The filtering apparatus 100 and the air conditioner 200 according to the embodiment of the present invention are described below with reference to the accompanying drawings.

As shown in fig. 1 and 2, an air conditioner 200 according to an embodiment of the present invention includes a filtering device 100 according to an embodiment of the present invention. For example, the filtering apparatus 100 may be used for at least one of an indoor unit and an outdoor unit of the air conditioner 200.

In the related art, some air conditioning equipment with a humidifying function can adjust indoor relative humidity, but the air conditioning equipment is generally complex in structure and difficult to operate in water adding, and a user needs to add water on time in the using process, so that the using difficulty of the user is increased, and the using experience of the user is reduced.

Therefore, in some embodiments of the present invention, the filtering device 100 may be used to filter condensed water (such as removing impurities such as dust) generated during the operation of the air conditioner 200, so that the filtered condensed water can be used for a humidifying function, which reduces the frequency of water adding by a user or does not need to manually add water by the user, thereby improving the use experience.

In other embodiments of the present invention, the filtering apparatus 100 may also be used to filter water manually added by a user to improve the quality of the water used for humidification, avoiding scaling or clogging of the humidification components. Specifically, the air conditioner 200 may have a water tank 210, and the filtering device 100 may communicate with a water pipe of the water tank 210 so as to filter the liquid in the water tank 210.

Of course, in addition to the humidification function, in still other embodiments, the filter apparatus 100 may be used for other functions, only where it is required to filter a liquid.

In addition, the air conditioner 200 is generally installed in a place where a human hand is not easily touched, and the filter 20 of the filtering apparatus 100 needs to be replaced after being used for a period of time in order to ensure the filtering effect. Therefore, it is necessary to ensure that the filter 20 is fixed and stable in a state of being mounted to the air conditioner 200, avoid the risk of falling off, and ensure that the disassembly process is simple and easy to operate.

Referring to fig. 2 to 13, a filtering apparatus 100 according to an embodiment of the present invention may include: mount 10, filter 20 and lock 30.

In some embodiments in which the filter apparatus 100 is mounted to the air conditioner 200, as shown in fig. 1 and 2, the air conditioner 200 may include a housing to which the mount 10 is mounted, so that a user can easily detach and mount the filter 20 from the outside of the housing. For example, the mounting base 10 may be mounted on the face frame 220 of the housing, and the mounting base 10 is exposed after the panel of the housing is opened, so as to facilitate the disassembly of the filter 20. The mounting base 10 and the face frame 220 may be separate members, and the mounting base 10 may be integrally formed with the face frame 220, which is within the scope of the present invention.

Specifically, the mount 10 has a mounting cavity 101, and the filter 20 is detachably mounted in the mounting cavity 101. The cavity mouth of the installation cavity 101 may be formed as a mounting/dismounting mouth for mounting/dismounting the filter 20, for example, as shown in fig. 1 and 2, the cavity mouth of the installation cavity 101 may be directed toward the front side of the air conditioner 200, the user may push the filter 20 backward so that the filter 20 is installed into the installation cavity 101, and the user may pull the filter 20 forward so that the filter 20 is removed from the installation cavity 101, facilitating replacement of the filter 20.

Further, the lock member 30 is mounted to the mount 10, and the lock member 30 is rotatable relative to the mount 10 between a locked position and an unlocked position.

As shown in fig. 6 and 7, in the state that the locking member 30 is in the locking position, the locking member 30 can lock the filter 20 to fix the filter 20 in the installation cavity 101, so that on one hand, the filter 20 is prevented from falling off to damage or injure a user by smashing, and on the other hand, the reliable connection between the filter 20 and the liquid pipeline of the air conditioner 200 can be ensured, and the reliability and the sealing performance of the filtration can be improved.

As shown in fig. 12 and 13, in the state that the locking member 30 is in the unlocked position, the locking member 30 can unlock the filter 20, and at this time, the filter 20 can move relative to the mounting seat 10 to be removed from the mounting cavity 101, so that the user can replace the filter 20 conveniently, and the filtering effect of the filtering device 100 is ensured.

The locking piece 30 realizes the state switching of locking and unlocking through rotating, the user operation is simple, the locking structure of the filter 20 is also simple, the filter 20 is prevented from being separated, the filter 20 is convenient to assemble and disassemble, and the user experience is improved.

According to the filter device 100 provided by the embodiment of the invention, the filter 20 is arranged in the installation cavity 101, the locking piece 30 is rotated to switch the locking and unlocking states of the filter 20, so that the filter 20 is not easy to separate after being installed in place, the use safety is improved, the filter 20 can be detached by rotating the locking piece 30 and pulling the filter 20, the filter 20 is conveniently taken out, and the user operation is convenient.

Since the filter device 100 according to the embodiment of the invention has the beneficial technical effects described above, according to the air conditioner 200 of the embodiment of the invention, the filter 20 is installed in the installation cavity 101, and the locking piece 30 is rotated to switch the locking and unlocking states of the filter 20, so that the filter 20 is not easy to be separated after being installed in place, the use safety is improved, and the filter 20 can be detached by rotating the locking piece 30 and pulling the filter 20, so that the filter 20 is taken out conveniently, and the operation is convenient for a user.

According to some embodiments of the invention, as shown in fig. 6-8 and 12-13, the locking member 30 is provided with a driving portion 35, the filter 20 is provided with a driving engagement portion 21, and the driving portion 35 is located on a side of the driving engagement portion 21 remote from the cavity opening of the mounting cavity 101, e.g. in embodiments in which the mounting cavity 101 is open towards the front, the driving portion 35 is located on a rear side of the driving engagement portion 21.

Thus, in the process that the locking piece 30 rotates from the locking position to the unlocking position, the driving part 35 can prop against the driving matching part 21 and push the driving matching part 21 to move towards the cavity opening of the installation cavity 101, so that the filter 20 is driven to move outwards of the installation cavity 101, and when the locking piece 30 moves to the unlocking position, at least one part of the filter 20 can be positioned outside the installation cavity 101, so that a user can pull the filter 20 through the part positioned outside the installation cavity 101, and the filter 20 is detached. That is, by rotating the locking member 30, not only unlocking but also preliminary disassembly of the filter 20 is achieved, convenience of user operation is improved, and the filter 20 can be disassembled and assembled by one hand.

In some embodiments, as shown in fig. 13, the two sides of the mouth of the mounting cavity 101 can be deformed away from each other to form a catch slot 102, which can increase the space available for the user to operate when the locking member 30 is used to drive the filter 20 out, and which can clamp the filter 20 from the space at the catch slot 102 to pull the filter 20 out when the locking member 30 fails to drive the filter 20 out.

In some embodiments, as shown in fig. 6-8, during installation of the filter 20, such as during movement of the filter 20 from front to back into the installation cavity 101, the drive engagement portion 21 may also abut against the drive portion 35, driving the drive portion 35 to move back and rotate the locking member 30 from the unlocked position to the locked position. Therefore, the filter 20 can be locked while the filter 20 is inserted into the mounting cavity 101, so that the filter 20 after replacement can be stably mounted, and the operation steps of a user are further simplified.

The specific structures of the driving part 35 and the driving matching part 21 are not particularly limited, and only the requirement that the driving part 35 and the driving matching part can be matched against each other to realize transmission in the process of rotating and unlocking the locking piece 30 and the process of moving the filter 20 into the mounting cavity 101 is met.

For example, as shown in fig. 6 to 8, the locking member 30 includes a connecting arm 31, one end of the connecting arm 31 is rotatably engaged with a cavity wall of the mounting cavity 101, and the driving portion 35 may be a protrusion provided on an outer peripheral surface of one end of the connecting arm 31, so that one end of the connecting arm 31 is formed as a cam structure. The driving engagement portion 21 may be a protrusion provided on the surface of the filter 20, such as an upper protrusion provided on the upper surface of the filter 20. So that the contact matching position with the upper protrusion changes in size from the rotation axis during the rotation of the cam structure, thereby driving the upper protrusion to move. The other end of the connecting arm 31 may be provided as an operation end of the user or may be provided with a structure for the user to perform an operation, so that the locking member 30 may be formed in a lever structure to make it more labor-saving for the user to rotate the locking member 30 to unlock and push the filter 20 out of the installation cavity 101.

In some embodiments, as shown in fig. 8, the outer peripheral surfaces of the driving portion 35 and the driving engagement portion 21 may be smooth cambered surfaces, so as to reduce friction resistance between the driving portion 35 and the driving engagement portion 21, reduce wear of the two,

the locking structure of the locking member 30 according to some embodiments of the present invention is described below with reference to the accompanying drawings.

According to some embodiments of the present invention, as shown in fig. 3-8, the locking member 30 may include a connection arm 31 and a locking portion 32. Wherein, one end of the connecting arm 31 is rotatably installed on the cavity wall of the installation cavity 101, and the locking part 32 is provided on the other end of the connecting arm 31. In the state in which the locking member 30 is in the locking position, the locking portion 32 is stopped at a side of the filter 20 facing the mouth of the installation cavity 101, for example, a front side as shown in fig. 7, thereby preventing the filter 20 from being pulled out of the installation cavity 101, and ensuring stable installation of the filter 20.

In some embodiments, with continued reference to fig. 3-8, the locking portion 32 may be a locking plate, one side edge of which (the upper side edge as shown in fig. 7) is connected to the connecting arm 31, and the other side edge of which (the other side as shown in fig. 7) abuts against the filter 20. The mating structure of the connecting arm 31 and the locking plate is formed generally in an L-shape.

On one hand, the connecting arm 31 is convenient to rotationally connect with the cavity wall of the mounting cavity 101, and meanwhile, the locking plate is convenient to prop against the filter 20, the contact area can be larger, and the limiting stability is ensured; on the other hand, the direction of the stopping force of the filter 20 to the locking plate faces to the outside of the mounting cavity 101, if the stopping force is forward, the stopping force of the filter 20 can not push the locking piece 30 to rotate and unlock, so that the locking reliability is ensured, and when unlocking is needed, a user can push the locking plate upwards (in the direction shown by an arrow F in fig. 10) to drive the connecting arm 31 to rotate, so that the unlocking of the user is labor-saving.

In order to improve structural stability of the locking member 30, as shown in fig. 3 to 7, the number of the connection arms 31 may be two, and the two connection arms 31 are respectively mounted to two cavity walls of the mounting cavity 101 opposite to each other, such as the left cavity wall and the right cavity wall shown in fig. 3. The two connecting arms 31 are connected to both ends of the locking portion 32 in the longitudinal direction, respectively, so that the locking member 30 is formed in a generally C-shaped structure. The locking part 32 can stop and limit the filter 20 in a wider range in the width direction of the filter 20, so that the filter 20 is prevented from falling out more effectively; and the locking piece 30 is connected with the mounting seat 10 more stably, and the locking and other problems are not easy to happen in the rotation process.

In some embodiments, as shown in fig. 3-6, the locking member 30 has a pivot 33, e.g., the pivot 33 may be provided at one end of the connecting arm 31, the pivot 33 rotatably engaging the wall of the mounting cavity 101 to provide support for rotation of the locking member 30 between the unlocked and locked positions. For example, as shown in fig. 3 to 6, two opposite side walls of the mounting cavity 101 may be provided with mounting grooves 103, respectively, and opposite side surfaces of the two connecting arms 31 of the locking member 30, which are opposite to each other, are provided with rotating shafts 33, and the rotating shafts 33 are inserted into the corresponding mounting grooves 103 to rotate in the mounting grooves 103.

In addition, the wall of the installation cavity 101 may be provided with a limit protrusion 11, for example, the bottom wall of the installation groove 103 may be provided with a limit protrusion 11. And the outer circumferential surface of the rotating shaft 33 may be provided with the fitting convex portion 34.

When the locking member 30 is in the unlocking position, as shown in fig. 12 to 13, one side of the limit projection 11 (the upper side as shown in fig. 12 and 13) may abut against the fitting projection 34 to hold the locking member 30 in the unlocking position. Therefore, after the user removes the filter 20, the locking member 30 will not rotate to the locking position under the limit action of the limit protrusion 11, so that the locking member 30 will not interfere with the filter 20 when the user inserts a new filter 20 into the installation cavity 101, and the user can install the filter 20 with one hand. For example, when replacing the filter 20, other tools such as a ladder are usually needed, after a person climbs the ladder, the person holds the ladder with one hand, and the other hand realizes the disassembly and assembly of the filter 20, so that the operation safety is ensured.

With the locking member 30 in the locked position, as shown in fig. 3-6, the other side of the limit projection 11 (the lower side as shown in fig. 4) may abut against the mating projection 34 to hold the locking member 30 in the locked position. Therefore, the locking piece 30 can ensure stable limit of the filter 20, and the effect of preventing the filter 20 from being separated is better. When the filter 20 needs to be taken out, the user can push the locking piece 30 upwards to enable the locking piece 30 to rotate upwards, and the matching bulge passes over the limit protrusion 11 and moves to one side of the limit protrusion 11 under the action of external force, so that unlocking is completed.

According to some embodiments of the present invention, as shown in fig. 3 and 6, the wall of the installation cavity 101 may be provided with a guiding portion 12, the guiding portion 12 extending in the depth direction of the installation cavity 101, i.e. the guiding portion 12 extends perpendicular to the plane of the cavity mouth of the installation cavity 101. The filter 20 is provided with a guide engaging portion 22 for engaging with the guide portion 12. One of the guide portion 12 and the guide engaging portion 22 is a guide groove, and the other of the guide portion 12 and the guide engaging portion 22 is a guide projection. In the process of installing the filter 20 into the installation cavity 101, the guide protrusion can extend into the guide groove and move along the guide groove so as to realize the guide of the installation of the filter 20, ensure that the filter 20 can be smoothly installed in place in the installation cavity 101, and facilitate the accurate communication of waterways.

According to some embodiments of the present invention, as shown in fig. 9-11, the filter 20 may have a first water pipe 23, the first water pipe 23 extending in the depth direction of the installation cavity 101, i.e. perpendicular to the plane of the cavity mouth of the installation cavity 101, in other words, the extending direction of the first water pipe 23 is the same as the moving direction of the filter 20 into the installation cavity 101.

In some embodiments, as shown in fig. 12, at least a portion of the first water pipe 23 may be provided protruding from the outer surface of the filter 20, so that the first water pipe 23 may serve as a guide engaging portion 22 for the disassembly and assembly guide of the filter 20, without providing a guide structure, simplifying the structure of the filter 20.

In some embodiments, as shown in fig. 9-11, a second water pipe 13 may be provided within the installation cavity 101, the second water pipe 13 extending in the depth direction of the installation cavity 101. Therefore, after the filter 20 is installed in the installation cavity 101, the first water pipe 23 and the second water pipe 13 can be in plug-in fit, the filter 20 is movably installed in the installation cavity 101 along the depth direction of the installation cavity 101, and meanwhile, the water paths are connected, so that the assembly process is simplified, and the operation of a user is more convenient.

In some embodiments, as shown in fig. 9 to 11, the filter 20 may be provided with two first water pipes 23, and two second water pipes 13 may be provided in the corresponding installation cavity 101, where the two first water pipes 23 are in one-to-one correspondence with the two second water pipes 13 to form two waterways, and the two waterways are used as a water inlet waterway and a water outlet waterway of the filter 20, respectively.

Wherein, in an embodiment including the water tank 210, at least one of the water inlet waterway and the water outlet waterway may be in communication with the water tank 210. For example, a water inlet waterway is communicated with the water tank 210, so that the liquid stored in the water tank 210 can flow into the filter 20 through the water inlet waterway for filtering, and the filtered liquid can flow into the humidifying assembly through a water outlet waterway for humidifying; for another example, the water outlet channel is communicated with the water tank 210, and condensed water (such as condensed water in the chassis 230 of the air conditioner 200) generated by the operation of the air conditioner 200 can flow into the filter 20 through the water inlet channel for filtering, and the filtered liquid can flow into the water tank 210 through the water outlet channel for storage; for another example, the water tank 210 may have a first chamber and a second chamber, and the liquid stored in the first chamber may flow into the filter 20 through the water inlet path and filtered liquid may flow into the second chamber through the water outlet path.

In some embodiments of the present invention, as shown in fig. 10 to 11 and 14, the first water pipe 23 and the second water pipe 13 may be sealed by interference with the sealing member 40, so that the first water pipe 23 and the second water pipe 13 are convenient to be disassembled and assembled, the tightness is ensured, water leakage is avoided, and the anti-falling effect of the filter 20 is improved.

In the embodiment of the present invention, the specific structure of the sealing member 40 can be flexibly set according to the actual situation.

For example, in some embodiments, as shown in fig. 10 and 11, the seal 40 is a seal ring 41. Taking the example that the first water pipe 23 is inserted into the second water pipe 13, the sealing ring 41 can be sleeved on the first water pipe 23 or embedded in the second water pipe 13, so that the sealing ring 41 is not easy to misplace in the process of disassembly and assembly. And other fixing structures such as a fixing nut and the like are not required to be additionally arranged, so that the assembly structure is simple. In some embodiments, the seal 40 may be a rubber member, a silicone member, or the like.

In the embodiment of the sealing ring 41 sleeved and installed on the first water pipe 23, two rings of blocking ribs can be further arranged on the outer circumferential surface of the first water pipe 23 and are respectively located at two axial sides of the sealing ring 41, so that the sealing effect is prevented from being influenced by dislocation of the sealing ring 41.

The diameter of the sealing ring 41 can be adjusted according to the sizes of the first water pipe 23 and the second water pipe 13, but the following requirements are satisfied. As shown in fig. 11, the radial cross-sectional diameter of the seal ring 41 is D, the outer diameter of the first water pipe 23 is D1, the inner diameter of the second water pipe 13 is D2, and D, D1, and D2 satisfy: 5% < (D- ((D2-D1)/2))/D100% <50%. Within the above-mentioned size range, the seal ring 41 can be pressed and sealed with the outer peripheral surface of the first water pipe 23 and the inner peripheral surface of the second water pipe 13, and the sealing effect is good.
