The environment temperature sensing bag is exposed to air and is used to detect the temperature of a room environment. The pipe temperature sensing bag is generally in contact with an indoor unit pipeline and is used to detect whether the pipeline temperature is abnormal. The environment temperature sensing bag is an important temperature detection device of the indoor unit. If the temperature sensing bag completely fails, the air conditioner cannot run. If the temperature sensing bag does not completely fail, it will affect the sampling accuracy of the air conditioner main control and the user experience.

[0035] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below in combination with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present application.

[0036] It is considered that, for the temperature sensing bag of an indoor unit of an air conditioner, if the temperature sensing bag is completely in failure, the air conditioner cannot run, and if the temperature sensing bag is not completely in failure, the sampling accuracy of the main control of the air conditioner will be affected, thereby affecting the user experience. Specifically, when the temperature sensing bag is in a completely in failure state due to a normal fault such as open circuit or short circuit, the main control of the air conditioner can timely and effectively report the fault to remind the user; but for some abnormal faults of the temperature sensing bag other than the completely in failure state, such as the resistance value of the temperature sensing bag becoming a constant value after long-time use, or the resistance value range changing too much, the main control of the air conditioner generally does not report the fault, but the temperature sampling is not accurate, which will affect the user experience.

[0037] Therefore, the present application provides a control method for an air conditioner, specifically an abnormality detection and control method for a temperature sensing bag of an indoor unit of an air conditioner, which compares the temperature collected by a remote controller with the temperature collected by the temperature sensing bag of the air conditioner, and can detect short circuit, open circuit or resistance value error of the temperature sensing bag, effectively determine whether the temperature sensing bag is abnormal, avoid the existence of non-completely in failure abnormality, affect the temperature sampling accuracy of the indoor unit, and improve the user experience.

[0038] According to the embodiments of the present application, a control method for an air conditioner is provided, as shown in Figure 1A flowchart of an embodiment of the method of the application is shown. The indoor unit of the air conditioner has an indoor environment temperature sensing package; in the scheme of the application, as shown in the figure Figure 1 The control method of the air conditioner includes steps S110 to S130.

[0039] At step S110, in the case where the air conditioner is running in the current mode, the indoor environment temperature detected by the indoor environment temperature sensing package is obtained, denoted as the first indoor temperature of the air conditioner, the first indoor temperature being, for example, T 环 ; and the indoor environment temperature detected by the temperature detection module in the environment where the indoor unit of the air conditioner is located is obtained, denoted as the second indoor temperature of the air conditioner, the temperature detection module being, for example, a module corresponding to the temperature detection function of the remote controller or other temperature detection components in the indoor, the second indoor temperature being, for example, T 遥 . The temperature detection module is different from the indoor environment temperature sensing package in detecting the indoor environment temperature; that is, the detection of the indoor environment temperature by the temperature detection module and the detection of the indoor environment temperature by the indoor environment temperature sensing package are separate detections.

[0040] At step S120, according to the first indoor temperature of the air conditioner or the second indoor temperature of the air conditioner, it is determined whether the air conditioner has run to the target temperature in the current mode.

[0041] At step S130, if it is determined that the air conditioner has run to the target temperature in the current mode, then in the current mode, according to the first indoor temperature of the air conditioner and the second indoor temperature of the air conditioner, it is determined whether the indoor environment temperature sensing package is faulty, and a prompt message is initiated if it is determined that the indoor environment temperature sensing package is faulty; of course, if it is determined that the air conditioner has not run to the target temperature in the current mode, then the air conditioner is controlled to maintain the current operation.

[0042] The abnormality detection scheme of the indoor unit temperature sensing package of the air conditioner proposed in the scheme of the application is an effective detection method for the abnormality of the indoor unit temperature sensing package of the air conditioner, and can effectively detect the abnormality of the temperature sensing package in some non-failure conditions, thereby improving the user experience of using the air conditioner.

[0043] In some embodiments, the temperature detection module includes the remote controller of the air conditioner, in particular, a temperature detection component of the remote controller of the air conditioner.

[0044] The first indoor temperature of the air conditioner includes the detection value of the indoor environment temperature sensing package sampled by the IO port of the main control chip of the air conditioner; and the second indoor temperature of the air conditioner includes the temperature detected by the remote controller of the air conditioner.

[0045] The specific process of determining whether the air conditioner runs to the target temperature in the current mode according to the first indoor temperature of the air conditioner or the second indoor temperature of the air conditioner in step S120 will be described below.

[0046] The specific process of determining whether the air conditioner runs to the target temperature in the current mode according to the first indoor temperature of the air conditioner or the second indoor temperature of the air conditioner in step S120 will be described below. Figure 2 An embodiment flowchart for determining whether the air conditioner runs to the target temperature in the current mode in the method of the air conditioner shown in

[0047] In step S210, it is determined whether the first indoor temperature of the air conditioner or the second indoor temperature of the air conditioner reaches the target temperature in the current mode.

[0048] In step S220, if it is determined that the first indoor temperature of the air conditioner or the second indoor temperature of the air conditioner reaches the target temperature in the current mode, it is determined that the air conditioner runs to the target temperature in the current mode; of course, if it is determined that neither the first indoor temperature of the air conditioner nor the second indoor temperature of the air conditioner reaches the target temperature in the current mode, it is determined that the air conditioner does not run to the target temperature in the current mode.

[0049] Figure 8 The structure of the control system of the indoor unit of the air conditioner is shown in the figure. The scheme of the present application proposes a fault detection scheme for the indoor temperature sensing bag, and the main control system is shown in Figure 8 The control system of the indoor unit of the air conditioner mainly includes an MCU main control system, a temperature detection circuit, a data processing module, a data receiving circuit, etc. The indoor unit of the air conditioner is connected to the MCU main control system, and the MCU main control system is connected to the temperature detection circuit, the data processing module and the data receiving circuit.

[0050] The MCU main control system mainly realizes the control function of the whole control system, and the temperature detection circuit is used for temperature detection sampling. The collected environmental temperature and the temperature data received by the remote controller are processed by the data processing module and sent to the MCU main control system. The threshold value is compared with the initial setting to determine whether the temperature sensing bag is abnormal. In this way, the non-failure state of the temperature sensing bag can be detected, and even when the temperature sensing bag has been used for a long time and the resistance value deviates, it can also be detected.

[0051] The data processing module can be a common sampling conversion circuit, such as a conversion circuit for converting the sampled analog signal into a digital signal, facilitating module differentiation and writing. In actual use, an MCU master control chip with more functions can replace and realize this function. The sampled level in the circuit can be 1V, 2V, etc., but the signal that the master control chip can process is only 0 and 1, so the sampling conversion circuit is needed to convert the collected level into 0 and 1 data combination, so that the MCU can process the signal. The ambient temperature data collected by the temperature sensing bag sensor is sent to the data processing module, and the temperature collected by the remote controller is also sent to the MCU master control system. The MCU master control system will also send the temperature collected by the remote controller to the data processing module. The data processing module is responsible for comparing the data size of the two and outputting an analog signal to the MCU master control system.

[0052] Figure 9 The structure diagram of the temperature sensing bag sampling circuit is shown in FIG. 1. Figure 9 As shown in FIG. 1, the temperature sensing bag sampling circuit includes a temperature sensing bag RT, a resistor R1, a resistor R2, and a capacitor C. The power supply VCC is connected to the IO port of the air conditioner master control through the temperature sensing bag RT and the resistor R1, the common end of the temperature sensing bag RT and the resistor R1 is connected to the ground through the resistor R2, and the common end of the resistor R1 and the IO port of the air conditioner master control is connected to the ground through the capacitor C.

[0053] Figure 9 The schematic diagram of the temperature sensing bag sampling circuit is shown in FIG. 1, wherein V CC represents the power supply, RT represents the temperature sensing bag material, R2 represents the voltage dividing resistor, and thus the level collected by the IO port of the air conditioner master control is V IO = (R2 / (RT+R2))*V CC R1 represents the current limiting resistor, and when the master control MUC has an integrated current limiting resistor, R1 can be cancelled. The resistance value of the temperature sensing bag RT can change with the temperature, for example, the resistance value of the temperature sensing bag RT is 5kΩ when the ambient temperature is 10℃, the resistance value is 10kΩ when the ambient temperature is 15℃, and the resistance value of the temperature sensing bag RT is 15kΩ when the ambient temperature is 20℃ (a temperature resistance value table corresponding to the temperature sensing bag drawing will be provided, and the above resistance values are only for convenience). The resistance value of the resistor R2 is a fixed value, which can be selected by the manufacturer (for example, 15kΩ), V CC = 5V (the power supply value can be selected by the manufacturer), and when the resistance value of the temperature sensing bag RT is 15kΩ, V IO = (R2 / (RT+R2))*V CC= 2.5V, that is, when the IO port of the air conditioner main control samples the voltage of 2.5V (the air conditioner main control will set the IO port to collect different voltages according to the resistance value table corresponding to different temperatures in the temperature sensing bag drawing, combined with the fixed value of the resistor R2 in the circuit, to represent different temperature values corresponding to different temperatures, for example, when the IO voltage is 3.1V, it is judged that the ambient temperature is 16℃; when the voltage is 2.5V, it is judged that the ambient temperature is 20℃, etc.), the main control judges that the indoor environment temperature is 20℃ at this time, if the user sets the target temperature to 20℃, at this time, it is considered that the outlet temperature reaches the set target value, and the compressor stops running. Because the resistance value of the temperature sensing bag material changes with the temperature, the resistance value of the temperature sensing bag RT is different at different ambient temperatures, so after voltage division with the resistor R2, the main control chip can detect different voltage values.

[0054] The abnormal detection scheme for the temperature sensing bag of the indoor unit of the air conditioner provided by the scheme can effectively judge whether the temperature sensing bag is abnormal, avoid the existence of non-complete failure, affect the temperature sampling accuracy of the indoor unit, and improve the user experience.

[0055] In some embodiments, the current mode includes a refrigeration or dehumidification mode.

[0056] In step S130, in the current mode, whether the indoor environment temperature sensing bag is faulty is determined according to the first indoor temperature of the air conditioner and the second indoor temperature of the air conditioner, and a prompt message is initiated in the case that the indoor environment temperature sensing bag is determined to be faulty, including: a process of determining whether the indoor environment temperature sensing bag is faulty in the refrigeration or dehumidification mode.

[0057] The specific process of determining whether the indoor environment temperature sensing bag is faulty in the refrigeration or dehumidification mode in the method of the air conditioner shown in FIG. 1 will be further described below. Figure 3 The specific process of determining whether the indoor environment temperature sensing bag is faulty in the refrigeration or dehumidification mode in step S130 will be further described below with reference to the embodiment flowchart of determining whether the indoor environment temperature sensing bag is faulty in the refrigeration or dehumidification mode in the method of the air conditioner shown in FIG. 1, including steps S310 to S340.

[0058] In step S310, in the refrigeration or dehumidification mode, whether the difference between the second indoor temperature of the air conditioner and the first indoor temperature of the air conditioner is greater than a first set temperature and less than a second set temperature is determined; wherein the first set temperature is temperature T1, and the second set temperature is temperature T2.

[0059] In step S320, in the refrigeration or dehumidification mode, if it is determined that the difference between the second indoor temperature of the air conditioner and the first indoor temperature of the air conditioner is greater than the first set temperature and less than the second set temperature, it is determined that the indoor environment temperature sensing bag is not faulty, and the air conditioner is controlled to continue the current operation.

[0060] Step S330, in the cooling or dehumidifying mode, if it is determined that the difference between the second indoor temperature of the air conditioner and the first indoor temperature of the air conditioner is greater than the first set temperature and less than the second set temperature, the target temperature in the current mode is adjusted downward by a first set value to obtain an adjusted target temperature in the cooling or dehumidifying mode; wherein the first set value is N degrees in the cooling or dehumidifying mode.

[0061] Step S340, in the cooling or dehumidifying mode, after the air conditioner is controlled to run for a first set time according to the adjusted target temperature in the cooling or dehumidifying mode, it is determined whether the indoor environment temperature sensing bag is faulty according to the current first indoor temperature of the air conditioner, and a prompt message is initiated in the case where it is determined that the indoor environment temperature sensing bag is faulty. Wherein the first set time is time t in the cooling or dehumidifying mode.

[0062] The scheme of the present application adopts the characteristic that the resistance value of the temperature sensing bag changes with the temperature, and divides the voltage through the temperature sensing bag RT and the resistor R2. When the resistance value of the temperature sensing bag RT changes, the voltage detected by the air conditioner main control IO port changes, indicating that different temperature points are collected, so it can be used for temperature detection function. In the conventional temperature sensing bag fault judgment, only the short circuit or open circuit of the temperature sensing bag can be detected. If the temperature sensing bag RT appears short circuit, the level detected by the air conditioner main control IO port is always high level, and the level is a constant value and does not change. When the temperature sensing bag appears open circuit, the level detected by the air conditioner main control IO port is always low level. The scheme of the present application compares the temperature collected by the remote controller with the problem collected by the air conditioner environment temperature sensing bag. When the air conditioner environment temperature sensing bag appears short circuit, open circuit or resistance value error, it can be detected, and the fault category detection range is more extensive.

[0063] In some embodiments, the specific process of controlling the air conditioner to run for a first set time according to the adjusted target temperature in the cooling or dehumidifying mode in step S340, determining whether the indoor environment temperature sensing bag is faulty according to the current first indoor temperature of the air conditioner, and initiating a prompt message in the case where it is determined that the indoor environment temperature sensing bag is faulty, see the following exemplary description.

[0064] The following will be described in detail with reference to the accompanying drawings. Figure 4 The following will be described in detail with reference to the accompanying drawings.

[0065] Step S410, in cooling or dehumidification mode, controlling the air conditioner to operate at a lower target temperature in cooling or dehumidification mode for a first set time, and obtaining the current first indoor temperature of the air conditioner; that is, controlling the air conditioner to operate at a lower target temperature in cooling or dehumidification mode for a first set time, and recording the first indoor temperature of the air conditioner as the current first indoor temperature of the air conditioner.

[0066] Step S420, in cooling or dehumidification mode, determine whether the current first indoor temperature of the air conditioner has changed; that is, determine whether the current first indoor temperature of the air conditioner has changed compared with the first indoor temperature of the air conditioner before the first set time; wherein, the current first indoor temperature of the air conditioner is such as the temperature corresponding to level V1, and the first indoor temperature of the air conditioner before the first set time is such as the temperature corresponding to level V2.

[0067] Step S430, in cooling or dehumidification mode, if it is determined that the current first indoor temperature of the air conditioner has changed, it is determined that the indoor environment temperature sensing package has a fault that is not completely failed, and a reminder message is sent that the indoor environment temperature sensing package is not completely failed but replacement is recommended.

[0068] Step S440, in cooling or dehumidification mode, if it is determined that the current first indoor temperature of the air conditioner has not changed, it is determined that the indoor environment temperature sensing package has completely failed, and a reminder message is sent that the indoor environment temperature sensing package has completely failed and needs to be replaced.

[0069] Figure 10 The figure is a flow chart of a method for detecting and controlling abnormalities of the temperature sensor package of an air conditioner indoor unit. Figure 10 In, T 遥 Indicates the ambient temperature collected by the remote control, T 环 Indicates the ambient temperature collected by the indoor unit temperature sensor. T1, T2, T3, and T4 are fixed constants set by the manufacturer. Figure 10 It represents the system judgment flow chart. Figure 10 As shown, the method for detecting and controlling abnormality of the temperature sensing package of the indoor unit of the air conditioner includes:

[0070] Step 1: When the air conditioner is running, determine whether the operating mode of the air conditioner is cooling or dehumidification mode: if so, execute step 2 to execute the process of abnormal detection and control of the indoor unit temperature sensor package in the cooling or dehumidification mode of the air conditioner; otherwise, execute step 3 to execute the process of abnormal detection and control of the indoor unit temperature sensor package in the heating mode of the air conditioner.

[0071] Step 2: In the cooling or dehumidification mode of the air conditioner (for example, the target temperature is set to 25°C), according to the ambient temperature T 环When the air conditioner runs to the target set temperature, the temperature T of the environment is collected by the temperature sensing package RT 环 The remote controller detects the temperature T of its surrounding environment 遥 and sends it to the air conditioner main control to determine whether the condition T1 < T 遥 -T 环 < T2 is met: if yes, step 21 is executed, i.e., the temperature sensing package is considered normal, otherwise, step 22 is executed to execute the flow of indoor unit temperature sensing package abnormality detection and control in the air conditioner's cooling or dehumidifying mode.

[0072] Step 21: when the condition T1 < T 遥 -T 环 < T2 is met (the condition values of T1 and T2 are set by the manufacturer), it is determined that the temperature sensing package is normal, and the temperature collected by the temperature sensing package and the temperature collected by the remote controller do not differ much.

[0073] Step 22: when the condition T1 < T 遥 -T 环 < T2 is not met, the level V1 of the air conditioner main control IO port at this time is recorded, and the target temperature value is simulated to be lowered by N °C (N value can be set by the manufacturer, for the convenience of illustration, it is assumed that N = 5, i.e., the simulated target temperature value is 20 °C) by the main control software. For example, the V1 level collected by the circuit IO is 2.5 V, and the temperature value corresponding to the 2.5 V voltage on the software is 25 °C. The simulated compensation temperature on the software makes the set target temperature become 20 °C, and the air conditioner re-runs according to the target temperature of 20 °C. After stabilization, the IO level value V2 in the circuit is collected again. The air conditioner runs according to the latest simulated target temperature value, and after a time t, the level V2 of the air conditioner main control IO port is recorded. If V1 = V2, it is considered that the resistance of the temperature sensing package has a fixed value failure, i.e., the resistance of the temperature sensing package becomes a fixed value and does not change with the temperature, and its temperature sampling function has completely failed, and a fault code is reported to remind the user. If V1 ≠ V2, it is considered that the resistance of the temperature sensing package has a relatively large error compared with the standard resistance table, and the temperature collected by the remote controller can be used in combination with the main control to continue to use by the software compensation method, and the user is reminded to contact the after-sales service for replacement.

[0074] Wherein, combined with the temperature collected by the remote controller, the main control continues to use through the software compensation mode, which can be through the first use of the software calibration mode, such as the first use of the factory, the level of the air conditioner main control IO port corresponding to each temperature value is consistent, for example, when the ambient temperature is 25℃, the level detected by the air conditioner main control IO port is 2.5V; With the increase of service life, the temperature sensing bag material has error, at this time, when the ambient temperature is 25℃, the level detected by the air conditioner main control IO port may be 2.3V, but 2.3V on the software may correspond to the ambient temperature of 23℃. Therefore, when it is detected that the temperature sensing bag has error, the software can process according to the first detected voltage as the calibration judgment value, and the temperature collected by the air conditioner at the first use of the factory and the corresponding voltage value as the initial value. There is a display panel on the air conditioner, which can display the fault code on the display panel to remind the user; or when the air conditioner has WIFI function, the abnormal data can be sent to the manufacturer through WIFI module.

[0075] In the refrigeration or dehumidification mode, the air conditioner works in the steady state, the remote controller sends the temperature value collected around to the air conditioner main control, the air conditioner main control compares the temperature data sent by the remote controller with the temperature sampled by the air conditioner main control self-temperature sensing bag RT, judges whether the indoor temperature sensing bag appears fault according to the preset difference range, and further judges the specific fault condition of the temperature sensing bag according to the software simulation output target temperature setting value, which can effectively judge whether the temperature sensing bag appears abnormal, avoid the existence of non-complete failure, affect the temperature sampling accuracy of indoor unit, and improve the user experience.

[0076] In some embodiments, the current mode includes a heating mode.

[0077] In step S130, whether the indoor environment temperature sensing bag is faulty is determined according to the first indoor temperature of the air conditioner and the second indoor temperature of the air conditioner in the current mode, and a prompt message is initiated in the case that it is determined that the indoor environment temperature sensing bag is faulty, and the process of determining whether the indoor environment temperature sensing bag is faulty in the heating mode is further included.

[0078] The specific process of determining whether the indoor environment temperature sensing bag is faulty in the heating mode in step S130 will be further described below with reference to the embodiment flowchart of the method of the application shown in the accompanying drawings. Figure 5 The specific process of determining whether the indoor environment temperature sensing bag is faulty in the heating mode in step S130 will be further described below with reference to the embodiment flowchart of the method of the application shown in the accompanying drawings.

[0079] In step S510, whether the difference between the first indoor temperature of the air conditioner and the second indoor temperature of the air conditioner is greater than the third set temperature and less than the fourth set temperature is determined in the heating mode; wherein the third set temperature is, for example, temperature T1, and the fourth set temperature is, for example, temperature T2.

[0080] Step S520, in the heating mode, if it is determined that the difference between the first indoor temperature of the air conditioner and the second indoor temperature of the air conditioner is greater than the third set temperature and less than the fourth set temperature, it is determined that the indoor environment temperature sensing package is not faulty, and the air conditioner is controlled to continue the current operation.

[0081] Step S530, in the heating mode, if it is determined that the difference between the first indoor temperature of the air conditioner and the second indoor temperature of the air conditioner is greater than the third set temperature and less than the fourth set temperature, the target temperature in the current mode is increased by the second set value to obtain the increased target temperature in the heating mode; wherein the second set value is such as N°C in the heating mode.

[0082] Step S540: In heating mode, the air conditioner is controlled to operate at the increased target temperature in heating mode for a second set time, and then, based on the current first indoor temperature of the air conditioner, whether the indoor temperature sensor package is faulty is determined. If the indoor temperature sensor package is faulty, a reminder message is issued. The second set time is, for example, time t in heating mode.

[0083] The solution of the present invention compares the temperature collected by the temperature sampling circuit of the remote control with the temperature collected by the indoor unit's temperature sensing package, and compares the obtained temperature difference with the preset threshold of the main control. If the obtained temperature difference differs too much from the preset threshold, it is considered that there is an abnormality in the temperature sensing package, the air conditioner reports a fault and reminds the user to contact after-sales personnel for repair and replacement.

[0084] Some solutions propose exhaust temperature sensor detection methods, such as fully opening the expansion valve and monitoring whether the exhaust temperature sensor changes to determine whether the temperature sensor is faulty; or controlling the expansion valve opening to determine whether the temperature sensor changes with the expansion valve opening. These two methods can only detect two failure states of the exhaust temperature sensor: short circuit or open circuit. If the temperature sensor fails in either of these two states, the collected temperature will remain the same regardless of the expansion valve opening. The solution of the present invention can not only detect short circuit or open circuit of the ambient temperature sensor, but also detect and determine the error offset of the temperature sensor resistance.

[0085] In some embodiments, after controlling the air conditioner to operate at the increased target temperature in the heating mode for the second set time in step S540, determining whether the indoor environment temperature sensing package is faulty based on the current first indoor temperature of the air conditioner, and initiating a reminder message when it is determined that the indoor environment temperature sensing package is faulty, refer to the following exemplary description for the specific process.

[0086] The following combination Figure 6An embodiment flowchart of the method of the application shown in the step S540 of determining whether the indoor environment temperature sensing package is faulty according to the current first indoor temperature of the air conditioner in the heating mode, further illustrates the specific process of determining whether the indoor environment temperature sensing package is faulty according to the current first indoor temperature of the air conditioner in the heating mode in the step S540, comprising the steps S610 to S640.

[0087] The step S610, in the heating mode, the air conditioner is controlled to run at the up-regulated target temperature in the heating mode for a second set time, and then the current first indoor temperature of the air conditioner is obtained; that is, after the air conditioner is controlled to run at the up-regulated target temperature in the heating mode for a second set time, the first indoor temperature of the air conditioner is recorded as the current first indoor temperature of the air conditioner;

[0088] The step S620, in the heating mode, it is determined whether the current first indoor temperature of the air conditioner changes; that is, it is determined whether the current first indoor temperature of the air conditioner changes compared with the first indoor temperature of the air conditioner before the second set time; wherein the current first indoor temperature of the air conditioner is the temperature corresponding to the level V1, and the first indoor temperature of the air conditioner before the second set time is the temperature corresponding to the level V2.

[0089] The step S630, in the heating mode, if it is determined that the current first indoor temperature of the air conditioner changes, it is determined that the indoor environment temperature sensing package appears a failure of not completely failing, and a prompt message that the indoor environment temperature sensing package does not completely fail but is suggested to be replaced is initiated;

[0090] The step S640, in the heating mode, if it is determined that the current first indoor temperature of the air conditioner does not change, it is determined that the indoor environment temperature sensing package appears a failure of completely failing, and a prompt message that the indoor environment temperature sensing package completely fails and needs to be replaced is initiated.

[0091] As shown in the figure, Figure 10 The air conditioner indoor unit temperature sensing package abnormality detection and control method further comprises:

[0092] Step 3, when the air conditioner is in the heating mode, when the air conditioner runs to reach the target set temperature, the temperature sensing package RT collects the environment temperature T 环 , the remote controller detects the ambient environment temperature T 遥 , and judges whether the condition T3 环 -T 遥 <T4 is met: if yes, step 31 is executed, that is, the temperature sensing package is considered normal, otherwise, step 32 is executed to execute the flow of the indoor unit temperature sensing package abnormality detection and control in the heating mode of the air conditioner.

[0093] Step 31, when the condition T3 环 -T遥 When the temperature is less than T4, the temperature sensor is judged to be normal.

[0094] Step 32: If T3 < T 环 -T 遥 When the temperature is less than T4, the voltage level V3 of the air conditioner main control IO port is recorded, and the software simulates raising the target temperature value by N°C. After time t, the voltage level V4 of the air conditioner main control IO port is recorded. If V3=V4, it is considered that the fixed value of the temperature sensing package resistance has failed, and a fault code is reported to remind the user; if V3≠V4, it is considered that the error of the temperature sensing package resistance relative to the standard resistance table is too large. The main control can continue to use it through software compensation based on the temperature collected by the remote control, and remind the user to contact after-sales for replacement.

[0095] Theoretically, T1 and T2 can range from [0, 5]. However, these values ​​are not fixed. Temperature thresholds vary between manufacturers and should be set based on actual conditions. For example, T1 ≥ 0 and T2 ≤ 10 are acceptable. The same applies to T3 and T4. Time t has no fixed value; it generally represents the time it takes for the air conditioner to reach steady state. It is recommended to be greater than 3 or 5 minutes.

[0096] In heating mode, when the air conditioner is working in a steady state, the remote control sends the ambient temperature value collected to the air conditioner main control. After receiving the temperature data sent by the remote control, the air conditioner main control compares it with the temperature sampled by the air conditioner main control's self-sensing package RT and judges whether the indoor temperature sensor package is faulty based on the preset difference range; and further judges the specific fault condition of the temperature sensor package based on the software simulation output target temperature value. It can effectively judge whether the temperature sensor package is abnormal, avoid the existence of non-complete failure anomalies, affect the accuracy of indoor unit temperature sampling, and improve user experience.

[0097] By adopting the technical solution of this embodiment, the indoor environment temperature sensing package (indoor environment temperature sensing package) of the air conditioner is used. After the air conditioner runs to the target temperature in cooling or dehumidification mode or in heating mode, it is judged whether the indoor environment temperature sensing package is faulty based on the detection value of the indoor environment temperature sensing package and the detection value of the indoor remote control, so as to issue a reminder message in case of a fault; thereby, by using the detection value of the indoor environment temperature sensing package and the detection value of the indoor remote control, it is possible to effectively judge whether the indoor environment temperature sensing package has an abnormality, avoid the existence of abnormalities that are not complete failures, affect the accuracy of indoor unit temperature sampling, and improve user experience.

[0098] According to an embodiment of the present invention, a control device for an air conditioner corresponding to the control method for an air conditioner is also provided. Figure 7 The structure diagram of an embodiment of the device of the present invention is shown in FIG. The indoor unit of the air conditioner has an indoor environment temperature sensor; in the solution of the present invention, Figure 7As shown, the control device of the air conditioner comprises an acquisition unit 102 and a control unit 104.

[0099] The acquisition unit 102 is configured to acquire an indoor environment temperature detected by the indoor environment temperature sensing package in a case where the air conditioner is running in a current mode, denoted as a first indoor temperature of the air conditioner, such as T 环 , and acquire an indoor environment temperature detected by a temperature detection module in an environment where the indoor unit of the air conditioner is located, denoted as a second indoor temperature of the air conditioner, such as T 遥 . The specific functions and processes of the acquisition unit 102 are described in step S110.

[0100] The control unit 104 is configured to determine whether the air conditioner runs to a target temperature in the current mode according to the first indoor temperature of the air conditioner or the second indoor temperature of the air conditioner. The specific functions and processes of the control unit 104 are described in step S120.

[0101] The control unit 104 is further configured to determine whether the indoor environment temperature sensing package fails according to the first indoor temperature of the air conditioner and the second indoor temperature of the air conditioner in the current mode if it is determined that the air conditioner runs to the target temperature in the current mode, and initiate a prompt message in a case where it is determined that the indoor environment temperature sensing package fails. Of course, if it is determined that the air conditioner does not run to the target temperature in the current mode, the air conditioner is controlled to maintain the current running. The specific functions and processes of the control unit 104 are further described in step S130.

[0102] The air conditioner indoor unit temperature sensing package abnormality detection scheme provided by the scheme is an effective detection method for the abnormality of the air conditioner indoor unit temperature sensing package. The abnormality of the temperature sensing package in a non-failure condition is effectively detected, and the use experience of the air conditioner is improved.

[0103] In some embodiments, the temperature detection module comprises a remote controller of the air conditioner, in particular a temperature detection component of the remote controller of the air conditioner.

[0104] The first indoor temperature of the air conditioner comprises a detection value of the indoor environment temperature sensing package sampled by an IO port of a main control chip of the air conditioner, and the second indoor temperature of the air conditioner comprises a temperature detected by a remote controller of the air conditioner.

[0105] The control unit 104 determines whether the air conditioner runs to the target temperature in the current mode according to the first indoor temperature of the air conditioner or the second indoor temperature of the air conditioner, comprising:

[0106] The control unit 104 is specifically further configured to determine whether the first indoor temperature of the air conditioner or the second indoor temperature of the air conditioner reaches the target temperature in the current mode. The specific functions and processes of the control unit 104 are also referred to step S210.

[0107] The control unit 104 is specifically further configured to determine that the air conditioner runs to the target temperature in the current mode if it is determined that the first indoor temperature of the air conditioner or the second indoor temperature of the air conditioner reaches the target temperature in the current mode. Of course, if it is determined that neither the first indoor temperature of the air conditioner nor the second indoor temperature of the air conditioner reaches the target temperature in the current mode, it is determined that the air conditioner does not run to the target temperature in the current mode. The specific functions and processes of the control unit 104 are also referred to step S220.

[0108] Figure 8 The structure diagram of the control system of the indoor unit of the air conditioner. The scheme of the present application proposes an indoor temperature sensing bag fault detection scheme, and the main control system is as shown in Figure 8 The control system of the indoor unit of the air conditioner mainly comprises an MCU main control system, a temperature detection circuit, a data processing module, a data receiving circuit, etc. The indoor unit of the air conditioner is connected with the MCU main control system, and the MCU main control system is connected with the temperature detection circuit, the data processing module and the data receiving circuit respectively.

[0109] Among them, the MCU main control system mainly realizes the control function of the whole control system, and the temperature detection circuit is used for temperature detection sampling. The collected environmental temperature and the temperature data received by the remote controller are processed by the data processing module and sent to the MCU main control system. The threshold value is compared to determine whether the temperature sensing bag is abnormal. In this way, the non-failure state of the temperature sensing bag can be detected, and even when the temperature sensing bag resistance deviates after long use, it can also be detected.

[0110] Among them, the data processing module can be a common sampling conversion circuit, such as a conversion circuit for converting the sampled analog signal into a digital signal, which is convenient for module distinction and writing. In actual use, a MCU control chip with more functions can replace this function. The environmental temperature data collected by the temperature sensing bag sensor is sent to the data processing module, and the temperature collected by the remote controller is also sent to the MCU main control system. The MCU main control system will also send the temperature collected by the remote controller to the data processing module. The data processing module is responsible for comparing the data size of the two and outputting an analog signal to the MCU main control system.

[0111] Figure 9 This is a schematic diagram of the structure of the temperature sensing package sampling circuit. Figure 9 As shown in FIG, the temperature sensing package sampling circuit includes: a temperature sensing package RT, a resistor R1, a resistor R2, and a capacitor C. Among them, the power supply VCC is connected to the IO port of the air conditioner main control through the temperature sensing package RT and the resistor R1, the common end of the temperature sensing package RT and the resistor R1 is grounded through the resistor R2, and the common end of the resistor R1 and the IO port of the air conditioner main control is grounded through the capacitor C.

[0112] Figure 9 Schematic diagram of the temperature sensing package sampling circuit, where V CC Indicates power supply, RT indicates temperature sensing package material, R2 indicates voltage divider resistor, so the level collected by the IO port of the air conditioner main control is V IO =(R2 / (RT+R2))*V CC The resistance of the temperature-sensing package RT can change with temperature. For example, when the ambient temperature is 10℃, the resistance of the temperature-sensing package RT is 5kΩ, when the ambient temperature is 15℃, it is 10kΩ, and when the ambient temperature is 20℃, the resistance of the temperature-sensing package RT is 15kΩ (the temperature-sensing package drawing will provide the corresponding temperature resistance table, the above resistance values ​​are just for example). The resistance of resistor R2 is a fixed value, which can be selected by the manufacturer (for example, 15kΩ). V CC =5V (power supply value can be selected by the manufacturer), when the resistance of the temperature sensor RT is 15kΩ, V IO =(R2 / (RT+R2))*V CC =2.5V. That is, when the air conditioner master's IO port samples a voltage of 2.5V (the air conditioner master will set the IO port to sample different voltages corresponding to different temperature values ​​based on the resistance table corresponding to different temperatures in the temperature sensor package drawing, combined with the fixed value of resistor R2 in the circuit. For example, when the IO voltage is 3.1V, the ambient temperature is judged to be 16°C; when the voltage is 2.5V, the ambient temperature is judged to be 20°C, etc.), the master determines that the indoor ambient temperature is 20°C. If the user sets the target temperature to 20°C, the air outlet temperature is considered to have reached the set target value, and the compressor will stop running. Because the resistance of the temperature sensor material itself changes with temperature, the resistance of the temperature sensor RT varies at different ambient temperatures. Therefore, after voltage division with resistor R2, the master chip can detect different voltage values.

[0113] The present invention proposes a scheme for detecting abnormalities in the temperature sensing package of an air conditioner indoor unit, which can effectively determine whether the temperature sensing package has abnormalities, avoid the occurrence of abnormalities that are not complete failures, affect the accuracy of indoor unit temperature sampling, and improve user experience.

[0114] In some embodiments, the current mode includes cooling or dehumidification mode.

[0115] The control unit 104 determines whether the indoor environment temperature sensing package is faulty according to the first indoor temperature of the air conditioner and the second indoor temperature of the air conditioner in the current mode, and initiates a prompt message in the case of determining that the indoor environment temperature sensing package is faulty, including: determining whether the indoor environment temperature sensing package is faulty in the cooling or dehumidifying mode, specifically as follows:

[0116] The control unit 104 is specifically further configured to determine whether the difference between the second indoor temperature of the air conditioner and the first indoor temperature of the air conditioner is greater than a first set temperature and less than a second set temperature in the cooling or dehumidifying mode. The first set temperature is, for example, temperature T1, and the second set temperature is, for example, temperature T2. The specific functions and processes of the control unit 104 are also referred to in step S310.

[0117] The control unit 104 is specifically further configured to determine that the indoor environment temperature sensing package is not faulty and control the air conditioner to continue the current operation if it is determined that the difference between the second indoor temperature of the air conditioner and the first indoor temperature of the air conditioner is greater than the first set temperature and less than the second set temperature in the cooling or dehumidifying mode. The specific functions and processes of the control unit 104 are also referred to in step S320.

[0118] The control unit 104 is specifically further configured to down-regulate the target temperature in the current mode by a first set value to obtain a down-regulated target temperature in the cooling or dehumidifying mode if it is determined that the difference between the second indoor temperature of the air conditioner and the first indoor temperature of the air conditioner is not greater than the first set temperature and not less than the second set temperature in the cooling or dehumidifying mode. The first set value is, for example, N degrees C in the cooling or dehumidifying mode. The specific functions and processes of the control unit 104 are also referred to in step S330.

[0119] The control unit 104 is specifically further configured to control the air conditioner to operate according to the down-regulated target temperature in the cooling or dehumidifying mode for a first set time, and then determine whether the indoor environment temperature sensing package is faulty according to the current first indoor temperature of the air conditioner and initiate a prompt message in the case of determining that the indoor environment temperature sensing package is faulty. The first set time is, for example, time t in the cooling or dehumidifying mode. The specific functions and processes of the control unit 104 are also referred to in step S340.

[0120] The scheme of the present application adopts the characteristic that the resistance value of the temperature sensing bag changes with the change of temperature, and divides the voltage through the temperature sensing bag RT and the resistance R2, when the resistance value of the temperature sensing bag RT changes, the voltage detected by the air conditioner main control IO port changes, indicating that different temperature points are collected, so it can be used for temperature detection function; in the conventional temperature sensing bag fault judgment, only the short circuit or open circuit of the temperature sensing bag can be detected, if the temperature sensing bag RT appears short circuit, the level detected by the air conditioner main control IO port is always high level, and the level is a constant value and does not change; when the temperature sensing bag appears open circuit, the level detected by the air conditioner main control IO port is always low level; the scheme of the present application compares the temperature collected by the remote controller and the problem collected by the air conditioner environment temperature sensing bag, when the air conditioner environment temperature sensing bag appears short circuit, open circuit or resistance value error, it can be detected, and the fault category detection range is more extensive.

[0121] In some embodiments, the control unit 104 controls the air conditioner to run at the lower target temperature in the cooling or dehumidifying mode for a first set time, and then determines whether the indoor environment temperature sensing bag is faulty according to the current first indoor temperature of the air conditioner, and initiates a reminder message if it is determined that the indoor environment temperature sensing bag is faulty, including:

[0122] The control unit 104 is specifically further configured to, in the cooling or dehumidifying mode, obtain the current first indoor temperature of the air conditioner after controlling the air conditioner to run at the lower target temperature in the cooling or dehumidifying mode for a first set time; that is, after controlling the air conditioner to run at the lower target temperature in the cooling or dehumidifying mode for a first set time, the first indoor temperature of the air conditioner is recorded as the current first indoor temperature of the air conditioner. The specific functions and processes of the control unit 104 are also referred to step S410.

[0123] The control unit 104 is specifically further configured to, in the cooling or dehumidifying mode, determine whether the current first indoor temperature of the air conditioner changes; that is, determine whether the current first indoor temperature of the air conditioner changes compared with the first indoor temperature of the air conditioner before the first set time; wherein the current first indoor temperature of the air conditioner is the temperature corresponding to the level V1, and the first indoor temperature of the air conditioner before the first set time is the temperature corresponding to the level V2. The specific functions and processes of the control unit 104 are also referred to step S420.

[0124] The control unit 104 is specifically further configured to, in the cooling or dehumidifying mode, if it is determined that the current first indoor temperature of the air conditioner changes, determine that the indoor environment temperature sensing bag has a failure that is not completely invalid, and initiate a reminder message that the indoor environment temperature sensing bag is not completely faulty but is recommended to be replaced. The specific functions and processes of the control unit 104 are also referred to step S430.

[0125] The control unit 104 is specifically configured to determine that the indoor environment temperature sensing bulb has a complete failure fault and initiate a prompt message that the indoor environment temperature sensing bulb has a complete failure and needs to be replaced, if it is determined that the first indoor temperature of the air conditioner does not change in the cooling or dehumidifying mode. The specific functions and processes of the control unit 104 are also described in step S440.

[0126] Figure 10 FIG. 1 is a flowchart of an air conditioner indoor unit temperature sensing bulb abnormality detection and control method. Figure 10 遥 T represents the ambient temperature collected by the remote controller, T 环 represents the ambient temperature collected by the indoor unit temperature sensing bulb, and T1, T2, T3 and T4 are constant values set by the manufacturer. Figure 10 FIG. 2 is a system judgment flowchart. As shown in FIG. 2, the air conditioner indoor unit temperature sensing bulb abnormality detection and control method comprises the following steps. Figure 10

[0127] Step 1: In the case of air conditioner operation, it is determined whether the operation mode of the air conditioner is a cooling or dehumidifying mode. If yes, step 2 is performed to execute the flow of the indoor unit temperature sensing bulb abnormality detection and control in the cooling or dehumidifying mode of the air conditioner. If not, step 3 is performed to execute the flow of the indoor unit temperature sensing bulb abnormality detection and control in the heating mode of the air conditioner.

[0128] Step 2: In the cooling or dehumidifying mode of the air conditioner (for example, the target temperature value is set to 25°C), when the air conditioner operates to reach the target set temperature, the temperature sensing bulb RT collects the ambient temperature T 环 , the remote controller detects the ambient temperature T 遥 of the remote controller and sends it to the air conditioner main control, and it is determined whether the condition T1 遥 -T 环 <T2 is met. If yes, step 21 is performed, that is, it is considered that the temperature sensing bulb is normal. If not, step 22 is performed to execute the flow of the indoor unit temperature sensing bulb abnormality detection and control in the cooling or dehumidifying mode of the air conditioner.

[0129] Step 21: When the condition T1 遥 -T 环 <T2 is met (wherein the condition values of T1 and T2 are set by the manufacturer), it is determined that the temperature sensing bulb is normal, and the temperature collected by the temperature sensing bulb and the temperature collected by the remote controller are not much different.

[0130] Step 22: When the condition T1 遥 -T 环 ​​When the T2 condition is met, record the level V1 of the air conditioner main control IO port at this time, and lower the target temperature value by N degrees C (N value can be set by the manufacturer, for the convenience of illustration, assume N = 5, that is, the simulated target temperature value is 20 degrees C) through the main control software simulation, and the air conditioner operates according to the latest simulated target temperature value. After a period of time t, record the level V2 of the air conditioner main control IO port. If V1 = V2, it is considered that the resistance of the temperature sensing bag has a fixed value failure, that is, the resistance of the temperature sensing bag does not change with the temperature, and its temperature sampling function has completely failed, and a fault code is reported to remind the user. If V1 ≠ V2, it is considered that the resistance of the temperature sensing bag has a relatively large error compared with the standard resistance table, and the temperature collected by the remote controller can be used for compensation by the main control through software, and the user is reminded to contact the after-sales service for replacement.

[0131] In combination with the temperature collected by the remote controller, the main control continues to use through software compensation, which can be realized by first using software calibration, such as the first use after factory shipment. The level of the air conditioner main control IO port corresponding to each temperature value is consistent, for example, when the ambient temperature is 25 degrees C, the level detected by the air conditioner main control IO port is 2.5V. With the increase of service life, the temperature sensing bag material has an error. At this time, when the ambient temperature is 25 degrees C, the level detected by the air conditioner main control IO port may be 2.3V, but 2.3V on the software may correspond to an ambient temperature of 23 degrees C. Therefore, when the error of the temperature sensing bag is detected, the software can use the first detected voltage as the calibration judgment value. The air conditioner has a display panel, which can display the fault code on the display panel to remind the user, or when the air conditioner has WIFI function, the WIFI module can send the abnormal data to the manufacturer.

[0132] In the refrigeration or dehumidification mode, the remote controller sends the temperature value collected around to the air conditioner main control, and the air conditioner main control compares the temperature data sent by the remote controller with the temperature sampled by the air conditioner main control self-temperature sensing bag RT to judge whether the indoor temperature sensing bag has a fault according to the preset difference range. According to the software simulated output target temperature value, the specific fault condition of the temperature sensing bag is further judged, which can effectively judge whether the temperature sensing bag has an abnormality, avoid the existence of non-complete failure, affect the temperature sampling accuracy of the indoor unit, and improve the user experience.

[0133] In some embodiments, the current mode includes a heating mode.

[0134] The control unit 104 determines whether the indoor environment temperature sensing bag is faulty according to the first indoor temperature of the air conditioner and the second indoor temperature of the air conditioner in the current mode, and initiates a reminder message when it is determined that the indoor environment temperature sensing bag is faulty, and further comprises: in the process of determining whether the indoor environment temperature sensing bag is faulty in the heating mode, specifically as follows:

[0135] The control unit 104 is further configured to determine, in heating mode, whether a difference between the first indoor temperature of the air conditioner and the second indoor temperature of the air conditioner is greater than a third set temperature and less than a fourth set temperature; the third set temperature may be, for example, temperature T1, and the fourth set temperature may be, for example, temperature T2. The specific functions and processing of the control unit 104 are further described in step S510.

[0136] The control unit 104 is further configured to, in heating mode, determine that the indoor temperature sensor is not faulty and control the air conditioner to continue current operation if it is determined that the difference between the first indoor temperature of the air conditioner and the second indoor temperature of the air conditioner is greater than a third set temperature and less than a fourth set temperature. The specific functions and processing of the control unit 104 are further described in step S520.

[0137] The control unit 104 is further configured to, in the heating mode, if it is determined that the difference between the first indoor temperature of the air conditioner and the second indoor temperature of the air conditioner is greater than the third set temperature and less than the fourth set temperature, increase the target temperature in the current mode by a second set value to obtain an increased target temperature in the heating mode; the second set value may be N°C in the heating mode. The specific functions and processing of the control unit 104 are further described in step S530.

[0138] The control unit 104 is further configured to, in heating mode, control the air conditioner to operate at the increased target temperature in heating mode for a second set time, then determine whether the indoor temperature sensor package is faulty based on the current first indoor temperature of the air conditioner, and initiate a reminder message if the indoor temperature sensor package is faulty. The second set time may be, for example, time t in heating mode. The specific functions and processing of the control unit 104 are further described in step S540.

[0139] The solution of the present invention compares the temperature collected by the temperature sampling circuit of the remote control with the temperature collected by the indoor unit's temperature sensing package, and compares the obtained temperature difference with the preset threshold of the main control. If the obtained temperature difference differs too much from the preset threshold, it is considered that there is an abnormality in the temperature sensing package, the air conditioner reports a fault and reminds the user to contact after-sales personnel for repair and replacement.

[0140] Some schemes propose exhaust temperature sensing bag detection methods, such as through a fully open expansion valve, by monitoring whether the exhaust temperature sensing bag changes to determine whether the temperature sensing bag fails; or by controlling different expansion valve openings, monitoring whether the temperature sensing bag changes with different expansion valve openings to determine whether the temperature sensing bag fails. These two methods can only detect whether the exhaust temperature sensing bag is short-circuited or open-circuited. If the temperature sensing bag fails in any way, the temperature collected by the temperature sensing bag will be the same regardless of the expansion valve opening. The scheme of the present application can not only detect whether the temperature sensing bag is short-circuited or open-circuited, but also detect whether the temperature sensing bag is faulty.

[0141] In some embodiments, the control unit 104 controls the air conditioner to run at the up-regulated target temperature in the heating mode for a second set time, and then determines whether the indoor environment temperature sensing bag is faulty based on the current first indoor temperature of the air conditioner, and initiates a reminder message if it is determined that the indoor environment temperature sensing bag is faulty, including:

[0142] The control unit 104 is specifically configured to, in the heating mode, obtain the current first indoor temperature of the air conditioner after controlling the air conditioner to run at the up-regulated target temperature in the heating mode for a second set time; that is, after controlling the air conditioner to run at the up-regulated target temperature in the heating mode for a second set time, record the first indoor temperature of the air conditioner as the current first indoor temperature of the air conditioner. The specific functions and processes of the control unit 104 are also described in step S610.

[0143] The control unit 104 is specifically configured to, in the heating mode, determine whether the current first indoor temperature of the air conditioner changes; that is, determine whether the current first indoor temperature of the air conditioner changes compared with the first indoor temperature of the air conditioner before the second set time; wherein the current first indoor temperature of the air conditioner is the temperature corresponding to the level V1, and the first indoor temperature of the air conditioner before the second set time is the temperature corresponding to the level V2. The specific functions and processes of the control unit 104 are also described in step S620.

[0144] The control unit 104 is specifically configured to, in the heating mode, if it is determined that the current first indoor temperature of the air conditioner changes, determine that the indoor environment temperature sensing bag has a failure that is not completely failed, and initiate a reminder message that the indoor environment temperature sensing bag is not completely failed but is recommended to be replaced. The specific functions and processes of the control unit 104 are also described in step S630.

[0145] The control unit 104 is further configured to determine that the indoor environment temperature sensing bulb has a complete failure in the heating mode if it is determined that the first indoor temperature of the air conditioner does not change, and initiate a prompt message that the indoor environment temperature sensing bulb has a complete failure and needs to be replaced. The specific functions and processes of the control unit 104 are also described in step S640.

[0146] As shown in Figure 10 , the air conditioner indoor unit temperature sensing bulb abnormality detection and control method further comprises:

[0147] Step 3, when the air conditioner is in the heating mode, when the air conditioner runs to the target set temperature, the temperature sensing bulb RT collects the ambient temperature T 环 , the remote controller detects the ambient temperature T 遥 , and judges whether the condition T3 < T 环 -T 遥 < T4 is met: if yes, step 31 is executed, that is, the temperature sensing bulb is considered normal, otherwise, step 32 is executed to execute the flow of the indoor unit temperature sensing bulb abnormality detection and control in the heating mode of the air conditioner.

[0148] Step 31, when the condition T3 < T 环 -T 遥 < T4 is met, it is judged that the temperature sensing bulb is normal.

[0149] Step 32, when the condition T3 < T 环 -T 遥 < T4 is not met, the level V3 of the air conditioner main control IO port is recorded, the target temperature value N ℃ is simulated to be increased, after a time t, the level V4 of the air conditioner main control IO port is recorded, if V3 = V4, it is considered that the resistance of the temperature sensing bulb has a fixed value failure, a fault code is reported to remind the user; if V3 ≠ V4, it is considered that the resistance of the temperature sensing bulb has a relatively large error compared with the standard resistance table, the temperature collected by the remote controller can be combined, the main control can continue to be used by software compensation, and the user is reminded to contact the after-sales service for replacement.

[0150] Wherein, the reasonable value range of T1 and T2 in theory can be [0, 5], but the value is not a fixed value, the temperature determination values of various manufacturers are different, and need to be set according to the actual situation, such as T1 ≥ 0 and T2 ≤ 10; the values of T3 and T4 are the same. The value of time t has no accurate fixed value, which is generally the time interval of the air conditioner running to the steady state, which is recommended to be greater than 3 or 5 minutes or more.

[0151] In the heating mode, when the air conditioner works in the steady state, the remote controller sends the collected temperature value to the air conditioner host, and the air conditioner host compares the temperature data sent by the remote controller with the temperature sampled by the self-temperature sensing bag RT of the air conditioner host, judges whether the indoor temperature sensing bag is faulty according to the preset difference range, and further judges the specific fault condition of the temperature sensing bag according to the software simulation output target temperature setting value, so as to effectively judge whether the temperature sensing bag is abnormal, avoid the abnormal existence of non-complete failure, affect the temperature sampling accuracy of the indoor unit, and improve the user experience.
