[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0038] The present application embodiment provides a dustproof mechanism for an air conditioner indoor unit. For example, please refer to Figure 1-Figure 2 , Figure 1 This is a first state diagram of the air conditioner indoor unit provided in an embodiment of the present application. Figure 2 This is a second state diagram of the air conditioner indoor unit provided in an embodiment of the present application. The air conditioner indoor unit 10 includes a main body 100 and a dustproof mechanism 200. The main body 100 is provided with an air inlet 110. The dustproof mechanism 200 includes a dustproof cover 210 and a drive device 220.

[0039] The dust cover 210 is used to be installed at the air inlet 110. The dust cover 210 includes a cover body 211 and a rotating shaft 212 that are connected to each other. The rotating shaft 212 is suitable for rotating with the main body 100; the driving device 220 is connected to the rotating shaft 212, and is used to drive the rotating shaft 212 to rotate so that the cover body 211 opens or covers the air inlet 110.

[0040] Illustratively, a rotation shaft groove is provided on the main body 100 , and the rotation shaft 212 cooperates with the rotation shaft groove so that the dust cover 210 is rotatably connected to the main body 100 .

[0041] The dust cover 210 may be made of plastic or a lightweight metal alloy. Preferably, the edges and corners of the dust cover 210 are rounded to improve aesthetics and safety.

[0042] The dustproof mechanism 200 of the air-conditioning indoor unit provided in the embodiment of the present application can effectively prevent dust from accumulating at the air inlet by adding a dustproof cover 210 at the air inlet of the air-conditioning indoor unit, and the driving device 220 directly drives the rotating shaft 212 to make the cover body 211 open or cover the air inlet. The overall structure is simple and aesthetically pleasing.

[0043] For further information, see Figure 3-Figure 4 , Figure 3 A schematic diagram of the structure of the dustproof mechanism provided in an embodiment of the present application is shown. Figure 4 for Figure 3 The driving device 220 includes a driving unit 221 and a transmission assembly 222 .

[0044] The driving unit 221 includes an output shaft 2211; the transmission assembly 222 includes an input end and an output end of the transmission connection, the input end of the transmission assembly 222 is connected to the output shaft 2211, and the output end of the transmission assembly 222 is connected to the rotating shaft 212. The driving unit 221 drives the rotating shaft 212 to rotate through the transmission assembly 222.

[0045] It should be noted that the drive unit 221 includes a stator part and a rotor part. The stator part is used to be fixedly installed on the main body 100, and the rotor part includes an output shaft 2211. The output shaft 2211 rotates relative to the stator part to make the rotating shaft 212 rotate relative to the main body 100; illustratively, the stator part is fixedly installed on the shell of the main body 100.

[0046] In some embodiments, a gear portion (not shown) is provided on the rotating shaft 212. The input end of the rotating shaft 212 includes an input gear 2221, and the output end of the rotating shaft 212 includes an output gear 2222. The input gear 2221 meshes with the output gear 2222. The input gear 2221 is fixedly mounted on the output shaft 2211, and the output gear 2222 meshes with the gear portion on the rotating shaft 212. The driving unit 221 is a rotary motor. It is understood that the driving unit 221 drives the output gear 2222 to rotate via the input gear 2221, and the output gear 2222 then drives the rotating shaft 212 to rotate relative to the main body 100.

[0047] In some embodiments, the user can choose to open and close the dust cover 210 electrically or manually. Exemplarily, the drive device 220 further includes a clutch assembly, the input end of which is in transmission connection with the drive unit 221. When the clutch assembly is in a first state, the output end of the clutch assembly is in transmission connection with the transmission assembly, i.e., the drive unit 221 is in transmission connection with the transmission assembly via the clutch assembly. When the clutch assembly is in a second state, the output end of the clutch assembly is disconnected from the transmission assembly, i.e., the drive unit 221 is disconnected from the transmission assembly via the clutch assembly. In actual application, the user switches the dust cover 210 between the electrically opened and closed function and the manually opened and closed function by controlling the clutch assembly to switch between the first state and the second state.

[0048] In some embodiments, as Figure 1-Figure 2 As shown, the cover body 211 includes a cover plate 2111 and a circumferential side plate 2112 connected to the edge of the cover plate 2111. When the cover body 211 covers the air inlet 110, the cover plate 2111 covers the top wall of the main body 100 where the air inlet 110 is opened, and the circumferential side plate 2112 is arranged around the side wall of the main body 100. In this way, the dust cover has a better dustproof effect.

[0049] To prevent the dust cover 210 from colliding with the main body and generating loud noise when closing the air inlet 110, a buffer member 2113 can be provided on the surface of the cover plate 2111 that faces the top wall of the main body 100 where the air inlet 110 is located. It should be noted that the buffer member 2113 is made of an elastic material, such as silicone, rubber, or sponge. Thus, when the dust cover 210 closes the air inlet 110, the buffer member 2113 comes into contact with the main body 100, and the buffering effect of the buffer member 2113 prevents loud noise from being generated. Preferably, when the dust cover 210 closes the air inlet 110, the buffer member 2113 is sandwiched between the cover plate 2111 and the top wall of the main body 100 and surrounds the air inlet 110. This not only provides a buffering effect but also prevents mosquitoes from crawling into the air inlet 110 through the gap between the cover plate 2111 and the main body 100, thereby affecting the cleanliness of the indoor unit 10.

[0050] In some embodiments, when the main body 100 is turned on, the driving device 220 drives the cover body 211 to open the air inlet 110 ; when the main body 100 is turned off, the driving device 220 drives the cover body 211 to cover the air inlet 110 .

[0051] It should be noted that the air conditioner indoor unit 10 has a controller, which controls the driving device 220 to operate in response to the user's power on and power off instructions for the indoor unit 10 , thereby controlling the cover body 211 to open or close the air inlet 110 .

[0052] In some embodiments, see Figure 5 , Figure 5 A structural diagram of a dustproof mechanism provided in an embodiment of the present application. The dustproof mechanism 200 further includes a sensor device 230, which is mounted on the main body 100 and configured to detect the temperature and humidity within the main body 100. After the main body 100 is powered off, when the temperature and humidity within the main body 100 reach a predetermined condition, the sensor device 230 generates a first feedback signal, and the drive device 220 drives the cover body 211 to cover the air inlet 110 in response to the first feedback signal.

[0053] The sensing device 230 may include a humidity sensor and a temperature sensor. The specific types of the humidity sensor and the temperature sensor can be selected according to actual needs and are not specifically limited here.

[0054] It should be noted that during operation of the air conditioner indoor unit 10, the indoor heat exchanger generates condensation, significantly increasing the internal humidity of the indoor unit 10, or the indoor heat exchanger generates heat, causing the internal temperature of the indoor unit 10 to become excessively high. However, the cover body 211 covering the air inlet 110 causes the interior of the indoor unit 10 to be relatively closed, making air exchange with the outside world difficult. If the cover body 211 covers the air inlet when the humidity or temperature inside the indoor unit 10 is excessively high, the interior of the air conditioner indoor unit 10 will be exposed to high humidity or high temperature for a long period of time. Exposed to such conditions for a long time, the internal components of the indoor unit 10 may suffer a shortened service life. It is understood that when the temperature and humidity inside the main body 100 reach the preset conditions, this should be after the main body 100 has been shut down and a period of time has passed, during which the temperature inside the main body 100 has gradually changed to a suitable temperature and humidity.

[0055] For example, the sensor device 230 is connected to the controller of the air conditioner indoor unit 10. When the sensor device 230 detects that the temperature and humidity inside the main body 100 have reached a preset temperature and a preset humidity, it sends a first feedback signal to the controller of the air conditioner indoor unit 10. After receiving the first feedback signal, the controller of the air conditioner indoor unit 10 controls the driving device 220 to operate, thereby controlling the cover body 211 to cover the air inlet 110. The preset humidity and preset temperature can be pre-set by the designer according to actual needs, or determined by the processor of the air conditioner indoor unit 10 based on the ambient temperature.

[0056] Preferably, the main body 100 includes a heat exchange cavity suitable for installing a heat exchanger, and the sensing device 230 is disposed in the heat exchange cavity of the main body 100 .

[0057] In a parallel embodiment, see Figure 6 , Figure 6 Another structural diagram of the dustproof mechanism provided in an embodiment of the present application. The dustproof mechanism includes a timing device 240 for timing. When the main body 100 is turned off, the timing device 240 begins timing and issues a second feedback signal when the timing reaches a preset duration. The driving device 220 is configured to drive the cover body 211 to cover the air inlet 110 in response to the second feedback signal.

[0058] It should be noted that when the timer reaches the preset time, the temperature inside the main body 100 should have gradually changed and reached an appropriate temperature, and the humidity inside the main body 100 should have gradually changed and reached an appropriate humidity. The preset time can be pre-set by the designer according to actual needs.

[0059] The dustproof mechanism 200 of the air-conditioning indoor unit provided in the embodiment of the present application can effectively prevent dust from accumulating at the air inlet by adding a dustproof cover 210 at the air inlet of the air-conditioning indoor unit. In addition, the driving device 220 directly drives the rotating shaft 212 to make the cover body 211 open or cover the air inlet 110. The overall structure is simple and aesthetically pleasing.

[0060] The embodiment of the present application further provides an air conditioner, the air conditioner comprising Figure 1-Figure 2 The air conditioner indoor unit 10 shown includes a main body 100 and a dustproof mechanism 200 in any of the above embodiments. It is understood that the air conditioner also includes at least an outdoor unit and a refrigerant pipe connected between the indoor unit and the outdoor unit.

[0061] Based on the air conditioner indoor unit 10, the present application provides a control method for the indoor unit 10. The main body 100 also includes a fan and a compressor. The control method includes:

[0062] In response to the power-on command, the control driving device 220 drives the cover body 211 to open the air inlet 110;

[0063] Control the start-up of fans and compressors;

[0064] In response to a shutdown instruction, controlling the compressor to stop;

[0065] Detecting whether the temperature and humidity inside the main body 100 meet the preset conditions;

[0066] If the temperature and humidity inside the main body 100 reach the preset conditions, the fan is controlled to shut down;

[0067] The control driving device 220 drives the cover body 211 to cover the air inlet 110 .

[0068] It can be understood that the indoor unit 10 of the present application needs to open the air inlet before turning on the fan, and close the air inlet after the fan is turned off, to ensure that the air inlet is in an open state during the operation of the fan, so that the indoor unit 10 can discharge air smoothly; in addition, when the indoor unit is turned off, the fan is delayed to shut down, which can accelerate the air convection between the inside of the main body 100 and the outside world, so that the temperature and humidity inside the main body 100 can reach the preset conditions as soon as possible.

[0069] In some embodiments, after controlling the driving device 220 to drive the cover body 211 to open the air inlet 110 in response to a power-on command, the control method further includes adjusting the opening and closing degree of the cover body 211 according to the temperature and humidity inside the main body 100. In this way, by adjusting the opening and closing degree of the cover body 211, the airflow distribution of the air inlet 110 can be adjusted, thereby improving the performance of the indoor unit 10 while ensuring the dust-proof function.

[0070] In some embodiments, the indoor unit 10 further includes a wireless communication module such as a WIFI module, a Bluetooth module or other wireless communication module, which is used to communicate wirelessly with the user's mobile terminal so that the user can remotely control the air conditioner through the mobile terminal.

[0071] The air conditioner provided in the embodiment of the present application can effectively prevent dust from accumulating at the air inlet by adding a dustproof mechanism 200 at the air inlet 110 of the indoor unit 10. When the indoor unit 10 is turned off, the dustproof cover 210 covers the air inlet 110, and the dustproof mechanism 200 directly drives the rotating shaft 212 to make the cover body 211 open or cover the air inlet 110. The overall structure is simple and aesthetically pleasing.

[0072] The above is a detailed introduction to the dust-proof mechanism of the air-conditioning indoor unit and the air-conditioning provided in the embodiments of the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for technical personnel in this field, based on the ideas of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
