[0048] Embodiment 1

[0049] The air conditioner indoor unit of this embodiment includes a housing 10, a heat exchanger 12, a fan 13, a guide plate 20, a dehumidifying device, etc., as shown in Figures 1 to 7 shown.

[0050] The housing 10 has an air inlet and an air outlet 11, and a duct communicating the air inlet and the air outlet 11 is provided inside it. A heat exchanger 12 and a fan 13 are arranged in the duct.

[0051] The guide plate 20 is movably installed at the air outlet 11 to expose or block the air outlet 11. The guide plate 20 moves relative to the air outlet 11, thereby controlling the exposed or blocked area of the air outlet 11.

[0052] In some embodiments of the present application, a driving mechanism is provided inside the housing 10. The guide plate 20 is respectively rotatably connected to the left side plate and the right side plate of the housing 10, and the driving mechanism drives the guide plate 20 to rotate to expose or block the air outlet 11.

[0053] The dehumidifying device includes a containing box 30 and a water-absorbing component located inside the containing box 30. The containing box 30 is provided with a plurality of ventilation holes 32-2 to facilitate the water-absorbing component to absorb moisture; the containing box 30 is installed on the inner surface of the guide plate 20.

[0054] The water-absorbing component has strong water absorption, and the plurality of ventilation holes 32-2 on the containing box 30 facilitate the water-absorbing component to absorb moisture.

[0055] After the air conditioner enters the high-temperature self-cleaning mode, the guide plate 20 closes to block the air outlet 11, and the dehumidifying device is located inside the housing 10, as shown in Figure 1 shown. In the high-temperature self-cleaning mode, the moisture in the high-humidity steam generated in the high-temperature drying stage is absorbed by the water-absorbing component (such as high-absorbency resin) inside the containing box 30, reducing the humidity inside the housing 10. After exiting the high-temperature self-cleaning mode, the guide plate 20 opens to expose the air outlet 11. Since the high-humidity steam has been absorbed by the water-absorbing component, the indoor humidity will not be increased when the air conditioner blows air, avoiding affecting the user experience.

[0056] The indoor air conditioner of this embodiment installs a receiving box 30 on the inner surface of the guide plate 20. The receiving box 30 is provided with a water-absorbing component inside, and the receiving box 30 is provided with a plurality of ventilation holes 32-2 to facilitate the water-absorbing component to absorb moisture. The water-absorbing component has high water absorption and can efficiently and quickly absorb the moisture in the air duct, reducing the air humidity in the air duct. When the guide plate 20 is opened to expose the air outlet 11, the air blown out from the air outlet 11 will not affect the indoor humidity, solving the technical problem in the prior art that the air blown out from the air outlet after the self-cleaning mode ends affects the indoor humidity, and avoiding the self-cleaning mode from affecting the indoor humidity.

[0057] In some embodiments of the present application, the receiving box 30 is detachably installed on the inner surface of the guide plate 20, which is convenient for disassembly and assembly to facilitate the replacement of the internal water-absorbing component.

[0058] The receiving box 30 includes a box body 31 and a box cover 32 that are detachably connected together. The box cover 32 is detachably installed on the box body 31, and the box body 31 is detachably installed on the inner surface of the guide plate 20, which is convenient for disassembly and assembly. When it is necessary to replace the internal water-absorbing component, first detach the box body 31 and the box cover 32 as a whole from the inner surface of the guide plate 20, then detach the box cover 32 from the box body 31, and then replace the water-absorbing component.

[0059] The upper surface of the box cover 32 is provided with a plurality of strip-shaped arc grooves 32-1 arranged at intervals along the length direction of the box cover 32; the length direction of the strip-shaped arc grooves 32-1 is parallel to the width direction of the box cover 32, and the strip-shaped arc grooves 32-1 extend from one side of the box cover 32 to the other side of the box cover 32. The strip-shaped arc grooves 32-1 are provided with ventilation holes 32-2. Each strip-shaped arc groove 32-1 is provided with a plurality of ventilation holes 32-2.

[0060] The plurality of strip-shaped arc grooves 32-1 arranged at intervals form a wavy concave-convex structure on the surface of the box cover 32, increasing the surface area of the box cover 32, increasing the number of ventilation holes 32-2 arranged, and thus improving the water absorption speed of the water-absorbing component in the box body. Moreover, the strip-shaped arc grooves 32-1 also play a role in guiding air. The air flow flows along the strip-shaped arc grooves 32-1, prolonging the contact time with the surface of the box cover 32 and enhancing the water absorption effect of the water-absorbing component.

[0061] In some embodiments of the present application, the box body 31 is detachably clamped with the inner surface of the guide plate 20. The clamping of the box body 31 with the inner surface of the guide plate 20 is not only stable and reliable in connection, but also convenient for disassembly and assembly.

[0062] In some embodiments of the present application, the inner surface of the guide plate 20 is provided with an installation groove 24 and a clamping member 23. The box body 31 is located in the installation groove 24, and the clamping member 23 is close to the outer edge of the guide plate 20; the clamping member 23 is detachably clamped with the receiving box 30. The bottom of the box body 31 contacts the bottom of the installation groove 24, and the box body 31 is exposed from the installation groove 24.

[0063] Due to the clamping effect of the clamping member 23 and the blocking effect of the side wall of the installation groove 24, the accommodation box 30 is stably and reliably located in the installation groove 24, and there is no relative movement between the accommodation box 30 and the installation groove 24. When the guide plate 20 moves, the accommodation box 30 moves stably with the guide plate 20 and will not fall off.

[0064] By designing the above-mentioned clamping member 23 and installation groove 24, the stable and reliable connection between the accommodation box 30 and the guide plate 20 can be ensured, avoiding detachment, and the disassembly and assembly are convenient.

[0065] In some embodiments of the present application, each end of the guide plate 20 has a connecting rod, and the guide plate 20 is rotatably connected to the housing 10 through the two connecting rods. Specifically, one end of the guide plate 20 has a connecting rod 21, the other end of the guide plate 20 has a connecting rod 22, the connecting rod 21 is rotatably connected to the left side plate of the housing 10, and the connecting rod 22 is rotatably connected to the right side plate of the housing 10.

[0066] The clamping member 23 is located on one side of the box body 31, the two connecting rods are located on the other side of the box body 31, and the distance between the two connecting rods is less than the length of the box body 31. The two connecting rods not only play a role in rotatably connecting the guide plate 20 and the housing 10, but also can play a blocking role when the box body 31 slides out of the installation groove 24, avoiding the box body 31 from falling off the guide plate 20 and improving the safety of the box body 31.

[0067] In some embodiments of the present application, in order to facilitate timely reminding the user to replace the water absorption component, the air conditioner indoor unit further includes a weight detection device 40, a controller, an alarm device, etc.

[0068] The weight detection device 40 is located at the bottom of the box body 31 and is used to detect the weight of the dehumidification device 30 and send the detected weight signal to the controller.

[0069] The controller receives the weight signal sent by the weight detection device and generates an alarm signal according to the received weight signal. The controller controls the movement of the guide plate 20 and the operation of the entire air conditioner.

[0070] The alarm device alarms when receiving the alarm signal sent by the controller to remind the user to replace the water absorption component in time.

[0071] In some embodiments of the present application, the alarm device is an audible and visual alarm, including a buzzer and an alarm lamp, etc. When the audible and visual alarm receives the alarm signal, the buzzer sounds and the alarm lamp flashes.

[0072] The weight detection device 40 detects the weight of the dehumidification device and sends the detected weight signal to the controller. The controller controls the operation of the alarm device according to the received weight signal. When the received weight signal is greater than the preset threshold, the controller sends an alarm signal to the alarm device to control the alarm device to give an alarm, so as to remind the user that the water absorption component has absorbed enough water and needs to be replaced in time.

[0073] The controller can compare the received weight signal with the preset threshold through an internal comparator. According to the high and low levels output by the comparator, the size relationship between the weight signal and the preset threshold can be known. For example, when the comparator outputs a high level, it means that the weight signal is greater than the preset threshold, and the controller outputs an alarm signal to the alarm device to control the alarm device to give an alarm.

[0074] In some embodiments of the present application, the weight detection device 40 is a strain gauge pressure sensor. The strain gauge pressure sensor has stable performance and high sensitivity, and can accurately detect the weight of the dehumidification device.

[0075] In some embodiments of the present application, in order to further improve the detection accuracy of the strain gauge pressure sensor, the strain gauge pressure sensor is sheet-shaped, and its size is equal to the size of the bottom of the installation groove 24. It is installed at the bottom of the installation groove 24, see Figure 6 as shown.

[0076] First, install the strain gauge pressure sensor at the bottom of the installation groove 24, and then install the box body 31 in the installation groove 24. The bottom end surface of the strain gauge pressure sensor is in contact with the bottom of the installation groove 24, the top end surface of the strain gauge pressure sensor is in contact with the bottom end surface of the box body 31, and the bottom end surface of the box body 31 is entirely located on the strain gauge pressure sensor. The strain gauge pressure sensor can accurately detect the weight of the containing box and the water absorption component.

[0077] For example, the bottom of the installation groove 24 is rectangular, and the strain gauge pressure sensor is also rectangular. The length and width of the strain gauge pressure sensor are respectively equal to the length and width of the bottom of the installation groove 24.

[0078] In some embodiments of the present application, the clamping member 23 includes a side clamping portion 23-1 and a top clamping portion 23-2; one end of the side clamping portion 23-1 is connected to the inner surface of the guide plate 20, the other end of the side clamping portion 23-1 is connected to one end of the top clamping portion 23-2, the other end of the top clamping portion 23-2 is located above the box cover 32, and there is a gap between the other end of the top clamping portion 23-2 and the top surface of the box cover 32; the side clamping portion 23-1 abuts against the side surface of the box body 31. The clamping member 23 is integrally in an inverted L shape.

[0079] There is a gap between the other end of the top surface clamping part 23-2 and the top surface of the box cover 32, which avoids the top surface clamping part 23-2 pressing the box cover 32, and further avoids affecting the detection accuracy of the weight detection device 40.

[0080] By designing the clamping part 23 with the above structure, it is not only simple in structure, easy to implement, and low in cost, but also realizes the clamping with the accommodating box 30, ensuring that the accommodating box 30 is stably and reliably installed on the guide plate 20.

[0081] In some embodiments of the present application, the water-absorbing component is superabsorbent resin particles. The superabsorbent resin particles have super strong water absorption ability, good water absorption performance, and long service time.

[0082] In the air conditioner indoor unit of this embodiment, a detachable accommodating box 30 filled with superabsorbent resin particles is installed on the guide plate 20. A plurality of ventilation holes 32-2 are evenly formed on the surface of the accommodating box 30, which is convenient for the water-absorbing resin particles in the accommodating box 30 to absorb and release moisture. The accommodating box 30 is installed on the inner surface of the guide plate 20 through a clamping part 23 (such as a buckle), and there is a certain gap (space) between the accommodating box 30 and the top surface clamping part 23-2 of the clamping part 23 to prevent the top surface clamping part 23-2 from applying pressure to the accommodating box 30. A strain gauge pressure sensor is fixed at the bottom of the accommodating box 30 to sense the weight change caused by the absorption of moisture by the superabsorbent resin particles.

[0083] The air conditioner indoor unit of this embodiment relies on the super strong water absorption ability of the superabsorbent resin, which not only solves the problem of high-humidity air supply at the end of the current air conditioner self-cleaning mode, but also balances the indoor humidity to a certain extent.

[0084] In some embodiments of the present application, the controller controls the operation of the alarm device according to the comparison of the weights of the dehumidifying device before and after the high-temperature self-cleaning mode.

[0085] See Figure 8 , after the air conditioner enters the high-temperature self-cleaning mode, the guide plate 20 is closed. See Figure 1 As shown, the moisture in the high-humidity steam generated during the high-temperature drying stage is absorbed by the superabsorbent resin in the accommodating box 30; after exiting the high-temperature self-cleaning mode, the guide plate 20 returns to the fully open mode. See Figure 3As shown in the figure, at this time, the weight of the accommodation box 30 changes due to water absorption. The weight of the accommodation box 30 (including the weight of the internal superabsorbent resin particles) is collected by the strain gauge pressure sensor using the strain effect, and the weight value m3 is obtained. Compare m3 with the weight m2 (including the weight of the internal superabsorbent resin particles) of the accommodation box 30 before the high-temperature self-cleaning this time. If m3 > m2, it indicates that the superabsorbent resin in the accommodation box 30 still has water absorption capacity, and the guide plate will normally enter the closed state during the next high-temperature self-cleaning. If m3 ≤ m2, it indicates that the superabsorbent resin does not absorb water during this process, that is, the superabsorbent resin reaches the water absorption limit or is damaged. Since the superabsorbent resin is inexpensive and its water absorption volume can reach 100 - 1000 times its own volume, it will not reach the water absorption limit in the short term. Therefore, these two situations (reaching the water absorption limit or being damaged) are not distinguished. At this time, the air conditioner indoor unit reports a fault, and the alarm device gives an alarm, indicating that the superabsorbent resin needs to be replaced. Just remove the accommodation box 30 and replace the resin particles inside. Use the comparator in the controller to compare the magnitudes of m3 and m2.

[0086] See Figure 9 As shown in the figure, in the non-high-temperature self-cleaning mode, first set the number of times n the air conditioner is used. Each time the air conditioner is turned on and runs, the number of times n is incremented by 1; set the threshold N for the number of times the air conditioner is in the dehumidification mode and the weight M of the accommodation box containing the superabsorbent resin when it reaches the water absorption limit. Record the number of times N that the air conditioner enters the dehumidification mode every n0 times. W .

[0087] If N W ≤ N, it indicates that the room is at a low humidity level during this period. Then, when the dehumidification mode is running, the guide plate is in the fully open state to reduce the loss of moisture in the superabsorbent resin particles and the humidification effect on the indoor air; after the air conditioner runs in the cooling or heating mode and reaches the target temperature, the guide plate is placed in the semi-open state. See Figure 2 As shown in the figure, in order to utilize the high-temperature dry air supply during the air supply, especially during heating, to enhance the moisture loss of the superabsorbent resin particles and humidify the indoor air appropriately.

[0088] If N W > N, it indicates that the room is at a high humidity level during this period. Then, when the air conditioner runs in the cooling, dehumidification, and heating modes, the guide plate is in the fully open state. See Figure 3 As shown in the figure, to reduce the moisture loss of the superabsorbent resin and increase its absorption of moisture in the indoor air.

[0089] Through the above control, the superabsorbent resin particles play a role in balancing the indoor humidity to a certain extent. After each judgment, the number of times n of the air conditioner usage statistics is set to zero, and the next statistical cycle is entered.

[0090] In the air conditioner indoor unit of this embodiment, a detachable accommodation box 30 filled with superabsorbent resin particles is installed on the guide plate 20. The superabsorbent resin is used to absorb the moisture in the high-humidity air flow generated during the high-temperature self-cleaning process, effectively alleviating the discomfort caused to the human body during this process. At the same time, the superabsorbent resin absorbs and releases moisture indoors to achieve a certain degree of balance of indoor humidity, and a strain gauge pressure sensor is used to sense the change in the weight of the accommodation box caused by the superabsorbent resin absorbing moisture, so as to judge whether the superabsorbent resin has reached the water absorption limit or failed, so as to facilitate timely replacement of the superabsorbent resin particles in the accommodation box.

[0091] By counting the number of times N of the dehumidification mode in n0 air conditioner operation times W Compare with the preset dehumidification mode number threshold N to determine the humidity state of the room within a period of time, and then control the state of the guide plate 20 (an accommodation box 30 filled with superabsorbent resin particles is installed on the inner surface of the guide plate) in different operation modes to achieve humidification or dehumidification of the room by the superabsorbent resin, so as to balance the indoor humidity to a certain extent.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
