Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and more specifically, to an air conditioner. Background Art

[0002] During the operation of an air conditioner, especially when the heating function is used in winter, the indoor air often becomes dry. Excessively dry air can make people feel uncomfortable, and generally users will use an air humidifier together. To better meet the needs of users and improve the functionality of the air conditioner, an air conditioner with a humidifying function has become a development direction of air conditioners.

[0003] To meet the above needs, some air conditioner products with a humidifying function have also appeared in the existing market. One method is to use a waterless humidifying module, which usually needs to be used in conjunction with the fresh air function, has a large volume, and the humidifying capacity is affected by the external air humidity. Another method is to use water humidification. The existing water humidification generally integrates the humidifying component on one side of the indoor unit alone, resulting in a small humidifying area of the humidifying module and unable to well meet the humidifying needs. Summary of the Utility Model

[0004] The problem solved by the utility model is that the water humidifying module of the existing air conditioner is arranged on one side of the air conditioner, and the humidifying and moisture delivery ranges are small, and it cannot well meet the humidifying needs of users.

[0005] To solve the above problems, the present application provides an air conditioner that can better achieve humidification to meet the humidifying needs of users.

[0006] The utility model provides an air conditioner, which includes an indoor unit body, a water tank assembly and a wet film assembly. The indoor unit body is provided with a water tank installation cavity and an air outlet duct;

[0007] The water tank assembly is installed in the water tank installation cavity;

[0008] An assembly groove communicated with the air outlet duct is arranged on the front side of the indoor unit body, and the wet film assembly is installed in the assembly groove;

[0009] The water tank assembly is connected to the wet film assembly through a pipeline, and the water tank assembly can supply water to the wet film assembly.

[0010] In the present application, the water tank assembly is installed in the water tank installation cavity provided in the indoor unit body, and the film assembly is installed in the assembly groove communicated with the air outlet duct. In this way, the water tank assembly can supply water to the wet film assembly through the pipeline, and the air sent out by the air outlet duct of the air conditioner can take away the moisture on the wet film assembly after passing through the wet film assembly. In this way, the humidified air can be sent over a long distance by means of the air supply ability of the air conditioner, thereby increasing the humidifying range, and there is no need to add a separate heating and air supply component for the wet film assembly, which can save space and cost.

[0011] In an alternative embodiment, the air conditioner further includes a telescopic assembly;

[0012] The water tank installation cavity has an opening facing downward;

[0013] The top of the telescopic assembly is installed in the water tank installation cavity and is fixedly connected to the indoor unit body;

[0014] The bottom of the telescopic assembly is connected to the water tank assembly;

[0015] The water tank assembly has a water supply position accommodated in the water tank installation cavity and a water filling position moved out of the water tank installation cavity through the opening;

[0016] The telescopic assembly can move the water tank assembly between the water filling position and the water supply position.

[0017] In this application, by providing a telescopic assembly and connecting the water tank assembly to the indoor unit body using the telescopic assembly, the purpose of this setting is that when the water tank assembly needs to be filled with water, the telescopic assembly can be extended by pulling the water tank assembly downward, so that the water tank assembly can be moved downward from the opening out of the water tank installation cavity to the water filling position, which is more convenient. After the water tank assembly is filled with water, the water tank assembly can be pushed upward to make the water tank assembly received in the water supply position in the water tank installation cavity, making it more convenient to fill the water tank assembly.

[0018] In an alternative embodiment, the water tank assembly is provided with a downwardly extending pull rod, and the water tank assembly can be pulled downward and pushed upward through the pull rod.

[0019] Since the indoor unit of the air conditioner is generally installed at a relatively high height, it is generally out of reach of the user standing on the ground. When filling the water tank assembly with water, the user needs to use a climbing device to pull the water tank assembly downward from the opening out of the water tank installation cavity, which is a relatively troublesome process and results in a poor user experience. In this application, by providing a downwardly extending pull rod for the water tank assembly, when the water tank assembly needs to be filled with water, the user can directly pull the water tank assembly downward to the water filling position by pulling the pull rod while standing on the ground. After the water tank assembly is filled with water, the user uses the pull rod to push the water tank assembly upward to install it in the water supply position in the water tank installation cavity through the opening. The entire water filling process does not require the use of a climbing device, and the user experience is better.

[0020] In an alternative embodiment, the water tank assembly is provided with a mounting groove, and the pull rod is installed in the mounting groove. The pull rod has a retracted state received in the mounting groove and an extended state extending out of the mounting groove. When the pull rod is in the extended state, the pull rod extends downward.

[0021] In this application, by providing an installation groove in the water tank assembly, the pull-down rod can be accommodated in the installation groove during seasons when the air conditioner does not use the humidification function, making the air conditioner more aesthetically pleasing. And during seasons when the air conditioner uses the humidification function, the pull-down rod is then unfolded downward to facilitate the user to pull downward and push upward the water tank assembly when adding water.

[0022] In an alternative embodiment, the pull-down rod includes a first section and a second section connected at an angle; the installation groove includes a receiving groove and two clamping grooves provided on both sides in the height direction of the receiving groove. The bottom wall of the clamping groove at the bottom is provided with an extending hole; the pull-down rod is installed in the receiving groove. When the pull-down rod is in the extended state, the end of the second section away from the first section extends out of the extending hole, and the first section is clamped in the clamping groove below the receiving groove; when the pull-down rod is in the unfolded state, at least a part of the second section is received in the receiving groove, and the first section is clamped in the clamping groove above the receiving groove.

The side wall of the installation groove is provided with a first clamping hole and a second clamping hole at intervals in the height direction, and the first clamping hole is located above the second clamping hole. The telescopic pull rod is installed in the installation groove, and the clamping component is arranged at the top end of the telescopic pull rod. When the telescopic pull rod is in the storage state, the clamping component is clamped in the first clamping hole. When the telescopic pull rod is in the unfolded state, the clamping component is clamped in the second clamping hole. The unlocking component is arranged at the bottom end of the telescopic pull rod and extends to the clamping component. Pressing the unlocking component can drive the clamping component to retract into the telescopic pull rod.

[0027] With the shapes of the pull-down rods with the above different structures provided by this application, the storage of the pull-down rod can be conveniently achieved.

[0028] In an alternative embodiment, the water tank assembly includes a water tank and a water tank tray.

[0029] The pull-down rod is arranged on the water tank tray, and the water tank is detachably installed on the water tank tray.

[0030] This application provides a water tank and a water tank tray for the water tank assembly, which can conveniently achieve the disassembly of the water tank to facilitate adding water to and cleaning the water tank.

[0031] In an alternative embodiment, the air conditioner further includes a locking component. The locking component is arranged in the water tank installation cavity and is configured to fix the water tank assembly at the water supply position in the water tank installation cavity. The locking component can also be unlocked under the action of an external force to release the fixation of the water tank assembly.

[0032] This application is provided with a latch assembly, so that the water tank assembly can be stably fixed at the water supply position in the water tank installation cavity, preventing the water tank assembly from falling from the opening. When it is necessary to pull down the water tank assembly, the latch assembly can be conveniently unlocked by an external force, making it more convenient to use.

[0033] In an alternative embodiment, the latch assembly includes a rebounder, which is installed on the side wall of the opening. A lock hole is provided on the side wall of the water tank assembly. When the telescopic assembly is in the shortened state, the telescopic rod of the rebounder can be inserted into the lock hole. A guiding inclined surface is provided on the periphery below the lock hole. When the water tank assembly moves upward, the guiding inclined surface can push the telescopic rod of the rebounder to move, so that the telescopic rod of the rebounder extends out and is inserted into the lock hole or retracts into the mounting seat of the rebounder.

[0034] and / or,

[0035] The latch assembly includes a ball pressing rebounder. The telescopic assembly has multiple sections of guide rails. The top section of the guide rail of the telescopic assembly is connected to the indoor unit body, and the bottom section of the guide rail is connected to the water tank tray. One of the ball and the rebounding base of the ball pressing rebounder is installed on the top section of the guide rail, and the other is installed on the bottom section of the guide rail. When the multiple sections of guide rails are in the shortened position, the ball can be clamped in the rebounding base. Pushing the water tank assembly upward can release the clamping of the rebounding base on the ball.

[0036] This application uses a rebounder or a ball pressing type rebounder for the latch assembly, making the unlocking of the latch assembly more convenient. When unlocking, only pushing the water tank assembly upward can achieve unlocking, which is easy to operate.

[0037] In an alternative embodiment, the air conditioner further includes a mounting seat and a water pump;

[0038] The mounting seat is fixedly installed in the water tank installation cavity. The mounting seat is provided with a water pump bracket extending downward. The water pump is installed on the water pump bracket, and the water pump is connected to the wet film assembly through a pipeline;

[0039] The water tank assembly has an upward water filling port;

[0040] When the water tank assembly is in the water supply position, the water pump bracket is inserted into the water tank assembly through the water filling port;

[0041] When the water tank assembly is in the water filling position, the water pump bracket is removed from the water tank assembly through the water filling port and is located above the water tank assembly.

[0042] In the present application, the water pump bracket is arranged on the mounting base, and the water filling port of the water tank assembly is upward. When the water tank assembly moves downward, the water pump bracket can be moved out of the water tank as the water tank assembly moves downward. During the installation process of pushing the water tank assembly upward, the water pump bracket is inserted into the water tank assembly through the water filling port as the water tank assembly moves upward. Overall, during the entire water filling process, the user does not need to disassemble and assemble the water pump, making the operation simpler and more convenient.

[0043] In an alternative embodiment, the wet film assembly includes a wet film, a wet film bracket, and a mounting bracket;

[0044] The wet film is installed on the wet film bracket;

A water tank and a water inlet communicating with the water tank are provided on the top of the mounting bracket. A plurality of water dropping holes are provided along the length direction of the water tank;

[0046] The pipeline is connected to the water inlet;

[0047] In the present application, by setting the wet film assembly as a wet film, a wet film bracket, and a mounting bracket, the installation and disassembly of the wet film bracket can be conveniently realized, and the wet film can be conveniently disassembled, assembled, and cleaned. A water tank and a water inlet connected to the water tank are provided on the top of the mounting bracket, so that the pipeline connected to the water tank assembly can supply water to the water tank. The water in the water tank can drop onto the wet film of the wet film bracket through the water dropping holes, thereby realizing the humidification of the wet film.

[0048] In an alternative embodiment, a water receiving groove is provided on the lower side of the wet film bracket, and a water outlet hole communicating with the water receiving groove is provided;

[0049] The mounting bracket is provided with a water guiding groove and a drain port;

[0050] The water outlet hole communicates with the water guiding groove, and the drain port is used to connect a drain pipe.

[0051] Since the humidifying water dropping from the water dropping holes onto the wet film may be excessive, the excessive water can be received in the water receiving groove by providing a water receiving groove on the wet film bracket. A water guiding groove and a drain joint are provided in the middle frame, and the water receiving groove communicates with the water guiding groove through the water outlet hole. In this way, the water in the water receiving groove can flow into the water guiding groove through the water outlet, and then be discharged to the water receiving tray or outside the indoor unit through the drain pipe connected to the drain joint. The purpose of providing the water guiding groove is that when replacing the wet film, the wet film bracket needs to be removed, and with the current setting, the drain joint is arranged on the mounting bracket, so there is no need to remove the external drain pipe when disassembling the wet film bracket, which is more convenient.

[0052] In an alternative embodiment, the air conditioner further includes a panel. The panel is installed on the indoor unit body, and an avoidance notch or a plurality of air outlet micro-holes are provided at the position of the panel corresponding to the assembly groove.

[0053] In this application, an avoidance notch is provided on the panel, so that the wet film component can be cleaned without removing the panel. And a number of air outlet micropores are provided at the position of the panel corresponding to the assembly groove, allowing the humidified air to flow out, thus achieving zero air feeling.

[0054] In an alternative embodiment, the air conditioner further includes a buffer spring. One end of the buffer spring is connected to the water tank assembly, and the other end is connected to the indoor unit body.

[0055] In this application, by providing a buffer spring, buffering can be carried out during the downward movement of the water tank assembly, enabling the water tank assembly to descend slowly. Description of the Drawings

Detailed implementation mode

[0079] In existing air conditioners with water humidification, the humidification component is generally integrated separately on one side of the indoor unit, resulting in a relatively small humidification area of the humidification module and unable to well meet the humidification needs of users.

[0080] This embodiment provides an air conditioner that can better achieve humidification to meet the humidification needs of users.

[0081] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be made in conjunction with the accompanying drawings.

[0082] Please refer to Figures 1 to 3 and Figure 20, the air conditioner 100 includes an indoor unit body 110, a water tank assembly 130, and a wet film assembly 170. The indoor unit body 110 is provided with a water tank installation cavity 111 and an air outlet duct 115. The cross-flow fan of the indoor unit body 110 can send air into the room along the air outlet duct 115. The water tank assembly 130 is installed in the water tank installation cavity 111. An assembly groove 117 communicating with the air outlet duct 115 is provided on the front side of the indoor unit body 110, and the wet film assembly 170 is installed in the assembly groove 117. The water tank assembly 130 and the wet film assembly 170 are connected by a pipeline (not shown in the figure), and the water tank assembly 130 can supply water to the wet film assembly 170.

[0083] In this embodiment, the water tank assembly 130 is installed inside the indoor unit body 110, and the wet film assembly 170 is installed in the assembly groove 117 provided on the front side of the indoor unit body 110 and communicating with the air outlet duct 115. In this way, the water tank assembly 130 can supply water to the wet film assembly 170 through the pipeline, and the air sent out by the cross-flow fan of the air conditioner 100 from the air outlet duct 115 can pass through the wet film assembly 170 to take away the moisture on the wet film assembly 170. In this way, the humidified air can be sent over a long distance by means of the air supply capacity of the cross-flow fan of the air conditioner 100, thereby increasing the humidification range. And since when the air conditioner 100 is in heating operation, hot air is sent to the wet film assembly 170, there is no need to add a separate heating device and air supply component for the wet film assembly 170, saving space and cost.

[0084] It should be noted that the air conditioner 100 is a wall-mounted air conditioner 100, and the indoor unit body 110 is an important component of the indoor unit of the air conditioner 100. Generally, the indoor unit body 110 includes a base, a middle frame, a cross-flow fan, a wind deflector, a heat exchanger, and a panel 330. The cross-flow fan and the heat exchanger are installed on the base. The middle frame is installed on the base and encloses the outside of the cross-flow fan and the heat exchanger. The panel 330 is installed on the front of the middle frame. The indoor unit body 110 is provided with an air outlet (not marked in the figure) communicating with the air outlet duct 115. The wind deflector is installed at the air outlet, and when the cross-flow fan operates, air can be sent from the air outlet duct 115 to the air outlet and the wet film assembly 170. And a panel air duct will be formed between the middle frame and the panel 330 of the indoor unit body 110. The panel air duct is connected to the air outlet duct 115. When the cross-flow fan operates, air can be sent to the air outlet duct 115, and then flow from the air outlet duct 115 to the panel air duct, and the humidified air is discharged through the wet film assembly 170.

[0085] Generally, the humidification function of the air conditioner 100 is commonly used in winter heating. When the hot air sent out by the cross-flow fan from the air outlet passes through the wet film assembly 170, the water on the wet film assembly 170 can be evaporated and mixed with the air to form humidified air, which is sent to the room by the wet film assembly 170. Since the cross-flow fan has a strong air supply capacity, the hot air humidified by the wet film assembly 170 can flow to a farther distance, thereby realizing large-area humidification.

[0086] Compared with the prior art where an ultrasonic humidifier module is provided on one side of the wall-mounted indoor unit of the air conditioner 100, the air conditioner 100 provided in this embodiment utilizes the strong air supply and heating capabilities of the cross-flow fan, thereby enabling better large-scale humidification.

[0087] It should also be noted that when the air conditioner 100 generally operates in the humidification mode, the air deflector of the indoor unit can be closed so that the air sent by the cross-flow fan can all be humidified by the wet film assembly 170 and then sent into the room. Of course, in some other embodiments of the present application, the air deflector can also be partially opened so that a part of the air sent by the cross-flow fan can be sent out from the air outlet without humidification, and the other part of the air is sent out after being humidified by the wet film assembly 170. In some embodiments, the indoor unit body 110 can also include an upper air deflector and a lower air deflector. During humidification, both the upper air deflector and the lower air deflector can be closed to achieve humidification of all airflows, or the upper air deflector can be rotated inward and the lower air deflector can be rotated outward to achieve partial humidification. Secondly, a number of micropores can also be provided on the air deflector to achieve the effect of zero air feeling, so that part of the air in the air outlet duct 115 is directly sent into the room through the micropores of the air deflector during humidification, and a part is sent into the room after being humidified by the wet film assembly 170. It can be seen that the indoor unit body 110 of the air conditioner 100 provided in this embodiment can be a conventional single air deflector indoor unit, a single air deflector indoor unit with zero air feeling, an upper and lower double air deflector indoor unit, or an inner and outer double air deflector indoor unit. This embodiment does not limit the specific type of the indoor unit body 110, as long as the air sent out from its air outlet duct 115 can at least partially flow towards the wet film assembly 170.

[0088] Please refer to Figures 1 to 3 , in this embodiment, the water tank installation cavity 111 is arranged in the area of the indoor unit body 110 near the left end. The water tank installation cavity 111 has an opening 113 opened downward, that is, the opening 113 is arranged on the bottom wall of the water tank installation cavity 111, that is, the opening 113 is arranged on the bottom wall of the indoor unit body 110. Please refer to Figure 17 , the top of the indoor unit body 110 is provided with an installation opening 119 corresponding to the opening 113. The water tank assembly 130 is installed in the water tank installation cavity 111 through the opening 113, and can be pulled out downward through the opening 113 to add water to the water tank 157 of the water tank assembly 130. Of course, in some other embodiments of the present application, the installation cavity can also be arranged on one side of the right end of the indoor unit body 110.

[0089] Secondly, an observation port (not shown in the figure) is formed on the side wall of the water tank installation cavity 111. The observation port can be formed on the front of the indoor unit body 110 or can also be arranged on the side of the indoor unit body 110. Users can directly observe the water level of the water tank assembly 130 through the observation port.

[0090] Please refer to Figures 1 to 6, Further, the air conditioner 100 further includes a telescopic component 190 and a water pump component 210. The water pump component 210 is fixedly installed in a water tank installation cavity 111 inside the indoor unit body 110, and the water pump component 210 is communicated with the wet film component 170 through a pipeline. The top end of the telescopic component 190 is installed in the water tank installation cavity 111 and is fixedly connected to the indoor unit body 110. The lower end of the telescopic component 190 is fixedly connected to the water tank component 130. The water tank component 130 has a water supply position received in the water tank installation cavity 111 and a water filling position moved out of the water tank installation cavity 111 through an opening 113. The telescopic component 190 can move the water tank component 130 between the water filling position and the water supply position. When the water tank component 130 is in the water supply position, the water pump component 210 can suck the water in the water tank component 130 to the wet film component 170.

[0091] In this embodiment, the water tank component 130 is connected to the indoor unit body 110 through the telescopic component 190. The purpose of this setting is that when the water tank component 130 needs to be filled with water, the telescopic component 190 can be extended by pulling the water tank component 130 downward, and the water tank component 130 can be moved out of the installation cavity through the opening 113. In this way, the water tank component 130 can be conveniently filled with water by moving it downward. After the water tank component 130 is filled with water, the water tank component 130 can be pushed upward to move the water tank component 130 upward through the opening 113 and installed at the water supply position of the installation cavity. The telescopic component 190 can guide during the upward and downward movement of the water tank component 130, so that the water tank component 130 and the opening 113 are kept corresponding in the vertical direction. When the water tank component 130 moves downward to the water filling position, the telescopic component 190 can also provide an upward pulling force on the water tank component 130, without affecting the user to hold the water tank 157. The water pump component 210 is fixedly installed in the water tank installation cavity 111. The water tank component 130 is fixed during the upward and downward movement of the water tank component 130, which can prevent the wire harness of the water pump 213 from being pulled off and also avoid disassembling and assembling the water pump component 210 and the pipeline during the water filling process.

[0092] Please refer to Figures 1 to 6 , as well as Figure 16 and Figure 17 , Further, the water pump component 210 includes a mounting seat 211 and a water pump 213. The mounting seat 211 is fixedly installed in the water tank installation cavity 111, and the mounting seat 211 is provided with a water pump bracket 215 extending downward. The water pump 213 is installed at the bottom of the water pump bracket 215. The water pump 213 is connected to the wet film component 170 through a pipeline. The water tank component 130 has an upward water filling port 131. Please refer to Figure 4 , when the water tank component 130 is in the water supply position, the water pump bracket 215 is inserted into the water tank component 130 through the water filling port 131. Please refer to Figure 5, when the water tank assembly 130 is in the water filling position, the water pump bracket 215 is moved out of the water tank assembly 130 from the water filling port 131 and is located above the water tank assembly 130. That is, when the user pulls down the water tank assembly 130 to the water filling position, the water pump bracket 215 will be separated from the water tank assembly 130 as the water tank assembly 130 moves downward, and the water pump assembly 210 will remain fixed in the water tank installation cavity 111 and be separated from the water tank assembly 130. After the user fills the water tank assembly 130 with water, during the process of pushing up the water tank assembly 130, since the water pump assembly 210 corresponds to the water filling port 131 of the water tank assembly 130, as the water tank assembly 130 rises, the water pump bracket 215 will gradually be inserted into the water tank assembly 130 from the water filling port 131 until the bottom of the water pump bracket 215 extends to the bottom of the water tank assembly 130 when the water tank assembly 130 is lifted to the water supply position, realizing the combination of the water pump assembly 210 and the water tank assembly 130.

[0093] In this embodiment, the water pump bracket 215 of the mounting base 211 is installed in the mounting cavity through the mounting opening 119 opened at the top of the mounting cavity. That is, it is installed in the mounting cavity from top to bottom. The mounting base 211 is fixedly connected to the top wall of the indoor unit body 110 by bolts. The pipeline connecting the water pump 213 and the wet film assembly 170 is fixed through the inner side wall of the indoor unit body 110 to connect the two.

[0094] Please refer to Figure 5 , in this embodiment, the mounting base 211 includes a top plate 217 and side plates 219 provided on both sides of the top plate 217. The water pump bracket 215 is centrally arranged in the gap between the two side plates 219, and gaps are formed between the two sides of the water pump bracket 215 and the two side plates 219 respectively. When the water tank assembly 130 is installed in the water supply position in the mounting cavity, the water pump bracket 215 is inserted into the water tank assembly 130, and the two side plates 219 are located outside the water tank assembly 130 and on both sides in the width direction.

[0095] Furthermore, a water tank cover 221 is provided on the water pump bracket 215. When the water tank assembly 130 is installed in the mounting cavity and is in the water supply position, the water tank cover 221 covers the water filling port 131 of the water tank assembly 130 to prevent dust and the like from falling into the water tank assembly 130.

[0096] Secondly, in some other embodiments of the present application, the water tank cover 221 can also be movably installed on the water pump bracket 215. For example, a through hole is dug in the middle of the water tank cover 221 so that the bottom end of the water pump bracket 215 passes through the through hole of the water tank cover 221, and a limiting part is arranged below the water pump bracket 215 where it is located on the water tank cover 221, enabling the water tank cover 221 to move up and down. During the downward movement of the water tank assembly 130, the water tank cover 221 will also move downward under the action of gravity until it abuts against the limiting part and stops. When the water tank assembly 130 moves upward, the water tank cover 221 abuts against the top of the water tank assembly 130 to seal the water tank 157, and then the water tank cover 221 will move upward under the push of the water tank assembly 130, thus preventing water from spilling out during the upward movement of the water tank assembly 130. Further, the top of the water tank cover 221 can be set as a groove with a downward concave middle part. When water comes out of the gap where the through hole is combined with the water pump bracket 215, the water will flow back along the side wall of the groove into the water tank 157 body, preventing water from spilling outside.

[0097] Please refer to Figure 17 , further, the water pump assembly 210 further includes a water pump cover 223. The water pump cover 223 is installed on the water pump bracket 215 by a buckle and encloses a water pump chamber 225 with the water pump bracket 215. A hole is arranged at the bottom of the water pump chamber 225. The water pump 213 is installed at the bottom of the water pump chamber 225. A liquid level sensor (not marked in the figure) and a silver ion module (not shown in the figure) are also installed on the water pump bracket 215. The mounting seat 211 and the water pump bracket 215 are integrally formed. During assembly, first install the water pump 213 on the water pump bracket 215, then snap the water pump cover 223 onto the water pump bracket 215 by a buckle, and install the liquid level sensor at a preset position on the water pump bracket 215. Then install the assembled water pump assembly 210 downward through the installation opening 119 into the water tank installation cavity 111.

[0098] In this embodiment, the water pump bracket 215 is arranged on the mounting seat 211 and the water filling port 131 of the water tank assembly 130 faces upward. In this way, when the water tank tray 159 drives the water tank 157 to move downward, as the water tank assembly 130 moves downward, the water pump bracket 215 can be moved out of the water tank 157, and no operation on the water pump 213 is required during water filling. During the process of the water tank tray 159 driving the water tank 157 to move upward, the water pump bracket 215 can be directly inserted into the water tank 157 through the water filling port 131, and no operation on the water pump assembly 210 is required either, thus facilitating the disassembly and assembly of the water tank 157.

[0099] In this embodiment, the telescopic assembly 190 is a telescopic guide rail, and there are two sets of telescopic guide rails. The first sections of the two sets of telescopic guide rails are fixedly installed on the outer sides of the two side panels 219 by screws one by one. The bottom sections of the two sets of telescopic guide rails are fixedly installed on both sides of the water tank assembly 130 by screws one by one. In this way, when the water tank tray 159 is pulled downward, the telescopic guide rails are extended to allow the water tank tray 159 to move downward with the water tank 157.

[0100] Please refer to Figure 4 and Figure 5 In this embodiment, the telescopic assembly 190 is a three-section telescopic rail, and the three sections are connected in sequence in the extended state. In the shortened state, the second and third sections can be accommodated in the first section. The length of the telescopic rail after extension is about 60cm. Of course, the length of the telescopic rail after extension can also be selected to be longer or shorter according to needs, so as to ensure that the indoor unit body 110 is installed on the wall and the telescopic rail is in a fully extended state, and the user can conveniently add water to the water tank assembly 130 while standing on the ground.

[0101] Generally, the installation height of the indoor unit of the wall-mounted air conditioner 100 is between 1.8 meters and 2.2 meters, or even higher. Although, in this embodiment, the telescopic assembly 190 is provided so that when the water tank assembly 130 is pulled down to the water adding position, the user can add water to the water tank assembly 130 while standing on the ground. However, since the water tank assembly 130 is installed at a relatively high height from the ground at the water supply position in the water tank installation cavity 111 in the normal use state, it is still not easy for the user to pull down the water tank assembly 130 or push the water tank assembly 130 upward to install it in the water tank installation cavity 111 while standing on the ground. As a result, when the user adds water to the water tank 157, the water tank assembly 130 needs to be pulled down and pushed up with the help of climbing equipment, which affects the user experience.

[0102] In order to solve the problem that the user can pull down the water tank assembly 130 from the water supply position to the water filling position or push the water tank assembly 130 from the water filling position to the water supply position in the installation cavity without the aid of climbing equipment while standing on the ground, please refer to Figure 2 In the present embodiment, the water tank assembly 130 is provided with a downwardly extending pull rod 251 , by which the water tank assembly 130 can be pulled downward and pushed upward.

[0103] In this example, a downwardly extending pull-down rod 251 is provided in the water tank assembly 130. Before adding water to the water tank assembly 130, the user can stand on the ground and pull the water tank assembly 130 down from the opening 113 to the water adding position through the pull-down rod 251. After the water tank assembly 130 is filled with water, the user can stand on the ground and push the water tank assembly 130 upward to the opening 113 through the pull-down rod 251, and the water supply position installed in the installation cavity. The whole process can be achieved without the aid of climbing equipment. Combined with the setting of the water pump assembly 210, when adding water to the water tank assembly 130, it is only necessary to pull down and push up the pull-down rod 251 to move the water tank assembly 130 downward and upward, which makes the process of adding water to the water tank assembly 130 simpler and more convenient overall.

[0104] It should be noted that the downward extension length of the pull-down rod 251 (i.e., the extension length extending from the lower side of the indoor unit) can be set to 20 cm, 30 cm or longer, and can be set according to specific needs to ensure that the user can easily grab the pull-down rod 251 when standing on the ground.

[0105] For example, in one set of data, the installation height of the air conditioner 100 is 2m, and the downward extension distance of the pull-down rod 251 is 20cm, so that the bottom end of the pull-down rod 251 is 1.8m above the ground, and the user can conveniently hold the pull-down rod 251 while standing on the ground. After the water tank assembly 130 moves down to the water filling position, the height of the water tank assembly 130 from the ground is about 1.4m, so that the user can conveniently add water to the water tank 157 while standing on the ground.

[0106] Please refer to Figure 1 2. Further, the water tank assembly 130 is provided with a mounting groove 133, and the pull-down rod 251 is installed in the mounting groove 133. The pull-down rod 251 has a storage state in which it is accommodated in the mounting groove 133 and an extended state in which it extends out of the mounting groove 133. When the pull-down rod 251 is in the extended state, the pull-down rod 251 extends downward.

[0107] Generally, humidification is usually required in the dry winter. In summer, the temperature and humidity are high, and the indoor air is already relatively humid and usually does not need humidification. In this embodiment, a mounting groove 133 is provided in the water tank assembly 130, so that the pull-down rod 251 can be stored in the mounting groove 133 in the season when the humidification function is not used, so as to be more beautiful. In winter or before using the humidification function, the pull-down rod 251 is moved out of the mounting groove 133. If the humidification function is used for a period of time afterwards, the pull-down rod 251 does not need to be stored in the mounting groove 133. Before the humidification function is not used for a long time, the pull-down rod 251 can be stored in the mounting groove 133.

[0108] Of course, in some other embodiments of the present application, the lower pull rod 251 can also be fixedly arranged on the water tank assembly 130. Secondly, some hooks or crossbars can be arranged at the bottom end of the lower pull rod 251 or at intervals in the height direction, so that the lower pull rod 251 can also be used as a clothes hanger.

[0109] Please refer to Figures 6 to 8 , in this embodiment, the lower pull rod 251 includes a telescopic pull rod 253, a clamping component 255 and an unlocking component 257. The side walls of the installation groove 133 are provided with a first clamping hole 135 and a second clamping hole 137 at intervals in the height direction, and the first clamping hole 135 is located above the second clamping hole 137. The telescopic pull rod 253 is installed in the installation groove 133, the clamping component 255 is arranged at the top end of the telescopic pull rod 253. When the telescopic pull rod 253 is in the storage state, the clamping component 255 is clamped in the first clamping hole 135. When the telescopic pull rod 253 is in the unfolded state, the clamping component 255 is clamped in the second clamping hole 137. The unlocking component 257 is arranged at the bottom end of the telescopic pull rod 253 and extends to the clamping component 255. Pressing the unlocking component 257 can drive the clamping component 255 to retract into the telescopic pull rod 253. The overall operation is relatively simple and convenient.

[0110] Please refer to Figure 7 and Figure 9 , further, the clamping component 255 includes a guide post 259, a locking block 261 and a first spring 263. A hollow chamber 265 is arranged in the telescopic pull rod 253, and a side hole 267 communicating with the hollow chamber 265 is arranged on the side wall of the telescopic pull rod 253 near the top end. The guide post 259 is installed in the hollow chamber 265 and corresponds to the side hole 267. The locking block 261 is installed on the guide post 259, and the clamping post on the locking block 261 corresponds to the side hole 267. The first spring 263 is sleeved on the guide post 259 and abuts against the locking block 261. The first spring 263 provides a restoring force for the locking block 261 to move the locking block 261 away from the guide post 259, so that the clamping post extends out of the side hole 267 and is clamped in the first clamping hole 135 or the second clamping hole 137.

[0111] Please refer to Figures 6 to 8, Further, the unlocking component 257 includes a button portion 269, a guiding portion 271, and a second spring 273. The button portion 269 is disposed at the bottom end of the extended pull rod. The second spring 273 abuts against the button portion 269 for resetting the button. The guiding portion 271 is disposed in the hollow chamber 265, and the bottom end of the guiding portion 271 is connected to the button portion 269. The top end of the guiding portion 271 extends to the locking block 261. A first guiding surface 275 is provided at the top end of the guiding portion 271, and a second guiding surface 277 is provided on the locking block 261. The first guiding surface 275 abuts against the second guiding surface 277. Both the first guiding surface 275 and the second guiding surface 277 are inclined surfaces, which can convert the movement of the guiding portion 271 in the vertical direction into the movement of the locking block 261 in the horizontal direction. Pressing the button can compress the second spring 273 and drive the guiding portion 271 to move, thereby driving the locking block 261 to move toward the guiding column 259. After releasing the button, the button and the guiding portion 271 can be reset under the action of the second spring 273, while the locking block 261 can be reset under the action of the first spring 263.

[0112] Please refer to Figure 6 , Further, the telescopic pull rod 253 is U-shaped and includes a first telescopic rod, a second telescopic rod, and a holding portion. The first telescopic rod and the second telescopic rod are oppositely arranged. One end of the holding portion is connected to the lower end of the first telescopic rod, and the other end of the holding portion is connected to the lower end of the second telescopic rod. The water tank assembly 130 is provided with two mounting grooves 133. The first telescopic rod and the second telescopic rod are respectively mounted in the two mounting grooves 133. The button is mounted on the holding portion. There are two clamping components 255, and the two clamping components 255 are respectively mounted on the inner sides of the tops of the first telescopic rod and the second telescopic rod. The guiding portion 271 extends along the interiors of the first telescopic rod and the second telescopic rod to the clamping component 255. The telescopic pull rod 253 provided in this embodiment is a U-shaped telescopic pull rod 253, which can move up and down in the vertical direction, so as to achieve storage and deployment. And when the lower pull rod 251 is in the deployed state, the holding portion can be used to hang clothes.

[0113] Please refer to Figures 9 to 13 , In another embodiment, the lower pull rod 251 includes a first section 285 and a second section 287 connected at an angle. The mounting groove 133 includes a receiving groove 139 and two clamping grooves 141 provided on both sides in the height direction of the receiving groove 139. An extending hole 145 is provided on the bottom wall of the clamping groove 141 at the bottom. The lower pull rod 251 is mounted in the receiving groove 139. When the lower pull rod 251 is in the extended state, the second section 287 away from the first section 285 completely extends out of the extending hole 145, and the first section 285 is clamped in the clamping groove 141 located below the receiving groove 139. When the lower pull rod 251 is in the deployed state, at least a part of the second section 287 is received in the receiving groove 139, and the first section 285 is clamped in the clamping groove 141 located above the receiving groove 139.

[0114] Please refer to Figure 9 and Figure 10 When the lower pull rod 251 needs to be unfolded, the user first rotates the lower pull rod 251 through the extended part of the second section 287 to drive the first section 285 to rotate, so that the first section 285 moves out of the clamping groove 141 located above the receiving groove 139. Please refer to Figure 10 and Figure 11 Then, pull down the lower pull rod 251. When the lower pull rod 251 cannot be pulled (because the first section 285 abuts against the bottom wall of the receiving groove 139), it means that the second section 287 has been fully extended. Please refer to Figure 11 and Figure 12 After that, rotate the lower pull rod 251 again, so that the lower pull rod 251 drives the first section 285 to rotate into the clamping groove 141 located below the receiving groove 139, and the unfolding process of the lower pull rod 251 is completed. When receiving the lower pull rod 251, just perform the reverse operation. Since when the lower pull rod 251 is in the extended state, the first section 285 is clamped in the clamping groove 141 located on the lower side of the receiving groove 139, the lower pull rod 251 will not retract when a downward or upward thrust is applied later. Setting the lower pull rod 251 in this way can meet the requirement of pulling down the water tank assembly 130 and also meet the requirement of pushing up the water tank assembly 130.

[0115] It should be noted that the two clamping grooves 141 arranged on both sides of the receiving groove 139 in the height direction are arranged on the side wall of the receiving groove 139, and as a whole, they form a groove in the shape of an inverted "concave" character after being flipped 90°.

[0116] Please refer to Figures 9 to 13 In this embodiment, the first section 285 and the second section 287 are vertically connected, and the first section 285 is formed by bending the top end of the second section 287. Secondly, the lower pull rod 251 further includes a holding section 289 connected to one end of the second section 287 away from the first section 285. The length of the second section 287 is the same as the height of the receiving groove 139. When the lower pull rod 251 moves up along the receiving groove 139 until the holding section 289 abuts against the bottom wall of the water tank assembly 130, the first section 285 corresponds to the clamping groove 141 located on the upper side of the receiving groove 139 in the height direction. Rotating the lower pull rod 251 can drive the clamping part to be inserted into the clamping groove 141. And when the lower pull rod 251 is in the received state, the second section 287 is received in the receiving groove 139, and only the holding section 289 is exposed. The user can operate the holding section 289 to operate the lower pull rod 251 to make the lower pull rod 251 extend downward.

[0117] Further, the holding section 289 is formed by bending the lower end portion of the lower pull rod 251, and the extending direction of the holding section 289 is the same as or opposite to the extending direction of the first section 285. Making the extending direction of the holding section 289 the same as or opposite to the extending direction of the first section 285 allows the user to determine the orientation of the first section 285 based on the orientation of the holding section 289, so as to determine whether the first section 285 is inserted into the clamping groove 141.

[0118] Please refer to Figure 13 , further, a limiting groove 143 protrudes upward from the top wall of the clamping groove 141 located below the receiving groove 139. When the lower pull rod 251 is in the unfolded state, pushing the lower pull rod 251 upward causes the first section 285 to be clamped in the limiting groove 143. In this way, the limiting groove 143 can restrict the rotation of the lower pull rod 251 when the water tank assembly 130 is pushed upward, and can prevent the rotation of the lower pull rod 251 from affecting the upward pushing of the water tank assembly 130 due to changes in the force direction during the upward pushing process.

[0119] Please refer to Figure 9 , when the lower pull rod 251 is in the stored state, the first section 285 overlaps on the bottom wall of the clamping groove 141 located above the receiving groove 139. The bottom wall of the upper clamping groove 141 bears the weight of the lower pull rod 251, and the lower pull rod 251 will not fall downward. Please refer to Figure Figure 9 and Figure 10 , when the user needs to extend the lower pull rod 251, first rotate the lower pull rod 251 along the axis of the second section 287 so that the first section 285 moves out of the upper clamping groove 141, and the first section 285 is located directly above the receiving groove 139. Please refer to Figure 10 and Figure 11 , then pull the lower pull rod 251 downward. Please refer to Figure 11 and Figure 12 , when the lower pull rod 251 is pulled to the lowest point and cannot be pulled anymore, then rotate the lower pull rod 251 so that the first section 285 rotates into the clamping groove 141 below the receiving groove 139. In this way, when later pushing the tray upward through the lower pull rod 251, the first section 285 is clamped in the receiving groove 139 below the receiving groove 139 and will not move upward. When the user does not use the lower pull rod 251 and needs to store the lower pull rod 251 upward, first rotate the lower pull rod 251 so that the first section 285 rotates to correspond to the receiving groove 139, and then push the lower pull rod 251 upward until the height of the first section 285 is higher than the height of the bottom wall of the upper clamping groove 141, and then rotate the lower pull rod 251 so that the second section 287 is inserted into the upper clamping groove 141.

[0120] Please refer to Figure 14 and Figure 15, in another alternative embodiment, the installation groove 133 is provided on the bottom wall of the water tank assembly 130, the lower pull rod 251 is rotatably installed in the installation groove 133, and the lower pull rod 251 can be turned downward from the storage state to the unfolded state. That is, after the lower pull rod 251 is turned upward, it can fit against the bottom wall of the water tank 157, and after being turned downward, it can extend vertically downward from the bottom wall of the water tank assembly 130.

[0121] Further, the lower pull rod 251 is provided with a rotating portion 291, and the side wall of the installation groove 133 is provided with a plug hole 147. The rotating portion 291 is inserted into the plug hole 147, and the lower pull rod 251 can be turned downward or upward along the axis of the rotating shaft.

[0122] Please refer to Figure 14 and Figure 15 , further, the lower pull rod 251 includes a holding rod 293 and two connecting rods 295. The two connecting rods 295 are arranged oppositely. One end of the holding rod 293 is connected to the end of one connecting rod 295, and the other end of the holding rod 293 is connected to the end of the other connecting rod 295. The side walls of the two connecting rods 295 at the ends away from the holding rod 293 are both provided with rotating shaft portions. The receiving groove 139 includes a first groove section, a second groove section and a third groove section. The first groove section and the second groove section are arranged at intervals. The third groove section is arranged between the first groove section and the second groove section, and the two ends are correspondingly connected to the first groove section and the second groove section respectively. The side walls of the first groove section and the second groove section away from the third groove are both provided with plug holes 147. The two rotating portions 291 are correspondingly inserted into the two plug holes. When the lower pull rod 251 is in the receiving state, the two connecting rods 295 are correspondingly received in the first groove section and the second groove section, and the holding rod 293 is received in the third groove section. That is, the lower pull rod 251 is in a "U" shape, and the installation groove 133 is also a U-shaped groove, so that the holding rod 293 between the two connecting rods can be used for holding and can also be used as a clothes hanger, etc.

[0123] Further, the lower pull rod 251 further includes a support rod 297, and the two ends of the support rod 297 are correspondingly connected to the ends of the two connecting rods 295 away from the holding rod 293. That is, a rectangular frame-shaped lower pull rod 251 is formed. The receiving groove 139 further includes a fourth groove section, the fourth groove section is arranged at intervals with the third groove section, and the two ends of the fourth groove section are correspondingly connected to the ends of the first groove section and the second groove section away from the third groove section respectively. The support rod 297 is installed in the fourth groove section. The installation groove 133 is a rectangular ring groove. The lower pull rod 251 is arranged in this way to make the structure of the lower pull rod 251 more stable.

[0124] Please refer to Figure 5 and Figure 16, in this embodiment, the water tank assembly 130 includes a water tank 157 and a water tank tray 159. The water tank tray 159 includes a bottom plate and a limiting plate. Limiting plates are provided on three sides of the periphery of the bottom plate, and the remaining side is open. The water tank 157 is installed in the water tank 157 assembly cavity 177 formed by enclosing the bottom plate and the limiting plate, and can be removed from the open side. The water filling port 131 of the water tank 157 is opened upward, and the water pump bracket 215 can be directly inserted or removed. When the water tank 157 needs to be filled with water, the water tank 157 can be directly removed to receive water, which is more convenient to use. The lower pull rod 251 is arranged on the water tank tray 159, and the installation groove 133 is also arranged on the water tank tray 159. The lower end of the telescopic guide rail (i.e., the telescopic assembly 190) is connected to the water tank tray 159 by screws.

[0125] Secondly, in some other embodiments, the water tank assembly 130 is also integral. When water needs to be added, the user can directly pour water into the water tank assembly 130 with a container.

[0126] Please refer to Figure 5 and Figure 16 , in this embodiment, the bottom plate of the water tank tray 159 is inclined in the front-back direction and also in the left-right direction. In this way, after the user places the water tank 157 on the bottom plate of the water tank tray 159, the inclination of the bottom plate of the water tank tray 159 will guide the water tank 157 in the front-back direction and left-right direction, so that the water tank 157 moves to the preset position of the water tank tray 159, and the water tank 157 is centered with the water pump assembly 210.

[0127] Please refer to 16. In this embodiment, the air conditioner 100 further includes a latch assembly 310. The latch assembly 310 is arranged in the water tank installation cavity 111. The latch assembly 310 is configured to fix the water tank assembly 130 at the water supply position in the water tank installation cavity 111. The latch assembly 310 can also be unlocked under the action of an external force to release the fixation of the water tank assembly 130.

[0128] In this embodiment, by providing the latch assembly 310, when the water tank tray 159 and the water tank 157 are received in the opening 113, they can be clamped to ensure the stability of the installation.

[0129] When it is necessary to add water to the water tank 157, first unlock the lock component 310, and then pull down the water tank tray 159. The guide rail component extends, and the water tank tray 159 drives the water tank 157 to move downward out of the opening 113, that is, below the indoor unit body 110. Then remove the water tank 157 to add water to the water tank 157, or directly add water to the water tank 157 installed on the water tank tray 159. After adding water, push up the water tank tray 159. The guide rail shortens, and the water tank tray 159 and the water tank 157 can be received at the water supply position in the water tank installation cavity 111 through the opening 113 and then fixed by the lock component 310. The guide rail component can guide during the lifting and lowering process of the water tank tray 159 to align the water tank tray 159 with the opening 113 and move stably. Secondly, after the water tank tray 159 is pulled down, the telescopic guide rail can also provide an upward pulling force to the water tank tray 159, facilitating the user to add water to the water tank 157.

[0130] Please refer to Figure 16 , in an embodiment, the lock component 310 includes a ball pressing and rebounding device 313. The telescopic component 190 is a multi-section telescopic guide rail. One section of the guide rail at the top of the telescopic component 190 is connected to the mounting seat 211, and one section of the guide rail at the bottom is connected to the water tank tray 159. One of the ball and the rebounding base of the ball pressing and rebounding device 313 is installed on the top section of the guide rail, and the other is installed on the bottom section of the guide rail. When the multi-section guide rail is in the shortened position, the ball can be clamped in the rebounding base. Pushing up the water tank component 130 can release the clamping of the rebounding base to the ball.

[0131] In this embodiment, the ball pressing and rebounding device 313 is adopted, and the installation is simple and convenient. During use, pushing up the water tank tray 159 drives the bottom section of the guide rail of the telescopic component 190 to move upward, causing the ball to be clamped or separated from the rebounding base, making the use simpler.

[0132] It should be noted that the ball pressing and rebounding device 313 is also called a beetle self-locking device, which is a common hardware fitting and can achieve the clamping and unlocking between the ball and the rebounding base by pressing.

[0133] Of course, in some embodiments of the present application, one of the ball and the rebounding base of the ball pressing and rebounding device 313 can also be installed on the mounting seat 211, and the other can be installed on the water tank tray 159.

[0134] Generally, two groups of ball pressing and rebounding devices 313 are installed, corresponding to two groups of telescopic guide rails respectively. In this way, the clamping can be more stable.

[0135] Please refer to Figure 17 and Figure 18, in another embodiment, the latch assembly 310 includes a bumper 315 which is horizontally installed on the side wall of the water tank mounting cavity 111. A lock hole 161 is provided on the side wall of the water tank tray 159. When the telescopic assembly 190 is in the shortened state, the telescopic rod of the bumper 315 can be inserted into the lock hole 161 (i.e., when the water tank tray 159 and the water tank 157 are received in the water supply position of the water tank mounting cavity 111, the lock hole 161 is aligned with the position of the bumper 315). A guide block 163 is provided on the lower peripheral edge of the lock hole 161, and the guide block 163 has an inclined guide slope 165. The movement of the water tank tray 159 can cause the guide slope 165 to push the telescopic rod of the bumper 315 to move in the direction of retracting into the mounting seat 211 of the bumper 315, so that the telescopic rod of the bumper 315 extends and is inserted into the lock hole 161 or retracts and moves out of the lock hole 161.

[0136] The buckle assembly of this embodiment adopts a bumper 315, and a lower insertion groove and a guide slope 165 are provided on the tray of the water tank 157. By pushing up the water tank tray 159, the telescopic rod of the bumper 315 can be extended or retracted, which is convenient for the user to operate. The installation is also relatively convenient, and only the bumper 315 needs to be installed at the corresponding position on the side wall of the water tank mounting cavity 111.

[0137] In this embodiment, two bumpers 315 are installed, which are respectively installed on the left and right side walls of the water tank mounting cavity 111 and extend horizontally outwards.

[0138] It should be noted that the bumper 315 is also called a rod-type bumper 315 and a telescopic-rod-type bumper 315, which is a device that uses a telescopic rod structure to achieve a rebound function. Generally, it includes: a telescopic rod: usually composed of two or more inner and outer sleeves, and the inner rod can be telescoped in the outer rod. The rod body is usually made of metal or high-strength plastic to ensure sufficient strength and stability. A spring: built inside the telescopic rod to provide the elastic force required for rebound or slow closing. The spring can be a helical spring, a torsion spring or a gas spring, etc. A locking mechanism: a locking device is provided at a certain section of the telescopic rod, usually including a buckle, a friction plate or a magnetic device, used to lock when the telescopic rod extends to a specific position to prevent accidental retraction. A trigger device: used to transmit the external pressing or pulling force to trigger the telescopic action of the telescopic rod. The inner rod of its telescopic rod generally has an extended state and a retracted state, and can be maintained at these two positions. When the telescopic rod is axially pushed to compress the telescopic rod, the telescopic rod can be converted from the telescopic state to the shortened state and maintained. When the telescopic rod in the shortened state is axially pushed, it can extend to the telescopic state under the action of the spring.

[0139] Please refer to Figure 16, in this embodiment, when the telescopic rod of the ejector 315 is inserted into the lock hole 161, the telescopic rod is also in contact with the guiding inclined surface 165. When water needs to be added to the water tank 157, the user pushes the water tank tray 159 upward. During this process, as the water tank tray 159 moves upward, the guiding inclined surface 165 also moves upward, causing the telescopic rod of the ejector 315 to be compressed and move out of the lock hole 161, and remain in the shortened state. Then, when the user pulls the water tank tray 159 downward, the water tank tray 159 and the water tank 157 can be pulled out from the opening 113. After adding water, when the user pushes the water tank tray 159 upward, the guiding inclined surface 165 compresses the telescopic end of the ejector 315 again. The compressed telescopic rod can extend under the action of the spring and be inserted into the lock hole 161 to realize the clamping of the water tank tray 159. The principle of the push-type ejector 315 is similar to that of a push-type cylindrical pen. It can be extended by the first push and retracted by the second push.

[0140] In this embodiment, by setting the lock assembly 310 as the above two types of ejectors 315, when the user needs to unlock and lock, it can be achieved by simply pushing upward. Combined with the setting of the pull rod 251, the user can stand on the ground and achieve unlocking and locking through the pull rod 251.

[0141] Furthermore, the air conditioner 100 further includes a buffer spring (not shown in the figure). One end of the buffer spring is connected to the water tank assembly 130, and the other end is connected to the indoor unit body 110. Specifically, the top end of the buffer spring can be fixed to the mounting seat 211, and the lower end is mounted on the water tank tray 159. Of course, it can also be that the top end of the buffer spring is directly connected to the side wall of the water tank installation cavity 111 (i.e., the top end is fixed to the indoor unit body 110), and the bottom end can be fixed to the water tank tray 159.

[0142] In this embodiment, by setting the buffer spring, buffering can be carried out during the downward movement of the water tank assembly 130, so that the water tank assembly 130 can slowly descend.

[0143] Please refer to Figures 19 to 22 , in this embodiment, the wet film assembly 170 includes a wet film 171, a wet film frame 173, and a mounting frame 175. The wet film 171 is installed in the wet film frame 173. The mounting frame 175 is installed in the assembly groove 117. An assembly cavity 177 is provided on the front side of the mounting frame 175. A water tank 179 and a water inlet (not marked in the figure) communicating with the water tank 179 are provided at the top of the mounting frame 175. A plurality of water dropping holes 183 are provided along the length direction of the water tank 179. A pipeline is connected to the water inlet. The wet film frame 173 is installed in the assembly cavity 177, and the water dropping holes 183 are located above the wet film frame 173. The water pump 213 pumps water into the water tank 179. After flowing evenly in the water tank 179, it will drop from the water dropping holes 183 onto the wet film 171 of the wet film frame 173, thus realizing the humidification of the wet film 171.

[0144] In this embodiment, the wet film assembly 170 is installed with the wet film holder 173 by setting up the mounting bracket 175, which facilitates the installation and disassembly of the wet film holder 173 when cleaning and replacing the wet film 171. A water tank 179 and a water inlet connected to the water tank 179 are provided at the top of the mounting bracket 175. Thus, the pipeline connected to the water pump 213 can supply water to the water tank 179, and the water in the water tank 179 can fall onto the wet film 171 of the wet film holder 173 through the water dropping holes 183, thereby realizing the humidification of the wet film 171.

[0145] Further, the mounting bracket 175 is snap-fitted into the assembly groove 117 on the front side of the indoor unit body 110. The wet film holder 173 is also installed in the assembly cavity 177 from the front side of the mounting bracket 175 by snap-fitting. When disassembling the wet film holder 173, it can be removed from the front side of the indoor unit. The water inlet is provided in the middle of the water tank 179 in the length direction.

[0146] In this embodiment, a water receiving tank 185 is provided on the lower side of the wet film holder 173, and a water outlet hole 187 communicating with the water receiving tank 185 is provided. The mounting bracket 175 is provided with a water guiding tank 189 and a drain port 191 communicating with the water guiding tank 189. A drain joint is provided at the drain port 191. After the wet film holder 173 is installed on the mounting bracket 175, the water outlet hole 187 communicates with the water guiding tank 189. The drain joint is connected with a drain pipe. The drain pipe communicates with the water receiving tray of the indoor unit. In some embodiments, the drain pipe also directly leads to the outside of the indoor unit to drain the water to the outside.

[0147] Since there may be excess humidification water dropping from the water dropping holes 183 onto the wet film 171, the excess water can be received in the water receiving tank 185 by providing the water receiving tank 185 on the wet film holder 173. A water guiding tank 189 and a drain joint are provided in the middle frame, and the water receiving tank 185 communicates with the water guiding tank 189 through the water outlet hole 187. Thus, the water in the water receiving tank 185 can flow into the water guiding tank 189 through the water outlet, and then be drained to the water receiving tray or outside the indoor unit through the drain pipe connected to the drain joint. The purpose of providing the water guiding tank 189 is that when replacing the wet film 171, the wet film holder 173 needs to be removed. With the drain joint set on the mounting bracket 175 in this way, it is more convenient to disassemble the wet film holder 173 without removing the external drain pipe.

[0148] Of course, in some other embodiments of the present application, the lower end surface of the wet film holder 173 can also be set to be through, so that the excess water can directly flow into the water guiding tank 189.

[0149] Please refer to Figure 19, in this embodiment, the air conditioner 100 further includes a panel 330. The panel 330 is installed on the front side of the indoor unit body 110. The panel 330 is provided with an avoidance notch 331 corresponding to the position of the assembly groove 117, so that the wet film holder 173 is exposed outside. In this way, when the wet film holder 173 is disassembled, it can be disassembled without removing the panel 330.

[0150] Certainly, in some embodiments of the present application, a number of air outlet micro-holes may also be provided on the panel 330 corresponding to the position of the assembly groove 117 to achieve the zero-wind-sensation delivery of the humidifying air flow.

[0151] In summary, the air conditioner 100 provided in this embodiment can conveniently achieve water humidification and has a large humidification range. Most importantly, when adding water to the water tank 157, the water tank tray 159 and the water tank 157 can be conveniently pulled down by the lower pull rod 251. After adding water, the water tank assembly 130 can be pushed and installed by the lower pull rod 251 again, and the water in the water tank 157 can be conveniently added without borrowing high-altitude equipment.

[0152] Although the present utility model is disclosed as above, the present utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the scope defined by the claims.
