Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to a water tank and an air conditioning device. Background Technology

[0002] Air conditioning devices are used to regulate air quality, such as adjusting parameters like humidity, temperature, and air quality. Existing water tanks used in air conditioning devices have an inlet port through which water flows directly into the tank. To increase the tank's capacity, the inlet port is typically positioned a certain distance from the bottom of the tank. When the tank is empty or the water level is low, water flowing into the tank through the inlet port will impact the bottom of the tank from a height due to gravity, or impact the surface of the water inside, generating noise.

[0003] To address the aforementioned issues, a buffer component, such as an absorbent sponge, is typically installed below the water inlet to absorb the impact of the water flow and suppress noise generation.

[0004] However, adding cushioning components such as absorbent sponges will increase assembly steps and time, thus increasing costs. Furthermore, prolonged immersion in water or remaining damp may lead to bacterial growth and unpleasant odors, affecting user experience. Additionally, water may leak from the inlet when the tank is tilted. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides a water tank and an air conditioning device. The water tank is equipped with a flow guide section, which includes a flow guide wall and a flow guide component. The flow guide wall extends towards the bottom surface of the tank to shorten the distance between it and the bottom surface or liquid surface of the tank. The flow guide component is located downstream of the water inlet to receive and disperse the liquid entering through the water inlet, reduce the liquid flow rate, and reduce or prevent liquid overflow from the water tank when the tank is tilted by cooperating with the water inlet.

[0006] The water tank provided by this utility model includes an inlet located at the top of the tank body for liquid to enter. The water tank further includes a flow guide for guiding the liquid entering from the inlet to the bottom of the water tank. The flow guide includes a flow guide wall extending protruding from the edge of the inlet towards the bottom surface of the tank body; and a flow guide member located downstream of the inlet and on the inner circumferential side of the flow guide wall, with a gap between the flow guide member and at least a portion of the flow guide wall.

[0007] According to an embodiment of the present invention, the flow guide wall includes: a first flow guide wall extending protruding from the edge of the water inlet toward the bottom surface of the tank; and a second flow guide wall extending protruding from the first flow guide wall toward the bottom surface of the tank; wherein a portion of the flow guide is located inside the first flow guide wall, and another portion of the flow guide is located inside the second flow guide wall.

[0008] According to an embodiment of the present invention, the second guide wall includes: a guide surface, which is the inner circumferential surface of the second guide wall; and a guide rib, which protrudes from the guide surface onto the inner circumferential side of the second guide wall. One end of the guide rib away from the guide surface contacts the guide member to support the guide member, thereby creating a gap between the guide surface and the guide member.

[0009] According to an embodiment of the present invention, the maximum inner diameter of the second guide wall is less than or equal to the diameter of the guide member.

[0010] According to an embodiment of the present invention, the guide member can move between the water inlet and the second guide wall; when the guide member moves to a first position close to the water inlet, the water inlet is closed, and when the guide member moves to a second position close to the second guide wall, the water inlet is opened.

[0011] According to an embodiment of the present invention, the maximum diameter of the water inlet is less than or equal to the diameter of the guide member.

[0012] According to an embodiment of the present invention, the first guide wall includes an inclined surface; the inclined surface is inclined from the side near the water inlet to the side near the bottom surface of the tank towards the inner circumference of the first guide wall.

[0013] According to an embodiment of the present invention, the water tank further includes a sealing element; the sealing element is disposed on the upstream side of the flow guide, and the water inlet is disposed on the sealing element.

[0014] According to an embodiment of the present invention, the sealing element includes: a first sealing element having the water inlet; and a second sealing element extending protruding from the first sealing element toward the guide element, the second sealing element including a connecting port communicating with the water inlet and located at the end of the second sealing element away from the water inlet.

[0015] According to an embodiment of the present invention, the diameter of the connecting port is greater than or equal to the diameter of the inlet, and the diameter of the connecting port is greater than or equal to the minimum diameter of the guide member.

[0016] According to an embodiment of the present invention, the second sealing member includes an inclined sealing wall extending from a side near the water inlet toward a side of the flow guide and inclined toward the outer periphery of the water inlet; the inclined sealing wall surrounds the water inlet and forms the communication port.

[0017] According to an embodiment of the present invention, at least a portion of the second seal is made of an elastic material.

[0018] The air conditioning device provided by this utility model includes: a water tank; a drain outlet for filling the water tank with water; a humidification unit for humidifying the air; and a water collection tray disposed below the humidification unit, wherein the water inlet of the water tank is disposed below the drain outlet.

[0019] As can be seen from the above technical solution, the water tank and air conditioning device with the water tank of this utility model have at least the following beneficial effects: Liquid entering the tank through the inlet is guided by the guide section, and the guide wall extends from the inlet to the bottom surface of the tank. Compared with the distance between the inlet and the bottom surface of the tank, the distance between the lower end of the guide wall and the bottom surface of the tank is shorter. Therefore, the impact of the liquid on the bottom surface or liquid surface of the water tank in the direction of gravity can be reduced, thereby suppressing noise. The guide component is located downstream of the inlet and on the inner circumference of the guide wall, suitable for receiving liquid and dispersing it before it drips onto the guide wall, and reducing the liquid flow velocity so that it passes through the gap between the guide component and the guide surface, further reducing the impact of the liquid on the liquid surface. In addition, through the cooperation of the guide component and the inlet, the overflow of liquid in the water tank can be reduced or prevented when the water tank is tilted.

[0036] For ease of explanation, water will be used as the storage liquid in the following embodiments.

[0037] The water tank of this utility model will be described in detail below with reference to the schematic diagram.

[0038] First Embodiment

[0039] Figure 1 A partial cross-sectional view according to an embodiment of the present invention is shown schematically. Figure 2 yes Figure 1 A partial enlarged view of part A of the illustrative embodiment shown.

[0040] This embodiment discloses a water tank, referring to 1 and... Figure 2 As shown, it includes a housing 1, a water inlet 23, and a flow guide 3.

[0041] The housing 1 forms the outline of the water tank for containing liquid, and includes a bottom surface 12 that is below the direction of gravity in normal use, a top surface 11 that is above the direction of gravity opposite to the bottom surface 12, and a side surface 13 connecting the top surface 11 and the bottom surface 12. In this embodiment, the housing 1 is approximately hollow cuboid in shape, and the side surface 13 includes a first side surface, a second side surface opposite to the first side surface, a third side surface, and a fourth side surface opposite to the third side surface. In other embodiments, the housing 1 may be approximately hollow cylindrical or other shapes.

[0042] The inlet 23 is located at the top of the water tank, specifically on the top surface 11, for allowing liquid to enter the tank. In this embodiment, the top surface 11 of the water tank also includes an opening and a tank cover covering the opening, the tank cover being detachably mounted on the tank body 1. The inlet 23 is located on the tank cover. In other embodiments, the inlet 23 may also be located on the top surface 11 other than the tank cover. In this embodiment, the side surface 13 of the water tank forms the opening. Optionally, in other embodiments, the top surface 11 of the water tank may be integrally connected to the side surface 13.

[0043] Furthermore, in this embodiment, the minimum inner diameter of the inlet 23 is greater than the inner diameter that generates surface tension in the water under the pressure caused by the minimum flow rate of the incoming water. That is, when the minimum flow rate of the incoming water is constant, the pressure it generates is constant, and the diameter that generates surface tension in the water is R1, while the minimum inner diameter of the inlet 23 is R2. R2 is greater than R1.

[0044] In this embodiment, the water inlet 23 is in the shape of a round hole. In other embodiments, the water inlet 23 may be in other shapes.

[0045] The water tank also includes a flow guide 3, through which liquid entering the water tank from the inlet 23 flows to the bottom of the water tank under the guidance of the flow guide 3.

[0046] The flow guide 3 includes a flow guide wall 31 and a flow guide element 32.

[0047] A flow guide wall 31 is disposed inside the water tank, protruding from at least a portion of the edge of the inlet 23 toward the bottom surface 12 of the tank body 1, for guiding the liquid to flow to the bottom of the water tank. "Protruding from the edge of the inlet 23" includes, but is not limited to, the edge position and vicinity of the inlet 23; that is, the flow guide wall 31 may be positioned at a certain distance from the edge of the inlet 23. "Protruding from at least a portion of the edge of the inlet 23" may also include the flow guide wall 31 protruding from a portion of the edge of the inlet 23, forming a non-enclosing sheet shape; or, the flow guide wall 31 protruding from the entire edge of the inlet 23, forming an enclosing cylindrical shape. The flow guide wall 31 includes a top end connected to the top surface 11 of the water tank, an end end located on the opposite side of the top end, and a surface connecting the top end and the end end.

[0048] In this embodiment, there is a certain distance H between the end of the guide wall 31 and the bottom surface 12 of the tank 1, and the distance H is less than or equal to the lowest water level WL of the tank. That is, 0 < H ≤ WL. The distance between the end of the guide wall 31 and the bottom surface 12 of the tank 1 refers to the vertical distance between the end of the guide wall 31 and the bottom surface 12 of the tank 1. In this embodiment, the water tank also includes a lowest water level sensor disposed inside the tank 1 for detecting the lowest water level. The distance H between the end of the guide wall 31 and the bottom surface 12 of the tank 1 is less than or equal to the water level height WL sensed by the lowest water level sensor. In other embodiments, the lowest water level WL can be determined in other forms, such as water level line markings.

[0049] In this embodiment, the guide wall 31 is provided on the top surface 11 of the water tank. Specifically, the guide wall 31 protrudes from the side of the water tank cover where the water inlet 23 is provided, and is in the shape of a cylinder that extends from the circumferential edge of the water inlet 23 toward the bottom surface 12 of the tank body 1.

[0050] The guide member 32 is located downstream of the inlet 23 and on the inner circumferential side of the guide wall 31. "Located on the inner circumferential side of the guide wall 31" means located on the inner circumferential side of the inlet 23. A gap 4 exists between the guide member 32 and at least a portion of the guide wall 31, meaning a gap 4 exists between at least a portion of the surface of the guide member 32 and the inner circumferential surface of the guide wall 31. In this embodiment, the guide member 32 is approximately spherical.

[0051] The specific implementation of the first embodiment will be described below.

[0052] In this embodiment, when water flows to the inlet 23 and into the tank 1 through the inlet 23, part of the water will flow into the tank 1 along the edge of the inlet 23, and another part of the water will directly enter the tank 1 from the center of the inlet 23.

[0053] Because the minimum inner diameter of the inlet 23 is larger than the inner diameter required to generate surface tension when water flows into the inlet 23 at the minimum flow rate, the water will not form a water film at the inlet 23 due to surface tension, even when water enters at the minimum flow rate.

[0054] When liquid enters the tank 1 through inlet 23, it flows downward along the edge of inlet 23. Since the edge of inlet 23 extends into the bottom surface 12 of tank 1 with a guide wall 31, under the guidance of the guide wall 31, some liquid flows along the inner circumferential surface of the guide wall 31 toward the bottom surface 12 of tank 1.

[0055] At this time, due to the large diameter of the inlet 23, when the liquid flow rate per unit time is large, a vortex may be generated due to the siphon phenomenon, resulting in noise.

[0056] Since a guide member 32 is provided on the downstream side of the inlet 23, and there is a gap 4 between the guide member 32 and the guide, when some liquid flows downward along the guide wall 31, it will flow downward along the gap 4 between the guide member 32 and the guide wall 31, thereby reducing the flow rate.

[0057] Meanwhile, when another part of the liquid enters the inlet 23 directly, it will first come into contact with the top of the guide member 32, and then be diverted to all sides under the guidance of the guide member 32. It will also flow downward through the gap 4 between the guide member 32 and the guide wall 31, thereby suppressing the generation of vortices.

[0058] As the liquid passes through the guide member 32, it continues to flow towards the bottom surface 12 of the housing 1 under the guidance of the guide wall 31. Since the distance between the end of the guide wall 31 and the bottom surface 12 of the housing 1 is relatively short, when the liquid drips from the end of the guide wall 31 onto the bottom surface 12 of the housing 1, it can further suppress the noise generated when the liquid drips from a higher distance onto the bottom surface 12 of the housing 1.

[0059] Furthermore, in this embodiment, the guide wall 31 is set at a certain distance from the bottom surface 12 of the housing 1, which can prevent interference between the guide wall 31 and the bottom surface 12 of the housing 1 due to manufacturing tolerances, thereby preventing the guide wall 31 from breaking.

[0060] Meanwhile, the distance H between the guide wall 31 and the bottom surface 12 of the tank 1 is less than or equal to the minimum water level WL of the water tank. When the water in the tank reaches the minimum water level, the distance between the end of the guide wall 31 and the liquid surface at the minimum water level is small, or it is in contact with or even submerged below the liquid surface. At this time, as the water flows downward along the surface of the guide wall 31 until it detaches from the end of the guide wall 31 and drips downward, because the distance between the end of the guide wall 31 and the liquid surface at the minimum water level is small, or it is in contact with the liquid surface, the water will drip directly onto the liquid surface and flow below the liquid surface, thereby suppressing the sound of the water flow impacting the liquid surface or the bottom surface 12 of the water tank.

[0061] Second Embodiment

[0062] The second embodiment of this utility model will be described below, wherein the same structure as the first embodiment will not be repeated.

[0063] Figure 3 yes Figure 1 A partial cross-sectional view of the guide section of the schematic embodiment shown. Figure 4 yes Figure 3 A partial cross-sectional view of the guide section shown from another perspective.

[0064] In this embodiment, refer to 3 and Figure 4 As shown, the flow guide wall 31 includes a first flow guide wall 311 and a second flow guide wall 312.

[0065] The first guide wall 311 is a sheet-like structure that extends from at least a portion of the edge of the inlet 23 toward the bottom surface 12 of the tank 1. It includes a first top end connected to the top surface 11 of the tank, a first end end located on the opposite side of the first top end and close to the bottom surface 12 of the tank, and a first surface connecting the first top end and the first end end. The first surface faces the inner circumferential side of the inlet 23.

[0066] The second guide wall 312 extends protruding from the first guide wall 311 toward the bottom surface 12 of the tank 1, and includes a second top end connected to the first end end, a second end end located on the opposite side of the second top end and close to the bottom surface 12 of the tank, and a second surface connecting the second top end and the second end end. The second surface includes a guide surface 33 formed by the inner circumferential surface of the second guide wall 312 facing the inner circumferential side of the inlet 23.

[0067] A portion of the flow guide 32 (such as the upper part of the flow guide 32) is located inside the area surrounded by the first flow guide wall 311, while another portion of the flow guide 32 (such as the lower part of the flow guide 32) is located inside the area surrounded by the second flow guide portion 3. That is, the flow guide 32 is located at the connection between the first end and the second end, including but not limited to the connection between the first end and the second end and its vicinity.

[0068] In this embodiment, the inlet 23 is circular, and the guide wall 31 is an enclosing cylindrical shape extending downward from the edge of the inlet 23. Correspondingly, the first guide wall 311 is an enclosing cylindrical shape extending downward from the edge of the inlet 23, and the second guide wall 312 is an enclosing cylindrical shape extending downward from the first guide wall 311. In other embodiments, the inlet 23 may also be of other shapes, and the first guide wall 311 or the second guide wall 312 may also be a non-enclosing sheet.

[0069] In this embodiment, the maximum diameter of the second guide wall 312 is less than or equal to the minimum diameter of the guide member 32. In this embodiment, the maximum diameter of the second guide wall 312 refers to the maximum diameter of its second top end. The maximum diameter refers to the maximum diameter distance between the guide surfaces 33 of the second guide wall 312.

[0070] Furthermore, in this embodiment, the distance between the first end of the first guide wall 311 and the plane where the inlet 23 is located is less than or equal to the distance between the second top end and the second end of the second guide wall 312.

[0071] Furthermore, in this embodiment, the guide member 32 is movable between the inlet 23 and the second guide wall 312.

[0072] When the guide member 32 moves to the first position near the inlet 23, the inlet 23 is closed. When the guide member 32 moves to the second position near the second guide wall 312, the inlet 23 is opened.

[0073] In this embodiment, the maximum diameter of the inlet 23 is less than or equal to the diameter of the guide member 32.

[0074] In this embodiment, the first position command guide 32 is positioned to contact the edge of the inlet 23, and on the projection perpendicular to the plane where the inlet 23 is located, the guide 32 completely covers the inlet 23, thereby closing the inlet 23.

[0075] The second position directs the flow guide 32 to not contact the inlet 23. In this embodiment, the second position directs the flow guide 32 to contact a portion of the flow guide surface 33 of the second flow guide wall 312, thus opening the inlet 23. That is, in this embodiment, the flow guide 32 directly cooperates with the inlet 23. When the flow guide 32 is in the first position, the inlet 23 is closed by the flow guide 32, and when the flow guide 32 is in the second position, a gap 4 is formed between the flow guide 32 and the inlet 23, allowing the inlet 23 to open.

[0076] In other embodiments, the guide member 32 can move between the inlet 23 and the second guide wall 312 via other transmission structures, thereby opening and closing the inlet 23. That is, in this embodiment, the guide member 32 and the inlet 23 may not be in direct contact, but rather indirectly cooperate through transmission structures and other enclosing structures. When the guide member 32 is in the first position, the transmission structure transmits the displacement change of the guide member 32 to the enclosing structure, causing the enclosing structure to close the inlet 23. When the guide member 32 is in the second position, a gap 4 is formed between the enclosing structure and the inlet 23, allowing the inlet 23 to open.

[0077] The specific implementation methods in this embodiment will be described below.

[0078] Since the guide wall 31 includes a first guide wall 311 and a second guide wall 312, the maximum diameter of the second guide wall 312 is less than or equal to the minimum diameter of the guide member 32. Therefore, the guide wall 31 can engage at the maximum diameter of the second guide wall 312. In this embodiment, the guide wall 31 and the second guide wall 312 engage at the second top end, thereby being fixed between the first guide wall 311 and the second guide wall 312.

[0079] Furthermore, the distance between the first end of the first guide wall 311 and the plane where the inlet 23 is located is less than or equal to the distance between the second top end and the second end of the second guide wall 312. Therefore, the guide member 32 is fixed closer to the inlet 23, which can further suppress the noise generated when the water flows from the inlet 23 into the guide member 32.

[0080] In addition, when the water tank is tilted due to external force, the plane where the inlet 23 is located changes from the upper position in the direction of gravity to the side 13 or the lower position, etc. The water in the tank may flow out of the inlet 23 through the guide wall 31. If the water in the tank 1 flows into the user's house or into other equipment equipped with this water tank, it may cause damage to the user's home furnishings or equipment.

[0081] In this embodiment, the guide member 32 can move between the inlet 23 and the second guide wall 312. When the water tank is tilted, the guide member 32 moves towards the inlet 23 under the action of gravity. When the guide member 32 moves to the first position, it will contact the edge of the inlet 23. Since the maximum diameter of the inlet 23 is less than or equal to the diameter of the guide member 32, when the guide member 32 contacts the edge of the inlet 23, it completely covers the inlet 23 on the projection perpendicular to the plane where the inlet 23 is located, thereby reducing the risk of water in the tank 1 flowing out of the inlet 23 or even gushing out in large quantities.

[0082] When the water tank returns to its normal state from the tilted state, the guide member 32 moves back to the second position under the action of gravity, that is, it comes into contact with the second guide wall 312, and is thus fixed between the first guide wall 311 and the second guide wall 312.

[0083] Therefore, while suppressing the noise generated by the water flow impacting the bottom surface 12 of the tank 1, it can further prevent water from flowing out of the tank when it is tilted.

[0084] Third Embodiment

[0085] The third embodiment of this utility model will be described below, wherein the same structure as the first and second embodiments will not be repeated.

[0086] In this embodiment, we continue to refer to... Figure 3 and Figure 4 As shown, the second guide wall 312 also includes guide ribs 34.

[0087] The guide rib 34 is a rib protruding from the guide surface 33 of the second guide wall 312 toward the inner circumference of the second guide wall 312. The end of the guide rib 34 away from the guide surface 33 contacts the guide member 32 to support the guide member 32, creating a gap 4 between the guide surface 33 and the guide member 32. In this embodiment, the maximum diameter of the second guide wall 312 refers to the maximum diameter between the opposing guide ribs 34. The end of the guide rib 34 near the inlet 23 contacts the guide member 32, meaning that in normal use, i.e., when the inlet 23 is above the direction of gravity, the guide member 32, under the action of gravity, contacts the guide rib 34 and, supported by the guide rib 34, is fixed between the first guide wall 311 and the second guide wall 312.

[0088] Furthermore, in this embodiment, on the end of the guide rib 34 near the inlet 23, there is an inclined surface 3111 that slopes from the inlet 23 side toward the bottom surface 12 of the housing 1 and toward the inner circumference of the first guide wall 311. The inclined surface 3111 contacts the guide member 32.

[0089] There is a gap 4 between the flow guiding surface 33 and the flow guiding member 32, that is, the distance between at least a portion of the opposing surfaces of the flow guiding surface 33 is greater than the diameter of the flow guiding member 32. This ensures that a certain distance is maintained between the surface of the flow guiding member 32 and the flow guiding member 32.

[0090] The specific implementation of this embodiment will be described below.

[0091] When water enters the interior of the housing 1 through the inlet 23, some water will directly impact the top surface 11 of the flow guide 32, and some water will flow along the edge of the inlet 23 to the first inner surface of the first flow guide wall 311.

[0092] Because a guide rib 34 is provided, and one end of the guide rib 34 near the inlet 23 contacts the guide member 32, one end of the guide rib 34 supports the guide member 32, and the guide member 32 is in contact with the inclined surface 3111 of the guide rib 34. Since the inclined surface 3111 is inclined from the inlet 23 side towards the bottom surface 12 of the tank 1 and towards the inner circumference of the inlet 23, when the water flow enters and impacts the top surface 11 of the guide member 32, it can suppress the noise generated by the guide member 32 moving and colliding with the inner circumference of the guide wall 31 due to the impact of the water flow.

[0093] Furthermore, the guide rib 34 protrudes from the guide surface 33 to the inner circumference to support the guide member 32, so that a certain gap 4 is maintained between the guide member 32 and the guide surface 33. After the water flows through the surface of the guide member 32, it can flow from the gap 4 between the guide member 32 and the guide surface 33 to the bottom surface 12 of the tank 1, and flow down along the guide surface 33 to the bottom surface 12 of the tank 1, thereby suppressing the noise generated by the water dripping directly from the inlet 23 and impacting the bottom surface 12 of the tank 1.

[0094] Fourth embodiment

[0095] The fourth embodiment of this utility model will be described below, wherein the same structure as the first to third embodiments will not be repeated.

[0096] In this embodiment, we continue to refer to... Figure 3 and Figure 4As shown, the first guide wall 311 also includes an inclined surface. That is, at least a portion of the first inner surface is inclined from the water inlet 23 side towards the bottom surface 12 of the tank 1 and towards the inner periphery of the water inlet 23. In other words, viewed from a direction parallel to the plane where the water inlet 23 is located, the inner periphery of the first guide wall 311 has a frustum-shaped cross section that is inclined towards the bottom surface 12 of the tank 1.

[0097] Furthermore, in this embodiment, the inclined surface is provided on the entire circumference of the first guide wall 311. That is to say, when viewed from any side 13 of the water tank, the cross-section of the inner circumferential space of the first guide wall 311 is frustum-shaped, and the angle between the side and the bottom of the frustum is not equal to 90 degrees.

[0098] Therefore, when the water tank is tilted, the guide 32 can quickly move to the first position under the guidance of the inclined surface, thereby quickly closing the water inlet 23 and further suppressing water from flowing out of the water tank from the water inlet 23.

[0099] Fifth Embodiment

[0100] The fifth embodiment of this utility model will be described below, wherein the same structure as in the first to fourth embodiments will not be repeated.

[0101] Figure 5 yes Figure 1 A partial cross-sectional view of the seal of the illustrative embodiment shown.

[0102] In this embodiment, as shown in Figure 5, the flow guide 3 further includes a sealing element 2, which is disposed on the upstream side of the flow guide 32 (i.e., the liquid flows through the sealing element 2 first and then through the flow guide 32), and the inlet 23 is disposed on the sealing element 2.

[0103] The seal 2 is used to seal the inlet 23 and includes a first seal 21 and a second seal 22.

[0104] The first sealing member 21 is provided with a water inlet 23. In this embodiment, the first sealing member 21 is cylindrical with a central opening and is provided on the top surface 11 of the water tank. It includes a top surface 11 near the top surface 11 of the water tank, a bottom surface 12 located on the opposite side of the top surface 11 and near the bottom surface 12 of the water tank, and a side surface 13 connecting the top surface 11 and the bottom surface 12. The water inlet 23 includes a first water inlet 231 provided on the top surface 11, a second water inlet 232 provided on the bottom surface 12, and an upper water inlet channel connecting the first water inlet 231 and the second water inlet 232.

[0105] The second seal 22 extends from the first seal 21 to the guide 32. Specifically, in this embodiment, the second seal 22 extends from the outer periphery of the second inlet 232 on the bottom surface 12 of the first seal 21 to the guide 32, including the top surface 11 connected to the bottom surface 12 of the first seal 21, and the bottom surface 12 located on the opposite side of the top surface 11.

[0106] The second seal 22 also includes a connecting port 24. The connecting port 24 is connected to the water inlet 23 and is located on the second seal 22 at the end away from the water inlet 23, that is, on the bottom surface 12 of the second seal 22. The second seal 22 also includes a lower water inlet channel connecting the second water inlet 232 and the connecting port 24.

[0107] In this embodiment, the diameter of the connecting port 24 is greater than or equal to the diameter of the inlet 23, and the diameter of the connecting port 24 is greater than or equal to the minimum diameter of the guide member 32. The second sealing member 22 is configured with a variable diameter portion located between the connecting port 24 and the inlet 23, with the position closer to the inlet 23 being the minimum diameter position and the position farther from the inlet 23 being the maximum diameter position.

[0108] The minimum diameter of the guide member 32 refers to the smallest diameter among the cross-sections of the guide member 32 that are at different distances from the inlet 23 in a direction parallel to the plane where the inlet 23 is located. In this embodiment, the guide member 32 is spherical, and the farther the sphere is from the center in a direction perpendicular to the plane where the inlet 23 is located, the smaller the diameter of the circular plane formed by its cross-section.

[0109] Furthermore, in this embodiment, the second sealing member 22 also includes an inclined sealing wall 221. The inclined sealing wall 221 is disposed on the inner peripheral wall of the lower water inlet channel of the second sealing member 22, extending from the side near the water inlet 23 to the side of the guide member 32, and is inclined towards the outer peripheral side of the water inlet 23. A communication port 24 is formed on the inclined sealing wall 221 near the edge of the guide member 32. That is, a communication port 24 is formed on one end of the inclined sealing wall 221 at the bottom surface 12 of the second sealing member 22.

[0110] The second inlet 232, the connecting port 24, and the inclined sealing wall 221 form a lower water inlet channel. In a direction parallel to the plane where the inlet 23 is located, the cross-section of the lower water inlet channel is trapezoidal, and the bottom edge of the trapezoid is located on the side close to the guide member 32.

[0111] Furthermore, in this embodiment, at least a portion of the second seal 22 is made of an elastic material. This elastic material includes, but is not limited to, rubber, silicone, and any other material suitable for adapting to the shape and / or pressure of the guide member 32.

[0112] The specific implementation of this embodiment will be described below.

[0113] When water enters the water tank through inlet 23, it first enters the upper inlet channel through the first inlet 231, and then flows into the lower inlet channel through the second inlet 232. At this time, the water will flow downward along the inner circumference of the second seal 22, that is, along the inner wall of the lower inlet channel, and flow out of the second seal 22 through the connecting port 24. Since the second seal 22 is located above the guide member 32, the water flowing out from the lower end of the second seal 22, i.e., the connecting port 24, will drip onto the guide member 32. Buffered by the guide member 32, the water will flow towards the bottom surface 12 of the tank body 1 through the second guide wall 312. This further suppresses water from dripping directly from the inlet 23 onto the guide member 32, thus preventing noise.

[0114] Furthermore, in this embodiment, the diameter of the connecting port 24 is set to be greater than or equal to the minimum diameter of the guide member 32. When the water tank tilts, the guide member 32 moves rapidly towards the inlet 23 side under the guidance of the first guide wall 311. When the guide member 32 contacts the bottom surface 12 of the second sealing member 22, that is, contacts the edge of the connecting port 24, since the diameter of the connecting port 24 is greater than or equal to the minimum diameter of the guide member 32, when the guide member 32 contacts the edge of the connecting port 24, a portion of the guide member 32 with a diameter less than or equal to the diameter of the connecting port 24 will penetrate the connecting port 24 and enter the lower water inlet channel, while the portion of the guide member 32 with a diameter greater than the diameter of the connecting port 24 will abut against the edge of the connecting port 24, thereby engaging and fixing it on the connecting port 24, so that the guide member 32 no longer moves towards the inlet 23 end. This allows for a better seal of the connecting port 24, which in turn seals the inlet 23, further reducing the risk of liquid inside the tank 1 flowing out of the tank 1 through the connecting port 24 and the inlet 23.

[0115] Furthermore, in this embodiment, at least a portion of the second seal 22 is made of an elastic material. Specifically, in this embodiment, the end of the second seal 22 near the connecting port 24 is made of an elastic material. When the guide member 32 abuts against the end of the second seal 22 near the connecting port 24, the second seal 22 will deform to a certain extent under the force applied by the guide member 32, so that the portion of the guide member 32 with a diameter less than or equal to the connecting port 24 can more smoothly pass through the connecting port 24 into the lower water inlet. When the guide member 32 moves to the point where the portion with a diameter greater than the connecting port 24 abuts against the edge of the connecting port 24, it will be locked and fixed on the connecting port 24. At this time, the deformed portion of the second seal 22 has the force to recover its deformation, which can further enable the guide member 32 to better seal the connecting port 24, thereby further reducing the outflow of water from the tank 1 through the connecting port 24 and the water inlet 23 to the outside of the tank 1.

[0116] Based on the same concept, this utility model also provides an air conditioning device, including a water tank, a drain outlet, a humidifier, and a water collection tray. The drain outlet is used to fill the water tank with water. The humidifier is used to humidify the air. The water collection tray is located below the humidifier, and the water inlet 23 of the water tank is located below the drain outlet.

[0117] An air conditioning device refers to a device used to regulate air, including but not limited to regulating the temperature, humidity, and quality of air. For example, it may reduce the relative humidity of the air through dehumidification, increase the relative humidity through humidification, or regulate the air temperature through total heat exchange, heat pumps, heaters, etc. The above examples are merely some examples of this utility model and do not represent a limitation on the air conditioning device of this utility model.

[0118] In some illustrative embodiments, the drain outlet can be located within the housing of the air conditioning unit, or in other structures within the housing. Specifically, the water inlet 23 of the water tank is located below the drain outlet to receive water injected through the drain outlet. The outlet end of the drain outlet and the inlet end of the water inlet 23 of the water tank can be positioned opposite each other, or they can be offset, and then connected by corresponding pipes. In this way, water can flow actively from the drain outlet into the inlet 23 by its own weight during flow. Of course, for different usage scenarios, a pump or other pressurization device can be installed between the drain outlet of the air conditioning unit and the inlet 23 of the water tank to pump water from the drain outlet into the water tank.

[0119] In this embodiment, the air conditioning device with a water tank has the same or similar technical features as the above embodiment. Based on this, water entering the water tank through the drain outlet 23 can be guided to reduce the distance between the guide wall 31 and the bottom surface 12 of the water tank, thereby suppressing noise. Other features of this embodiment are similar to those of the water tank described above, and therefore will not be repeated.
