Disclosure of Invention

Problems to be solved by the utility model

The present utility model has been made in view of the above-described situation, and an object of the present utility model is to provide a washing member capable of improving washing performance, a filter assembly including the washing member, and a drum-type laundry treatment apparatus including the filter assembly.

Solution for solving the problem

In order to achieve the above object, the present utility model provides a flushing member including a flushing member housing in which a water inlet for introducing flushing water into an inner chamber of the flushing member housing is formed, the inner chamber including a first chamber communicating with the water inlet and having a first water outlet for discharging flushing water from the first chamber to the second chamber, a second chamber having a second water outlet for discharging flushing water from the second chamber to the third chamber, and a third chamber having a third water outlet for discharging flushing water toward a flushing object, the opening area of the first water outlet being smaller than that of the water inlet.

Because the inner chamber of the flushing member includes the first chamber, the second chamber and the third chamber, flushing water can be caused to flow into each chamber step by step, so that the flow of flushing water can be rectified conveniently. Further, since the opening area of the first water outlet of the first chamber of the flushing member is smaller than the opening area of the water inlet, it is possible to ensure that flushing water is discharged from the first water outlet to the second chamber when the first chamber is filled, and to more uniformly flow flushing water from the first chamber to the second chamber, and to prevent uneven flushing of the flushing target due to water and air bubbles, and to thereby more uniformly flush the flushing target, and to improve the water pressure of the flushing water, and to thereby improve flushing performance.

Preferably, the position of the upper end edge in the height direction of the second water outlet is lower than the center position in the height direction of the first water outlet.

When the first chamber is filled with water, the upper surface of the water in the first chamber is liable to form water bloom and becomes unstable. That is, the upper portion of the water flow flowing out from the first water outlet is liable to become unstable. By positioning the upper edge of the second water outlet in the height direction below the center position of the first water outlet in the height direction, a relatively stable lower portion of the water flow flowing out of the first water outlet can be ensured to be discharged from the second water outlet to the third chamber. This can more uniformly discharge the flush water from the third discharge port of the third chamber, and can further improve the flushing performance.

Preferably, the opening area of the first water outlet is larger than the opening area of the third water outlet.

Since the opening area of the first water outlet is larger than the opening area of the third water outlet, the water pressure of the washing water discharged from the third water outlet can be further increased, and thus the washing ability can be further improved.

Preferably, the first water outlet includes a plurality of first water outlet holes uniformly arranged along an extending direction of the inner chamber.

Since the first water outlet includes the plurality of first water outlet holes uniformly arranged along the extending direction of the inner chamber, it is possible to ensure more uniform water flow discharged from the first water outlet, thereby enabling more uniform discharge of the washing water from the third water outlet, and further improving the washing ability.

Preferably, the third water outlet includes a plurality of third water outlet holes uniformly arranged along an extending direction of the inner chamber.

Since the third water outlet includes the plurality of third water outlet holes uniformly arranged along the extending direction of the inner chamber, the washing water can be more uniformly discharged from the third water outlet, and the washing ability can be further improved. Further, the structure in which the third water outlet includes the plurality of third water outlet holes uniformly arranged along the extending direction of the inner chamber can improve the strength of the wall portion in which the third water outlet is formed, as compared with the case in which the third water outlet includes the continuous elongated hole extending along the extending direction of the inner chamber.

Preferably, the flushing member housing includes a top wall, a bottom wall, and side walls constituting the internal chamber, and the second water outlet is formed by an elongated gap formed between a rib protruding from the top wall toward the bottom wall and extending in the extending direction of the internal chamber and the bottom wall and extending in the extending direction of the internal chamber.

By forming the second water outlet by using the elongated gap formed between the rib protruding from the top wall and the bottom wall, the second water outlet can be formed with a simple structure, and unstable water flow can be reliably blocked.

Preferably, the flushing member housing includes a first flushing member housing and a second flushing member housing, the water inlet being formed in the first flushing member housing, the internal chamber being formed by combining the first flushing member housing and the second flushing member housing together.

By combining the first flushing member housing and the second flushing member housing to form the internal chamber, the internal chamber having the first to third chambers can be easily formed, and the design of the water outlet of each chamber can be easily performed.

The present utility model provides a filter assembly comprising: the filter comprises a filter shell, wherein a filter air channel is formed in the filter shell, and the filter shell is provided with a filter air channel inlet for air to flow into the filter air channel and a filter air channel outlet for air to flow out of the filter air channel; a filter device provided in the filter duct and having a filter screen for filtering foreign matters in air flowing in the filter duct, the filter device having a filter frame to which the filter screen is fixed; and the flushing member is mounted on the filter frame in a manner of flushing the windward side of the filter screen by flushing water discharged from the third water outlet.

In the filter unit, the foreign matter such as lint on the filter screen can be efficiently washed off by the washing member.

Preferably, the flushing member housing is provided with a water inlet protruding therefrom, the water inlet is provided with the water inlet, a seal ring is externally fitted to the water inlet, and the water inlet is fitted to a hole portion formed in the filter housing together with the seal ring.

By fitting the water inlet formed in the flushing member housing together with the seal ring fitted over the water inlet in the hole formed in the filter housing, the flushing member can be easily positioned and attached to the filter housing while sufficiently sealing the filter duct.

The present utility model provides a drum-type laundry treating apparatus comprising: a housing; an outer groove supported within the housing; a drum having a bottomed cylindrical shape with one end opened, rotatably installed in the outer tub, for receiving laundry; a drying device for drying the laundry in the drum using heated air; the air filter comprises a filter assembly, a drying device and a fan, wherein the drying device is provided with the fan, the fan is used for enabling air to flow in a filter air channel of the filter assembly, an outer channel air outlet is formed in the outer channel bottom wall of the outer channel, an inlet of the filter air channel is communicated with the outer channel air outlet, and an outlet of the filter air channel is communicated with a drying device air inlet of the drying device.

In the drum type clothes treating apparatus, the filtering assembly can effectively filter the foreign matters such as filings in the air, and prevent the drying capacity from being reduced due to the adhesion of the foreign matters to the internal structure of the drying apparatus. Further, the foreign matter such as lint on the filter screen can be efficiently washed off by the washing member.

Preferably, the outer tank air outlet has a pair of arcuate sides extending along two concentric circles centered on the center of the outer tank bottom wall, respectively, and the filter air duct inlet is formed in a shape corresponding to the outer tank air outlet.

The outer groove air outlet is provided with a pair of arc edges, so that the influence on the annular reinforcing rib which is formed on the outer groove bottom wall and takes the center of the outer groove bottom wall as the center of a circle due to the arrangement of the outer groove air outlet can be reduced as much as possible, and the outer groove bottom wall is favorable for ensuring higher strength.

Preferably, the outlet of the filtering air duct is connected with the drying device through a corrugated pipe.

The filtering air duct outlet is connected with the drying device by the corrugated pipe, so that the vibration of the outer groove is prevented from being transmitted to the drying device by the filtering component by the telescopic corrugated pipe.

Preferably, the filter screen extends along a plane parallel to the outer tank bottom wall.

The filter screen extends along the plane parallel to the bottom wall of the outer tank, so that the filter screen with a larger filter area is arranged, and the filtering capacity of the filtering device can be improved.

Detailed Description

Next, a specific embodiment of the present utility model will be described with reference to the drawings.

The drum-type laundry treatment apparatus according to the present utility model will be described below by taking a washing and drying integrated machine having both a washing function and a drying function as an example. It will be understood by those skilled in the art that the drum-type laundry treating apparatus of the present utility model may be a dryer having only a drying function.

As shown in fig. 1, the drum-type laundry treating apparatus 10 includes: a housing (not shown); an outer groove 11 supported in the housing; a drum 12 rotatably installed in the outer tub 11 for receiving laundry; a drying device 13 for drying the laundry in the drum 12 using the heated air; and a filter unit 1 for filtering foreign matters such as lint in the drying air. For convenience of explanation, the front-rear direction, the up-down direction, and the left-right direction are defined in fig. 1, and the first direction corresponding to the front-rear direction, the second direction corresponding to the up-down direction, and the third direction corresponding to the left-right direction are defined in the following drawings. It will be appreciated by those skilled in the art that the directions specified herein are not intended to limit the actual arrangement of the laundry treating apparatus 10.

As shown in fig. 1, the outer tub 11 has a bottomed cylindrical shape having a laundry inlet 113 at one end. The outer tub 11 is mounted in the housing with the laundry inlet 113 facing forward, and is elastically supported by a lower damper (not shown) and an upper suspension spring (not shown), thereby preventing transmission of vibration of the outer tub 11 to the housing. As shown in fig. 1 to 3, the outer tank 11 has a cylindrical outer tank peripheral side wall 112 and a plate-like outer tank bottom wall 110, and a reinforcing rib 114 protruding rearward for improving the strength of the outer tank bottom wall 110 is provided on the outer surface of the outer tank bottom wall 110, and the reinforcing rib 114 includes an annular rib extending in the circumferential direction and a radial rib extending in the radial direction, and the annular rib and the radial rib intersect with each other.

As shown in fig. 1, the drum 12 has a bottomed cylindrical shape with one end opened, and accommodates laundry. The drum 12 is mounted in the outer tub 11 so as to open toward the laundry inlet 113 of the outer tub 11. A plurality of fine holes may be formed in the wall portion on the outer circumferential side and the wall portion on the bottom side of the drum 12, whereby the washing water and the heated air generated by the drying device 13 can flow between the outer tub 11 and the drum 12. The drum 12 is driven by a motor, not shown, and is rotatable about a rotation axis extending in the horizontal direction. The rotation direction of the drum 12 may be clockwise, counterclockwise, or may be continuously switched between the clockwise and counterclockwise directions when viewed from the front in fig. 1. The rotation axis of the drum 12 may be inclined upward toward the laundry inlet 113.

As shown in fig. 1, a drying device 13 having an integral structure is disposed above the outer tub 11, and the drying device 13 is configured to dry laundry in the drum 12 by using heated air. As shown in fig. 4, the drying device 13 includes: a drying device housing 130 having an air inlet 131 and an air outlet 132, the air inlet 131 and the air outlet 132 being respectively communicated with the inner cavity of the drum 12; an evaporator, not shown, for example, a microchannel evaporator, disposed in the drying device case 130, for dehumidifying the air guided from the drum 12; a condenser, not shown, for example, a microchannel condenser, which is disposed in the drying device case 130 at a position downstream of the evaporator in the air flow direction, and heats the air passing through the evaporator; and a blower 80 for flowing air so as to guide the air in the drum 12 into the drying device case 130 through the air inlet 131 and guide the air passing through the evaporator and the condenser into the drum 12. The drying device 13 further includes a compressor, not shown, for compressing the refrigerant flowing through the evaporator and the condenser.

As shown in fig. 1 to 4, the air inlet 131 of the drying device 13 communicates with the filter tunnel outlet 4 (see fig. 5A) of the filter assembly 1 via the bellows 9 that can be extended and contracted, and the filter assembly 1 is mounted with respect to the outer tub 11 such that the filter tunnel inlet 3 communicates with the outer tub air outlet 111 provided at the outer tub bottom wall 110 of the outer tub 11. Thereby, the vibration of the outer tub 11 can be prevented from being transmitted to the drying device 13 via the filter assembly 1 by the bellows 9. The air outlet 132 of the drying device 13 communicates with the inside of the outer tub 11 at the front end side (i.e., the laundry inlet 113 side) of the outer peripheral surface of the outer tub 11. In the present embodiment, by communicating the air outlet 132 with the front end side of the outer peripheral surface of the outer tub 11, the air heated by the drying device 13 can be directly supplied into the drum 12, and the air is not dispersed by the pores of the drum 12, as compared with the case where the air outlet 132 is communicated with the rear end side of the outer peripheral surface of the outer tub 11, and the laundry in the drum 12 can be dried more efficiently.

As shown in fig. 5A to 8, the filter assembly 1 includes a filter housing 2 and a filter device 5, the filter housing 2 includes a first filter housing 201 and a second filter housing 202, and a filter air duct is formed inside by combining the first filter housing 201 and the second filter housing 202. As means for combining the first filter housing 201 and the second filter housing 202, screw fastening, welding, or the like can be cited. The first filter housing 201 has a filter duct inlet 3 through which air flows into the filter duct, a filter duct outlet 4 through which air flows out of the filter duct, and a filter device mounting portion 8 to which the filter device 5 is locked. The opening area of the filter duct inlet 3 is preferably larger than the opening area of the filter duct outlet 4, and the opening area of the filter duct inlet 3 is preferably 1.5 times or more the opening area of the filter duct outlet 4, but the present utility model is not limited thereto. As an example, the opening area of the filter tunnel inlet 3 is 7000mm ² The opening area of the outlet 4 of the filtering air duct is 4000mm ² . The filter housing 2 is not limited to the first filter housing 201 and the second filter housing 202, and may be an integrally molded housing, or may be a combination of three or more housings. In the case where the filter housing 2 is of an integrally formed structure, an opening may be provided at a proper position of the filter housing 2 to ensure an operation space required when the filter device 5 is mounted into the filter housing 2. After the filter device 5 is mounted, the opening is closed.

As shown in fig. 1 and 5A, the filter air duct outlet 4 is arranged radially outside the outer-tank peripheral side wall 112 of the outer tank 11, and a portion of the first filter housing 201 facing the outer-tank peripheral side wall 112 of the outer tank 11 is configured as a first wall portion 203, and the first wall portion 203 is formed into an arc-shaped surface corresponding to the outer-tank peripheral side wall 112 of the outer tank 11. The first filter housing 201 has a planar second wall portion 204 facing the first wall portion 203 through the filter duct, and an inner side surface of a transition portion 205 between the first wall portion 203 and the second wall portion 204 smoothly extends toward an inner peripheral surface of the filter duct outlet 4, thereby smoothly guiding air toward the filter duct outlet 4. The second wall 204 is not limited to a planar shape, and may be curved with an appropriate curvature. The shape of the second wall portion 204 is not limited as long as the air can be smoothly guided toward the filter stack outlet 4 by providing the transition portion 205.

As shown in fig. 3 and 5A, the outer tank air outlet 111 is provided on the outer surface of the outer tank bottom wall 110 of the outer tank 11, and has a pair of arcuate sides 111A, 111B extending along two concentric circles around the center of the outer tank bottom wall 110 of the outer tank 11, respectively, and the filter air duct inlet 3 is formed in a shape corresponding to the outer tank air outlet 111. The shape of the outer tank air outlet 111 is not limited as long as it can simultaneously ensure sufficient strength of the outer tank bottom wall 110 and a sufficient opening area of the filter air duct inlet 3, and may be any shape other than the shape having the pair of arcuate sides 111A, 111B.

As shown in fig. 2 and 7 to 8, the filter device 5 is provided in the filter duct, and includes a filter screen 51 for filtering foreign matters such as lint in the air flowing in the filter duct. In the case of the filter assembly 1 being mounted with respect to the outer tank 11, the filter screen 51 extends along a plane parallel to the outer tank bottom wall 110 of the outer tank 11. The filter mesh 51 may of course also extend along a plane inclined at a suitable angle with respect to the outer tank bottom wall 110 of the outer tank 11, but is preferably parallel to the outer tank bottom wall 110 of the outer tank 11. The filter device 5 further includes a filter frame 52, the filter screen 51 is fixed to the filter frame 52, the filter frame 52 includes a positioning rib 521 protruding toward the air outlet surface side of the filter screen 51 (i.e., the side facing the filter duct outlet 4 in fig. 7) in the first direction which is the opening direction of the filter duct inlet 3, and the protruding height of the positioning rib 521 in the first direction is 8mm or more, and more preferably 13mm or more. The upper limit of the protruding height of the positioning rib 521 in the first direction is not limited, and may be appropriately set according to the actual mounting demand. At least one protrusion 503 protruding from the filter frame 52 in the second direction is provided on one side end surface and the other side end surface of the filter frame 52, and the protrusion 503 has an inclined guide surface 501 for guiding the attachment of the filter device 5 and a positioning surface 502 for positioning the filter device 5 in the second direction. In fig. 8, only three protrusions 503 are shown provided on one end surface of the filter frame 52 in the second direction, but the protrusions 503 may be provided on the other end surface of the filter frame 52 in the second direction. At least one protrusion 503 may be provided on at least one of the one end surface and the other end surface of the filter frame 52 in the second direction. The positioning rib 521 and the protrusion 503 are positioned and locked in the filter device mounting portion 8, whereby the filter device 5 is mounted at a predetermined position. The filter device 5 may be attached to the filter device attachment portion 8 by other means than locking, for example, by screw fastening.

As shown in fig. 7, the filter tunnel inlet 3 and the filter mesh 51 are completely offset in a second direction orthogonal to the first direction and being the opening direction of the filter tunnel outlet 4 when viewed in the first direction. The second filter housing 202 has opposite side walls 21 opposite both the windward side of the filter mesh 51 and the filter tunnel inlet 3 in the first direction. In the opposite side wall 21, a first portion 211 opposite to the filter tunnel inlet 3 protrudes in a first direction away from the filter tunnel inlet 3 with respect to a second portion 213 opposite to the windward side of the filter mesh 51. As an example, when the protruding height of the positioning rib 521 in the first direction is about 13mm, the distance from the first portion 211 to the windward side of the filter mesh 51 in the first direction is about 46mm, and the distance from the second portion 213 to the windward side of the filter mesh 51 in the first direction is about 30 mm. The first portion 211 and the second portion 213 are smoothly connected to each other. The average size of the first sites 211 is smaller than the average size of the second sites 213 in a third direction orthogonal to both the first and second directions. That is, in the third direction, the first portion 211 is entirely narrower than the second portion 213. In addition, the relationship between the first direction and the third direction is not limited to being orthogonal to each other, and for example, the second direction may intersect at an angle other than 90 ° with respect to the first direction, and the third direction may intersect at an angle other than 90 ° with respect to the first direction and the second direction.

As shown in fig. 7, an air guide surface 22 is formed on an inner surface of the first filter housing 201 opposite to the opposite side wall 21. The air guide surface 22 extends smoothly from the filter duct inlet 3 toward the windward side of the filter screen 51 in the direction in which the air flows in the filter duct, for guiding the air flowing in from the filter duct inlet 3 toward the windward side of the filter screen 51.

The inventors of the present utility model have found through intensive studies and trial and error that the screen area of a filter unit in which a conventional screen is disposed in the horizontal direction as in patent document 1 is 4300mm ² The wind loss is 1029Pa, and the area of the filter screen of the filter assembly which is arranged along the plane parallel to the bottom wall 110 of the outer groove 11 reaches 12000mm ² The wind loss is about 2.8 times of that of the existing filter assembly, is 850Pa, and is about 83% of that of the existing filter assembly. That is, the filter assembly of the present utility model can greatly increase the area of the filter screen and reduce the wind loss as compared with the conventional filter assembly.

In addition, according to the present utility model, since the first portion 211 protrudes in the first direction away from the filter duct inlet 3 with respect to the second portion 213, the wind loss can be significantly reduced as compared with a structure in which the first portion 211 and the second portion 213 are aligned in the first direction. Specific test data are as follows.

From the test data, the filter assembly of the utility model can reduce the wind loss by about half, and has remarkable effect of reducing the wind loss.

In addition, as shown in fig. 8, the filter assembly 1 of the present utility model may further include a flushing member 100. As shown in fig. 9 to 11, the flushing member 100 includes a flushing member housing 200, and the flushing member housing 200 is formed as a part of the filter frame 52. A water inlet 210 is formed at the rinsing member housing 200, the water inlet 210 for introducing rinsing water into an inner chamber of the rinsing member housing 200. The interior chamber comprises a first chamber 101, a second chamber 102 and a third chamber 103. The first chamber 101 communicates with the water inlet 210 and has a first water outlet A1 for discharging wash water from the first chamber 101 to the second chamber 102. The second chamber 102 has a second water outlet A2 for discharging the washing water from the second chamber 102 to the third chamber 103. The third chamber 103 has a third water outlet A3 for discharging the washing water toward the washing target such as the filter screen. The flushing member 100 is attached to the filter frame 52 so as to flush the windward side of the filter mesh 51 from above by flushing water discharged from the third water outlet A3. At this time, the protrusion 503 is provided on the flushing member housing 200 and thus on one end surface of the filter frame 52 in the second direction.

As shown in fig. 10, the flush member housing 200 includes a top wall 220, a bottom wall 230, and side walls 240 that form an interior chamber. As shown in fig. 8 and 9, the flushing member case 200 is provided with a water inlet nozzle 7 protruding, the water inlet nozzle 7 is provided with a water inlet 210, a seal ring may be fitted around the water inlet nozzle 7, and the water inlet nozzle 7 is fitted into a hole 219 formed in the filter case 2 together with the seal ring. The flushing member housing 200 is not limited to an integral structure, and may be formed by combining a plurality of flushing member housings. For example, the washing member housing 200 may include a first washing member housing constituting an upper half of the washing member housing 200 and a second washing member housing constituting a lower half of the washing member housing 200, and the water inlet 210 is formed at the first washing member housing, thereby forming the inner chamber by combining the first washing member housing and the second washing member housing together. As means for combining the first flushing member housing and the second flushing member housing, screw fastening, welding, or the like may be mentioned.

In fig. 11, the first water outlet A1 is shown to include a plurality of first water outlet holes uniformly arranged along the extending direction of the inner chamber, but may be configured to include continuous elongated holes extending along the extending direction of the inner chamber. In order to ensure uniform discharge of the washing water to the washing target, the first water outlet A1 preferably includes a plurality of first water outlet holes uniformly arranged along the extending direction of the inner chamber. Regardless of the configuration and arrangement of the first water outlet A1, it is preferable that the opening area of the first water outlet A1 is smaller than the opening area of the water inlet 210. In the case where the first water outlet A1 includes a plurality of first water outlet holes, the opening area of the first water outlet A1 is a sum of the opening areas of the respective plurality of first water outlet holes.

The second water outlet A2 may include a continuous elongated hole extending along the extending direction of the inner chamber. In the present embodiment, the second water outlet A2 is formed by an elongated gap extending in the extending direction of the inner chamber, which is formed between the rib 6 protruding from the top wall 220 toward the bottom wall 230 and extending in the extending direction of the inner chamber, and the bottom wall 230. The position of the upper end edge in the height direction of the second water outlet A2 (i.e., the position of the lower end edge of the bead 6) is below the center position in the height direction of the first water outlet A1. Accordingly, the portion of the water flow flowing out of the first water outlet A1, which is more likely to form the water spray, is blocked by the rib 6, so that the water flow flowing out of the second water outlet A2 is ensured to be more stable, and the flushing water discharged to the flushing object is more uniform. The form and the formation of the second water outlet A2 are not limited as long as the flush water can be ensured to be more uniform. The opening area of the second water outlet A2 is not limited.

In fig. 11, the third water outlet A3 is shown to include a plurality of third water outlet holes uniformly arranged along the extending direction of the inner chamber, but may be provided to include continuous elongated holes extending along the extending direction of the inner chamber. In view of ensuring uniform discharge of the washing water to the washing target and ensuring strength of the wall portion forming the third water outlet A3, it is preferable that the third water outlet A3 includes a plurality of third water outlet holes uniformly arranged along the extending direction of the inner chamber. The opening area of the third water outlet A3 is smaller than that of the first water outlet A1.
