DETAILED DESCRIPTION
[0031] For reference Figures 1 to 5As shown, according to the embodiment of the present application, the drain device comprises a base 1 and a first valve seat 2, the first valve seat 2 comprises a first valve port 3, a first valve cavity 4 is formed between the first valve seat 2 and the base 1, the cross section of the first valve cavity 4 gradually decreases along the direction close to the first valve port 3, a first floating ball 5 is arranged in the first valve cavity 4, the first floating ball 5 can float up under the action of the condensed water and block the first valve port 3.
[0032] With the drain device of the present application, the condensed water is collected at the bottom of the drain device, when the drain device is inclined, the condensed water will flow back, at this time, since the first floating ball 5 can float up under the action of the condensed water and the cross section of the first valve cavity 4 gradually decreases along the direction close to the first valve port 3, under the guidance of the first valve cavity 4 and the buoyancy of the condensed water, the first floating ball 5 floats along the side wall of the first valve cavity 4 to the first valve port 3 and blocks the first valve port 3 under the action of the buoyancy of the condensed water, thereby blocking the flow back path of the condensed water, effectively preventing the condensed water from overflowing from the water receiving tray to the outside when the water receiving tray is inclined, and improving the reliability of the water receiving tray.
[0033] In the embodiment, the first floating ball 5 is, for example, a hollow floating ball, which can reduce the material consumption of the first floating ball 5, reduce the cost, and at the same time, can improve the buoyancy of the first floating ball 5 and enhance the working performance of the first floating ball 5.
[0034] The base 1 is provided with a first drain port 6, the diameter of the first drain port 6 is smaller than the diameter of the first floating ball 5, when the first floating ball 5 enters the first drain port 6, a flow passage is formed between the first drain port 6 and the first floating ball 5. When the drain device is working normally, the first floating ball 5 is located at the first drain port 6 and enters the first drain port 6, at this time, since the flow passage is formed between the first drain port 6 and the first floating ball 5, the first floating ball 5 will not hinder the flow of the condensed water, so that the condensed water can be smoothly drained from the first drain port 6. At the same time, since the diameter of the first drain port 6 is smaller than the diameter of the first floating ball 5, the first floating ball 5 cannot be drained from the first drain port 6 and will be stopped at the first drain port 6 by the base 1, thereby improving the reliability of the drain device when working.
[0035] In one embodiment, the first drain port 6 comprises a circular hole and an arc-shaped groove, the arc-shaped groove is arranged on the hole wall of the circular hole and recessed outward from the hole wall of the circular hole, the diameter of the circular hole is smaller than the diameter of the first floating ball 5. Since the diameter of the circular hole is smaller than the diameter of the first floating ball 5, the first floating ball 5 cannot pass through the circular hole, so that the first floating ball 5 can be stably kept in the first valve cavity 4, and the arc-shaped groove recessed outward from the hole wall of the circular hole, when the first floating ball 5 falls into the circular hole, the first floating ball 5 will not block the arc-shaped groove due to the block of the inner wall of the circular hole, so that the outside of the first floating ball 5 can form a flow passage through the arc-shaped groove, thereby ensuring that the condensed water can be smoothly drained from the arc-shaped groove.
[0036] In one embodiment, the first drain port 6 is in the shape of an ellipse, and the short side of the ellipse is smaller than the diameter of the first floating ball 5. The first floating ball 5 is spherical, so when the first drain port 6 is in the shape of an ellipse and the short side of the ellipse is smaller than the first floating ball 5, the first floating ball 5 cannot pass through the first drain port 6, and the long and short sides of the elliptical structure are not equal, which ensures that the first floating ball 5 cannot completely close the first drain port 6, so that the condensed water can flow through the overflow channel formed by the long side and the first floating ball 5.
[0037] In one embodiment, the first valve cavity 4 is in the shape of a truncated cone, which can form a smoother guide structure, facilitating the first floating ball 5 to be guided along the side wall of the first valve cavity 4 to the first valve port 3 under the action of the condensed water buoyancy and close the first valve port 3 to avoid backflow of the condensed water.
[0038] In one embodiment, the drain device further comprises a baffle 8 and a second valve seat 9, the baffle 8 is installed on the first valve seat 2, the second valve seat 9 is provided with a second valve port 10, and the second valve seat 9 and the baffle 8 form a second valve cavity 11, the cross section of the second valve cavity 11 gradually decreases along the direction close to the second valve port 10, and the second valve cavity 11 is provided with a second floating ball 12, which can float under the action of the condensed water and block the second valve port 10.
[0039] In this embodiment, a second one-way valve structure is added, which can be used in cooperation with the first one-way valve structure below. When the first one-way valve structure cannot block the backflow of the condensed water due to strong impact or long-term work, the second one-way valve structure on the upper side can continue to work to block the condensed water at the second valve port 10 on the upper side, preventing the condensed water from flowing back further, thereby improving the reliability of the drain device and reducing the number of disassembly and maintenance.
[0040] The baffle 8 limits the second floating ball 12 in the second valve cavity 11 formed by the baffle 8 and the second valve seat 9, ensuring the normal and effective work of the second floating ball 12.
[0041] In this embodiment, the baffle 8 is clamped and fixed on the upper surface of the first valve seat 2, which can realize the installation and fixation of the baffle 8 on the first valve seat 2 by using the clamping structure, which is simple in structure and convenient to operate.
[0042] The drain device further comprises a sleeve 13, the sleeve 13 is fixedly connected with the base 1, and the first valve seat 2 and the second valve seat 9 are installed in the sleeve 13. The sleeve 13 can facilitate the installation and fixation of the first valve seat 2 and the second valve seat 9, and facilitate the installation of the first floating ball 5 and the second floating ball 12, so that the structure of the drain device forms a whole, facilitating the overall installation and use. The sleeve 13 and the base 1 are connected by a buckle,
[0043] In one embodiment, the second valve seat 9 is integrally formed with the sleeve 13, and the second valve seat 9 is pressed against the baffle plate 8. In this embodiment, the second valve seat 9 is an integral structure with the sleeve 13, and thus can be integrally pressed against the baffle plate 8, thereby pressing and fixing the baffle plate 8 on the first valve seat 2, and achieving the installation and fixation of the baffle plate 8. In this case, the baffle plate 8 can be directly placed on the first valve seat 2 without being fixed on the first valve seat 2 by clamping or screwing or other connection methods, but is fixed on the first valve seat 2 by the pressing action of the second valve seat 9, and at the same time forms the fixation of the first valve seat 2.
[0044] The baffle plate 8 is provided with a second drainage port 14, and the diameter of the second drainage port 14 is smaller than the diameter of the second floating ball 12. When the second floating ball 12 enters the second drainage port 14, a flow passage is formed between the second drainage port 14 and the second floating ball 12.
[0045] In one embodiment, the second drainage port 14 includes a circular hole and an arc-shaped groove, the arc-shaped groove is arranged on the hole wall of the circular hole and is recessed radially outward from the hole wall of the circular hole, and the diameter of the circular hole is smaller than the diameter of the second floating ball 12.
[0046] In one embodiment, the cross section of the second drainage port 14 is elliptical, and the short side of the ellipse is smaller than the diameter of the second floating ball 12.
[0047] In one embodiment, the outer periphery of the second drainage port 14 is provided with a guide cylinder 15 extending towards the second valve port 10, the second floating ball 12 is located in the guide cylinder 15, and the guide cylinder 15 is provided with a flow groove 16. In this embodiment, the guide cylinder 15 can jointly act with the second valve cavity 11 to limit and guide the second floating ball 12, so that the second floating ball 12 is located near the position of the baffle plate 8 where the second drainage port 14 is arranged, and always moves along the guide of the guide cylinder 15, avoiding the second floating ball 12 from moving in other directions, and improving the reliability and stability of the movement of the second floating ball 12.
[0048] The flow groove 16 on the outer periphery of the guide cylinder 15 can ensure that when the second floating ball 12 is located in the guide cylinder 15, the condensed water can smoothly flow from the flow groove 16 to the second drainage port 14 downward, and ensure the normal drainage function of the condensed water.
[0049] In this embodiment, rectangular holes are dug in six directions of the guide cylinder 15, and six water outlets are distributed, which can limit the second floating ball 12 and do not hinder the flow of condensed water to the second drainage port 14 below the second floating ball 12, so that the condensed water can flow to the second drainage port 14 along the rectangular holes.
[0050] In one embodiment, the bottom of the sleeve 13 is provided with a stop flange 17 located on the outer circumferential side of the sleeve 13, which is clamped and fixed between the base 1. In this embodiment, by providing the stop flange 17 on the bottom of the sleeve 13, the thickness of the bottom of the sleeve 13 can be increased, so that the clamping structure can be conveniently provided on the bottom of the sleeve 13, and the clamping and fixing between the base 1 can be achieved, without affecting the structural strength of the sleeve 13, and the structural strength and stability of the cooperation between the sleeve 13 and the base 1 are improved.
[0051] In one embodiment, the side of the first valve seat 2 facing the baffle 8 is formed with a tapered surface, and the cross-sectional size of the tapered surface increases in the direction away from the first valve port 3. The tapered surface can form a larger volume cavity, and can form a condensing type temporary space, so that when the condensed water cannot be discharged in time and more condensed water enters, the second floating ball 12 can quickly block the second valve port 10, and a certain buffer space can be formed, and the condensed water treatment capacity of the drainage device is improved.
[0052] In one embodiment, the upper end of the second valve seat 9 is provided with an upwardly extending manifold 18, and the second valve port 10 is located on the inner circumferential side of the manifold 18. In this embodiment, the manifold 18 functions to collect the condensed water entering the drainage device and form a certain flow space, which can accommodate a certain amount of condensed water, so that the condensed water can be quickly collected and quickly transported to the second valve port 10. The manifold 18 can exist independently and be fixed on the second valve seat 9, or a part of the sleeve 13 can be used to form the manifold 18, for example, the part of the sleeve 13 that extends upwardly beyond the second valve seat 9 can be used as the manifold 18, thereby enhancing the integrity of the structure of the drainage device.
[0053] The sleeve 13 described above can be used as part of the pipeline, so that the drainage device is directly installed on the condensed water drainage pipeline, and the installation and fixation of the drainage device are achieved by clamping between the pipeline and the base 1, which is convenient to install, simple to disassemble and easy to maintain.
[0054] When installing the drainage device, first, the baffle 8 and the first valve seat 2 are clamped and fixed together, then the second floating ball 12 is placed at the second drainage port 14 in the middle of the baffle 8, then the baffle 8, the first valve seat 2 and the second floating ball 12 are placed as a whole into the sleeve 13 and cooperated with the second valve seat 9 in the sleeve 13. Then the first floating ball 5 is placed at the first drainage port 6 in the middle of the base 1, and the stop flange 17 on the sleeve 13 is clamped and fixed with the base 1 by buckling, at this time the first floating ball 5 is pushed into the first valve cavity 4 of the first valve seat 2, thereby achieving the installation of the entire drainage device.
[0055] When the aircraft and other equipment using the drainage device maintains a horizontal attitude, the flow direction of the condensed water flowing into the water pan is as shown in FIG. 6. Figure 3As shown, the condensed water enters the second valve port 10, then enters the guide cylinder 15 from the six flow grooves 16 on the side of the guide cylinder 15, and then is discharged from the second drainage port 14, enters the first valve port 3, flows into the first valve cavity 4 from the first valve port 3, and then flows out from the flow passage between the first float ball 5 and the first drainage port 6.
[0056] When the equipment, such as an airplane, to which the drainage device is applied is in an inclined attitude, the condensed water rises, the first float ball 5 rises under the action of the condensed water buoyancy, the first valve port 3 is closed, and if there is still a part of the condensed water flowing back to the upper side of the sleeve 13, the structure composed of the second float ball 12, the side wall of the second valve cavity 11 and the baffle 8 can prevent the condensed water from flowing back.
[0057] The drainage device in the embodiment has simple structure, small size, and can be combined and installed in multiple numbers, and on the basis of improving the anti-backflow capacity, the complexity of the overall structure is not increased.
[0058] In an embodiment, the first valve seat 2 can be provided as a cylinder having a single lower conical surface structure, and the lower conical surface is in communication with the upper surface of the cylinder through the first valve port 3.
[0059] In an embodiment, the first valve seat 2 can also be provided as an upper and lower conical surface structure, and then is welded together with the base 1 to form an integral structure, the first float ball 5 is arranged in the lower conical surface of the first valve seat 2, the first valve seat 2 is provided with threads outside, and the first valve seat 2 is fixedly connected between the threads and the sleeve 13.
[0060] The first drainage port 6 and the second drainage port 14 can be designed in any shape that does not affect the flow of the condensed water.
[0061] According to the embodiment of the present application, the water pan comprises the drainage device, which is the above-mentioned drainage device.
[0062] The water pan further comprises a base plate 19 and a water guide plate 20, the water guide plate 20 is arranged at the opening of the base plate 19, the water guide plate 20 is provided with a water guide port 7, the drainage device is arranged in the accommodating cavity formed by the water guide plate 20 and the bottom wall of the base plate 19, and is connected with the water guide port 7. The condensed water flowing out of the drainage device can enter the accommodating cavity for temporary storage, thereby improving the accommodation capacity of the water pan, and at the same time, due to the sealing effect of the water guide plate 20, the condensed water entering the accommodating cavity must pass through the drainage device to flow out when the water pan is inclined, so that the anti-backflow effect of the drainage device can be strengthened and the anti-backflow capacity of the water pan for the condensed water can be improved.
[0063] The height of the water guide plate 20 decreases along the direction close to the water guide port 7, which can increase the flow guiding effect of the water guide plate 20 and facilitate the flow guiding and collection of the condensed water.
[0064] According to the embodiments of the present application, the air conditioner comprises the water receiving tray, which is the above-mentioned water receiving tray.
[0065] Those skilled in the art can easily understand that the above-mentioned advantageous modes can be freely combined and superimposed without conflict.
[0066] The above only is the preferred embodiment of the present application, and should be pointed out, for the ordinary skilled in the art, on the premise of not departing from the technical principles of the present application, can also make a number of improvements and variations, these improvements and variations should be considered as the protection scope of the present application.
