Description

Technical Field

[0001] This application relates to the field of water treatment and filtration technology, and in particular to a filtration device. Background Technology

[0002] A dehumidifier is an appliance used to reduce indoor humidity. Its basic principle is to separate and condense excess water vapor in the air through processes such as refrigeration or adsorption, thereby achieving the purpose of regulating the humidity of the environment.

[0003] Top-mounted dehumidifiers have a water pump that draws water from the bottom to a drain tank. However, during the pumping process, dust and impurities in the air are drawn into the dehumidifier and collected in the condensate drain. Therefore, impurities in the water can easily clog the pump, leading to pump damage and reduced drainage efficiency. Utility Model Content

[0004] In order to reduce the probability of blockage during water pumping, this application provides a filtration device.

[0005] The filtration device provided in this application adopts the following technical solution: A filtration device includes a collection housing and a water pump. The collection housing has a water collection tank for collecting condensate. It also includes a filtration mechanism disposed in the water collection tank and connected to the input end of the water pump. The filtration mechanism includes a filter bottom shell, a filter element disposed in the filter bottom shell, and a filter cover plate. The filter bottom shell has a plurality of water inlet holes. The filter element and the water inlet holes are correspondingly disposed, and an extraction chamber connected to the water pump is formed between the filter element and the filter cover plate.

[0006] By adopting the above technical solution, the filtration mechanism can filter the condensate in the water collection tank, prevent impurities in the water from clogging the water pump, avoid damage to the water pump, and improve drainage efficiency.

[0007] Optionally, the filter housing is provided with a fixed support lug on its side wall, and the collection housing is provided with a positioning post in the water collection tank that is inserted and engaged with the fixed support lug.

[0008] By adopting the above technical solution, the fixed lugs on the side wall of the filter housing are inserted into the positioning post of the water collection tank of the collection housing, which enables the filter housing to be positioned and installed in the water collection tank of the collection housing, ensuring the accuracy and stability of the installation position of the filter mechanism.

[0009] Optionally, there is an extraction gap between the bottom of the filter housing and the bottom wall of the water collection tank, and the water inlet is located at the bottom of the filter housing.

[0010] By adopting the above technical solution, an extraction gap is set between the bottom of the filter housing and the bottom wall of the water collection tank, and the water inlet is located at the bottom of the filter housing. This allows condensate to flow into the filter mechanism from the bottom better, while avoiding blockage caused by impurities on the bottom wall of the water collection tank directly entering the water inlet, thus reducing the impact of impurities in the water on the water pump.

[0011] Optionally, the filter element includes a filter section abutting against the bottom of the filter housing and an abutting section abutting against the side wall of the filter housing, and the filter section array has multiple filter through holes.

[0012] By adopting the above technical solution, the filter through holes of the filter section can filter the condensate entering the filter mechanism, remove impurities in the water, reduce the probability of water pump damage, and the abutting part abutting against the side wall of the filter bottom shell can better fix the filter element in the filter bottom shell and ensure the filtration effect.

[0013] Optionally, the filter element is a silver-plated stainless steel mesh.

[0014] By adopting the above technical solution and using silver-plated stainless steel mesh, bacterial growth can be inhibited, water quality safety can be improved, filtration efficiency and antibacterial performance can be balanced, and maintenance costs can be reduced.

[0015] Optionally, the filter cover is sealed and installed on the top of the filter base shell, and the bottom of the filter cover is provided with a pressing side that is interference-inserted into the filter base shell and presses against the contact portion.

[0016] By adopting the above technical solution, the filter cover is sealed and installed on the top of the filter bottom shell. The bottom of the filter cover is inserted into the filter bottom shell with an interference fit and the pressing side of the abutment part is pressed tightly. This can prevent unfiltered water from entering the extraction chamber from the connection between the filter cover and the filter bottom shell, ensuring that the water is filtered by the filter element before being extracted by the water pump.

[0017] Optionally, the bottom of the pressing side is provided with an inclined surface for inserting into the filter base shell.

[0018] By adopting the above technical solution, the inclined surface makes it easier to insert the filter cover into the filter bottom shell during installation, reducing installation difficulty and improving installation efficiency.

[0019] Optionally, the side wall of the filter cover is provided with a plug-in block, the filter bottom shell is provided with a plug-in groove for the plug-in block to be inserted, and the abutment part has a relief groove corresponding to the plug-in block.

[0020] By adopting the above technical solution, the insertion block on the side wall of the filter cover plate is inserted into the insertion groove of the filter bottom shell, which can realize a stable connection between the filter cover plate and the filter bottom shell; the clearance groove of the abutment part provides space for the insertion block, avoids interference, and ensures the normal installation and use of the filter device.

[0021] Optionally, the bottom of the filter cover is also provided with abutment posts for pressing the filter section.

[0022] By adopting the above technical solution and using the spacing of the abutment columns to press the filter part, the filter part can be installed more stably, preventing it from shifting during use and thus ensuring the stability of the filtration effect.

[0023] Optionally, the top of the filter housing is also provided with a notch for removing the filter cover.

[0024] By adopting the above technical solution, the notch groove set on the top of the filter housing facilitates the removal of the filter cover plate, making it easy to clean and maintain the filter mechanism.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The filtration system filters the condensate to prevent dust and impurities from entering the water pump, reducing the risk of pump blockage; 2. An extraction gap is set between the bottom of the filter housing and the bottom wall of the water collection tank, and the water inlet is located at the bottom of the filter housing, which allows condensate to flow into the filter mechanism from the bottom more effectively. 3. By using the bottom of the filter cover plate to be inserted into the filter bottom shell and pressed tightly against the pressing side, unfiltered water can be prevented from entering the extraction chamber from the connection between the filter cover plate and the filter bottom shell, ensuring that all water is filtered by the filter element before being extracted by the water pump.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a filtering device.

[0033] Reference Figure 1 A filtration device includes a collection housing 1, a water pump 2, and a filtration mechanism 3. The top side of the collection housing 1 has a water collection tank 11, which corresponds to the condensation mechanism of the dehumidifier, so that the condensate generated by the condensation mechanism can directly enter the water collection tank 11.

[0034] The water pump 2 is fixed at the bottom of the collection housing 1, with one end connected to the filter mechanism 3 and the other end connected to the drain tank at the top of the dehumidifier.

[0035] Reference Figure 1 and Figure 2 The filtration mechanism 3 includes a filter housing 31, a filter element 32, and a filter cover plate 33. The filter housing 31 is generally a rectangular shell with an open top, and its bottom has an array of water inlet holes 311. The filter element 32 is generally a U-shaped plate with its opening facing upwards, and it includes a filter section 321 arranged on the inner bottom wall of the filter housing 31 and abutment sections 322 connecting opposite sides of the filter section 321. The filter cover plate 33 is sealed and installed on the top of the filter housing 31, and fixes the filter element 32 to the filter housing 31. The filter section 321 has an array of filter through holes 3211, which can filter condensate water passing through the bottom water inlet holes 311.

[0036] Reference Figure 2 and Figure 3 An extraction chamber 34 is formed between the filter element 32 and the filter cover plate 33, and a connecting pipe 35 is provided on the filter housing to connect the extraction chamber 34 and the water pump 2. In this embodiment, the filter element 32 is made of silver-plated stainless steel mesh, which has a certain antibacterial effect and can improve the filtration efficiency.

[0037] The outer wall of the filter base shell 31 is provided with a fixing lug 312, and the collection shell 1 is provided with a positioning post 12 in the water collection tank 11 that is inserted and engaged with the fixing lug 312. In this embodiment, the side wall of the filter base shell 31 is provided with two sets of fixing lugs 312. The bottom of the fixing lug 312 is provided with a positioning slot 3121 that is inserted and engaged with the positioning post 12, and the fixing lug 312 has a through hole in the positioning slot 3121 that penetrates both end faces. Screws pass through the through holes and are fixedly connected to the positioning post 12, thereby fixing the positioning post 12 and the fixing lug 312.

[0038] By setting the positioning column 12 and the fixed support 312, the filter bottom shell 31 is mounted on the water collection tank 11, so that an extraction gap 13 is formed between the end of the filter bottom shell 31 and the bottom wall of the water collection tank 11, so that the water pump 2 can start to extract from the bottom of the water collection tank 11 after starting.

[0039] The bottom of the filter cover plate 33 is integrally provided with a pressing side 331 that is interference-fitted into the filter base shell 31. The pressing side 331 is evenly distributed around the bottom of the filter cover plate 33 so that the filter cover plate 33 can be inserted into the filter base shell 31. The pressing side 331 presses the abutment part 322 against the inner wall of the extraction chamber 34, thereby sealing the filter cover plate 33 and the filter base shell 31. This reduces the probability of unfiltered water entering the filter chamber from the connection between the filter cover plate 33 and the filter base shell 31, ensuring that all water is filtered by the filter element 32 before being extracted by the water pump 2. The pressing side 331 near the connecting pipe 35 also has an arc-shaped through hole 3311, which corresponds to the input end of the connecting pipe 35 to ensure the stability of water delivery.

[0040] The bottom sidewall of the pressing side 331 is also provided with an inclined surface 3312 to improve the installation efficiency of the filter cover 33. To further improve the connection strength between the filter cover 33 and the filter base shell 31, the filter cover 33 is also provided with a plug-in block 332 on the pressing side 331. The filter base shell 31 has a plug-in groove 313 that mates with the plug-in block 332. In this embodiment, the plug-in block 332 is provided on both sides of the pressing side 331 along the length of the filter cover 33, and the bottom of the plug-in block 332 has a guide surface for guiding insertion into the extraction chamber 34. The guide surface and the inclined surface 3312 are in the same inclination direction. The abutment portion 322 of the filter element 32 has a relief groove 323 corresponding to the plug-in block 332.

[0041] The bottom of the filter cover plate 33 is provided with two sets of abutment posts 333 at intervals along the length direction for pressing the filter part 321. The ends of the abutment posts 333 are also provided with reinforcing ribs to improve the structural strength. By setting the abutment posts 333, the stability of the filter element 32 in the filter housing is further improved, and the probability of the filter element 32 shaking when the water pump 2 is pumping is reduced.

[0042] To facilitate the removal of the filter cover plate 33 for maintenance or replacement of the filter element 32 by operators, four sets of notches 314 are provided on the top of the filter base shell 31. The four sets of notches 314 are opposite each other and are respectively arranged on opposite sides of the length direction of the filter base shell 31.

[0043] The implementation principle of a filter device according to an embodiment of this application is as follows: the filter base 31 is initially positioned by the cooperation of the fixing lug 312 and the positioning post 12, and then finally fixed by screws; the filter element 32 and the filter cover plate 33 are installed onto the filter base 31 in sequence, the pressing side 331 is inserted with interference fit, the insertion block 332 and the insertion groove 313 cooperate, and the filter cover plate 33 fixes the filter element 32 in the extraction chamber 34.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
