Abstract

A water tank (100) and an air conditioning device using same. The water tank (100) comprises: a tank body (10) configured to contain a liquid; and a water inlet (20) arranged at the top of the tank body (10) for the liquid to enter. The water tank (100) further comprises: a flow guide wall (30) protruding and extending from the edge side of the water inlet (20) towards a bottom surface (111) of the tank body (10), wherein the liquid entering the tank body (10) from the water inlet (20) can flow towards the bottom surface (111) of the tank body (10) along the surface of the flow guide wall (30). According to the water tank (100), since the flow guide wall (30) protrudes and extends towards the bottom surface (111) of the water tank (100), a water flow can flow towards the bottom surface (111) of the water tank (100) under the guidance of the flow guide wall (30), thereby suppressing the situation where, after entering the water tank (100) through the water inlet (20), the water flow directly impacts or drips onto the bottom surface (111) of the water tank (100) or the liquid surface from the top surface (121) of the water tank (100), generating water flow noise or dripping noise, and thus effectively suppressing the formation of noise.

Description

Water tank and air conditioning unit using it Technical Field

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

[0002] Water tanks used in air conditioning units have an inlet hole through which water flows directly into the tank. To increase the tank's capacity, the inlet hole is usually 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 hole will impact the bottom of the tank or the surface of the stored water from a height due to gravity, 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 a damp state of the cushioning material may lead to bacterial growth and unpleasant odors, affecting user experience. Summary of the Invention

[0053] For ease of explanation, water will be used as the storage liquid in the following embodiments.

[0054] The water tank 100 of this disclosure will be described in detail below with reference to Figures 1 to 6.

[0055] First Embodiment

[0056] This embodiment discloses a water tank 100, including a tank body 10, a water inlet 20, and a flow guide wall 30.

[0057] The housing 10 forms the outline of the water tank 100 and is used to contain liquid. It includes a bottom wall 11, which is downward in the direction of gravity under normal use; a top wall 12, which is upward in the direction of gravity and opposite to the bottom wall 11; and a side wall 13 connecting the top wall 12 and the bottom wall 11. The surface of the bottom wall 11 facing the top wall 12 is the bottom surface 111 of the housing 10, and the surface of the top wall 12 facing away from the bottom wall 11 is the top surface 121 of the housing 10. In this embodiment, the housing 10 is approximately hollow cuboid in shape, and the side wall 13 includes a first side wall, a second side wall opposite to the first side wall, a third side wall, and a fourth side wall opposite to the third side wall. In other embodiments, the housing 10 may be approximately hollow cylindrical or other shapes.

[0058] The inlet 20 is located at the top of the water tank 100, specifically on the top wall 12 of the water tank 100, for allowing liquid to enter the water tank 100. In this embodiment, the top of the water tank 100 has an opening, and the water tank 100 also includes a water tank cover that covers the opening. The water tank cover is detachably mounted on the tank body 10. The inlet 20 is located on the water tank cover. In other embodiments, the inlet 20 may also be located on the top surface 121 other than the water tank cover. In this embodiment, multiple side walls 13 of the tank body 10 enclose the aforementioned opening. Optionally, in other embodiments, the top wall 12 of the water tank 100 may also be integrally connected to the side walls 13.

[0059] Furthermore, in this embodiment, the inner diameter of the inlet 20 is greater than the inner diameter that generates surface tension in the water under the pressure produced by the minimum inlet flow rate. That is, when the minimum inlet flow rate is constant, the pressure it generates is constant, the diameter that generates surface tension in the water is R1, and the inner diameter of the inlet 20 is R2. R2 is greater than R1. When the inlet 20 has an irregular shape, or when there are multiple inlets 20 with different dimensions, and due to factors such as the minimum inlet flow rate, the inlet 20 has a minimum inner diameter and a maximum inner diameter. The minimum inner diameter refers to the minimum width of the inlet 20, and the maximum inner diameter refers to the maximum width of the inlet 20.

[0060] Optionally, the inner diameter R2 of the inlet 20 is greater than or equal to 0.5 mm, that is, the minimum inner diameter of the inlet 20 is 0.5 mm. When the inner diameter R2 of the inlet 20 is greater than or equal to 0.5 mm, when water droplets flow to the inlet 20, because the inner diameter R2 of the inlet 20 is greater than or equal to 0.5 mm, the water droplets will not disperse and flow downwards, but will gather and stick together, and flow away along the guide wall 30.

[0061] Furthermore, the inner diameter R2 of the inlet 20 is less than or equal to 5 mm, meaning the maximum inner diameter of the inlet 20 is 5 mm. Therefore, when water flows to the inlet 20, because the inner diameter R2 is less than or equal to 5 mm, a certain surface tension will be created at the inlet 20. Even if water splashes onto the side of the guide wall 30 opposite the inlet 20, it can still, under the action of surface tension, flow across the inlet 20 to one side of the guide wall 30, and thus flow downwards along the guide wall 30. This effectively prevents water from flowing away from the inlet 20 along one side of the guide wall 30.

[0062] Specifically, in this embodiment, the inner diameter R2 of the inlet 20 is 1mm.

[0063] Similarly, when the inlet 20 is in a regular shape, that is, when the inner diameter of the inlet 20 is constant and uniform, that is, when the width of the inlet 20 is constant and uniform, the inner diameter of the inlet 20 is greater than or equal to 0.5 mm and less than or equal to 5 mm.

[0064] A flow guide wall 30 is disposed inside the water tank 100, protruding from one edge of the inlet 20 toward the bottom surface 111 of the tank body 10, for guiding the liquid to flow toward the bottom of the water tank 100. The flow guide wall 30 includes a top end connected to the inner wall surface of the top wall 12 of the tank body 10 or the bottom surface 111 of the tank body 10, an end end located on the opposite side of the top end, and a surface connecting the top end and the end end. In this embodiment, the flow guide wall 30 is disposed on the top wall 12 of the tank body 10. Specifically, the flow guide wall 30 protrudes from the side of the water tank 100 cover where the inlet 20 is provided, and is in the form of a sheet protruding and extending from the edge of the inlet 20 toward the bottom surface 111 of the tank body 10. The surface of the flow guide wall 30 includes a first surface 301 and a second surface 302 located on the other side of the first surface 301. In other embodiments, the flow guide wall 30 may also be cylindrical or conical, etc. Liquid entering through inlet 20 can flow along the first surface 301 or the second surface 302 toward the bottom surface 111 of the housing 10.

[0065] The edge of the inlet 20 includes, but is not limited to, the outer periphery adjacent to the inlet 20, and may also include the area near the outer periphery of the inlet 20. In this embodiment, the guide wall 30 extends protruding from the outer periphery of the inlet 20 toward the bottom surface 111 of the water tank 100. In other embodiments, the guide wall 30 may also be positioned at a certain distance from the outer periphery of the inlet 20 in the radial direction.

[0066] Furthermore, in this embodiment, the guide wall 30 extends protruding from a portion of the outer peripheral edge of the inlet 20. In other embodiments, the guide wall 30 may also be disposed around a perimeter of the inlet 20.

[0067] Furthermore, in this embodiment, there is a preset distance H between the guide wall 30 and the bottom surface 111 of the tank 10, and the preset distance H is less than or equal to the lowest water level WL of the water tank 100. That is, 0 < H ≤ WL. The preset distance between the guide wall 30 and the bottom surface 111 of the tank 10 refers to the vertical distance between the end of the guide wall 30 and the bottom surface 111 of the tank 10. In this embodiment, the water tank 100 also includes a lowest water level sensor disposed inside the tank 10 for detecting the lowest water level. The distance H between the guide wall 30 and the bottom surface 111 of the tank 10 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.

[0068] The specific implementation of this embodiment will be described below.

[0069] In this embodiment, when water flows towards the inlet 20, it flows into the tank 10 through the inlet 20, flowing along the edge of the inlet 20 into the tank 10. Because the minimum inner diameter of the inlet 20 is larger than the inner diameter required to generate surface tension when water flows into the inlet 20 at the minimum flow rate, even at the minimum flow rate, the water will not form a water film at the inlet 20 due to surface tension and will not flow into the tank 100.

[0070] As water enters the water tank 100 through the inlet 20, it flows downwards along the inner circumferential wall of the inlet 20 under the influence of gravity. Since the guide wall 30 is located at the outer circumferential edge of the inlet 20, the water continues to flow downwards along the surface of the guide wall 30 after passing the lower end of the inner circumferential wall of the inlet 20. Because the guide wall 30 protrudes towards the bottom surface 111 of the water tank 100, the water flows towards the bottom surface 111 of the water tank 100 under the guidance of the guide wall 30. This prevents the water from directly impacting or dripping from the top surface 121 of the water tank 100 onto the bottom surface 111 or the liquid surface after entering the water tank 100 through the inlet 20, thus preventing the generation of water flow sounds or dripping sounds and the formation of noise.

[0071] Furthermore, in this embodiment, the guide wall 30 and the bottom surface 111 of the housing 10 are set at a preset distance, which can prevent interference between the guide wall 30 and the bottom surface 111 of the housing 10 due to manufacturing tolerances, thereby preventing deformation or breakage of the guide wall 30 due to compression. At the same time, it can suppress the risk that the guide wall 30 is too long, making demolding difficult, and that the strength of the guide wall 30 is reduced due to its thinness after demolding.

[0072] Meanwhile, the distance H between the guide wall 30 and the bottom surface 111 of the tank 10 is less than or equal to the minimum water level WL of the water tank 100. When the water stored in the water tank 100 reaches the minimum water level, the distance between the end of the guide wall 30 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, when the water flows down along the surface of the guide wall 30 until it detaches from the end of the guide wall 30 and drips down, because the distance between the end of the guide wall 30 and the liquid surface at the minimum water level is small, or the end of the guide wall 30 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 generated by the water flow impacting the liquid surface or the bottom surface 111 of the water tank 100.

[0073] Second Embodiment

[0074] The second embodiment of this disclosure will be described below, wherein the same structure as the first embodiment will not be repeated.

[0075] This embodiment discloses a water tank 100, including a tank body 10, a water inlet 20, and a flow guide wall 30.

[0076] The water inlet 20 is located on the top wall 12 of the tank 10 and serves as an opening for supplying water into the tank 10. In this embodiment, the water inlet 20 is circular; in other embodiments, the water inlet 20 may also be square or other polygonal shapes. Water flows into the tank 10 through the water inlet 20.

[0077] A flow guide wall 30 is disposed inside the water tank 100, protruding from one edge of the inlet 20 toward the bottom surface 111 of the tank body 10, and is used to guide the liquid to flow to the bottom of the water tank 100. Specifically, in this embodiment, the flow guide wall 30 is a cylindrical body protruding from the bottom surface 111 of the tank body 10 toward the inlet 20. The cylindrical body can be a cylinder with a constant cross-section or a cylinder with a variable cross-section. In other embodiments, the flow guide wall 30 can also be other columnar shapes, such as a cubic column.

[0078] Furthermore, in this embodiment, the end of the guide wall 30 away from the bottom surface 111 of the tank 10 is positioned at a certain distance from the edge of the inlet 20. Specifically, the end of the guide wall 30 and the edge of the inlet 20 are at a certain distance in the radial direction of the inlet 20, and water enters the tank 10 through the gap between the inlet 20 and the end of the guide wall 30. Alternatively, the end of the guide wall 30 and the edge of the inlet 20 are at a certain distance in the direction of gravity, and the end of the guide wall 30 is located on the outer periphery of the inlet 20, and water enters the tank 10 through the gap between the inlet 20 and the end of the guide wall 30.

[0079] The specific implementation of this embodiment will be described below.

[0080] In this embodiment, when water is injected into the tank 10 through the inlet 20, because there is a certain distance between the end of the guide wall 30 and the edge of the inlet 20, the water will enter the tank 10 through the gap between the inlet 20 and the end of the guide wall 30. Furthermore, since the guide wall 30 extends from the bottom surface 111 of the tank 10 towards the inlet 20, water will drip onto the guide wall 30 and flow along its surface towards the bottom surface 111 of the tank 10. This suppresses noise or water flow sounds caused by water dripping directly from the top surface 121 where the inlet 20 is located or impacting the bottom surface 111 of the tank 10. In addition, even if there is a certain distance between the end of the guide wall 30 and the inlet 20, when water droplets fall on the guide wall 30, the distance between the end of the guide wall 30 and the inlet 20 is smaller than the distance between the inlet 20 and the bottom surface 111 of the housing 10. Therefore, even if water droplets fall on the guide wall 30 and produce water droplet or water flow sound, it may be within the range of noise that is not easily noticed or acceptable.

[0081] Third Embodiment

[0082] The third embodiment of this disclosure will be described below, wherein the same structure as the first or second embodiment will not be repeated.

[0083] This embodiment discloses a water tank 100, including a tank body 10, a water inlet 20, and a flow guide wall 30.

[0084] The water inlet 20 is located at the top of the tank 10, supplying water into the interior of the tank 10. The water inlet 20 includes a first water inlet 201 and a second water inlet 202.

[0085] As shown in Figures 4 and 6, the first inlet 201 is located on one side of the guide wall 30, and the second inlet 202 is located on the other side of the guide wall 30, opposite to the first inlet 201. Specifically, in this embodiment, the guide wall 30 is a sheet-like body, including a first surface 301 and a second surface 302 facing each other. The first inlet 201 is located on the side where the first surface 301 of the guide wall 30 is located, and the second inlet 202 is located on the side where the second surface 302 of the guide wall 30 is located. That is, the first inlet 201 and the second inlet 202 are arranged to sandwich the guide wall 30. There can be multiple first inlets 201, or only one. In this embodiment, there are multiple first inlets 201, that is, the top of the housing 10 is provided with two or more first inlets 201. Similarly, there can be multiple second inlets 202, or only one. In this embodiment, there are multiple second water inlets 202, that is, the top of the housing 10 is provided with two or more second water inlets 202.

[0086] Similarly, in this embodiment, the multiple first water inlets 201 have the same shape and size. In other embodiments, the multiple first water inlets 201 may have different shapes or sizes. Likewise, the multiple second water inlets 202 may also have different shapes or sizes.

[0087] Optionally, both the first inlet 201 and the second inlet 202 are arc-shaped, and the multiple first inlets 201 are arranged in a circumferential interval, that is, the multiple first inlets 201 are arranged in a circumferential interval around a vertical axis, which is defined as the central axis of the water intake area, and the area where the inlets 201 are located is the water intake area. Along the direction perpendicular to the central axis, the second inlet 202 is located inside the first inlet 201, and the multiple second inlets 202 are also arranged in a circumferential interval around the central axis.

[0088] For example, four first inlets 201 are arranged in a circumferential pattern on one side of the first surface 301 of the guide wall 30, and four second inlets 202 are arranged in a circumferential pattern on one side of the second surface 302 of the guide wall 30. Accordingly, there are four guide walls 30, and the four first inlets 201, the four second inlets 202, and the four guide walls 30 are arranged in a one-to-one correspondence.

[0089] Along the circumferential direction of the guide wall 30, the first inlet 201 and the second inlet 202 can be staggered and arranged on opposite sides of the guide wall 30, or the first inlet 201 and the second inlet 202 can be arranged on opposite sides of the guide wall 30 respectively.

[0090] Furthermore, the area of ​​the second inlet 202 is smaller than the area of ​​the first inlet 201. The area of ​​the second inlet 202 refers to its water inlet area. When there are multiple second inlets 202, their area includes, but is not limited to, the total area of ​​all second inlets 202. When there are multiple first inlets 201, their area includes, but is not limited to, the total area of ​​all first inlets 201. Therefore, in this embodiment, the area of ​​the second inlet 202 being smaller than the area of ​​the first inlet 201 specifically means that the total area of ​​the multiple second inlets 202 is smaller than the total area of ​​the multiple first inlets 201. In other embodiments, it may also mean that the area of ​​at least one second inlet 202 is smaller than the area of ​​the first inlet 201.

[0091] Furthermore, in this embodiment, the guide wall 30 includes a guide surface for guiding water flow. The guide surface is disposed on the surface of the guide wall 30, and the guide surface includes a first surface 301 and a second surface 302.

[0092] Furthermore, the guide wall 30 is provided with reinforcing ribs 40 protruding from the guide wall 30.

[0093] As shown in Figures 2 and 6, the reinforcing rib 40 is a protruding rib extending from the guide wall 30, including a guide reinforcing rib 41 extending from the guide surface of the guide wall 30. Specifically, in this embodiment, the guide reinforcing rib 41 extends from the guide surface away from the guide surface and includes a first reinforcing rib 411 and a second reinforcing rib 412.

[0094] The first reinforcing rib 411 is a protruding rib that extends from the first surface 301 of the guide wall 30 away from the guide wall 30, and the second reinforcing rib 412 is a protruding rib that extends from the second surface 302 of the guide wall 30 away from the guide wall 30. Specifically, the first reinforcing rib 411 and the second reinforcing rib 412 are intersecting or even perpendicular to the first surface 301 or the second surface 302 of the guide wall 30. In other embodiments, the guide wall 30 may also be provided with only the first reinforcing rib 411 or the second reinforcing rib 412.

[0095] Furthermore, in this embodiment, the first reinforcing rib 411 or the second reinforcing rib 412 is located below the water inlet 20. "Located below the water inlet 20" means that when the water tank 100 is in normal use, in the direction of gravity, the first reinforcing rib 411 or the second reinforcing rib 412 is located below the orthogonal projection of the water inlet 20 or at its outer periphery. In other embodiments, as long as the reinforcing effect is achieved, the first reinforcing rib 411 or the second reinforcing rib 412 may not be located below the water inlet 20.

[0096] Specifically, in this embodiment, the extension line of the flow guiding rib 41 is perpendicular to the plane where the inlet 20 is located. In other embodiments, the flow guiding rib 41 may also be disposed obliquely on the flow guiding wall 30 relative to the plane where the inlet 20 is located.

[0097] In this embodiment, the flow guide wall 30 is provided with a first reinforcing rib 411 and a second reinforcing rib 412. In other embodiments, the flow guide wall 30 may also be provided with multiple first reinforcing ribs 411 and multiple second reinforcing ribs 412.

[0098] Furthermore, in this embodiment, the flow guiding rib 41 has an inclined wall that extends from the inlet 20 toward the bottom surface 111 of the housing 10 and slopes toward the flow guiding wall 30. The inclined wall is located at the end of the flow guiding rib 41 away from the flow guiding wall 30. In other words, when viewed from a direction parallel to the flow guiding surface, the flow guiding rib 41 is approximately triangular.

[0099] Furthermore, as shown in Figures 1 and 4, the box body 10 also includes a guide slope 50.

[0100] The top of the housing 10 is equipped with a flow guide slope 50, which is inclined towards the inlet 20. In this embodiment, the flow guide slope 50 is located on the outer periphery of the first inlet 201 and the second inlet 202, and is inclined towards the first inlet 201 and the second inlet 202. In this embodiment, the flow guide slope 50 forms part of the top of the housing 10. In other embodiments, the flow guide slope 50 may also start from the outer periphery of the top of the housing 10 and slope towards the inlet 20. The slope of the flow guide slope 50 is set according to actual needs, and the slope can be 30 degrees, 40 degrees, 45 degrees, etc.

[0101] The specific implementation of this embodiment will be described below.

[0102] In this embodiment, when water is injected into the tank 10 through the water inlet 20, since there are a first water inlet 201 and a second water inlet 202, water will enter the tank 10 simultaneously through the first water inlet 201 and the second water inlet 202. Thus, more water can enter the tank 10 in the same amount of time, improving the efficiency of water injection.

[0103] Furthermore, since the guide wall 30 extends protruding from one edge of the inlet 20 toward the bottom surface 111 of the tank 10, the first inlet 201 and the second inlet 202 are respectively located on both sides of the guide wall 30. Specifically, in this embodiment, the first inlet 201 is located on the side where the first surface 301 of the guide wall 30 is located, and the second inlet 202 is located on the side where the second surface 302 of the guide wall 30 is located. When water enters the tank 10 from the first inlet 201, it will flow along the first surface 301 of the guide wall 30 toward the bottom surface 111 of the tank 10. When water enters the tank 10 from the second inlet 202, it will flow along the second surface 302 of the guide wall 30 toward the bottom surface 111 of the tank 10. Therefore, the two sides of the guide wall 30 can be fully utilized to guide the water flow to the bottom surface 111 of the tank 10, which increases the water volume per unit time and suppresses the water flow from dripping directly from the top surface 121 of the tank 10 or impacting the bottom surface 111 of the tank 10, thus preventing noise.

[0104] Furthermore, since the tank 10 is provided with a guide slope 50 inclined towards the first water inlet 201 and the second water inlet 202, even if some water splashes onto the outer periphery of the first water inlet 201 and the second water inlet 202 during the process of filling water into the water inlet 20, it will be guided by the guide slope 50 to flow towards the first water inlet 201 or the second water inlet 202, and finally enter the interior of the tank 10 through the first water inlet 201 or the second water inlet 202. This effectively prevents water from accumulating on the top surface 121 of the tank 10.

[0105] Furthermore, since the guide wall 30 extends from the inlet 20 towards the bottom surface 111 of the tank 10, its length in this direction is relatively long and it is sheet-like. When the guide wall 30 collides with other parts inside the water tank 100, or during cleaning and maintenance, it may be damaged or even broken. Therefore, reinforcing ribs 40 are provided on the guide wall 30. When the guide wall 30 collides with other parts, the reinforcing ribs 40 can buffer some of the force, reducing the probability of damage to the guide wall 30.

[0106] Furthermore, the guide wall 30 is provided with guide reinforcing ribs 41, which can further enhance the strength of the guide wall 30 and reduce the probability of damage to the guide wall 30.

[0107] Furthermore, the reinforcing ribs 41 increase the area of ​​the guiding surface. When water enters the tank 10 from the first inlet 201 or the second inlet 202, since the first reinforcing ribs 411 or 412 are located below the inlet 20, most of the water flows downward along the first surface 301 and the second surface 302 of the guiding wall 30, and a portion of the water flows downward along the surfaces of the first reinforcing ribs 411 and / or the second reinforcing ribs 412. Thus, while increasing the strength of the guiding wall 30, the amount of water guided is also increased, preventing some of the water entering the tank 10 from the inlet 20 from dripping or impacting the bottom surface 111 of the tank 10 without flowing along the guiding wall 30, thus generating noise and further suppressing noise formation.

[0108] Furthermore, the flow-guiding reinforcing rib 41 has an inclined wall, which is shaped to converge towards the flow-guiding wall 30. Thus, the water flowing along the flow-guiding reinforcing rib 41 towards the bottom surface 111 of the tank 10 will be guided by the flow-guiding reinforcing rib 41 and converge onto the flow-guiding wall 30. After merging with the water flow on the surface of the flow-guiding wall 30, it will flow towards the bottom surface 111 of the tank 10. Therefore, the flow-guiding reinforcing rib 41 does not need to extend to cover the ends and tops of the flow-guiding wall 30, achieving both reinforcement and flow guidance while saving costs.

[0109] Fourth embodiment

[0110] The fourth embodiment of this disclosure will be described below, wherein structures that are the same as or similar to those in other embodiments will not be repeated.

[0111] This embodiment discloses a water tank 100, including a tank body 10, a water inlet 20, and a flow guide wall 30.

[0112] The top surface 121 of the housing 10 is provided with multiple water inlets 20, including but not limited to multiple first water inlets 201 and multiple second water inlets 202.

[0113] The guide wall 30 is located at the outer peripheral edge of the inlet 20. In this embodiment, the water tank 100 is provided with multiple guide walls 30. The multiple guide walls 30 are arranged circumferentially around the central axis.

[0114] In this embodiment, the water tank 100 also includes reinforcing ribs 40 disposed on the flow guide wall 30.

[0115] As shown in Figure 2, the reinforcing rib 40 includes a reinforcing connecting rib 42. The reinforcing connecting rib 42 is used to connect multiple flow guide walls 30 and is disposed between the multiple flow guide walls 30. In this embodiment, the reinforcing connecting rib 42 extends protruding from two sides of the flow guide wall 30 toward adjacent flow guide walls 30 and connects adjacent flow guide walls 30. In other embodiments, the reinforcing connecting rib 42 may also extend protruding from the flow guide surface of the flow guide wall 30 toward other flow guide walls 30 and connect to other flow guide walls 30.

[0116] For example, there are four guide walls 30. Both the guide walls 30 and the reinforcing ribs 42 are sheet-like bodies with a certain curvature. Along the direction parallel to the central axis, the length of the reinforcing ribs 42 is less than the length of the guide walls 30. The two adjacent sides of two adjacent guide walls 30 are connected as one unit by a reinforcing rib 42. Alternatively, the reinforcing ribs 42 can be narrow strip-like sheets, and the two adjacent sides of two adjacent guide walls 30 can be connected as one unit by multiple spaced reinforcing ribs 42.

[0117] For example, the reinforcing rib 42 intersects or is perpendicular to the second surface 302 of the guide wall 30, and the reinforcing rib 42 is formed by extending from the second surface 302 of one guide wall 30 toward the second surface 302 of another adjacent or nearby guide wall 30. Each guide wall 30 is connected to one or more other guide walls 30 through at least one reinforcing rib 42.

[0118] The specific implementation of this embodiment will be described below.

[0119] In this embodiment, the guide wall 30 extends from the inlet 20 towards the bottom surface 111 of the tank 10 and is a relatively long sheet. When the guide wall 30 collides with other parts inside the water tank 100, or during cleaning and maintenance, it may be damaged or even broken. Therefore, the reinforcing ribs 42 on the guide wall 30 are provided to enhance the overall strength of the multiple guide walls 30 and prevent the edges of the guide walls 30 from being damaged or even broken during collisions.

[0121] Fifth embodiment

[0122] The fifth embodiment of this disclosure will be described below, wherein structures that are the same as or similar to those in other embodiments will not be repeated.

[0123] As shown in Figures 7, 8 and 9, this embodiment discloses an air conditioning device using the above-mentioned water tank 100. The air conditioning device includes the water tank 100, and also includes an air inlet 210, an air outlet 220, a water supply unit, an air supply unit and an air conditioning unit.

[0124] Air inlet 210 is an opening for supplying air into the air conditioning unit. Air outlet 220 is an opening for supplying air out of the air conditioning unit.

[0125] In this embodiment, the air conditioning device also includes a housing 200 forming the outer contour. An air inlet 210 and an air outlet 220 are disposed on the housing 200 of the air conditioning device, and an air supply unit is used to blow air from the air inlet 210 to the air outlet 220. In other embodiments, the air inlet 210 and the air outlet 220 may also be located in other positions, such as the ceiling, and connected to the air supply unit via ducts.

[0126] An air conditioning unit is used to regulate one or more characteristics of air, such as temperature, humidity, and mass, and is located upstream of the air outlet 220. In this embodiment, the air conditioning unit has the function of regulating the humidity of the air flowing through it. Specifically, the air conditioning unit includes a humidification unit 400, which humidifies the air. In this embodiment, the humidification unit 400 includes a humidification filter. The humidification filter absorbs water, and when air flows through it, the water on the filter evaporates, thereby increasing the humidity of the air.

[0127] A water supply unit is located within the air conditioning unit and is used to supply water to the air conditioning unit. Liquid flowing from the water supply unit enters the water tank 100, including the water supply outlet. The phrase "liquid from the water supply unit enters the water tank 100" includes liquid from the water supply unit entering the water tank 100 indirectly or directly. In this embodiment, the liquid from the water supply unit flows through other components before entering the water tank 100, i.e., it enters the water tank 100 indirectly.

[0128] The water supply unit includes a water supply hole for liquid outflow. The area of ​​the water inlet 20 is larger than the area of ​​the water supply hole.

[0129] The air conditioning unit also includes a water collection tray 500, a drain outlet 230, and a humidification water circuit.

[0130] The water collection tray 500 is used to collect water discharged from the air conditioning unit. In this embodiment, the water collection tray 500 is located below the air conditioning unit and above the water tank 100.

[0131] The drain outlet 230 is used to fill the water tank 100 with water. In this embodiment, the drain outlet 230 is an opening provided on the water collection tray 500 and is connected to the water inlet 20 of the water tank 100. Specifically, the drain outlet 230 is opposite to the water inlet 20 of the water tank 100 and is located above the water inlet 20. In this embodiment, the drain outlet 230 is a circular opening provided on the water collection tray 500.

[0132] The water supply unit includes a water pump used to transport water from the water tank 100 to the air conditioning unit. In this embodiment, the water pump is located inside the water tank 100. In other embodiments, the water pump may also be located outside the water tank 100. In this embodiment, the water supply port is the water outlet port of the water pump. That is, the area of ​​the water inlet 20 is larger than the area of ​​the water outlet port of the water pump. When there are multiple water inlets 20, the area of ​​the water inlets 20 refers to the total area of ​​the water inlets 20 and the area of ​​one side of each water inlet 20. In this embodiment, the area of ​​the water pump outlet port is 16π square millimeters, and the total area of ​​the water inlets 20 is 255 square millimeters.

[0133] When there are multiple inlets 20 arranged in a ring, the area of ​​one side of an inlet 20 refers to the sum of the areas of the first inlet 201 and the second inlet 202 located on one side. In this embodiment, the area of ​​one side of an inlet 20 is 51 square millimeters.

[0134] Since the total area of ​​the inlet 20 is larger than the area of ​​the pump outlet, even if the pump supplies water at maximum power, the water flowing from the water supply section to the water tank 100 can smoothly enter the water tank 100 through the inlet 20, thereby suppressing the risk of water accumulating upstream of the inlet 20.

[0135] Furthermore, since the area of ​​one side of the inlet 20 is larger than the area of ​​the water pump outlet, even if the air conditioning unit is tilted or the water tank 100 is installed at an angle, causing the surface where the inlet 20 is located to be tilted relative to the ground, the water flow relative to the plurality of inlets 20 will be uneven. In other words, compared to inlets 20 in other locations, the water flow to one side of the inlet 20 will be greater. Because the area of ​​one side of the inlet 20 is larger than the area of ​​the water pump outlet, even if the inlet 20 is tilted, the water flowing to the inlet 20 can flow smoothly into the water tank 100, thereby preventing water from accumulating upstream of the inlet 20 and preventing water from overflowing from upstream of the inlet 20.

[0136] The humidifying water circuit is used to transport water from the water tank 100 to the air conditioning unit and then return it to the water tank 100. Specifically, when the air conditioning unit is running, the water in the water tank 100 is drawn out by the water pump and flows into the air conditioning unit. Part of the water will evaporate under the action of the air conditioning unit to humidify the air flowing through it, and part of the water will be discharged from the air conditioning unit, flow to the water collection tray 500, and then be discharged through the drain outlet 230 on the water collection tray 500 and enter the water tank 100 through the water inlet 20 on the water tank 100.

[0137] In this embodiment, the water collection tray 500, the humidification unit 400, and the water tank 100 are housed within the housing 200 of the air conditioning device. In other embodiments, the water collection tray 500, the humidification unit 400, or the water tank 100 may not be housed within the air conditioning device.

[0138] In this embodiment, the water tank 100 also includes a buffer section 60.

[0139] As shown in Figures 8 and 9, the buffer section 60 is located below the drain outlet 230, and the inlet 20 is located on the outer periphery of the buffer section 60. "Located below the drain outlet 230" means that, in the direction of gravity, the buffer section 60 is located below the orthographic projection of the drain outlet 230. In this embodiment, the buffer section 60 is circular; in other embodiments, the buffer section 60 may also be of other shapes.

[0140] Furthermore, in this embodiment, the water inlet 20 is located on the outer periphery of the buffer portion 60 and is annular. Annularity includes, but is not limited to, the water inlet 20 surrounding the buffer portion 60 in a ring shape.

[0141] In this embodiment, the water inlet 20 includes a plurality of first water inlets 201 and a plurality of second water inlets 202. The plurality of first water inlets 201 are arranged in a ring around the buffer portion 60, and similarly, the plurality of second water inlets 202 are arranged in a ring around the buffer portion 60.

[0142] The guide wall 30 is located on the outer periphery of the buffer section 60, and the second inlet 202 is located between the guide wall 30 and the buffer section 60.

[0143] In this embodiment, the first inlet 201 is approximately fan-shaped with its center located on one side of the buffer section 60. It includes a first inner curved surface close to the buffer section 60, a first outer curved surface located on the side of the first inner curved surface away from the buffer section 60, and a first side surface connecting the two ends of the first inner curved surface and the first outer curved surface.

[0144] The second inlet 202 is approximately fan-shaped with its center located on one side of the buffer section 60. It includes a second inner curved surface close to the buffer section 60, a second outer curved surface located on the side of the second inner curved surface away from the buffer section 60, and a second side surface connecting the two ends of the second inner curved surface and the second outer curved surface.

[0145] The guide wall 30 is disposed between the first inlet 201 and the second inlet 202. Specifically, the first surface 301 is curved along the first inner curved surface, and the second surface 302 is curved along the second outer curved surface. When viewed from the inlet 20 toward the bottom surface 111 of the housing 10, the guide wall 30 is approximately fan-shaped with its center located on one side of the buffer section 60.

[0146] In this embodiment, the water tank 100 is provided with multiple guide walls 30, and reinforcing ribs 42 are provided between adjacent guide walls 30. The reinforcing ribs 42 connect two adjacent sides of two adjacent guide walls 30, and also connect the top and surrounding area of ​​adjacent guide walls 30. The multiple guide walls 30 and the multiple reinforcing ribs 42 form a cylindrical shape surrounding the outer periphery of the buffer section 60. Along a direction parallel to the central axis, the length of the reinforcing ribs 42 is less than the length of the guide walls 30.

[0147] In this embodiment, the water tank 100 further includes a flow guide slope 50. The flow guide slope 50 is inclined from the outer periphery of the water inlet 20 toward the side of the water inlet 20. In this embodiment, the flow guide slope 50 is arranged around the circumference of the water inlet 20, which is arranged in a ring shape.

[0148] Furthermore, in this embodiment, the buffer portion 60 also includes a boss 61 extending protruding from the drain outlet 230, and there is a certain distance between the boss 61 and the drain outlet 230. The term "certain distance" refers to the existence of a gap between the boss 61 and the drain outlet 230. In this embodiment, the boss 61 and the drain outlet 230 are positioned at a certain distance in the direction of gravity.

[0149] Furthermore, in this embodiment, the outer peripheral edge of the boss 61 is provided with an inclined surface that slopes towards the water inlet 20. That is, viewed from the drain outlet 230 toward the water inlet 20, the buffer part 60 is composed of a disc, an approximately conical cylinder, a cylinder, and a hollow annular body connected in sequence.

[0150] In addition, in this embodiment, the air conditioning device also includes a switch 300 for controlling the opening or closing of the drain outlet 230.

[0151] As shown in Figures 8, 9 and 10, the switch 300 is located at the drain outlet 230 and is used to control the opening or closing of the drain outlet 230. It includes a sealing unit 310 and a moving unit 320.

[0152] A sealing unit 310 is used to seal the drain outlet 230 and is located above the drain outlet 230. The outer diameter of the sealing unit 310 is greater than or equal to the inner diameter of the drain outlet 230. In this embodiment, the sealing unit 310 includes a sealing plate 311 and a sealing edge 312. The sealing plate 311 is approximately the same shape as the drain outlet 230. In this embodiment, the drain outlet 230 is circular, and the sealing unit 310 is a circle concentric with the drain outlet 230. The sealing edge 312 is a protruding edge that extends from the outer periphery of the sealing plate 311 to a more outer periphery, and the sealing edge 312 is arranged around the circumference of the sealing plate 311. In this embodiment, the sealing edge 312 is inclined to the outer side of the sealing plate 311 and to the side away from the drain outlet 230 and the outer periphery. The side away from the drain outlet 230 refers to the side away from the drain outlet 230 in the direction of gravity when the air conditioning device is in normal use. In this embodiment, the sealing edge 312 is inclined above and around the drain outlet 230, that is, the diameter of the end of the sealing edge 312 away from the drain outlet 230 is greater than the diameter of the end of the sealing edge 312 close to the drain outlet 230.

[0153] The movable unit 320 is used to move the sealing unit 310 relative to the drain outlet 230. The movable unit 320 is connected to the sealing unit 310. In this embodiment, the movable unit 320 and the sealing unit 310 are movably connected; in other embodiments, the movable unit 320 may also be integrally connected to the sealing unit 310.

[0154] In this embodiment, the sealing unit 310 is further provided with a connection hole for connection with the movable unit 320. Specifically, the connection hole is located at the center of the sealing sheet 311. In this embodiment, the sealing unit 310 is made of elastic silicone material.

[0155] The movable unit 320 includes a protrusion 321. The protrusion 321 is a columnar body extending from the drain outlet 230 towards the inlet 20. In this embodiment, the protrusion 321 is cylindrical; in other embodiments, the protrusion 321 may also be other columnar shapes. The protrusion 321 includes a first end near the drain outlet 230 and a second end near the inlet 20. The movable unit 320 also includes a limiting part connected to the protrusion 321. The limiting part is used to fix the protrusion 321 in place. During the movement of the movable unit 320 towards the drain outlet 230, the limiting part can abut against the water collection tray 500, thus playing a limiting role.

[0156] In this embodiment, the protrusion 321 is located on the side of the sealing unit 310 facing the inlet 20, that is, on the side of the sealing sheet 311 facing the inlet 20. Specifically, in this embodiment, the first end of the protrusion 321 near the sealing sheet 311 penetrates the center of the sealing sheet 311, connecting the movable unit 320 to the sealing sheet 311. In other embodiments, the movable unit 320 may also be integrally connected to the sealing sheet 311, that is, the protrusion 321 extends from the sealing sheet 311 towards the inlet 20.

[0157] Furthermore, in this embodiment, when the drain outlet 230 is in a sealed state, the distance between the end of the protrusion 321 away from the sealing unit 310 and the sealing unit 310 is greater than the distance between the buffer portion 60 and the sealing unit 310. The sealed state refers to the state in which the sealing unit 310 seals the drain outlet 230. In this embodiment, when the drain outlet 230 is in a sealed state, the protrusion 321 and the buffer portion 60 are not in contact. The distance between the buffer portion 60 and the sealing unit 310 refers to the perpendicular distance between the surface of the buffer portion 60 and the surface of the sealing unit 310. That is, the straight-line distance H1 between the second end of the protrusion 321 and the sealing plate 311 is greater than the straight-line distance H2 between the buffer portion 60 and the sealing plate 311.

[0158] Furthermore, in this embodiment, the active unit 320 also includes an elastic element 322.

[0159] The elastic element 322 connects the sealing unit 310, the movable unit 320, and the drain outlet 230, and is located between the sealing unit 310 and the movable unit 320. Specifically, the elastic element 322 is located between the sealing plate 311 and the second end of the protrusion 321. Specifically, in this embodiment, the elastic element 322 is a spring, and a stop plate that engages with the spring is provided at the drain outlet 230. The spring is sleeved on the protrusion 321, with one end of the spring abutting against the stop plate at the drain outlet 230 and the other end of the spring abutting against the second end of the protrusion 321.

[0160] The specific implementation of this embodiment will be described below.

[0161] In this embodiment, when the air conditioning device is running, the water pump draws water from the water tank 100 and transports it to the air conditioning unit. A portion of the water comes into contact with the air flowing through the air conditioning unit and evaporates, humidifying the air. A portion of the water will be discharged from the air conditioning unit under gravity and collected by the water collection tray 500 before being discharged through the drain outlet 230.

[0162] Since the buffer section 60 is located below the drain outlet 230, when water is discharged from the drain outlet 230, it will first drip onto the buffer section 60. This prevents the water discharged from the drain outlet 230 from dripping directly into the inlet 20 and then directly onto the bottom surface 111 of the tank 10, thus avoiding noise.

[0163] Furthermore, since the buffer section 60 has a protrusion 61 protruding to the side of the drain outlet 230, the distance between the buffer section 60 and the drain outlet 230 is further shortened. When water is discharged downward from the drain outlet 230, it will first flow to the surface of the protrusion 61, and then flow downward along the protrusion 61. As a result, the noise generated by the water flowing onto the buffer section 60 will be further suppressed.

[0164] Since the first water inlet 201 and the second water inlet 202 are located on the outer periphery of the buffer section 60, that is, on the outer periphery of the boss 61, a portion of the water discharged from the drain outlet 230 will flow outward along the boss 61. When it flows to the second water inlet 202, it will flow downward along the second outer curved surface of the second water inlet 202, and under the action of the second surface 302 of the guide wall 30, it will flow to the bottom surface 111 of the box 10.

[0165] When the water flow rate is high, some water may flow outwards through the surface of the second inlet 202. Since the first inlet 201 is located on the outer periphery of the second inlet 202, water flowing into the tank 10 without passing through the second inlet 202 will flow towards the first inlet 201, and then along the first inner curved surface of the first inlet 201 to the guide wall 30. Guided by the first surface 301 of the guide wall 30, it will flow towards the bottom surface 111 of the tank 10. The first inlet 201 and the second inlet 202 improve the efficiency of water injection into the tank 10.

[0166] Meanwhile, some of the water discharged from the drain outlet 230 may splash outwards from the outer periphery of the protrusion 61 due to impact. Since the water tank 100 is also equipped with a guide slope 50, the splashed water is guided by the guide slope 50 and flows towards the first inlet 201. Furthermore, due to inertia, most of the water will flow towards the first inner curved surface of the first inlet 201 and along the guide wall 30. Guided by the first surface 301 of the guide wall 30, it will then flow towards the bottom surface 111 of the tank body 10.

[0167] Furthermore, since the outer peripheral edge of the boss 61 is provided with a bevel, it can better guide the water flow that drips or impacts the buffer part 60 to the water inlet 20.

[0168] When water enters the tank 10 through the inlet 20 and is guided to the bottom surface 111 of the tank 10 by the guide wall 30, the water level inside the tank 10 will gradually rise until it exceeds the lower end of the reinforcing rib 42 near the bottom surface 111 of the tank 10. In this embodiment, since the reinforcing rib 42 and the guide wall 30 form a downward-opening cylindrical shape, when the water level is higher than the lower end of the reinforcing rib 42, a sealed cylindrical space will be formed on the inner circumference of the guide wall 30. Without the second inlet 202, since air cannot circulate inside the cylindrical space, under the action of air pressure, even if the water level on the outer circumference of the guide wall 30 rises, the water level inside the cylindrical space cannot rise further. Therefore, the cylindrical space located on the inner circumference of the guide wall 30 inside the water tank 100 cannot be used for water storage, and with a fixed external dimension of the water tank 100, the volume of the water tank 100 will be reduced.

[0169] In this embodiment, the first inlet 201 and the second inlet 202 are located on both sides of the guide wall 30, that is, on the outer and inner circumferential sides of the guide wall 30, respectively. As a result, the cylindrical space can be connected through the second inlet 202, thereby avoiding the formation of a sealed space on the inner circumferential side of the guide wall 30 and increasing the volume of the water tank 100.

[0170] Furthermore, when the water level in the water tank 100 drops to the minimum level and needs to be quickly replenished, or when cleaning or maintaining the water tank 100, the water tank 100 needs to be removed from the air conditioning unit. When the water tank 100 is removed, there may still be residual water on the water collection tray 500 that has not been drained into the water tank 100 in time. Therefore, after the water tank 100 is removed, the water on the water collection tray 500 may flow downwards through the drain outlet 230 and drip onto the air conditioning unit's housing 200, which may then flow outside the air conditioning unit or even into the room.

[0171] In this embodiment, since the drain outlet 230 is provided with a switch part 300, when the water tank 100 is pulled out, the switch part 300 seals the drain outlet 230 to prevent water on the water collection tray 500 from flowing out of the drain outlet 230.

[0172] Furthermore, the switch unit 300 includes a sealing unit 310 and a movable unit 320 capable of moving the sealing unit 310 relative to the drain outlet 230, and the movable unit 320 includes a protrusion 321. Specifically, since the distance H1 between the second end of the protrusion 321 and the sealing unit 310 is greater than the distance H2 between the buffer part 60 and the sealing unit 310, when the water tank 100 is installed below the drain outlet 230, the second end of the protrusion 321 will interfere with the buffer part 60 of the water tank 100, and the protrusion 321 will be pushed upward by the buffer part 60. Since the protrusion 321 is connected to the sealing plate 311, it drives the sealing plate 311 to move upward relative to the drain outlet 230, creating a distance between the sealing plate 311 and the drain outlet 230. Therefore, when the water tank 100 is installed below the drain outlet 230, the drain outlet 230 will be opened, and the water in the water collection tray 500 will be discharged from the gap between the sealing unit 310 and the drain outlet 230, and then enter the water tank 100 through the water inlet 20.

[0173] Meanwhile, since the movable unit 320 also includes an elastic element 322, and the elastic element 322 is located between the second end of the protrusion 321 and the sealing plate 311, when the water tank 100 is installed below the drain outlet 230, the protrusion 321 is lifted by the buffer part 60, and the elastic element 322 is compressed and deformed by the pressure of the second end of the protrusion 321 and the drain outlet 230, thereby providing a part of the force to the sealing plate 311, so that the sealing plate 311 can move upward better, and prevent the sealing plate 311 from being locked too tightly with the drain outlet 230 and unable to open.

[0174] When the water tank 100 is removed from below the drain outlet 230, the protrusion 321 and the buffer part 60 no longer interfere with each other. Under the action of gravity, the protrusion 321 moves downward. Since the protrusion 321 is connected to the sealing plate 311, it drives the sealing plate 311 to move downward relative to the drain outlet 230. Because the outer diameter of the sealing unit 310 is greater than or equal to the inner diameter of the drain outlet 230, when the sealing unit 310 moves downward to the drain outlet 230, it will cover the drain outlet 230. Thus, when the water tank 100 is removed, the drain outlet 230 can be automatically sealed, thereby preventing water from the water collection tray 500 from flowing out of the drain outlet 230.

[0175] Furthermore, since the sealing unit 310 also includes a sealing edge 312, and the sealing edge 312 is provided from the outer peripheral edge of the sealing sheet 311 to the outer periphery, when the sealing unit 310 moves downward, the sealing edge 312 will cover the outer edge of the drain outlet 230, or even cover the outer peripheral side of the drain outlet 230, thereby better sealing the drain outlet 230 and preventing water from flowing out from the gap between the sealing sheet 311 and the drain outlet 230.

[0176] Furthermore, since the sealing edge 312 is inclined above and to the outer periphery of the drain outlet 230, when the sealing unit 310 moves downward, under the inclined guidance of the sealing edge 312, the sealing piece 311 and a part of the sealing edge 312 can be pushed into the interior of the drain outlet 230, producing an interference fit, thereby better sealing the drain outlet 230.

[0177] Furthermore, when the water tank 100 is removed, the protrusion 321 and the buffer 60 no longer interfere. Under the action of gravity, the protrusion 321 will move downward, and the compressed elastic element 322 will also be released. The elastic element 322 will generate a downward force, driving the sealing unit 310 downward to the drain outlet 230, and providing a downward force for the sealing unit 310. Thus, even if there is a lot of water remaining in the water collection tray 500 and the sealing unit 310 is relatively light, it prevents the sealing unit 310 from moving upward or deviating from the drain outlet 230 under the influence of the buoyancy or impact force of the water, thereby further suppressing water from flowing out of the drain outlet 230.

[0178] Sixth Embodiment

[0179] The sixth embodiment of this disclosure will be described below, wherein structures that are the same as or similar to those in other embodiments will not be repeated.

[0180] This embodiment provides an air conditioning device that uses the water tank 100 described above. The air conditioning device includes the water tank 100 described above.

[0181] In this embodiment, the drain outlet 230 is provided with a switch part 300.

[0182] The switch unit 300 is used to control the opening or closing of the drain outlet 230, and includes a sealing unit 310 and a moving unit 320.

[0183] The sealing unit 310 is located above the drain outlet 230 and includes a sealing plate 311 and a sealing edge 312.

[0184] The movable unit 320 is located below the sealing unit 310 and includes a protrusion 321 extending from the drain outlet 230 toward the inlet 20.

[0185] In this embodiment, the protrusion 321 is provided on the buffer part 60. Specifically, the protrusion 321 extends from the buffer part 60 to the side of the drain outlet 230, including a first end near the drain outlet 230 and a second end near the buffer part 60.

[0186] In the sealed state, the distance H1' between the first end of the protrusion 321 and the buffer portion 60 is greater than the distance H2' between the buffer portion 60 and the sealing unit 310. In this embodiment, the sealing plate 311 is located above the drain outlet 230.

[0187] The specific implementation of this embodiment will be described below.

[0188] When the water tank 100 is installed below the drain outlet 230, since the distance between the first end of the protrusion 321 and the buffer part 60 is greater than the distance between the buffer part 60 and the sealing unit 310, the first end of the protrusion 321 will interfere with the sealing unit 310. Specifically, the first end of the protrusion 321 will penetrate the drain outlet 230 and interfere with the sealing plate 311 located above the drain outlet 230, pushing the sealing plate 311 upward. A certain distance is generated between the sealing plate 311 and the drain outlet 230, forming a gap. The water in the water collection tray 500 can be discharged through the gap between the sealing plate 311 and the drain outlet 230.

[0189] When the water tank 100 is removed from the drain outlet 230, the protrusion 321 is also removed. At this time, the sealing unit 310 moves downward under the action of gravity and covers and seals the drain outlet 230. This prevents water from flowing out of the drain outlet 230.
