Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a water tank device and an air conditioner. Background Art

[0002] When air conditioners are running, especially when using the heating function in winter, the indoor air tends to become dry. Excessively dry air can make people feel uncomfortable, so most users use humidifiers in conjunction with them. To better meet user needs and improve the functionality of air conditioners, air conditioners with humidification functions have become a development trend.

[0003] However, since the indoor unit of an air conditioner is typically installed at a relatively high height, adding water to the humidification module requires climbing up, which is inconvenient. To avoid this need for climbing up to add water, conventional techniques typically employ an electric drive structure to raise and lower the water tank, allowing the tank to be lowered during refilling and then raised afterward. The electric drive structure for raising and lowering the water tank employs either a motor-driven pulley that retracts and releases a pull cord, or a motor-driven foldable and retractable structure (e.g., a scissor frame) that raises and lowers the water tank.

[0004] Regardless of whether the above two methods are used, they require a motor and an actuator to implement. The motor and actuator will inevitably take up a lot of space, resulting in an increase in the size of the indoor unit, a decrease in the size of the water tank, and an increase in cost. Therefore, how to conveniently add water to the water tank installed in the indoor unit has become a technical problem that needs to be solved in this field. Utility Model Content

[0005] The problem solved by the utility model is how to better realize the addition of water to a water tank installed in an indoor unit.

DETAILED DESCRIPTION

[0089] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0090] Please refer to Figures 1 to 3 The air conditioner 300 includes an indoor unit 310, a water tank assembly 100, and a humidifying assembly 330. The indoor unit 310 is provided with a water tank mounting cavity 311 having a downward-facing mounting notch 313. The water tank assembly 100 is mounted within the mounting cavity 311, and the humidifying assembly 330 is mounted on the indoor unit 310. The water tank assembly 100 and the humidifying assembly 330 are connected by a pipe, and the water tank assembly 100 can supply water to the humidifying assembly 330.

[0091] It should be noted that the indoor unit 310 is a wall-mounted indoor unit 310, which is used to process indoor air, such as heating, cooling, humidification, etc. The wall-mounted indoor unit 310 generally includes a base, a middle frame, a panel 321, a cross-flow fan, an air guide plate and a heat exchanger. The cross-flow fan and the heat exchanger are installed on the base. The middle frame is installed on the base and enclosed on the outside of the cross-flow fan and the heat exchanger. The indoor unit 310 is provided with an air outlet duct 315 and an air outlet for supplying air to the outside. The air outlet is installed on the air guide plate. When the cross-flow fan is running, air can be supplied to the room through the air outlet duct 315.

[0092] In this embodiment, the water tank installation cavity 311 is located in an area near the left end of the indoor unit 310. A mounting notch 313 is defined in the bottom wall of the water tank installation cavity 311. Specifically, the bottom wall of the indoor unit 310 is provided with a mounting notch 313 corresponding to the water tank installation cavity 311. The top of the indoor unit 310 is provided with a mounting opening corresponding to the mounting notch 313. The water tank assembly 100 is installed within the water tank installation cavity 311 via the mounting notch 313 and can be pulled downward through the mounting notch 313 to refill the water tank 149 of the water tank assembly 100. Of course, in other embodiments of the present application, the water tank installation cavity 311 may also be located on the right side of the indoor unit 310.

[0093] Please refer to Figures 1 to 5 In this embodiment, the water tank device 100 includes a water tank assembly 130, a telescopic assembly 110, and a lower pull rod 170. The water tank assembly 130 is used to store water for humidification. The lower end of the telescopic assembly 110 is connected to the water tank assembly 130, and the upper end of the telescopic assembly 110 is mounted within the water tank mounting cavity 311 of the indoor unit 310 via a mounting notch 313. When the telescopic assembly 110 is shortened, the water tank assembly 130 is accommodated within the water tank mounting cavity 311. When the telescopic assembly 110 is extended, the water tank assembly 130 can be moved downwardly out of the water tank mounting cavity 311 through the mounting notch 313. Overall, the water tank assembly 130 has a water supply position, where it is accommodated within the water tank mounting cavity 311, and a water filling position, where it is moved downwardly out of the water tank mounting cavity 311 through the mounting notch 313. The telescopic assembly 110 allows the water tank assembly 130 to move between the water filling and water supply positions. The telescopic assembly 110 can also guide the water tank assembly 130 during the lifting process, and ensure the stable lifting of the water tank assembly 130 to prevent the water tank assembly 130 from shaking during the lifting process. The pull-down rod 170 is provided on the water tank assembly 130 and extends downward to pull down or push up the water tank assembly 130.

[0094] This embodiment provides the water tank assembly 130 with a telescopic assembly 110. The telescopic assembly 110 guides and stabilizes the water tank assembly 130 during the raising and lowering process, preventing the water tank assembly 130 from shaking during the raising and lowering process. Typically, the installation height of a wall-mounted indoor unit 310 is between 1.8 meters and 2.2 meters, or even higher. This embodiment also provides a downwardly extending pull-down rod 170 on the water tank assembly 130. When adding water to the water tank assembly 130, the user can stand on the ground and pull down the pull-down rod 170 to add water. After adding water, the user can push the water tank assembly 130 up and install it in the water tank installation cavity 311 using the pull-down rod 170. Throughout the entire process of adding water to the water tank assembly 130, the user does not need to climb to a height. Furthermore, the water tank assembly 130 does not require a motor or actuator for both the raising and lowering processes, thereby saving space and cost. Overall, the water tank assembly 130 can be set large enough in the case of limited space in the water tank installation cavity 311, thereby increasing the capacity of the water tank assembly 130.

[0095] It should be noted that the downward extension length of the pull-down rod 170 (i.e. the extension length extending from the lower side of the indoor unit 310) 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 170 when standing on the ground.

[0096] For example, in one data set, the indoor unit 310 is installed at a height of 2 meters, and the pull-down rod 170 extends downward by 20 centimeters. Thus, the lowest point of the pull-down rod 170 is 1.8 meters above the ground. A user standing on the ground can conveniently grasp the pull-down rod 170 and pull down the water tank assembly 130. After the water tank assembly 130 is pulled down to the water filling position, it descends to a suitable height above the ground, allowing the user to conveniently add water to the water tank assembly 130 while standing on the ground.

[0097] Please refer to Figure 6 Furthermore, the water tank assembly 130 is provided with a mounting groove 133, and the pull-down rod 170 is mounted in the mounting groove 133. The pull-down rod 170 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 170 is in the extended state, the pull-down rod 170 extends downward.

[0098] Generally, humidification is usually needed in the dry winter. In the summer, the temperature is high and the humidity is high, and the indoor air is already relatively humid, so humidification is usually not required. In this embodiment, a mounting groove 133 is provided in the water tank assembly 130, so that the pull-down rod 170 can be stored in the mounting groove 133 during the season when the humidification function is not used, thereby making it more beautiful. In winter or before using the humidification function, the pull-down rod 170 is moved out of the mounting groove 133. If the humidification function is used for a period of time thereafter, the pull-down rod 170 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 170 can be stored in the mounting groove 133. The indoor unit 310 can also be installed so that the pull-down rod 170 is always in the expanded state.

[0099] Of course, in some other embodiments of the present application, the pull-down rod 170 can also be fixedly arranged on the water tank assembly 130. Secondly, some hooks or cross bars can be arranged at the bottom end of the pull-down rod 170 or at intervals in the height direction, so that the pull-down rod 170 can also be used as a clothes hanger.

[0100] In this embodiment, the lower pull rod 170 includes a telescopic pull rod assembly, the mounting groove 133 is set along the height direction of the water tank assembly 130, the telescopic pull rod assembly is installed in the mounting groove 133, and the telescopic pull rod 171 of the telescopic pull rod assembly can extend downward from the mounting groove 133.

[0101] In this embodiment, the lower pull rod 170 is configured as a telescopic pull rod assembly, thereby facilitating storage and deployment.

[0102] Please refer to Figures 6 to 9 In this embodiment, the telescopic rod assembly includes a telescopic rod 171, a coupling assembly 173, and an unlocking assembly 175. The sidewalls of the mounting slot 133 are spaced apart in the vertical direction with a first coupling hole 135 and a second coupling hole 137, with the first coupling hole 135 located above the second coupling hole 137. The telescopic rod 171 is mounted within the mounting slot 133. The coupling assembly 173 is located at the top of the telescopic rod 171. When the telescopic rod 171 is in the stowed position, the coupling assembly 173 engages with the first coupling hole 135. When the telescopic rod 171 is in the deployed position, the coupling assembly 173 engages with the second coupling hole 137. The unlocking assembly 175 is located at the bottom end of the telescopic rod 171 and extends to the coupling assembly 173. Pressing the unlocking assembly 175 drives the coupling assembly 173 to retract the telescopic rod 171. The lower rod 170 provided in this embodiment can be extended and retracted in the vertical direction, making it more convenient to stow and deploy.

[0103] Furthermore, the clamping assembly 173 includes a guide post 177, a locking block 179, and a first spring 181. A hollow chamber 183 is provided in the telescopic rod 171, and a side hole 185 is provided on the side wall of the telescopic rod 171 near the top, which is connected to the hollow chamber 183. The guide post 177 is installed in the hollow chamber 183 and is provided corresponding to the side hole 185. The locking block 179 is installed on the guide post 177, and the clamping post provided on the locking block 179 corresponds to the side hole 185. The first spring 181 is sleeved on the guide post 177 and abuts against the locking block 179. The first spring 181 is used to provide a restoring force to the locking block 179, causing the locking block 179 to move away from the guide post 177, so that the clamping post of the locking block 179 extends out of the side hole 185 and is clamped to the first clamping hole 135 or the second clamping hole 137.

[0104] Please continue to refer to Figures 6 to 9 Furthermore, the unlocking assembly 175 includes a button portion 187, a guide portion 189 and a second spring 191. The button portion 187 is arranged at the bottom end of the telescopic pull rod 171. The second spring 191 abuts against the button portion 187, and is used to reset the button portion 187 and the guide portion 189. The guide portion 189 is arranged in the hollow chamber 183, and the bottom end of the guide portion 189 is connected to the button portion 187. The top end of the guide portion 189 extends to the locking block 179. A first guide surface 193 is provided at the top end of the guide portion 189. The locking block 179 is provided with a second guide surface 195, and the first guide surface 193 abuts against the second guide surface 195. The first guide surface 193 and the second guide surface 195 are both inclined surfaces, which can convert the vertical movement of the guide portion 189 into the horizontal movement of the locking block 179. Pressing the button portion 187 can compress the second spring 191 and drive the guide portion 189 to move and drive the locking block 179 to move and retract toward the guide column 177, thereby achieving unlocking.

[0105] Please continue to refer to Figures 6 to 9 Furthermore, the telescopic rod 171 is U-shaped and includes a first telescopic rod, a second telescopic rod and a gripping portion. The first telescopic rod and the second telescopic rod are arranged opposite to each other, one end of the gripping portion is connected to the lower end of the first telescopic rod, and the other end of the gripping 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 mounted in the two mounting grooves 133 in a one-to-one correspondence. The button portion 187 is mounted on the gripping portion. There are two snap-fit assemblies 173, and the two snap-fit assemblies 173 are mounted in a one-to-one correspondence on the inner side of the top ends of the first telescopic rod and the second telescopic rod. The guide portion 189 extends along the inside of the first telescopic rod and the second telescopic rod to the snap-fit assembly 173. The telescopic rod 171 provided in this embodiment is a U-shaped telescopic rod 171 with a more stable structure, and after the lower pull rod 170 is pulled down, the user can also hang clothes on the gripping portion.

[0106] Please refer to Figures 10 to 14 In another embodiment, the lower pull rod 170 includes a first section 197 and a second section 199 connected at an angle. The mounting slot 133 includes a receiving slot 139, a first engaging slot 141, and a second engaging slot 143. The first engaging slot 141 is provided at the upper end of the receiving slot 139 and is located on one side in the width direction of the receiving slot 139. The side of the first engaging slot 141 close to the receiving slot 139 is connected to the receiving slot 139. The second engaging slot 143 is provided at the lower end of the receiving slot 139 and is located on one side in the width direction of the receiving slot 139. The side of the second engaging slot 143 close to the receiving slot 139 is connected to the receiving slot 139. The bottom wall of the receiving slot 139 is provided with an extension hole 147. When the lower pull rod 170 is in the extended state, the second section 199 extends downwardly out of the extension hole 147, and the first section 197 is engaged with the second engaging slot 143. When the lower pull rod 170 is in the retracted state, the second section 199 is at least partially received in the receiving groove 139 , and the first section 197 is engaged with the first engaging groove 141 .

[0107] In this embodiment, the receiving slot 139 is configured as described above. To deploy the lower rod 170, the user first rotates the lower rod 170 via the lower end of the second section 199, causing the first section 197 to rotate, allowing the first section 197 to be pulled out of the first engaging slot 141. The user then pulls the lower rod 170 downward. When the lower rod 170 stops moving (due to the first section 197 abutting the bottom wall of the receiving slot 139), the second section 199 is fully extended. The lower rod 170 is then rotated again, causing it to rotate with the first section 197 until it is within the second engaging slot 143, completing the deployment of the lower rod 170. When deploying the lower rod 170, the corresponding operation can be performed. Since the first section 197 is engaged in the first engaging slot 141 when the lower rod 170 is deployed, further upward force applied to the lower rod 170 prevents it from retracting. As a whole, the pull-down rod 170 provided in this application can both pull the water tank assembly 130 downward and push the water tank assembly 130 upward.

[0108] It should be noted that the first clamping groove 141 and the second clamping groove 143 arranged on both sides of the receiving groove 139 in the height direction are arranged on the side walls of the receiving groove 139, and the whole forms a "concave" shaped groove that is flipped 90°.

[0109] Please refer to Figures 10 to 14In this embodiment, the first section 197 and the second section 199 are vertically connected, and the first section 197 is formed by bending the top end of the second section 199. Secondly, the lower rod 170 also includes a gripping section 201 connected to the end of the second section 199 away from the first section 197. The length of the second section 199 is the same as the height of the receiving slot 139. When the lower rod 170 moves up along the receiving slot 139 until the gripping section 201 abuts the bottom wall of the water tank assembly 130, the first section 197 and the first engaging slot 141 are aligned in height. Rotating the lower rod 170 can drive the first section 197 to insert into the first engaging slot 141. When the lower rod 170 is in the retracted state, the second section 199 is contained within the receiving slot 139, with only the gripping section 201 exposed. The user can operate the gripping section 201 to operate the lower rod 170, causing it to extend downward.

[0110] Furthermore, the gripping section 201 is formed by bending the lower end portion of the lower pull rod 170. The extending direction of the gripping section 201 is the same as or opposite to the extending direction of the first section 197. By making the extending direction of the gripping section 201 the same as or opposite to the extending direction of the first section 197, the user can determine the orientation of the first section 197 by the orientation of the gripping section 201, and thus determine whether the first section 197 is inserted into the first insertion slot and the second insertion slot.

[0111] Furthermore, a stopper groove 145 protrudes upward from the top wall of the second engaging groove 143. When the lower lever 170 is deployed, it pushes upward, and the first section 197 engages within the stopper groove 145. The stopper groove 145 restricts the rotation of the lower lever 170 when the water tank assembly 130 is pushed upward. This prevents the rotation of the lower lever 170 due to changes in the direction of the force applied during the upward push, which could affect the upward push of the water tank assembly 130.

[0112] Please refer to Figures 10 to 14When the pull-down rod 170 is in the retracted state, the first section 197 overlaps the bottom wall of the first engaging groove 141 located above the receiving groove 139. The bottom wall of the first engaging groove 141 bears the weight of the pull-down rod 170, and the pull-down rod 170 will not fall downward. When the user needs to extend the pull-down rod 170, the user first rotates the pull-down rod 170 along the axis of the second section 199 so that the first section 197 rotates out of the first engaging groove 141 and is located directly above the receiving groove 139, and then pulls the pull-down rod 170 downward. When the pull-down rod 170 is pulled to the lowest point and cannot be pulled further, the pull-down rod 170 is rotated again so that the first section 197 rotates into the second engaging groove 143. In this way, when the water tank assembly 130 is pushed upward by the pull-down rod 170 later, the pull-down rod 170 will not retract into the receiving groove 139. When the user does not use the pull-down rod 170 and needs to store the pull-down rod 170 upward, the user first rotates the pull-down rod 170 to rotate the first section 197 and rotate out a second snap-fit groove 143 to correspond to the receiving groove 139, then pushes the pull-down rod 170 upward until the height of the first section 197 is higher than the height of the bottom wall of the second snap-fit groove 143, and then rotates the pull-down rod 170 again to make the first section 197 inserted into the first snap-fit groove 141 to complete the storage.

[0113] Please refer to Figure 15 and Figure 16 In another optional embodiment, the mounting groove 133 is provided on the bottom wall of the water tank assembly 130, and the lower pull rod 170 is reversibly mounted in the mounting groove 133. The lower pull rod 170 in the storage state can be reversed downward to the use state, so that the lower pull rod 170 extends downward. The lower pull rod 170 in the use state can be reversed upward to the storage state, so that the lower pull rod 170 is accommodated in the mounting groove 133.

[0114] In this embodiment, the pull-down rod 170 is reversibly installed in the installation groove 133, so that the user can conveniently accommodate the pull-down rod 170 in the installation groove 133, and can also unfold the pull-down rod 170 downward when it is convenient to use.

[0115] Furthermore, the lower pull rod 170 is provided with a rotating portion 203 , and the side wall of the installation groove 133 is provided with an inserting hole 148 . The rotating portion 203 is installed in the inserting hole 148 , and the lower pull rod 170 can be flipped downward or upward along the axis of the rotating portion 203 .

[0116] Please refer to Figure 15 and Figure 16Furthermore, the pull-down rod 170 includes a gripping rod 205 and two connecting rods 207. The two connecting rods 207 are arranged opposite to each other, one end of the gripping rod 205 is connected to the end of one connecting rod 207, and the other end of the gripping rod 205 is connected to the end of the other connecting rod 207. The side walls of the two connecting rods 207 away from one end of the gripping rod 205 are both provided with a rotating part 203, and the two rotating parts 203 are coaxially arranged. The mounting groove 133 includes a first groove section, a second groove section and a third groove section. The first groove section and the second groove section are spaced apart. The third groove section is arranged between the first groove section and the second groove section, and its two ends are connected to the first groove section and the second groove section in a one-to-one correspondence. The side walls of the first groove section and the second groove section away from the third groove are both provided with plug-in holes 148. The two rotating parts 203 are plugged into the two plug-in holes in a one-to-one correspondence. When the lower link 170 is in the retracted position, the two connecting rods 207 are accommodated in the first and second groove sections, and the gripping rod 205 is accommodated in the third groove section. That is, the lower link 170 is U-shaped, and the mounting groove 133 is also a U-shaped groove. In this way, the gripping rod 205 between the two connecting rods can be used for gripping or as a clothes hanger.

[0117] Furthermore, the pull-down rod 170 also includes a support rod 209, and the two ends of the support rod 209 are connected to the ends of the two connecting rods 207 away from the gripping rod 205 in a one-to-one correspondence. That is, a rectangular frame-shaped pull-down rod 170 is formed. The mounting groove 133 also includes a fourth groove section, which is spaced apart from the third groove section, and the two ends of the fourth groove section are connected to the ends of the first groove section and the second groove section away from the third groove section in a one-to-one correspondence. The support rod 209 is installed in the fourth groove section, and the mounting groove 133 is a rectangular annular groove. This arrangement of the pull-down rod 170 can make the structure of the pull-down rod 170 more stable.

[0118] Please refer to Figures 4 to 7 In this embodiment, the water tank assembly 130 includes a water tank 149 and a water tank tray 151. The water tank tray 151 comprises a base plate and surrounding panels enclosing three sides of the base plate, with the remaining side being open. The water tank 149 is mounted within a water tank mounting cavity 311 formed by the base plate and the surrounding panels and can be removed from the open cavity. The lower pull rod 170 is mounted on the water tank tray 151, and the mounting slot 133 is also provided on the water tank tray 151.

[0119] Secondly, in other embodiments, the water tank assembly 130 may also be integrated, for example, integrally molded or assembled, and when water is needed, the user can directly add water into the water tank assembly 130 using a container.

[0120] In this embodiment, guide rail grooves are recessed inwardly on the outer sides of the enclosures on opposite sides of the water tank tray 151, extending along the height of the enclosures. The telescopic assembly 110 comprises two telescopic rails, each of which is screwed into the guide rail grooves at its bottom end.

[0121] In this embodiment, the telescopic rail comprises three sections. When extended, the three sections are connected in sequence. In the shortened state, the second and third sections can be accommodated within the first section. The extended length of the telescopic rail is approximately 60 cm. Of course, the extended length of the telescopic rail can be selected to be longer or shorter, depending on the needs, to ensure that the indoor unit 310 can be mounted on a wall. When the telescopic rail is fully extended, the user can conveniently add water to the water tank assembly 130 while standing on the ground.

[0122] In this embodiment, the bottom plate of the water tank tray 151 is tilted in the front-to-back direction and also in the left-to-right direction. Thus, after the user places the water tank 149 on the bottom plate of the water tank tray 151, the tilt of the bottom plate of the water tank tray 151 guides the water tank 149 in the front-to-back direction and the left-to-right direction, allowing the water tank 149 to move to a predetermined position on the water tank tray 151 and align the water tank 149 with the water pump 213 assembly.

[0123] In this embodiment, the mounting groove 133 is located below the telescopic assembly 110, and the positions correspond. That is, the mounting groove 133 is located directly below the guide rail groove, which saves more space and reduces the space occupied by the guide rail groove and the mounting groove 133, thereby increasing the volume of the water tank 149. For example, when there is one mounting groove 133, the mounting groove 133 is set on one side of the enclosure and is located directly below the guide rail groove. When there are two mounting grooves 133, the two mounting grooves 133 are set on the enclosures on both sides in a one-to-one correspondence, and the two guide rail grooves are located directly above the two mounting grooves 133. Of course, in some embodiments outside the present application, the mounting groove 133 and the guide rail groove can also be set at intervals on the enclosure, and staggered in the front-to-back direction and / or staggered in the left-to-right direction of the enclosure.

[0124] Please continue to refer to Figures 4 to 7Furthermore, the water tank device 100 also includes a mounting base 211 and a water pump 213. The mounting base 211 is fixedly mounted on the water tank mounting cavity 311, and the mounting base 211 is provided with a water pump frame 215 extending downward. The water pump 213 is installed at the bottom of the water pump frame 215, and the water pump 213 is connected to the humidification assembly 330 through a pipeline. The water tank 149 is provided with an upward opening 131. When the water tank 149 is in the water supply position, the water pump frame 215 is inserted into the interior of the water tank 149 through the opening 131 of the water tank 149. When the water tank 149 is in the water adding position, the water pump frame 215 is moved out of the water tank 149 through the opening 131 and is located above the water tank 149. That is, when the user pulls down the water tank tray 151 in the water supply position to move the water tank 149 downward to the water filling position, since the water pump bracket 215 is fixed relative to the indoor unit 310, the water pump bracket 215 and the water pump 213 will be separated from the water tank 149 through the opening 131 of the water tank 149 as the water tank 149 moves downward. After the user has finished filling the water tank 149 with water, in the process of pushing the water tank 149 upward, since the position of the water pump bracket 215 corresponds to the opening 131 of the water tank 149 in the vertical direction (i.e., the up and down direction), as the water tank 149 rises, the water pump bracket 215 will gradually be inserted into the water tank 149 through the opening 131. When the water tank 149 is lifted to the water supply position, the bottom of the water pump bracket 215 extends to the bottom of the water tank 149, thereby completing the connection between the water pump bracket 215 and the water tank assembly 130.

[0125] In this embodiment, the mounting base 211 and the water pump 213 are fixedly mounted in the water tank mounting cavity 311. This allows the water tank 149 and the water pump 213 to be easily separated when the water tank 149 is moved downward, and the water pump 213 to be easily installed in the water tank 149 when the water tank 149 is moved upward. The fixed mounting of the water pump 213 also prevents the wiring harness and pipes of the water pump 213 from being disconnected during the downward and upward movement of the water tank 149, and also avoids the need to separately disassemble and assemble the water pump 213 and pipes during the water filling process.

[0126] In this embodiment, the water pump bracket 215 of the mounting base 211 is installed within the water tank mounting cavity 311 via a mounting opening defined at the top of the cavity 311. That is, it is installed from top to bottom within the cavity 311. The mounting base 211 is fixedly connected to the top wall of the indoor unit 310 via bolts. The pipe connecting the water pump 213 and the humidification assembly 330 is secured through the inner wall of the indoor unit 310, connecting the two.

[0127] In this embodiment, the mounting base 211 includes a top plate 217 and side plates 219 arranged on both sides of the top plate 217. The water pump frame 215 is arranged in the center of the gap between the two side plates 219, and the two sides of the water pump frame 215 form gaps with the two side plates 219 respectively. When the water tank 149 is installed in the water supply position in the water tank installation cavity 311, the water pump frame 215 is inserted into the water tank 149, and the assembly plates on both sides are located on the left and right sides of the outside of the water tank 149. The top ends of the two telescopic guide rails are screwed to the two side plates 219 in a one-to-one correspondence. Of course, in some embodiments of the present application, the top ends of the two telescopic guide rails can also be connected to the side walls on the left and right sides of the water tank installation cavity 311 in a one-to-one correspondence through screws.

[0128] Generally, during assembly, the water pump 213 is first installed at the bottom of the water pump bracket 215. The top ends of the two telescopic rails are then mounted on the assembly plates on either side of the mounting base 211. The assembled unit is then installed within the water tank mounting cavity 311 through the mounting opening at the top of the water tank mounting cavity 311. The mounting base 211 is then fixedly connected to the top wall of the indoor unit 310, and the pipes and wiring harness are connected. Furthermore, the bottom ends of the two telescopic rails are then pulled downward out of the water tank mounting cavity 311 through the mounting notch 313 at the bottom of the water tank mounting cavity 311. The water tank tray 151 is then installed between the two telescopic rail assemblies, and the bottom ends of the telescopic rails are secured to the side panels 219 on either side of the water tank tray 151 with screws. This makes installation much more convenient.

[0129] Furthermore, a water tank cover 221 is provided on the water pump bracket 215. When the water tank 149 is installed in the water tank installation cavity 311 and in the water supply position, the water tank cover 221 covers the opening 131 of the water tank 149 to prevent dust and the like from falling into the water tank 149. Furthermore, because this embodiment is provided with telescopic guide rails, the water tank assembly 130 is relatively stable during the raising and lowering process, and the water in the water tank 149 generally does not spill.

[0130] Secondly, the water tank cover 221 can also be movably mounted on the water pump frame 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 frame 215 passes through the through hole of the water tank cover 221, and then a limiter is provided below the water pump frame 215 located below the water tank cover 221. This allows 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 limiter and stops. When the water tank assembly 130 moves upward, the water tank cover 221 and the top of the water tank assembly 130 abut against each other to seal the water tank 149. Afterwards, the water tank cover 221 will move upward under the push of the water tank assembly 130, thereby preventing water from spilling out of the water tank assembly 130 during the upward movement. Furthermore, the top of the water tank cover 221 can be set as a downward groove. When water comes out of the gap between the through hole and the water pump frame 215, the water will flow back into the water tank 149 body along the side wall of the groove to avoid water spilling on the outside.

[0131] Furthermore, the water pump 213 assembly also includes a water pump cover, which is mounted on the water pump frame 215 by means of snaps, and encloses the water pump 213 cavity with the water pump frame 215. A hole is provided at the bottom of the water pump 213 cavity. The water pump 213 is mounted at the bottom of the water pump 213 cavity. A liquid level sensor is also mounted on the water pump frame 215. The mounting seat 211 and the water pump frame 215 are integrally formed. During assembly, the water pump 213 is first mounted on the water pump frame 215, and then the water pump cover is snapped onto the water pump frame 215, and the liquid level sensor and the silver ion sterilization module are mounted at a preset position on the water pump frame 215. The assembled assembly is then mounted downwardly through the mounting port into the water tank mounting cavity 311.

[0132] In this embodiment, the water pump bracket 215 is set on the mounting base 211, and the opening 131 of the water tank 149 is upward. In this way, when the water tank tray 151 moves downward with the water tank 149, the water pump bracket 215 can be moved out of the water tank 149 as the water tank 149 moves downward, and there is no need to operate the water pump 213 when adding water. When the water tank tray 151 moves upward with the water tank 149, the water pump bracket 215 can be directly inserted into the water tank 149 through the opening 131, so that there is no need to operate the water pump 213 when removing and installing the water tank 149.

[0133] Please refer to Figures 17 to 20 In this embodiment, the water tank device 100 also includes a locking assembly 230, which is arranged in the water tank installation cavity 311. The locking assembly 230 is configured to fix the water tank 149 and the water tank tray 151 of the water tank assembly 130 at the water supply position in the water tank installation cavity 311. The locking assembly 230 can also be unlocked under the action of external force to release the water tank assembly 130.

[0134] In this embodiment, by providing a locking assembly 230 , the water tank tray 151 and the water tank 149 can be snap-fitted to ensure installation stability when they are accommodated in the installation notch 313 .

[0135] To add water to the water tank 149 during use, the user first unlocks the latch assembly 230 and then pulls the water tank tray 151 downward. The guide rail assembly extends the water tank tray 151, carrying the water tank 149 downward out of the mounting notch 313, to a position below the indoor unit 310. The user can then remove the water tank 149 and add water to it, or directly add water to the water tank 149 mounted on the water tank tray 151. After adding water, the user pushes the water tank tray 151 upward, causing the guide rail assembly to shorten, allowing the water tank tray 151 and the water tank 149 to be accommodated in the water supply position within the water tank mounting cavity 311 through the mounting notch 313. The guide rail assembly guides the water tank tray 151 during its raising and lowering, ensuring alignment with the mounting notch 313 and stable movement. Furthermore, after the water tank tray 151 is pulled downward, the retractable guide rails also provide an upward pull to the water tank tray 151, making it easier for the user to add water to the water tank 149.

[0136] Please refer to Figure 17 and Figure 18 In one embodiment, the locking assembly 230 includes a ball pressing rebounder 231, and the telescopic assembly 110 has multiple sections of retractable telescopic guide rails. The top section of the telescopic assembly 110 is connected to the mounting seat 211, and the bottom section of the guide rail is connected to the water tank tray 151. The ball and the rebound base of the ball pressing rebounder are 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 the guide rails are in the shortened position, the ball can be clamped on the rebound base. Pushing the water tank assembly 130 upward can release the rebound base from the spray ball.

[0137] This embodiment adopts a ball-pressing rebound device, which is simple and convenient to install. When in use, pushing the water tank tray 151 upward drives the lowermost guide rail of the telescopic assembly 110 to move upward, so that the ball is engaged or separated with the rebound base, making it easier to use.

[0138] It should be noted that the bumper press rebound device is also called the beetle self-locking device, which is a common hardware accessory. It can achieve the connection and unlocking between the bumper and the rebound base by pressing.

[0139] Of course, in some embodiments of the present application, one of the bumper and the rebound base of the bumper pressing and rebounding device can be installed on the mounting seat 211, and the other can be installed on the water tank tray 151.

[0140] Generally, there are two sets of ball-bumping press-return devices, one for each set of telescopic rails. This makes the connection more stable.

[0141] Please refer to Figure 19 and Figure 20 In another embodiment, the locking assembly 230 includes a rebounder 233, which is laterally mounted on a sidewall of the water tank mounting cavity 311. A locking hole 153 is provided on the sidewall of the water tank tray 151. When the telescopic assembly 110 is in the shortened state, the telescopic rod of the rebounder 233 can be inserted into the locking hole 153 (i.e., when the water tank tray 151 and the water tank 149 are accommodated in the water supply position of the water tank mounting cavity 311, the locking hole 153 and the rebounder 233 are aligned). A guide block 155 is provided on the lower periphery of the locking hole 153. The guide block 155 has an inclined guide slope 157. When the water tank tray 151 moves upward, the guide slope 157 pushes the telescopic rod of the rebounder 233 toward the interior of the rebounder 233, thereby extending the telescopic rod of the rebounder 233 and inserting it into the locking hole 153, or retracting it out of the locking hole 153.

[0142] The locking assembly 230 provided in this embodiment adopts a rebounder 233, and a locking hole 153 and a guide slope 157 are set on the water tank tray 151. The telescopic rod of the rebounder 233 can be extended or retracted by pushing the water tank tray 151 upward, thereby facilitating user operation and installation. It is only necessary to install the rebounder 233 at the corresponding position on the side wall of the water tank installation cavity 311.

[0143] In this embodiment, two rebounders 233 are installed, and the two rebounders are installed on the left and right side walls of the water tank installation cavity 311 respectively, extending horizontally outward.

[0144] It should be noted that the rebounder 233, also known as the rod-type rebounder 233 and the telescopic rod-type rebounder 233, is a device that uses a telescopic rod structure to achieve a rebound function, generally including: 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. Spring: built into the telescopic rod, used to provide the elastic force required for rebound or slow closing. The spring can be a coil spring, a torsion spring or a gas spring. 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, which is used to lock the telescopic rod when it is extended to a specific position to prevent accidental retraction. Trigger device: used to transmit external pressing or pulling force to trigger the telescopic action of the telescopic rod. The inner rod of the telescopic rod generally has an extended state and a retracted state, and can be maintained in these two positions. When the telescopic rod is subjected to axial thrust to compress the telescopic rod, the telescopic rod can be converted from an extended state to a shortened state and maintained. When the telescopic rod in the shortened state is subjected to an axial thrust, it can be extended to the telescopic state under the action of the spring.

[0145] It should also be noted that when the telescopic rod of the rebounder 233 is inserted into the keyhole 153, it also abuts the guide bevel 157. To add water to the water tank 149, the user pushes the water tank tray 151 upward. This movement causes the guide bevel 157 to also move upward, compressing the telescopic rod of the rebounder 233 and moving it out of the keyhole 153, where it remains in its shortened state. The user then pulls the water tank tray 151 downward to remove the water tank tray 151 and the water tank 149 from the mounting notch 313. After adding water, the user pushes the water tank tray 151 upward, causing the guide bevel 157 to further compress the telescopic end of the rebounder. The compressed telescopic rod, under the action of the spring, then extends and inserts into the keyhole 153, securing the water tank tray 151. The principle of the push-to-pull rebounder 233 is similar to that of a push-to-pull pen: a first press extends it, while a second press retracts it.

[0146] Please refer to Figures 1 to 3 as well as Figures 21 to 24 In this embodiment, the humidifying assembly 330 is a wet membrane assembly. The front side of the indoor unit 310 is provided with an assembly slot 317 that communicates with the air outlet duct 315, and the wet membrane assembly is mounted in the assembly slot 317. In this embodiment, the water tank assembly 130 is installed within the indoor unit 310 through the mounting notch 313, while the membrane assembly is mounted in the assembly slot 317 on the front side of the indoor unit 310 that communicates with the air outlet duct 315. This allows the water tank assembly 130 to supply water to the humidifying assembly 330 via a pipe, and the air delivered from the air outlet duct 315 by the crossflow fan of the air conditioner 300 passes through the humidifying assembly 330, removing moisture from the humidifying assembly 330. This allows the humidified air to be delivered over long distances, leveraging the air delivery capacity of the crossflow fan of the air conditioner 300, thereby increasing the humidification range. Furthermore, since the air conditioner 300 supplies hot air to the humidifying component 330 when the air conditioner 300 is in heating operation, there is no need to add a separate heating device and air supply component to the humidifying component 330, which saves space and cost.

[0147] In this embodiment, a panel air duct is formed between the middle frame of the indoor unit 310 and the panel 321. The panel 321 air duct is connected to the outlet air duct 315. When the cross-flow fan is running, the air can be sent to the outlet air duct 315, and then flow from the outlet air duct 315 to the panel air duct, and the humidified air is discharged through the humidification component 330.

[0148] Typically, the humidification function of air conditioner 300 is often used during winter heating. When the hot air delivered from the crossflow fan's outlet passes through humidification assembly 330, the water on humidification assembly 330 evaporates and mixes with the air, forming humidified air that is then delivered indoors by humidification assembly 330. Because the crossflow fan has a strong air delivery capacity, the hot air humidified by humidification assembly 330 can flow over a greater distance, thus humidifying a large area.

[0149] Please refer to Figures 1 to 3 as well as Figures 21 to 24 In this embodiment, the humidification assembly 330 includes a wet membrane 331, a wet membrane rack 333, and a mounting rack 335. The wet membrane 331 is mounted within the wet membrane rack 333. The mounting rack 335 is mounted within the assembly slot 317. An assembly cavity 337 is provided on the front side of the mounting rack 335. A water trough 339 and a water inlet connected to the water trough 339 are provided at the top of the mounting rack 335. The water trough 339 has multiple drain holes 341 along its length. A pipe is connected to the water inlet. The wet membrane rack 333 is mounted within the assembly cavity 337, and the drain holes 341 are located above the wet membrane rack 333. The water pump 213 pumps water into the water trough 339. After evenly flowing through the water trough 339, the water drops through the drain holes 341 onto the wet membrane 331 of the wet membrane rack 333, thereby humidifying the wet membrane 331.

[0150] In this embodiment, the humidifying assembly 330 is provided with a mounting bracket 335 to mount the wet film rack 333. This facilitates installation and removal of the wet film rack 333 when cleaning or replacing the wet film 331. A water tank 339 and a water inlet connected to the water tank 339 are provided at the top of the mounting bracket 335. A pipe connected to the water pump 213 supplies water to the water tank 339. The water in the water tank 339 then drips through the drip holes 341 onto the wet film 331 of the wet film rack 333, thereby humidifying the wet film 331.

[0151] Furthermore, the mounting bracket 335 is snap-fitted into the assembly slot 317 on the front side of the indoor unit 310. The wet film rack 333 is also snap-fitted into the assembly cavity 337 from the front side of the mounting bracket 335. When the wet film rack 333 is removed, it can be removed from the front side of the indoor unit 310.

[0152] Please refer to Figures 1 to 3 as well as Figures 21 to 24 In this embodiment, a water receiving groove 343 is provided on the lower side of the wet film rack 333, and a water outlet 345 is provided that communicates with the water receiving groove 343. The mounting frame 335 is provided with a water inlet groove 347 and a drain outlet 349 that communicates with the water inlet groove 347. The drain outlet 349 is provided with a drain connector. After the wet film rack 333 is mounted on the mounting frame 335, the water outlet 345 communicates with the water inlet groove 347. The drain connector is connected to a drain pipe. The drain pipe is connected to the water receiving pan of the indoor unit 310. In some embodiments, the drain pipe also directly leads to the outside of the indoor unit 310 to drain water outdoors.

[0153] Because excess humidification water may fall from the water drop hole 341 onto the wet membrane 331, a water receiving trough 343 is provided on the wet membrane frame 333 to collect excess water. A water inlet trough 347 and a drainage connector are provided on the middle frame, and the water receiving trough 343 is connected to the water inlet trough 347 through the water outlet hole 345. This allows water in the water in the water inlet trough 343 to flow into the water inlet trough 347 through the water outlet and then drain to the water receiving tray or outside the indoor unit 310 through a drain pipe connected to the drainage connector. The purpose of providing the water inlet trough 347 is to replace the wet membrane 331 by removing the wet membrane frame 333. However, with the current arrangement of the drainage connector on the mounting frame 335, it is not necessary to remove the external drainage pipe when removing the wet membrane frame 333, which is more convenient.

[0154] In some other embodiments of the present application, the humidification component 330 may also be other types of humidification modules such as an ultrasonic humidification module. The present application does not limit the humidification component 330 to a wet membrane component.

[0155] In this embodiment, the panel 321 is mounted on the front side of the indoor unit 310. A clearance notch 323 is provided on the panel 321 at a position corresponding to the mounting groove 317 to prevent the wet film frame 333 from leaking outward. This allows the wet film frame 333 to be removed without removing the panel 321.

[0156] Of course, in some embodiments of the present application, a plurality of air outlet microholes may be provided on the panel 321 at positions corresponding to the assembly slots 317 to achieve wind-free delivery of the humidified airflow.

[0157] Secondly, the present application would also like to explain that the present application does not limit the water tank device 100 provided in this embodiment to be used only for humidification. It can also be applied to other scenarios where the indoor unit 310 requires water. For example, the water tank device 100 can also be used to supply water to the filter cleaning device to achieve filter cleaning.

[0158] In summary, the air conditioner 300 provided in this embodiment provides a pull-down rod 170 on the water tank assembly 100 mounted on the indoor unit 310. The pull-down rod 170 allows the water tank assembly 130 to be conveniently pulled down for water addition or pushed back up to the water supply position. The user can complete all steps of the water tank 149 filling process while standing on the ground, making operation more convenient. Furthermore, the water tank 149 can be constructed in a smaller size and at a lower cost without the need for a motor or actuator.

[0159] Although the present invention is disclosed as above, it is not limited thereto. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope defined by the claims.
