[0057] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0058] Below, refer to Figures 1 - 12 Describe a water treatment device 100 according to an embodiment of the first aspect of the present utility model. The water treatment device 100 of this embodiment is used for an air conditioner. The air conditioner of this embodiment can be a kitchen air conditioner 1000. Referring to FIGS. 1 and Figure 2 , the air conditioner includes an indoor component 300 and an outdoor component 400. The indoor component 300 includes a water receiving tray for receiving the condensed water dripping from the evaporator 310 of the indoor component 300. The outdoor component 400 is formed with a water storage tank in which water can be stored for use by the water consumption module of the outdoor component 400. For example, the water consumption module can be a water pumping device 440. The water pumping device 440 is configured to pump the water in the water storage tank onto the condenser 410 of the outdoor component 400 for cooling the condenser 410.

[0059] The water treatment device 100 is used to treat the condensed water generated by the indoor component 300, such as filtering, oil absorption, sterilization, and / or acid removal, etc., and then send the treated water to the outdoor component 400 for consumption by the outdoor component 400. For example, it is sent into the water storage tank of the outdoor component 400 for the water pumping device 440 to pump water to cool the condenser 410 of the outdoor component 400.

[0060] As Figures 4 - 6As shown, the water treatment device 100 according to the embodiment of the first aspect of the present utility model includes: a housing 10, a plurality of filtering structures 20, and a water pump.

[0061] Specifically, the housing 10 defines a receiving cavity 101, and an inlet 102 and a drain outlet 103 communicating with the receiving cavity 101 are formed on the housing 10; the inlet 102 is adapted to communicate with a water receiving tray, and the drain outlet 103 is adapted to communicate with a water storage tank. A plurality of filtering structures 20 are all disposed in the receiving cavity 101. The filtering structure 20 includes a box body 21 and a filtering element 22. A filtering cavity 2101 is defined in the box body 21, and an inlet 2102 and an outlet 2103 communicating with the filtering cavity 2101 are formed on the box body 21. The filtering element 22 is disposed in the filtering cavity 2101. The filtering cavities 2101 of the plurality of filtering structures 20 are sequentially connected to form a filtering channel of the water treatment device 100, and both ends of the filtering channel communicate with the inlet 102 and the drain outlet 103 respectively; the water pump is connected to the inlet 102 for driving water to flow from the inlet 102 to the drain outlet 103.

[0062] Wherein, the number of the filtering structures 20 can be two, three, four, five, six or more, and the user can set the number and type of the filtering structures 20 according to actual filtering requirements.

[0063] The filtering structure 20 is an integral part. The box body 21 of the filtering structure 20 can provide a layout space for the filtering element 22, which is convenient for arranging the filtering element 22, and at the same time plays a role in limiting and fixing the filtering element 22 to prevent the filtering element 22 from leaking into the receiving cavity 101. The filtering element 22 can be used to purify water quality. For example, the filtering element 22 can filter impurities in water, sterilize the water entering the filtering cavity 2101, filter metal ions in water, remove grease in water, and / or remove acidic substances in water, etc.

[0064] The plurality of filtering structures 20 can be arranged sequentially. For example, the plurality of filtering structures 20 can be arranged in sequence along the up and down direction. In this way, the thickness of the water treatment device 100 can be reduced, and the space occupation can be reduced. The plurality of filtering structures 20 are sequentially connected to form a filtering channel. In this way, the water flowing in from the inlet can be filtered through the plurality of filtering structures 20 in sequence to achieve multi-stage filtering, so as to improve the water treatment effect. Among them, the functions of the plurality of filtering structures 20 can be the same or different.

[0065] Among the plurality of filtering brick structures, only one filtering element 22 of the filtering structure 20 can be an oil-absorbing element 22a, or two, three, four or more filtering elements 22 of the filtering structure 20 can be oil-absorbing elements 22a. The oil-absorbing element 22a can be an oil-absorbing felt or other materials that can adsorb grease. The oil-absorbing element 22a can adsorb grease in the condensed water in the filtering cavity 2101 and play a role in deoiling and purifying the condensed water.

[0066] The water pump can provide driving force for the condensate water, and is used to pump the condensate water collected in the indoor component 300 to the water treatment device 100. Specifically, when the height of the condensate water in the water receiving tray of the indoor component 300 reaches a preset height, the water pump can be started. The water pump transports the water in the water receiving tray to the water inlet 102 of the water treatment device 100, and then enters the filtration chamber 2101 through the inlet 2102 on the box body 21 of the first filtration structure 20. In the filtration chamber 2101, the filter element 22 filters and purifies the condensate water. The purified condensate water is discharged from the outlet 2103, and enters the next filtration chamber 2101 through the inlet 2102 on the box body 21 of the next filtration structure 20, and filters and / or purifies the condensate water again until it flows out from the outlet 2103 of the last filtration structure 20. Finally, the condensate water is discharged from the drain outlet 103 of the housing 10. The condensate water discharged from the drain outlet 103 can flow into the water storage tank of the outdoor component 400, and is used for the water pumping device 440 to pump water. The water pumping device 440 sends the water to the surface of the condenser 410 to realize heat dissipation and cooling of the condenser 410.

[0067] In this embodiment, the water treatment device 100 can transport the condensate water generated by the outdoor component 400 to the water storage tank of the outdoor component 400 for consumption by the water consumption module of the outdoor component 400. In this way, the condensate water does not need to be discharged externally. Therefore, it is possible to avoid disturbing the people upstairs, downstairs and downstairs.

[0068] In this embodiment, the water treatment device 100 is applied to the kitchen air conditioner 1000. The filter element 22 in the filtration structure 20 can filter and purify the condensate water, improve the purity of the condensate water, reduce the probability of pollution and corrosion of the outdoor component 400 of the kitchen air conditioner 1000, improve the stability of the operation of the kitchen air conditioner 1000, and extend the service life of the kitchen air conditioner 1000.

[0069] According to the water treatment device 100 of the embodiment of the present invention, by arranging a plurality of filtration structures 20, the plurality of filtration structures 20 can cooperate with each other to filter and purify the impurities in the condensate water. In this way, the purity of the condensate water can be improved, the probability of pollution and corrosion of the outdoor component 400 can be reduced, the stability of the operation of the air conditioner can be improved, and the service life of the air conditioner can be extended. In addition, the water treatment device 100 of this embodiment can transport the condensate water generated indoors to the outdoor component 400 after purification treatment, without discharging the condensate water generated by the indoor component 300 externally, and avoiding disturbing pedestrians due to the external discharge of condensate water.

[0070] In some embodiments of the present invention, such as Figure 6As shown, the box body 21 is provided with an inlet grille 214, and the inlet grille 214 covers the inlet 2102; and / or, the box body 21 is provided with an outlet grille 215, and the outlet grille 215 covers the outlet 2103.

[0071] The inlet grille 214 is a grid-shaped plate body. The inlet grille 214 can be integrally formed with the box body 21 or installed as an independent component at the position of the inlet 2102. A plurality of grille holes are formed on the inlet grille 214. When water enters the box body 21 through the inlet grille 214 from the inlet 2102, the condensed water can enter the box body 21 through the grille holes on the inlet grille 214, so that the filter element 22 can further purify the condensed water. The inlet grille 214 can block substances with relatively large sizes in the condensed water entering from the water inlet 102, prevent impurities with larger particles from blocking the filtering structure 20, and extend the service life of the filtering structure 20. In addition, the inlet grille 214 can also play a role in diverting the water flow at the inlet 2102, reducing the flow rate and reducing the impact on the filter element 22.

[0072] The outlet grille 215 is a grid-shaped plate body. The outlet grille 215 can be integrally formed with the box body 21 or installed as an independent component at the position of the outlet 2103. A plurality of grille holes are formed on the outlet grille 215. When the condensed water flows out of the box body 21 through the outlet grille 215, the outlet grille 215 can block substances with relatively large sizes in the condensed water flowing out of the outlet 2103. For example, it can block the filter element 22 from flowing out of the filtering cavity 2101, reducing the loss of the filter element 22. The outlet grille 215 can also slow down the flow rate of the outlet water, play a role in hindering the fluid downstream of the outlet grille 215, and prevent backflow.

[0073] In some embodiments of the present invention, as Figure 6 shown, an avoidance cavity 2104 is further defined in the box body 21. The avoidance cavity 2104 is opposite to the inlet 2102, and the filtering cavity 2101 is communicated with the inlet 2102 through the avoidance cavity 2104.

[0074] When the condensed water enters the box body 21 from the inlet 2102, it can first flow into the avoidance cavity 2104 and then enter the filtering cavity 2101 through the avoidance cavity 2104. In this way, on the one hand, the avoidance cavity 2104 can play a role in buffering and temporarily storing the condensed water entering from the inlet 2102, making the condensed water evenly enter the filtering cavity 2101. On the other hand, it can avoid the condensed water entering from the inlet 2102 directly impacting the filter element 22 in the filtering cavity 2101, reducing the impact force on the filter element 22 and improving the service life of the filter element 22.

[0075] In a specific embodiment of the present invention, as Figure 6As shown, the box body 21 also includes: a baffle 216, which is arranged in the air-avoiding cavity 2104 and faces the inlet 2102, and the periphery of the baffle 216 is sealedly connected to the peripheral wall of the air-avoiding cavity 2104, and a plurality of water holes 2161 are formed on the baffle 216 and pass through the baffle 216 along the thickness direction.

[0076] The baffle 216 is arranged in the air-avoiding cavity 2104 and is sealed with the peripheral wall of the air-avoiding cavity 2104. That is, the baffle 216 divides the air-avoiding cavity 2104 into two chambers: a first chamber and a second chamber. The first chamber is located on the side of the baffle 216 facing the inlet 2102, and the second chamber is located on the side of the baffle 216 away from the inlet 2102. The condensed water entering from the inlet 2102 can first enter the first chamber, and then pass through the multiple water holes 2161 on the baffle 216 to enter the second chamber, and then enter the filter chamber 2101 through the second chamber.

[0077] In this way, the baffle 216 can separate the inlet 2102 from the filter cavity 2101, and can buffer the condensed water entering the inlet 2102, further reducing the impact force on the filter element 22 in the filter cavity 2101. At the same time, the baffle 216 can redistribute the condensed water entering the inlet 2102, so that the condensed water can enter the filter cavity 2101 more evenly, thereby improving the filtration efficiency of the filter element 22. In addition, the baffle 216 can also block and filter larger particulate matter in the condensed water entering the inlet 2102, thereby improving the filtration effect of the filter structure 20.

[0078] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, the box body 21 includes: a main box 211 and a box cover 212. The top of the main box 211 is open, and the box cover 212 covers the open side of the top of the main box 211 and is detachably connected to the main box 211.

[0079] The box body 21 can be in the shape of a rectangular parallelepiped. Specifically, the main box 211 extends in the left-right direction and defines a cavity with an open top. The box cover 212 is disposed on the top of the main box 211 and covers the top opening of the cavity. The main box 211 and the box cover 212 cooperate to enclose a filter cavity 2101 and a cavity 2104. The main box 211 and the box cover 212 can be sealed. For example, a sealing ring can be provided between the main box 211 and the box cover 212. The sealing ring extends in an annular shape along the top opening of the main box 211 and abuts between the main box 211 and the box cover 212.

[0080] Among them, the lid 212 and the main box 211 can be connected by fasteners or by snap connection. In this embodiment, the main box 211 and the lid 212 are detachably connected, which can facilitate the installation, disassembly and replacement of the filter element 22 in the box body 21, improve the installation and disassembly efficiency, enhance the convenience of maintenance, and reduce the maintenance cost of the water treatment device.

[0081] In some specific embodiments of the present utility model, such as Figure 6 shown, the box body 21 further includes: at least one partition 213, the partition 213 is arranged in the main box 211 and divides the filter cavity 2101 into a plurality of sub-cavities 21011, and the plurality of sub-cavities 21011 are sequentially connected between the inlet 2102 and the outlet 2103, and a filter element 22 is provided in each sub-cavity 21011.

[0082] For example, the number of partitions 213 can be one, two, three, four, five or more, etc., and the partitions 213 are arranged between the inlet 2102 and the outlet 2103. For example, the box body 21 extends in the left-right direction, the inlet 2102 and the outlet 2103 are respectively formed at the left and right ends of the box body 21, and the plurality of partitions 213 are arranged perpendicular to the left-right direction, and the plurality of partitions 213 can be arranged at intervals in the left-right direction in sequence.

[0083] Among them, only one filter element 22 can be arranged in any one of the sub-cavities 21011, and multiple filter elements 22 can also be arranged in any one of the sub-cavities 21011.

[0084] In this embodiment, by providing the partition 213 and using the partition 213 to divide the filter cavity 2101 into a plurality of sub-cavities 21011, the effect of multi-stage filtration can be achieved in a single filter structure 20, thereby improving the overall filtration effect of the water treatment device 100. And the same or different filter elements 22 can be arranged in each sub-cavity 21011, which can perform multi-level filtration on the same impurities or filter different impurities separately, improve the filtration effect on the condensed water, and improve the purity of the condensed water. In addition, the partition 213 is arranged in the box body 21, and the partition 213 can increase the structural strength of the box body 21, improve the overall structural strength of the water treatment device 100, and extend the service life.

[0085] Furthermore, a communication hole penetrating the partition 213 in the thickness direction of the partition 213 is formed on the partition 213, and / or, the partition 213 is spaced apart from the lower surface of the lid 212.

[0086] In one example, the perimeter of the partition plate 213 is sealingly connected to the inner wall of the filtering cavity 2101. One or more communication holes are provided on the partition plate 213, and the communication holes communicate the spaces on both sides in the thickness direction of the partition plate 213. In another example, the partition plate 213 is connected to the two opposite side walls and the bottom wall of the filtering cavity 2101, and the upper edge of the partition plate 213 is spaced apart from the top surface of the filtering cavity 2101 to form a communication port communicating between the two sub-cavities 21011. In yet another example, the perimeter of the partition plate 213 is connected to the inner wall of the filtering cavity 2101, one or more communication holes are formed on the partition plate 213, and the upper edge of the partition plate 213 is spaced apart from the top wall of the filtering cavity 2101 to form a communication port.

[0087] One or more communication holes may be provided on the partition plate 213. When multiple communication holes are provided on the partition plate 213, the multiple communication holes may be arranged at intervals. This can increase the flow area, reduce the flow resistance of the condensed water, and improve the filtering efficiency.

[0088] When the condensed water enters the filtering cavity 2101 from the condensate avoidance cavity 2104, it can first enter the first sub-cavity 21011, and the filter element 22 in the first sub-cavity 21011 is used for filtering. After the filtering is completed in the first sub-cavity 21011, the condensed water enters the next sub-cavity 21011 through the communication holes on the partition plate 213, or can also enter the next sub-cavity 21011 through the gap between the partition plate 213 and the box cover 212, and further filtering is performed in the next sub-cavity 21011.

[0089] In this embodiment, by providing communication holes on the partition plate 213 and spacing the partition plate 213 apart from the top wall of the filtering cavity 2101 to form a communication port communicating between the two sub-cavities 21011, it is convenient to communicate adjacent sub-cavities 21011, simplify the structure of the box body 21, and facilitate processing and manufacturing.

[0090] In a specific example of the present utility model, in the same filtering structure 20, the filter elements 22 in multiple sub-cavities 21011 are the same or different, and the filter element 22 in any one of the sub-cavities 21011 is an antibacterial agent, alumina 22b, activated carbon or oil-absorbing felt.

[0091] When different filter elements 22 are provided in each sub-cavity 21011, not only can multi-stage filtering be realized in the same filtering structure 20, but also different impurities can be filtered in each stage of filtering, improving the overall filtering effect of the filtering structure 20. When the same type of filter element 22 is provided in multiple sub-cavities 21011 in the same filtering structure 20, the filtering effect on one type of impurity can be improved, and the purity of the condensed water can be increased.

[0092] Among them, the bacteriostatic agent can effectively inhibit the growth of bacteria in the condensate water and reduce the probability of the condensate water deteriorating and mildewing. Alumina 22b can remove heavy metal ions and some organic matters in the condensate water, improving the purity of the condensate water. The activated carbon has strong adsorption ability and can remove impurities such as peculiar smell, color and organic matters in the condensate water. The oil-absorbing felt is used to adsorb the oil components in the water and remove the oil pollutants in the condensate water.

[0093] In a specific example of the present utility model, as Figure 6 shown, each filtering structure 20 is formed with three sub-cavities 21011. The multiple filtering structures 20 include a first filtering structure 20a, a second filtering structure 20b, a third filtering structure 20c and a fourth filtering structure 20d arranged in sequence. Among them, along the water flow direction, the filtering elements 22 in the three sub-cavities 21011 of the first filtering structure 20a are in sequence: a bacteriostatic agent, alumina 22b and alumina 22b. The filtering elements 22 in the three sub-cavities 21011 of the second filtering structure 20b are all oil-absorbing felts. The filtering elements 22 in the multiple sub-cavities 21011 of the third filtering structure 20c and the fourth filtering structure 20d are alumina 22b and activated carbon, and the alumina 22b and the activated carbon are alternately arranged along the water flow direction.

[0094] When the condensate water enters the first filtering structure 20a from the water inlet 102, the first filtering structure 20a can first remove the bacteria in the water through the bacteriostatic agent, and then remove the heavy metal ions and some organic matters in the water through the alumina 22b. In the second filtering structure 20b, the oil in the condensate water can be filtered and adsorbed at three levels, improving the removal effect of the oil in the condensate water. In the third filtering structure 20c and the fourth filtering structure 20d, the alternately arranged alumina 22b and activated carbon further remove the heavy metal ions, organic matters, peculiar smell and color in the condensate water, improving the purity of the condensate water.

[0095] In this embodiment, by setting four filtering structures 20 and each filtering structure 20 is provided with three sub-cavities 21011, twelve-level filtration of the condensate water can be realized, and different filtering elements are set for different impurities, which can improve the overall filtering effect of the water treatment device 100. In addition, by setting different filtering elements 22 in different filtering structures 20, the filtering efficiency can be improved, and the stability and durability of the water treatment device 100 can be enhanced.

[0096] In some specific embodiments of the present utility model, as Figure 6 shown, the box cover 212 is formed with a recessed portion 2121. The recessed portion 2121 is formed by a part of the box cover 212 recessing towards the main box 211, and the inlet 2102 is formed in the recessed portion 2121.

[0097] The recessed portion 2121 can form a groove on the upper side of the lid 212, and the inlet 2102 is formed on the bottom wall of the groove. In this way, the recessed portion 2121 can play a role in converging and guiding the condensed water entering from the water inlet 102, ensuring that the condensed water can enter the box body 21 through the inlet 2102 and preventing the condensed water entering from the water inlet 102 from flowing to other positions. In addition, the recessed portion 2121 can also increase the structural strength of the lid 212, improve the structural strength of the box body 21, and enhance the reliability and stability of the water treatment device 100. In addition, compared with setting a protruding water inlet 102, setting the inlet 2102 in the recessed portion 2121 can reduce the occupied space of the box body 21 and make the structure more compact.

[0098] In some specific examples of the present utility model, such as Figure 6 As shown, a guiding rib 217 is provided on the lower side surface of the main box 211. The guiding rib 217 extends circumferentially along the outlet 2103 to form a ring shape, and the guiding rib 217 is adapted to extend into the recessed portion 2121 of the filtering structure 20 located below the guiding rib 217.

[0099] Wherein, in a cross-section perpendicular to the flow direction of the outlet 2103, the cross-sectional shape of the guiding rib 217 can be a circular ring shape or a rectangular ring shape.

[0100] In this embodiment, the guiding rib 217 can play a guiding role in the condensed water flowing out from the outlet 2103, so that the condensed water can smoothly flow into the groove defined by the lower recessed portion 2121 and enter the box body 21 of the filtering structure 20 through the inlet 2102 located in the recessed portion 2121. In addition, by providing the guiding rib 217 at the position of the outlet 2103, the structural strength of the box body 21 at the position of the outlet 2103 can be improved, and the reliability and stability of the box body 21 at the position of the outlet 2103 can be enhanced. In addition, the guiding rib 217 is cooperated with the recessed portion 2121, and the positioning and cooperation of the two filtering structures 20 can also be realized, improving the assembly efficiency between the two filtering structures 20.

[0101] In some embodiments of the present utility model, such as Figure 6 As shown, the housing 10 includes a housing body 11 and a top cover 12. The top of the housing body 11 is open, the top cover 12 is sealed inside the housing body 11, the water inlet 102 is formed on the top cover 12, and the drain outlet 103 is formed on the bottom of the housing body 11.

[0102] }Wherein, the top cover 12 and the housing body 11 can be detachably connected. For example, the top cover 12 and the housing body 11 can be snap-connected or connected by fasteners. In this way, it is convenient to assemble the filtering structure 20 into the housing 10, and it is also convenient for the installation, disassembly, maintenance and replacement of the filtering structure 20.

[0103] The water inlet 102 is formed on the top cover 12. For example, the water inlet 102 can be formed on the top of the top cover 12 and penetrate through the top surface of the top cover 12 in the up and down direction. The water inlet 102 can also be formed on the side wall of the top cover 12 and penetrate through the top cover 12 in the thickness direction of the side wall of the top cover 12. Setting the water inlet 102 on the top cover 12 can facilitate the smooth entry of condensed water into the water treatment device 100 and reduce the water inlet resistance.

[0104] The drain port 103 is formed at the bottom of the housing 11. For example, the drain port 103 penetrates through the bottom wall of the housing 11 in the up and down direction. The drain port 103 can also be arranged on the side wall at the bottom of the housing 11, close to the bottom wall of the housing 11. In this way, it can facilitate the discharge of the condensed water in the housing 11 and also facilitate the complete discharge of the condensed water in the housing 11, improving the drainage efficiency.

[0105] In one example, the water inlet 102 and the drain port 103 can be formed at the same end of the outer shell 10 in the length direction, or the water inlet 102 and the drain port 103 are respectively located at both ends of the outer shell 10 in the length direction. It can facilitate the connection of pipelines to the positions of the water inlet 102 and the drain port 103 respectively.

[0106] In some specific examples of the present utility model, an inlet cavity 1211 is defined inside the top cover 12, or the top cover 12 and the housing 11 cooperate to define the inlet cavity 1211, and the inlet cavity 1211 communicates between the water inlet 102 and the inlet 2102 of the filtering structure 20 closest to the water inlet 102.

[0107] The inlet cavity 1211 can provide a buffer space for the condensed water entering the outer shell 10 from the water inlet 102, can temporarily store and gather the condensed water, and guide the condensed water to the inlet 2102 of the filtering structure 20. In this way, the condensed water entering from the water inlet 102 can more smoothly enter the box body 21 through the inlet 2102 of the filtering structure 20, stabilizing the flow rate and velocity of the condensed water entering the box body 21 from the inlet 2102, and improving the filtering efficiency of the filtering structure 20.

[0108] In a specific example of the present utility model, as Figure 6 shown, an overflow channel 104 is further defined inside the outer shell 10, and the overflow channel 104 communicates between the inlet cavity 1211 and the drain port 103.

[0109] When the condensed water cannot flow smoothly into the filtering structure 20, the condensed water in the inlet cavity 1211 can be discharged to the position of the drain port 103 through the overflow channel 104, and then discharged into the water storage tank of the outdoor component 400. In this way, it can prevent the leakage of condensed water and ensure the cleanliness and tidiness of the surrounding environment of the water treatment device 100.

[0110] In some specific examples of the present utility model, as Figure 6As shown, the top cover 12 is formed with a boss portion 121. The boss portion 121 is formed by upward bulging of a part of the top cover 12. The water inlet 102 is formed in the boss portion 121. The inner side of the boss portion 121 defines a water inlet cavity 1211. An overflow observation hole is formed on the side wall of the boss portion 121. The entrance of the overflow channel 104 is lower than the overflow observation hole.

[0111] In this embodiment, the boss portion 121 is provided on the top cover 12. The boss portion 121 can increase the structural strength of the top cover 12 and improve the structural strength and reliability of the water treatment device 100. Among them, the boss portion 121 can be formed at the end of the top cover 12 in the length direction or between the two ends of the top cover 12 in the length direction. Further, the inner side of the boss portion 121 defines a water inlet cavity 1211. In this way, the volume of the water inlet cavity 1211 can be increased, further stabilizing the flow rate and velocity of the condensed water entering the box body 21 from the inlet 2102 and improving the filtration efficiency of the filtration structure 20. At the same time, by providing the overflow observation hole, it is convenient to observe whether the water treatment device overflows, so as to observe whether the water treatment device cannot work properly.

[0112] In some specific examples of the present utility model, as Figure 5 shown, the housing 11 is snap-connected to the top cover 12.

[0113] For example, a plurality of buckles can be formed on the top cover 12. The plurality of buckles are arranged at intervals along the circumferential direction of the top cover 12. The plurality of buckles extend downward toward the housing 11. The buckles are formed in a plate shape. A card hole penetrating the buckle in the rear direction is formed on the buckle. A plurality of card protrusions are provided on the peripheral edge of the housing 11. The plurality of card protrusions correspond to the plurality of buckles one by one. The card protrusions are adapted to be snapped into the card holes of the corresponding buckles.

[0114] Among them, a sealing member can be provided between the housing 11 and the top cover 12. The sealing member extends in a ring shape along the circumferential direction of the top cover 12 and is hermetically abutted between the housing 11 and the top cover 12.

[0115] In this embodiment, the snap connection between the housing 11 and the top cover 12 can improve the connection reliability between the top cover 12 and the housing 11, and is convenient for disassembly and assembly, improving the assembly efficiency.

[0116] In an example of the present utility model, reinforcing ribs are provided on the inner surface of the top cover 12, and the structures of the reinforcing ribs at both ends of the top cover 12 in the length direction are different.

[0117] The number of the reinforcing ribs can be multiple. The multiple reinforcing ribs are arranged at intervals along the circumferential direction of the top cover 12. Among them, the reinforcing ribs can be formed in a long strip shape extending in the up and down direction. In this embodiment, by providing a plurality of reinforcing ribs on the top cover 12, the structural strength of the fixed cover can be enhanced, and the stability and reliability of the top cover 12 can be improved.

[0118] In addition, the structures of the reinforcing ribs at both ends of the top cover 12 in the length direction of this embodiment are different, and the positions on the housing 11 corresponding to the reinforcing ribs are adapted to the shapes of the reinforcing ribs. In this way, during the assembly process, the reinforcing ribs at both ends can play a role in preventing misassembly, avoiding the top cover 12 from being installed in the wrong direction, and improving the assembly efficiency.

[0119] In some specific examples of the present utility model, such as Figure 6 As shown, a plurality of filtering structures 20 are arranged in layers in the up-and-down direction in sequence. The inlets 2102 and outlets 2103 of the filtering structures 20 are respectively located at both ends in the length direction of the box body 21, and the positions of the inlets 2102 and outlets 2103 of two adjacent filtering structures 20 are opposite.

[0120] In this embodiment, a plurality of filtering structures 20 are arranged in layers in the up-and-down direction in sequence, which can make full use of the vertical space and reduce the floor area of the water treatment device 100. At the same time, the inlets 2102 and outlets 2103 of the filtering structures 20 are respectively arranged at both ends of the box body 21, and the positions of the inlets 2102 and outlets 2103 of two adjacent filtering structures 20 are opposite. In this way, when the condensed water flows out from the outlet 2103 of the filtering structure 20 located on the upper side, it can directly enter the inlet 2102 of the next filtering structure 20, so that no additional connection structure needs to be provided, simplifying the structure of the filtering channel and improving the efficiency. At the same time, the filtering channel inside the water treatment device 100 can extend reciprocally along the length direction of the box body 21 in the up-and-down direction. In this way, on the premise of ensuring the length of the filtering channel, the structure of the water treatment device 100 can be made compact and the space occupation can be reduced.

[0121] In an example of the present utility model, such as Figure 5 As shown, the water treatment device 100 may further include: a drain pipe 40, one end of the drain pipe 40 is connected to the drain port 103, and the other end of the drain pipe 40 communicates with the water storage tank of the outdoor component 400. Further, the drain pipe 40 is a silica gel pipe.

[0122] In an example of the present utility model, such as Figure 5 As shown, the water treatment device 100 further includes a water inlet pipe 50 and a water inlet joint 60. The number of the water inlet pipes 50 is multiple. One end of the water inlet joint 60 is connected to the water pump through the water inlet pipe 50, and the other end of the water inlet joint 60 is connected to the water inlet 102 through the water inlet pipe 50. The water inlet pipe 50 is a silica gel pipe.

[0123] In an example of the present utility model, the width of the water treatment device 100 is less than or equal to 35 mm. For example, the width of the water treatment device 100 in the front-rear direction is 30 mm. Thus, the space occupation can be reduced, and the filtering requirements and installation requirements of more than 90% of the kitchen scenarios can be satisfied simultaneously.

[0124] As shown Figures 1 - 3 in FIG. Figures 1 - 3 , the kitchen air conditioner 1000 according to the second aspect embodiment of the present utility model includes a chassis 200, an indoor component 300, an outdoor component 400, and a water treatment device 100 according to the first aspect embodiment of the present utility model. Specifically, both the indoor component 300 and the outdoor component 400 are disposed on the chassis 200, that is, the kitchen air conditioner 1000 of this embodiment is an integral air conditioner. The indoor component 300 includes a water receiving tray, the outdoor component 400 is formed with a water storage tank, the inlet of the water pump is communicated with the water receiving tray, the drain port 103 is communicated to the water storage tank, and at least one filter member 22 of the filter structure 20 is an oil-absorbing member 22a for adsorbing grease.

[0125] It should be noted that for the kitchen air conditioner 1000, since a large amount of oil fume is generated in the environment where the kitchen air conditioner 1000 is located, for the evaporator 310 of the indoor component 300, a large amount of grease and dust will be adsorbed on the surface. When condensed water forms on the surface of the evaporator 310, the grease and dust will drip into the water receiving tray together with the condensed water, making the water in the water receiving tray contain a large amount of oily substances. If the condensed water in the water receiving tray is directly discharged to the water storage tank of the outdoor component 400 and then consumed by the water-consuming module, it will dirty the condenser 410 in the outdoor component 400, and even cause the problem of dirty blockage between the various pipelines of the kitchen air conditioner 1000, resulting in corrosion of each component of the kitchen air conditioner 1000.

[0126] According to the kitchen air conditioner 1000 of the embodiment of the present utility model, by providing the water treatment device 100 of the first aspect embodiment, the water treatment device 100 is provided with a plurality of filter structures 20, and at least one filter member 22 in the filter structure 20 is an oil-absorbing member 22a. The oil-absorbing member 22a can adsorb the grease substances in the condensed water, and at the same time, the plurality of filter structures 20 can cooperate with each other to filter and purify the impurities in the condensed water. In this way, the purity of the condensed water can be improved, the probability of pollution and corrosion of the outdoor component 400 of the kitchen air conditioner 1000 can be reduced, the operation stability of the kitchen air conditioner 1000 can be improved, and the service life of the kitchen air conditioner 1000 can be extended. In addition, the water treatment device 100 of this embodiment can transport the condensed water generated indoors to the outdoor component 400 after purification treatment, without discharging the condensed water generated by the indoor component 300 outdoors, avoiding disturbing pedestrians due to the discharged condensed water, thereby improving the overall performance of the kitchen air conditioner 1000.

[0127] According to some embodiments of the present utility model, as Figure 1 and Figure 2 shown in FIG. Figure 2 , the indoor component 300 and the outdoor component 400 are arranged at intervals and cooperate with the chassis 200 to enclose an arrangement space. The water treatment device 100 is disposed in the arrangement space and is fixedly connected to the indoor component 300 and / or the outdoor component 400.

[0128] Among them, the indoor component 300 and the outdoor component 400 are arranged at intervals, which can reduce the heat exchange between the indoor component 300 and the outdoor component 400 and improve the working efficiency of the kitchen air conditioner 1000. And at this time, the indoor component 300, the outdoor component 400 and the chassis 200 together form a U-shaped structure, and the water treatment device 100 is arranged inside the U-shaped structure. Thereby, the space utilization rate can be improved and the space occupation can be reduced.

[0129] In some embodiments of the present invention, such as Figure 1 and Figure 2 shown, the kitchen air conditioner 1000 can be integrated with the ceiling 500. Among them, the ceiling 500 includes the ceiling 500 and the secondary keel 600, and both the ceiling 500 and the secondary keel 600 are aluminum gusset plates. The indoor component 300, the outdoor component 400 and the chassis 200 of the kitchen air conditioner 1000 form a large U shape, and the indoor component 300, the outdoor component 400 and the chassis 200 together constitute the air-conditioning main device of the kitchen air conditioner 1000.

[0130] After the kitchen air conditioner 1000 is installed, it is located on both sides of the secondary keel 600. The water treatment device 100 is suspended above the secondary keel 600. The water treatment device 100 is fixed to the water consumption module (water pumping device 440 + condenser 410) of the outdoor component 400. At the same time, most of the weight of the water treatment device 100 is concentrated on the drainage device of the indoor component 300 and the top cover 12 of the water consumption module of the outdoor component 400. Thereby, the volume of the kitchen air conditioner 1000 can be significantly reduced, the available space inside the ceiling 500 is increased, the water treatment device 100 is firmly connected to the indoor component 300 and the outdoor component 400, no independent assembly position is required, and no additional bracket is required for fixing. The suspension installation of the water treatment device 100 is carried out after the installation of the air-conditioning main device is completed.

[0131] Among them, the water treatment device 100 is connected to the side plate body of the water consumption module of the outdoor component 400. During maintenance, only the screws of the water treatment device 100 need to be removed to replace or repair the water treatment device 100, and the water treatment device 100 can be quickly installed.

[0132] In a specific example, such as Figure 1As shown, the kitchen air conditioner 1000 is formed with a first air outlet 340, a second air outlet 350, a third air outlet 480 and a fourth air outlet 490. Among them, the first air outlet 340 and the second air outlet 350 are formed on the indoor component 300. The first air outlet 340 is the main indoor return air outlet, and the second air outlet 350 is the indoor return air outlet. The third air outlet 480 and the fourth air outlet 490 are formed on the outdoor component 400. The third air outlet 480 is the outdoor side air outlet, and the fourth air outlet 490 is the indoor return air outlet. Among them, the first air outlet 340 and the second air outlet 350, together with the indoor air duct and the indoor air outlet in the indoor component 300, constitute an indoor air circulation loop. The third air outlet 480 and the fourth air outlet 490, together with the outdoor air duct in the outdoor component 400, constitute an outdoor air circulation loop. Among them, in order to enable indoor air to smoothly enter the first air outlet 340, the second air outlet 350 and the fourth air outlet 490 of the kitchen air conditioner 1000 above the ceiling 500, air inlet grilles are provided on the aluminum gusset plates of the ceiling 500 to suck the air in the indoor environment and achieve air return.

[0133] In the related art, the overall shape of the air conditioner is short and fat, with a relatively wide width. There are few users who can meet the size installation requirements on the market, and the appearance of the air outlet position is average, basically blowing directly at the user's face, resulting in a relatively poor user experience. In the embodiment of the present invention, the air conditioner main body device is flat and square, with a width of 560mm * 560mm, which can meet the installation requirements of more than 90% of the internal space of the kitchen ceiling 500 without damaging the ceiling 500. At the same time, the air outlet position of the air conditioner main body device in this embodiment is relatively high and close to the ceiling, and can achieve the same effect as the sinking air supply mode of conventional multi-connected units, with a relatively good user experience.

[0134] Next, reference will be made to Figures 1 - 12 Describe the kitchen air conditioner 1000 according to a specific embodiment of the present invention.

[0135] Refer to Figure 3 As shown, the kitchen air conditioner 1000 in this embodiment is an integral air conditioner. The kitchen air conditioner 1000 includes: a chassis 200, a water treatment device 100, an indoor component 300 and an outdoor component 400. The indoor component 300 and the outdoor component 400 are arranged at intervals in the front-rear direction on the upper side of the chassis 200. The indoor component 300 includes an evaporator 310, an indoor housing 320 and an indoor fan 330. The outdoor component 400 includes a condenser 410, a compressor 430, a sound insulation cover 450, an outdoor electronic control 420, a water injection device 440, an outdoor fan 460 and an outdoor housing 470. Among them, the sound insulation cover 450 covers the outside of the compressor 430. The chassis 200, the indoor component 300 and the outdoor component 400 are arranged in a U shape and enclose a layout space, and the water treatment device 100 is arranged in the layout space.

[0136] Refer to Figures 4 - 6, the water treatment device 100 includes a water pump, a water inlet pipe 50, a water inlet joint 60, a housing 10, four filtering structures 20, and a drain pipe 40. Among them, the water inlet pipe 50 is a silicone tube. The two ends of the water inlet joint 60 are respectively connected to the water pump and the water inlet 102 of the housing 10 through the water inlet pipe 50. The multiple filtering structures 20 are vertically stacked and assembled in a palletizing structure inside the housing 10. Among them, the drain port 103 is arranged at the bottommost layer of the housing 10. The drain pipe 40 is a silicone tube and is tightly connected to the drain port 103.

[0137] The four filtering structures 20 include a first filtering structure 20a, a second filtering structure 20b, a third filtering structure 20c, and a fourth filtering structure 20d arranged in sequence from top to bottom. Among them, each filtering structure 20 is formed with three sub-chambers 21011. Along the water flow direction, the filtering elements 22 in the three sub-chambers 21011 of the first filtering structure 20a are, in sequence: an antibacterial agent, alumina 22b, and alumina 22b. The filtering elements 22 in the three sub-chambers 21011 of the second filtering structure 20b are all oil-absorbing felts. Among the multiple sub-chambers 21011 of the third filtering structure 20c and the fourth filtering structure 20d, the filtering elements 22 are alumina 22b and activated carbon, and the alumina 22b and the activated carbon are alternately arranged along the water flow direction.

[0138] When the kitchen air conditioner 1000 operates, the condensed water flows from the evaporator 310 fins into the water receiving tray. The water level switch starts to float up to detect the water storage position, the water pump starts to pump water, and the determination control is carried out according to the detection result of the water level switch float.

[0139] In the normal state, the water pump pumps the water into the water inlet pipe 50, sends it from the water inlet joint 60 to the water inlet 102 on the housing 10, and then enters the box body 21 of the filtering structure 20 from the inlet 2102 at the top of the box body 21.

[0140] The water path sequentially passes through the first sub-chamber 21011 of the first filtering structure 20a from the upper right. The first sub-chamber 21011 is filled with the long-acting antibacterial substance blue antibacterial agent, which can preliminarily filter the free radicals causing blockage in the water. The filtered water sequentially flows into the other two sub-chambers 21011, and the impurities in the condensed water are filtered by the activated alumina 22b.

[0141] Then, the condensed water flows downward into the second filtering structure 20b. In the second filtering structure 20b, the oil filtered by the oil-absorbing felt is blocked in the three sub-chambers 21011. In the three sub-chambers 21011, using the principle of communicating vessels and the principle that oil floats on the upper layer, the oil in the condensed water is adsorbed into the interior of the oil-absorbing felt, and the water flows out through the gap on top of the oil-absorbing felt.

[0142] In the second filtering structure 20b, the problem of condensate water-oil separation can be solved, and the filtering and purifying effect of antibacterial softening separation can be achieved. Among them, during the process from one sub-chamber 21011 to another sub-chamber 21011 of the second filtering structure 20b, the upper edge of the partition plate 213 is lower than the upper surface of the oil-absorbing felt, and the distance between the upper end surface of the partition plate 213 and the upper surface of the oil-absorbing felt is greater than or equal to 0.5 mm and less than or equal to 2 mm. In this way, the position of the partition plate 213 can produce a drainage effect on grease and water.

[0143] After that, the filtered water flows downward into the third filtering structure 20c and the fourth filtering structure 20d, and performs a "Z"-shaped filtration on the organic carboxylic acid (which can cause corrosion of copper pipes and fins) component in the water. The filtered clean condensate water flows out through the drain port 103 and flows into the water storage tank of the outdoor component 400, and the condensate water in the water storage tank is consumed by the water pumping device 440.

[0144] Among them, the above four filtering structures 20, by adopting different filtering elements 22, realize the combination of physical filtration and chemical purification, control the condensate water to complete multi-stage filtration of bacteria removal, oil removal and acid removal in the "Z"-shaped filtering channel. After the ions containing organic carboxylic acids in the condensate water are neutralized, the rapid purification of the condensate water is realized, and the water quality of the condensate water is restored to an oil-free scenario.

[0145] In addition, for the water treatment device of this embodiment, when the condensate water flows from the water inlet 102 to the inlet 2102 position of the filtering structure 20, the inlet 2102 position of the box body 21 is provided with an inlet grille 214. The inlet grille 214 can play the role of filtering the manhole. When the water flow is large, it can isolate the natural flow of water and reduce the impact force on the filtering element 22. At the same time, it can prevent the condensate water from overflowing during high-speed flow, thereby improving the efficiency and stability of the water flow path.

[0146] The kitchen air conditioner 1000 of the embodiment of the present utility model, by setting the water treatment device 100, can solve the problem that the sewage stored outside the integrated air conditioner affects the service life of the air conditioner, can solve the problem of dripping complaints caused by the stored water, and can effectively filter and purify the grease and organic carboxylic acid components in the kitchen condensate water, reducing the risk of certain fouling and corrosion to the fins and copper pipes of the condenser 410 in the outdoor component 400.
