Description

Technical Field

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

[0002] Odors from air conditioners, especially from the indoor unit, are a common problem when using air conditioning for cooling. A pungent smell may be noticeable, particularly when the air conditioner is first turned on.

[0003] Dust, lint, dander, and other suspended particles in indoor air easily adhere to and accumulate on the surfaces or in the crevices of components such as the air conditioner's indoor unit fan wheel, evaporator coils / fins, condensate tray, and filter. When indoor air remains in a high-humidity state for extended periods, or when condensate is not completely drained after the air conditioner is turned off, bacteria, mold, and other microorganisms carried in these wetted deposits will rapidly multiply under suitable temperature conditions, decomposing and producing organic matter. When the air conditioner is restarted, the indoor unit's fan wheel blows out the gaseous products of microbial metabolism, resulting in a pervasive sour, sweaty, or even musty odor. Additionally, refrigerant leaks, substandard evaporator coil / fin coating quality, and aging component materials can also produce odors. While these issues can be mitigated to some extent by improving the quality of air conditioning products, odors generated by microbial growth and metabolism are often difficult to avoid. These odors pose a significant threat to human health, particularly the respiratory system, and may trigger respiratory infections, rhinitis, asthma, and other diseases.

[0004] Therefore, air conditioners still need improvement. Summary of the Invention

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an odor removal control method, an odor removal device, and an air conditioner. The odor removal control method automatically detects the odor concentration inside the air conditioner and controls the cleaning components to perform cleaning, thereby achieving automated removal of odors from the air conditioner.

[0006] According to a first aspect of the present invention, an odor control method is used in an air conditioner, and the odor control method includes: step S10, detecting the concentration of odor gas inside the air conditioner and the operating status of the air conditioner's refrigerant circulation system; step S20, if the detected odor gas concentration reaches a preset threshold and the air conditioner's refrigerant circulation system is in a closed state, then activating a cleaning component, spraying a cleaning agent into the air conditioner, and spraying water into the air conditioner after a first preset time; step S30, repeating steps S10 and S20 until the detected odor gas concentration is lower than the preset threshold; and step S40, raising the internal temperature of the air conditioner to dry it.

[0007] According to the odor removal control method of the present invention, the odor concentration inside the air conditioner is automatically detected. If the detected odor gas concentration reaches a preset threshold and the refrigerant circulation system of the air conditioner is in a closed state, the cleaning component is turned on to clean the air conditioner. If the odor concentration still reaches the preset threshold after cleaning, the cleaning component is turned on again until the detected odor gas concentration is lower than the preset threshold. Then the internal temperature of the air conditioner is increased to dry it, thereby realizing the automatic removal of odors from the air conditioner.

[0008] In some embodiments, step S20 further includes: determining the cleaning level of the cleaning component based on the degree to which the odor gas concentration exceeds a preset threshold and preset data. The cleaning component has multiple cleaning levels, and the cleaning parameters of the multiple cleaning levels are different. The cleaning parameters include at least one of the spraying time of the cleaning agent, a first preset time, and the spraying time of water.

[0009] In some embodiments, in step S20, the interval corresponding to the detection result of odor gas concentration reaching a preset threshold is divided into multiple sub-intervals. The multiple sub-intervals include a first sub-interval to an Nth sub-interval. From the first sub-interval to the Nth sub-interval, the degree to which the detection result of odor gas concentration exceeds the preset threshold increases, the corresponding cleaning level increases, and the corresponding cleaning parameters increase.

[0010] In some embodiments, the preset data includes at least one of the following: a table indicating the relationship between odor gas concentration and cleaning parameters; historical operating data of the air conditioner; historical operating parameters of multiple air conditioners of the same model as the air conditioner; and experimental test data of an air conditioner prototype of the same model as the air conditioner.

[0011] In some embodiments, in step S20, the indoor air outlet of the air conditioner is closed, and in step S40, the indoor air outlet of the air conditioner is opened, and the indoor fan of the air conditioner rotates.

[0012] In some embodiments, the odor control method further includes step S50: if the detected odor gas concentration does not reach a preset threshold and the refrigerant circulation system of the air conditioner is in a closed state, determine whether to turn on the cleaning component based on environmental parameters, or turn on the cleaning component every third preset time interval, or remind the user to manually turn on the cleaning component based on at least one of the environmental parameters and the time interval from the last cleaning.

[0013] In some embodiments, the odor control method further includes step S60: if the detected odor gas concentration does not reach a preset threshold, when the refrigerant circulation system of the air conditioner is turned on in cooling mode, the air conditioner first runs in dehumidification mode for a fourth preset time before entering cooling mode.

[0014] In some embodiments, the odor control method further includes step S70: if the detected odor gas concentration reaches a preset threshold and the refrigerant circulation system of the air conditioner is in the open state, output a prompt message to remind the user that the odor gas concentration exceeds the standard.

[0015] According to a second aspect of the present invention, an odor removal device is used in an air conditioner and includes: a first detection component for detecting the concentration of odorous gases inside the air conditioner; a second detection component for detecting the operating status of the refrigerant circulation system of the air conditioner; a cleaning component including a first liquid storage structure, a second liquid storage structure, a valve structure, and a nozzle, wherein the first liquid storage structure and the second liquid storage structure are respectively used to hold cleaning agent and water, and the valve structure is used to control the on / off connection between the first liquid storage structure and the nozzle, and to control the on / off connection between the second liquid storage structure and the nozzle; a heating component for heating the interior of the air conditioner; and a control component that communicates with the first detection component, the second detection component, the valve structure, and the heating component, and controls the valve structure and the heating component according to the detection results of the first detection component and the second detection component.

[0016] According to embodiments of the present invention, the odor removal device, through the coordinated operation of a first detection component, a second detection component, a cleaning component, a heating component, and a control component, facilitates the maintenance of the cleanliness of the air conditioner and the removal of odors inside the air conditioner.

[0017] According to a third aspect embodiment of the present invention, the air conditioner has a refrigerant circulation system, which includes a compressor, a commutator, an indoor heat exchanger, an outdoor heat exchanger, and a throttling element. The air conditioner also includes a housing, a water tray, an electrical control box, and an odor removal device according to a second aspect embodiment of the present invention. The indoor heat exchanger, the water tray, the first detection component, the nozzle, and the heating component are all disposed within the housing. The water tray is disposed below the indoor heat exchanger and has a drain outlet. The control component communicates with the electrical control box.

[0018] According to the embodiments of the present invention, by employing the above-described odor removal device, the air conditioner can be kept clean and odors inside the air conditioner can be removed.

[0019] In some embodiments, the detection head of the first detection component is spaced between the indoor heat exchanger and the water receiving pan, and is located near the drain outlet.

[0020] In some embodiments, at least one of the first liquid storage structure and the second liquid storage structure is detachably disposed outside the housing.

[0021] In some embodiments, the air inlet of the air conditioner is provided with a detachable filter structure. The odor removal device has a first main road, a second main road, a first branch road, and a second branch road. The first branch road and the second branch road are both connected to one end of the first main road.

Detailed Implementation

[0034] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided, but those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0036] Hereinafter, with reference to the accompanying drawings, a method for controlling odor removal according to a first aspect of the present invention will be described. This method can be used in an air conditioner.

[0037] like Figure 1 As shown, the odor control method includes: Step S10, detecting the concentration of odor gas inside the air conditioner and the operating status of the air conditioner's refrigerant circulation system; Step S20, if the detected odor gas concentration reaches a preset threshold, i.e., the detected odor gas concentration is greater than or equal to the preset threshold, and the air conditioner's refrigerant circulation system is in a closed state, then the cleaning component is turned on, the cleaning component sprays cleaning agent into the air conditioner, and after the spraying is completed and left to stand for a first preset time, water is sprayed into the air conditioner; Step S30, repeating steps S10 and S20 until the detected odor gas concentration is lower than the preset threshold; Step S40, raising the internal temperature of the air conditioner to dry it.

[0038] The first preset duration starts counting from the end of the cleaning agent spraying process. The first preset duration refers to the settling time after the cleaning agent spraying process ends. It can be understood as the interval between the end of the cleaning agent spraying process and the moment when water is sprayed into the air conditioner. The first preset duration can be set according to actual needs. Similarly, the spraying time of the cleaning agent and the spraying time of the water can also be set according to actual needs.

[0039] It is evident that automatically detecting the concentration of odor gases inside the air conditioner to determine whether to activate the cleaning component, ensuring that cleaning is only performed when odor removal is needed, enhances the air conditioner's intelligence and saves energy during cleaning. If the detected odor gas concentration reaches a preset threshold, indicating a severe odor, the cleaning component will activate if the refrigerant circulation system is off to remove the odor. This cleaning process does not affect the refrigerant circulation system's performance. During cleaning, the cleaning component first sprays cleaning agent into the air conditioner, allowing it to fully contact and penetrate the air after a first preset time. For the cleaning process, water is sprayed inside the air conditioner to ensure it functions effectively. This water spray washes away dirt and cleaning agent from various components, improving detection accuracy. After each cleaning cycle, the concentration of odorous gases inside the air conditioner is checked again. If the concentration still reaches the preset threshold and the refrigerant circulation system is off, the air conditioner is cleaned again until the detected odor concentration is below the preset threshold. After at least one cleaning cycle, if the detected odor concentration is below the preset threshold, the internal temperature of the air conditioner is increased to dry it. This reduces the risk of bacteria and mold growth caused by water residue, effectively eliminating odor sources and keeping the air conditioner's interior clean.

[0040] Clearly, from the time the odor gas concentration inside the air conditioner reaches a preset threshold until it falls below that threshold, the air conditioner has been cleaned at least once. The cleaning process in step S20 can be understood as performing one cleaning operation on the air conditioner, i.e., in a single cleaning, cleaning agent is sprayed into the air conditioner first, followed by water. In other words, in step S30, if the detected odor gas concentration is below the preset threshold during the first repetition of step S10, then step S20 is unnecessary. In this case, the air conditioner has been cleaned once between the time the odor gas concentration reaches the preset threshold and the time it falls below that threshold. However, if the detected odor gas concentration is still greater than or equal to the preset threshold during the first repetition of step S10 in step S30, then step S20 must be performed until the detected odor gas concentration falls below the preset threshold. In this case, the air conditioner has been cleaned multiple times between the time the odor gas concentration reaches the preset threshold and the time it falls below that threshold.

[0041] It can be understood that the refrigerant circulation system of an air conditioner can include a compressor, an indoor heat exchanger, a throttling element, and an outdoor heat exchanger. The air conditioner can execute cooling and / or heating modes through this refrigerant circulation system. For example, in cooling mode, the high-temperature refrigerant discharged from the compressor first enters the outdoor heat exchanger, flows out from the outdoor heat exchanger, then enters the throttling element, passes through the throttling element, then enters the indoor heat exchanger, and then flows back to the compressor, thus continuously circulating to achieve continuous cooling of the indoor environment. In heating mode, the high-temperature refrigerant discharged from the compressor first enters the indoor heat exchanger, flows out from the indoor heat exchanger, then enters the throttling element, passes through the throttling element, then enters the outdoor heat exchanger, and then flows back to the compressor, thus continuously circulating to achieve continuous heating of the indoor environment. When the refrigerant circulation system is in a closed state, it can be understood that the compressor is in a powered-off state, or that the refrigerant circulation system is in a power-off state.

[0042] For example, if the concentration of odorous gas is detected to reach a preset threshold and the refrigerant circulation system of the air conditioner is in a closed state, the cleaning component is turned on to clean the air conditioner. The cleaning component first sprays cleaning agent into the air conditioner for 1 minute, and after spraying the cleaning agent, it stands for 10 minutes. Then, it sprays water into the air conditioner for 2 minutes to allow the pure water to fully wash away the contaminants soaked in the cleaning solution. The odor concentration in the air conditioner is detected again. If the odorous gas concentration reaches the preset threshold, the air conditioner is cleaned again until the detected odorous gas concentration is lower than the preset threshold. The internal temperature of the air conditioner is then increased and maintained for 30 minutes for drying. If the odorous gas concentration is lower than the preset threshold, the above drying operation can be performed immediately.

[0043] It is understandable that the detection of odor gas concentration inside the air conditioner is not affected by whether the refrigerant circulation system is running. Instead, the odor gas concentration inside the air conditioner is re-detected after spraying water to determine whether the cleaning components need to be restarted.

[0044] In this embodiment of the application, the preset threshold can be pre-set in the air conditioner by the designer before the air conditioner leaves the factory, and / or the preset threshold can be set by the user according to actual needs, for example, by setting it through a remote control.

[0045] In some technologies, air conditioners use the following methods to remove odors: First, a filter plate made of activated carbon or a heat-desorbable odor absorber is installed at the indoor air outlet to absorb the odorous gases that are to be discharged from the indoor air outlet; Second, negative ions, ozone, and other airflows are used to kill bacteria, mold, and other microorganisms to achieve the effect of purifying and eliminating odors; Third, before the air conditioner starts cooling, heating or electric auxiliary heating is used to kill bacteria, mold, and other microorganisms remaining in the air conditioner's indoor unit's fan wheel, evaporator coils / fins, drip tray, filter, and other components to eliminate odors; Fourth, the compressor displacement is adjusted so that the evaporator temperature is lower than the dew point temperature of the indoor humid air on the surface of the coils / fins, and the dehumidified water is quickly condensed in liquid condensate on the outer surface of the pipe wall, encapsulating and carrying away pollutants and odorous gases; Fifth, for air conditioner indoor units with a fresh air system, the fresh air system is turned on and reversed before cooling to exhaust the odors of the air conditioner indoor unit to the outside, or fresh air treated from outside is directly sent into the room to dilute the odors. Of the three methods for removing odors, the first and second methods, as the adsorption capacity of functional materials such as filters, adsorbents, and purifiers reaches saturation or their performance declines, still result in odors being emitted from the indoor unit of the air conditioner. The deposited pollutants and mold that produce the odor remain attached to the components of the indoor unit, and these deposits continue to increase over time, exacerbating the odor under suitable conditions. The third method, although using high temperatures to kill bacteria, mold, and other microorganisms within the deposited pollutants and reduce odor, does not remove the dust, lint, dander, and other suspended matter adsorbed and deposited on or within the crevices of components such as the fan wheel, evaporator coils / fins, drip tray, and filter screen of the indoor unit. During use, air conditioners quickly absorb and nourish new bacteria, mold, and other microorganisms. Fourthly, small amounts of fresh dust, lint, dander, and other suspended matter, as well as bacteria and mold, adsorb and deposit on the surfaces of components such as the indoor unit's fan wheel, evaporator coil / fins, drip tray, and filter. These are easily discharged outdoors with the condensate. However, residual deposits and bacteria in the crevices are difficult to remove with the condensate. Moreover, when the air conditioner has not been used for a long time, the deposits and bacteria will be more numerous and have stronger adhesion, making it difficult to clean them by the weight of the condensate falling into the drip tray. Fifthly, the fresh air system can only alleviate odors before the air conditioner starts cooling; the deposits and bacteria that cause odors remain.

[0046] The odor control method of this application embodiment can remove odors from the air conditioner in a timely and relatively thorough manner, and has a good degree of intelligence, eliminating the need for users to frequently maintain the air conditioner and improving the convenience of subsequent maintenance of the air conditioner.

[0047] In some embodiments, step S20 further includes: allowing the cleaning component to stand for a second preset time after spraying water into the air conditioner. The second preset time may refer to the time interval between detecting the odor gas concentration again after the water spraying is completed.

[0048] As can be seen, during the cleaning process, the cleaning component first sprays cleaning agent into the air conditioner. After a first preset time, this allows the cleaning agent to fully contact and saturate the cleaning area, maximizing its effectiveness. Then, water is sprayed into the air conditioner. After water spraying, the unit is left to stand for a second preset time (for example, during this time, dirt rinsed away by the water can be expelled from the air conditioner). This allows for a more accurate reflection of the true odor gas concentration inside the air conditioner when the odor gas concentration is detected again, improving detection accuracy. The initial odor gas concentration detected inside the air conditioner serves as the basis for deciding whether to restart the cleaning component, ensuring that the detected value reflects the true odor gas concentration inside the air conditioner, reducing unnecessary resource waste caused by over-cleaning, and thus lowering maintenance costs.

[0049] For example, if the concentration of odorous gas detected reaches a preset threshold and the refrigerant circulation system of the air conditioner is in a closed state, the cleaning component is turned on to clean the air conditioner. The cleaning component first sprays cleaning agent into the air conditioner for 1 minute, and after spraying the cleaning agent, it stands for 10 minutes. Then, it sprays water into the air conditioner for 2 minutes, and after spraying the water, it stands for 10 minutes to allow the pure water to fully wash away the contaminants soaked in the cleaning solution and flow out of the air conditioner from the water tray. The odor concentration in the air conditioner is detected again. If the odorous gas concentration reaches the preset threshold, the air conditioner is cleaned again until the detected odorous gas concentration is lower than the preset threshold. The internal temperature of the air conditioner is then increased and maintained for 30 minutes for drying. If the odorous gas concentration is lower than the preset threshold, the above drying operation can be performed directly.

[0050] Of course, in other embodiments, after spraying water into the air conditioner in step S20, there is no need to let it stand for a second preset time. Other subsequent operations can be performed immediately after the water spraying is finished, such as repeating step S10.

[0051] In some embodiments, step S20 further includes: determining the cleaning level of the cleaning component based on the degree to which the odor gas concentration exceeds a preset threshold and preset data. The cleaning component has multiple cleaning levels, and the cleaning parameters of the multiple cleaning levels are different. The cleaning parameters include at least one of the spraying time of the cleaning agent, a first preset time, and the spraying time of water.

[0052] As can be seen, by measuring the concentration of odorous gases and determining the cleaning level based on how much the concentration exceeds a preset threshold, different cleaning levels correspond to different cleaning parameters, and different cleaning parameters correspond to different cleaning effects or degrees of cleaning, making the cleaning more targeted. The setting of multiple cleaning levels allows the cleaning process to be flexibly adjusted according to the degree of pollution inside the air conditioner. For example, based on the degree to which the odorous gas concentration exceeds a preset threshold, the degree of pollution inside the air conditioner can be determined. The greater the degree of pollution, the higher the corresponding cleaning level can be selected to clean the air conditioner, while the less polluted the degree, the lower the corresponding cleaning level can be selected. This ensures that the cleaning effect achievable by the cleaning components is well matched with the degree of pollution in the air conditioner, meeting the air conditioner cleaning needs while saving cleaning resources and energy consumption, thus improving the system's adaptability and flexibility.

[0053] It is understood that the cleaning parameters include one of the spraying time of the cleaning agent, the first preset time, and the spraying time of the water; or, the cleaning parameters include multiple of the spraying time of the cleaning agent, the first preset time, and the spraying time of the water; or, the cleaning parameters include all of the spraying time of the cleaning agent, the first preset time, and the spraying time of the water. By adjusting the cleaning parameters, the cleaning process can be made more efficient.

[0054] In some embodiments, in step S20, the interval corresponding to the detection result of odor gas concentration reaching a preset threshold is divided into multiple sub-intervals. These sub-intervals include a first sub-interval to an Nth sub-interval. From the first sub-interval to the Nth sub-interval, the degree to which the detection result of odor gas concentration exceeds the preset threshold increases, the corresponding cleaning level increases, and the corresponding cleaning parameters increase. Therefore, by subdividing the intervals, the corresponding cleaning level and parameters can be matched more accurately according to the concentration of odor gas, thereby achieving a rapid and accurate response to different levels of pollution and reducing the possibility of over-cleaning and resource waste.

[0055] For example, when N is set to 3 and the preset threshold is set to 1 mg / m³ 3 When the odor gas concentration reaches a preset threshold, the interval can be subdivided into three sub-intervals, and corresponding cleaning levels and parameters can be set for each sub-interval. First sub-interval: 1 mg / m³ 3 Odor gas concentration <2mg / m³ 3 Cleaning level: Level 1 (light cleaning); Second sub-range: 2 mg / m³ 3 Odor gas concentration <3mg / m³ 3 The cleaning level is Level 2 (medium cleaning); the third sub-zone has an odor gas concentration ≥3mg / m³. 3The cleaning level is 3 (heavy cleaning). As the detection value of the odor gas concentration increases, the corresponding cleaning level increases, and the cleaning parameters also change accordingly. That is, as the cleaning level increases, at least one of the following is increased: the spraying time of the cleaning agent, the spraying time of the water, the settling time after spraying the cleaning agent, and the time between re-detecting the odor gas concentration after spraying the water. This reduces the odor gas concentration in the air conditioner to below the threshold. Appropriate cleaning level and parameters can effectively remove odor gases while avoiding unnecessary wear or damage to the equipment, which helps to extend the service life of the equipment and reduce maintenance costs.

[0056] Of course, the values ​​of N and preset thresholds can be flexibly adjusted according to actual usage to meet the cleaning needs of different scenarios. For example, the N value and preset thresholds can be automatically adjusted based on the air conditioner's usage environment, real-time monitoring data of odor gases, and user feedback to achieve the best cleaning effect.

[0057] In some embodiments, the preset data includes at least one of the following: a table indicating the relationship between odor gas concentration and cleaning parameters; historical operating data of the air conditioner; historical operating parameters of multiple air conditioners of the same model as the air conditioner; and experimental test data of an air conditioner prototype of the same model as the air conditioner.

[0058] Condition 1: A table indicating the relationship between odor gas concentration and cleaning parameters. This table provides direct guidance for the cleaning operation. Based on experimental data or experience, it matches odor gas concentration with corresponding cleaning parameters. By looking up the corresponding cleaning parameter in the table based on the currently detected odor gas concentration, the cleaning operation can be quickly executed. This not only improves cleaning efficiency but also ensures consistent cleaning results.

[0059] Condition 2: Historical operating data of the air conditioner. Analyzing historical operating data allows us to understand the air conditioner's usage frequency, operating time, and performance under different environments. This data helps identify potential sources of odor and cleaning needs, enabling the development of more targeted cleaning strategies. Furthermore, historical data can be used to evaluate the effectiveness of cleaning operations, allowing for continuous optimization of cleaning parameters and processes.

[0060] Condition 3: Historical operating parameters of multiple air conditioners of the same model as the air conditioner. Historical operating parameters of multiple air conditioners of the same model provide a wider range of data, which helps to identify common problems and performance characteristics of the air conditioner of that model. This data can be used to develop a general cleaning strategy applicable to the air conditioner of that model, reducing inconsistencies in cleaning results caused by individual differences.

[0061] Condition 4: Experimental test data of an air conditioner prototype with the same model as the air conditioner. The experimental test data not only covers the cleaning effect under normal conditions, but also includes test results under extreme conditions. This helps to comprehensively evaluate the performance of the cleaning strategy in different environments, ensuring that the cleaning effect can meet expectations under various conditions. By understanding the performance of the cleaning strategy under extreme conditions, the strategy can be adjusted to adapt to a wider range of environmental conditions, ensuring that the cleaning effect remains stable under various circumstances.

[0062] In some embodiments, in step S20, the indoor air outlet of the air conditioner is closed. It can be seen that closing the indoor air outlet of the air conditioner in step S20 can effectively reduce the possibility of cleaning agents, moisture, or other possible pollutants being sprayed out through the air outlet during the cleaning process, thereby reducing secondary pollution to the indoor environment. At the same time, it can also create a relatively closed cleaning environment inside the air conditioner, allowing the cleaning agent to act more effectively inside the air conditioner and improve the cleaning effect.

[0063] In some embodiments, in step S40, the indoor air outlet of the air conditioner is opened and the indoor fan of the air conditioner is rotated. The opening of the indoor air outlet and the rotation of the indoor fan can accelerate the air flow and form a convection effect, so that the hot air flows through the interior of the air conditioner more quickly, thereby accelerating the drying process.

[0064] As can be seen, in step S20, the indoor air outlet of the air conditioner is closed, while in step S40, the indoor air outlet of the air conditioner is opened and the indoor fan rotates, so that the corresponding components of the air conditioner can cooperate with the cleaning and drying process of the air conditioner. This does not affect the cleaning of the air conditioner, but also helps to speed up the removal of odors inside the air conditioner.

[0065] In some embodiments, the odor control method further includes: step S50, if the detected odor gas concentration does not reach a preset threshold and the refrigerant circulation system of the air conditioner is in a closed state, determining whether to turn on the cleaning component based on environmental parameters, or turning on the cleaning component every third preset time interval, or reminding the user to manually turn on the cleaning component based on at least one of the environmental parameters and the time interval from the last cleaning.

[0066] Optionally, the third preset duration can be a parameter preset in the air conditioner before it leaves the factory, or the third preset duration can be a cleaning cycle set by the user via remote control. It can automatically start the cleaning component when the "detected odor gas concentration does not reach the preset threshold and the refrigerant circulation system is in the off state" to achieve regular cleaning. Regular automatic cleaning can solve the problem that pollutants still adhere and deposit inside the air conditioner even when there is no odor gas or very little odor gas is produced. The deposited pollutants may have relatively weak adhesion and are relatively easy to remove, so that when the odor gas concentration exceeds the preset threshold, it is beneficial to improve the thorough cleaning effect.

[0067] As can be seen, if the detected odor gas concentration does not reach the preset threshold and the air conditioner's refrigerant circulation system is in a closed state, the system can determine whether to activate the cleaning component based on environmental parameters. By analyzing environmental parameters in real time, such as weather and / or indoor pollution conditions, the system can intelligently determine whether the cleaning component needs to be activated, effectively reducing unnecessary energy consumption. At the same time, it ensures that the cleaning component can respond promptly when environmental conditions do require it.

[0068] If the detected odor gas concentration does not reach the preset threshold and the air conditioner's refrigerant circulation system is in a closed state, the cleaning component will be activated every third preset time interval. Setting a fixed time interval to activate the cleaning component can ensure that the air conditioner's interior is regularly cleaned and maintained, preventing odors and bacterial growth. For users, this simplifies the operation process, eliminating the need for frequent manual intervention or judgment based on complex environmental parameters.

[0069] If the detected odor gas concentration does not reach the preset threshold and the air conditioner's refrigerant circulation system is in a closed state, the system will remind the user to manually turn on the cleaning components based on at least one of the environmental parameters and the time interval since the last cleaning. The system can provide more personalized reminders to meet the different needs of different users. Users can flexibly perform subsequent corresponding operations according to the reminders and their own needs.

[0070] Obviously, when environmental temperature and humidity conditions are not suitable for the large-scale reproduction of bacteria, mold, and other microorganisms, very little odor gas is produced, resulting in an odor gas concentration that is usually below a preset threshold. In this case, the cleaning components will not be automatically triggered. However, a large amount of pollutants may have already adhered and deposited on the surfaces or in the gaps of components inside the air conditioner, such as the indoor fan, evaporator coil / fins, drip tray, and filter. Over time, more and more pollutants will adhere and deposit inside the air conditioner. When the temperature and humidity conditions reach a level suitable for microbial reproduction, the bacteria, mold, and other microorganisms carried in the pollutants will multiply rapidly and release more odor gas quickly. The setting of step S50 in the above-mentioned solution of this application can adapt to the above situation, improve the applicability of the method, make the cleaning more intelligent, and improve the situation where pollutants inside the air conditioner are blown into the room during the operation of the air conditioner, thus affecting human health.

[0071] For example, step S50 can enable regular cleaning of the air conditioner. Based on environmental parameters such as weather and indoor pollution levels, the system can remind the user to turn on the cleaning component. The user can manually activate the cleaning component at any time via remote control. For instance, a regular cleaning mode can be set via remote control, automatically activating the cleaning system at a set time or triggering a warning reminder. The regular cleaning cycle can be set by the user based on weather or indoor pollution levels; for example, cleaning once a week or two for heavily polluted areas, and once a month or two for lightly polluted areas. This mode effectively avoids the problem of ineffective or difficult cleaning of the surfaces or crevices of the air conditioner's indoor unit components due to the large accumulation of pollutants in heavily polluted environments. Of course, in other examples, the user can also determine whether to activate the cleaning component based on environmental parameters such as weather and indoor pollution levels.

[0072] In some embodiments, such as Figure 2 As shown, the odor control method also includes: step S60, if the detected odor gas concentration does not reach the preset threshold, when the refrigerant circulation system of the air conditioner is turned on in cooling mode, the air conditioner first runs in dehumidification mode for a fourth preset time before entering cooling mode. For example, when the air conditioner is turned on in cooling mode, it first runs in dehumidification mode for 30 minutes.

[0073] It is evident that the odor gas parameters did not reach the preset threshold, indicating that the amount of residual microorganisms inside the air conditioner is low or the temperature and humidity environment is not suitable for microbial proliferation. The adhesion of deposited pollutants may be relatively weak and easier to remove. When the air conditioner needs to run in cooling mode, by first running the dehumidification mode and then switching to cooling mode, the pollutants and bacteria can be expelled from the air conditioner by encapsulating them with condensate. This can effectively reduce the continuous adhesion and deposition of pollutants and bacteria, preventing excessive accumulation that makes cleaning difficult. It also minimizes the adsorption and deposition of suspended matter such as dust, lint, and dander on the surfaces or crevices of components such as the fan wheel, evaporator coils / fins, drip tray, and filter, thus preventing the rapid reproduction of bacteria, mold, and other microorganisms under conditions of sufficient moisture and suitable temperature. Moreover, under normal circumstances, the dehumidification mode produces more condensate than the cooling mode, making it easier to encapsulate and expel the small amount of residual pollutants and bacteria from the surfaces and crevices of the air conditioner's internal components to the outside. In addition, the indoor fan speed is fixed and relatively gentle in dehumidification mode, resulting in almost no draft indoors, and the small amount of residual pollutants is less likely to be blown into the room, thereby improving the user experience.

[0074] In some embodiments, such as Figure 2As shown, the odor control method also includes: step S70, if the detected odor gas concentration reaches a preset threshold and the air conditioner's refrigerant circulation system is on, outputting a prompt message to remind the user that the odor gas concentration exceeds the standard. Through this timely prompt, the user can quickly understand that the odor gas concentration has exceeded the standard, thus facilitating immediate action based on their needs. For example, the user can turn off the air conditioner's refrigerant circulation system, simultaneously close the air conditioner's indoor air outlet, and activate the cleaning component to clean the air conditioner. During the cleaning process, the cleaning component first sprays cleaning agent into the air conditioner, and after a first preset time, allows... The cleaning agent is fully applied to and soaks the parts to be cleaned. Then, water is sprayed into the air conditioner. The water spray can wash away the dirt and cleaning agent from the various parts inside the air conditioner. After spraying water, the air conditioner is left to stand for a second preset time. The concentration of odor gas inside the air conditioner is then detected again. If the concentration of odor gas still reaches the preset threshold, the air conditioner is cleaned again until the detected concentration of odor gas is lower than the preset threshold. After cleaning the air conditioner at least once, if the detected concentration of odor gas is lower than the preset threshold, the indoor air outlet of the air conditioner is opened and the indoor fan of the air conditioner is turned on. At the same time, the internal temperature of the air conditioner is increased to dry it and quickly eliminate the odor.

[0075] It is understood that the output of the prompt message to remind the user that the odor gas concentration exceeds the standard can be displayed on the air conditioner's display panel (the display panel can be the main control display panel of the air conditioner or another display panel independent of the main control display panel) or remote control, displaying an odor gas concentration parameter indicator or displaying the detected odor gas concentration. For example, the odor gas is displayed on the air conditioner's display panel, and the odor gas concentration parameter indicator uses a red LED to indicate that it exceeds a preset threshold and a green LED to indicate that it is below the preset threshold. Alternatively, the air conditioning system can be connected to the user's smartphone. When the odor gas concentration is detected to exceed the preset threshold, the air conditioning system sends a prompt message to the user through a smartphone application, thereby keeping the air conditioner clean. Of course, in other embodiments, the prompt message to remind the user that the odor gas concentration exceeds the standard can also include sound information, so that the user can know that the current odor gas concentration has reached the preset threshold after hearing the sound information.

[0076] like Figure 2As shown, in some embodiments, the odor control method is used for an air conditioner, and the odor control method includes: steps S10-S70, step S10: detecting the concentration of odor gas inside the air conditioner and the operating status of the air conditioner's refrigerant circulation system; step S20: if the detected odor gas concentration reaches a preset threshold and the air conditioner's refrigerant circulation system is in a closed state, then turning on the cleaning component, the cleaning component sprays cleaning agent into the air conditioner, and after a first preset time, sprays water into the air conditioner; step S30: repeating steps S10 and S20 until the detected odor gas concentration is lower than the preset threshold; step S40: raising the internal temperature of the air conditioner for drying.

[0077] Step S20 further includes: determining the cleaning level of the cleaning component based on the degree to which the odor gas concentration exceeds a preset threshold and preset data. The cleaning component has multiple cleaning levels, and the cleaning parameters for each level are different. The cleaning parameters include at least one of the spraying time of the cleaning agent, a first preset time, and the spraying time of water. In step S20, the interval corresponding to the odor gas concentration reaching the preset threshold is divided into multiple sub-intervals, including a first sub-interval to an Nth sub-interval. From the first sub-interval to the Nth sub-interval, the degree to which the odor gas concentration exceeds the preset threshold increases, the corresponding cleaning level increases, and the corresponding cleaning parameters increase.

[0078] In step S20, the indoor air outlet of the air conditioner is closed; in step S40, the indoor air outlet of the air conditioner is opened, and the indoor fan of the air conditioner rotates.

[0079] Step S50: If the detected odor gas concentration does not reach the preset threshold and the refrigerant circulation system of the air conditioner is in a closed state, determine whether to turn on the cleaning component based on environmental parameters, or turn on the cleaning component every third preset time interval, or remind the user to manually turn on the cleaning component based on at least one of the environmental parameters and the time interval from the last cleaning.

[0080] Step S60: If the detected odor gas concentration does not reach the preset threshold, when the refrigerant circulation system of the air conditioner is turned on in cooling mode, the air conditioner will first run in dehumidification mode for a fourth preset time before entering cooling mode.

[0081] Step S70: If the detected odor gas concentration reaches a preset threshold and the refrigerant circulation system of the air conditioner is in the open state, output a prompt message to remind the user that the odor gas concentration exceeds the standard.

[0082] As can be seen, the odor control method of this invention includes: automatically detecting the concentration of odorous gases inside the air conditioner and intelligently performing closed-loop cleaning and preventing the generation of odor concentration inside the air conditioner, and has the following technical features:

[0083] First, it can automatically detect the concentration of odor gases inside the air conditioner and perform intelligent closed-loop cleaning.

[0084] In some technologies, regardless of whether the air conditioner is running, suspended particles such as dust, lint, and dander in the air will constantly come into direct contact with components inside the air conditioner, such as the fan, evaporator coils / fins, drip tray, and filter, and will adhere and accumulate on their surfaces or in their crevices, creating an environment that nourishes bacteria, mold, and other microorganisms. Over time, these bacteria and mold will proliferate and metabolize under suitable humidity and temperature conditions, producing odorous organic byproducts. Furthermore, components such as the fan, evaporator coils / fins, drip tray, and filter in the indoor unit of the air conditioner are enclosed by the air conditioner casing, making it impossible to visually inspect the formation of pollutants and microbial deposits. These can only be smelled when the odor is strong enough. However, when an odor can be detected by smell, it indicates that pollutants and microbial deposits have accumulated to a severe degree on these components, requiring specialized cleaning to remove the pollutants and microbial deposits and eliminate the odor. In some technologies, air conditioner odor control methods mainly target the odor gas itself, using filters, adsorbents, or other media to adsorb it, or dilute it with fresh outdoor air, or encapsulate it with condensate water to discharge it, or directly kill bacteria, mold and other microorganisms to reduce or lower the concentration of odor gas. However, the source of the odor is not completely eliminated, and the pollutants that nourish bacteria, mold and other microorganisms still adhere to and deposit on the surface and in the gaps of the indoor unit components of the air conditioner.

[0085] Therefore, the odor control method in the above embodiments can detect the concentration of odor gas inside the air conditioner in real time, regardless of whether the refrigerant circulation system of the air conditioner is in a closed state or an on-running state. By comparing with a preset threshold, it can determine whether to immediately turn on the cleaning component to clean the inside of the air conditioner or to turn on the cleaning component periodically to clean the inside of the air conditioner. This can reduce the large amount of pollutants adhering and depositing on the surface and in the gaps of the indoor unit components of the air conditioner, making the cleaning of pollutants more convenient.

[0086] When the detected odor gas concentration exceeds a preset threshold, and the air conditioner's refrigerant circulation system is off, the air conditioner automatically activates its cleaning component to perform cleaning. During the cleaning process, the odor gas concentration is monitored in real time to determine if the cleanliness inside the air conditioner meets the standard. If it is below the preset threshold, the standard is met; if it is above the preset threshold, the cleaning process is repeated until the cleanliness inside the air conditioner meets the standard. When the detected odor gas concentration is below the set threshold, and the air conditioner's refrigerant circulation system is off, the air conditioner periodically activates its cleaning component to clean the inside of the air conditioner. Users can set the cleaning cycle according to the environmental pollution level, which can effectively prevent pollutants from adhering to the surfaces and crevices of the air conditioner's internal components.

[0087] This method of automatically detecting the concentration of odorous gases inside the air conditioner and intelligently performing closed-loop cleaning can reduce the amount of pollutants adhering and depositing on the surface and in the gaps of the indoor unit components, thereby improving the cleanliness of the air conditioner.

[0088] Second, prevent the formation of odor concentration inside the air conditioner.

[0089] When the detected odor gas concentration is below a preset threshold, the air conditioner periodically activates the cleaning component to clean its internal components, regularly removing adhering contaminants to reduce their accumulation on the surfaces and in the crevices of these components. Additionally, when cooling is required, the air conditioner first runs in dehumidification mode for a fourth preset duration. This allows condensate to coat the surfaces and crevices of components such as the fan, evaporator coils / fins, drip tray, and filter, causing small amounts of contaminants to fall into the drip tray and be discharged from the air conditioner. This mode effectively removes small amounts of contaminants and bacteria adhering to the surfaces and crevices of these components. These small amounts of contaminants and bacteria are not firmly deposited and are easily cleaned, preventing their accumulation and hardening during prolonged use. Therefore, periodically activating the cleaning component and using dehumidification mode to remove small amounts of contaminants when the odor gas concentration is below the preset threshold is an effective measure for preventing odors.

[0090] Therefore, the odor control method of this invention has the beneficial effects of high degree of intelligent automation, closed-loop operation, and autonomous prevention of odor generation. Furthermore, the odor control method of this application has the following advantages: 1. It automatically detects the concentration of odor gases inside the air conditioner and determines whether the detected concentration exceeds a preset threshold. Simultaneously, it detects whether the refrigerant circulation system of the air conditioner is in a closed state, thereby intelligently controlling the operation of the air conditioner cleaning components. This has a very high level of automation and intelligence, reducing manual operation and improving cleaning efficiency; 2. By detecting and cleaning before a large amount of odor is generated, pollutants will not accumulate in large quantities on the surface or in the gaps of components such as the fan wheel, evaporator coil / fins, drip tray, and filter inside the air conditioner for a long time. 3. Preventing the generation of odor concentration inside the air conditioner: If the odor gas concentration is detected to be lower than the preset threshold, the air conditioner will periodically turn on the cleaning component to effectively reduce the accumulation of pollutants on the surface or in the gaps of the air conditioner's internal components. In addition, if the odor gas concentration is not detected to reach the preset threshold at this time, it indicates that the amount of pollutants remaining on the internal components of the air conditioner is small and the degree of pollution is low. When the air conditioner is turned on for cooling, it will first run in dehumidification mode for the fourth preset time. Under the gentle airflow, the dehumidification mode will use more condensate to clean the dust, lint, dander and other pollutants and bacteria adsorbed and deposited on the surface or in the gaps of the fan wheel, evaporator coil / fins, water tray, filter and other components. The pollutants will be discharged through the condensate, which effectively improves the cleanliness of the air conditioner.

[0091] According to a second aspect embodiment of the present invention, an odor removal device 100 is used in an air conditioner 200, such as... Figure 3 As shown, the odor removal device 100 includes: a first detection component 10, a second detection component 20, a cleaning component 30, a heating component 40, and a control component 50.

[0092] The first detection component 10 detects the concentration of odorous gases inside the air conditioner 200, providing basic data for the operation of the cleaning component 30 and the heating component 40. The second detection component 20 detects the operating status of the refrigerant circulation system of the air conditioner 200, effectively reducing the possibility of the cleaning component 30 starting erroneously. The cleaning component 30 includes a first liquid storage structure 32, a second liquid storage structure 34, a valve structure 36, and a nozzle 38. The first liquid storage structure 32 and the second liquid storage structure 34 are used to hold cleaning agent and water, respectively, allowing the cleaning process to select either cleaning agent or water as needed. The valve structure 36 controls the flow between the first liquid storage structure 32 and the nozzle 38, as well as between the second liquid storage structure 34 and the nozzle 38. The valve structure 36 allows for precise control of the flow of cleaning agent and water, avoiding unnecessary waste. The heating component 40 heats the interior of the air conditioner 200, accelerating the evaporation and diffusion of the cleaning agent or water, and improving the cleaning effect. The control component 50 communicates with the first detection component 10, the second detection component 20, the valve structure 36, and the heating component 40 respectively. The control component 50 controls the valve structure 36 and the heating component 40 according to the detection results of the first detection component 10 and the second detection component 20. Thus, the control component 50 can automatically decide whether to start the cleaning component 30 and the heating component 40 based on the detection results of the first detection component 10 and the second detection component 20. This intelligent control method can improve the efficiency of the odor removal device 100 and the user experience.

[0093] According to an embodiment of the present invention, the odor removal device 100 achieves efficient, intelligent and environmentally friendly treatment of odors inside the air conditioner 200 through the coordinated operation of the first detection component 10, the second detection component 20, the cleaning component 30, the heating component 40 and the control component 50, providing users with a fresher and more comfortable indoor environment.

[0094] For example, the first liquid storage structure 32 is used to hold cleaning agent, and the second liquid storage structure 34 is used to hold water. The detection results of the first detection component 10 and the second detection component 20 can be transmitted to the control component 50. The control component 50 can make a judgment based on the above detection structures. If the detection result of the first detection component 10 reaches a preset threshold, and the detection result of the second detection component 20 indicates that the refrigerant circulation system is in a closed state, then the control component 50 controls the cleaning component 30 to open, so that the valve structure 36 controls the connection between the first liquid storage structure 32 and the nozzle 38, and controls the disconnection between the second liquid storage structure 34 and the nozzle 38. The cleaning component 30 sprays cleaning agent into the air conditioner 200. After spraying and standing for a first preset time, the valve structure 36 controls the disconnection between the first liquid storage structure 32 and the nozzle 38, and controls the connection between the second liquid storage structure 34 and the nozzle 38, so that the cleaning component 30 sprays water into the air conditioner 200. After spraying water, it stands for a second preset time. The concentration of odor gas is repeatedly detected. As long as the concentration of odor gas reaches a preset threshold, the cleaning component 30 cleans the air conditioner 200 until the concentration of odor gas is lower than the preset threshold. Then, the control component 50 controls the heating component 40 to heat the inside of the air conditioner 200.

[0095] It is understood that in the embodiments of this application, the heating component 400 may include an electric auxiliary heating component disposed in the air conditioner 200, and / or a heat exchanger, such as an indoor heat exchanger, that serves as a condenser in the air conditioner 200.

[0096] In some embodiments, the valve structure 36 includes a first valve and a second valve. The first valve is located on the outlet side of the first liquid storage structure 32, and the second valve is located on the outlet side of the second liquid storage structure 34. Both the first valve and the second valve are electrically controlled valves. The control component 50 can control the opening and closing of the electrically controlled valves to realize the disconnection and connection between the first liquid storage structure 32 and the nozzle 38, and between the second liquid storage structure 34 and the nozzle 38. The electrically controlled valves can respond quickly and adjust their opening and closing states to realize the switching of disconnection and connection states between different liquid storage structures and the nozzle 38, thereby improving the automation level of the cleaning component 30 during operation.

[0097] Optionally, the electrically controlled valve is a normally closed valve. The electrically controlled valve is connected to the control component 50 via a wire so that the control component 50 can supply power and control its opening and closing. The electrically controlled valve can be an electromagnetically controlled valve. The fast response characteristics of the electromagnetically controlled valve reduce the delay and error in the opening and closing of the valve structure 36, thereby improving the cleaning efficiency of the cleaning component 30.

[0098] In other embodiments of this application, such as Figure 3As shown, the odor removal device 100 also includes a third detection component 60, which communicates with the control component 50 and is used to detect the environmental parameters of the air conditioner 200. The control component 50 controls the cleaning component 30 based on the detection results of the third detection component 60. The third detection component 60 transmits the detection results to the control component 50 through real-time analysis of the environmental parameters. The control component 50 determines whether to start the cleaning component 30 based on the detection results when the detected odor gas concentration has not reached the preset threshold and the refrigerant circulation system is in a closed state. This enables the system to intelligently determine whether the cleaning component 30 needs to be started, effectively reducing unnecessary energy consumption and facilitating intelligent adjustment in seasons or regions with high humidity or poor air quality.

[0099] In some embodiments of this application, the cleaning assembly 30 further includes a water pump 37, and the valve structure 36 is connected to the nozzle 38 via the water pump 37. The water pump 37 is used to provide water flow power to the nozzle 38. The water pump 37 makes it easier to spray cleaning agent or water onto the parts inside the air conditioner 200 that need to be cleaned.

[0100] Optionally, the water pump 37 is connected to the control component 50 via a wire. If the water pump 37 is an electrically controlled mechanical pump, the control component 50 can precisely control the working state of the water pump 37, allowing the cleaning process to be flexibly adjusted according to actual needs, which helps to improve cleaning efficiency and avoid unnecessary energy waste. Of course, the water pump 37 can also be an electrically controlled silent water pump, in which case the user can precisely control the working state of the water pump 37 through the control component 50, while providing the user with a more efficient, quiet and convenient user experience.

[0101] In some embodiments, the control component 50 determines the cleaning level of the cleaning component 30 based on the degree to which the concentration of odor gas detected by the first detection component 10 exceeds a preset threshold and preset data, and the control component 50 is used to adjust the cleaning parameters of different cleaning levels.

[0102] According to a third aspect embodiment of the present invention, the air conditioner 200 has a refrigerant circulation system, which includes a compressor, a commutator, an indoor heat exchanger 80, an outdoor heat exchanger, and a throttling element. The air conditioner 200 can achieve cooling and heating modes through the refrigerant circulation system. The air conditioner 200 also includes a housing, a drip tray 70, an electrical control box, and an odor removal device 100 according to a second aspect embodiment of the present invention. The indoor heat exchanger 80, the drip tray 70, the first detection component 10, the nozzle 38, and the heating component 40 are all disposed within the housing. The drip tray 70 is located below the indoor heat exchanger 80 and has a drain outlet. The control component 50 communicates with the electrical control box. Therefore, by employing the aforementioned odor removal device 100, it is convenient to maintain the cleanliness of the air conditioner 200 and remove odors from inside the air conditioner 200.

[0103] It is understood that the type of air conditioner 200 in this application embodiment is not limited. It can be a vehicle air conditioner, an integrated air conditioner, or a split air conditioner. An integrated air conditioner can include a window air conditioner or a portable air conditioner, etc., while a split air conditioner can include a wall-mounted air conditioner or a floor-standing air conditioner, etc. When the air conditioner 200 is a split air conditioner, the odor control method and the odor removal device 100 can be used for cleaning the indoor unit of the air conditioner. For example, the cleaning component 30 can clean the deposits or bacteria adhering to the surface or crevices of components such as the fan wheel, evaporator coil / fins, drip tray, and filter of the indoor unit of the air conditioner.

[0104] For example, the control box can be used as the main control module of the air conditioner 200. The control component 50 can be embedded in the control box, or it can be set apart from the control box and connected to the control box through wires. Based on the detected odor gas concentration data, control information is generated to regulate the working status of the intelligent cleaning component. The control information is sent to the control box and displayed on the panel.

[0105] In some embodiments, such as Figure 4 As shown, the detection head of the first detection component 10 is spaced between the indoor heat exchanger 80 and the water collection tray 70, and is located near the drain outlet. The drain outlet is the area inside the air conditioner 200 most prone to accumulating dirt and bacteria; the air quality in the vicinity often best reflects the overall level of dirt inside the air conditioner 200. Positioning the detection head near the drain outlet ensures that the first detection component 10 can accurately detect odorous gases in this area, providing more precise detection data. This allows the air conditioning system to promptly activate the cleaning mode, thus maintaining the cleanliness inside the air conditioner 200. Optionally, the first detection component 10 can be located below the indoor heat exchanger and fixed to the inner wall of the air conditioner's outer casing by a supporting and protective structure.

[0106] In some embodiments, the first detection component 10 is a gas sensor. The gas sensor can accurately measure the concentration of odor gas in the air conditioner 200, providing precise detection data to the control component 50. This allows the control component 50 to accurately obtain the concentration of odor gas inside the air conditioner 200 and take appropriate cleaning measures, thereby improving the reliability of the air conditioner 200. Optionally, the first detection component 10 can be a semiconductor gas sensor, an electrochemical gas sensor, or an optical gas sensor, etc., which the user can select according to actual needs.

[0107] In some embodiments, the first detection component 10, the second detection component 20, the third detection component 60, the cleaning component 30, and the heating component 40 communicate with the control component 50 via wires, thereby improving the stability and reliability of data transmission between the components.

[0108] Optionally, the conductor is a high-waterproof conductor with excellent waterproof performance. This type of conductor can effectively reduce the possibility of moisture penetrating into the conductor, thereby reducing the risk of electrical faults such as short circuits and open circuits, and improving the stability of the air conditioner 200 operation.

[0109] In some embodiments, at least one of the first liquid storage structure 32 and the second liquid storage structure 34 is detachably disposed outside the housing. When the first liquid storage structure 32 or the second liquid storage structure 34 needs to be cleaned, replenished, repaired or replaced, due to its detachable design and its location outside the housing, the user can easily remove it from the housing without disassembling the housing and other internal components, thus simplifying the maintenance process.

[0110] like Figures 5-7 As shown, in some embodiments, the air conditioner 200 has a removable filter structure 90 at its air inlet. The odor removal device 100 has a first main channel 92, a second main channel 94, a first branch channel 96, and a second branch channel 98. Both the first branch channel 96 and the second branch channel 98 are connected to one end of the first main channel 92. The end of the first branch channel 96 away from the first main channel 92 is connected to the first liquid storage structure 32. The end of the second branch channel 98 away from the first main channel 92 is connected to the second liquid storage structure 34. The other end of the first main channel 92 is removably connected to the second main channel 94. The nozzles 38 are detachably connected, and multiple nozzles 38 are all located on the second main path 94. The second main path 94 is detachably located on the filter structure 90. The second main path 94 includes multiple first flow paths 940 spaced apart along the length direction of the filter structure 90 and multiple second flow paths 942 spaced apart along the width direction of the filter structure 90. Each first flow path 940 is provided with multiple nozzles 38 spaced apart along the width direction of the filter structure 90, and each second flow path 942 is provided with multiple nozzles 38 spaced apart along the length direction of the filter structure 90.

[0111] As can be seen, one end of the first branch 96 and the second branch 98 are both connected to one end of the first main branch 92. The first liquid storage structure 32 and the second liquid storage structure 34 are used to hold cleaning agent and water, respectively. Therefore, the air conditioner 200 can control the connection or disconnection of the first branch 96 and the first main branch 92, and the connection or disconnection of the second branch 98 and the first main branch 92, as needed. For example, the first liquid storage structure 32 is used to hold cleaning agent, and the second liquid storage structure 34 is used to hold water. When the cleaning component 30 needs to be activated for cleaning, the air conditioner 200 can first connect the first branch 96 to the first main branch 92 and disconnect the second branch 98 from the first main branch 92, so that the nozzle 38 can smoothly... After spraying the cleaning agent, the system is left to stand for a preset time. Then, the air conditioner 200 controls the first branch 96 to disconnect from the first main branch 92, and the second branch 98 to connect to the first main branch 92. This allows the nozzles 38 to spray water smoothly, washing away dirt and cleaning agent from the internal components of the air conditioner 200 and improving its cleanliness. The other end of the first main branch 92 is detachably connected to the second main branch 94 (e.g., the outlet of the first main branch 92 can be plugged into the inlet of the second main branch 94). Multiple nozzles 38 are mounted on the second main branch 94, which is detachably mounted on the filter structure 90. When cleaning the filter structure 90 is required... When cleaning or maintenance or replacement of the nozzle 38 is required, the first main channel 92 and the second main channel 94 can be disconnected, and the filter structure 90 and the second main channel 94 can be disassembled together for easy cleaning of the filter and maintenance of the nozzle 38. The second main channel 94 includes multiple first flow paths 940 spaced apart along the length direction and multiple second flow paths 942 spaced apart along the width direction. Multiple nozzles 38 are spaced apart along the width direction in the first flow path 940, and multiple nozzles 38 are spaced apart along the length direction in the second flow path 942, so that the first flow path 940 and the second flow path 942 form a mesh structure. By spaced the nozzles 38 in different directions, multiple nozzles can be arranged in a mesh-like structure. The nozzles 38 are roughly arranged in an array, ensuring effective coverage of all areas of the second main path 94. Whether in the first flow path 940 or the second flow path 942, the nozzles 38 are arranged at certain intervals, effectively improving the cleaning range and efficiency of the cleaning assembly 30. The air inlet of the air conditioner 200 is equipped with a removable filter structure 90, and the second main path 94 is detachably mounted on the filter structure 90. The multiple nozzles 38 on the second main path 94 can spray cleaning agent or water first onto the indoor heat exchanger 80, and then flow to the impeller area, effectively removing impurities adhering to the indoor heat exchanger 80 and the impeller, thus improving the cleanliness of the air conditioner 200. Alternatively, the nozzles 38 on the second main path 94 can also spray water or cleaning agent first onto the filter structure 90, and then flow sequentially through the indoor heat exchanger 80 and the impeller area, further improving the cleanliness of the filter structure 90 and reducing the frequency of filter structure 90 cleaning.

[0112] like Figure 7 and Figure 8 As shown, in some embodiments, the first flow path 940 is a water pipe, the second flow path 942 is also a water pipe, and the filter structure 90 has multiple clips 99. The cross-section of the clips 99 is a C-shaped structure, and the opening width of the C-shaped clips 99 is smaller than the diameter of the water pipes in the first flow path 940 and the second flow path 942. The opening of the clips 99 has a certain elasticity, so that the width of the opening of the clips 99 is adjustable.

[0113] As can be seen, the C-shaped clamp 99 design, with its opening distance smaller than the diameter of the water pipe (i.e., the first flow path 940 and the second flow path 942), allows the clamp 99 to tightly wrap around the water pipe, forming a stable connection and reducing the possibility of the water pipe falling off during use. Simultaneously, the elastic design of the C-shaped clamp 99 makes disassembly of the water pipe easier. Compared to fixed connections, this design allows workers to easily disassemble the clamp 99 without damaging the water pipe or filter structure 90. Furthermore, although the opening width of the C-shaped clamp 99 is smaller than the diameter of the water pipe, its elastic design allows the clamp 99 to adapt to water pipes of different sizes to a certain extent. This means that in practical applications, the same batch of C-shaped clamps 99 can be used to connect water pipes of different diameters, thereby improving the versatility and flexibility of the clamp 99.

[0114] Optionally, if the water pipe has good flexibility, it can adapt to different shapes of filter structures 90, such as an arc-shaped filter structure 90, which can improve the practicality of the water pipe.

[0115] Optionally, at least one nozzle 38 is rotatably configured so that the at least one nozzle 38 can spray cleaning agent and / or water toward the filter structure 90.

[0116] Optionally, the filter structure 90 includes a filter and a frame. The frame includes a plurality of first ribs spaced apart along the length of the filter structure 90 and a plurality of second ribs spaced apart along the width of the filter structure 90. A plurality of first flow paths 940 correspond one-to-one with the plurality of first ribs, and each first flow path 940 is located on the leeward side of the corresponding first rib. A plurality of second flow paths 942 correspond one-to-one with the plurality of second ribs, and each second flow path 942 is located on the leeward side of the corresponding second rib. This helps to reduce the obstruction effect of the second main path 94 on the airflow and facilitates the improvement of the excessive increase in airflow resistance caused by the setting of the second main path 94.

[0117] like Figure 4As shown, in some embodiments, the nozzle 38 is a spraying device consisting of no fewer than three identical nozzles connected in series. The nozzle 38 is connected to the valve structure 36 via a water pipe. Both ends of the nozzle 38 are fixed to the inner wall of the air conditioner indoor unit casing above the indoor heat exchanger 80. It can rotate and spray in both forward and reverse directions to cover the components inside the air conditioner 200 to the maximum extent, effectively improving the cleaning range and working efficiency of the cleaning assembly 30.

[0118] For example, multiple nozzles 38 are spaced apart along a first direction, and each nozzle 38 oscillates in the same plane around a straight line extending along the first direction. At this time, the nozzle 38 roughly performs a pendulum motion, for example, oscillating forward and backward by a maximum of 30° (e.g., if the first direction is left-right, the nozzle 38 oscillates back and forth; or, if the first direction is front-back, the nozzle 38 oscillates left and right). In some other examples, multiple nozzles 38 are spaced apart along the first direction, and each nozzle 38 performs a conical pendulum motion around a straight line extending along a second direction (e.g., if the first direction is left-right, the second direction is up-down). The second direction is perpendicular to the first direction, and the spray trajectory of the nozzle 38 is circular, thereby expanding the spray range of the nozzle and effectively improving the working efficiency of the cleaning assembly 30.

[0119] In some embodiments, a slide rail is provided on the inner wall of the air conditioner indoor unit casing above the indoor heat exchanger 80. The slide rail includes a first slide rail extending along the length direction of the air conditioner indoor unit casing and a second slide rail extending along the width direction of the air conditioner indoor unit casing. The first slide rail and the second slide rail are arranged vertically, and the nozzle 38 is provided on the first slide rail or the second slide rail.

[0120] For example, the nozzle 38 is mounted on a first slide rail, which moves the nozzle 38 along its length. A second slide rail moves the nozzle 38 along its width by moving the first slide rail, thus increasing the spray range of the nozzle 38 and improving the working efficiency of the cleaning assembly 30. Simultaneously, the nozzle 38 can move freely within the air conditioner's indoor unit casing along both its length and width, allowing for more flexible spraying positions and facilitating spraying onto various components within the air conditioner. Alternatively, the nozzle 38 can be mounted on a second slide rail, which moves the nozzle 38 along its width. The first slide rail moves the nozzle 38 along its length by moving the second slide rail, similarly increasing the spray range.

[0121] In some embodiments, the nozzle 38 is a high-pressure nozzle, and the nozzle of the high-pressure nozzle is selected to spray a spray type, so that the high-pressure nozzle 38 can spray cleaning fluid and pure water evenly over a larger area, reduce spray dead zones, and improve the cleaning range and working efficiency of the cleaning component 30.
