[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0051] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0052] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only embodiments of a part of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work should fall within the scope of protection of the present application.

[0053] The present invention provides a method for detecting indoor temperature. Figure 1 , Figure 1 This is a flow chart of a first embodiment of a method for detecting indoor temperature according to the present invention. The method comprises the following steps:

[0054] Step S10, determining whether the temperature sensor of the wire controller is abnormal;

[0055] The wire controller is used to collect relevant parameters during the operation of the unit, such as indoor temperature, humidity, etc.; the indoor parameters collected by the wire controller are given to the unit so that the unit can perform temperature control based on the indoor parameters.

[0056] The temperature sensor is used to detect the indoor temperature. The specific type and model of the temperature sensor can be set based on actual needs.

[0057] When the temperature sensor is abnormal, the control device in the wire controller, such as the wire controller body, will not be able to communicate with the temperature sensor. Therefore, whether the temperature sensor is abnormal can be determined by the communication status with the temperature sensor. Other methods can also be used to determine whether the temperature sensor is abnormal. For example, if there is an obvious error in the indoor temperature detected by the temperature sensor, the specific error judgment method can be set based on the characteristics of the temperature sensor.

[0058] When the temperature sensor is abnormal, a fault indication is given to remind the user that the temperature sensor is faulty and needs to be replaced; the fault indication may be provided by displaying the fault information on the display screen of the online controller or sending the fault information to the corresponding user terminal.

[0059] Step S20, if the temperature sensor of the wired controller is abnormal, obtaining the return air temperature of the indoor unit associated with the wired controller;

[0060] If the temperature sensor of the wire controller is normal, the temperature value monitored by the temperature sensor is used as the indoor temperature.

[0061] When the temperature sensor of the wire controller is abnormal, the wire controller cannot directly monitor the indoor temperature. Therefore, in order to ensure the normal operation of the unit, it is necessary to determine the indoor temperature by other means. In this embodiment, the indoor temperature is determined by the indoor unit return air temperature of the indoor unit associated with the wire controller.

[0062] The return air temperature of the indoor unit is the temperature of the return air outlet of the indoor unit. The indoor unit is provided with a temperature sensing device such as a temperature sensing package at the return air outlet to detect the return air temperature of the indoor unit.

[0063] The wire controller body establishes a communication connection with the control device of the indoor unit to obtain the return air temperature of the indoor unit.

[0064] Step S30, obtaining temperature-related data, wherein the temperature-related data is obtained from the historically recorded corresponding historical indoor unit return air temperature and historical indoor temperature;

[0065] Step S40: determining the indoor temperature corresponding to the indoor unit return air temperature through the temperature association data.

[0066] In the same space, the operating condition of the air conditioner has roughly the same effect on regulating the indoor temperature; therefore, there is a correlation between the indoor unit return air temperature and the indoor temperature, and the indoor unit return air temperature indicates the operating condition of the air conditioner. Therefore, after determining the temperature correlation data, the indoor temperature corresponding to the indoor return air temperature can be obtained based on the temperature correlation data.

[0067] The historical indoor unit return air temperature is the indoor unit return air temperature previously obtained by the wire controller; the historical indoor unit return air temperature can be obtained periodically, or when the power is turned on, turned off, or the indoor unit return air temperature changes.

[0068] The historical indoor temperature is the indoor temperature previously detected by the wire controller through the temperature sensor.

[0069] The historical indoor unit return air temperature and the historical indoor temperature both have a certain collection time, and there is a correlation between the historical indoor unit return air temperature and the historical indoor temperature at the same collection time. Therefore, temperature correlation data can be obtained based on the correspondence of the collection time.

[0070] It should be noted that the specific temperatures at different locations in the same space may be different. For example, when the air conditioner is turned on, the temperature near the indoor unit air outlet will be higher or lower based on the air conditioner operating mode. For example, in cooling mode, the temperature at the indoor unit air outlet is lower, while the temperature away from the indoor unit air outlet is higher. Therefore, the indoor temperature described in this embodiment and subsequent embodiments refers to the temperature at the location of the temperature sensor of the wire controller. It can be understood that the unit realizes temperature control based on the indoor temperature at the location of the temperature sensor. When the temperature sensor is abnormal, in order to ensure the uniformity of the unit control, the indoor temperature determined based on the indoor unit return air temperature also indicates the temperature at the location of the temperature sensor.

[0071] When the temperature sensor of the online controller of this embodiment is abnormal, the indoor temperature can be determined by the indoor unit return air temperature. At the same time, based on the temperature correlation data obtained from the historical records, the corresponding historical indoor unit return air temperature and the historical indoor temperature, the correlation between the indoor unit return air temperature and the indoor temperature can be accurately determined. Therefore, the indoor temperature can be accurately determined by the indoor unit return air temperature.

[0072] Further, follow-up Figure 2 In the second embodiment of the indoor temperature detection method of the present invention proposed based on the first embodiment of the present invention, the step S30 includes the following steps:

[0073] Step S31, determining the current operation mode of the indoor unit;

[0074] Step S32, matching the temperature-related data corresponding to the current operating mode, wherein the temperature-related data under different operating modes are obtained by the corresponding historical indoor unit return air temperature and the historical indoor temperature recorded under the corresponding operating mode.

[0075] The current operation mode is the real-time operation mode of the air conditioner; the operation modes include cooling mode, heating mode, and shutdown.

[0076] Under different operating modes, there are differences in the temperature control effect in the space, which leads to different correlations between the indoor unit return air temperature and the indoor temperature; therefore, in order to adapt to different operating modes, in this embodiment, corresponding temperature correlation data are set for different operating modes, that is, temperature correlation data is independently set for the cooling mode, temperature correlation data is independently set for the heating mode, and temperature correlation data is independently set for the shutdown mode; at the same time, the temperature correlation data corresponding to different modes are obtained based on the historical indoor unit return air temperature and the historical indoor temperature obtained in the mode; for example, the historical indoor unit return air temperature and the historical indoor temperature obtained in the cooling mode are used to generate the temperature correlation data corresponding to the cooling mode.

[0077] When it is necessary to obtain temperature-related data, the temperature-related data in the corresponding operating mode is obtained based on the current operating mode.

[0078] Furthermore, more temperature-related data can be set to match more specific application scenarios; such as generating corresponding temperature-related data based on outdoor ambient temperature + operating mode; such as the historical indoor unit return air temperature obtained when the outdoor environment is 30°C and the operating mode is cooling mode and the historical indoor temperature are used to generate temperature-related data corresponding to the outdoor environment of 30°C and cooling mode; when the outdoor environment is 30°C and the operating mode is cooling mode, when temperature-related data needs to be obtained, the temperature-related data of the outdoor environment and cooling mode is obtained; it can be understood that the temperature-related data set for more specific scene types can improve the accuracy of the correlation between the indoor unit return air temperature and the indoor temperature in more specific application scenarios, but the higher the requirement for the amount of preliminary data collection, the number of temperature-related data and the specific scene type can be set based on actual needs; the references for specific considerations of the scene type can also include humidity, wind speed, and air outlet direction.

[0079] This embodiment sets corresponding temperature correlation data according to a specific operation mode, so that the temperature correlation data can match different application scenarios, thereby improving the accuracy of the correlation between the return air temperature of the indoor unit and the indoor temperature.

[0080] Further, in a third embodiment of the indoor temperature detection method of the present invention proposed based on the first embodiment of the present invention, step S40 includes the following steps:

[0081] Step S41, determining whether the number of return air temperatures of the indoor unit is multiple;

[0082] Step S42, if there are multiple return air temperatures of the indoor units, then calculating the average return air temperature of the multiple return air temperatures of the indoor units;

[0083] Step S43: determining the indoor temperature corresponding to the average return air temperature through the temperature association data.

[0084] Based on the indoor temperature requirement, the number of indoor units set in the space may be one or more; when the number of indoor units is one, the temperature association data is obtained based on the historical indoor unit return air temperature corresponding to the indoor unit, and the corresponding indoor temperature can be determined based on the temperature association data and the indoor unit return air temperature corresponding to the indoor unit; and when the number of indoor units is multiple, in order to facilitate calculation and improve accuracy, the temperature association data is obtained based on the historical indoor unit return air temperature corresponding to each indoor unit, and the corresponding indoor temperature can be determined based on the temperature association data and the average return air temperature corresponding to the indoor unit. The average return air temperature is the average value of the indoor unit return air temperatures corresponding to each indoor unit.

[0085] Furthermore, when calculating the average return air temperature, a weighted average calculation method can be used; the distance between the air outlet of each indoor unit and the temperature sensor is obtained in advance. The closer the distance is, the greater the impact on the temperature at the location of the temperature sensor. Therefore, the closer the distance is, the higher the corresponding weight of the indoor unit.

[0086] In other embodiments, temperature association data may be jointly constructed based on the historical indoor unit return air temperatures of each indoor unit, and then the indoor temperatures corresponding to the return air temperatures of each indoor unit may be determined based on the temperature association data.

[0087] Furthermore, in a fourth embodiment of the indoor temperature detection method of the present invention proposed based on the first embodiment of the present invention, the method further includes the steps of:

[0088] Step S50, obtaining the historical indoor temperature and the historical indoor unit return air temperature detected by the temperature sensor;

[0089] Step S60, fitting the historical indoor temperature and the historical indoor unit return air temperature to obtain a temperature relationship curve;

[0090] Step S70: using the temperature relationship curve as the temperature association data.

[0091] In this embodiment, the correlation between the indoor unit return air temperature and the indoor temperature is characterized by fitting the temperature relationship curve; the fitting method of the temperature relationship curve can be set based on actual needs, such as the least square method; specifically, the indoor unit return air temperature is taken as the independent variable x, the indoor temperature detected by the temperature sensor of the wire controller is taken as the dependent variable y, and the indoor temperature and the indoor unit return air temperature satisfy the temperature relationship curve y=ax+b; the coefficients a and b are calculated by the historical indoor unit return air temperature and the historical indoor temperature; wherein:

[0092]

[0093]

[0094] Where n is the number of data; x i is the return air temperature of the i-th indoor unit, y i is the i-th indoor temperature.

[0095] After the coefficients a and b are determined, the other one can be determined based on the indoor unit return air temperature and the indoor temperature; for example, the temperature relationship curve in heating mode is y=0.997x-1.842; the temperature relationship curve in cooling mode is y=1.017x-1.273; the temperature relationship curve under shutdown is y=1.034x-0.98.

[0096] In this embodiment, the correlation between the return air temperature of the indoor unit and the indoor temperature can be clearly represented by setting the temperature relationship curve.

[0097] Furthermore, in a fifth embodiment of the indoor temperature detection method of the present invention proposed based on the first embodiment of the present invention, the method further includes the steps of:

[0098] Step S80, obtaining the real-time indoor temperature and the real-time indoor unit return air temperature detected by the temperature sensor at every preset collection time interval;

[0099] Step S90, determining the current operation mode of the indoor unit, and matching the temperature associated data corresponding to the current operation mode;

[0100] Step S100: updating the temperature associated data using the real-time indoor temperature and the real-time indoor unit return air temperature.

[0101] The preset collection time is used to indicate the period for obtaining new data; the specific value of the preset collection time can be set based on actual needs, such as 10 minutes.

[0102] When the temperature sensor of the online controller operates normally, the real-time indoor temperature and the real-time indoor unit return air temperature are obtained at every preset collection time interval; and the coefficients a and b are recalculated based on the newly obtained real-time indoor temperature and real-time indoor unit return air temperature and the previously obtained historical indoor temperature and historical indoor unit return air temperature to update the temperature relationship curve.

[0103] When the temperature sensor of the online controller is abnormal, the temperature-related data is no longer updated because the actual detected real-time indoor temperature cannot be directly obtained.

[0104] It can be understood that the real-time data collected in a specific application scenario is used to update the corresponding temperature-related data in the application scenario; for example, the real-time indoor temperature and real-time indoor unit return air temperature collected in the cooling mode are used to update the temperature-related data corresponding to the cooling mode.

[0105] In this embodiment, the temperature-related data is updated through the real-time data obtained periodically, so that the accuracy of the temperature-related data can be improved.

[0106] Further, in a sixth embodiment of the indoor temperature detection method of the present invention proposed based on the first embodiment of the present invention, step S20 includes the following steps:

[0107] Step S21, if the temperature sensor of the wired controller is abnormal, obtaining the return air operation state of the return air temperature sensor of the indoor unit associated with the wired controller;

[0108] Step S22, determining whether the return air operation state is abnormal;

[0109] Step S23, if the return air operation state is abnormal, an alarm operation is performed;

[0110] Step S24: If the return air operation state is normal, the return air temperature of the indoor unit detected by the return air temperature sensor is obtained.

[0111] If the return air operation state is abnormal, an alarm operation is performed.

[0112] The return air operation status indicates the effectiveness of the indoor unit return air temperature detection; when the return air outlet temperature sensor of the indoor unit fails or the communication between the wire controller and the indoor unit is disconnected, the wire controller cannot obtain the accurate return air temperature of the indoor unit. At this time, the indoor temperature cannot be determined by the return air temperature of the indoor unit. Therefore, in this case, an alarm operation is performed to remind the user to replace the temperature sensor in time and check for related abnormal problems.

[0113] When the return air operation status is normal, the wire controller can obtain the accurate return air temperature of the indoor unit and determine the indoor temperature based on the return air temperature of the indoor unit.

[0114] Specifically, after the wire controller is powered on, if it detects that the temperature sensor is abnormal, the status is maintained and the air conditioner is waiting to be turned on; after the air conditioner is turned on, if the return air operation status is normal, a temperature sensor abnormality reminder is issued, and after the user chooses to ignore it, the indoor temperature is determined by the return air temperature of the indoor unit; if the return air operation status is abnormal, the abnormal reminder is maintained, and the indoor temperature is not determined by the return air temperature of the indoor unit.

[0115] In this embodiment, it is possible to ensure that the indoor temperature is determined when the return air temperature of the indoor unit is obtained.

[0116] It should be noted that, for the aforementioned method embodiments, for the sake of simplicity, they are all expressed as a series of action combinations, but those skilled in the art should be aware that the present application is not limited by the described order of actions, because according to the present application, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by the present application.

[0117] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in each embodiment of the present application.

[0122] The second determination module is used to determine the indoor temperature corresponding to the return air temperature of the indoor unit through the temperature association data.

[0123] When the temperature sensor of the online controller is abnormal, the indoor temperature detection device can determine the indoor temperature through the indoor unit return air temperature. At the same time, based on the temperature correlation data obtained from the historical records, the corresponding historical indoor unit return air temperature and the historical indoor temperature, the correlation between the indoor unit return air temperature and the indoor temperature can be accurately determined. Therefore, the indoor temperature can be accurately determined through the indoor unit return air temperature.

[0124] It should be noted that the first determination module in this embodiment can be used to execute step S10 in the embodiment of the present application, the first acquisition module in this embodiment can be used to execute step S20 in the embodiment of the present application, the second acquisition module in this embodiment can be used to execute step S30 in the embodiment of the present application, and the second determination module in this embodiment can be used to execute step S40 in the embodiment of the present application.

After receiving the indoor temperature, the wire controller mainboard 12 sends the indoor temperature to the unit so that the unit performs temperature control based on the indoor temperature.

[0148] The wire controller body 1 and the temperature sensor component 2 are detachably arranged, so the temperature sensor component 2 can be disassembled alone to achieve replacement of the temperature sensor component 2 .

[0149] The wire controller main board 12 is also connected to the control device of the indoor unit for communication; the wire controller main board 12 can obtain relevant parameters of the indoor unit, such as the return air temperature of the indoor unit; when the temperature sensor 22 of the wire controller is abnormal, the wire controller cannot directly monitor the indoor temperature. Therefore, in order to ensure the normal operation of the unit, it is necessary to determine the indoor temperature by other means; in this embodiment, the indoor temperature is determined by the indoor unit return air temperature of the indoor unit associated with the wire controller.

[0150] Specifically, the wired controller body 1 is used to execute the aforementioned indoor temperature detection method, wherein the return air temperature of the indoor unit is obtained by the wired controller body 1 from the control device in the indoor unit.

[0151] In this embodiment, the wire controller body 1 and the temperature sensor component 2 are detachably arranged so that when the temperature sensor 22 fails, the temperature sensor component 2 can be replaced alone without replacing the entire wire controller, thereby reducing device waste; at the same time, the wire controller main board 12 is also communicated with the indoor unit control device, so that the indoor temperature can be determined based on the relevant parameters of the indoor unit control device.

[0152] Furthermore, the wire controller body 1 and the temperature sensor component 2 are connected by a press buckle.

[0153] The press buckle usually consists of two parts: one is a fixed part and the other is a movable part. The fixed part is usually a fixed seat or hook, while the movable part is a movable buckle or latch; the movable part and the fixed part are respectively set on the wire controller body 1 and the temperature sensor component 2, the movable part is inserted into the fixed part, and then the movable part is pressed to lock it with the fixed part; when disassembly is required, just press the movable part and pull it outward to separate the wire controller body 1 and the temperature sensor component 2.

[0154] It should be noted that the pressing buckle is a feasible detachable setting method. In practical applications, other structures can also be provided to achieve the detachability between the wire controller body 1 and the temperature sensor component 2.

[0155] Further, see Figure 3 as well as Figure 4 The wire controller body 1 includes a wire controller housing 11, a wire controller mainboard 12 and a plurality of elastic ejector pins 13; wherein:

[0156] The wire controller mainboard 12 is disposed in the wire controller housing 11, and the elastic ejector pins 13 are disposed in openings provided on the wire controller housing 11; the wiring terminals 121 of the wire controller mainboard 12 are connected to the corresponding elastic ejector pins 13 one by one through wires;

[0157] The temperature sensor component 2 includes a sensor housing 21, the temperature sensor 22 and a plurality of copper sheets 23; wherein:

[0158] The temperature sensor 22 is disposed in the sensor housing 21, and the copper sheet 23 is disposed on the sensor housing 21; the connection terminals of the temperature sensor 22 are connected to the copper sheet 23 in a one-to-one correspondence through wires;

[0159] When the wire controller body 1 is connected to the temperature sensor component 2 , the elastic ejector pins 13 are connected to the copper sheets 23 in a one-to-one correspondence.

[0160] The wire controller housing 11 is used to protect its internal components; the wire controller mainboard 12 is used to implement data processing functions; it can be understood that the wire controller mainboard 12 includes specific components such as a microprocessor, related circuits, and memory to implement data processing; the specific structure of the wire controller body 1 can be set based on actual needs and is not limited here.

[0161] The sensor housing 21 is used to protect its internal components; the temperature sensor 22 is used to detect the indoor temperature; the specific type, model, and structure of the temperature sensor 22 can be set based on actual needs and are not limited here.

[0162] The elastic ejector pin 13 contacts the copper sheet 23 to realize the communication connection between the wire controller main board 12 and the temperature sensor 22; when the wire controller main body 1 is connected to the temperature sensor component 2, the elastic ejector pin 13 contacts the copper sheet 23. At this time, the wiring terminal 121 of the wire controller main board 12 is connected to the wiring terminal of the temperature sensor 22 through the wire, the elastic ejector pin 13, the copper sheet 23, and the wire in sequence, thereby realizing the connection between the wire controller main board 12 and the temperature sensor 22.

[0163] In this embodiment, a contact connection structure between the elastic ejector pin 13 and the copper sheet 23 is provided, so that when the wire controller body 1 and the temperature sensor component 2 are connected, the connection can be easily achieved; the structure for realizing the specific communication connection between the wire controller body 1 and the temperature sensor component 2 can also be set based on actual needs.

[0164] Furthermore, the opening formed on the wire controller housing 11 matches the elastic ejector pin 13 , and the wire controller housing 11 and the elastic ejector pin 13 form an internal closed space, and the wire controller mainboard 12 is disposed in the closed space.

[0165] Since the elastic ejector pin 13 needs to be in contact with the copper sheet 23, the elastic ejector pin 13 needs to be exposed on the wire controller housing 11; however, if the wire controller housing 11 is not sealed, the internal wire controller mainboard 12 is easily corroded by external materials and water vapor, resulting in a shortened service life; therefore, in order to ensure the sealing state of the wire controller housing 11; in this embodiment, the opening on the wire controller housing 11 is arranged to match the elastic ejector pin 13; so that after the elastic ejector pin 13 is arranged, the inside of the wire controller housing 11 can still remain in a sealed state.

[0166] In order to further improve the safety of the wire controller mainboard 12, the wire controller housing 11 may be further sealed and moisture-proofed, and the specific treatment method may be set based on actual needs.

[0167] Furthermore, the temperature sensor component 2 includes a sensor housing 21 and the temperature sensor 22; wherein:

[0168] The sensor housing 21 is provided with a plurality of ventilation holes 24 , and the interior of the sensor housing 21 is connected to the external environment through the ventilation holes 24 .

[0169] The temperature sensor 22 needs to detect the indoor temperature, so the space where the temperature sensor 22 is located needs to be connected to the indoor space; therefore, a ventilation hole 24 is set on the sensor housing 21 so that the interior of the sensor housing 21 is connected to the external environment, and the temperature sensor 22 can detect the indoor temperature.

[0170] The number and location of the ventilation holes 24 can be set based on actual needs.

[0171] Further, the number of the ventilation holes 24 is 2, and a ventilation channel is formed between the two ventilation holes 24;

[0172] The temperature sensor 22 is disposed on the ventilation passage.

[0173] In the present embodiment, two ventilation holes 24 are arranged so that convection can be formed between the two ventilation holes 24; the ventilation channel is the flow path of the convection; the air on the ventilation channel is constantly exchanged with the indoor environment, so the temperature on the ventilation channel can timely reflect the temperature changes of the indoor environment, and the temperature sensor 22 is arranged on the ventilation channel, so that the detection value of the temperature sensor 22 can quickly respond to the temperature changes of the indoor environment, thereby improving the detection accuracy of the temperature sensor 22.

[0174] The specific setting position of the ventilation holes 24 can be selected based on the setting relationship between the sensor component and the wire controller body 1; if the two opposite sides of the sensor housing 21 are not in contact with the wire controller housing 11, the ventilation holes 24 can be respectively set on the two opposite sides; if only two adjacent sides of the sensor housing 21 are not in contact with the wire controller housing 11, the ventilation holes 24 can be respectively set on the two adjacent sides; if only one side of the sensor housing 21 is in contact with the wire controller housing 11, the ventilation holes 24 can be set on this side.

[0175] In other embodiments, multiple ventilation holes 24 may be provided to form more ventilation channels.

[0176] Furthermore, the temperature sensor 22 includes a sensor mainboard 221 and a detection circuit 222, and the detection circuit 222 is disposed on the sensor mainboard 221;

[0177] The detection circuit 222 is disposed on the ventilation passage.

[0178] The detection circuit 222 is used to collect the indoor temperature; the sensor main board 221 is used to process the signal collected by the detection circuit 222 and send it to the wire controller main board 12.

[0179] Since the detection circuit 222 is used as a direct detection device for the indoor temperature, the detection circuit 222 is arranged on the ventilation passage to improve the accuracy of indoor temperature detection.

[0180] Furthermore, the wire controller body 1 includes a wire controller housing 11; the temperature sensor component 2 includes a sensor housing 21; wherein:

[0181] A groove is arranged on the back of the wire controller housing 11 , and the groove matches the sensor housing 21 ; the thickness of the sensor housing 21 is smaller than the thickness of the wire controller housing 11 .

[0182] The back side of the wire controller housing 11 refers to the side facing the installation wall; in this embodiment, a groove is set on the back side of the wire controller housing 11, and the sensor housing 21 is installed through the groove, so that after the installation is completed, the sensor housing 21 is relatively arranged on the back side of the wire controller housing 11; at the same time, because the sensor housing 21 matches the groove, and the thickness of the sensor housing 21 is less than the thickness of the wire controller housing 11, that is, the groove does not penetrate the wire controller housing 11 in the thickness direction, but is only reflected on the back side of the wire controller housing 11; therefore, after the installation is completed, the sensor housing 21 can be seen from the back but not from the front, which ensures the integrity of the front side of the wire controller and improves the aesthetics of the wire controller.

[0183] Further, see Figure 5 The groove is arranged at the back corner of the wire controller housing 11; the back, first side and second side of the sensor housing 21 are in contact with the groove, a ventilation hole 24 is arranged on the third side of the sensor housing 21, and a ventilation hole 24 is arranged on the fourth side of the sensor housing 21.

[0184] The groove is set at the back corner of the wire controller housing 11; after the installation is completed, the sensor housing 21 is also located at the back corner of the wire controller housing 11; under this installation method, the two side surfaces of the wire controller in the same corner direction, namely the third side surface and the fourth side surface, will not contact the wire controller housing 11, therefore, by setting the ventilation holes 24 on the third side surface and the fourth side surface, a good ventilation channel setting can be achieved.

[0185] Furthermore, the wire controller further comprises a gas sensor component, and the gas sensor component and the wire controller body 1 are detachably arranged.

[0186] It is understandable that, based on the actual needs of the unit, other sensors can be set on the wire controller, such as gas sensors and humidity sensors; gas sensors are used to detect gas components in the environment, such as TVOC (Total Volatile Organic Compounds) sensors; sensors that need to detect relevant parameters of the external environment can be set like the temperature sensor component 2; multiple sensors can be set in one component at the same time, or they can be set in different components separately.

[0187] To achieve the above object, the present invention further provides an air conditioner, characterized in that the air conditioner includes the wired controller, the unit and the indoor unit as described above.
