[0037] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0038] The present invention provides an air conditioner indoor unit 10, Figure 1 1 is a schematic structural diagram of an air-conditioning indoor unit 10 according to an embodiment of the present invention, and is a schematic cross-sectional view of an air-conditioning indoor unit 10 according to an embodiment of the present invention.

[0039] Reference Figure 1 and Figure 2 The air conditioner indoor unit 10 may generally include a casing 110 and an air guide plate 120. An air outlet 111 is disposed at the bottom front side of the casing 110. The air guide plate 120 is rotatably connected to the air outlet 111 for controlling the opening and closing of the air outlet 111.

[0040] The air conditioner indoor unit 10 of this embodiment may further include a guide plate 130 and an atomizing air supply assembly 140, wherein the guide plate 130 is arranged below the casing 110, and a water storage chamber 131 is formed inside the guide plate 130, and the water storage chamber 131 can be used to store water for humidification. The guide plate 130 has a water adding hole 132 and an atomizing outlet hole connected to the water storage chamber 131, the water adding hole 132 can be arranged on the top of the guide plate 130, and the atomizing outlet hole can be arranged on the front side of the guide plate 130, and the atomizing air supply assembly 140 can be arranged in the water storage chamber 131, which is mainly used to atomize the humidification water and blow it out from the mist outlet hole 133, so as to adjust the indoor humidity.

[0041] In this embodiment, the front and rear dimensions of the air outlet 111 are larger than the front and rear dimensions of the air guide plate 120. The air guide plate 120 can be set in the front area of ​​the air outlet 111, and the guide plate 130 can be set below the rear area of ​​the air outlet 111 to cooperate with the air guide plate 120 to supply air and achieve a better air supply effect.

[0042] This embodiment eliminates the water tank in the conventional air conditioner indoor unit 10, and uses the guide plate 130 as an atomizing humidification structure, forms a water storage chamber 131 therein, and provides a water filling hole 132 connected to the water storage chamber 131. When the humidification water in the water storage chamber 131 is insufficient, the user can directly add water to the water storage chamber 131 through the water filling hole 132. Compared with the existing air conditioner indoor unit 10 with humidification function, it reduces the complexity of water filling and improves the convenience of water filling. Moreover, during the water filling process, the atomizing air supply component 140 can still work normally, which also improves the user experience.

[0043] The two ends of the casing 110 respectively have a first connecting arm 150 and a second connecting arm 160 extending downward, the lower ends of the first connecting arm 150 and the second connecting arm 160 are bent toward each other, and the guide plate 130 is connected between the lower ends of the first connecting arm 150 and the second connecting arm 160, so that it is horizontally suspended below the casing 110.

[0044] However, in actual applications, since the air-conditioning indoor unit 10 is installed at a higher position, the user needs to stand on a chair when replenishing humidification water into the water storage chamber 131 through the water filling hole 132, which may easily cause the humidification water to spill due to shaking, and there is also a risk of falling from the chair.

[0045] Figure 3 FIG. 1 is a schematic diagram of the connection structure of the guide plate 130 and the first connecting arm 150 and the second connecting arm 160 according to an embodiment of the present invention. Figure 3In order to solve the above problems, in this embodiment, the first end of the guide plate 130 is hinged to the first connecting arm 150, and a locking device 180 is provided between the second end of the guide plate 130 and the second connecting arm 160. The locking device 180 is configured to controllably lock and unlock the relative position between the second end of the guide plate 130 and the second connecting arm 160. During the water replenishment process, the lock on the second end of the guide plate 130 can be released, and then the guide plate 130 can be rotated downward around its first end as a whole, so that the water filling hole 132 on the guide plate 130 is in a lower position. The user can directly add humidification water to the water storage chamber 131 without standing at a high place, which greatly reduces the difficulty of water replenishment and further improves the safety and convenience of water replenishment operation.

[0046] A rotating shaft 171 and a shaft sleeve 172 may be connected between the first end of the guide plate 130 and the first connecting arm 150 , respectively. The rotating shaft 171 is inserted into the shaft sleeve 172 , so that the guide plate 130 can swing relative to the first connecting arm 150 after the locking device 180 is unlocked.

[0047] In this embodiment, the first connecting arm 150 can be located at the right end of the housing 110, and the second connecting arm 160 can be located at the left end of the housing 110. The right end of the guide plate 130 can be used as its first end, and the left end can be used as its second end. Two fixing plates 173 can be provided at the lower end of the first connecting arm 150. The two fixing plates 173 are arranged front and back and extend toward the guide plate 130. A rotating shaft 171 as mentioned above is fixed to the inner side of each fixing plate 173. Two rotating sleeves can be provided. Two shaft sleeves 172 are arranged front and back and extend between the two fixing plates 173. The two rotating shafts 171 are respectively inserted into the two shaft sleeves 172. In this way, the guide plate 130 and the first connecting arm 150 can be stably hinged.

[0048] The locking device 180 may include an electromagnetic buckle 181 and an electromagnetic slot 182, which are respectively disposed at the second end of the guide plate 130 and the second connecting arm 160. The electromagnetic buckle 181 and the electromagnetic buckle 182 can be locked and unlocked by turning on and off the power, and the operation is relatively simple and convenient.

[0049] In this embodiment, two electromagnetic clips 181 and two electromagnetic slots 182 are respectively provided, wherein the two electromagnetic clips are arranged front and back at the lower end of the second connecting arm 160 and extend toward the second end of the guide plate 130, and the two electromagnetic slots 182 are arranged front and back at the top of the second end of the guide plate 130. The shape of the electromagnetic slots 182 is adapted to the shape of the electromagnetic clips 181, and the two electromagnetic clips 181 are respectively adsorbed in the two electromagnetic slots 182, so that the second end of the guide plate 130 is firmly connected to the second connecting arm 160.

[0050] The housing 110 may be provided with a retractable device 190 at one end adjacent to the second connecting arm 160. Figure 4 1 is a schematic structural diagram of an air conditioner indoor unit 10 according to an embodiment of the present invention, in which the second connecting arm 160 is hidden and the retractable device 190 is exposed. Figure 4 The retracting device 190 can be configured to release or retract the second end of the drainage plate 130 in a controlled manner after the locking device 180 is unlocked, so that when water replenishment is needed, the second end of the drainage plate 130 is released, so that the drainage plate 130 rotates downward under its own gravity, so as to lower the height of the water filling hole 132, which is convenient for users to replenish water. After the water replenishment is completed, the second end of the drainage plate 130 is retracted and pulled to restore the drainage plate 130 to the initial straight state, so that the electromagnetic buckle 181 is adsorbed in the electromagnetic card slot 182, thereby fixing the second end of the drainage plate 130.

[0051] In this embodiment, the retractable device 190 may include a motor 191, a rope drum 192 and a cord 193, wherein the motor 191 is fixed to the inside of the housing 110, the rope drum 192 is fixedly connected to the output shaft of the motor 191, and the cord 193 is wound around the rope drum 192, and one end of the cord 193 is fixedly connected to the second end of the drain plate 130. Retracting the cord 193 by the motor 191 can replace the user pulling the drain plate 130 to rotate smoothly, simplifying the user operation and making the water replenishment operation more automated. In addition, in the case where the electromagnetic buckle 181 and the electromagnetic card slot 182 are unlocked due to an accidental power outage, the drain plate 130 can still remain in a straight state due to the pulling action of the cord 193, and will not rotate, which is safer.

[0052] In an optional embodiment of the present invention, a plurality of mist outlet holes 133 may be provided, and the plurality of mist outlet holes 133 are arranged at intervals on the front side of the guide plate 130 along the length direction of the guide plate 130. In addition, an atomizing air supply assembly 140 may be provided at a position corresponding to each mist outlet hole 133 in the water storage chamber 131. By controlling the atomizing air supply assemblies 140 to work simultaneously, the mist can be blown out from the guide plate 130 in a relatively dispersed manner, thereby achieving rapid and uniform humidification of the indoor environment, and improving the humidification speed and humidification effect.

[0053] Taking into account the case where multiple mist outlet holes 133 are set, in the process of rotating the second end of the guide plate 130 downward to replenish water, as the humidification water is filled, the humidification water in the water storage chamber 131 continues to increase, which will cause the humidification water to first flow out from the mist outlet hole 133 adjacent to the second end of the guide plate 130, resulting in a waste of humidification water.

[0054] Figure 5 is a schematic structural diagram of a guide plate 130 according to an embodiment of the present invention, Figure 6 is along Figure 5A schematic cross-sectional view taken along the cutting line AA in FIG. Figure 7 is along Figure 5 A schematic cross-sectional view taken along the cutting line BB in FIG.

[0055] Reference Figures 5 to 7 To solve the above problem, in this embodiment, a partition plate 134 is provided in the water storage chamber 131, and the partition plate 134 divides the interior of the water storage chamber 131 into a first chamber 131a and a second chamber 131b, and the first chamber 131a is located at the front side of the second chamber 131b, and the first end of the partition plate 134 has a water outlet 135 connecting the first chamber 131a and the second chamber 131b, the water adding hole 132 can be set at the top of the second chamber 131b, and the mist outlet hole 133 can be set at the front side of the first chamber 131a.

[0056] In this way, during the water replenishment process, the humidification water replenished through the water filling hole 132 will be temporarily stored in the second chamber 131b. After the second end of the guide plate 130 is lifted back to its original position, the humidification water can gradually flow from the second chamber 131b to the first chamber 131a through the water outlet 135, effectively avoiding the problem of humidification water flowing out of the mist outlet 133 during the water replenishment process, which is conducive to the smooth progress of the water replenishment operation.

[0057] Preferably, the distance between the water adding hole 132 and the second end of the guide plate 130 is not less than 1 / 2 of the length of the guide plate 130, for example 1 / 2, 3 / 4, 4 / 5, etc., and can be specifically set according to the characteristics of the guide plate 130 to ensure that the humidification water does not overflow from the water adding hole 132 during the water adding process, and after the guide plate 130 is lifted to a horizontal state, the position height of the humidification water in the first chamber 131a does not exceed the mist outlet hole 133.

[0058] When replenishing water into the second chamber 131b, the water level of the humidification water can be controlled near the water filling port, so that after the guide plate 130 is lifted to a flat state, more humidification water can enter the first chamber 131a for atomization, and the mist outlet 133 should be arranged near the front upper end of the first chamber 131a so that the first chamber 131a can accommodate more humidification water, thereby reducing the number of water replenishment times, avoiding users from frequently replenishing water, and improving the user experience.

[0059] Furthermore, the bottom of the guide plate 130 gradually extends upward from front to back, so that the position of the second chamber 131b is higher than that of the first chamber 131a, which is conducive to the humidification water in the second chamber 131b to flow more smoothly into the first chamber 131a.

[0060] In this embodiment, a first water level sensor 201 is provided in the first chamber 131a, and the first water level sensor 201 is used to detect the water level in the first chamber 131a during the atomization process. The first water level sensor 201 can be arranged along the height direction of the first chamber 131a, so as to enable the user to know the water level in the first chamber 131a, so as to perform the water replenishment operation in time.

[0061] Furthermore, a second water level sensor 202 is provided in the second chamber 131b, and the second water level sensor 202 is used to detect the water level in the second chamber 131b during the water filling process. The second water level sensor 202 can be arranged along the length direction of the second chamber 131b, so as to enable the user to know the water level of the humidification water in the second chamber 131b during the water filling process, and prevent the humidification water from overflowing from the water filling hole 132.

[0062] The atomizing air supply assembly 140 may include an atomizing sheet 141 and a fan 142, wherein the atomizing sheet 141 may be disposed at the bottom of the water storage chamber 131, and is mainly used to atomize the humidification water, thereby forming water mist in the water storage chamber 131. The fan 142 may be disposed at the top of the water storage chamber 131, and is mainly used to blow air toward the mist outlet hole 133, thereby blowing the water mist in the water storage chamber 131 out of the mist outlet hole 133.

[0063] When the water storage chamber 131 is divided into a first chamber 131a and a second chamber 131b by a partition plate 134, the atomizing sheet 141 should be arranged on the bottom wall of the first chamber 131a. The atomizing sheet 141 is used to atomize the humidification water in the first chamber 131a, and the fan 142 blows the atomized water mist out of the first chamber 131a through the mist outlet hole 133.

[0064] In this embodiment, the fan 142 may be composed of a motor 191 and a fan, wherein the motor 191 is located at the rear side of the partition plate 134, the fan is located at the front side of the partition plate 134, and the output shaft of the motor 191 is fixedly connected to the rotating shaft 171 of the fan. In practical applications, waterproof measures may be taken for the motor 191 to prevent the motor 191 from being damaged by water. The waterproof measures may be in various forms, such as adding a waterproof cover, etc., and this embodiment does not specifically limit this.

[0065] When the bottom of the guide plate 130 gradually extends upward from front to back so that the position of the second chamber 131b is higher than the position of the first chamber 131a, the atomizer sheet 141 is preferably arranged adjacent to the front side of the first chamber 131a. This ensures that the atomizer sheet 141 is immersed in the humidification water and reduces the risk of damage to the atomizer sheet 141 due to dry burning.

[0066] The front wall (i.e., the front side wall) of the guide plate 130 can be gradually tilted downward from the back to the front, and the mist outlet hole 133 vertically penetrates the front wall of the guide plate 130. In this way, the water mist formed in the water storage chamber 131 can be blown out toward the front and upward through the mist outlet hole 133, which is beneficial for the air conditioner indoor unit 10 to send the water mist to the far end of the room during the air outlet process, thereby reducing the humidity difference between different areas of the room.

[0067] The distance between adjacent mist outlet holes 133 should be no less than 5 cm. For example, the distance between adjacent mist outlet holes 133 may be 5 cm, 10 cm, 20 cm, etc. If the distance between adjacent mist outlet holes 133 is too small, the structural strength of the front wall of the guide plate 130 will be reduced, affecting the structural stability of the guide plate 130.

[0068] The mist outlet hole 133 may be composed of a plurality of water outlet micropores arranged in a dispersed manner. The water outlet micropores may be circular holes, square holes, triangular holes, elliptical holes, etc. Of course, the mist outlet hole 133 may also be composed of a combination of water outlet micropores of various shapes. By designing the mist outlet hole 133 as a plurality of water outlet micropores arranged in a dispersed manner, the outflow speed of the water mist can be increased, ensuring that the water mist can be carried to the far end of the room during the air outlet process of the air conditioner indoor unit 10.

[0069] In this embodiment, each water outlet micro-hole is a circular hole, one of which is located at the center, and the other water outlet micro-holes are arranged around the water outlet micro-hole. In this way, the aesthetics of the front side of the guide plate 130 can be improved to a certain extent.

[0070] According to any one of the above optional embodiments or a combination of multiple optional embodiments, the embodiments of the present invention can achieve the following beneficial effects:

[0071] The air conditioner indoor unit 10 of the embodiment of the present invention has a first connecting arm 150 and a second connecting arm 160 extending downward at both ends of its housing 110, and a flow guide plate 130 is arranged between the first connecting arm 150 and the second connecting arm 160. A water storage chamber 131 for storing humidification water is formed inside the flow guide plate 130, and a water adding hole 132 and a mist outlet hole 133 communicating with the water storage chamber 131 are provided. Since the first end of the flow guide plate 130 is hinged to the first connecting arm 150, and a locking device 180 is provided between the second end of the flow guide plate 130 and the second connecting arm 160, during the water replenishment process, the lock on the second end of the flow guide plate 130 can be released, and then the flow guide plate 130 can be rotated downward around its first end as a whole, so that the water adding hole 132 on the flow guide plate 130 is at a lower position, and the user can directly add humidification water to the water storage chamber 131 without standing at a high place, which greatly reduces the difficulty of water replenishment and improves the safety and convenience of water replenishment operation.

[0072] Furthermore, in the air conditioner indoor unit 10 of the embodiment of the present invention, a partition plate 134 is provided in the water storage chamber 131, and the partition plate 134 divides the interior of the water storage chamber 131 into a first chamber 131a and a second chamber 131b arranged front to back. The first end of the partition plate 134 has a water outlet 135 connecting the first chamber 131a and the second chamber 131b, the water adding hole 132 is arranged at the top of the second chamber 131b, and the mist outlet 133 is arranged at the front side of the first chamber 131a. In this way, during the water replenishment process, the humidification water replenished through the water adding hole 132 will be temporarily stored in the second chamber 131b. After the second end of the guide plate 130 is lifted back to its original position, the humidification water can gradually flow from the second chamber 131b to the first chamber 131a through the water outlet 135, which effectively avoids the problem of the humidification water flowing out of the mist outlet 133 during the water replenishment process, which is conducive to the smooth progress of the water replenishment operation.
