[0002] Indoor humidity is closely related to human health and daily life. Medical studies show that indoor humidity can be controlled between 30% and 80% in winter, and between 30% and 60% in summer. When humidity is within the normal range, the body and mind are at their optimal state, allowing for optimal work or rest. However, with improved living standards, especially the widespread use of air conditioning, problems caused by decreased indoor humidity have become increasingly prominent. Decreased indoor humidity can lead to decreased metabolic function, slower pulse and respiration, subcutaneous vasoconstriction, excessive skin tension, and weakened respiratory resistance, making individuals more susceptible to respiratory diseases. To maintain suitable air humidity, a humidifying air conditioner has been proposed, which delivers water from a tank to a humidifier for heating and vaporization.

[0042] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0044] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0045] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0046] In related technologies, as people pay more and more attention to the quality of their daily environment, coupled with poor ventilation in enclosed environments and the fact that air conditioners remove moisture from the air during operation, making the indoor air dry, some air conditioner indoor units now have an additional humidification function. When setting the humidification function, the water tank of the humidifier 301 needs to be installed on the indoor unit. However, when the indoor unit is a wall-mounted air conditioner, it is very inconvenient to add water to the water tank because it needs to be installed on the ceiling. Therefore, related technologies have designed a lifting water tank to supply water to the humidifier 301, but there are water or air leaks when supplying water.

[0047] To solve the current technical problems, refer to Figures 1 to 7This invention proposes a water supply device, including a fixed structure 10, a lifting structure 30, and a water tank structure 50. The fixed structure 10 has a water inlet connector 15, and a water inlet pipe 17 is connected to the water inlet connector 15. The lifting structure 30 is connected to the fixed structure 10. The water tank structure 50 includes a water tank body 51 and a water outlet pipe 53 located on the water tank body 51. A sealing structure 70 is provided at the water outlet pipe 53. The lifting structure 30 is connected to the water tank body 51 and drives the water tank body 51 to move up or down to approach or move away from the fixed structure 10. When the water tank body 51 is connected to the fixed structure 10, the water outlet pipe 53 and the water inlet connector 15 are connected, and the sealing structure 70 seals the water outlet pipe 53 and the water inlet connector 15.

[0048] With this water supply device, when the water tank body 51 is connected to the fixed structure 10, the water outlet pipe 53 and the water inlet connector 15 are also connected, and the sealing structure 70 seals the connection between the water outlet pipe 53 and the water inlet connector 15, which can effectively prevent air or water leakage when the water pump 171 draws water, and helps to increase the sealing performance during the water supply process.

[0049] In one embodiment of this application, the fixing structure 10 can be configured as follows: The fixing structure 10 includes an upper shell 11 and a lower shell 13. One side of the lifting structure 30 is fixedly installed on the upper shell 11, and the water inlet connector 15 is installed inside the upper shell 11. The water tank structure 50 is installed on the lower shell 13. The side of the lifting structure 30 facing away from the upper shell 11 is fixedly connected to the lower shell 13, and drives the lower shell 13 to lift the water tank structure 50. The upper shell 11 and the lower shell 13 are separate, which facilitates installation and allows for easy lifting of the water tank body 51. The upper shell 11 and the lower shell 13 can be square, circular, or other shapes to match the shape of the water tank body 51, or different shapes, all within the scope of protection of this application. Furthermore, the upper shell 11 and the lower shell 13 can be made of plastic or soft rubber, which facilitates processing and assembly, reduces the overall weight of the materials, and thus reduces the processing cost of the entire product. Of course, other materials, such as aluminum alloy or other materials, can also be used, which are also within the scope of protection of this application.

[0050] Furthermore, an insertion section (not shown) is provided on the side of the upper shell 11 near the lower shell 13, which is used to insert into the lower shell 13. A driving component (not shown) is also provided inside the upper shell 11 to drive the lifting structure 30 to rise and fall. The driving component is installed on the side wall of the upper shell 11 by screws, and a threaded hole (not shown) is correspondingly provided on the side wall of the upper shell 11 to facilitate the installation and fixation of the driving component. One side of the lifting structure 30 is fixedly connected to the upper shell 11 by bolts, and the other side is fixedly connected to the lower shell 13 by bolts. A water tank body 51 is also provided inside the lower shell 13. The water tank body 51 and the lower shell 13 are separately arranged. The water tank body 51 is inserted into the lower shell 13, or the water tank body 51 can be integrally arranged with the lower shell 13, with an insertable part on the lower shell 13 that mates with the insertion section of the upper shell 11. The lifting structure 30 is controlled by the driving component to drive the lower shell 13 to rise and fall, thereby driving the water tank body 51 to rise and fall, making the connection more secure and the lifting process more stable. Setting the drive unit on the outer wall of the upper shell 11 can save installation space inside the upper shell 11, and the insertion section is used to insert into the lower shell 13 to make the installation and cooperation of the two more stable.

[0051] In one embodiment of this application, the lifting structure 30 can be configured as follows: the lifting structure 30 includes a connecting cloth 31 and a guide column 33. One side of the connecting cloth 31 is connected to the upper shell 11, and the other side is connected to the lower shell 13. The connecting cloth 31 provides tension when the water tank body 51 is raised or lowered. One end of the guide column 33 is connected to the inner wall of the upper shell 11, and the other end is connected to the inner wall of the lower shell 13. The guide column 33 controls the movement of the water tank body 51 in the vertical direction. By using the connecting cloth 31 to provide tension for the raising and lowering of the water tank body 51, the force on the water tank body 51 can be evenly distributed, making the water tank body 51 more stable during the raising and lowering process. At the same time, by setting the guide column 33 to provide guidance for the raising and lowering of the water tank, the position of the water tank body 51 is prevented from shifting during the raising and lowering process, which would cause the water outlet pipe 53 and the water inlet connector 15 to fail to connect.

[0052] Furthermore, the connecting fabric 31 provides tension when the water tank body 51 rises. In this embodiment, the connecting fabric 31 is waterproof Oxford cloth, but is not limited to waterproof Oxford cloth. The connecting fabric 31 is a columnar structure with three sides surrounding one side and the open side facing the wall. The guide post 33 is placed inside the connecting fabric 31 to improve the overall appearance. One side of the connecting fabric 31 is glued to the driving component, and the other side is glued to the inner wall of the lower shell 13. When the water tank body 51 rises, the connecting fabric 31 is wrapped around the driving component, driving the lower shell 13 to rise, while the guide post 33 retracts. When the water tank body 51 falls, the driving component rotates in the opposite direction, and under the action of the gravity of the water tank body 51, the connecting fabric 31 extends, while the guide post 33 extends, thus completing one lifting and lowering process. Since one end of the connecting fabric 31 is glued to the inner wall of the lower shell 13 and is evenly distributed along the edge of the lower shell 13, the force is evenly distributed when the lower shell 13 rises or falls, making the lifting and lowering process more stable.

[0053] Furthermore, one end of the guide post 33 is connected to the upper shell 11, and the other end is connected to the lower shell 13. The guide post 33 can be configured as a square column, and its plane can fit against the inner wall of the upper shell 11 or the lower shell 13, and be fixed by bolts. The guide post 33 connects the upper shell 11 and the lower shell 13. When the lower shell 13 rises, the guide post 33 retracts; when the lower shell 13 descends, the guide post 33 extends, guiding the rise and fall of the lower shell 13 and preventing the lower shell 13 from shifting its position during rise or fall, thus further improving the stability of the rise and fall. The guide post 33 includes multiple telescopic sections (not shown), which are connected sequentially. The guide post 33 is composed of multiple telescopic segments connected in sequence. The diameter of the telescopic segments gradually decreases along the contraction direction. There is an overfit or clearance fit between two adjacent telescopic segments. When the lower shell 13 rises to the position of the upper shell 11, the guide post 33 is compressed to its shortest length, which helps to save space. When the lower shell 13 descends, the guide post 33 extends out to provide support and guidance.

[0054] In one embodiment of the technical solution of this application, the water outlet pipe 53 is disposed inside the water tank body 51. The water outlet pipe 53 extends in the vertical direction and is disposed between the bottom of the water tank body 51 and the water outlet so as to draw out all the water in the water tank. The water outlet pipe 53 is a rigid plastic pipe or other rigid pipe material, which is easy to insert into the water inlet connector 15.

[0055] Optionally, the water inlet pipe 17 is bent and installed inside the upper shell 11, which makes full use of the space of the upper shell 11.

[0056] Optionally, the water tank body 51 is in the shape of a cuboid, and the bottom of the water tank body 51 is provided with an inclined part 511. The shape of the water tank body 51 is cuboid, which makes it easier for the water outlet pipe 53 to extend in the vertical direction between the bottom of the water tank body 51 and the water outlet, so as to draw out all the water in the water tank body 51. Alternatively, it can be other shapes similar to the shape of an air conditioner. The inclined part 511 at the bottom of the water tank body 51 can not only match the shape of the air conditioner indoor unit body 300, making the overall external pipe look more beautiful, but also fully draw out the water in the water tank body 51.

[0057] Optionally, a water inlet 513 is provided on the top of the water tank body 51. When the water tank body 51 is lowered, water can be added to the water tank body 51 through the water inlet 513.

[0058] Optionally, a liquid level sensor 515 is installed inside the water tank body 51. The liquid level sensor 515 can feed back the water level information in the water tank body 51 to a control terminal such as a remote control or mobile phone. After receiving the water replenishment information fed back by the liquid level sensor 515, the water tank body 51 can be lowered and water can be added through the water inlet 513.

[0059] In one embodiment of this application, the sealing structure 70 can be configured as follows: the sealing structure 70 includes an adapter 71 and a connector 73. The adapter 71 is embedded in the fixed structure 10, with one end connected to the outlet pipe 53 and the other end connected to the inlet connector 15. The connector 73 is connected to the end of the outlet pipe 53 near the adapter 71 and is inserted into the end of the adapter 71 away from the inlet connector 15. By embedding the adapter 71 in the fixed structure 10 and providing the connector 73 at one end of the outlet pipe 53 inside the water tank, the connector 73 can be inserted into the adapter 71 after the water tank rises, or the adapter 71 can be inserted into the connector 73. This facilitates water intake after the water tank body 51 rises and also seals the water supply pipeline, preventing water or air leakage during the water intake process.

[0060] The adapter 71 can be a circular tube, with its middle section snapped into the upper shell 11. A mounting plate is welded inside the upper shell 11 for mounting and fixing the adapter 71. The adapter 71 is inserted into the water tank body 51, and the other end of the adapter 71 is connected to a water inlet connector 15. The connector 73 can be inserted into the adapter 71, the water inlet connector 15 can be inserted into the adapter 71, or the adapter 71 can be inserted into the connector 73 and the adapter 71 into the water inlet connector 15, or other combinations are possible. It should be noted that the insertion here can be an interference fit, a transition fit, a clearance fit, or a threaded connection, etc., and is not limited here.

[0061] Furthermore, a sealing ring 731 is provided on the connector 73. One end of the connector 73 is inserted into the outlet pipe 53, and the sealing ring 731 is fitted onto the connector 73 and sandwiched between the connector 73 and the outlet pipe 53. Fitting the sealing ring 731 onto the connector 73 can further enhance the sealing between the connector 73 and the adapter 71, which helps to prevent water or air leakage in the water supply pipeline during water supply.

[0062] The diameter of the connector 73 can be smaller than the diameter of the outlet pipe 53. The connector 73 can be welded to one end of the inlet pipe 17 or connected to one end of the inlet pipe 17 by thread. The sealing ring 731 is fitted onto the connector 73. An installation groove for fitting the sealing ring 731 can be opened on the connector 73, which can not only increase the sealing between the sealing ring 731 and the connector 73, but also prevent the sealing ring 731 from falling off when the connector 73 is detached from the adapter 71.

[0063] Furthermore, a limit stop 711 is provided at the end of the adapter 71 near the water inlet connector 15. By providing the limit stop 711 at the end of the adapter 71 near the water inlet connector 15, the adapter 71 can be easily installed and fixed, preventing the adapter 71 from moving up and down inside the upper shell 11, which would result in a loose connection between the connector 73 and the adapter 71, causing water or air leakage during the water suction process.

[0064] Optionally, the inlet connector 15 is inserted into the adapter 71. This further improves the sealing performance of the adapter and facilitates installation. Of course, the adapter 71 can also be inserted into the inlet connector.

[0065] Optionally, the connector 73 is inserted into the adapter 71. This serves a similar function as described above, further improving the sealing performance of the adapter and facilitating installation. Alternatively, the connector 73 can be inserted into the adapter 71, or the adapter 71 can be inserted into the connector 73. This is also within the scope of this application.

[0066] It should be noted that when the connector 73 is inserted into the adapter 71, the diameter of the connector 73 is set to be smaller than the diameter of the outlet pipe 53, and the diameter of the adapter 71 is larger than the diameter of the connector 73. When the connector 73 is inserted into the adapter 71, the end face of the outlet pipe 53 and the connector 73 at the connection point fits snugly against the end face of the adapter 71 used for mating, making the connection between the connector 73 and the adapter 71 tighter. Similarly, when the adapter 71 is inserted into the connector 73, the diameter of the part of the adapter 71 used for mating is smaller than the diameter of the connector 73. The specific insertion method is the same as when the connector 73 is inserted into the adapter 71. The connection method between the inlet connector 15 and the adapter 71 is the same as the insertion method between the inlet connector 15 and the adapter 71, and will not be described again here. It should be noted that the insertion here can be an interference fit, an overfit, a clearance fit, or a threaded connection, etc., and is not limited here.

[0067] This invention also proposes an indoor air conditioning unit, which includes an indoor air conditioning unit body 300 and the aforementioned water supply device 100. The specific structure of the water supply device 100 is as described in the above embodiments. Since this indoor air conditioning unit adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here. The indoor air conditioning unit body 300 is equipped with a humidifier 301, and a water inlet pipe 17 connects to the humidifier 301. By setting the humidifier 301 inside the indoor air conditioning unit body 300, the water in the water tank body 51 is atomized, thereby increasing the indoor air humidity and improving the comfort of people's lives. The water inlet pipe 17 and the humidifier 301 are connected by the water inlet pipe 17.

[0068] The humidifier 301 can be fixedly connected to the panel of the indoor unit 300 of the air conditioner by screws. The humidifier 301 can be selected as a high-temperature steam module, which can atomize the water delivered to the high-temperature steam module, thereby increasing the indoor air humidity. The water inlet pipe 17 is connected to the humidifier 301 from the outside of the unit. There is no need to design the indoor unit 300 of the air conditioner separately, thereby reducing the design and manufacturing costs.

[0069] Further, refer to Figure 6 As shown, a water pump 171 is installed on the water inlet pipe 17. By installing the water pump 171 on the water inlet pipe 17, the water in the water tank body 51 can be transported to the humidifier 301 by the water pump 171. The water pump 171 is fixedly connected to the upper shell 11 by screws.

[0070] Optionally, the water inlet pipe 17 is inserted into the water inlet connector 15, and the water inlet pipe 17 and the water inlet connector 15 are connected by threads. Alternatively, the water inlet connector 15 can be sleeved inside the water inlet pipe 17, with an interference fit or an overfit between the water inlet connector 15 and the water inlet pipe 17. The water inlet pipe 17 is a rigid water pipe, which is convenient for distribution inside the upper shell 11 and also convenient for arrangement on the outside of the machine body, making the space utilization more efficient.

[0071] Optionally, a heat insulation cover 301a is provided on the outside of the humidifier 301. The heat insulation cover 301a is fixedly connected to the indoor unit body 300 of the air conditioner and completely covers the humidifier 301.

The heat insulation cover 301a is provided on the outside of the humidifier 301 and completely covers the humidifier 301. It is fixedly connected to the panel by screws.

[0072] The present invention also proposes an air conditioner, which includes an outdoor unit and an indoor unit as described above. The specific structure of the indoor unit is as described in the above embodiments. Since the present air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0073] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
