130] Preferably, after step S43, the method further includes step S44:

[0131] When the difference between the first temperature and the second temperature is less than the second temperature threshold, adjust the current ambient temperature at a first preset temperature change rate until the current ambient temperature is equal to the second temperature; select the second temperature as the current ambient temperature, and execute the step: compare the magnitudes of the first temperature and the second temperature in real time.

[0132] Preferably, the method further includes steps S45 and S46:

[0133] S45. During the operation of the air conditioner, if the situation changes from receiving the first temperature and the second temperature simultaneously, or only receiving the second temperature, to only receiving the first temperature, adjust the current ambient temperature at a second preset temperature change rate until the current ambient temperature is equal to the first temperature; select the first temperature as the current ambient temperature.

[0134] S46. When the second temperature is received again, adjust the current ambient temperature at a second preset temperature change rate until the current ambient temperature is equal to the second temperature; select the second temperature as the current ambient temperature, and perform the step of: comparing the magnitudes of the first temperature and the second temperature in real time.

[0135] It should be noted that an ambient temperature processing method provided in an embodiment of the present invention has the same all process steps as those executed by a controller of an air conditioner in the above embodiment, and the working principles and beneficial effects of the two correspond one by one, so details will not be repeated here.

[0137] The above is the preferred implementation manner of the present invention. It should be pointed out that for those of ordinary skill in the art in the technical field, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
