[0068] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0069] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0070] The drain valve 100 of the first aspect of the present invention is described below with reference to the accompanying drawings.

[0071] According to the drain valve 100 of this utility model embodiment, such as Figure 1 As shown, the drain valve 100 includes an insertion portion 100a and an external portion 100b. The drain valve 100 is adapted to be installed through the drain hole 201. The insertion portion 100a is adapted to extend into the inner space 200a of the drain hole 201, and the external portion 100b is adapted to be placed outside the outer space 200b of the drain hole 201. The drain valve 100 is used to drain water from the insertion portion 100a to the external portion 100b.

[0072] A drainage hole 201 is formed on the structural member 200. The two side spaces of the structural member 200 are the inner space 200a and the outer space 200b of the drainage hole 201, respectively. For example, the structural member 200 can be a plate-shaped member, with the inner space 200a and the outer space 200b of the drainage hole 201 on both sides in the thickness direction. Alternatively, the structural member 200 can be a bottom plate or a side plate of the chassis 300. For example, when the structural member 200 is the bottom plate of the chassis 300, the drainage hole 201 penetrates the bottom plate in the vertical direction, with the upper space of the bottom plate being the inner space 200a of the drainage hole 201 and the lower space being the outer space 200b of the drainage hole 201.

[0073] A drain valve 100 is installed through a drain hole 201. The extension portion 100a of the drain valve 100 extends into the inner space 200a of the drain hole 201, and the outer portion 100b of the drain valve 100 is located in the outer space 200b of the drain hole 201. By setting the drain valve 100 to drain water from the extension portion 100a to the outer portion 100b, the drain valve 100 can discharge water from the inner space 200a of the drain hole 201 to the outer space 200b of the drain hole 201.

[0074] Furthermore, the structure of the drain valve 100 allows for controllable drainage speed. For example, an empty flow channel 10, such as a micropore, can be formed on the drain valve 100, resulting in a slower drainage speed. This achieves both water storage and water discharge. Alternatively, the drain valve 100 can include a water-absorbing material that can absorb water through capillary action and slowly discharge it, thus achieving both water storage and water discharge. By designing the size, shape, and material of the water-absorbing material, a set discharge volume can be achieved within a unit time, making the drainage speed controllable.

[0075] Compared to solutions that leave the drain hole open, the drain valve 100 of this invention does not drain the water completely all at once, thus meeting certain water storage needs, such as when water needs to be stored to dissipate heat from the condenser. Compared to solutions that completely block the drain hole, the drain valve 100 of this invention can gradually drain the water when water storage is not needed, avoiding water accumulation that could lead to bacterial growth. Furthermore, by considering the design of the location and terrain of the drain hole 201, it can also achieve the effect of completely draining the water.

[0076] According to the drain valve 100 of this utility model embodiment, by installing the drain valve 100 at the drain hole 201, the water inside the drain hole 201 can be discharged to the outside of the drain hole 201 using the drain valve 100. The drainage speed can be controlled by the structure of the drain valve 100. Compared with the solution of directly opening the drain hole 201, the water will not be discharged completely all at once, which can meet certain water storage needs, such as when water needs to be stored to dissipate heat from the condenser. Compared with the solution of completely sealing the drain hole 201, when water storage is not needed, the water can be discharged gradually, avoiding water accumulation and problems such as bacterial growth.

[0077] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the drain valve 100 includes a valve seat 1 and a water-absorbing material 2. The valve seat 1 is adapted to be installed through the drain hole 201. The valve seat 1 includes a first seat portion 11 and a second seat portion 12. The extended portion 100a includes the first seat portion 11, and the external portion 100b includes the second seat portion 12. The water-absorbing material 2 is installed on the valve seat 1, and the drain valve 100 drains water through at least the water-absorbing material 2.

[0078] For example, the valve seat 1 is installed through the drain hole 201. The valve seat 1 can install and seal the drain hole 201. The valve seat 1 supports the installation arrangement of the water-absorbing material 2 and blocks the drain hole 201, thereby improving the situation where water leaks out from the gap between the drain hole 201 and the valve seat 1. Only the water-absorbing material 2 is used to discharge the water in the inner space 200a of the drain hole 201 to the outer space 200b, making the drainage more controllable.

[0079] The absorbent material component 2 is made of absorbent material. It utilizes capillary action to absorb and drain water, making the drainage speed controllable and easily meeting the requirement of achieving a fixed discharge volume per unit time. For example, the absorbent material component 2 can be felt, sponge, cotton, etc., which utilizes its tiny pores to form capillaries. Under the action of surface tension, the liquid rises along the pores, and the capillary action absorbs and drains water, making the drainage speed controllable.

[0080] Since the valve seat 1 passes through the drain hole 201, a part of the valve seat 1 belongs to the inserted part 100a and a part belongs to the external part 100b. The valve seat 1 includes a first seat 11 and a second seat 12. The inserted part 100a includes the first seat 11, which extends into the inner space 200a of the drain hole 201. The external part 100b includes the second seat 12, which is located outside the outer space 200b of the drain hole 201.

[0081] The water-absorbing material component 2 is installed on the valve seat 1. The position of the water-absorbing material component 2 is not limited. The water-absorbing material component 2 can be entirely part of the inserted part 100a, or it can be entirely part of the external part 100b. Alternatively, the water-absorbing material component 2 can be partly part of the inserted part 100a and partly part of the external part 100b.

[0082] The drain valve 100 can drain water solely through the absorbent material 2, for example, the drain channel formed on the valve seat 1 may be completely filled with the absorbent material 2; or the drain valve 100 can drain water through both the absorbent material 2 and the drain channel on the valve seat 1, for example, a portion of the drain channel formed on the valve seat 1 may not be completely filled with the absorbent material 2. Of course, this is not the only possibility; the drain valve 100 can also drain water using both the absorbent material 2 and other draining components on the valve seat 1, all of which are within the protection scope of this utility model.

[0083] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, a cavity 13 is formed inside the valve seat 1, such as Figure 4 , Figure 5 and Figure 6 As shown, an upstream opening 111 communicating with the cavity 13 is formed on the outer surface of the first seat portion 11, and a downstream opening 121 communicating with the cavity 13 is formed on the outer surface of the second seat portion 12, as shown. Figure 2 and Figure 3 As shown, at least a portion of the absorbent material 2 is disposed within the cavity 13.

[0084] A cavity 13 is formed inside the valve seat 1. The upstream port 111 connects the inner space 200a of the drain hole 201 to the cavity 13, and the downstream port 121 connects the outer space 200b of the drain hole 201 to the cavity 13. The valve seat 1 connects the inner space 200a and the outer space 200b of the drain hole 201. At least a portion of the water-absorbing material 2 is disposed in the cavity 13, which can controllably discharge water.

[0085] By placing part of the absorbent material component 2 inside the cavity 13, this connection method is more reliable. The absorbent material component 2 is not easy to separate from the valve seat 1, and the part of the absorbent material component 2 located inside the valve seat 1 can be protected by the valve seat 1, is not easy to deform, and has high drainage reliability.

[0086] In some embodiments of this utility model, such as Figure 6 and Figure 8 As shown, the first seat 11 is located at one end of the second seat 12 in the first direction X. The cavity 13 includes a mating hole 131 extending in the first direction X. The mating hole 131 penetrates the end face of the second seat 12 in the first direction X away from the first seat 11 to form a downstream opening 121. At least a portion of the water-absorbing material 2 passes through the mating hole 131.

[0087] The mating hole 131 extends along the first direction X and penetrates the second seat 12 on the side end face away from the first seat 11 in the first direction X. The processing of the mating hole 131 is simple. The water-absorbing material 2 can be inserted into the mating hole 131 from the downstream port 121 along the first direction X. The installation of the water-absorbing material 2 is convenient.

[0088] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, the first seat 11 includes a sealing part 117, which is located at the end of the mating hole 131 away from the downstream opening 121 in the first direction X.

[0089] The sealing part 117 blocks the space of the mating hole 131 away from the downstream opening 121 in the first direction X. Therefore, when the absorbent material 2 is inserted into the mating hole 131 from the downstream opening 121 along the first direction X, the sealing part 117 acts as a limit, preventing the absorbent material 2 from coming out along the first direction X away from the downstream opening 121, thereby improving the installation stability of the absorbent material 2. Furthermore, the sealing part 117, sealing one end of the absorbent material 2 in the first direction X, enhances the protective effect of the valve seat 1 on the absorbent material 2.

[0090] Furthermore, when the valve seat 1 is installed through the drain hole 201 along the direction from the second seat portion 12 to the first seat portion 11, the sealing portion 117 can also prevent the water-absorbing material 2 from coming out along the first direction X toward the direction away from the downstream outlet 121.

[0091] In some embodiments of this utility model, such as Figure 4 As shown, the cavity 13 also includes a connecting hole 132 extending in a direction perpendicular to the first direction X. The connecting hole 132 penetrates the outer surface of the first seat portion 11 to form an upstream opening 111. The connecting hole 132 communicates with the mating hole 131.

[0092] The connecting hole 132 extends in a direction perpendicular to the first direction X, and the valve seat 1 is easy to process. The connecting hole 132 penetrates the outer surface of the first seat portion 11 to form an upstream port 111. For example, there can be one or more upstream ports 111. When there is one upstream port 111, there is one connecting hole 132 and it extends in a second direction Y perpendicular to the first direction X. When there are two or more upstream ports 111, there are multiple connecting ports and they extend in a second direction Y and a third direction perpendicular to the first direction X, respectively, to form multiple upstream ports 111 on the outer surface of the first seat portion 11.

[0093] At least a portion of the absorbent material 2 passes through the mating hole 131, and the connecting hole 132 communicates with the mating hole 131. Water can flow in from the inner space 200a of the drain hole 201 through the connecting hole 132, and then be absorbed and drained by the absorbent material 2. Alternatively, the absorbent material 2 can also be partially inserted through the connecting hole 132. Water can flow in from the inner space 200a of the drain hole 201 through the upstream port 111 into the connecting hole 132, and then be absorbed and drained by the absorbent material 2. Alternatively, the absorbent material 2 can extend from the upstream port 111 to the outside of the valve seat 1. The absorbent material 2 can directly absorb water from the inner space 200a of the drain hole 201 and drain the water to the outer space 200b of the drain hole 201.

[0094] In some embodiments of this utility model, such as Figure 4 and Figure 6 As shown, the mating hole 131 extends along the first direction X, and the connecting hole 132 communicates with the end of the mating hole 131 that is away from the second seat portion 12 in the first direction X.

[0095] In other embodiments of this utility model, such as Figure 13 As shown, the mating hole 131 extends along the first direction X, and the connecting hole 132 communicates with the middle portion of the mating hole 131 in the first direction X. It is worth noting that, to more clearly illustrate the locations of the mating hole 131 and the connecting hole 132, Figure 13 The mating hole 131 and the connecting hole 132 are marked by using a dashed box.

[0096] In some embodiments of this utility model, such as Figure 4 and Figure 6As shown, the connecting hole 132 penetrates the first seat portion 11 along the second direction Y, so that the first seat portion 11 forms an upstream opening 111 on both sides in the second direction Y, and the second direction Y is perpendicular to the first direction X.

[0097] The connecting hole 132 extends through both sides of the first seat 11, facilitating processing and demolding. Compared to the design where the first seat only extends through one side in the second direction Y to form an upstream opening, and the other side in the second direction Y is blocked by the first seat, the first seat 11 of this utility model embodiment is transparent in the second direction Y, making it less likely for water to accumulate in the connecting hole 132. This can improve the situation of water accumulation causing dirt and is beneficial to improving drainage reliability.

[0098] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, the absorbent material 2 includes an upstream segment 21 extending along the first direction X and located within the first seat portion 11. A first plane 111a and a second plane 111b perpendicular to the first direction X are respectively made through the upstream opening 111 at both ends. The outer peripheral surface of the upstream segment 21 includes an absorbent portion 211 located between the first plane 111a and the second plane 111b. The area where the absorbent portion 211 is directly opposite to the upstream opening 111 is the exposed area 2111, and the area where the absorbent portion 211 is offset from the upstream opening 111 is the hidden area 2112. The hidden area 2112 is in clearance fit with the first seat portion 11.

[0099] Water flows in from the inner space 200a of the drain hole 201 through the upstream opening 111, contacts the water-absorbing part 211, and is absorbed by the water-absorbing material 2. Water then flows through the water-absorbing material 2 to the outer space 200b of the drain hole 201. The area directly opposite the water-absorbing part 211 and the upstream opening 111 is the exposed area 2111, where water can directly contact. However, by fitting a gap between the hidden area 2112 and the first seat 11, water can also flow in from the gap between the water-absorbing material 2 and the first seat 11, contacting the hidden area 2112. This allows the upstream end of the water-absorbing material 2 to absorb water more fully, improving drainage reliability.

[0100] In some embodiments of this utility model, such as Figure 10 and Figure 11 As shown, the first seat 11 is located at one end of the second seat 12 in the first direction X. The valve seat 1 has an overflow channel 14 extending from the first seat 11 to the second seat 12. An overflow inlet 112 communicating with the overflow channel 14 is formed on the outer surface of the first seat 11. An overflow outlet 122 communicating with the overflow channel 14 is formed on the outer surface of the second seat 12. The overflow inlet 112 is located away from the second seat 12 relative to the upstream outlet 111 in the first direction X.

[0101] The overflow channel 14 also connects the inner space 200a of the drain hole 201 and the outer space 200b of the drain hole 201. Water in the inner space 200a of the drain hole 201 can not only flow out through the absorbent material 2, but also be discharged to the outer space 200b of the drain hole 201 through the overflow channel 14.

[0102] By positioning the overflow inlet 112 away from the second seat 12 relative to the upstream outlet 111, when the water level in the inner space 200a of the drain hole 201 is low, the water level in the inner space 200a of the drain hole 201 is lower than the overflow inlet 112, and the drain valve 100 slowly discharges the water to meet certain water storage needs; while when the water level in the inner space 200a of the drain hole 201 is high, for example, when rain causes excessive water accumulation, the water level in the inner space 200a of the drain hole 201 is higher than the overflow inlet 112, and the drain valve 100 quickly discharges the water directly from the overflow channel 14 until the water level is lower than the overflow inlet 112, thereby improving the situation of excessive water accumulation.

[0103] By setting up the overflow channel 14, water can be quickly drained to a controllable level when there is too much water accumulation, thereby improving the overflow problem caused by excessive water accumulation and enhancing the drainage reliability of the drain valve 100.

[0104] In some embodiments of this utility model, such as Figure 11 and Figure 14 As shown, the overflow channel 14 extends through both end faces of the valve seat 1 along the first direction X, so as to form an overflow inlet 112 on the side of the first seat 11 away from the second seat 12, and an overflow outlet 122 on the side of the second seat 12 away from the first seat 11.

[0105] The overflow channel 14 extends along the first direction X, which facilitates the machining of the overflow channel 14 on the valve seat 1; and an overflow inlet 112 is formed on the side of the first seat portion 11 away from the second seat portion 12. The height of the overflow inlet 112 is the highest height of the drain valve 100, which can maximize the water storage in the inner space 200a of the drain hole 201 to meet the usage requirements.

[0106] In some embodiments of this utility model, such as Figure 13 and Figure 14 As shown, the valve seat 1 has an overflow channel 14, which extends through both end faces of the valve seat 1 along the first direction X. The mating hole 131 includes an upstream hole section 1311 located within the first seat portion 11. The overflow channel 14 is located on the periphery of the upstream hole section 1311 and is open towards the upstream hole section 1311 to communicate with it. Multiple overflow channels 14 are provided and spaced apart circumferentially along the upstream hole section 1311. Figure 10 As shown, the connecting hole 132 and the overflow channel 14 are alternately arranged circumferentially along the upstream hole section 1311.

[0107] The overflow channel 14 extends along the first direction X, making it easier to machine the overflow channel 14 on the valve seat 1 and reducing the machining difficulty; and the overflow channel 14 is arranged parallel to the connecting hole 132, which can reduce the interference between the overflow channel 14 and the mating hole 131 during the machining process.

[0108] The mating hole 131 includes an upstream hole section 1311 located in the first seat portion 11, and an overflow channel 14 located on the outer periphery of the upstream hole section 1311. The overflow channel 14 is connected to the upstream hole section 1311. Compared with isolating the overflow channel 14 from the upstream hole section 1311, this embodiment of the utility model makes it easier to process the overflow channel 14 on the valve seat 1 without reducing the drainage capacity of the overflow channel 14.

[0109] Multiple overflow channels 14 are provided circumferentially along the upstream hole section 1311. By providing multiple overflow channels 14, the drainage capacity of the drain valve 100 can be improved.

[0110] The connecting hole 132 extends in a direction perpendicular to the first direction X. The connecting hole 132 and the overflow channel 14 are alternately arranged in the circumference of the upstream hole section 1311. This can isolate the connecting hole 132 and the overflow channel 14, preventing water from being discharged directly from the overflow channel 14 through the connecting hole 132. This can meet the needs of water storage and make drainage more controllable.

[0111] In some embodiments of this utility model, such as Figure 10 and Figure 14 As shown, the upstream hole section 1311 penetrates the end face of the first seat 11 on the side away from the second seat 12 in the first direction X.

[0112] The upstream orifice 1311 penetrates the first seat 11, making it easier to machine the upstream orifice 1311 on the valve seat 1 and reducing the machining difficulty; and the overflow channel 14 is connected to the upstream orifice 1311. By opening the upstream orifice 1311, the water inlet channel area of ​​the overflow channel 14 can be increased, which is beneficial to improving the drainage efficiency of the overflow channel 14.

[0113] In some embodiments of this utility model, such as Figure 10 , Figure 13 and Figure 14 As shown, the mating hole 131 passes through both ends of the valve seat 1 along the first direction X, and the connecting hole 132 connects the mating hole 131 in the middle of the first direction X along a direction perpendicular to the first direction X. The water-absorbing material 2 passes through the mating hole 131, and both ends of the water-absorbing material 2 in the first direction X are flush with the surface of the valve seat 1 in the first direction X.

[0114] By passing the upstream hole section 1311 through the end face of the first seat 11 on the side away from the second seat 12 in the first direction X, the water-absorbing material 2 can communicate with the internal space of the drain hole 201 through the penetration of the upstream hole section 1311. This not only allows the water-absorbing material 2 to absorb water more fully, which is beneficial to improving drainage reliability, but also facilitates the installation of the water-absorbing material 2 and improves the assembly efficiency of the water-absorbing material 2.

[0115] In some embodiments of this utility model, such as Figure 13 As shown, the mating hole 131 is a straight hole with a circular cross-section, and the absorbent material 2 is a long hole with a circular cross-section. The absorbent material 2 and the mating hole 131 are interference fit.

[0116] The mating hole 131 is a straight hole with a circular cross-section. The circular cross-section refers to a continuous circle around the entire circumference, rather than a partially circular open annular shape. The mating hole 131 has a regular shape and is interference-fitted with the circular absorbent material 2. The mating hole 131 and the absorbent material 2 are stable and reliable. The absorbent material 2 is not easily deformed when it passes through the mating hole 131, resulting in high drainage reliability.

[0117] The absorbent material component 2 is long and narrow. It can be a flexible and bendable component or a rigid and inflexible component.

[0118] In some embodiments of this utility model, such as Figure 3 and Figure 11 As shown, the absorbent material component 2 is entirely located within the cavity 13.

[0119] The absorbent material 2 is entirely located within the cavity 13. The valve seat 1 can protect the absorbent material 2, making it less prone to deformation and thus improving drainage reliability.

[0120] In other embodiments of this utility model, such as Figure 15 As shown, a portion of the absorbent material 2 extends out of the valve seat 1 through the upstream port 111 and / or the downstream port 121.

[0121] The absorbent material 2 can extend directly out of the valve seat 1 and come into direct contact with the water in the inner space 200a of the drain hole 201. By extending the absorbent material 2 out of the valve seat 1, it is easy to cut the absorbent material 2. It is worth noting that the length of the absorbent material 2 will affect the drainage efficiency when it is absorbing and draining water.

[0122] This allows a portion of the absorbent material 2 to extend from the upstream port 111 and / or the downstream port 121 outside the valve seat 1, making it easier to cut the absorbent material 2 to control the discharge volume per unit time according to actual needs, thus achieving controllable and adjustable drainage volume.

[0123] In some embodiments of this utility model, such as Figure 16 As shown, the outer surface of the first seat 11 has a mounting groove 113, the absorbent material 2 is embedded in the mounting groove 113, and the second seat 12 has a drainage groove 123 that communicates with the mounting groove 113. The absorbent material 2 extends into the drainage groove 123, or is located outside the drainage groove 123 and drains through the drainage groove 123.

[0124] The absorbent material component 2 is disposed on the outer surface of the first seat 11, which can improve the water absorption speed of the absorbent material component 2 and facilitate the assembly of the absorbent material component 2.

[0125] The second seat 12 has a drainage groove 123, and the water-absorbing material 2 can extend to the drainage groove 123. The water-absorbing material 2 drains water to the outer space 200b of the drainage hole 201; or the water-absorbing material 2 can drain water to the drainage groove 123, and the water then drains through the drainage groove 123 to the outer space 200b of the drainage hole 201.

[0126] The drainage groove 123 can be provided on the outer surface of the second seat 12; or, as... Figure 16 As shown, the drainage groove 123 can also be provided on the inner side of the second seat 12; or, the drainage groove 123 can be partially provided on the outer surface of the second seat 12 and partially provided on the inner side of the second seat 12, which can be selected according to actual needs.

[0127] In some embodiments of this utility model, such as Figure 17 As shown, the drain valve 100 includes a valve seat 1, which is adapted to be installed through the drain hole 201. The valve seat 1 includes a first seat portion 11 and a second seat portion 12. The first seat portion 11 constitutes an inserted portion 100a, and the second seat portion 12 constitutes an external portion 100b. The drain valve 100 drains water through an empty flow channel 10 formed on the valve seat 1. Here, the empty flow channel 10 refers to a flow channel without any filling material.

[0128] Since the valve seat 1 passes through the drain hole 201, a portion of the valve seat 1 belongs to the inserted portion 100a, and a portion belongs to the external portion 100b. The valve seat 1 includes a first seat portion 11 and a second seat portion 12. The first seat portion 11 belongs to the inserted portion 100a and extends into the inner space 200a of the drain hole 201. The second seat portion 12 belongs to the external portion 100b and is located outside the outer space 200b of the drain hole 201. The valve seat 1 defines an empty flow channel 10, allowing the valve seat 1 to controllably discharge water from inside the drain hole 201 to the outside of the drain hole 201.

[0129] In some embodiments of this utility model, such as Figure 17As shown, the vacant flow channel 10 includes a first flow channel 15, which is formed inside the valve seat 1. A first water inlet 114 communicating with the first flow channel 15 is formed on the outer surface of the first seat portion 11, and a second water inlet 124 communicating with the first flow channel 15 is formed on the outer surface of the second seat portion 12.

[0130] The first flow channel 15 is connected to the first water inlet 114 and the second water inlet 124. Water in the inner space 200a of the drain hole 201 flows into the first flow channel 15 through the first water inlet 114 and is then discharged through the second water inlet 124. The valve seat 1 drains water through the first flow channel 15. The valve seat 1 has a simple structure, strong structural stability, and is conducive to reducing manufacturing costs.

[0131] In some embodiments of this utility model, such as Figure 17 As shown, multiple micropores are formed on the valve seat 1, which together form the first flow channel 15. The micropores extend to the outer surface of the second seat portion 12 to form the second water inlet 124. The drainage speed of the multiple micropores is relatively slow, making the drainage speed controllable and easily meeting the requirement of achieving a fixed discharge volume per unit time.

[0132] In some embodiments of this utility model, such as Figure 18 As shown, the vacant flow channel 10 includes a second flow channel 16, which includes a first sub-flow channel segment 161 formed on the outer surface of the first seat portion 11. The second flow channel 16 also includes a second sub-flow channel segment 162 formed on the second seat portion 12. The first sub-flow channel segment 161 and the second sub-flow channel segment 162 are in communication.

[0133] The first sub-flow channel section 161 is formed on the outer surface of the first seat portion 11. Water in the inner space 200a of the drain hole 201 can flow directly through the first sub-flow channel section 161 to the second sub-flow channel section 162, thereby being discharged to the outer space 200b of the drain hole 201.

[0134] By forming the first sub-flow channel section 161 on the outer surface of the first seat 11, it is easier to process and the occurrence of blockage of the first sub-flow channel section 161 can be reduced, which helps to improve drainage reliability.

[0135] In some embodiments of this utility model, such as Figure 18 and Figure 19 As shown, the first sub-flow channel section 161 is constructed as follows: it extends along the direction from the first seat 11 to the second seat 12 and is a plurality of sections that are spaced around the first seat 11; or, it extends along a spiral line around the first seat 11. The second sub-flow channel section 162 is constructed as follows: it is formed on the outer surface of the second seat 12; or, it is formed inside the second seat 12, and a third water inlet 125 communicating with the second sub-flow channel section 162 is formed on the outer surface of the second seat 12.

[0136] The first sub-flow channel section 161 extends along the direction from the first seat portion 11 to the second seat portion 12 to guide water to the external portion 100b. Multiple first sub-flow channel sections 161 are spaced around the first seat portion 11. By providing multiple first sub-flow channel sections 161, drainage capacity can be improved, and the occurrence of blockage in the first sub-flow channel sections 161 can be reduced. The first sub-flow channel section 161 can extend linearly along the direction from the first seat portion 11 to the second seat portion 12, or it can extend slightly at an angle along the same direction.

[0137] The first sub-flow channel section 161 can also extend along a spiral line around the first seat 11. The first sub-flow channel section 161 occupies a larger area on the outer surface of the first seat 11, which is beneficial to improving drainage reliability.

[0138] like Figure 19 As shown, the second sub-flow channel section 162 can be formed on the outer surface of the second seat portion 12. Water flows from the first sub-flow channel section 161 on the outer surface of the first seat portion 11 to the second sub-flow channel section 162 on the outer surface of the second seat portion 12, and flows out from the third water outlet 125, thereby completing the process of water discharge from the inner space 200a of the drain hole 201 to the outer space 200b of the drain hole 201. The valve seat 1 is installed through the drain hole 201, and the valve seat 1 partially seals the drain hole 201. The valve seat 1 forms a second flow channel 16 on the first seat portion 11 and the second seat portion 12, so that water can only be discharged from the second flow channel 16, making the drainage speed controllable.

[0139] like Figure 18 As shown, the second sub-flow channel section 162 can also be formed within the second seat portion 12. Water flows through the first sub-flow channel section 161 on the outer surface of the first seat portion 11 to the valve seat 1, and then flows into the second sub-flow channel section 162 within the second seat portion 12, finally flowing out from the third water inlet 125. This completes the process of water being discharged from the inner space 200a of the drain hole 201 to the outer space 200b of the drain hole 201. The valve seat 1 is installed through the drain hole 201 and acts as a seal. The valve seat 1 blocks the drain hole 201, improving the situation where water leaks out from the gap between the drain hole 201 and the valve seat 1. Only the second flow channel 16 is used to discharge water from the inner space 200a of the drain hole 201 to the outer space 200b, making the drainage more controllable.

[0140] In some embodiments of this utility model, such as Figure 3 and Figure 4As shown, the valve seat 1 is made of an elastic material. The outer diameter of the first seat portion 11 gradually decreases along the direction from the second seat portion 12 to the first seat portion 11. The outer diameter of the first seat portion 11 is the minimum circumscribed circle diameter of the cross-section of the first seat portion 11. The valve seat 1 forms an annular groove 17 by narrowing its diameter between the first seat portion 11 and the second seat portion 12. The valve seat 1 passes through the annular groove 17 and is inserted into the drain hole 201. The first seat portion 11 and the second seat portion 12 are adapted to abut against the two sides of the structural member 200 in which the drain hole 201 is formed.

[0141] A drain hole 201 is formed on the structural member 200. The two sides of the structural member 200 are the inner space 200a and the outer space 200b of the drain hole 201, respectively. The valve seat 1 passes through the drain hole 201, such that the first seat portion 11 is located in the inner space 200a of the drain hole 201, and the second seat portion 12 is located in the outer space 200b of the drain hole 201. The valve seat 1 is made of an elastic material, such as a rubber plug. When the valve seat 1 is installed through the drain hole 201, it can deform, which facilitates installation and repositioning. After assembly, the fit between the valve seat 1 and the drain hole 201 is more stable, and the sealing effect at the fit position is better.

[0142] The outer diameter of the first seat 11 is the minimum circumscribed circle diameter of the cross-section of the first seat 11. The outer diameter of the first seat 11 gradually decreases along the direction from the second seat 12 to the first seat 11. The cross-sectional area of ​​the first seat 11 decreases along the direction from the second seat 12 to the first seat 11. This facilitates the installation of the valve seat 1 through the drain hole 201 from the direction from the second seat 12 to the first seat 11.

[0143] The valve seat 1 is necked between the first seat portion 11 and the second seat portion 12 to form an annular groove 17. The cross-sectional area of ​​the end of the first seat portion 11 near the second seat portion 12 is larger than the area of ​​the drain hole 201, and the cross-sectional area of ​​the end of the second seat portion 12 near the first seat portion 11 is larger than the area of ​​the drain hole 201. After the first seat portion 11 passes through the drain hole 201, the first seat portion 11 and the second seat portion 12 respectively abut against the two sides of the structural member 200 in which the drain hole 201 is formed, and the valve seat 1 has strong installation stability.

[0144] In some embodiments of this utility model, such as Figure 20 As shown, the first seat 11 includes a seat body 11a and an elastic buckle 11b connected to the outer periphery of the seat body 11a. The elastic buckle 11b and the second seat 12 are adapted to abut against the two sides of the structural member 200 with the drain hole 201 respectively. A sealing ring 3 is sleeved on the valve seat 1, and the sealing ring 3 is located between the first seat 11 and the second seat 12.

[0145] A drain hole 201 is formed on the structural member 200. The two sides of the structural member 200 are the inner space 200a and the outer space 200b of the drain hole 201, respectively. The valve seat 1 passes through the drain hole 201, such that the first seat portion 11 is located in the inner space 200a of the drain hole 201, and the second seat portion 12 is located in the outer space 200b of the drain hole 201.

[0146] The elastic buckle 11b and the second seat 12 are adapted to abut against both sides of the structural member 200 with the drain hole 201, respectively, resulting in strong installation stability of the valve seat 1. Furthermore, a sealing ring 3 is fitted onto the valve seat 1, located between the first seat 11 and the second seat 12. The valve seat 1 is sealed to the drain hole 201 via the sealing ring 3, improving the situation where water leaks from the gap between the drain hole 201 and the valve seat 1. Water is only discharged from the inner space 200a of the drain hole 201 to the outer space 200b, making drainage more controllable.

[0147] The drain valve 100 according to a second aspect embodiment of the present invention is described below with reference to the accompanying drawings.

[0148] According to the drain valve 100 of this utility model embodiment, such as Figure 3 and Figure 6 As shown, the drain valve 100 includes a valve seat 1 and a water-absorbing material 2. The two end faces of the valve seat 1 in the first direction X are a first end face 1a and a second end face 1b, respectively. A mating hole 131 extending along the first direction X is formed in the valve seat 1. The mating hole 131 penetrates the second end face 1b to form a downstream port 121 on the second end face 1b. The valve seat 1 includes a side surface 1c connecting the first end face 1a and the second end face 1b. An upstream port 111 is formed on the side surface 1c. The upstream port 111 communicates with the mating hole 131. At least a portion of the water-absorbing material 2 passes through the mating hole 131.

[0149] The valve body provides support and protection, and the absorbent material 2 is installed on the valve body. A mating hole 131 extending in the first direction X is formed in the valve seat 1. The mating hole 131 penetrates the second end face 1b to form a downstream port 121 on the second end face 1b. An upstream port 111 is formed on the side surface 1c of the valve seat 1, and the upstream port 111 communicates with the mating hole 131.

[0150] Water flows into valve seat 1 through upstream port 111, flows through mating hole 131, and finally flows out from downstream port 121. By inserting water-absorbing material 2 through mating hole 131, the capillary action of water-absorbing material 2 is used to absorb and drain water, making the drainage speed controllable and easily meeting the requirement of achieving a fixed discharge volume per unit time.

[0151] According to the drain valve 100 of this utility model embodiment, water can be discharged in a controlled manner using the water-absorbing material 2. While storing and utilizing water, it can also discharge water, thus improving problems such as bacterial growth caused by water accumulation.

[0152] In some embodiments of this utility model, such as Figure 11 and Figure 13 As shown, the drain valve 100 has an overflow channel 14 extending along the first direction X. The overflow channel 14 penetrates the first end face 1a to form an overflow inlet 112 and penetrates the second end face 1b to form an overflow outlet 122. The overflow channels 14 are multiple ones arranged at intervals along the circumference of the mating hole 131. The upstream ports 111 are multiple ones arranged at intervals along the circumference of the mating hole 131. The multiple overflow channels 14 and the multiple upstream ports 111 are arranged alternately along the circumference of the mating hole 131.

[0153] Water can also flow into the overflow channel 14 through the overflow inlet 112, then flow through the overflow channel 14, and finally flow out through the overflow outlet 122. Thus, water can also flow out through the overflow channel 14 on the drain valve 100. By setting the overflow inlet 112 on the first end face 1a, and in the first direction X, the overflow inlet 112 is set further away from the second end face 1b than the upstream outlet 111. When there is little water, the liquid level does not exceed the first end face 1a, and the water is slowly discharged through the path of the upstream outlet 111, the mating hole 131, and the downstream outlet 121, which meets certain water storage needs. When there is a lot of water, the liquid level exceeds the first end face 1a, and the drain valve 100 directly discharges the water quickly from the overflow channel 14 until the water level is lower than the first end face 1a, thereby improving the situation of excessive water accumulation and overflow.

[0154] Multiple overflow channels 14 are provided at circumferential intervals along the mating hole 131. By providing multiple overflow channels 14, the drainage capacity of the drain valve 100 can be improved.

[0155] Multiple upstream ports 111 are spaced apart circumferentially along the mating hole 131, which helps improve the drainage stability of the drain valve 100. Multiple overflow channels 14 and multiple upstream ports 111 are alternately arranged circumferentially along the mating hole 131. The upstream ports 111 and overflow channels 14 can be isolated from each other, preventing water from flowing into the upstream ports 111 and being discharged directly from the overflow channels 14, which can meet the needs of water storage and make drainage more controllable.

[0156] In some embodiments of this utility model, the mating hole 131 can penetrate through the first end face 1a, and water can also enter the mating hole 131 from the first end face 1a and come into contact with the water-absorbing material 2; or the first end face 1a can also be closed at the corresponding mating hole 131, which can enhance the protection of the water-absorbing material 2 set in the mating hole 131.

[0157] In some embodiments of this utility model, such as Figure 13 As shown, the mating hole 131 is a straight hole with a circular cross-section, and the absorbent material 2 is a long hole with a circular cross-section. The absorbent material 2 and the mating hole 131 are interference fit.

[0158] The mating hole 131 is a straight hole with a circular cross-section, and the absorbent material 2 is an elongated circular cross-section. The circular cross-section refers to a continuous circle around the entire circumference, rather than a partially circular open annular shape. The mating hole 131 has a regular shape and an interference fit with the circular absorbent material 2. The fit between the mating hole 131 and the absorbent material 2 is stable and reliable. The absorbent material 2 is not easily deformed when inserted into the mating hole 131, resulting in high drainage reliability.

[0159] The absorbent material 2 can be a flexible, bendable component. For example, the absorbent material 2 can be a sponge, cotton thread, towel, etc. The tiny pores of the absorbent material 2 form capillaries, and the liquid rises along the pores under the action of surface tension, using capillary action to absorb and drain water, making the drainage speed controllable. Alternatively, the absorbent material 2 can also be a rigid, inflexible component. For example, the absorbent material 2 can be a plaster component with multiple tiny pores, which can slowly drain water.

[0160] Therefore, the drainage speed of the drain valve 100 in this embodiment of the present invention is controllable and adjustable, and it is easy to replace.

[0161] Furthermore, alternative embodiments of the drain valve 100 according to the second aspect of the present invention can all refer to the design of the drain valve 100 of the first aspect embodiment without contradiction. That is to say, the detailed features of the drain valve 100 according to some embodiments of the first aspect of the present invention are also applicable to the drain valve 100 of the second aspect embodiment without contradiction, so they will not be described in detail here.

[0162] The air conditioner 1000 of the third aspect of the present invention is described below with reference to the accompanying drawings.

[0163] According to an embodiment of the present utility model, the air conditioner 1000, such as Figure 21 As shown, a drain valve 100 includes any of the above-mentioned items.

[0164] According to the embodiment of the present utility model, the air conditioner 1000, by setting the above-mentioned drain valve 100, can play a certain role in water storage, can reuse the stored water, improve the energy efficiency of the air conditioner 1000, and by setting the above-mentioned drain valve 100, water can also be discharged, improving the problem of bacteria growth caused by water accumulation.

[0165] In some embodiments of this utility model, such as Figure 21As shown, the air conditioner 1000 includes an outdoor chassis 302a suitable for installation outdoors. The bottom wall and / or side wall of the outdoor chassis 302a have drain holes 201, and a drain valve 100 is detachably disposed at the drain hole 201. For example, the drain valve 100 can be inserted into the drain hole 201 from the outside to the inside of the outdoor chassis 302a, i.e., the drain valve 100 is positioned on the outside of the outdoor chassis 302a, with the first seat 11 facing the drain hole 201. By pushing the drain valve 100 along the direction from the second seat 12 to the first seat 11, the first seat 11 can enter the outdoor chassis 302a through the drain hole 201.

[0166] Water accumulation in the outdoor chassis 302a is not easily drained actively. By providing drainage holes 201 on the bottom and / or side walls of the outdoor chassis 302a and placing a drainage valve 100 at the drainage holes 201, it is easy to drain all the water accumulation in the outdoor chassis 302a and improve the problem of bacterial growth caused by water accumulation.

[0167] The drain valve 100 is detachably located at the drain hole 201. When the outer chassis 302a needs to store a certain amount of water to dissipate heat from the outdoor heat exchanger, the drain valve 100 is installed at the drain hole 201. This allows for the storage and utilization of water while also draining it, thus mitigating problems such as bacterial growth caused by water accumulation. When water storage in the outer chassis 302a is not required, the drain valve 100 can be removed from the drain hole 201, allowing the accumulated water on the outer chassis 302a to drain quickly and improving the dryness of the outer chassis 302a.

[0168] Therefore, the drainage speed of the drain valve 100 is controllable and adjustable, and it is easy to replace; moreover, the drain valve 100 is easy to install after-sales, and the installation can be determined according to the climate differences in different regions.

[0169] Air conditioner 1000 can be either a split type or an integrated type. If it is a split type air conditioner, the outer chassis 302a is the chassis of the outdoor unit of the split type air conditioner; if it is an integrated type air conditioner, the outer chassis 302a is the chassis of the outdoor part of the integrated type air conditioner.

[0170] In some embodiments of this utility model, such as Figure 21 and Figure 22As shown, the air conditioner 1000 is a window air conditioner and includes a chassis 300, a first heat exchanger 400, and a second heat exchanger 500. The chassis 300 includes a first chassis portion 301 suitable for installation indoors and a second chassis portion 302 suitable for installation outdoors. The second chassis portion 302 forms an outer chassis 302a. The first heat exchanger 400 is located above the first chassis portion 301, and the second heat exchanger 500 is located above the second chassis portion 302. An external water guide channel 3021 and a water storage tank 3022 are formed on the second chassis portion 302. The water storage tank 3022 is located below the second heat exchanger 500. The external water guide channel 3021 connects the water storage tank 3022 with the water outlet flow path 3011 of the first chassis portion 301. The drain hole 201 is connected to the water storage tank 3022 and is located at the end of the water storage tank 3022 away from the external water guide channel 3021.

[0171] The first chassis portion 301 has a water outlet path 3011. Condensate generated on the first heat exchanger 400 falls into the water outlet path 3011 under gravity. The condensate flows through the water outlet path 3011 and the external water guide trough 3021, eventually reaching the water storage tank 3022. The condensate in the water storage tank 3022 can be applied to the second heat exchanger 500, for example, by splashing or spraying it onto the second heat exchanger 500, accelerating the heat dissipation of the outdoor second heat exchanger 500. By utilizing the condensate generated by the first heat exchanger 400, the performance of the air conditioner 1000 is improved.

[0172] The drain hole 201 is connected to the water storage tank 3022. By installing the drain valve 100 at the drain hole 201, the drainage speed can be controlled by the structure of the drain valve 100 to achieve a fixed discharge volume per unit time. Compared with the solution of directly opening the drain hole 201, the water will not be discharged quickly and completely at once, thus meeting the heat dissipation requirements of the water storage for the second heat exchanger 500. Compared with the solution of completely sealing the drain hole 201, the water can be gradually discharged when the water storage is not needed, which can improve the problem of bacteria growth caused by water accumulation and reduce the situation of water flowing back into the room.
