Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to a filter element, a water tank, and an air conditioner having the same. Background Technology

[0002] Existing air conditioners are equipped with water tanks for collecting and storing condensate.

[0003] Because the condensate from the outdoor unit of an air conditioner is exposed to the outdoor environment for extended periods, including wind and rain, and because dust from the air floats on the surface of the condensate during heat exchange, the condensate inevitably contains dirt and impurities. Therefore, the condensate needs to be cleaned before it can be used for indoor humidification.

[0004] Although some existing water tanks are equipped with filtration or sedimentation devices, they are unable to effectively separate and remove large particles, floating matter, and small particulate impurities in the condensate, resulting in frequent maintenance of the subsequent drainage system and affecting the overall operational stability of the equipment. Utility Model Content

[0005] The primary objective of this invention is to provide a filter element that not only effectively intercepts floating matter but also slows down the liquid flow rate to facilitate the sedimentation of small particles.

[0006] The second objective of this invention is to provide a water tank that effectively separates and removes large particles, floating matter, and small particulate impurities from condensate water, thereby ensuring purification effectiveness.

[0007] The third objective of this invention is to provide an air conditioner that ensures effective condensate purification to reduce maintenance frequency and improve operational stability.

[0008] The first objective of this utility model is to provide a filter element including a flow guiding structure with a sloped flow guiding surface; it also includes an interception structure protruding from the flow guiding surface, the interception structure being disposed towards the higher part of the flow guiding surface.

[0009] As can be seen from the above scheme, large particles of impurities can be separated by sedimentation. The more difficult part is the separation of floating matter and small particles of impurities. After the water flows down onto the guide surface, it flows along the guide surface due to the slope design. During the flow, the raised interception structure stops the floating matter, and at the same time, the flow rate of condensate water is reduced, which is conducive to the sedimentation of smaller particles of impurities.

[0010] A further option is that the filter element includes at least two flow guiding structures arranged from top to bottom; the higher part of the flow guiding surface of one flow guiding structure receives the falling water from the lower part of the flow guiding surface of the other flow guiding structure above.

[0011] As can be seen from the above, under this setting, the condensate water passes through a multi-stage flow guiding structure to ensure the interception rate of floating objects, and the water flow speed is further reduced to ensure that the condensate water flowing through the filter element is slow and no longer carries smaller particulate impurities, thus causing the smaller particulate impurities to settle and separate.

[0012] A further approach is to create a meandering water flow path between multiple flow-guiding structures.

[0013] As can be seen from the above, this design makes full use of three-dimensional space, reduces the area occupied by the filter element, and facilitates the miniaturization of the water tank.

[0014] A further proposed solution includes a handle and a connecting arm; the handle is located above multiple flow guiding structures, and the connecting arm connects the multiple flow guiding structures and the handle.

[0015] As can be seen from the above, this design makes it easy to lift and remove the filter cartridge when it is disassembled.

[0016] Another further solution is to have an interception groove in the interception structure, with the entrance of the interception groove facing upwards.

[0017] As can be seen above, the interception groove is used to collect floating dirt. This design ensures that the intercepted dirt stays more stably on the interception structure, preventing the dirt from being washed away by the water flow for a long time and falling off the interception.

[0018] Another further approach is to arrange multiple interception structures in an array at intervals on the flow guiding surface.

[0019] As can be seen from the above, this setting further improves the interception rate and the deceleration effect on condensate.

[0020] The second objective of this utility model is to provide a water tank comprising a tank body; the tank body includes a first sedimentation zone, an interception zone, and a second sedimentation zone that are interconnected; and it also includes the aforementioned filter element, which is disposed in the interception zone.

[0021] A further proposed solution is to connect the first sedimentation zone, the interception zone, and the second sedimentation zone sequentially; the uppermost part of the guide surface of the interception zone collects the overflow water from the first sedimentation zone; and the second sedimentation zone collects the falling water from the lowermost part of the guide surface of the interception zone.

[0022] As can be seen from the above scheme, larger particles are not easily affected by water flow and are effectively separated after settling in the first sedimentation zone. After the water flows onto the guide surface of the filter element's guide structure, it flows along the guide surface due to its slope design. During the flow, the raised interception structure stops floating objects, and the reduced flow velocity of the condensate water facilitates the sedimentation of smaller particles. The slower-flowing water drips into the second sedimentation zone, where smaller particles are effectively separated and settled. Therefore, the water tank of this invention effectively separates and removes large particles, floating objects, and small particles from condensate water, solving the technical problems of low removal efficiency, incomplete purification, and easy clogging of the drainage system. Since the water flow velocity slows down slightly after the first sedimentation, either interception followed by two sedimentation cycles, or two sedimentation cycles followed by interception, can also achieve the separation of large particles, floating objects, and small particles. However, the sequential arrangement of the first sedimentation zone, interception zone, and second sedimentation zone is a more optimal filtration order.

[0023] A further proposed solution is to install a magnetic suction device at the bottom of the first sedimentation zone.

[0024] As can be seen above, the magnetic adsorption device is used to adsorb metal particle impurities in condensate water, further improving the cleaning effect.

[0025] A further proposed solution is to provide a first drain outlet and a first sealing structure to block the first drain outlet at the bottom of the first sedimentation zone; and / or, to provide a second drain outlet and a second sealing structure to block the second drain outlet at the bottom of the second sedimentation zone.

[0026] As can be seen from the above, removing the first sealing structure can flush and clean the first sedimentation area, and / or removing the second sealing structure can flush and clean the second sedimentation area, washing away the dirt accumulated at the bottom of the sedimentation area.

[0027] A further solution is to connect the magnetic device to the first sealing structure, and the two can be detached together.

[0028] As can be seen from the above, under this setup, the magnetic suction device can be removed at the same time as the first sealing structure is removed, which makes it easier to clean the magnetic suction device.

[0029] Another further design is that the box body includes a first partition, and the first sedimentation zone includes a first part and a second part located on both sides of the first partition. The first part is connected to the inlet of the first sedimentation zone, and the second part is connected to the overflow outlet of the first sedimentation zone. A connection is formed between the bottom of the first partition and the magnetic suction device, and the first part and the second part are connected only by the connection.

[0030] As can be seen from the above, under this setting, the condensate in the first sedimentation zone must pass through a connection port that is close enough to the magnetic attraction device to ensure that the metal particle impurities in the condensate are adsorbed by the magnetic attraction device.

[0031] Another further option is that the tank body includes a water-blocking structure with a sloped water-blocking surface; the water-blocking structure is located above the first sedimentation zone and the water-blocking surface is located directly below the inlet of the first sedimentation zone, and the lower part of the water-blocking structure forms a drain outlet between the tank body and the plate.

[0032] As can be seen above, if condensate drips directly onto the bottom of the first sedimentation zone, it will produce a loud water flow sound, affecting the user experience. However, with the water-blocking structure installed, the condensate can be blocked and guided to slide down the side wall of the water tank, reducing the impact of the water flow and lowering the water flow sound.

[0033] Another further option is that the tank also includes a purified water storage area, which is connected to the tank's outlet; the purified water storage area holds the overflow water from the second sedimentation zone.

[0034] A further proposed solution is that the water tank includes a water level detection device and a water pump. The water level detection device detects the water level in the purified water storage area, and the water pump is located at the water outlet. The water pump operates based on the detection signal from the water level detection device.

[0035] As can be seen from the above, under this setting, when the water level in the purified water storage area is detected by the water level detection device to exceed the preset water level, the water pump will be automatically started to pump water for indoor atomization.

[0036] Another further option is that the water tank includes a cover, the top of which has a disassembly port, and the cover can be detachably fitted onto the disassembly port; the filter element is installed and removed through the disassembly port.

[0037] As can be seen above, this design facilitates the removal of the filter cartridge.

[0038] The air conditioner provided by the third objective of this utility model includes the aforementioned water tank. Attached Figure Description

[0051] Example of filter element, water tank and air conditioner

[0052] See Figure 1 The air conditioner of this invention includes a condensate filtration system for recovering and filtering condensate water and atomizing the filtered condensate water for indoor humidification. The condensate filtration system includes a first water pump 91, a first pipe 92, a water tank 1, a second pipe 94, and an atomizing device 95. The first water pump 91 pumps condensate water from the drip tray. The first pipe 92 connects the outlet of the first water pump 91 to the inlet 111 of the water tank 1. A second water pump 93 is installed at the outlet 112 of the water tank 1. The second water pump 93 is the pump of this invention, pumping the filtered water from the water tank 1 and transporting it through the second pipe 94 to the atomizing device 95 for atomization. The air conditioner includes an outdoor unit and an indoor unit; preferably, the water tank 1 is located in the indoor unit.

[0053] See Figure 2 The water tank 1 includes a tank body 11, a cover 12, a first sealing structure 13, a second sealing structure 14, a filter element 2, a magnetic attraction device 81, a float 82, a Hall sensor 83, and a second water pump 93. The float 82 and the Hall sensor 83 constitute the water level detection device of this utility model.

[0054] See Figure 2 and Figure 3The housing 11 includes an inlet 111, a first sedimentation zone 101, an interception zone 102, a second sedimentation zone 103, a purified water storage zone 104, and an outlet 112, which are connected in sequence. The first sedimentation zone 101 is used to settle and separate large particulate impurities and metal impurities in the condensate; the filter element 2 is installed in the interception zone 102 to intercept floating objects in the condensate; the second sedimentation zone 103 is used for secondary sedimentation to separate small particulate impurities in the condensate; and the purified water storage zone 104 is used to store the filtered purified water.

[0055] The box 11 includes a vertically arranged second partition 117, and the internal space of the box 11 is divided into a left space and a right space by the second partition 117.

[0056] The first sedimentation zone 101 is located in the left space. Further, the box body 11 includes a plate 115, which is the outer wall of the box body 11. The first sedimentation zone 101 is located between the plate 115 and the second partition 117. The top of the second partition 117 and the top wall of the box body 11 form the overflow outlet 101e of the first sedimentation zone 101.

[0057] Interception zone 102, second sedimentation zone 103 and purified water storage zone 104 are all located in the right space, and interception zone 102 is located above the second sedimentation zone 103 and purified water storage zone 104.

[0058] The housing 11 also includes a third partition 119. The second sedimentation zone 103 and the purified water storage zone 104 are arranged horizontally and adjacent to each other. The third partition 119 is located between the second sedimentation zone 103 and the purified water storage zone 104, and an overflow outlet for the second sedimentation zone 103 is formed above the third partition 119. In addition, the water inlet of the first sedimentation zone 101 is the water inlet 111 of the housing 1.

[0059] Combined Figure 4 The condensate entering from the inlet 111 drips into the first sedimentation zone 101. The filter element 2 in the interception zone 102 collects the overflow water from the overflow outlet 101e of the first sedimentation zone 101. The second sedimentation zone 103 collects the water falling from the interception zone 102. The purified water storage zone 104 collects the overflow water from the overflow outlet 103a of the second sedimentation zone 103.

[0060] See Figure 2 and Figure 3 The bottom of the first sedimentation zone 101 is provided with a first drain outlet 113 and a first sealing structure 13 to block the first drain outlet 113, and the bottom of the second sedimentation zone 103 is provided with a second drain outlet 114 and a second sealing structure 14 to block the second drain outlet 114. In this embodiment, both the first sealing structure 13 and the second sealing structure 14 are rubber plugs.

[0061] Combination Figure 7Removing the first sealing structure 13 allows for rinsing and cleaning of the first sedimentation zone 101, and removing the second sealing structure 14 allows for rinsing and cleaning of the second sedimentation zone 103, thus removing the accumulated dirt at the bottom of the sedimentation zone. When cleaning the first sedimentation zone 101, water can be flushed from the inlet 111 to the first drain 113, or vice versa; both methods are acceptable. Additionally, a downward-extending connection pipe is installed at the bottom of the housing 11 at the first drain 113. When the user is not using the atomizing emission function, a drain pipe can be connected to this connection pipe, allowing condensate to enter the first sedimentation zone 101 and be directly discharged through the first drain 113.

[0062] Furthermore, a magnetic adsorption device 81 is installed at the bottom of the first sedimentation zone 101. The magnetic adsorption device 81 is used to adsorb metal particulate impurities in the condensate, further improving the cleaning effect. Even further, compared to... Figure 2 and Figure 3 The outer circumference of the magnetic suction device 81 is smaller than the inner circumference of the first drain outlet 113. The magnetic suction device 81 is fixedly connected to the first sealing structure 13, and the two can be disassembled together. With this configuration, the magnetic suction device 81 can be removed at the same time as the first sealing structure 13 is removed, which facilitates the cleaning of the magnetic suction device 81.

[0063] A further embodiment is that the housing 11 includes a first partition 116, which is a flat plate extending downward from the top wall of the housing 11 in the horizontal direction. Figure 2 and Figure 3 (As shown in the left-right direction), the first sedimentation zone 101 includes a first part 101a and a second part 101b located on both sides of the first partition 116. The first part 101a is connected to the inlet 111, and the second part 101b is connected to the overflow outlet 101e.

[0064] like Figure 2 As shown, in this configuration, a communication port 101c is formed between the bottom of the first partition 116 and the magnetic attraction device 81, and the first part 101a and the second part 101b are connected only by the communication port 101c. With this configuration, the condensate in the first sedimentation zone 101 will necessarily pass through the communication port 101c, which is sufficiently close to the magnetic attraction device 81, ensuring that metal particle impurities in the condensate are adsorbed by the magnetic attraction device 81.

[0065] See also Figure 2 and Figure 3 Furthermore, the housing 11 includes a water-blocking structure 118, which is an inclined plate. The water-blocking structure 118 extends obliquely downward from the left side surface of the first partition 116 and is located on the upper part of the first section 101a.

[0066] The water-blocking structure 118 has a sloped water-blocking surface 1181. The water-blocking structure 118 is located above the first sedimentation zone 101, with the water-blocking surface 1181 directly below the water inlet 111. A drain outlet 101d is formed between the lower part 1182 of the water-blocking structure 118 and the plate 115 of the housing 11. Preferably, the first inclination angle α of the water-blocking surface 1181 relative to the horizontal plane ranges from 10 degrees to 20 degrees; preferably, the width d1 of the drain outlet 101d is 10 millimeters. With this configuration, the water-blocking structure 118 blocks and guides condensate water to slide off the plate 115, reducing water flow impact and noise.

[0067] See Figures 5 to 7 The top of the housing 11 is provided with a disassembly port 120, and the cover 12 is detachably closed on the disassembly port 120; the filter element 2 is disassembled and installed through the disassembly port 120. In addition, after removing the filter element 2, water can be injected from the disassembly port 120 or the second drain port 114 to flush the interception zone 102, the second sedimentation zone 103 and the purified water storage zone 104.

[0068] See Figure 8 and Figure 9 The filter element 2 includes a flow guiding structure 21, an interception structure 22, a handle 23, and a connecting arm 24. The flow guiding structure 21 is a flat plate with an inclined arrangement.

[0069] The upper surface of the flow guiding structure 21 is a sloped flow guiding surface 210, which includes a high portion 2101 and a low portion 2102 arranged opposite to each other along its downward slope direction. The flow guiding surface 210 is in the same direction of inclination as the flow guiding structure 21 to which it is located. See also Figure 9 In this embodiment, the second tilt angle b of the guide surface 210 relative to the horizontal plane ranges from 20 degrees to 30 degrees.

[0070] The intercepting structure 22 protrudes from the guide surface 210 and is positioned towards the high portion 2101 of the guide surface 210. In this embodiment, multiple intercepting structures 22 are arranged in an array at intervals on the guide surface 210. Furthermore, the multiple intercepting structures 22 comprise multiple rows arranged sequentially along the downslope direction of the guide surface 210, with any two adjacent rows of intercepting structures 22 staggered. The staggered arrangement of any two adjacent rows of intercepting structures 22 in the downslope direction means that a gap is formed between each row of two adjacent intercepting structures 22, which serves as a waterway, and the gaps between adjacent rows of intercepting structures 22 are staggered. This arrangement simultaneously ensures the interception effect of floating objects, maintains water flow, and reduces flow velocity.

[0071] Furthermore, in this embodiment, the interception structure 22 is provided with an interception plane facing the high portion 2101, and the interception plane is provided with an interception groove 220, that is, the entrance of the interception groove 220 is provided facing the high portion 2101. In addition, the interception structure 22 also includes an arcuate contour surface facing away from the high portion 2101. Here, the interception structure 22 being provided facing the high portion 2101 of the guide surface 210 means that the working part of the interception structure 22 is provided facing the high portion 2101. In this embodiment, the working part of the interception structure 22 is the interception plane and the interception groove 220 of the interception plane.

[0072] In this embodiment, there are four flow guiding structures 21 arranged from top to bottom. The tilting directions of any two adjacent flow guiding structures 21 are opposite. For example, if the topmost flow guiding structure 21 tilts downward from left to right, then the second flow guiding structure 21 tilts downward from right to left.

[0073] Combination Figure 10 The higher portion 2101 of the guide surface 210 of one guide structure 21 receives the falling water from the lower portion 2102 of the guide surface 210 of another guide structure 21 above it. This arrangement creates a meandering water flow path between the multiple guide structures 21.

[0074] Furthermore, in order to ensure the water-receiving effect, the high part 2101 of the guiding surface 210 of one guiding structure 21 should extend outward in the horizontal direction by a certain distance d2 relative to the low part 2102 of the guiding surface 210 of the other guiding structure 21 above it. Preferably, the distance d2 is 10 mm.

[0075] Additionally, the handle 23 is located above the multiple flow guiding structures 21, and the vertically extending connecting arms 24 connect the multiple flow guiding structures 21 and the handle 23, with the two connecting arms 24 positioned on both sides of the width of the multiple flow guiding structures 21. The handle 23 and the connecting arms 24 achieve relative fixation of the multiple flow guiding structures 21 and make the filter element 2 easy to remove.

[0076] See Figure 10 The uppermost part 2101 of the guide surface 210 of the interception zone 102 receives the overflow water from the overflow outlet 101e of the first sedimentation zone 101, while the second sedimentation zone 103 receives the falling water from the lower part 2102 of the guide surface 210 of the interception zone 102.

[0077] See Figure 11 and Figure 12The purified water storage area 104 receives and stores the overflow water from the second sedimentation area 103. The float 82 rises as the water level in the purified water storage area 104 rises. When the float 82 reaches the preset water level, the sensor on the float 82 is detected by the Hall sensor 83. At this time, the water level detection device detects that the water level in the purified water storage area 104 exceeds the preset water level, and the second water pump 93 is automatically started to pump water for indoor atomization.

[0078] Mainly, larger particles are less affected by water flow and are effectively separated after settling in the first sedimentation zone 101. Water flows onto the guide surface 210 of the guide structure 21 of the filter element 2, and flows along the guide surface 210 due to its slope design. During this flow, the raised interception structure 22 stops floating objects, and the reduced flow rate of the condensate water facilitates the sedimentation of smaller particles. The slower-flowing water drips into the second sedimentation zone 103, where smaller particles are effectively separated and settled. Therefore, this utility model's water tank effectively separates and removes large particles, floating objects, and small particles of impurities from condensate water without the need for a filter screen, solving the technical problems of low removal efficiency, incomplete purification, and easy clogging of the drainage system.

[0079] In other embodiments, the first partition may not be provided.

[0080] In other embodiments, the magnetic attraction device may not be provided.

[0081] In other embodiments, multiple interception structures on the same flow guiding structure can be configured in two or more different forms. For example, some interception structures can be configured as sawtooth-shaped, some interception structures can be configured as wave-shaped, and other interception structures can be configured as in the form of the first embodiment.

[0082] In other embodiments, the second sedimentation zone is configured as a removable box portion of the casing.

[0083] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
