Examples of these embodiments are illustrated 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.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0049] During air conditioning operation, warm indoor air is drawn in and flows through the evaporator. Water vapor in the air condenses into small water droplets, known as condensation, when it encounters the cold evaporator surface because its temperature is below the dew point. Air conditioners typically have a drip tray to collect this condensation. One end of a drain pipe connects to the drip tray, and the other end connects directly to the sewer, allowing the condensation to be discharged into the drain.

[0050] However, since the stale air in the sewer usually has an odor, this odor can flow back into the air conditioner through the drain pipe while the condensate is being drained, seriously affecting the user's experience. To prevent the odor from the sewer from flowing back into the air conditioner through the drain pipe, existing drain pipes are usually equipped with odor isolation valves. These valves allow the condensate to be drained through the drain pipe while isolating the odor from the sewer.

[0051] In related technologies, odor isolation valves typically include a housing, a separator, and a floating element. The housing has an inlet and an outlet, both of which are connected to a drain pipe. The separator is located inside the housing between the inlet and outlet and has a conical connecting groove. The floating element is spherical and movably connected to the connecting groove to either block or open it. Condensation from the air conditioner enters the housing through the inlet and flows into the connecting groove, accumulating there. When there is little condensation or the air conditioner is not draining, the floating element, under gravity, blocks the connecting groove, sealing the connection between the groove and the outlet, thus isolating the odor. When enough condensation accumulates in the connecting groove, the floating element floats, connecting the groove to the outlet and allowing the condensation to drain. After the condensation has drained, the floating element, under gravity, re-blocks the connecting groove, achieving odor isolation. However, since the floating part is usually spherical, the combination of the spherical floating part and the conical floating groove usually results in a large sealing water tension between the floating part and the conical floating groove, making it difficult for the floating part to float up and drain water. This may cause problems such as drainage difficulties during the operation of the odor isolation valve, affecting the user experience.

[0052] Based on the above analysis, this application provides an odor isolation valve. The odor isolation valve of this application will be described in detail below with reference to the accompanying drawings.

[0053] like Figures 1 to 13 As shown in the figure, this application embodiment provides an odor isolation valve, which includes: a housing 1, on which an inlet 101 and an outlet 102 are disposed opposite to each other, the inlet 101 and the outlet 102 being used to communicate with the drain pipe of an air conditioner; a partition plate 2, which is fixedly disposed inside the housing 1 and is located between the inlet 101 and the outlet 102, and a conical connecting groove 20 is provided on the side of the partition plate 2 near the inlet 101, the connecting groove 20 communicating with the inlet 101 and the outlet 102; and a conical floating member 3, which is movably connected to the connecting groove 20 to realize the switching of the connecting groove 20 between a conducting state and a closed state; wherein, in the closed state, there is an included angle between the floating member 3 and the connecting groove 20.

[0054] Specifically, such as Figures 1-8 As shown, the shell 1 is along the vertical direction ( Figure 5The housing 1 has an inlet 101 and an outlet 102 at opposite ends in the vertical direction. The inlet 101 is located at the top vertically of the housing 1, and the outlet 102 is located at the bottom vertically of the housing 1. The inlet 101 is connected to the air conditioner through the air conditioner's drain pipe, so that the condensate from the air conditioner can flow into the housing 1 through the inlet 101. The outlet 102 is connected to the sewer through the air conditioner's drain pipe, so that the condensate in the housing 1 can be discharged into the sewer.

[0055] The partition plate 2 is disposed inside the housing 1. The partition plate 2 is located between the liquid inlet 101 and the liquid outlet 102, and the partition plate 2 is fixedly connected to the inner wall of the housing 1. The fixed connection method includes, but is not limited to, bonding, snap-fitting, fastener connection, etc. Alternatively, the partition plate 2 and the housing 1 can also be integrally formed components. This application embodiment does not specifically limit this.

[0056] A connecting groove 20 is provided on the side of the partition plate 2 near the liquid inlet 101. The connecting groove 20 is a conical connecting groove 20, and a through hole is provided in the center of the connecting groove 20. The through hole is connected to the liquid inlet 101 and the liquid outlet 102, so that the connecting groove 20 is connected to the liquid inlet 101 and the liquid outlet 102.

[0057] The floating element 3 is a conical floating element 3, which is movably connected within the connecting groove 20 to enable the connecting groove 20 to switch between a conducting state and a closed state.

[0058] When condensate inside the air conditioner flows into the housing 1 through the liquid inlet 101, the condensate flows into the connecting groove 20 and accumulates there. For example... Figure 7 As shown, the arrow indicates the direction of odor flow. When there is little condensation in the connecting channel 20 or the air conditioner is not draining, the floating component 3 will be sealed in the connecting channel 20 under the action of gravity, making the connecting channel 20 closed. At this time, the connecting channel 20 and the liquid outlet 102 are sealed, achieving odor isolation. Figure 8 As shown, the arrow indicates the direction of condensate flow. When enough condensate accumulates in the connecting channel 20, the floating component 3 will move vertically upwards within the connecting channel 20 and float up, making the connecting channel 20 in a conductive state. At this time, the connecting channel 20 is connected to the liquid outlet 102, realizing the discharge of condensate. After the condensate is discharged, the floating component 3 moves vertically downwards under the action of gravity and re-seals the connecting channel 20, making the connecting channel 20 in a closed state again. At this time, the connecting channel 20 and the liquid outlet 102 are re-sealed, realizing odor isolation.

[0059] Among them, such as Figure 8As shown, the taper of the floating component 3 is different from that of the connecting groove 20. In the closed state, this creates an angle α between the connecting groove 20 and the floating component 3. When the condensate from the air conditioner enters the connecting groove 20, it can flow into the angle between the floating component 3 and the connecting groove 20, thus affecting the floating component 3. Figure 8 The buoyancy indicated by the arrow between the floating component 3 and the connecting channel 20 means that when enough condensation accumulates in the connecting channel 20, the floating component 3 will move vertically upwards within the connecting channel 20 and float up, thus making the connecting channel 20 conductive.

[0060] In this embodiment, by making the floating element 3 a conical floating element 3 and the connecting groove 20 a conical connecting groove 20, and by creating an angle between the floating element 3 and the connecting groove 20 in the closed state, condensate can enter between the floating element 3 and the connecting groove 20 through this angle. This reduces the water tension between the floating element 3 and the connecting groove 20, allowing the floating element 3 to float and drain more easily, simplifying the drainage of the odor isolation valve and improving the user experience. Furthermore, when scale builds up on the floating element 3 due to long-term use, the conical shape reduces scale adhesion to the float, and the conical shape facilitates scale sliding off, reducing clogging problems in the odor isolation valve and making it easier to clean.

[0061] Optionally, the included angle is α, where α satisfies: 20°-60°.

[0062] Specifically, such as Figure 7 As shown, there is an angle α between the connecting groove 20 and the floating component 3. In practical applications, when the angle α is too small, the initial water storage between the floating component 3 and the connecting groove 20 will be insufficient to generate buoyancy, making it difficult for the floating component 3 to float and drain water. When the angle α is too large, the initial water storage between the floating component 3 and the connecting groove 20 will be too large, easily leading to water accumulation. Furthermore, the upward force on the surface of the floating component 3 will decrease, also making it difficult for the floating component 3 to float and drain water.

[0063] In this embodiment, by making the included angle α satisfy 20°-60°, on the one hand, there can be enough initial water storage between the floating part 3 and the connecting groove 20, which is conducive to generating enough buoyancy so that the floating part 3 can float more easily and drain water. On the other hand, it can avoid the problem of water accumulation caused by excessive initial water storage, increase the upward force on the surface of the floating part 3, so that the floating part 3 can float more easily and drain water, thereby making the drainage of the odor isolation valve simpler and improving the user experience.

[0064] In some alternative embodiments, such as Figure 1 and Figure 2 As shown, the housing 1 may include a first flange 104, a second flange 105, and a cylindrical body 106, with the first flange 104 disposed on the cylindrical body 106 along the vertical direction. Figure 1 and Figure 2 At the upper end of the shell 106 (vertical direction), a first flange 104 is provided with a liquid inlet 101. The first flange 104 can be a cylindrical body. The first flange 104 is used to connect with the drain pipe of the air conditioner to the air conditioner through the drain pipe. A second flange 105 is provided at the lower end of the shell 106 in the vertical direction. The second flange 105 is provided with a liquid outlet 102. The second flange 105 can also be a cylindrical body. The second flange 105 is used to connect with the drain pipe of the air conditioner to the sewer through the drain pipe. In this way, during assembly, the air conditioner drain pipe can be fitted onto the first flange 104 and the second flange 105, which facilitates the connection between the shell 1 and the air conditioner drain pipe.

[0065] The first flange 104 and the second flange 105 can be integrally formed with the cylinder 106, or the first flange 104 and the second flange 105 can be detachably connected with the cylinder 106, or the first flange 104 and the second flange 105 can be connected to the cylinder 106 by means of snap-fit, threaded connection or other means. This application does not make specific limitations on this.

[0066] Optionally, it also includes a first guide post 4 and a first bracket 5. The first bracket 5 is fixedly disposed inside the housing 1 at one end near the liquid outlet 102 and spaced apart from the partition plate 2. The first bracket 5 is connected to the liquid outlet 102 and the connecting groove 20. The first bracket 5 is provided with a first mounting hole 50. One end of the first guide post 4 passes through the connecting groove 20 and is connected to the side of the floating member 3 near the liquid outlet 102. The other end of the first guide post 4 is movably disposed in the first mounting hole 50. The first guide post 4 is used to guide the movement of the floating member 3.

[0067] Specifically, such as Figure 4 and Figure 5 As shown, the first bracket 5 is disposed inside the housing 1 at one end near the liquid outlet 102 and is fixedly connected to the inner wall of the housing 1. The fixed connection method includes, but is not limited to, bonding, snap-fitting, fastener connection, etc. Alternatively, the first bracket 5 and the housing 1 can also be integrally formed components. This application embodiment does not specifically limit this.

[0068] The first support 5 is provided with a plurality of first connecting holes in its circumference. The first connecting holes are connected to the liquid outlet 102 and the connecting groove 20, so that the condensed water can pass through the connecting groove 20, the first connecting holes on the first support 5 and the liquid outlet 102 and be discharged from the housing 1.

[0069] A first mounting hole 50 is provided at the middle position corresponding to the connecting groove 20. The diameter of the first mounting hole 50 is slightly larger than the diameter of the first guide post 4, so that one end of the first guide post 4 can pass through the first mounting hole 50 and move vertically within the first mounting hole 50. The other end of the first guide post 4 can pass through the connecting groove 20 and be fixedly connected to the side of the floating member 3 near the liquid outlet 102. The first guide post 4 can be fixedly connected to the floating member 3 by snap-fit ​​or threaded connection, or the floating member 3 and the first guide post 4 can be an integrally formed component.

[0070] In practical applications, by setting the first guide post 4, when the floating part 3 moves up and down in the vertical direction, the first guide post 4 can follow the floating part 3 to move up and down. The first guide post 4 can guide the movement of the floating part 3, reduce leakage and wear problems caused by the offset of the floating part 3, and extend the service life of the odor isolation valve.

[0071] Optionally, the first guide post 4 is rotatable within the first mounting hole 50; the odor isolation valve also includes a rotating member 6, which is connected to the first guide post 4, is located between the floating member 3 and the first bracket 5, and covers the first mounting hole 50. The rotating member 6 is used to drive the first guide post 4 to rotate, thereby driving the floating member 3 to rotate.

[0072] Specifically, such as Figures 4-10 As shown, the rotating component 6 can be fixedly connected to the first guide post 4 by snap-fit ​​or threaded connection, or the rotating component 6 can be a one-piece molded component. The rotating component 6 can be a screw, axial flow blade, windmill, or other structure.

[0073] In practical applications, due to environmental factors such as humid environments and areas with poor air quality, microorganisms can easily accumulate in the condensate of air conditioners, leading to the formation of moss, scale, or gel-like deposits. These deposits are sticky and can adhere to the floating part 3 within the connecting groove 20, preventing the odor isolation valve from draining and causing it to malfunction. In such cases, external equipment such as a high-pressure water gun is required. Figure 12 As shown, the black arrow indicates the flow path of the high-pressure water. High-pressure water is supplied from the outlet 102 into the housing 1. The high-pressure water pushes the floating part 3 to separate from the connecting groove 20, so that the odor isolation valve can be cleaned, that is, the inside of the odor isolation valve is backwashed, thereby avoiding the need to disassemble and clean the odor isolation valve, and facilitating the cleaning operation of the odor isolation valve.

[0074] In this embodiment, by providing a rotating component 6, when the odor isolation valve is rinsed with a high-pressure water gun, the high-pressure water causes the rotating component 6 to rotate. The rotation of the rotating component 6 drives the first guide post 4 to rotate, which in turn drives the floating component 3 to rotate. The dirt on the surface of the floating component 3 is quickly washed away by the rotating water flow, which can improve the cleaning effect and speed of the odor isolation valve. Furthermore, by having the rotating component 6 cover the first mounting hole 50, it can prevent condensation water from flowing between the first mounting hole 50 and the first guide post 4 and accumulating scale and other deposits over a long period of time, thus affecting the rotation of the first guide post 4.

[0075] Optionally, the rotating component 6 includes a plurality of rotating blades 60, which are disposed on the outer peripheral wall of the first guide post 4 and spaced apart along the circumference of the first guide post 4.

[0076] Specifically, the rotating component 6 includes multiple rotating blades 60. For example, the number of rotating blades 60 can be 2, 3, 4, etc., and this embodiment does not specifically limit this. The multiple rotating blades 60 are distributed at intervals on the outer peripheral wall of the first guide post 4. The rotating blades 60 can be of any shape, such as streamlined blades or flat blades. In some optional embodiments, each rotating blade is streamlined, similar to a waterwheel blade or propeller structure, and its radial extension direction forms a certain helical angle with the axis of the first guide post, such as 15°-30°, to optimize the rotation efficiency during water flow impact.

[0077] The rotating blade 60 can be fixed to the outer peripheral wall of the first guide post 4 by means of snaps, threads, etc., or it can be integrally formed with the first guide post 4. This application embodiment does not specifically limit this.

[0078] In practical applications, by setting multiple rotating blades 60, compared with a single rotating blade 60, the total surface area in contact with the water flow is increased, thereby generating a larger torque at the same water flow speed. This allows the floating part 3 to rotate quickly, which can more efficiently convert the impact energy of the high-pressure water flow into the rotational motion of the floating part 3. This allows the dirt on the surface of the floating part 3 to be washed away quickly by the rotating water flow, further improving the cleaning effect and speed of the odor isolation valve.

[0079] Optionally, an overflow hole 103 is provided on the side of the housing 1 near the liquid inlet 101, and the overflow hole 103 is connected to the connecting groove 20.

[0080] Specifically, such as Figures 1-13 As shown, an overflow hole 103 is provided on the side of the housing 1 near the liquid inlet 101. The overflow hole 103 can be any shape, such as rectangular or circular. The overflow hole 103 is connected to the connecting groove 20, and the connecting groove 20 is connected to the liquid outlet 102. Figure 12As shown, during the backwashing operation of the odor isolation valve, high-pressure water flows into the connecting groove 20 inside the housing 1 through the outlet 102. The high-pressure water pushes the floating element 3 to separate from the connecting groove 20 and then flows through the connecting groove 20 to be discharged from the overflow hole 103. Alternatively, high-pressure water can be used to flush the pipes on the indoor side. High-pressure water flows into the housing 1 from the inlet 101 and then flows out from the overflow hole 103. During the flow, some of the dirt can be discharged from the overflow hole 103.

[0081] In this embodiment, by providing an overflow hole 103, high-pressure water and the contaminants it carries can flow out through the overflow hole 103, preventing the high-pressure water from carrying contaminants onto the air conditioner, thus improving user experience and extending the air conditioner's lifespan. Furthermore, when the odor isolation valve is blocked, condensate can be discharged through the overflow hole 103, allowing users to continue using the air conditioner briefly and preventing disruption to their lives during maintenance.

[0082] Optionally, there are multiple overflow holes 103, and the multiple overflow holes 103 are arranged at intervals along the circumference of the housing 1.

[0083] like Figure 3 As shown, there are multiple overflow holes 103. The number of overflow holes 103 can be 2, 3, 4, etc. This application embodiment does not make a specific limitation. The multiple overflow holes 103 are spaced apart and evenly arranged along the circumference of the housing 1.

[0084] In practical applications, by setting multiple overflow holes 103, high-pressure water and the contaminants it carries can flow out through these holes, further preventing contaminants from being carried onto the air conditioner by the high-pressure water flow, thus improving user experience and extending the air conditioner's lifespan. Furthermore, when the odor isolation valve is blocked, condensate can be discharged through the multiple overflow holes 103, allowing users to continue using the air conditioner briefly and avoiding disruption to their lives during maintenance.

[0085] Optionally, it also includes a baffle 11, one end of which is rotatably connected to the housing 1, and the other end is covered by the overflow hole 103.

[0086] Specifically, such as Figure 13 As shown, a baffle 11 is provided on the housing 1. One end of the baffle 11 is rotatably mounted on the housing 1, and the other end is covered above the overflow hole 103.

[0087] In practical applications, by setting baffle 11, the baffle 11 can close the overflow hole 103 under normal use. When overflow is needed, the baffle 11 can be directly opened by high pressure water to achieve overflow. The baffle 11 can prevent external impurities such as dust and insects from entering the housing 1 through the overflow hole 103 and being input into the indoor air conditioner through the odor isolation valve, thereby improving the customer experience.

[0088] It should be noted that the number of baffles 11 is the same as the number of overflow holes 103, so that multiple baffles 11 can block multiple overflow holes 103.

[0089] Optionally, the odor isolation valve also includes a second bracket 7 and a second guide post 8. The second bracket 7 is fixedly disposed inside the housing 1 at one end near the liquid inlet 101 and spaced apart from the partition plate 2. The second bracket 7 is connected to the liquid inlet 101 and the connecting groove 20. The second bracket 7 is provided with a second mounting hole 70. One end of the second guide post 8 is connected to the floating member 3, and the other end of the second guide post 8 is rotatably inserted through the second mounting hole 70.

[0090] Specifically, such as Figures 3-10 As shown, the second bracket 7 is disposed inside the housing 1 at one end near the liquid inlet 101 and is fixedly connected to the inner wall of the housing 1. The fixed connection method includes, but is not limited to, bonding, snap-fitting, fastener connection, etc. Alternatively, the second bracket 7 and the housing 1 can also be integrally formed components. This application embodiment does not specifically limit this.

[0091] The second support 7 is provided with a plurality of second connecting holes in its circumference. The second connecting holes are connected to the liquid inlet 101 and the connecting groove 20, so that the condensed water can pass through the liquid inlet 101 and the second connecting holes on the second support 7 and flow into the connecting groove 20.

[0092] A second mounting hole 70 is provided at the middle position corresponding to the connecting groove 20 of the second bracket 7. The diameter of the second mounting hole 70 is slightly larger than the diameter of the second guide post 8, so that one end of the second guide post 8 can pass through the second mounting hole 70 and can rotate within the second mounting hole 70. The other end of the second guide post 8 can be fixedly connected to the side of the floating member 3 near the liquid inlet 101. The center lines of the first guide post 4 and the second guide post 8 can be arranged collinearly. The second guide post 8 can be fixedly connected to the floating member 3 by snap-fit ​​or threaded connection, or the floating member 3 and the second guide post 8 can be integrally formed components.

[0093] In practical applications, by setting a second guide post 8, when the floating part 3 moves up and down in the vertical direction, the second guide post 8 can move up and down with the floating part 3. When the floating part 3 rotates, the second guide post 8 can rotate with the floating part 3. The second guide post 8 can guide the movement of the floating part 3, improve the stability of the movement of the floating part 3, further reduce leakage and wear problems caused by the offset of the floating part 3, and extend the service life of the odor isolation valve.

[0094] Optionally, it also includes a water cap 9, a portion of the second guide post 8 extending out of the second mounting hole 70, the water cap 9 being disposed on the portion of the second guide post 8 extending out of the second mounting hole 70, and the water cap 9 covering the second mounting hole 70.

[0095] Specifically, such as Figures 6-11 As shown, a portion of the second guide post 8 extends out of the second mounting hole 70, and the water cap 9 can be fixedly connected to the portion of the second guide post 8 that extends out of the second mounting hole 70. The water cap 9 can be fixedly connected to the second guide post 8 by snap-fit ​​or threaded connection, or the water cap 9 and the second guide post 8 can be integrally formed components.

[0096] In practical applications, by setting a water cap 9 on the second guide post 8, which covers the second mounting hole 70, condensation water can be prevented from flowing between the second mounting hole 70 and the second guide post 8 and accumulating scale and other deposits over a long period of time, thus affecting the rotation of the second guide post 8.

[0097] Optionally, it also includes a blocking block 10, which is disposed on the second guide post 8, spaced apart from the second bracket 7, and located between the second bracket 7 and the floating member 3.

[0098] Specifically, such as Figure 5 As shown, the blocking block 10 can be fixedly connected to the second guide post 8. The blocking block 10 can be fixedly connected to the second guide post 8 by snap-fit ​​or threaded connection, or the blocking block 10 and the second guide post 8 can be integrally formed components.

[0099] The blocking block 10 is located between the second support 7 and the floating member 3, and there is a certain distance between the blocking block 10 and the second support 7. In practical applications, when the floating member 3 moves upward vertically under the action of buoyancy, the second guide post 8 drives the blocking block 10 to move upward synchronously. The blocking block 10 can be limited by the upper support, which can prevent the floating member 3 from floating too high and blocking the overflow hole 103, thus affecting the cleaning effect of the odor isolation valve and the overflow blocking function.

[0100] In summary, the odor isolation valve provided in this application embodiment has at least the following advantages:

[0101] In this embodiment, by making the floating element 3 a conical floating element 3 and the connecting groove 20 a conical connecting groove 20, and by creating an angle between the floating element 3 and the connecting groove 20 in the closed state, condensate can enter between the floating element 3 and the connecting groove 20 through this angle. This reduces the water tension between the floating element 3 and the connecting groove 20, allowing the floating element 3 to float and drain more easily, simplifying the drainage of the odor isolation valve and improving the user experience. Furthermore, when scale builds up on the floating element 3 due to long-term use, the conical shape reduces scale adhesion to the float, and the conical shape facilitates scale sliding off, reducing clogging problems in the odor isolation valve and making it easier to clean.

[0102] This application also provides a drain pipe, which includes the odor isolation valve as described above.

[0103] Specifically, the drain pipe consists of two sections. One end of the drain pipe is connected to the air conditioner, and the other end is sleeved with the first flange 104 of the odor isolation valve. The other drain pipe has one end sleeved with the second flange 105 of the odor isolation valve, and the other end connected to the sewer pipe, thus realizing the drainage of the air conditioner and the isolation of odors.

[0104] It should be noted that in this embodiment, the structure of the odor isolation valve is the same as that of the odor isolation valve described in any of the above embodiments, and its beneficial effects are similar, so it will not be described in detail here.

[0105] This application also discloses an air conditioner, which includes the drain pipe described above or the odor isolation valve as described in any of the above embodiments.

[0106] Specifically, the air conditioner may include, but is not limited to, a casing and an evaporator and a drip tray installed inside the casing. During use, indoor hot air is drawn in and flows through the evaporator. Water vapor in the air condenses into small water droplets, i.e., condensate, when it encounters the surface of the evaporator, as the temperature is below the dew point. The drip tray is located below the evaporator and is used to collect the condensate dripping from the evaporator surface. The drain pipe includes two sections. One end of the drain pipe is connected to the drip tray, and the other end is sleeved with the first flange 104 of the odor isolation valve. One end of the other drain pipe is sleeved with the second flange 105 of the odor isolation valve, and the other end is connected to the drain pipe, thereby realizing the drainage and odor isolation of the air conditioner.

[0107] It should be noted that in this embodiment, the structure of the odor isolation valve is the same as that of the odor isolation valve described in any of the above embodiments, and its beneficial effects are similar, so it will not be described in detail here.
