[0044] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings in conjunction with the embodiments. DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0047] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0048] The present invention provides an air-conditioning indoor unit, which can realize automatic cleaning of an evaporator, so as to simplify the cleaning method of the evaporator and facilitate users to clean the evaporator.

[0049] See also Figure 1 and Figure 2 In the first embodiment of the air conditioner indoor unit 100 of the present invention, the air conditioner indoor unit 100 includes a housing 110, an evaporator 120 installed in the housing 110, and a water receiving tray 150. The air conditioner indoor unit 100 also includes a water washing device 200 (not shown) installed in the housing 110; the water washing device 200 is arranged adjacent to the evaporator 120, the water washing device 200 is connected to the water source 300 through a first pipeline, and the water washing device 200 is connected to the water receiving tray 150 through a second pipeline to clean the evaporator 120.

[0050] Specifically, the housing 110 is provided with an air inlet 111, an air outlet 112, and an air path connecting the air inlet 111 and the air outlet 112, and the evaporator 120 and the wind wheel 130 are sequentially arranged in the wind path. The evaporator 120 is arranged in a multi-fold shape, so that the evaporator 120 surrounds the wind wheel 130 in a semi-enclosed shape. When the air conditioner indoor unit 100 is working, the wind wheel 130 rotates to drive the air flow to enter from the air inlet 111, and after being filtered by the filter 170 (such as filtering dust and sterilizing), it enters the interior of the housing 110, and the air flow exchanges heat with the evaporator 120 to form an outlet air flow. Driven by the wind wheel 130, the outlet air flow is blown to the air outlet 112 through the air path, and finally blown to the room through the air outlet 112, so as to achieve cooling or heating of the indoor environment.

[0051] The water washing device 200 may include one or more combinations of a spray assembly, a roller brush assembly or other structures with a water washing function. And the water washing device 200 may be one or more. When multiple water washing devices 200 are arranged in the shell 110, the multiple water washing devices 200 can be arranged along the circumference of the evaporator 120 to wash different positions of the evaporator 120. The water source 300 and the water receiving tray 150 are respectively connected to the water washing device 200 through two independent pipelines. The first pipeline and the second pipeline are independent and do not interfere with each other, which can avoid water pollution in the two pipelines. It should be noted that the water source 300 can be an external water source such as a water tank or a water bottle installed on the shell 110, or an external water source such as a water tank or a water bottle provided by the user to the air conditioner indoor unit 100. Specific details will be introduced later.

[0052] According to the technical solution of the present invention, the water source 300 and the water receiving tray 150 are respectively connected to the water washing device 200 through two independent pipelines, wherein the water in the water source 300 can be supplied to the water washing device 200 through the first pipeline; and the water in the water receiving tray can be supplied to the water washing device 200 through the second pipeline, so as to realize the recycling of the water in the water receiving tray 150. The first pipeline and the second pipeline are independent and do not interfere with each other, which can avoid water pollution in the two pipelines. When the water in the water receiving tray 150 becomes dirty, the water washing device 200 is replaced with cleaner water in the water source 300 to clean the evaporator 120, thereby improving the utilization of water resources and the water washing efficiency. It can be seen that the air conditioner indoor unit 100 in this embodiment allows the user to arbitrarily select any one or both of the water receiving tray 150 and the water source 300 to supply water to the water washing device 200.

[0053] It is worth mentioning that when the water washing device 200 washes the wind wheel 130, it can also moisten the air, especially when the water of the water washing device 200 contacts the evaporator 120, this part of the water exchanges heat with the evaporator 120 to generate water vapor, and the water vapor is mixed into the air, which also has the effect of humidifying the air. It can be seen that the air conditioner indoor unit 100 of the present invention can not only wash the evaporator 120 with water to achieve the effect of improving the cleanliness of the evaporator 120, but also humidify the air to improve the air humidity, thereby greatly improving the air quality of the air outlet of the air conditioner indoor unit 100.

[0054] See also Figure 1 and Figure 2In this embodiment, the water washing device 200 is arranged above the evaporator 120. Since the evaporator 120 is arranged in a multi-fold shape, the evaporator 120 surrounds the wind wheel 130 in a semi-enclosed shape. Therefore, the water washing device 200 can be arranged between the front side of the evaporator 120 and the front panel of the shell 110; or, the water washing device 200 is arranged between the rear side of the evaporator 120 and the back plate of the shell 110; or, the water washing device 200 is arranged between the top of the evaporator 120 and the air inlet 111. Considering that the air inlet surface (heat exchange surface) on the front side of the evaporator 120 is larger, more air will enter through the air inlet surface on the front side of the evaporator 120. Therefore, preferably, the water washing device 200 can be located between the front side of the evaporator 120 and the front panel of the shell 110 to fully wash the air and increase the amount of air washed. In addition, there may be multiple water washing devices 200, and the multiple water washing devices 200 surround the evaporator 120 in a circumferential direction to increase the area of ​​the water washing evaporator 120 and improve the water washing efficiency.

[0055] See also Figure 2 In this embodiment, the first pipeline is provided with a first water pump 10a, and the washing device 200 draws water from the water source 300 through the first water pump 10a. Obviously, the first water pump 10a is not necessary, and the first water pump 10a can be provided by the user. Alternatively, the second pipeline can also be provided with a second water pump 10b, and the washing device 200 draws water from the water receiving tray through the second water pump 10b. In addition, in other embodiments, the first water pump 10a can also be provided in the first pipeline, and the second water pump 10b can also be provided in the second pipeline.

[0056] See also Figure 3 In order to realize the multiple recycling of water in the washing device 200 to improve the water utilization rate, preferably, the washing device 200 is connected to the water source 300 through a circulation pipeline. A circulation valve 30 is provided on the circulation pipeline. By opening the circulation valve 30, the water in the washing device 200 can be discharged into the water source 300 and then discharged to the outside through the water source 300.

[0057] See also Figure 4 In the second embodiment of the present invention, based on any of the above embodiments, the surface of the housing 110 is provided with an installation opening that docks with the opening of the water source 300. The docking can be plug-in, threaded connection, or buckle connection, which is not specifically limited here.

[0058] See also Figure 4Here, considering that the air conditioner indoor unit 100 is usually installed on a higher wall, the user needs to climb up with the aid of a ladder or a chair to install the water source 300 to the installation port. At this time, it is inconvenient for the user to turn on the water washing device 200 to absorb water from the water source 300. Therefore, preferably, a micro switch 400 adjacent to the installation port is provided in the housing 110, and the micro switch 400 is connected to the water washing device 200, and is used to trigger the water washing device 200 to absorb water from the water source 300 when the water source 300 is installed at the installation port.

[0059] See also Figure 4 The micro switch 400 is relatively common in the current market. The micro switch 400 applies force to the action reed through a transmission element (a pin, a button, a lever, a roller, etc.). When the action reed is displaced to a critical point, an instantaneous action is generated, so that the moving contact at the end of the action reed is quickly connected or disconnected with the fixed contact. When the force on the transmission element is removed, the action reed generates a reverse action force. When the reverse stroke of the transmission element reaches the action critical point of the reed, the reverse action is completed instantaneously. Therefore, when the water bottle 500 extends into the housing 110 from the installation port, the water bottle 500 triggers the micro switch 400, so that the micro switch 400 triggers the washing device 200 to absorb water from the water source 300. When the water bottle 500 moves out of the housing 110 from the installation port, the force of the water bottle 500 on the micro switch 400 is released, the micro switch 400 is reset, and the washing device 200 stops sucking water from the water source 300.

[0060] See also Figure 4 In addition, in other embodiments, a detection device (not shown) for detecting whether the water source 300 is installed in the installation port may be provided in the housing 110. The detection device includes a detector, an indicator, and a controller connected to the detector and the indicator. When the detector detects that the water source 300 is installed in the installation port, a detection signal is transmitted to the controller. The controller receives the detection signal and controls the indicator to issue an indication message according to the detection signal. After the indicator issues the indication message, the user can control the washing device 200 to absorb water from the water source 300 by means of a switch button or a remote controller. The indicator may be an indicator light, a voice prompter, or an alarm, which is not limited here.

[0061] See also Figure 5 and Figure 6In the third embodiment of the present invention, the water source 300 is a water storage device detachably mounted on the housing 110. Considering that the air conditioner indoor unit 100 is usually mounted on a higher wall, the user needs to climb up with the aid of a ladder or a chair or other tools to disassemble and assemble the water storage device and add water to it, and the water adding operation is difficult. In order to facilitate the user to disassemble and assemble the water storage device, preferably, the water storage device includes a water tank 310, a support rod 320 movably mounted on the water tank 310 in the up-down direction, and a driving device 330 connected to the support rod 320, and the driving device 330 is used to drive the support rod 320 to extend downward to the bottom of the water tank 310.

[0062] Specifically, the water storage device can be installed at the bottom or end of the housing 110. In order to reduce the space occupied by the water storage device below the room, it is preferred to install the water storage device at the end of the housing 110. The support rod 320 can be connected to the water tank 310 through the groove rail matching structure. When it is necessary to add water to the water tank 310, the support rod 320 is driven downward by the driving device 330. The user does not need to use tools such as ladders and chairs to climb up. The water tank 310 can be added with water by simply holding the support rod 320 to remove the water tank 310. After the water is added, the user installs the water tank 310 back to the housing 110 by holding the support rod 320, and then drives the support rod 320 upward through the driving device 330.

[0063] There is no limitation on the structure of the driving device 330, and the driving device 330 is only required to be able to drive the support rod 320 to move in a straight line in the vertical direction. For example, the driving device 330 includes two gears and two motors, and racks are provided on two opposite sides of the support rod 320. The two gears are provided on both sides of the support rod 320 and mesh with the racks on the support rod 320. The two motors are connected to the two gears respectively, and the motor drives the two gears to rotate, thereby clamping and driving the support rod 320 to move in a straight line in the vertical direction.

[0064] See also Figure 7 In the fourth embodiment of the present invention, the difference from the third embodiment is that the air conditioner indoor unit 100 further includes a lifting mechanism 500 installed on the base of the housing 110 for lifting the water source 300; the base of the housing 110 is provided with a lifting port for the lifting mechanism 500 to pass through. It should be noted that the water source 300 can be a water tank, a water bottle, etc. fixedly or detachably installed on the lifting mechanism 500, or a water tank or a water bottle provided by the user.

[0065] See also Figure 7When it is necessary to supply water to the washing device 200, the user controls the lifting mechanism 500 to descend from the lifting port to the bottom of the air-conditioning indoor unit 100, and the user places the water source 300 on the lifting mechanism 500; then the lifting mechanism 500 is raised and retracted into the air-conditioning indoor unit 100. In this way, the user can supply water to the washing device 200 without the help of tools such as ladders and chairs. As for the specific structure of the lifting mechanism 500, there is no specific limitation. For example, the lifting mechanism 500 can be a lifting frame including a turntable, a traction line, a lifting motor, and a water supply source 300. The lifting motor is connected to the turntable, one end of the traction line is wound on the turntable, and the other end of the traction line is connected to the lifting frame. The lifting motor drives the turntable to rotate, and releases or reels the traction line, thereby realizing the lifting of the lifting frame.

[0066] See also Figure 8 In the fifth embodiment of the present invention, the difference from the fourth embodiment is that, in order to facilitate the user to supply water to the washing device 200, the water inlet port 220 of the washing device 200 is arranged on the housing 110, and the water inlet port 220 is connected to the water source 300 through a pipeline. Since the water inlet port 220 is arranged on the housing 110, the user can connect the water inlet port 220 and the water source 300 through a pipeline with a handle 40, so that the user can connect the water source 300 placed on the ground with the washing device 200 without the aid of a ladder or a chair or other climbing tool.

[0067] See also Fig. 9 In the sixth embodiment of the present invention, the difference from any of the above embodiments is that the water washing device 200 includes a water inlet pipe 210 for connecting to the water source 300; the air conditioner indoor unit 100 also includes a hose reel 700 installed in the shell 110 and used to wind the water inlet pipe 210.

[0068] Specifically, the hose reel 700 can be installed at any position in the housing 110, such as the end or bottom of the housing 110, as long as the housing 110 is provided with a corresponding outlet for the water inlet pipe 210 to enter and exit. Preferably, the hose reel 700 is installed at the bottom of the housing 110, and the bottom of the housing 110 is provided with a corresponding outlet for the water inlet pipe 210 to enter and exit. When the hose reel 700 releases the water inlet pipe 210, the water inlet pipe 210 extends downward from the outlet. By adjusting the length of the water inlet pipe 210 extending downward, the water source 300 placed at any position (such as on the ground) and the water washing device 200 can be connected. When the water supply is finished, the water inlet pipe 210 can be retracted by the hose reel 700, without the need for the user to climb up with the help of tools such as ladders and chairs.

[0069] There are many types of hose reels 700. For example, see Fig.10 and Fig.11 In a structural design of the hose reel 700, the hose reel 700 includes a box body 710, a driving wheel 720 installed in the box body 710, a driven wheel 730 and a hose reel motor (not shown); wherein the box body 710 is provided with an opening open downward; the driving wheel 720 and the driven wheel 710 are respectively arranged at two opposite sides of the opening for cooperating to clamp the water inlet pipe 210; the hose reel motor is connected to the driving wheel 720 to drive the driving wheel 720 to drive the driven wheel 730 to rotate, and then the driving wheel 720 and the driven wheel 730 clamp the water inlet pipe 210 and move it downward to extend out of the opening, or move it upward to be accommodated back into the box body 710. Please refer to Figure 12-A and Figure 12-B The reel motor drives the active wheel 720 to drive the driven wheel 730 to rotate, so that the water inlet pipe 210 extends downward to ensure that the water inlet pipe 210 extends under the water surface of the water bottle 500; and after the water supply is completed, the reel motor drives the active wheel 720 to drive the driven wheel 730 to rotate in the opposite direction, and the water inlet pipe 210 moves upward and is retracted from the opening to prevent dust from entering the water inlet pipe 210 and reduce pollution.

[0070] See also Fig.13 14 , in another structural design of the hose reel 700 , the hose reel 700 includes a box body 710 and a hose reel shaft 740 and a hose reel motor installed in the box body 710 , wherein the box body 710 is provided with an opening open downward; the hose reel shaft 740 is rotatably installed in the box body 710 for winding the water inlet pipe 210 ; the hose reel motor is connected to the hose reel shaft 740 to drive the hose reel shaft 740 to rotate and drive the water inlet pipe 210 to be wound on the hose reel shaft 740 or released from the hose reel shaft 740 . Figure 14-A and Figure 14-B As shown, when the hose reel 700 is working, the hose reel motor drives the hose reel shaft 740 to rotate, so that the water inlet pipe 210 is released from the rotating shaft 740 and extends downward from the opening; and after the water supply is completed, the hose reel shaft 740 rotates in the opposite direction so that the water inlet pipe 210 is wound around the rotating shaft 740 and retracted from the opening.

[0071] See also Fig.15 In another structural design of the hose reel 700, the hose reel 700 includes a rotatable hose reel 750 and an elastic reset component connected to the hose reel 750, wherein the elastic reset component is used to accumulate elastic potential energy when the hose reel 750 rotates, and to push the hose reel 750 to rotate in the opposite direction by releasing the elastic potential energy; the water inlet pipe 210 is wound around the hose reel 750, and the water inlet end of the water inlet pipe 210 is provided with a hand-held structure for a user to hold, and the hand-held structure extends to the outside of the shell 110.

[0072] When the user needs to add water to the washing device 200, the handheld structure 600 is used to pull the water inlet pipe 210, and the water inlet pipe 210 drives the hose reel 750 to rotate, so that the elastic reset component accumulates elastic potential energy. At this time, the water inlet pipe 210 extends out of the shell 110, and the water inlet pipe 210 can be connected to a lower external water source 300; when the elastic reset component releases the elastic potential energy, it pushes the hose reel 750 to rotate in the opposite direction, so that the water inlet pipe 210 is rolled back onto the hose reel 750, and then accommodated back into the inner side of the shell 110.

[0073] It is worth noting that the handheld structure 600 (see Fig.17 ) A part of the water inlet pipe 210 itself, that is, the lower end of the water inlet pipe 210 can form the hand-held structure 600. Alternatively, the hand-held structure 600 can be any one of a pull rope, a pull rod and a hanging piece connected to the lower end of the water inlet pipe 210, so that the hand-held structure 600 extends downward from the outlet, and can also play the role of a hanging piece decoration.

[0074] See also Figures 15 to 17 Based on the above embodiment, the hose reel 700 further includes a box body 710, a hose reel 750 is rotatably mounted in the box body 710, and a ratchet 760 is provided at one end of the hose reel 750, and a braking ratchet 762 and a reset groove 761 are provided on the periphery of the ratchet 760 for docking with the clamping claw 790. The elastic reset assembly includes a clamping claw 790, a rewinding spring 780 and a reset spring 770; wherein the clamping claw 790 is pivotally connected to the inner wall of the box body 710 for docking with the braking ratchet 762 and the reset groove 761; one end of the rewinding spring 780 is connected to the hose reel 750, and the other end of the rewinding spring 780 is fixed in the box body 710; one end of the reset spring 770 is connected to the clamping claw 790, and the other end of the reset spring 770 is fixed in the box body 710.

[0075] To facilitate explanation of the working principle of the manual hose reel 700, the two brake ratchets 762 are defined as the first brake ratchets 762a and the second brake ratchets 762b, and the two reset grooves 761 are defined as the first reset groove 761a and the second reset groove 761b. When the manual hose reel 700 is working, the user pulls the water inlet pipe 210 downward, the water inlet pipe 210 drives the turntable 750 to rotate, the reset spring 770 and the rewind spring 780 both accumulate elastic potential energy, the claw 790 rotates relatively from the first reset groove 761a to the first brake ratchets 762a, at this time, the water inlet pipe 210 is released, the claw 790 is stuck on the first brake ratchets 762a or the second brake ratchets 762b, the turntable 750 cannot be reversed, and the user can connect the water inlet pipe 210 to the external water source 300 located on or near the ground. When the water supply is finished, the user pulls the water inlet pipe 210 downwards again, and the water inlet pipe 210 drives the turntable 750 to continue to rotate until the claw 790 enters the first reset groove 761a or the second reset groove 761b, and then releases the water inlet pipe 210. The reset spring 770 and the rewinding spring 780 release the elastic potential energy, so that the claw 790 breaks free from the restraint of the first braking ratchet 762a or the second braking ratchet 762b, and rewinds to its original state, and the water inlet pipe 210 is retracted into the box body 710.

[0076] Of course, the structure of the resetting elastic component is not limited to the above one. Figures 15 to 17 The resetting elastic component includes a rewinding spring 780, one end of which is connected to the hose reel 750, and the other end of which is fixed in the box body 710. When water needs to be added to the washing device 200, the user can pull the water inlet pipe 210 downward, and the water inlet pipe 210 drives the hose reel 750 to rotate, so that the water inlet pipe 210 extends below the housing 110. After the water inlet pipe 210 can be connected to the external water source 300, the user keeps pulling the water inlet pipe 210, and the rewinding spring 780 accumulates elastic potential energy. When the water is added, the user releases the water inlet pipe 210, and the rewinding spring 780 automatically releases the elastic potential energy and pushes the hose reel 750 to rotate in the opposite direction, so that the water inlet pipe 210 is wound back on the hose reel 750, so that the water inlet pipe 210 is retracted to the inner side of the housing 110. The structure of the hose reel 700 is relatively simple and easy to manufacture.

[0077] In the above three structural designs of the hose reel 700, the first two structural designs can both turn on the hose reel motor by a switch button; or remotely control the controller by a remote control terminal such as a remote controller or a mobile phone, so that the user can remotely turn on or off the hose reel 700. The latter structural design requires the user to manually pull the hose reel 750 of the hose reel 700. In actual applications, users can select the corresponding one according to market demand and cost, which is not limited here.

[0078] See also Fig.18 Based on any of the above embodiments, it is also considered that the water in the washing device 200 will become dirty after multiple washings, which is inconvenient to continue using. Therefore, in this embodiment, the air conditioner indoor unit further includes a drainage assembly 800, and the drainage assembly 800 connects the washing device 200 and the water receiving tray 150. The drainage assembly 800 includes a drainage pipe connecting the washing device 200 and the water receiving tray 150, and a drainage valve arranged on the drainage pipe. When the water in the washing device 200 becomes dirty, the drainage valve is opened to drain the dirty water in the washing device 200 into the drainage groove of the water receiving tray 150, and then drain outward through the drainage hole of the drainage groove.
