Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an air conditioner and a method for controlling odor removal in an air conditioner. Background Technology

[0002] With the rapid development of technology and the continuous improvement of people's quality of life, air conditioners have evolved from simple cooling and heating devices into an indispensable intelligent environmental control hub in modern homes and offices. To deeply meet people's growing demands for efficient, energy-saving, healthy, and personalized comfort experiences, air conditioning automation control systems, as the culmination of technological innovation, are gradually permeating every corner of our daily lives.

[0003] Air conditioners have internal air ducts. During operation, outside air is drawn into the ducts for temperature or humidity adjustment, and the adjusted air is then sent into the room to regulate the indoor environment. However, when odors are present inside the air conditioner (for example, odors may arise from dampness or other issues in the ducts, or various smoke particles in the indoor environment may adhere to the indoor heat exchanger and air sweeper blades, causing deterioration and odors over time in a humid environment), the air blown out of the air conditioner will also carry odors, negatively impacting the indoor environment and affecting the user experience. Summary of the Invention

[0004] The purpose of this invention is to provide an air conditioner and an odor control method for the air conditioner. By monitoring air data through an odor monitoring system, odors can be detected in a timely manner.

[0062] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other. Those skilled in the art can easily understand other advantages and effects of the present invention from the embodiments described in this specification.

The present invention can also be implemented or applied through other different embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0063] It should be noted that the accompanying drawings provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. Although the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components, the form, quantity and proportion of each component can be arbitrarily changed in actual implementation, and the layout of the components may also be more complex.

[0064] It should be noted that when describing a part as "connected" to another part, this includes not only "direct connection" but also "indirect connection" formed by placing other elements in between. Furthermore, when describing a part as "including" a certain constituent element, unless otherwise stated otherwise, it does not exclude other constituent elements, but rather means that other constituent elements may also be included.

[0065] See Figure 1 The diagram shown is a three-dimensional structural schematic of an air conditioner according to an embodiment of the present invention. The air conditioner includes an indoor unit 100 and an outdoor unit 200. The indoor unit 100 is used to regulate the temperature and humidity of the indoor air. The outdoor unit 200 is connected to the indoor unit 100 through a connecting pipe. The indoor unit 100 is generally installed indoors, and the outdoor unit 200 is generally installed outdoors.

[0066] See Figure 2 The diagram shown is a schematic representation of the internal structure of an air conditioner according to an embodiment of the present invention. The air conditioner includes a refrigerant circuit, allowing the refrigerant to circulate within a circuit consisting of a compressor, condenser, throttling device, and evaporator. One of the condenser and the evaporator is an outdoor heat exchanger, and the other is an indoor heat exchanger. Specifically, as shown... Figure 2 As shown, the indoor unit 100 mainly includes an indoor heat exchanger, an indoor fan, and an indoor fan motor. The indoor heat exchanger achieves a cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the indoor air. The indoor fan, driven by the indoor fan motor, generates airflow through the indoor heat exchanger, promoting heat exchange between the refrigerant flowing in the heat transfer tubes and the indoor air. The outdoor unit 200 mainly includes a compressor, a four-way valve, an outdoor heat exchanger, a throttling device, an outdoor fan, and an outdoor fan motor. The compressor compresses low-temperature, low-pressure refrigerant gas into high-temperature, high-pressure refrigerant gas. The four-way valve controls the flow direction of the refrigerant in the refrigerant circuit, allowing the outdoor and indoor heat exchangers to switch between condenser and evaporator functions. The outdoor heat exchanger facilitates heat exchange between the internally flowing refrigerant and the outdoor air. The throttling device restricts the flow of refrigerant. The outdoor fan, driven by the outdoor fan motor, generates airflow through the outdoor heat exchanger, promoting heat exchange between the refrigerant flowing in the heat transfer tubes and the outdoor air.

[0067] It should be noted that the air conditioner also includes a controller, which is used to control the operation of various components in the air conditioner, so that the various components of the air conditioner can operate to realize the various functions of the air conditioner.

[0068] As one optional embodiment, the air conditioner (indoor unit 100) further includes a housing and an odor monitoring system disposed within the housing, see [link to relevant documentation]. Figure 3 The diagram shown is a structural schematic of an odor monitoring system for an air conditioner provided in an embodiment of the present invention. The odor monitoring system includes an air data acquisition module 101, a control module 102, an environmental data acquisition module 103, and a cleaning module 104.

[0069] It should be noted that the air data acquisition module 101, the environmental data acquisition module 103, and the cleaning module 104 are respectively connected to the control module 102 and can communicate with the control module 102 to achieve data interaction. Through the implementation of the respective functions of the air data acquisition module 101, the control module 102, the environmental data acquisition module 103, and the cleaning module 104, as well as the mutual cooperation between the modules, the technical problems to be solved by the embodiments of the present invention can be solved, and the technical effects that the embodiments of the present invention can achieve can be achieved.

[0070] Combination Figure 3 As shown, the working principle of the odor monitoring system is as follows:

[0071] The air data acquisition module 101 is used to acquire air data and send it to the control module 102;

[0072] The control module 102 is used to generate an environmental detection command and send it to the environmental data acquisition module 103 when the air quality value is determined to be within a preset threshold range based on the air data.

[0073] The environmental data acquisition module 103 is used to acquire environmental data according to the environmental detection command and send it to the control module 102;

[0074] The control module 102 is also used to generate a first cleaning instruction based on the cleaning level corresponding to the environmental data, and send it to the cleaning module 104;

[0075] The cleaning module 104 is used to perform odor cleaning on the air conditioner according to the cleaning level in the first cleaning instruction.

[0076] The environmental data includes several environmental parameters and is divided into several categories. Each category includes at least one environmental parameter. Each environmental parameter has several value ranges and a parameter level corresponding to each value range. Each category has several cleaning levels. Each cleaning level is determined by the parameter levels corresponding to all environmental parameters included in the corresponding category.

[0077] It should be noted that the environmental data involved in the embodiments of the present invention includes several environmental parameters, and these several environmental parameters are pre-divided into several categories. Each category includes at least one of the several environmental parameters. Each environmental parameter is pre-set with several value ranges and a parameter level corresponding to each value range (i.e., one environmental parameter corresponds to several value ranges, and one value range corresponds to one parameter level). Each category of environmental data is pre-set with several cleaning levels (i.e., one category corresponds to several cleaning levels). Each cleaning level is determined by the parameter levels corresponding to all environmental parameters included in the corresponding category.

[0078] In a specific implementation of this invention, the odor monitoring system operates as follows: the air data acquisition module 101 acquires air data in real time and sends the acquired air data to the control module 102; after receiving the air data sent by the air data acquisition module 101, the control module 102 calculates the corresponding air quality value based on the received air data and determines whether the calculated air quality value is within a preset threshold range. If so (indicating the presence of an odor), an environmental detection command is generated and sent to the environmental data acquisition module 103; after receiving the environmental detection command sent by the control module 102, the environmental data acquisition module 103... The system acquires environmental data in real time according to the received environmental detection command and sends the acquired environmental data to the control module 102. After receiving the environmental data sent by the environmental data acquisition module 103, the control module 102 first determines the cleaning level corresponding to each category based on the received environmental data, and then generates a first cleaning command based on the cleaning levels corresponding to all categories in the received environmental data, and sends the generated first cleaning command to the cleaning module 104. After receiving the first cleaning command sent by the control module 102, the cleaning module 104 automatically cleans the interior of the air conditioner according to the cleaning level corresponding to each category in the received first cleaning command.

[0079] It should be noted that the functions of the air data acquisition module 101, the control module 102, and the environmental data acquisition module 103 can all be implemented by the controller of the air conditioner, or they can be implemented by each independently set module (in this case, the function of the control module 102 can still be implemented by the controller of the air conditioner). This embodiment of the invention does not make specific limitations.

[0080] For example, the air data acquisition module 101 can acquire air data by acquiring data collected by the odor sensor in real time. The air data acquisition module 101 can be an STM32 microcontroller based on an embedded system for data acquisition, and it includes I / O interfaces and communication interfaces (such as I...). 2 (e.g., C, UART, SPI, etc.) can transmit the collected air data to the control module 102 via wireless Wi-Fi or wired connection; or, the air data acquisition module 101 can be the odor sensor itself, used to collect air data in real time and send the collected air data to the control module 102.

[0081] It should be noted that the air quality data mainly includes PM2.5, PM10, CO2, TVOC, CO, and H2S. When the control module 102 calculates the corresponding air quality value based on the received air data, it can directly calculate the air quality value Z using the formula Z = w1*A + w2*B + w3*C + w4*D + w5*E + w6*F. Here, A represents PM2.5, B represents PM10, C represents CO2, D represents TVOC, E represents CO, and F represents H2S. w1, w2, w3, w4, w5, and w6 correspond to the weight values ​​of A, B, C, D, E, and F, respectively. For example, w1 = 0.4, w2 = 0.2, w3 = 0.15, w = 0.15, w5 = 0.05, and w6 = 0.05. It is understood that the units of the parameters in the formula may not be consistent; only the numerical value of each parameter is used in the calculation.

[0082] For example, the odor sensor can be one of CCS811, SGP30, MQ series (MQ-2, MQ-3, MQ-7, MQ-135), TGS series (TGS-2600, TGS-822, TGS-813), CCS811, or EasySens.

[0083] Understandably, odor sensors are typically installed inside the air conditioner at the air outlet, via I... 2Standard interfaces such as C or UART are connected to the air data acquisition module 101 and integrated into the control board of the air conditioner. Data collected by the odor sensor can be transmitted to the air data acquisition module 101 for processing through these interfaces.

[0084] For example, the environmental data acquisition module 103 can be a multi-functional sensor used to collect environmental data (mainly including temperature, humidity, odor and particulate matter) in real time, and transmit the collected environmental data to the control module 102 via wireless Wi-Fi or wired means.

[0085] For example, the multifunctional sensor can be BME680, Sensirion combination (SGP40 (odor detection) + SHTC3 (temperature and humidity detection) + SPS30 (particulate matter detection)), Honeywell combination (HPM32322550 (particulate matter detection) + HIH series (temperature and humidity detection) + MiCS-5524 (odor detection)) or Amphenol combination (TGS2600 (odor detection) + HDC1080 (temperature and humidity detection) + PM2.5 sensor (particulate matter detection)), etc.

[0086] Understandably, multi-functional sensors can typically be installed at the condensate drain pump of the air conditioner.

[0087] An air conditioner provided in this embodiment of the invention includes an odor monitoring system. The odor monitoring system comprises an air data acquisition module 101, a control module 102, an environmental data acquisition module 103, and a cleaning module 104. In practical applications, the air data acquisition module 101 can acquire air data in real time and upload it to the control module 102. The control module 102 can determine whether the corresponding air quality value is within a preset threshold range based on the air data, thereby quickly detecting odors inside the air conditioner caused by water accumulation or other reasons. When the air quality value is determined to be within the preset threshold range, the control module 102 can acquire environmental data in real time through the environmental data acquisition module 103 and generate a first cleaning command based on the acquired environmental data, sending it to the cleaning module 104. This allows the cleaning module 104 to automatically clean the air conditioner to remove odors. This real-time monitoring and rapid response mechanism can promptly address odor problems, effectively remove odors, ensure fresh air from the air conditioner, thereby preventing odors from affecting the indoor environment, improving indoor air quality, and enhancing user experience.

[0088] As one optional embodiment, the environmental data includes temperature, humidity, odor, and particulate matter, with temperature, humidity, and odor classified into a first category and particulate matter classified into a second category; the control module 102 generates a first cleaning instruction based on the cleaning level corresponding to the environmental data, specifically including:

[0089] Based on the range of temperature, humidity, and odor parameter values ​​contained in the first category, determine the corresponding parameter levels for temperature, humidity, and odor, and determine the cleaning level corresponding to the first category based on the corresponding parameter levels for temperature, humidity, and odor.

[0090] Based on the range of parameter values ​​of the particles contained in the second category, determine the parameter level corresponding to the particles, and determine the cleaning level corresponding to the second category based on the parameter level corresponding to the particles.

[0091] A first cleaning instruction is generated based on the cleaning level corresponding to the first category and the cleaning level corresponding to the second category.

[0092] It should be noted that the environmental data involved in the embodiments of the present invention mainly includes four environmental parameters: temperature, humidity, odor, and particulate matter. These four environmental parameters are pre-divided into two categories: the first category and the second category. The first category includes temperature, humidity, and odor, while the second category includes particulate matter. For each of these four environmental parameters, three different value ranges and three parameter levels (high, medium, and low) corresponding to the three value ranges are pre-set. For each category of environmental data, three cleaning levels (high, medium, and low) are pre-set.

[0093] Combination Figure 4 The diagram shows the workflow of a control module for an odor monitoring system according to an embodiment of the present invention. Based on the above embodiment, in specific implementation of this embodiment, when the control module 102 generates a first cleaning instruction according to the cleaning level corresponding to the environmental data, it can first determine the parameter level corresponding to temperature, humidity, and odor based on the value ranges of the temperature, humidity, and odor parameters included in the first category of the environmental data, respectively. Then, based on these parameter levels, it further determines the cleaning level corresponding to the first category. Figure 4 Step S101 (shown); and, based on the range of parameter values ​​of particulate matter included in the second category of environmental data, determining the parameter level corresponding to the particulate matter, and further determining the cleaning level corresponding to the second category based on the parameter level corresponding to the particulate matter. Figure 4Step S102 (as shown); then, based on the determined cleaning level corresponding to the first category and the cleaning level corresponding to the second category, a first cleaning instruction is generated ( Figure 4 (Step S103 shown).

[0094] For example, in the first category, the three temperature ranges and their corresponding high, medium, and low parameter settings are: 15℃~22℃, corresponding to the low parameter setting, indicating a comfortable temperature where no additional adjustment is needed; 23℃~26℃, corresponding to the medium parameter setting, indicating a slightly high temperature that may require cooling; and 27℃ and above, corresponding to the high parameter setting, indicating a high temperature that requires active cooling. Similarly, the three humidity ranges and their corresponding high, medium, and low parameter settings are: 30%~50%, corresponding to the low parameter setting, indicating comfortable humidity that requires no special adjustment. Special treatment is required; 51% to 70%, corresponding to the medium parameter setting, indicates that the humidity is too high and dehumidification is needed; 71% and above, corresponding to the high parameter setting, indicates that the humidity is too high and active dehumidification is needed; the three value ranges of odor and the corresponding high, medium and low parameter settings are as follows: 0 to 50 ppb, corresponding to the low parameter setting, indicates that the air quality is good and there is no odor; 51 ppb to 300 ppb, corresponding to the medium parameter setting, indicates that the air quality is average and there is a slight odor; 301 ppb to 500 ppb and above, corresponding to the high parameter setting, indicates that the air quality is poor and there is a noticeable odor.

[0095] Based on this, when the control module 102 further determines the cleaning level corresponding to the first category according to the parameter levels corresponding to temperature, humidity, and odor, it includes the following situations: If there are three low parameter levels, two low parameter levels and one medium parameter level, or one low parameter level and two medium parameter levels among the parameter levels corresponding to temperature, humidity, and odor, then the cleaning level corresponding to the first category is determined to be a low cleaning level; if there are three medium parameter levels... If there are two high parameter settings (one of which is a low parameter setting and / or a medium parameter setting), or if there are three high parameter settings, then the cleaning setting corresponding to the first category is determined to be a high cleaning setting. For example, when the detected temperature is 28℃ (high parameter setting), the humidity is 30% (low parameter setting), and the odor is 250ppb (medium parameter setting), the cleaning setting corresponding to the first category is determined to be a medium cleaning setting.

[0096] For example, in the second category, the three ranges of particulate matter and the corresponding high, medium, and low parameter levels for these three ranges include: 0–35 μg / m³. 3 This corresponds to a low parameter setting, indicating a low particulate matter concentration and good air quality; 36 μg / m³ 3 ~75μg / m 3 This corresponds to the medium parameter setting, indicating a moderate particulate matter concentration and some air quality issues; 76 μg / m³ 3 Levels of 1 and above correspond to high parameter settings, indicating a high concentration of particulate matter, poor air quality, and the need for immediate action.

[0097] Based on this, when the control module 102 further determines the cleaning level corresponding to the second category according to the parameter level corresponding to the particulate matter, it includes the following cases: if the parameter level corresponding to the particulate matter is a low parameter level, then the cleaning level corresponding to the second category is determined to be a low cleaning level; if the parameter level corresponding to the particulate matter is a medium parameter level, then the cleaning level corresponding to the second category is determined to be a medium cleaning level; if the parameter level corresponding to the particulate matter is a high parameter level, then the cleaning level corresponding to the second category is determined to be a high cleaning level.

[0098] It should be noted that, in this embodiment of the invention, by dividing the range of values ​​for temperature, humidity, odor, and particulate matter and setting different parameter levels accordingly, the values ​​of environmental parameters can be mapped from the range to the parameter level. By classifying temperature, humidity, odor, and particulate matter into categories and setting different cleaning levels for each category, the values ​​of environmental parameters can be mapped from the range to the parameter level to the cleaning level. This enables more precise cleaning, avoids unnecessary over-cleaning, and saves cleaning resources and energy. Furthermore, it allows for different cleaning measures at different levels for different types of pollution sources, effectively improving the cleaning effect. Moreover, this on-demand cleaning method can utilize system resources more efficiently and reduce energy consumption and maintenance costs.

[0099] See Figure 5 The diagram shown is a structural schematic of an odor monitoring system for an air conditioner according to another embodiment of the present invention. As one optional embodiment, the cleaning module 104 includes a blower unit 1041 and a negative ion unit 1042. The cleaning module 104 performs odor cleaning treatment on the air conditioner according to the cleaning setting in the first cleaning instruction, specifically including:

[0100] Obtain the cleaning level corresponding to the first category and the cleaning level corresponding to the second category in the first cleaning instruction;

[0101] The operating power of the blower unit 1041 is adjusted to the first operating power according to the cleaning level corresponding to the first category, and the blower unit 1041 is controlled to operate according to the first operating power to clean the air conditioner of odors.

[0102] The emission frequency of the negative ion unit 1042 is adjusted to the first emission frequency according to the cleaning level corresponding to the second category, and the negative ion unit 1042 is controlled to operate at the first emission frequency to clean the air conditioner of odors.

[0103] Based on the above embodiments, in specific implementation of this embodiment, the cleaning module 104 mainly consists of the blowing unit 1041 and the negative ion unit 1042. When the cleaning module 104 performs odor cleaning treatment on the air conditioner according to the cleaning level in the first cleaning instruction, it can first obtain the cleaning level corresponding to the first category and the cleaning level corresponding to the second category in the first cleaning instruction; then adjust the operating power of the blowing unit 1041 to reach the first operating power according to the cleaning level corresponding to the first category, and control the blowing unit 1041 to operate according to the adjusted first operating power to automatically clean the odor inside the air conditioner; and adjust the emission frequency of the negative ion unit 1042 to reach the first emission frequency according to the cleaning level corresponding to the second category, and control the negative ion unit 1042 to operate according to the adjusted first emission frequency to automatically clean the odor inside the air conditioner.

[0104] For example, the blowing unit 1041 can be implemented using a fan, which can generally be installed at the condensate drain pump to blow air towards the drain pipe; the negative ion unit 1042 can be implemented using a negative ion generator, which can generally be installed at the condensate drain pump.

[0105] For example, when the cleaning level corresponding to the first category is low cleaning level, the first operating power can be 50% of the maximum operating power of the blower unit 1041 (e.g., fan); when the cleaning level corresponding to the first category is medium cleaning level, the first operating power can be 75% of the maximum operating power of the blower unit 1041 (e.g., fan); when the cleaning level corresponding to the first category is high cleaning level, the first operating power can be the maximum operating power of the blower unit 1041 (e.g., fan).

[0106] For example, when the cleaning level corresponding to the second category is low, the first emission frequency can be 1Hz to 5Hz, that is, the negative ion unit 1042 (e.g., a negative ion generator) can be controlled to emit intermittently between 1Hz and 5Hz; when the cleaning level corresponding to the second category is medium, the first emission frequency can be 5Hz to 10Hz, that is, the negative ion unit 1042 (e.g., a negative ion generator) can be controlled to emit continuously between 5Hz and 10Hz; when the cleaning level corresponding to the second category is high, the first emission frequency can be 15Hz to 20Hz, that is, the negative ion unit 1042 (e.g., a negative ion generator) can be controlled to emit continuously between 15Hz and 20Hz.

[0107] It should be noted that although air conditioners generally have a fan (such as the indoor fan of an air conditioner), and the function of the blowing unit 1041 can be achieved by using the fan of the air conditioner itself, the blowing unit 1041 additionally provided in this embodiment of the invention has the characteristic of being ready to use immediately. When the temperature or humidity is slightly exceeded, the blowing unit 1041 can be quickly triggered to increase air flow and achieve the effect of temporary cooling or dehumidification.

[0108] It should be noted that, according to the different cleaning levels corresponding to different categories, the embodiments of the present invention perform different controls, which can accurately adjust the working state of the blower unit 1041 and the negative ion unit 1042 to ensure targeted cleaning treatment according to the needs of the actual environment.

[0109] See Figure 6 The diagram shown is a structural schematic of an odor monitoring system for an air conditioner according to another embodiment of the present invention. As one optional embodiment, the preset threshold range is determined by a first preset threshold and a second preset threshold, wherein the first preset threshold is less than the second preset threshold. The odor monitoring system also includes a device self-test module 105.

[0110] The control module 102 is also used to generate a device detection command and send it to the device self-test module 105 when the air quality value is determined to exceed the second preset threshold based on the air data.

[0111] The device self-test module 105 is used to obtain the current operating parameters of the cleaning module 104 according to the device test command, and send them to the control module 102;

[0112] The control module 102 is also used to determine whether the cleaning module 104 is in normal operating condition based on the current operating parameters. If so, it generates a second cleaning instruction and sends it to the cleaning module 104. In the second cleaning instruction, the cleaning level corresponding to each category is the highest level.

[0113] The cleaning module 104 is also used to perform odor cleaning treatment on the air conditioner according to the cleaning level in the second cleaning instruction.

[0114] It should be noted that the preset threshold range can be limited by the first preset threshold and the second preset threshold, and if the first preset threshold is set to be less than the second preset threshold, then the preset threshold range can be [first preset threshold, second preset threshold].

[0115] It should be noted that the odor monitoring system also includes the device self-test module 105, which is also connected to the control module 102 and can communicate with the control module 102 to achieve data interaction.

[0116] Based on the above embodiments, the specific working process of the odor monitoring system in the specific implementation of this embodiment is as follows: the air data acquisition module 101 acquires air data in real time and sends the acquired air data to the control module 102; after receiving the air data sent by the air data acquisition module 101, the control module 102 calculates the corresponding air quality value based on the received air data, and determines whether the calculated air quality value is within a preset threshold range. If it is determined that the calculated air quality value is not within the preset threshold range and exceeds a second preset threshold (indicating the presence of an odor), a device detection command is generated and sent to the device self-test module 105; after receiving the device detection command sent by the control module 102, the device self-test module 105 performs the following steps according to the received device detection command: The system acquires the current operating parameters of the cleaning module 104 in real time and sends the acquired current operating parameters to the control module 102. After receiving the current operating parameters sent by the device self-test module 105, the control module 102 determines whether the cleaning module 104 is in normal working condition based on the received current operating parameters. If so, it generates a second cleaning instruction (each category in the second cleaning instruction corresponds to the highest cleaning level, that is, the cleaning level corresponding to the first category is the high cleaning level, and the cleaning level corresponding to the second category is the high cleaning level), and sends the generated second cleaning instruction to the cleaning module 104. After receiving the second cleaning instruction sent by the control module 102, the cleaning module 104 automatically cleans the interior of the air conditioner according to the cleaning level corresponding to each category in the received second cleaning instruction.

[0117] It should be noted that the functions of the air data acquisition module 101, the control module 102, the environmental data acquisition module 103, and the device self-test module 105 can all be implemented by the controller of the air conditioner, or they can be implemented by each independently set module (in this case, the function of the control module 102 can still be implemented by the controller of the air conditioner). This embodiment of the invention does not make specific limitations.

[0118] Understandably, when the control module 102 determines whether the calculated air quality value is within the preset threshold range, if it determines that the calculated air quality value is not within the preset threshold range and is less than the first preset threshold (indicating that there is no odor), then it is not necessary to clean the air conditioner.

[0119] It should be noted that before cleaning the air conditioner, the self-test module 105 can be used to confirm whether the air conditioner is operating normally. The cleaning operation will only be performed after the equipment is confirmed to be operating normally. This can avoid ineffective or harmful cleaning in the event of equipment failure.

[0120] It should be noted that, by setting the device self-test module 105 in this embodiment of the invention, the operating status of the air conditioner can be self-tested periodically or in real time, thereby discovering potential problems in a timely manner and dealing with them promptly, which helps to prevent air conditioner malfunctions, reduce air conditioner wear and tear, and extend the service life of the air conditioner.

[0121] As one optional embodiment, the device self-test module 105 obtains the current operating parameters of the cleaning module 104 according to the device test command, specifically including:

[0122] The current operating power of the blowing unit 1041 and the current emission frequency of the negative ion unit 1042 are obtained according to the device detection command.

[0123] The control module 102 determines whether the cleaning module 104 is in normal operating condition based on the current operating parameters, specifically including:

[0124] Determine whether the blower unit 1041 is in normal operating condition based on the first operating power and the current operating power;

[0125] Determine whether the negative ion unit 1042 is in normal operating condition based on the first emission frequency and the current emission frequency;

[0126] When both the blower unit 1041 and the negative ion unit 1042 are in normal operating condition, the cleaning module 104 is determined to be in normal operating condition; otherwise, the cleaning module 104 is determined to be in abnormal operating condition.

[0127] Combination Figure 7The diagram shown is a flowchart of the control module of an odor monitoring system according to another embodiment of the present invention. Based on the above embodiment, the cleaning module 104 includes the blowing unit 1041 and the negative ion unit 1042. The current operating parameters of the cleaning module 104 are the current operating power of the blowing unit 1041 and the current emission frequency of the negative ion unit 1042. Therefore, in specific implementation of this embodiment, when the device self-test module 105 obtains the current operating parameters of the cleaning module 104 according to the device detection command, it can obtain the current operating power of the blowing unit 1041 and the current emission frequency of the negative ion unit 1042 in real time and send them to the control module 102. When the control module 102 determines whether the cleaning module 104 is in normal operating condition based on the current operating parameters sent by the device self-test module 105, it can determine whether the blowing unit 1041 is in normal operating condition based on the first operating power of the blowing unit 1041 (the first operating power reached by the blowing unit 1041 after real-time adjustment) and the current operating power. Figure 7 Step S201 shown); and, based on the first emission frequency of the negative ion unit 1042 (the first emission frequency reached by the negative ion unit 1042 after real-time adjustment) and the current emission frequency, determining whether the negative ion unit 1042 is in normal operating condition. Figure 7 (See step S202); then, based on the operating status of the blower unit 1041 and the negative ion unit 1042, it is further determined whether the cleaning module 104 is in a normal operating state: when both the blower unit 1041 and the negative ion unit 1042 are in a normal operating state, the cleaning module 104 is determined to be in a normal operating state; otherwise (i.e., at most one of the blower unit 1041 and the negative ion unit 1042 is in a normal operating state), the cleaning module 104 is determined to be in an abnormal operating state. Figure 7 (Step S203 shown).

[0128] As one optional embodiment, the control module 102 determines whether the blower unit 1041 is in normal operating condition based on the first operating power and the current operating power, specifically including:

[0129] Calculate the power difference between the first operating power and the current operating power;

[0130] When the power difference is within a preset power range, the blower unit 1041 is determined to be in normal operating condition; otherwise, the blower unit 1041 is determined to be in abnormal operating condition.

[0131] Combination Figure 8The diagram shown is a flowchart of the control module of an odor monitoring system according to another embodiment of the present invention. Based on the above embodiment, in specific implementation of this embodiment, when the control module 102 determines whether the blower unit 1041 is in normal operating condition based on the first operating power and the current operating power of the blower unit 1041, it can first calculate the power difference between the first operating power and the current operating power of the blower unit 1041. Figure 8 (See step S2011); then determine whether the calculated power difference is within the preset power range. Figure 8 As shown in step S2012), if the calculated power difference is within a preset power range, then the blower unit 1041 is determined to be in normal operating condition. Figure 8 If step S2013 is not specified, otherwise (i.e., if the calculated power difference is outside the preset power range), the blower unit 1041 is determined to be in an abnormal operating state. Figure 8 (Step S2014 shown).

[0132] For example, the preset power range can be obtained through experimental testing when the air conditioner leaves the factory, or it can be obtained through other means. This embodiment of the invention does not make any specific limitations.

[0133] It should be noted that, in this embodiment of the invention, by setting a preset power range corresponding to the power difference of the blower unit 1041, the operating status of the blower unit 1041 is determined to be normal. This can quickly detect the fault or performance degradation of the blower unit 1041, thereby reducing the impact of system failure on the user.

[0134] As one optional embodiment, the control module 102 determines whether the negative ion unit 1042 is in normal operating condition based on the first emission frequency and the current emission frequency, specifically including:

[0135] Calculate the frequency difference between the first transmission frequency and the current transmission frequency;

[0136] When the frequency difference is within a preset frequency range, the negative ion unit 1042 is determined to be in normal operating condition; otherwise, the negative ion unit 1042 is determined to be in abnormal operating condition.

[0137] Combination Figure 9The diagram shown is a flowchart of the control module of an odor monitoring system according to another embodiment of the present invention. Based on the above embodiment, in specific implementation of this embodiment, when the control module 102 determines whether the negative ion unit 1042 is in normal operating condition based on the first emission frequency and the current emission frequency of the negative ion unit 1042, it can first calculate the frequency difference between the first emission frequency and the current emission frequency of the negative ion unit 1042. Figure 9 (See step S2021); then determine whether the calculated frequency difference is within the preset frequency range. Figure 9 As shown in step S2022), if the calculated frequency difference is within a preset frequency range, then the negative ion unit 1042 is determined to be in normal operating condition. Figure 9 If step S2023 is not specified, otherwise (i.e., if the calculated frequency difference is outside the preset frequency range), the negative ion unit 1042 is determined to be in an abnormal operating state. Figure 9 (Step S2024 shown).

[0138] For example, the preset frequency range can be obtained through experimental testing when the air conditioner leaves the factory, or it can be obtained through other means. This embodiment of the invention does not make any specific limitations.

[0139] It should be noted that, in this embodiment of the invention, by setting a preset frequency range corresponding to the frequency difference of the negative ion unit 1042, the operating status of the negative ion unit 1042 is determined to be normal. This can quickly detect faults or performance degradation of the negative ion unit 1042, thereby reducing the impact of system failures on users.

[0140] As one optional embodiment, the cleaning module 104 performs odor cleaning on the air conditioner according to the cleaning level in the second cleaning instruction, specifically including:

[0141] Obtain the cleaning level corresponding to the first category and the cleaning level corresponding to the second category in the second cleaning instruction;

[0142] Adjust the operating power of the blower unit 1041 to the maximum operating power according to the cleaning level corresponding to the first category, and control the blower unit 1041 to operate at the maximum operating power to clean the air conditioner of odors.

[0143] Adjust the emission frequency of the negative ion unit 1042 to the maximum emission frequency according to the cleaning level corresponding to the second category, and control the negative ion unit 1042 to operate at the maximum emission frequency in order to clean the air conditioner of odors.

[0144] Based on the above embodiments, the cleaning module 104 includes the blowing unit 1041 and the negative ion unit 1042. Therefore, in specific implementation of this embodiment, when the cleaning module 104 performs odor cleaning on the air conditioner according to the cleaning level in the second cleaning instruction, it can first obtain the cleaning level corresponding to the first category and the cleaning level corresponding to the second category in the second cleaning instruction (each category in the second cleaning instruction corresponds to the highest cleaning level, that is, the cleaning level corresponding to the first category is a high cleaning level, and the cleaning level corresponding to the second category is also a high cleaning level); then according to the first... The high-cleaning setting corresponding to the category adjusts the operating power of the blower unit 1041 to the maximum operating power, and controls the blower unit 1041 to operate at the adjusted maximum operating power to automatically clean the air conditioner interior of the air conditioner; and the high-cleaning setting corresponding to the second category adjusts the emission frequency of the negative ion unit 1042 to the maximum emission frequency, and controls the negative ion unit 1042 to operate at the adjusted maximum emission frequency. For example, the negative ion unit 1042 can be controlled to continuously emit between 15Hz and 20Hz to automatically clean the air conditioner interior of the air conditioner.

[0145] It should be noted that, in this embodiment of the invention, by sending a second cleaning command to the cleaning module 104, the blower unit 1041 is controlled to operate at maximum power and the negative ion unit 1042 is controlled to operate at maximum emission frequency. This maximized cleaning setting ensures that the system can handle relatively serious pollution situations and achieve a more thorough cleaning effect.

[0146] See Figure 10 The diagram shown is a structural schematic of an odor monitoring system for an air conditioner according to another embodiment of the present invention. As one optional embodiment, the odor monitoring system further includes an alarm module 106.

[0147] The control module 102 is also used to generate an alarm command and send it to the alarm module 106 when it is determined that the cleaning module 104 is in an abnormal operating state.

[0148] The alarm module 106 is used to issue an alarm according to the alarm command.

[0149] It should be noted that the odor monitoring system also includes the alarm module 106, which is also connected to the control module 102 and can communicate with the control module 102 to achieve data interaction.

[0150] Based on the above embodiments, the specific working process of the odor monitoring system in the specific implementation of this embodiment is as follows: the air data acquisition module 101 acquires air data in real time and sends the acquired air data to the control module 102; after receiving the air data sent by the air data acquisition module 101, the control module 102 calculates the corresponding air quality value based on the received air data, and determines whether the calculated air quality value is within a preset threshold range. If it is determined that the calculated air quality value is not within the preset threshold range and exceeds a second preset threshold (indicating the presence of an odor), a device detection command is generated and sent to the device self-test module 105; the device self-test module... After receiving the device detection command sent by the control module 102, block 105 acquires the current operating parameters of the cleaning module 104 in real time according to the received device detection command, and sends the real-time acquired current operating parameters to the control module 102; after receiving the current operating parameters sent by the device self-test module 105, the control module 102 determines whether the cleaning module 104 is in a normal operating state according to the received current operating parameters. When it is determined that the cleaning module 104 is in an abnormal operating state, an alarm command is generated and sent to the alarm module 106; after receiving the alarm command sent by the control module 102, the alarm module 106 issues an alarm according to the received alarm command.

[0151] For example, the alarm module 106 can generate an alarm through sound alarm, light alarm, or other means.

[0152] It should be noted that after determining that the cleaning module 104 is in an abnormal operating state, the control module 102 can not only send an alarm command to the alarm module 106 to generate an alarm, but also actively control the air conditioner to shut down, thereby protecting the air conditioner.
