[0045] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, the preferred embodiments of the present invention are described in detail.

[0046] Reference Figures 1 to 3 As shown in the figure, an embodiment of the indoor air conditioner of the present invention is shown. The indoor air conditioner comprises a panel body 1 and a cleaning box 2, wherein the inner wall of the panel body 1 is provided with a mounting groove 11; the cleaning box 2 is detachably mounted in the mounting groove 11 and communicated with the air duct of the indoor air conditioner, and the cleaning box 2 is used to store a cleaning agent; wherein, when the self-cleaning mode is started, the air guide plate and the drain port of the indoor air conditioner are closed to seal the air duct, and the defrosting water dissolves the cleaning agent in the air duct and cleans the air duct under the action of the fan blades.

[0047] Specifically, the panel body 1 is provided with an air inlet and an air outlet, and an air duct is formed inside, so that the air flow enters the panel body 1 from the air inlet and flows along the air duct to the air outlet. A mounting groove 11 is also provided on the inner wall of the panel body 1, and the mounting groove 11 is used to install a cleaning box 2. The mounting groove 11 is formed by the inner wall of the panel body 1 being recessed inward; the indoor air conditioner also includes a cleaning box 2, and the cleaning box 2 is used to store cleaning agent. The cleaning box 2 is detachably installed in the mounting groove 11, that is, the cleaning box 2 can be removed at any time. The cleaning box 2 is connected to the air duct, so that the defrost water in the air duct can dissolve the cleaning agent in the cleaning box 2, and then under the action of the fan blades, the defrost water dissolved with the cleaning agent cleans the air duct and the fan blades.

[0048] When the self-cleaning mode is started, the detergent is poured into the cleaning box 2, and the cleaning box 2 is installed in the installation groove 11, and the controller controls the closing of the air guide plate and the drain port to form a closed space inside the panel body 1, that is, the air duct is closed at this time; therefore, when the evaporator undergoes the self-cleaning stage of frosting and defrosting, the defrosted water after defrosting gathers inside the air duct to avoid leakage of the defrost water, and the defrost water can be used to further clean the air duct and the fan blades; since the cleaning box 2 is connected to the air duct, the defrost water dissolves the detergent in the air duct, and then the fan blades are started to rotate, thereby driving the defrost water to flow, so that the defrost water dissolved with the detergent continuously flushes and cleans the air duct and the fan blades, thereby realizing self-cleaning of the air duct and the fan blades.

[0049] The present application is characterized in that the cleaning box 2 connected to the air duct is detachably connected to the panel body 1, and the cleaning agent is stored in the cleaning box 2, so that in the self-cleaning mode, the defrost water dissolves the cleaning agent and gathers in the air duct through the closed air duct, and under the action of the fan blades, the defrost water flushes the air duct and the fan blades to achieve self-cleaning of the air duct and the fan blades. The indoor air conditioner is used for further cleaning of the air conditioner after the defrost stage in the ordinary self-cleaning mode, and flushes some difficult-to-clean parts of the air duct and the fan blades, thereby improving the self-cleaning effect; and for air conditioners with a lot of dirt, a strong cleaning mode or a medium cleaning mode can be selected, while for air conditioners with less dirt, a normal cleaning mode can be directly selected, so that different cleaning measures can be taken for different degrees of dirt to achieve energy saving and accurate cleaning purposes, and the functionality is high; at the same time, by dissolving the cleaning agent, the self-cleaning effect of the air duct and the fan blades is further improved, and the cleaning intensity is high; further, the defrost water after defrosting is recycled to clean the air duct fan blades, saving energy and reducing costs.

[0050] In one embodiment, referring to Figure 1As shown, there are a plurality of mounting grooves 11, and the plurality of mounting grooves 11 are arranged at intervals along the length direction of the panel body 1 on one side of the air outlet of the panel body 1, and there are a plurality of cleaning boxes 2, and the plurality of cleaning boxes 2 are correspondingly detachably installed in the plurality of mounting grooves 11. Specifically, the panel body 1 is provided with a plurality of mounting grooves 11, and the plurality of mounting grooves 11 are arranged at intervals along the length direction of the panel body 1 on the panel body 1, and the mounting grooves 11 are located at the edge of the panel body 1 close to the air outlet, and the notches of the mounting grooves 11 face the position of the air outlet; at the same time, there are also a plurality of cleaning boxes 2, and the number of the cleaning boxes 2 corresponds to the number of the mounting grooves 11, one cleaning box 2 is correspondingly installed in one mounting groove 11, and the plurality of cleaning boxes 2 are correspondingly detachably installed in the plurality of mounting grooves 11, that is, the cleaning box 2 is located on the side of the panel body 1 close to the air outlet, so the cleaning box 2 The cleaning box 2 is in a lower position. After defrosting is completed, the defrost water gathers in the air duct. The cleaning box 2 is located at the bottom of the air duct, thereby improving the dissolution efficiency of the defrost water and the detergent and expanding the dissolution area, so that the defrost water and the detergent can be dissolved more fully, further improving the cleaning effect; at the same time, when the self-cleaning mode is started, the user can take out one or more of the cleaning boxes 2 from one or more of the installation slots 11 according to actual needs, and pour the detergent into the cleaning box 2, and finally reinstall the cleaning box 2 into the installation slot 11, thereby improving the applicability of the indoor air conditioner, meeting actual needs, and improving user experience.

[0051] In a specific embodiment, refer to Figures 2 to 3 As shown, the cleaning box 2 includes a box body 21 , and the box body 21 encloses a plurality of storage cavities 211 . The plurality of storage cavities 211 are adjacently arranged inside the box body 21 along the length direction of the box body 21 . Specifically, the cleaning box 2 includes a box body 21, and the box body 21 is used to store detergent. The box body 21 is enclosed to form a plurality of storage cavities 211, and the detergent is stored in the storage cavities 211. The plurality of storage cavities 211 are adjacently arranged inside the box body 21 along the length direction of the box body 21, and the plurality of storage cavities 211 have the same volume, that is, each of the storage cavities 211 can store a consistent amount of detergent. At the same time, when designing the volume size of the storage cavity 211, it is concluded through specific experimental results that the amount of detergent stored in one storage cavity 211 can correspond to the amount of mold cleaned, so that each of the storage cavities 211 can be regarded as a measurement unit, and the user can pour a certain amount of detergent into a specified number of the storage cavities 211 to better measure the amount of detergent, thereby adapting to cleaning under different degrees of dirtiness, improving user convenience, and reducing cleaning costs.

[0052] In one embodiment, referring to Figures 2 to 3 As shown, the top of the box body 21 is an inclined structure, and extends obliquely downward from the end of the box body 21 away from the air outlet toward the direction close to the air outlet. Specifically, the cleaning box 2 is installed on the side of the panel body 1 close to the air outlet. In order to fit the structure of the side of the panel body 1 close to the air outlet, in this embodiment, the top of the box body 21 is set as an inclined structure, and when the cleaning box 2 is installed in the installation groove 11, the side of the box body 21 away from the air outlet extends obliquely downward toward the direction close to the air outlet, so that when the cleaning box 2 is fully embedded in the installation groove 11, the top of the box body 21 can fit the structure of the side of the panel body 1 close to the air outlet, and the top of the cleaning box 2 is flush with the inner wall of the panel body 1, so as to improve the structural stability of the indoor air conditioner and prevent dust and other impurities from accumulating in the installation groove 11.

[0053] In a specific embodiment, refer to Figures 2 to 3 As shown, the cleaning box 2 further includes a box cover 22, the box cover 22 is rotatably connected to the box body 21, and the box cover 22 is located at the top of the box body 21. Specifically, the cleaning box 2 further includes a box cover 22, the box cover 22 is located at the top of the box body 21, and the box cover 22 is rotatably connected to the side of the box body 21 away from the air outlet, the box cover 22 is used to block impurities from falling into the storage cavity 211, thereby protecting the detergent from contamination and improving the structural stability of the cleaning box 2, and at the same time, the box cover 22 and the notch of the mounting groove 11 are mutually adapted, when the cleaning box 2 is installed in the mounting groove 11, the box cover 22 blocks the inside of the box body 21 and the mounting groove 11, so that the inner wall of the panel body 1 forms a complete structure, ensures that the airflow flows to the air outlet, and avoids the accumulation of impurities such as dust in the mounting groove 11, thereby improving the structural stability of the indoor air conditioner.

[0054] When entering the self-cleaning mode, the user can manually open the box cover 22, pour the detergent into the box body 21, and close the box cover 22. After the controller receives the detergent inversion, it closes the air guide plate and the drain port until the evaporator completes the frosting and defrosting stages. The defrost water collects in the air duct and dissolves the detergent. The fan blades are then controlled to rotate, and the fan blades generate centrifugal force. The fan blades will drive the defrost water dissolved with detergent to continuously flush and soak the air duct and fan blades, thereby achieving self-cleaning of the air duct and fan blades.

[0055] More specifically, the cleaning box 2 also includes a motor and a rotating shaft, wherein the rotating shaft connects the motor and the box cover 22, and the motor is fixed on the panel body 1 or the bottom shell, wherein the motor is started to drive the rotating shaft to rotate, thereby driving the box cover 22 to rotate, thereby realizing the operation of electrically opening or closing the box cover 22, saving manpower and making it more convenient for users.

[0056] In one embodiment, referring to Figure 3 As shown, the box cover 22 is provided with a plurality of through holes 221 penetrating the upper and lower ends thereof, and the plurality of through holes 221 are arranged at intervals along the length direction and the width direction of the box cover 22. Specifically, the box cover 22 is provided with a plurality of through holes 221, and the through holes 221 penetrate the upper surface and the lower surface of the box cover 22, thereby connecting the storage cavity 211 and the air duct, and the plurality of through holes 221 are arranged at intervals along the length direction and the width direction of the box cover 22, that is, the plurality of through holes 221 are in an array structure, thereby improving the dissolution rate of the defrosting water and the detergent, and improving the self-cleaning effect.

[0057] The embodiment of the present invention also provides a method for controlling an indoor air conditioner. Figures 8 to 10 is a schematic flow chart of the steps of the control method of the indoor air conditioner, Figure 4 is a flow chart of the control method of the indoor air conditioner, wherein the steps of the control method of the indoor air conditioner include S110-S140:

[0058] S110, receiving a power-on signal, obtaining a current mold coverage rate, and determining a difference between the current mold coverage rate and a preset mold coverage rate, wherein the preset mold coverage rate includes a first mold coverage rate, a second mold coverage rate, and a third mold coverage rate, and the first mold coverage rate is greater than the second mold coverage rate, and the second mold coverage rate is greater than the third mold coverage rate;

[0059] Specifically, the air conditioner includes a plurality of mold detection modules, which are respectively arranged at the parts that are easy to breed mold, such as the fan blades, evaporator, and air duct. The plurality of mold detection modules respectively detect the mold coverage rate of the fan blades, the evaporator, and the air duct, and send the mold coverage rate of the fan blades, the mold coverage rate of the evaporator, and the mold coverage rate of the air duct to the controller; the controller receives a power-on signal, and obtains a plurality of mold coverage rate data from the plurality of mold detection modules, calculates the total mold coverage rate of the three parts of the air duct, the fan blades, and the evaporator, so as to obtain the current mold coverage rate of the air conditioner, that is, the current mold coverage rate refers to the total mold coverage rate data on the fan blades, the air duct, and the evaporator; then the controller compares the current mold coverage rate with the preset mold coverage rate. The preset mold coverage rate refers to the empirical data obtained through multiple tests in advance, and the data is pre-stored on the controller, wherein the preset mold coverage rate includes a first mold coverage rate, a second mold coverage rate and a third mold coverage rate, and the first mold coverage rate is greater than the second mold coverage rate, and the second mold coverage rate is greater than the third mold coverage rate. By comparing the current mold coverage rate with the first mold coverage rate, the second mold coverage rate and the third mold coverage rate, the cleaning mode that the air conditioner needs to execute is determined, so that different cleaning measures should be taken for different degrees of dirt to achieve the purpose of energy saving and accurate cleaning and improve the cleaning effect.

[0060] S120, if the current mold coverage rate is greater than the first mold coverage rate, starting a strong cleaning mode;

[0061] Specifically, after comparing the current mold coverage rate with the preset mold coverage rate, when it is found that the current mold coverage rate is greater than the first mold coverage rate, it indicates that there is a lot of mold inside the air conditioner at this time, so the strong cleaning mode is started, and then the strong cleaning action is performed to improve the self-cleaning effect and ensure thorough cleaning.

[0062] In one embodiment, if Figure 5 As shown, step S120 also includes S121-S124.

[0063] S121, receiving strong cleaning mode instruction information, calculating the quantity information of the detergent according to the current mold coverage rate, and controlling the voice module to report the quantity information;

[0064] S122, receiving the addition completion information, controlling the air guide plate and the drain port to close, and turning on the cooling mode to frost;

[0065] S123, receiving frosting completion information, turning on the heating mode to defrost, and obtaining the water level of defrost water in real time;

[0066] S124, determining whether the water level is greater than a preset water level; if so, turning off the heating mode and turning on the fan blades for strong cleaning.

[0067] Specifically, when the current mold coverage rate is greater than the first mold coverage rate, it indicates that there are a lot of mold, impurities and other dirt on the air duct, fan blades and evaporator of the air conditioner. The voice module can be controlled to broadcast the judgment result and the recommended cleaning mode to the customer, or directly send the judgment result and the recommended cleaning mode information to the terminal. For example, the voice module can inform the user that "it is recommended to turn on the strong cleaning mode", and the terminal can display "it is recommended to turn on the strong cleaning mode"; after the user selects the strong cleaning mode according to the recommended cleaning mode, the controller receives the instruction information of the strong cleaning mode and calculates the required amount of detergent according to the current mold coverage rate.

[0068] More specifically, the calculation method of the grid amount of the cleaning agent is: the current mold coverage rate is S0, the preset mold coverage rate is S, the corresponding amount of cleaning agent to be injected is V, and V is the dosage of one grid; the mold coverage rate after cleaning once is S′; it is considered that the cleanliness of one grid dosage line is approximately (SS′); the actual required dosage V0=S0 / ((SS′)+V; rounding is used to compensate for errors and ensure the cleaning intensity.

[0069] After the controller calculates the required amount of detergent corresponding to the current mold coverage rate, it sends the amount information to the terminal or notifies the amount information through the voice module. For example, the voice module announces to the user "Add N grids of detergent in the cleaning box 2", and the N grids refer to the amount of detergent that needs to be filled.

[0070] After the user fills the cleaning box 2 with the required amount of detergent, the user closes the cleaning box 2 or puts the cleaning box 2 back into the installation slot 11; the controller receives the adding completion information, which means that the user has added the detergent, and the controller controls the air guide plate and the drain port to close so that the air duct forms an enclosed space, and turns on the refrigeration mode to perform the frosting stage on the evaporator.

[0071] When the controller receives the frosting completion information, it turns on the heating mode to execute the defrost stage. The defrost water after defrosting gathers in the air duct, and the water level of the defrost water is obtained in real time to monitor in real time whether the water level of the defrost water reaches the minimum standard, thereby ensuring the cleaning effect. At this time, the defrost water dissolves the detergent.

[0072] According to the water level, it is judged whether the water level is greater than the preset water level. The preset water level is a value preset in the controller. The preset water level should at least meet the height of the fan blades to ensure the cleaning effect of the fan blades. If the water level of the defrost water is greater than or equal to the preset water level, it proves that the water level of the defrost water is sufficient. At this time, the cleaning operation can be further performed. The controller can turn off the heating mode and start the fan blades to rotate and generate centrifugal force, thereby driving the defrost water dissolved with detergent to flush and soak the air duct and fan blades, so as to achieve a strong cleaning mode and improve the cleaning effect.

[0073] More specifically, if the water level of the defrost water is less than the preset water level, the control re-executes the frosting and defrosting steps until the water level of the defrost water is greater than the preset water level to ensure the cleaning effect; at the same time, if the heating defrost stage has not been completed and it is detected that the water level of the defrost water is greater than the preset water level, the heating defrost will continue to be completed until the defrost is completely completed and then the steps of turning off the heating mode and turning on the fan blades are executed.

[0074] S130: if the current mold coverage rate is less than the first mold coverage rate and greater than the second mold coverage rate, start a moderate cleaning mode;

[0075] Specifically, after comparing the current mold coverage rate with the preset mold coverage rate, it is found that the current mold coverage rate is less than the first mold coverage rate, and the current mold coverage rate is greater than the second mold coverage rate, that is, the current mold coverage rate is between the first mold coverage rate and the second mold coverage rate, indicating that there is more mold inside the air conditioner at this time, thereby starting the moderate cleaning mode and then performing the moderate cleaning action to improve the self-cleaning effect while reducing energy.

[0076] In one embodiment, if Figure 6 As shown, step S130 also includes S131-S133.

[0077] S131, receiving the instruction information of the medium cleaning mode, controlling the air guide plate and the drain port to close, and turning on the cooling mode to frost;

[0078] S132, receiving frosting completion information, turning on the heating mode to defrost, and obtaining the water level of defrost water in real time;

[0079] S133, determining whether the water level is greater than a preset water level, and if so, turning off the heating mode and turning on the fan blades for moderate cleaning;

[0080] Specifically, when the current mold coverage rate is greater than the second mold coverage rate and less than the first mold coverage rate, it indicates that there are more mold, impurities and other dirt on the air duct, fan blades and evaporator of the air conditioner. The voice module can be controlled to broadcast the judgment result and the recommended cleaning mode to the customer, or directly send the judgment result and the recommended cleaning mode information to the terminal. For example, the voice module can inform the user that "it is recommended to turn on the medium cleaning mode", and the terminal can display "it is recommended to turn on the medium cleaning mode"; after the user selects the medium cleaning mode according to the recommended cleaning mode, the controller receives the instruction information of the medium cleaning mode, thereby executing the action of the medium cleaning mode. First, the controller controls the air guide plate and the drain port to close so that the air duct forms a closed space, and turns on the cooling mode to perform the frosting stage on the evaporator.

[0081] When the controller receives the frosting completion information, it turns on the heating mode to execute the defrost stage. The defrost water after defrosting gathers in the air duct, and the water level of the defrost water is obtained in real time to monitor in real time whether the water level of the defrost water reaches the minimum standard, thereby ensuring the cleaning effect. At this time, the defrost water does not dissolve any detergent.

[0082] According to the water level, it is determined whether the water level is greater than a preset water level. The preset water level is a value preset in the controller. The preset water level should at least meet the height of the fan blades to ensure the cleaning effect of the fan blades. If the water level of the defrost water is greater than or equal to the preset water level, it proves that the defrost water has sufficient water. At this time, the cleaning operation can be further performed. The controller can turn off the heating mode and start the fan blades to rotate to generate centrifugal force, thereby driving the defrost water to flush and soak the air duct and the fan blades to achieve a moderate cleaning mode, thereby improving the cleaning effect while ensuring energy saving.

[0083] More specifically, if the water level of the defrost water is less than the preset water level, the control re-executes the frosting and defrosting steps until the water level of the defrost water is greater than the preset water level to ensure the cleaning effect; at the same time, if the heating defrost stage has not been completed and it is detected that the water level of the defrost water is greater than the preset water level, the heating defrost will continue to be completed until the defrost is completely completed and then the steps of turning off the heating mode and turning on the fan blades are executed.

[0084] S140, if the current mold coverage rate is less than the second mold coverage rate and greater than the third mold coverage rate, start the normal cleaning mode;

[0085] Specifically, after comparing the current mold coverage rate with the preset mold coverage rate, it is found that the current mold coverage rate is less than the second mold coverage rate, and the current mold coverage rate is greater than the third mold coverage rate, that is, the current mold coverage rate is between the second mold coverage rate and the third mold coverage rate, indicating that there is not much mold inside the air conditioner at this time, thereby starting the normal cleaning mode and then performing normal cleaning actions to improve the self-cleaning effect and save energy, and shorten the cleaning cycle.

[0086] In one embodiment, if Figure 7 As shown, step S140 also includes S141-S142.

[0087] S141, receiving the normal cleaning mode instruction information, turning on the cooling mode to frost;

[0088] S142, receiving frosting completion information, turning on the heating mode to defrost;

[0089] Specifically, when the current mold coverage rate is greater than the third mold coverage rate and less than the second mold coverage rate, it indicates that there is not much mold, impurities and other dirt on the air duct, fan blades and evaporator of the air conditioner. The voice module can be controlled to broadcast the judgment result and the recommended cleaning mode to the customer, or directly send the judgment result and the recommended cleaning mode information to the terminal. For example, the voice module can inform the user that "it is recommended to turn on the normal cleaning mode", and the terminal can display "it is recommended to turn on the normal cleaning mode"; after the user selects the normal cleaning mode according to the recommended cleaning mode, the controller receives the instruction information of the normal cleaning mode, thereby executing the action of the normal cleaning mode. First, the controller controls the opening of the cooling mode to perform the frosting action on the evaporator. When the controller receives the frosting completion information, it turns on the heating mode to execute the defrosting stage, and then washes away the mold and other impurities through the two stages of frosting and defrosting.

[0090] In another embodiment, if the current mold coverage rate is less than the third mold coverage rate, the normal operation mode is turned on; that is, when the current mold coverage rate is less than the third mold coverage rate, it indicates that there is less mold on the components in the air conditioner, and there is no need to perform the cleaning mode, and the demand mode selected by the user can be directly operated.

[0091] In another embodiment, the fan blades rotate according to a preset time to use defrost water to clean the air duct and the fan blades. After the cleaning is completed, the controller needs to turn on the heating mode to dry the air duct, fan blade evaporator. After the drying is completed, the current mold coverage rate of the air duct, fan blades, and evaporator is tested again. If the current mold coverage rate is greater than the preset mold coverage rate, continue to execute the above steps.

[0092] The control method of the indoor air conditioner of the present application can execute different cleaning modes according to different degrees of dirtiness. When the degree of dirtiness is severe, the strong cleaning mode is executed, that is, under the basic cleaning of frosting and defrosting, detergent and defrosting water are added to further clean the air duct and the air blades under the centrifugal action of the fan blades; when the degree of dirtiness is moderate, the moderate cleaning mode is executed, that is, under the basic cleaning of frosting and defrosting, defrosting water is further used to clean the air duct and the fan blades under the centrifugal action of the fan blades; when the degree of dirtiness is mild, the ordinary cleaning mode is executed, that is, the basic cleaning steps of frosting and defrosting are executed. By taking different cleaning measures according to different degrees of dirtiness, the purpose of energy saving and accurate cleaning can be achieved, thereby improving the cleaning effect.

[0093] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
