[0032] An embodiment of the present application provides an air conditioner, which includes the air conditioner indoor unit 100 of any embodiment of the present application.
[0033] An air conditioner is a household appliance used to regulate indoor temperature, humidity, and air quality. It is mainly composed of several parts, such as a compressor, a condenser, an evaporator, an indoor unit, and an outdoor unit.
[0034] The present application embodiment provides an air conditioner indoor unit 100, see Figures 1 to 5 The air conditioner indoor unit 100 includes a chassis 1, a drainage assembly 2 and a bubble generating device 3. The chassis 1 is provided with a liquid storage tank 11 and a drainage hole 12. The drainage hole 12 is connected to the liquid storage tank 11. The liquid storage tank 11 can be used to store condensed water from the evaporator of the air conditioner indoor unit 100. The drainage assembly 2 has a drainage channel 21. The drainage channel 21 is connected to the drainage hole 12. The drainage assembly 2 is used to drain the condensed water in the liquid storage tank 11. The drainage assembly 2 includes a switch valve 22. The switch valve 22 is used to selectively open or close the drainage channel 21 and / or the drainage hole 12. The bubble generating device 3 is arranged in the liquid storage tank 11, and is used to act on the condensed water in the liquid storage tank 11 and generate bubbles to clean the liquid storage tank 11.
[0035] The chassis 1 is a structure in the air conditioner indoor unit 100 that supports and houses other components. The specific structure of the chassis 1 is not limited herein. A liquid storage tank 11 and a drain hole 12 are provided on the chassis 1 to provide space for the storage and discharge of condensed water.
[0036] The specific structure of the liquid storage tank 11 is not limited herein. The condensed water generated on the evaporator 4 of the air conditioner indoor unit 100 can be stored in the liquid storage tank 11.
[0037] Exemplarily, in some embodiments, the liquid storage tank 11 may be a groove-shaped structure formed on the chassis 1. In some other embodiments, the chassis 1 may include a seat body and a liquid storage member. A liquid storage tank 11 is formed inside the liquid storage member, and the liquid storage member is assembled on the seat body, that is, the liquid storage member and the seat body are of a split structure.
[0038] In some embodiments, the liquid storage tank 11 is an open groove-shaped structure. The liquid storage tank 11 is arranged below the evaporator 4, and the condensed water generated on the evaporator 4 drips into the liquid storage tank 11 through the opening.
[0039] The drain hole 12 is opened on the chassis 1 and communicates with the liquid storage tank 11, so that the condensed water in the liquid storage tank 11 can be discharged through the drain hole 12. The specific setting position of the drain hole 12 is not limited herein.
[0040] The drain assembly 2 has a drain channel 21, and the drain channel 21 is used to discharge the condensed water in the liquid storage tank 11 to a specific position.
[0041] The switching valve 22 of the drain assembly 2 is used to selectively open or close the drain channel 21 and / or the drain hole 12, which means that the switching valve 22 can control the start or stop of the drainage function of the drain assembly 2 by opening or closing the drain channel 21. The switching valve 22 can also control the start or stop of the drainage function of the drain assembly 2 by opening or closing the drain hole 12. Of course, the switching valve 22 can also control or open the drain channel 21 and the drain hole 12 simultaneously to control the start or stop of the drainage function of the drain assembly 2.
[0042] The switching valve 22 here is a device that can selectively open or close the drain channel 21 and / or the drain hole 12, and is used to control the discharge of condensed water.
[0043] The specific structure of the switching valve 22 is not limited herein. For example, it can be a valve arranged on the drain channel 21 or the drain hole 12, or other throttling structures.
[0044] The bubble generating device 3 is arranged in the liquid storage tank 11 and can act on the condensed water in the liquid storage tank 11 to generate bubbles, so as to realize the function of cleaning the liquid storage tank 11.
[0045] The specific structure of the bubble generating device 3 is not limited herein. In some embodiments, the bubble generating device 3 utilizes a mechanical structure, such as a rotating component or a vibrating device, to cause the condensed water to generate turbulence, thereby mixing air to form bubbles. In other embodiments, the bubble generating device 3 generates energy through an electrical device, such as an ultrasonic generator, etc., to cause physical changes in the condensed water, thereby generating bubbles.
[0046] During the process of the bubbles rising in the condensed water, they will drive the surrounding water flow to move, forming agitation of the water flow. This agitation can keep the condensed water in the liquid storage tank 11 flowing continuously, preventing impurities in the condensed water from precipitating at the bottom of the liquid storage tank 11, thereby keeping the liquid storage tank 11 clean. At the same time, when the bubbles burst, they will release a certain amount of energy, and this energy can have an impact on the inner wall of the liquid storage tank 11, helping to remove dirt and bacteria adhering to the inner wall of the liquid storage tank 11. In addition, in some embodiments, the air in the bubbles can undergo a chemical reaction with certain substances in the condensed water, such as oxidation, thereby decomposing some organic pollutants and further improving the cleaning effect.
[0047] The position of the bubble generating device 3 is not limited herein. After the bubble generating device 3 is installed, it should be able to act with the condensed water to generate bubbles.
[0048] The position and working mode of the bubble generating device 3 should be adapted to the shape and size of the liquid storage tank 11 to ensure that the entire liquid storage tank 11 can be effectively cleaned. For example, if the liquid storage tank 11 is relatively large, multiple bubble generators can be considered to improve the cleaning effect.
[0049] In some embodiments, the size of the bubble generating device 3 should be suitable for installation in the liquid storage tank 11, and at the same time its shape should not affect the storage space and drainage function of the liquid storage tank 11 as much as possible. It may adopt a small cylindrical, spherical or flat shape, etc.
[0050] In some embodiments, the bubble generating device 3 is made of a material that is corrosion-resistant, high-temperature resistant and not easily damaged, so that the bubble generating device 3 can operate stably for a long time under the working environment of the air conditioner indoor unit 100. For example, materials such as stainless steel and plastic can be selected.
[0051] The indoor air conditioner 100 provided by the embodiment of the present application is provided with a liquid storage tank 11 on the chassis 1 for storing the condensed water generated by the evaporator 4. The drainage channel 21 is communicated with the liquid storage tank 11 through a drainage hole 12, so as to realize the orderly discharge of the condensed water, and reduce the damage of other components of the indoor air conditioner 100 caused by the contact of the condensed water with other components of the indoor air conditioner 100. By setting a switching valve 22 to control the opening and closing of the drainage channel 21 and / or the drainage hole 12, in the closed state, the water storage tank can store water. The bubble generating device 3 arranged in the liquid storage tank 11 acts on the stored condensed water to generate bubbles, so as to realize the cleaning of the liquid storage tank 11. In the open state, the drainage channel 21 can discharge the cleaned sewage. In this way, it is beneficial to improve the internal cleaning degree of the indoor air conditioner 100, and can realize automatic cleaning, and can solve the problem that the condensed water remaining on the water storage tank is easy to breed bacteria and then produce mildew and peculiar smell. In addition, during the cleaning process, there is no need to disassemble, which reduces the cleaning cost.
[0052] In some embodiments, please refer to Figures 1 to 5 , the switching valve 22 includes a driving member 221 and a switching member 222. The driving member 221 is used to drive the switching member 222 to move, so that the switching member 222 opens or closes the drainage channel 21 and / or the drainage hole 12.
[0053] The driving member 221 is a device capable of providing power and is used to drive the switching member 222 to move. The specific type of the driving member 221 is not limited herein. For example, it can be a motor, an electromagnetic device, etc.
[0054] In some embodiments, the driving member 221 is equipped with a controller, which can realize remote control or automatic control of the opening and closing of the switching valve 22. For example, the action of the switching valve 22 can be automatically controlled according to the liquid level height in the liquid storage tank 11.
[0055] The switching member 222 is a component that actually opens or closes the drainage channel 21 and / or the drainage hole 12 in the switching valve 22. The specific structure of the switching member 222 is not limited herein. For example, it can be a valve, a baffle, etc.
[0056] The switching member 222 can cooperate with the drainage channel 21, or with the drainage hole 12. Of course, it can also cooperate with the drainage channel 21 and the drainage hole 12 at the same time to prevent the discharge of condensed water. In addition, the switching member 222 can also be driven by the driving member 221 to switch between the states of cooperation and disengagement to correspondingly close and open the drainage channel 21 and / or the drainage hole 12.
[0057] The joint between the switching member 222 and the drainage channel 21 and / or the drainage hole 12 should have good sealing performance to prevent the leakage of condensed water. Exemplarily, the switching member 222 is made of rubber material. When the switching member 222 cooperates with the drainage channel 21 and / or the drainage hole 12, the rubber material deforms to achieve an interference fit with the drainage channel 21 and / or the drainage hole 12, thereby realizing the sealing at the joint.
[0058] The driving member 221 and the switching member 222 form a switching valve 22. The driving member 221 is responsible for providing power to drive the switching member 222 to move, and the opening or closing operation of the drainage channel 21 and / or the drainage hole 12 is realized through the movement of the switching member 222, thereby controlling the discharge of condensed water. The structure is simple, which is beneficial to improving the automation degree of the air conditioner indoor unit 100.
[0059] In some embodiments, referring to Figures 1 to 5 , a receiving cavity 13 is provided on the chassis 1. The drainage channel 21 communicates with the drainage hole 12 through the receiving cavity 13, and the switching valve 22 is disposed in the receiving cavity 13.
[0060] The receiving cavity 13 is a specifically provided space area on the chassis 1 of the air conditioner indoor unit 100 for receiving and installing the switching valve 22.
[0061] The specific structure of the receiving cavity 13 is not limited herein and is specifically determined according to the structure of the switching valve 22.
[0062] Both the drainage channel 21 and the drainage hole 12 communicate with the receiving cavity 13. Condensed water can flow to the receiving cavity 13 through the drainage hole 12 and then flow from the receiving cavity 13 to the drainage channel 21.
[0063] Exemplarily, the bottom of the liquid storage tank 11 has a certain thickness. The receiving cavity 13 is opened at the bottom of the liquid storage tank 11. The top of the receiving cavity 13 communicates with the drainage hole 12, and the bottom communicates with the drainage channel 21.
[0064] In some embodiments, a sensor is disposed in the receiving cavity 13 to detect parameters such as the flow rate and pressure of condensed water, so as to better control the action of the switching valve 22.
[0065] In some embodiments, the receiving cavity 13 can be partitioned to isolate the switching valve 22 from other components that may affect its normal operation, thereby improving the stability of the system.
[0066] In some embodiments, an anti-corrosion and anti-scaling coating is provided on the inner wall of the receiving cavity 13 to extend the service life of the receiving cavity 13 and ensure the smoothness of the drainage system at the same time.
[0067] By providing a receiving cavity 13 on the chassis 1, the receiving cavity 13 serves to connect the drainage channel 21 and the drainage hole 12, enabling the condensed water in the drainage channel 21 to flow through the receiving cavity 13 towards the drainage hole 12. Meanwhile, the switching valve 22 is disposed within this receiving cavity 13, facilitating a more compact and orderly structure for the entire drainage system.
[0068] In some embodiments, referring to Figures 1 to 5 , the driving member 221 includes an electromagnetic telescopic device 2211, and the electromagnetic telescopic device 2211 is used to drive the switching member 222 away from or towards the drainage hole 12, so that the switching member 222 opens or closes the drainage hole 12.
[0069] The electromagnetic telescopic device 2211 is a device that utilizes the electromagnetic principle to achieve telescopic motion. By energizing to generate a magnetic field, the internal components undergo telescopic changes, thereby driving the switching member 222 away from or towards the drainage hole 12.
[0070] Here, when the electromagnetic telescopic device 2211 drives the switching member 222 away from the drainage hole 12, that is, the switching member 222 is disengaged from the drainage hole 12, and the switching member 222 does not block the normal discharge of condensed water from the drainage hole 12. When the electromagnetic telescopic device 2211 drives the switching member 222 towards the drainage hole 12 until the switching member 222 is fully engaged with the drainage hole 12, the switching member 222 blocks the discharge of condensed water from the drainage hole 12.
[0071] Exemplarily, the switching member 222 is a rubber member corresponding to the drainage hole 12. When the liquid storage tank 11 does not need to be cleaned, the electromagnetic telescopic device 2211 drives the switching member 222 away from the drainage hole 12 for a long time, and the drainage hole 12 is opened. When the air conditioner indoor unit 100 is operating normally, the generated condensed water can be discharged normally through the drainage hole 12. When the liquid storage tank 11 needs to be cleaned, the electromagnetic telescopic device 2211 drives the switching member 222 towards the drainage hole 12, the switching member 222 deforms and is in interference fit with the drainage hole 12, the drainage hole 12 is closed, and the liquid storage tank 11 stores water for cleaning. After cleaning, the electromagnetic telescopic device 2211 drives the switching member 222 away from the drainage hole 12 for sewage drainage.
[0072] In some embodiments, the electromagnetic telescopic device 2211 is equipped with an intelligent control system to automatically adjust the degree and speed of telescoping according to different situations, so as to better control the switching member 222 and achieve control of the condensed water discharge speed.
[0073] In some embodiments, the electromagnetic telescopic device 2211 is subjected to a sealing treatment to prevent it from being damaged by condensed water or the external environment.
[0074] The driving member 221 of the air conditioner indoor unit 100 adopts an electro-magnetic telescopic device 2211, which can drive the switching member 222 away from or close to the drain hole 12. When the electro-magnetic telescopic device 2211 drives the switching member 222 close to the drain hole 12, the switching member 222 closes the drain hole 12 to prevent the condensed water from discharging; when driving the switching member 222 away from the drain hole 12, the switching member 222 opens the drain hole 12, so that the condensed water can be discharged. The electro-magnetic telescopic device 2211 has a fast response speed and can open or close the drain hole 12 in time according to needs, improving the working efficiency of the air conditioner indoor unit 100. The electro-magnetic telescopic device 2211 has high reliability and stability, can work stably for a long time, and reduces the maintenance cost of the equipment.
[0075] In some embodiments, please refer to Figures 1 to 5 , the chassis 1 is provided with an overflow hole 14, and the overflow hole 14 is higher than the drain hole 12; the drainage assembly 2 further includes an overflow channel 23, and the overflow channel 23 communicates with the liquid storage tank 11 through the overflow hole 14.
[0076] The overflow hole 14 is a hole provided on the chassis 1, and its position is higher than the drain hole 12. When the water level of the condensed water in the liquid storage tank 11 reaches a certain height, the excess water can flow out from the overflow hole 14.
[0077] The specific setting position of the overflow hole 14 is not limited here, and it is specifically determined according to the designed liquid storage capacity of the liquid storage tank 11. It can be understood that the larger the designed liquid storage capacity of the liquid storage tank 11, the higher the setting position of the overflow hole 14.
[0078] Here, the overflow hole 14 is higher than the drain hole 12, that is, when the water level line of the condensed water in the liquid storage tank 11 does not submerge the overflow hole 14, the overflow hole 14 can be normally discharged through the drain hole 12. Only when the condensed water generated by the air conditioner indoor unit 100 is too much and the drain hole 12 cannot discharge the condensed water in time, or when the drain hole 12 is in a closed state to store water, the water level line of the condensed water submerges the overflow hole 14, and the overflow hole 14 can discharge the condensed water exceeding the set capacity, preventing the condensed water in the liquid storage tank 11 from overflowing to other components of the air conditioner indoor unit 100 and causing damage.
[0079] The overflow channel 23 is a channel connected to the overflow hole 14 for guiding the condensed water flowing out from the overflow hole 14 to a specific position, preventing the condensed water from flowing to other components of the air conditioner indoor unit 100 and causing damage.
[0080] In some embodiments, a flow sensor is provided in the overflow channel 23 for detecting the occurrence of the overflow situation and sending out an alarm in time to remind the user to check and repair.
[0081] In some embodiments, when the overflow situation occurs, the drain hole 12 is opened to ensure that the condensed water can be smoothly discharged until there is no overflow.
[0082] The design of the flow holes and the overflow channel 23 can provide an additional drainage path in the event of a failure of the drainage hole 12 or an abnormal increase in condensate, preventing the water in the liquid storage tank 11 from overflowing and damaging other components of the air conditioner indoor unit 100, thereby improving the safety of the equipment.
[0083] In some embodiments, referring to Figures 1 to 5 , one end of the overflow channel 23 away from the overflow hole 14 communicates with the drainage channel 21.
[0084] One end of the overflow channel 23 of the air conditioner indoor unit 100 away from the overflow hole 14 communicates with the drainage channel 21. In this way, when the water level of the condensate in the liquid storage tank 11 rises to the height of the overflow hole 14, the condensate flowing out of the overflow hole 14 will enter the overflow channel 23, then flow into the drainage channel 21 through the connection with the drainage channel 21, and finally be discharged to a specific location.
[0085] In some embodiments, a one-way valve is provided at the connection between the overflow channel 23 and the drainage channel 21 to prevent the water in the drainage channel 21 from flowing back into the overflow channel 23.
[0086] Connecting the overflow channel 23 with the drainage channel 21 enables the condensate flowing out of the overflow hole 14 to directly enter the drainage channel 21 and be discharged, improving the drainage efficiency and avoiding damage caused by the accumulation of condensate inside the air conditioner indoor unit 100. There is no need to separately set up a complex drainage system for the overflow channel 23, and by utilizing the existing drainage channel 21, the structure of the entire air conditioner indoor unit 100 becomes more concise and compact.
[0087] In some embodiments, referring to Figures 1 to 5 , the drainage hole 12 is provided at the lowest point of the liquid storage tank 11.
[0088] The drainage hole 12 is provided at the lowest point of the liquid storage tank 11. This means that when there is condensate in the liquid storage tank 11, due to the action of gravity, the water will naturally flow to the lowest point, and thus can be discharged more smoothly through the drainage hole 12.
[0089] In some embodiments, a small water collection area is designed at the lowest point of the liquid storage tank 11, and the drainage hole 12 is provided within this water collection area to further improve the drainage efficiency. For example, a funnel structure is provided at the lowest point of the liquid storage tank 11, and the drainage hole 12 is opened at the bottom of the funnel structure.
[0090] Setting the drainage hole 12 at the lowest point of the liquid storage tank 11 can make full use of the gravity effect to quickly discharge the condensate, avoiding water accumulation in the liquid storage tank 11. It can minimize the residue of condensate in the liquid storage tank 11 and reduce the possibility of bacteria growth and odor generation.
[0091] In some embodiments, refer to Figures 1 to 5 , the bubble generating device 3 is disposed at the lowest position of the liquid storage tank 11.
[0092] The bubble generating device 3 is disposed at the lowest position of the liquid storage tank 11. This means that the bubble generating device 3 is at the position where condensed water in the liquid storage tank 11 is most likely to accumulate. When the bubble generating device 3 operates, it can directly generate bubbles in the condensed water at the bottom of the liquid storage tank 11, thereby more effectively cleaning the liquid storage tank 11.
[0093] In some embodiments, a flow guiding structure is disposed around the bubble generating device 3, so that the generated bubbles can be more evenly distributed in the liquid storage tank 11, improving the cleaning effect.
[0094] Disposing the bubble generating device 3 at the lowest position of the liquid storage tank 11 can directly clean the area where dirt and impurities are most likely to accumulate, improving the cleaning efficiency. At the same time, such a setting does not occupy too much space in the liquid storage tank 11, and can also make full use of the structural characteristics of the liquid storage tank 11, making the layout of the entire air conditioner indoor unit 100 more reasonable.
[0095] Next, the operation method of the air conditioner indoor unit 100 will be described.
[0096] In some embodiments, refer to Figures 1 to 5 , the air conditioner indoor unit 100 has a self-cleaning mode, and the operation method of the air conditioner indoor unit 100 is as follows:
[0097] Control the air conditioner indoor unit 100 to turn on the self-cleaning mode.
[0098] The self-cleaning mode is an operation mode of the air conditioner indoor unit 100. In this mode, the liquid storage tank 11 can be cleaned. In the self-cleaning mode, the evaporator 4 of the air conditioner indoor unit 100 generates condensed water, and the condensed water gathers and drips into the liquid storage tank 11.
[0099] Control the switch valve 22 to close the drainage channel 21 and / or the drainage hole 12.
[0100] A device capable of controlling the drainage channel 21 and / or the drainage hole 12 to open or close. Here, by controlling the switch valve 22 to close, thus, the liquid storage tank 11 can store the condensed water generated by the air conditioner indoor unit 100, preparing for the subsequent bubble generating device 3 to act on the condensed water to generate bubbles to clean the liquid storage tank 11.
[0101] Detect whether the air conditioner indoor unit 100 meets the cleaning conditions.
[0102] The cleaning conditions here refer to the storage amount of condensed water in the liquid storage tank 11, meeting the condition that the bubble generating device 3 can act on the condensed water to generate bubbles. The specific judgment basis is not limited herein.
[0103] If it is determined that the cleaning condition is met, the bubble generating device 3 is controlled to start to clean the liquid storage tank 11.
[0104] The bubble generating device 3 cleans the liquid storage tank 11 by generating bubbles. In some embodiments, the bubble generating device 3 uses a mechanical structure, such as a rotating component or a vibrating device, to make the condensed water generate turbulence, so as to mix air to form bubbles. In other embodiments, the bubble generating device 3 generates energy through an electrical device, such as an ultrasonic generator, etc., to cause physical changes in the condensed water, thereby generating bubbles.
[0105] During the process of the bubbles rising in the condensed water, they will drive the surrounding water flow to move, forming agitation of the water flow. This agitation can make the condensed water in the liquid storage tank 11 flow continuously, prevent impurities in the condensed water from precipitating at the bottom of the liquid storage tank 11, and thus keep the liquid storage tank 11 clean. At the same time, when the bubbles burst, they will release a certain amount of energy, and this energy can impact the inner wall of the liquid storage tank 11, which helps to remove dirt and bacteria attached to the inner wall of the liquid storage tank 11. In addition, in some embodiments, the air in the bubbles can chemically react with certain substances in the condensed water, such as oxidation, so as to decompose some organic pollutants and further improve the cleaning effect.
[0106] If it is determined that the cleaning is completed, the control switch valve 22 is controlled to open the drainage channel 21 and / or the drainage hole 12.
[0107] After the cleaning is completed, the dirty substances on the liquid storage tank 11 are mixed in the condensed water. The control switch valve 22 is controlled to open the drainage channel 21 and / or the drainage hole 12. The dirty substances are mixed in the condensed water and discharged with the condensed water, so as to realize the cleaning of the liquid storage tank 11.
[0108] The control method of the air conditioner indoor unit 100 provided by the embodiment of the present application realizes the orderly discharge of condensed water by arranging a liquid storage tank 11 on the chassis 1 to store the condensed water generated by the evaporator 4, and the drainage channel 21 is communicated with the liquid storage tank 11 through the drainage hole 12, reducing the damage of other components of the air conditioner indoor unit 100 caused by the contact of the condensed water with other components of the air conditioner indoor unit 100. By setting the switch valve 22 to control the opening and closing of the drainage channel 21 and / or the drainage hole 12, in the closed state, the water storage tank can store water. The bubble generating device 3 arranged in the liquid storage tank 11 acts on the stored condensed water to generate bubbles, realizing the cleaning of the liquid storage tank 11. In the open state, the drainage channel 21 can discharge the cleaned sewage. In this way, it is beneficial to improve the internal cleaning degree of the air conditioner indoor unit 100, can realize automatic cleaning, can solve the problem that the condensed water remaining on the water storage tank is easy to breed bacteria and then produce mildew and strange smells. In addition, no disassembly is required during the cleaning process, reducing the cleaning cost.
[0109] In some embodiments, please refer toFigures 1 to 5 The switching valve 22 includes an electrostrictive device 2211 and a switching member 222.
[0110] The electrostrictive device 2211 is a device that uses the electromagnetic principle to achieve telescopic motion. By applying an electric current to generate a magnetic field, the internal components undergo telescopic changes, thereby driving the switching member 222 away from or closer to the drain hole 12.
[0111] Controlling the switching valve 22 to close the drainage channel 21 and / or the drain hole 12 includes: controlling the electrostrictive device 2211 to drive the switching member 222 closer to the drain hole 12 so that the switching member 222 closes the drain hole 12.
[0112] The electrostrictive device 2211 drives the switching member 222 closer to the drain hole 12 until the switching member 222 is fully engaged with the drain hole 12, and the switching member 222 blocks the condensed water from being discharged from the drain hole 12.
[0113] Controlling the switching valve 22 to open the drainage channel 21 and / or the drain hole 12 includes: controlling the electrostrictive device 2211 to drive the switching member 222 away from the drain hole 12 so that the switching member 222 opens the drain hole 12.
[0114] The electrostrictive device 2211 drives the switching member 222 away from the drain hole 12, that is, the switching member 222 is disengaged from the drain hole 12, and the switching member 222 does not block the normal discharge of the condensed water from the drain hole 12.
[0115] The driving member 221 of the air conditioner indoor unit 100 adopts the electrostrictive device 2211, which can drive the switching member 222 away from or closer to the drain hole 12. When the electrostrictive device 2211 drives the switching member 222 closer to the drain hole 12, the switching member 222 closes the drain hole 12 to prevent the condensed water from being discharged; when the switching member 222 is driven away from the drain hole 12, the switching member 222 opens the drain hole 12 so that the condensed water can be discharged. The electrostrictive device 2211 has a fast response speed and can open or close the drain hole 12 in a timely manner according to needs, improving the working efficiency of the air conditioner indoor unit 100. The electrostrictive device 2211 has high reliability and stability, can work stably for a long time, and reduces the maintenance cost of the equipment.
[0116] In some embodiments, referring to Figures 1 to 5 , detecting whether the air conditioner indoor unit 100 meets the cleaning condition includes: determining whether the air conditioner indoor unit 100 meets the cleaning condition based on the water level of the condensed water in the liquid storage tank 11.
[0117] In some embodiments, a water level sensor is disposed within the liquid storage tank 11. After the water level reaches the set position, the sensor responds, indicating whether the air conditioner indoor unit 100 meets the cleaning condition. The specific setting position of the sensor is determined according to the actual situation, and the set position should meet the water level condition that the bubble generating device 3 can act with the condensed water to generate bubbles.
[0118] Based on the operating time of the air conditioner indoor unit 100, it is determined whether the air conditioner indoor unit 100 meets the cleaning condition.
[0119] In some embodiments, when it can be measured that the water level of the condensed water in the liquid storage tank 11 reaches the water level condition that the bubble generating device 3 can act with the condensed water to generate bubbles, the time length from the start of the self-cleaning mode to reaching the water level condition is measured. Through multiple experiments and taking the average value, the set time is obtained. Thus, when the set time is reached after the self-cleaning mode is started, it can be considered that the air conditioner indoor unit 100 meets the cleaning condition.
[0120] By measuring data in various ways to determine whether the air conditioner indoor unit 100 meets the cleaning condition, the judgment principle is simple, which is beneficial to the automatic control of the air conditioner indoor unit 100.
[0121] In some embodiments, please refer to Figures 1 to 5 , based on the operating time of the bubble generating device 3, it is determined whether the air conditioner indoor unit 100 is cleaned.
[0122] The time required for the bubble generating device 3 to clean the liquid storage tank 11 with different degrees of dirt can be measured. Through multiple experiments, a suitable time is selected as the completion time. When the operating time of the bubble generating device 3 reaches the completion time, it can be considered that the air conditioner indoor unit 100 is cleaned.
[0123] In some embodiments, the degree of dirt of the liquid storage tank 11 can be determined according to the time from the current self-cleaning mode to the start of the previous self-cleaning mode, and corresponding different completion times can be set according to the liquid storage tank 11 with different degrees of dirt.
[0124] In some embodiments, to improve the cleaning effect, under the condition of the liquid storage tank 11 with the same degree of dirt, the set completion time can be selected as the maximum completion time measured in the experiment. In some other embodiments, the set completion time can also be slightly greater than the measured maximum completion time.
[0125] By determining whether the air conditioner indoor unit 100 is cleaned based on the operating time of the bubble generating device 3, no personnel observation is required, the principle is simple, which is beneficial to automatic control and also beneficial to cost reduction.
