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 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 add water to a water tank installed in a wall-mounted indoor unit.

[0006] In order to solve the above problems, the utility model provides a water tank device and an air conditioner, which can conveniently add water to a water tank installed in an indoor unit.

DETAILED DESCRIPTION

[0069] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0070] 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.

[0071] 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, 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.

[0072] 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. 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 water tank assembly 100 is 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 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.

[0073] Please refer to Figures 1 to 5 In this embodiment, the water tank device 100 includes a water tank assembly 130 and a pull-down rod 170. The water tank assembly 130 is mounted within the water tank mounting cavity 311. The water tank assembly 130 is used to store water for humidification. The pull-down rod 170 is disposed on the water tank assembly 130 and extends downward, thereby pulling down or pushing up the water tank assembly 130.

[0074] Typically, the installation height of a wall-mounted indoor unit 310 is between 1.8 meters and 2.2 meters, or even higher. This invention 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 the water tank assembly 130 down using the pull-down rod 170. After adding water, the user can push the water tank assembly 130 up using the pull-down rod 170 and install it in the water tank installation cavity 311. Throughout the entire process of adding water to the water tank assembly 130, the user does not need to climb high. Furthermore, the water tank assembly 130 does not require a motor or actuator during both the raising and lowering processes, thereby saving space and cost. Overall, the water tank assembly 130 can be installed sufficiently large within the limited space of the water tank installation cavity 311, thereby increasing the capacity of the water tank assembly 130.

[0075] 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.

[0076] Please refer to Figure 6 Furthermore, the water tank assembly 130 is provided with a mounting groove 133, and the lower pull rod 170 is installed in the mounting groove 133. The lower pull rod 170 has a received state in which it is received in the mounting groove 133 and an extended state in which it extends out of the mounting groove 133. When the lower pull rod 170 is in the extended state, the lower pull rod 170 extends downward.

[0077] 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.

[0078] 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.

[0079] In this embodiment, the lower pull rod 170 is telescopically installed in the installation slot 133 . In the accommodated state, the lower pull rod 170 can be extended downward to an expanded state.

[0080] In this embodiment, the lower pull rod 170 is installed in the installation groove 133 in a telescopic manner, so that it can be easily stored and unfolded.

[0081] Please refer to Figures 6 to 9 In this embodiment, the telescopic rod 171 assembly includes the telescopic rod 171, a snap-fit assembly 173, and an unlocking assembly 175. The sidewalls of the mounting slot 133 are spaced apart in the height direction with a first snap-fit hole 135 and a second snap-fit hole 137, with the first snap-fit hole 135 located above the second snap-fit hole 137. The telescopic rod 171 is mounted within the mounting slot 133. The snap-fit assembly 173 is disposed at the top of the telescopic rod 171. When the telescopic rod 171 is in the retracted state, the snap-fit assembly 173 snaps into the first snap-fit hole 135. When the telescopic rod 171 is in the extended state, the snap-fit assembly 173 snaps into the second snap-fit hole 137. The unlocking assembly 175 is disposed at the bottom end of the telescopic rod 171 and extends to the snap-fit assembly 173. Pressing the unlocking assembly 175 drives the snap-fit assembly 173 to retract the telescopic rod 171. The lower pull rod 170 provided in this embodiment can be extended and retracted in the up and down directions, thereby making it more convenient to store and unfold.

[0082] 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.

[0083] Furthermore, the unlocking assembly 175 includes a button portion 187, a guide portion 189, and a second spring 191. The button portion 187 is provided 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 provided 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. The top end of the guide portion 189 is provided with a first guide surface 193. 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.

[0084] 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.

[0085] Please refer to Figures 6 to 9In 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 mounting slot 133 is provided in the water tank tray 151, and the lower pull rod 170 is mounted on the water tank tray 151.

[0086] 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.

[0087] In this embodiment, the water tank device 100 further includes a mounting base 211, a water pump 213, and a telescopic rail 110. The mounting base 211 is mounted in the water tank mounting cavity 311. The top end of the telescopic rail 110 is connected to the mounting base 211, and the bottom end of the telescopic rail 110 is connected to the water tank assembly 130. The mounting base 211 is provided with a downwardly extending mounting bracket for the water pump 213, and the water pump 213 is mounted on the mounting bracket 213. When the telescopic rail 110 is shortened, the water pump bracket 215 is inserted into the water tank mounting cavity 311 through the opening 131 of the water tank assembly 130, and the mounting bracket for the water pump 213 is inserted into the water tank assembly 130. When the telescopic rail 110 is extended, the water tank assembly 130 is moved out of the water tank mounting cavity 311 through the mounting notch 313, and the mounting bracket for the water pump 213 is positioned outside the water tank assembly 130.

[0088] In this embodiment, the telescopic guide rail 110 guides the water tank assembly 130 during its downward and upward movement, thereby ensuring stable vertical movement. The telescopic guide rail 110 also aligns the water tank assembly 130 with the mounting notch 313 in height, allowing the water pump bracket 215 to be inserted into the water tank 149.

[0089] Furthermore, 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 enclosure. Two telescopic rails 110 are provided, the bottom ends of which are screwed into the guide rail grooves, and the top ends of which are fixedly connected to the mounting base 211 via screws.

[0090] Please refer to Figures 6 to 9In this embodiment, the telescopic rail 110 comprises three sections. In the extended state, 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 110 is approximately 60 cm. Of course, the extended length of the telescopic rail 110 can be selected to be longer or shorter as needed to ensure that the indoor unit 310 can be mounted on a wall. When the telescopic rail 110 is fully extended, the user can conveniently add water to the water tank assembly 130 while standing on the ground.

[0091] In this embodiment, the water tank device 100 also includes a locking assembly (not shown in the figure), which is arranged in the water tank installation cavity 311. The locking assembly can fix the water tank tray 151 when the water tank assembly 130 is installed in the water supply position in the water tank installation cavity 311, and the locking assembly can also be unlocked under the action of external force to release the water tank assembly 130.

[0092] In this embodiment, a locking assembly is provided so that when the water tank tray 151 and the water tank 149 are accommodated in the installation notch 313 , they can be snap-fitted to ensure the stability of the installation.

[0093] Specifically, the locking assembly can be a locking structure such as a rebounder, a snap assembly, or an electromagnetic lock, as long as it can fix the water tank assembly 130 in the water tank installation cavity 311 and the user can unlock it by standing on the ground.

[0094] Please refer to Figures 1 to 3 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.

[0095] Of course, in some other embodiments of the present application, the humidification component 330 is also an ultrasonic humidification component or other types of humidification components.

[0096] 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.
