Description

Technical Field

[0001] The utility model relates to the field of air conditioning, and 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 air conditioner indoor units are typically installed at high altitudes, adding water to the humidification module requires climbing high, making it inconvenient. To avoid this need for height-based water addition, conventional techniques typically employ an electric drive mechanism to raise and lower the water tank. This allows the tank to be lowered during refilling and then extended afterward. These electric drive mechanisms employ either a motor-driven pulley to retract and release a pull cord, or a motor-driven, foldable, and retractable structure (e.g., a scissor frame) to raise and lower the water tank.

[0004] Regardless of which of the above two methods is used, a motor and an actuator are required to implement it, and the motor and the actuator will inevitably take up a large space, which will lead to the problems of increasing the size of the indoor unit, reducing the size of the water tank, and increasing costs. 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.

[0006] To solve the above problems, the present application provides a water tank device that can pull down and push up the water tank assembly through a pull-down rod, so that the water tank assembly can be raised and lowered more conveniently without the need for a motor, avoiding the problem of using a motor affecting the volume and cost of the indoor unit and water tank assembly.

[0007] In a first aspect, the utility model provides a water tank device, which is applied to an indoor unit of an air conditioner. The indoor unit is provided with a water tank installation cavity. The water tank device includes a water tank assembly, a telescopic assembly and a pull-down rod.

[0008] The water tank assembly is used to contain water;

[0009] The lower end of the telescopic assembly is connected to the water tank assembly, and the upper end of the telescopic assembly is configured to be disposed in the water tank mounting cavity;

[0010] When the telescopic assembly is in a shortened state, the water tank assembly can be accommodated in the water tank installation cavity;

[0011] When the telescopic assembly is in the extended state, the water tank assembly can be moved out of the water tank installation cavity;

[0012] The pull-down rod is arranged on the water tank assembly and extends downward. The water tank assembly can be pulled down or pushed upward by the pull-down rod. The axis of the pull-down rod is staggered with the axis of the telescopic assembly so that the pull-down rod is located on one side of the telescopic assembly.

[0013] Since the height of the indoor unit of the air conditioner in the vertical direction is approximately between 1.8 meters and 2.2 meters, the present application staggers the axis of the lower pull rod and the axis of the telescopic assembly so that the lower pull rod is located on one side of the telescopic assembly, that is, the lower pull rod and the telescopic assembly are staggered in the horizontal plane. This avoids the lower pull rod and the telescopic assembly from influencing each other in the height direction, thereby saving space in the height direction to select a longer telescopic assembly, so that the shortened length of the telescopic assembly is as close as possible to the height of the water tank installation cavity in the vertical direction. In this way, after the telescopic assembly is fully unfolded, the height from the ground is lower, making it easier for users to add water to the water tank.

[0014] In an optional embodiment, the water tank assembly is provided with a mounting groove, and the mounting groove is provided along the height direction of the water tank assembly;

[0015] The axis of the mounting slot is staggered with the axis of the telescopic assembly so that the mounting slot is located on one side of the telescopic assembly;

[0016] The pull-down rod is installed in the installation groove. The pull-down rod has a storage state in which the rod is accommodated in the installation groove and a use state in which the rod extends out of the installation groove. The pull-down rod extends downward in the use state.

[0017] The present application provides a mounting slot to better accommodate the pull-down rod. By offsetting the axis of the mounting slot with the axis of the telescopic assembly, the mounting slot can be deeper in the height direction of the water tank assembly, thereby accommodating a longer pull-down rod. When the pull-down rod is deployed, the length of the pull-down rod extending to the bottom side of the indoor unit is longer, allowing the user to easily pull the pull-down rod while standing on the ground.

[0018] In an optional embodiment, there are two telescopic assemblies, which are arranged on opposite sides of the water tank assembly in a one-to-one correspondence, and the axis of the installation groove and the axis of the two telescopic assemblies are staggered.

[0019] The present invention provides a telescopic assembly on each of the two opposite sides of the water tank assembly, thereby enabling the water tank assembly to move upward and downward stably. The mounting slot and the two telescopic assemblies are staggered, thereby saving height space and preventing the mounting slot and the two telescopic assemblies from interfering with each other in the height direction.

[0020] In an optional embodiment, the mounting groove and a telescopic assembly are arranged on the same side of the water tank assembly, and are spaced apart from each other.

[0021] This application sets the mounting groove and the telescopic assembly on the same side, so that the pull-down rod can make the water tank assembly more stable when pulling down and pushing up, so that the water tank assembly can move down or up smoothly and prevent the water in the water tank assembly from spilling out.

[0022] In an optional embodiment, the mounting slots are arranged on two adjacent sides of the water tank assembly in a one-to-one correspondence with one telescopic assembly. This arrangement facilitates assembly and saves space.

[0023] In an optional embodiment, the mounting slot includes a receiving slot, a first clamping slot, and a second clamping slot;

[0024] The receiving groove is arranged on one side of the water tank assembly along the height direction of the water tank assembly;

[0025] The first engaging groove is provided on the side wall of the receiving groove near the upper end and is communicated with the receiving groove;

[0026] The second engaging groove is provided on the side wall of the receiving groove near the lower end and is connected to the receiving groove;

[0027] The bottom wall of the receiving groove is provided with a protruding hole;

[0028] When the lower pull rod is in the extended state, the second section extends downward out of the extension hole, and the first section is engaged with the second engaging groove;

[0029] When the lower pull rod is in the retracted state, the second section is at least partially received in the receiving groove, and the first section is clamped in the first clamping groove.

[0030] The present application sets the mounting slot and the lower pull rod to the above-mentioned structure, which is simpler and more stable.

[0031] In an optional embodiment, the lower pull rod includes a telescopic pull rod, a clamping assembly, and an unlocking assembly, and the side wall of the mounting slot is provided with a first clamping hole and a second clamping hole spaced apart in the height direction, and the first clamping hole is located above the second clamping hole;

[0032] The telescopic pull rod is installed in the installation slot;

[0033] The clamping assembly is arranged at the top end of the telescopic pull rod;

[0034] When the telescopic pull rod is in the retracted state, the clamping assembly is clamped in the first clamping hole, and when the telescopic pull rod is in the extended state, the clamping assembly is clamped in the second clamping hole;

[0035] The unlocking assembly is arranged at the bottom end of the telescopic pull rod and extends to the clamping assembly. Pressing the unlocking assembly can drive the clamping assembly to retract the telescopic pull rod.

[0036] The present application sets the lower pull rod and the mounting groove to the above-mentioned structure, which makes it more convenient to use and the structure more stable.

[0037] In an optional embodiment, the telescopic rod is "U"-shaped, the water tank assembly is provided with two mounting grooves, the two ends of the top of the telescopic rod are installed in the two mounting grooves one by one, and the axes of the two mounting grooves are staggered with the axes of the two telescopic assemblies.

[0038] The present application sets the telescopic pull rod to be U-shaped, which has stronger stability, and when the telescopic pull rod is extended downward, the grip portion can also be used to hang clothes, etc. The axes of the two mounting slots and the axes of the two telescopic components are staggered, so that they can interfere with and affect each other.

[0039] In an optional embodiment, the two mounting slots and the two telescopic assemblies are disposed on opposite sides of the water tank assembly in a one-to-one correspondence;

[0040] The line connecting the projections of the two mounting grooves on the horizontal plane is parallel to the line connecting the projections of the two telescopic components on the horizontal plane; or, the line connecting the projections of the two mounting grooves on the horizontal plane intersects with the line connecting the projections of the two telescopic components on the horizontal plane.

[0041] The present application allows the line connecting the projections of the two mounting grooves on the horizontal plane to be parallel to or intersect with the line connecting the projections of the two telescopic components on the horizontal plane, thereby making the overall force of the water tank device more stable and easier to pull and push.

[0042] In an optional embodiment, the water tank assembly has two sides opposite to each other in a first direction and two sides opposite to each other in a second direction, the first direction and the second direction are two directions vertical within the horizontal direction, the two telescopic assemblies are arranged one-to-one on the two opposite sides of the water tank assembly in the first direction, and the two mounting grooves are arranged one-to-one on the two opposite sides of the water tank assembly in the second direction.

[0043] In the present application, the two mounting grooves are arranged on opposite sides of the water tank assembly in the first direction, and the two telescopic assemblies are arranged on both sides of the water tank assembly in the second direction, so that the force on the water tank assembly is more uniform.

[0044] In a second aspect, the present invention provides an air conditioner, comprising an indoor unit, a humidifying assembly, and a water tank device according to any one of the aforementioned embodiments;

[0045] A water tank installation cavity is provided in the indoor unit, and the water tank installation cavity has a downward disassembly opening;

[0046] The top end of the telescopic assembly is installed in the water tank installation cavity;

[0047] The water tank assembly is installed in the water tank installation cavity and can be pulled out downwards from the disassembly opening;

[0048] The humidifying component is arranged in the indoor unit, and the water in the water tank component can be used for humidifying the humidifying component.

[0049] The air conditioner provided in the present application can facilitate water adding operations for users because the water tank assembly can be moved between a water adding position and a water supply position via a lower pull rod. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0067] 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.

[0068] Please refer to Figures 1 to 3The 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 downwardly facing mounting notch 313. The water tank assembly 100 is mounted within the water tank mounting cavity 311. The humidifying assembly 330 is mounted within the indoor unit 310. The water tank assembly 130 and the humidifying assembly 330 are connected by a pipe, and the water tank assembly 130 can supply water to the humidifying assembly 330.

[0069] It should be noted that this indoor unit 310 is a wall-mounted unit and generally includes a base, a middle frame, a crossflow fan, an air guide plate, and a heat exchanger. The crossflow fan and heat exchanger are mounted on the base. The middle frame is mounted on the base, enclosing the crossflow fan and heat exchanger. The middle frame is provided with an air outlet connected to the air outlet duct. The air guide plate is mounted on the air outlet, and when the crossflow fan is running, air is supplied from the air outlet duct to the indoor room.

[0070] In this embodiment, the water tank installation cavity 311 is located 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. The water tank assembly 100 can be installed within the water tank installation cavity 311 through the mounting notch 313 and can be pulled downward through the mounting notch 313 to refill the water tank 141 of the water tank assembly 100. Of course, in other embodiments of the present application, the water tank installation cavity 311 can also be located on the right side of the indoor unit 310.

[0071] Please refer to Figures 1 to 6In this embodiment, the water tank device 100 includes a water tank assembly 130, a telescopic assembly 110, and a lower pull rod 150. 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 in the water tank mounting cavity 311 of the indoor unit 310 through a mounting notch 313. When the telescopic assembly 110 is shortened, the water tank assembly 130 is accommodated in 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 in 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 also 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. A pull-down rod 150 is disposed on the water tank assembly 130 and extends downward to pull the water tank assembly 130 downward or push it upward during the filling process. The axis of the pull-down rod 150 is offset from the axis of the telescopic assembly 110, so that the pull-down rod 150 is located on one side of the telescopic assembly 110. The axis of the pull-down rod 150 is offset from the axis of the telescopic assembly 110, so that the pull-down rod 150 is located on one side of the telescopic assembly 110.

[0072] Generally, the installation height of the indoor unit 310 of a wall-mounted air conditioner 300 is between 1.8 meters and 2.2 meters, or even higher. In this application, a downwardly extending pull-down rod 150 is provided 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 water tank assembly 130 through the pull-down rod 150 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 through the pull-down rod 150, so that the user does not need to climb up during the entire process of adding water. The water tank assembly 130 can be raised and lowered without the need for a motor or an actuator, thereby saving space and cost. In addition, the water tank assembly 130 can be set large enough in the limited space of the water tank installation cavity 311, thereby increasing the capacity of the water tank assembly 130. Secondly, since the height of the indoor unit 310 of the air conditioner 300 in the vertical direction is about 20 cm, in this embodiment, the axis of the lower pull rod 150 is staggered with the axis of the telescopic assembly 110 so that the lower pull rod 150 is located on one side of the telescopic assembly 110, that is, the lower pull rod 150 and the telescopic assembly 110 are staggered in the horizontal plane, so as to avoid the lower pull rod 150 and the telescopic assembly 110 from influencing each other in the height direction, thereby saving space in the height direction to select a longer telescopic assembly 110, so that the shortened length of the telescopic assembly 110 is as close as possible to the height of the water tank installation cavity 311 in the vertical direction, so that after the telescopic assembly 110 is fully unfolded, the height from the ground is lower, and it is more convenient for users to add water to the water tank 141.

[0073] It should be noted that the axis of the lower pull rod 150 and the axis of the telescopic assembly 110 can be staggered in the front-to-back direction, in the left-to-right direction, or in both the front-to-back direction and the left-to-right direction.

[0074] Please refer to Figure 4 、 Figure 5 、 Figure 6 and Figure 7 Furthermore, the water tank assembly 130 has four side walls in the left and right directions and the front and back directions. The side walls of the water tank assembly 130 are provided with mounting grooves 132, and the mounting grooves 132 are arranged along the height direction of the water tank assembly 130. The axis of the mounting groove 132 is staggered with the axis of the telescopic assembly 110 so that the mounting groove 132 is located on one side of the telescopic assembly 110. The pull-down rod 150 is installed in the mounting groove 132. The pull-down rod 150 has a storage state in which it is accommodated in the mounting groove 132 and an expanded state in which it extends out of the mounting groove 132. When the pull-down rod 150 is in the expanded state, the pull-down rod 150 extends downward.

[0075] 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 132 is provided on the side wall of the water tank assembly 130, so that the pull-down rod 150 can be stored in the mounting groove 132 during the season when the humidification function is not used, thereby making it more beautiful and convenient to transport. In winter or before using the humidification function, the pull-down rod 150 is moved out of the mounting groove 132. If the humidification function is used for a period of time thereafter, the pull-down rod 150 does not need to be stored in the mounting groove 132. Before the humidification function is not used for a long time, the pull-down rod 150 can be stored in the mounting groove 132, or it can be installed in the indoor unit 310 so that the pull-down rod 150 is always in the expanded state.

[0076] Secondly, in this embodiment, the axis of the mounting groove 132 is offset from the axis of the telescopic assembly 110. This allows the mounting groove 132 to be deeper in the height direction of the water tank assembly 130, thereby accommodating a longer pull-down rod 150. When the pull-down rod 150 is deployed, the pull-down rod 150 extends a longer distance to the underside of the indoor unit 310, allowing the user to easily pull the pull-down rod 150 while standing on the ground.

[0077] If the axis of the installation slot 132 coincides with the axis of the telescopic assembly 110, the length of the telescopic assembly 110 and the length of the lower pull rod 150 both need to be shortened to ensure that the lower pull rod 150 is accommodated in the installation slot 132 in the retracted state. For example, the height of the water tank assembly 130 is 20 cm. When they coincide, the installation slot 132 occupies a portion of the space in the height direction, while the telescopic guide rail occupies a portion of the space in the height direction. The length of the two together is 20 cm. For example, the lower pull rod 150 needs to be shortened to 10 cm, and the telescopic guide rail also needs to be shortened to 10 cm. In this case, the length of the lower pull rod 150 will be shorter, and the length of the lower pull rod 150 extending downward in the extended state will be shorter. It will be difficult for the user standing on the ground to grab the lower pull rod 150 to pull down the water tank assembly 130. It will also cause the water tank assembly 130 to be pulled down to the water filling position. When the telescopic assembly 110 is fully extended, the water tank assembly 130 is at a high height from the ground, so that the user cannot conveniently add water to the water tank 141. Please refer to Figure 4 、 Figure 5 、 Figure 6 and Figure 7In this embodiment, the mounting groove 132 and the telescopic assembly 110 are offset so that they do not affect each other in the height direction. When the height of the water tank assembly 130 is 20 cm, the maximum length of the pull-down rod 150 and the telescopic assembly 110 in the shortened state can be selected to be 20 cm. In this way, after the water tank assembly 130 is installed in the water tank mounting cavity 311, the pull-down rod 150 will extend downward by about 20 cm in the extended state, allowing the user to easily grab the pull-down rod 150 while standing on the ground. The maximum length of the telescopic assembly 110 can also be selected to be 20 cm. For example, a 20 cm long three-section telescopic guide rail can reach about 60 cm when fully extended. This allows the water tank assembly 130 to be at a suitable height after being pulled down, allowing the user to conveniently add water to the water tank assembly 130 while standing on the ground.

[0078] It should be noted that the staggered arrangement of the axis of the mounting groove 132 and the axis of the telescopic assembly 110 can mean that the mounting groove 132 and the telescopic assembly 110 are located on the same sidewall of the water tank assembly 130 and are staggered, for example, in the width direction of the sidewall or in the thickness direction of the sidewall. Alternatively, the mounting groove 132 and the telescopic assembly 110 can be located on different sidewalls of the water tank assembly 130. For example, the telescopic assembly 110 can be located on the left and right sidewalls of the water tank assembly 130, while the mounting groove 132 is located on the rear sidewall.

[0079] Please refer to Figure 4 、 Figure 5 、 Figure 6 and Figure 7 In this embodiment, there are two telescopic assemblies 110, which are disposed one-to-one on opposite sides of the water tank assembly 130. The opposite sides of the water tank assembly 130 can be the front-to-back sides or the left-to-right sides. The axis of the mounting slot 132 is offset from the axis of the two telescopic assemblies 110.

[0080] In this embodiment, two telescopic assemblies 110 are disposed on opposite sides of the water tank assembly 130, thereby enabling stable upward and downward movement of the water tank assembly 130. Furthermore, the mounting slot 132 and the two telescopic assemblies 110 are staggered, thereby saving height space and preventing the mounting slot 132 and the two telescopic assemblies 110 from interfering with each other in the height direction.

[0081] Please refer to Figure 6 and Figure 7 In one embodiment, the mounting groove 132 and a telescopic assembly 110 are disposed on the same side of the water tank assembly 130 and are spaced apart from each other.

[0082] In this embodiment, the mounting groove 132 is arranged on the same side of the telescopic assembly 110, so that the pull-down rod 150 can make the water tank assembly 130 more stable when pulling down and pushing up, thereby allowing the water tank assembly 130 to move down or up smoothly and prevent the water in the water tank assembly 130 from spilling out.

[0083] It should be noted that the installation slot 132 and a telescopic assembly 110 are arranged on the same side of the water tank assembly 130 and the spacing between the two can be understood as the installation slot 132 and the telescopic assembly 110 are arranged on any side wall of the front, rear, left and right sides of the water tank assembly 130. The spacing can be set in the width direction of the side wall or in the thickness direction of the water tank assembly 130. Please continue to refer to Figure 6 For example, a telescopic assembly 110 is provided on the left side wall of a water tank assembly 130, and a mounting groove 132 is also provided on the left side wall of the water tank assembly 130. However, the mounting groove 132 and the telescopic assembly 110 are spaced apart in the front-to-back direction (i.e., the width direction of the side wall). For another example, a telescopic assembly 110 is provided on the left side wall of a water tank assembly 130, and a mounting groove 132 is also provided on the left side wall of the water tank assembly. The two are aligned in the front-to-back direction, but are offset in the left-to-right direction (i.e., the thickness direction of the left side wall).

[0084] Please continue to refer to Figure 4 、 Figure 5 、 Figure 6 and Figure 7 In this embodiment, the lower pull rod 150 includes a telescopic pull rod 151, a snap assembly 152, and an unlocking assembly 153. The mounting groove 132 is arranged along the height direction of the water tank assembly 130. The mounting groove 132 and one of the telescopic assemblies 110 are arranged on the same side of the water tank assembly 130, and the mounting groove 132 and the telescopic assembly 110 are spaced apart in the width direction of the side wall. The side wall of the mounting groove 132 is provided with a first clamping hole 133 and a second clamping hole 134 at intervals in the height direction, and the first clamping hole is located above the second clamping hole. The telescopic rod 151 is installed in the mounting groove 132, and the clamping assembly 152 is provided at the top end of the telescopic rod 151. When the telescopic rod 151 is in the stored state, the clamping assembly 152 is clamped in the first clamping hole 133. When the telescopic rod 151 is in the unfolded state, the clamping assembly 152 is clamped in the second clamping hole 134. The unlocking assembly 153 is provided at the bottom end of the telescopic rod 151 and extends to the clamping assembly 152. Pressing the unlocking assembly 153 can drive the clamping assembly 152 to retract the telescopic rod 151.

[0085] The telescopic lower pull rod 150 provided in this embodiment is more convenient to operate. In this embodiment, the mounting groove 132 and the telescopic assembly 110 are staggered in the width direction of the side wall of the water tank assembly 130, so that the side wall of the water tank assembly 130 can be set thinner, thereby increasing the volume of the water tank 141.

[0086] Please refer to Figure 6 For example, the mounting groove 132 is provided on the left side wall of the water tank 141, and one of the telescopic assemblies 110 is also provided on the left side wall of the water tank 141, but the mounting groove 132 and the telescopic assembly 110 are staggered in the front-to-back direction of the water tank assembly 130. In this way, the left side wall of the water tank assembly 130 can be provided thinner, thereby increasing the volume of the water tank assembly 130.

[0087] Please refer to Figure 7 、 Figure 8 and Figure 9 Furthermore, the unlocking assembly includes a guide post 154, a locking block 155, and a first spring 156. A hollow chamber 157 is provided within the telescopic rod 151, and a side hole 158 is provided on the side wall near the top of the telescopic rod 151, which communicates with the hollow chamber 157. The guide post 154 is mounted within the hollow chamber 157. The locking block 155 is mounted on the guide post 154, and the engaging post provided on the locking block 155 corresponds to the side hole 158. The first spring 156 is sleeved on the guide post 154 and abuts against the locking block 155. The first spring 156 provides a restoring force on the locking block 155, causing it to move away from the guide post 154, allowing the engaging post to extend out of the side hole 158 and engage with the first engaging hole 133 or the second engaging hole 134. The unlocking assembly 153 includes a button portion 159, a guide portion 161, and a second spring 162. The button portion 159 is provided at the bottom end of the extended pull rod. The second spring 162 abuts against the button portion 159 for resetting the button. The guide portion 161 is provided in the hollow chamber 157, and the bottom end of the guide portion 161 is connected to the button portion 159. The top end of the guide portion 161 extends to the locking block 155. The top end of the guide portion 161 is provided with a first guide surface 163, and the locking block 155 is provided with a second guide surface 164, and the first guide surface 163 abuts against the second guide surface 164. The first guide surface 163 and the second guide surface 164 are both inclined surfaces, which can convert the vertical movement of the guide portion 161 into the horizontal movement of the locking block 155. Pressing the button can compress the second spring 162, and can drive the guide portion 161 to move, thereby driving the locking block 155 to move toward the direction close to the guide column 154.

[0088] Please continue to refer to Figure 7 、 Figure 8 and Figure 9Furthermore, the telescopic rod 151 is U-shaped, and the telescopic rod 151 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 132. The first telescopic rod and the second telescopic rod are installed in the two mounting grooves 132 in a one-to-one correspondence. The button portion is installed in the gripping portion. There are two unlocking assemblies, and the two unlocking assemblies are respectively installed on the inner side of the top end of the first telescopic rod and the second telescopic rod. The guide portion 161 extends along the inside of the first telescopic rod and the second telescopic rod to the unlocking assembly. The axes of the two mounting grooves 132 are staggered with the axes of the two telescopic assemblies 110.

[0089] The telescopic rod 151 provided in this embodiment is a U-shaped telescopic rod 151 with greater stability, and when the telescopic rod 151 is extended downward, the grip portion can also be used to hang clothes, etc. The axes of the two mounting slots 132 and the axes of the two telescopic assemblies 110 are staggered, so that they can interfere with and affect each other.

[0090] Please refer to Figure 6 Furthermore, the two mounting grooves 132 and the two telescopic assemblies 110 are arranged on opposite sides of the water tank assembly 130 in a one-to-one correspondence. The connecting line of the two mounting grooves 132 projected on the horizontal plane is parallel to the connecting line of the two telescopic assemblies 110 projected on the horizontal plane.

[0091] In this embodiment, the connecting line of the two mounting grooves 132 projected on the horizontal plane is parallel to the connecting line of the two telescopic components 110 projected on the horizontal plane, so that the overall force of the water tank device 100 is more stable and easier to pull and push.

[0092] Please continue to refer to Figure 6 In this embodiment, the two opposite sides of the water tank assembly 130 can be the left and right sides. When the two mounting grooves 132 and the two telescopic assemblies 110 are disposed on the left and right walls of the water tank assembly 130 in a one-to-one correspondence, the two mounting grooves 132 can be located on the rear sides of the two telescopic assemblies 110. Of course, they can also be located on the front sides of the two telescopic assemblies 110, making the connecting lines parallel to each other.

[0093] In other embodiments, the two opposite sides of the water tank assembly 130 can also be the front side and the rear side. When the two mounting grooves 132 and the two telescopic assemblies 110 are arranged on the front side wall and the rear side wall of the water tank assembly 130 in a one-to-one correspondence, the two mounting grooves 132 can be located on the left side of the two telescopic assemblies 110 at the same time, or on the right side of the two telescopic assemblies 110 at the same time, so that the two connecting lines are parallel to each other.

[0094] Please refer to Figure 10 and Figure 11Of course, in some embodiments, the two mounting grooves 132 and the two telescopic components 110 are arranged on opposite sides of the water tank component 130 in a one-to-one correspondence, and the line connecting the two mounting grooves 132 projected on the horizontal plane intersects with the line connecting the two telescopic components 110 projected on the horizontal plane.

[0095] Please refer to Figure 10 For example, in one embodiment, the two opposing sides of the water tank assembly 130 may be the left and right sides. When the two mounting slots 132 and the two telescopic assemblies 110 are disposed on the left and right sides of the water tank assembly 130 in a one-to-one correspondence, one of the two mounting slots 132 is located in front of the telescopic assembly 110 disposed on the same side wall, while the other mounting slot 132 is located in the rear of the telescopic assembly 110 disposed on the same side wall. The angle between the two connecting lines can be determined according to the specific location, for example, 45° or 90°.

[0096] Please refer to Figure 11 For example, in another embodiment, the two opposing sides of the water tank assembly 130 may be the front and rear sides. When the two mounting slots 132 and the two telescopic assemblies 110 are disposed on the front and rear sidewalls of the water tank assembly 130 in a one-to-one correspondence, one of the two mounting slots 132 is located on the left side of the telescopic assembly 110 disposed on the same sidewall, while the other mounting slot 132 is located on the right side of the telescopic assembly 110 disposed on the same sidewall. The angle between the two connecting lines can be determined based on the specific location, for example, 45° or 90°.

[0097] In any of the above embodiments, the two groups of telescopic components 110 can be correspondingly arranged in the middle of the side wall of the water tank component 130 and symmetrically distributed, so that the forces on the two groups of telescopic components 110 can be more balanced.

[0098] Please refer to Figure 12 In some embodiments, the water tank assembly 130 has two opposing sides in a first direction and two opposing sides in a second direction, where the first direction and the second direction are two horizontal and vertical directions. The first direction may be a front-to-back direction, while the second direction is a left-to-right direction. The two telescopic assemblies 110 are disposed one-to-one on opposing sides of the water tank assembly 130 in the first direction, and the two mounting slots 132 are disposed one-to-one on opposing sides of the water tank assembly 130 in the second direction.

[0099] For example, the two mounting grooves 132 are arranged on both sides of the water tank assembly 130 in a one-to-one correspondence in the front-to-back direction, and the two telescopic assemblies 110 are arranged on both sides of the water tank assembly 130 in a left-to-right direction. Alternatively, the two mounting grooves 132 are arranged on both sides of the water tank assembly 130 in a one-to-one correspondence in the left-to-right direction, and the two telescopic assemblies 110 are arranged on both sides of the water tank assembly 130 in a front-to-back direction.

[0100] Preferably, the two mounting slots 132 are positioned in a one-to-one correspondence in the middle of the front-to-back sides of the water tank assembly 130, while the two telescopic assemblies 110 are positioned in the middle of the left-to-right sides of the water tank assembly 130. The line connecting the two telescopic assemblies 110 and the line connecting the two mounting slots 132 intersect in a cross shape. This cross-shaped arrangement provides more stable force on the water tank assembly 130.

[0101] Please refer to Figure 13 and Figure 14 In an optional embodiment, the mounting slots 132 are disposed on two adjacent sides of the water tank assembly 130, corresponding one-to-one with one telescopic assembly 110. The water tank assembly 130 has two opposing sides in a first direction and two opposing sides in a second direction. The first direction and the second direction are two horizontal and vertical directions. The two telescopic assemblies 110 are disposed on opposing sides of the water tank assembly 130 in the first direction, corresponding one-to-one. There is one mounting slot 132, which is disposed on one of the two opposing sides of the water tank assembly 130 in the second direction. One of the first and second directions is a front-to-back direction, and the other is a left-to-right direction.

[0102] For example, the two telescopic assemblies 110 are disposed on the left and right sides of the water tank assembly 130 in a one-to-one correspondence, and the mounting groove 132 is disposed on the rear side or the front side of the water tank assembly 130. Alternatively, the two telescopic assemblies 110 are disposed on the front and rear sides of the water tank assembly 130 in a one-to-one correspondence, and the mounting groove 132 is disposed on the left side or the right side of the water tank assembly 130.

[0103] Please refer to Figure 13 and Figure 14Specifically, the mounting slot 132 is located on the rear side of the water tank assembly 130, and the two telescopic assemblies 110 are arranged one-to-one on the left and right sides of the water tank assembly 130. The mounting slot 132 includes a receiving slot 135, a first engaging slot 136, and a second engaging slot 137. The first engaging slot 136 is located at the upper end of the receiving slot 135 and is located on one side of the receiving slot 135 in the width direction. The side of the first engaging slot 136 closest to the receiving slot 135 is connected to the receiving slot 135. The second engaging slot 137 is located at the lower end of the receiving slot 135 and is located on one side of the receiving slot 135 in the width direction. The side of the second engaging slot 137 closest to the receiving slot 135 is connected to the receiving slot 135. The bottom wall of the second engaging slot 137 is provided with an extension hole 139. The extension hole 139 is located in the middle of the width direction of the rear side wall of the water tank assembly 130. The lower pull rod includes a first section and a second section connected at an angle. The lower pull rod is mounted in the receiving slot. When the lower link 150 is in the extended state, the second section 166 extends downward from the extension hole 139, and the first section 165 is engaged with the second engaging groove 137. When the lower link 150 is in the retracted state, the second section 166 is at least partially received in the receiving groove 135, and the first section 165 is engaged with the first engaging groove 136.

[0104] In this embodiment, the receiving slot 135 is configured as described above. To deploy the lower rod 150, the user first rotates the lower rod 150 using the extended end of the second section 166, causing the first section 165 to rotate and move out of the first engaging slot 136. The user then pulls the lower rod 150 downward. When the lower rod 150 stops moving (due to the first section 165 abutting the bottom wall of the receiving slot 135), the second section 166 is fully extended. The lower rod 150 is then rotated again, bringing the first section 165 with it into the second engaging slot 137, completing the deployment process. To deploy the lower rod 150, the user can perform the corresponding operation. Since the first section 165 is engaged in the second engaging slot 137 when the lower rod 150 is extended, further upward force applied to the lower rod 150 prevents the lower rod 150 from retracting into the receiving slot 135. Such arrangement of the pull-down rod 150 can satisfy both the need to pull the water tank assembly 130 downward and to push the water tank assembly 130 upward.

[0105] It should be noted that the first clamping groove 136 and the second clamping groove 137 arranged on both sides of the receiving groove 135 in the height direction have side walls arranged on the receiving groove 135, and the whole forms a "concave" shaped groove that is flipped 90°.

[0106] Please refer to Figure 13 and Figure 14In this embodiment, the first section 165 and the second section are vertically connected. The first section 165 is formed by bending the top end of the second section 166. Secondly, the lower rod 150 also includes a gripping section 167 connected to the end of the second section 166 away from the first section 165. The length of the second section 166 is the same as the height of the receiving slot 135. When the lower rod 150 moves up along the receiving slot 135 until the gripping section 167 abuts the bottom wall of the water tank assembly 130, the first section 165 and the first engaging slot 136 are aligned in the height direction. Rotating the lower rod 150 can drive the engaging portion to insert into the first engaging slot 136. When the lower rod 150 is in the retracted state, the second section 166 is contained within the receiving slot 135, with only the gripping section 167 exposed. The user can operate the gripping section 167 to operate the lower rod 150 to extend it downward.

[0107] Furthermore, the gripping section 167 is formed by bending the lower end portion of the lower pull rod 150. The gripping section 167 extends in the same direction as or in the opposite direction to the first section 165. By making the gripping section 167 extend in the same direction as or in the opposite direction to the first section 165, the user can determine the orientation of the first section 165 by the orientation of the gripping section 167, thereby confirming whether the first section 165 is inserted into the first and second engaging slots 136 and 137.

[0108] Please refer to Figure 13 and Figure 14 Furthermore, a stopper groove 138 protrudes upward from the top wall of the second engaging groove 137. When the lower link 150 is deployed, the lower link 150 is pushed upward, and the first section 165 can be engaged with the stopper groove 138. The stopper groove 138 restricts the rotation of the lower link 150 when the water tank assembly 130 is pushed upward. This prevents the rotation of the lower link 150 due to changes in the force direction during the upward push process, which could affect the upward push of the water tank assembly 130.

[0109] When the lower rod 150 is in the retracted state, the first section 165 overlaps the bottom wall of the first engaging groove 136. The bottom wall of the first engaging groove 136 bears the weight of the lower rod 150, preventing the lower rod 150 from falling. When the user needs to extend the lower rod 150, the user first rotates the lower rod 150 along the axis of the second section 166 to move the first section 165 out of the first engaging groove 136. The first section 165 is located directly above the receiving groove 135, and then the lower rod 150 is pulled downward. When the lower rod 150 reaches its lowest point and cannot be pulled further, the user rotates the lower rod 150 again to rotate the first section 165 into the second engaging groove 137. In this way, when the water tank assembly 130 is later pushed upward by the lower rod 150, the first section 165 is engaged with the second engaging groove 137 and does not move upward. When the user does not use the pull-down rod 150 and needs to store the pull-down rod 150 upward, the user first rotates the pull-down rod 150 so that the first section 165 rotates out of the second engaging groove 137, and then pushes the pull-down rod 150 upward until the height of the first section 165 is higher than the height corresponding to the first engaging groove 136, and then rotates the pull-down rod 150 again so that the first section 165 is inserted into the first engaging groove 136.

[0110] In this embodiment, when the pull-down rod 150 is the aforementioned rotating pull-down type, only one mounting slot 132 is provided. For example, two telescopic assemblies 110 are arranged on the left and right sides of the water tank assembly 130, and the mounting slot 132 is located on the front or rear side of the water tank assembly 130. This ensures more stable force when the pull-down rod 150 is pulled downward. Of course, the two telescopic assemblies 110 can also be arranged on the front and rear sides of the water tank assembly 130, with the mounting slot 132 located on the left or right side of the water tank assembly 130, thereby staggering the telescopic assemblies 110 in the height direction.

[0111] Please refer to Figure 15 In another optional embodiment, there are two mounting slots 132. The lower pull rod 150 is U-shaped, with its ends correspondingly mounted in the two mounting slots 132. The telescopic assembly 110 has one mounting slot, and the two mounting slots 132 and the telescopic assembly 110 are located on the same side of the water tank assembly 130. The axes of the three mounting slots 132 are staggered.

[0112] Specifically, two mounting grooves 132 are provided on the rear side wall of the water tank assembly 130 , and the telescopic assembly 110 is provided between the two mounting grooves 132 and connected to the water tank assembly 130 .

[0113] Please refer to Figure 4 and Figure 5In this embodiment, the water tank assembly 130 includes a water tank 141 and a water tank tray 143. The water tank tray 143 includes a bottom plate 144 and side plates 145. The side plates 145 are disposed around the periphery of the bottom plate 144. The water tank 141 is mounted within a water tank mounting cavity 311 formed by the bottom plate 144 and the side plates 145. The telescopic assembly 110 and the mounting slot 132 are both disposed on the side plates 145.

[0114] Furthermore, in order to facilitate the disassembly of the water tank 141, side panels 145 are provided on three sides of the bottom plate 144, and one side is opened. When the user adds water to the water tank 141, the water tank 141 can be removed through the opened opening.

[0115] Please refer to Figure 6 and Figure 7 The water tank tray 143 has guide rail slots 146 recessed inwardly on the outer sides of the side panels 145 on opposite sides. These slots extend along the height of the side panels 145 and are offset from the axis of the mounting slot 132. The telescopic assembly 110 comprises two telescopic rails, each of which is screwed into the guide rail slots 146 at its lower end.

[0116] 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.

[0117] Please refer to Figures 4 to 7Furthermore, the water tank device 100 includes a mounting base 171 and a water pump 172. The mounting base 171 is fixedly mounted on the water tank mounting cavity 311 and is connected to the top wall of the water tank mounting cavity 311. The mounting base 171 is provided with a water pump frame 173 extending downward, and the water pump 172 is installed at the bottom of the water pump frame 173. The water pump 172 is connected to the humidification assembly 330 through a pipe. The water tank 141 is provided with an upward opening 131. When the water tank 141 is in the water supply position, the water pump frame 173 is inserted into the interior of the water tank 141 through the opening 131 of the water tank 141. When the water tank 141 is in the water adding position, the water pump frame 173 is moved out of the water tank 141 through the opening 131 and is located above the water tank 141. That is, when the user pulls down the water tank tray 143 in the water supply position to move the water tank 141 downward to the water filling position, the water pump bracket 173 is fixed relative to the indoor unit 310. As the water tank 141 moves downward, the water pump bracket 173 and the water pump 172 are separated from the water tank 141 through the opening 131 of the water tank 141. After the user finishes filling the water tank 141 with water, as the water tank 141 is pushed upward, the position of the water pump bracket 173 corresponds vertically (i.e., in the up-down direction) to the opening 131 of the water tank 141. As the water tank 141 rises, the water pump bracket 173 gradually inserts into the water tank 141 through the opening 131. When the water tank 141 is raised to the water supply position, the bottom of the water pump bracket 173 extends to the bottom of the water tank 141, thus completing the connection between the water pump bracket 173 and the water tank 141.

[0118] In this embodiment, the mounting base 171 and the water pump 172 are fixedly mounted in the water tank mounting cavity 311. This allows the water tank 141 and the water pump 172 to be easily separated when the water tank 141 is moved downward, and the water pump 172 to be easily installed in the water tank 141 when the water tank 141 is moved upward. The fixed mounting of the water pump 172 also prevents the wiring harness and pipes of the water pump 172 from being disconnected during the downward and upward movement of the water tank 141, and also avoids the need to separately disassemble and assemble the water pump 172 and pipes during water addition.

[0119] Please refer to Figures 4 to 7 In this embodiment, the mounting base 171 includes a top plate 174 and assembly plates 175 arranged on both sides of the top plate 174. The water pump frame 173 is arranged in the center of the gap between the two assembly plates 175, and gaps are formed between the two sides of the water pump frame 173 and the two assembly plates 175 respectively. When the water tank 141 is installed in the water supply position in the water tank installation cavity 311, the water pump frame 173 is inserted into the water tank 141, and the assembly plates 175 on both sides are located on the left and right sides of the outer side of the water tank 141. The top ends of the two telescopic guide rails are screwed to the two assembly plates 175 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. This facilitates the overall assembly.

[0120] In this embodiment, the air conditioner 300 further includes a locking assembly (not shown), which is disposed within the water tank mounting cavity 311. The locking assembly is configured to secure the water tank 141 and the water tank tray 143 of the water tank assembly 130 to the water supply position within the water tank mounting cavity 311. The locking assembly can also be unlocked by an external force to release the water tank assembly 130. The locking assembly can be a rebounder, a snap, or other structure, as long as it can secure and release the water tank assembly 130.

[0121] Please refer to Figures 1 to 3 In this embodiment, the humidification assembly 330 is a wet membrane assembly. A mounting slot 317, connected to the outlet duct, is located on the front of the indoor unit 310. The wet membrane assembly is mounted in this slot, and a water pump 172 supplies water to the wet membranes of the wet membrane assembly. Air from the outlet duct, supplied by the crossflow fan, passes through the wet membrane assembly, removes moisture from the membranes, and is then delivered to the indoor room, thereby humidifying the indoor environment.

[0122] Of course, 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.

[0123] Secondly, it should be noted that the present application does not limit the water tank device 100 provided in this example to be used only in the humidification function of the indoor unit 310. 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 clean the filter.

[0124] In summary, the air conditioner 300 provided in this embodiment provides a pull-down rod 150 on the water tank device 100 mounted on the indoor unit 310. The pull-down rod 150 allows the water tank assembly 130 to be conveniently pulled down for water filling or pushed back up to the water supply position. The user can complete all steps of the water filling process while standing on the ground, making operation more convenient. The telescopic assembly 110 mounted on the water tank assembly 130 and the pull-down rod 150 are offset in their axes, thereby saving space in the height direction and allowing the selection of a longer telescopic assembly 110.

[0125] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. Therefore, the scope of protection of the present utility model should be based on the scope of protection of the claims.
