Description

Technical Field

[0001] The present invention relates to the technical field of household appliance fittings, and particularly to a box sub-assembly for a condensing dryer. Background Art

[0002] A dryer is a common household appliance that uses electric heating to instantly evaporate and dry the moisture in washed clothes. The main principle is to place the clothes in a rolling barrel body and dry the clothes through hot air. The hot water vapor is condensed into water at the condensation device at the air outlet and discharged through a pipeline.

[0003] The existing one, such as the Chinese patent publication number "CN110753767B", the name of the patent is "Condensing Dryer", and the patent includes "a condensing dryer with a steam generator, especially relating to the automatic water injection of the water tank of the steam generator. The condensate tank is arranged in a container, and the container is fluidly connected to the water container of the steam generator via a discharge pipeline. Wherein, near the condensate tank, a branch element is connected to the pipeline for transporting condensate from a pump to the condensate tank".

[0004] Since lint is usually generated after clothes are washed, and due to actions such as the blowing of the circulating air, the lint will separate from the clothes. In order to prevent the lint from precipitating at the condenser along with the moisture in the circulating air, the existing common treatment method is to add a filter net structure on the air duct between the rolling barrel and the condenser, so as to achieve the purpose of preventing lint from adhering to the condenser. However, the disadvantage of this method is that although a cleaning alarm is set on the existing filter net mechanism to prompt the user to clean regularly, before the cleaning alarm upper limit is triggered, there is already some lint on the filter net, which will still hinder the normal flow of the circulating air, thereby reducing the drying efficiency and increasing the drying energy consumption.

[0033] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Please refer to Figures 1-9 , a box body assembly for a condensation clothes dryer provided by an embodiment of the present invention includes an air flow channel 3 located between a barrel body 1 and an isolation box 2, and a filtering mechanism is provided on the air flow channel 3. The filtering mechanism includes:

[0035] A sleeve box assembly 4, which includes an outer sleeve box 4.1 fixedly inserted into the isolation box 2. The upper end of the outer sleeve box 4.1 extends into the air flow channel 3, and a vent 4.2 communicating with the isolation box 2 is provided on the outer sleeve box 4.1;

[0036] A filter guide assembly 5, which includes an inner built-in frame 5.1 adaptively inserted into the outer sleeve box 4.1. A filter cartridge unit 5.2 is rotatably installed on the inner built-in frame 5.1, and the end of the filter cartridge unit 5.2 is communicated with the air flow channel 3 through an air guide pipe unit 5.3;

[0037] A cleaning brush assembly 6, which includes a cleaning brush unit 6.1 extending into the filter cartridge unit 5.2. The cleaning brush unit 6.1 can move relative to the inner wall of the filter cartridge unit 5.2 to scrape off lint;

[0038] Specifically, the barrel body 1 is the drum of an existing dryer, the isolation box 2 is the box body for accommodating the condenser. When the dryer barrel cover at the end of the barrel body 1 is closed, the air flow inside the barrel body 1 can pass through the air flow channel 3 and then through the condenser inside the isolation box 2. The sleeve box assembly 4 is located inside the air flow channel 3. The box body of the outer sleeve box 4.1 blocks the air flow channel 3. A ventilation opening 4.2 communicating with the isolation box 2 is provided on the outer sleeve box 4.1, so that the air flow flowing out of the barrel body 1 enters the outer sleeve box 4.1 and then enters the isolation box 2 through the ventilation opening 4.2;

[0039] The filter cartridge unit 5.2 filters the lint mixed in the air flow entering the outer sleeve box 4.1. Specifically, the air flow enters the inside of the cylinder body from the cylinder opening of the filter cartridge unit, and then passes through the filter screen part of the filter cartridge unit, so that the lint is intercepted inside the filter cartridge unit. The cleaning assembly 6 extends into the cleaning unit 6.1 inside the filter cartridge unit 5.2. The cleaning unit 6.1 is in contact with the inner wall of the filter cartridge unit 5.2. When the cleaning unit 6.1 moves relatively inside the filter cartridge unit 5.2, it can clean the lint on the inner wall of the filter cartridge unit 5.2, thus keeping the filter cartridge unit 5.2 unobstructed;

[0040] Therefore, by setting the sleeve box assembly that reconstructs the air flow channel, the guiding and filtering assembly that intercepts lint, and the cleaning unit that keeps the air flow of the filter cartridge unit unobstructed, before triggering the upper limit of the cleaning alarm, the lint on the filter cartridge unit has been cleaned multiple times, improving the cleaning frequency, thus keeping the air flow of the filter cartridge unit unobstructed, which is beneficial to increasing the drying efficiency and has the effect of reducing energy consumption.

[0041] In another embodiment provided by the present invention, the upper end of the outer sleeve box 4.1 is an open end. A sealing cover plate 4.3 is provided at the upper end of the outer sleeve box 4.1. The sealing cover plate 4.3 is fixed to the built-in frame 5.1. The sealing cover plate 4.3 can completely block the open end of the outer sleeve box 4.1. A rubber pad is fixed on the surface of the sealing cover plate 4.3 in contact with the open end, so as to improve the sealing performance when the sealing cover plate 4.3 blocks the open end of the outer sleeve box 4.1.

[0042] In another embodiment provided by the present invention, the number of the filter cartridge units 5.2 can be selected to be multiple. The filter cartridge unit 5.2 includes a pipe body 5.21, and a plurality of long strip openings 5.22 are formed on the side surface of the pipe body 5.21. A filter screen 5.23 that covers each long strip opening 5.22 is fixed to the inner wall of the pipe body 5.21. The length direction line of the pipe body 5.21 is parallel to the horizontal plane. Further, the built-in frame 5.1 is a frame-shaped frame, and a plurality of support plates 5.4 are fixed inside the frame of the built-in frame 5.1. A through opening 5.5 for the pipe body 5.21 to pass through is formed on the support plate 5.4. The support plate 5.4 plays a supporting role in keeping the pipe body 5.21 in a horizontal state. Preferably, an annular groove 5.6 is formed on the outer circumference of the pipe body 5.21, and a plurality of support wheels 5.7 fixed to the through opening 5.5 are evenly distributed in the circumferential direction of the annular groove 5.6, so as to limit the axial movement of the pipe body 5.21 and at the same time reduce the resistance when the pipe body 5.21 rotates axially;

[0043] Further, the air guide pipe unit 5.3 includes a bent pipe 5.31 whose tail end is rotatably inserted into the pipe body 5.21. The head end of the bent pipe 5.31 extends out of the upper end of the outer casing 4.1 and is communicated with the air flow channel 3, so as to receive the air flow flowing out from the direction of the barrel body 1. The bent pipe 5.31 guides the air flow into the pipe body 5.21, and then the air flow passes through the long strip openings 5.22 and enters the outer casing 4.1, and then enters the isolation box 2 through the ventilation opening 4.2. During this process, the filter screen 5.23 retains the lint in the air flow in the pipe body 5.21, so as to achieve the filtering effect.

[0044] In another embodiment provided by the present invention, a sealing baffle 5.32 is fixed to the tail end of the bent pipe 5.31, and an extension pipe 5.33 is fixedly penetrated through the sealing baffle 5.32. The extension pipe 5.33 is located inside the pipe body 5.21. A plurality of air flow openings 5.34 are formed on the pipe body of the extension pipe 5.33. The length direction line of the extension pipe 5.33 is parallel to the length direction line of the pipe body 5.21. Preferably, the cross section of the extension pipe 5.33 is semi-circular, such as D-shaped. Each air flow opening 5.34 is located on the flat part of the pipe body of the extension pipe 5.33. The flat part of the pipe body of the extension pipe 5.33 is parallel to the horizontal plane, and the flat part direction of the extension pipe 5.33 faces downward. During use, the air flow in the bent pipe 5.31 enters the extension pipe 5.33, and then is evenly blown into the pipe body 5.21 through each air flow opening 5.34;

[0045] It should be further noted that the diameter values of each air flow opening 5.34 gradually increase along the flowing direction of the air flow in the extension pipe 5.33, so as to achieve the effect of evenly dividing the air flow.

[0046] In yet another embodiment provided by the present invention, the cleaning unit 6.1 includes a long strip frame 6.11. The long strip frame 6.11 is located directly below the extension pipe 5.33. The frame opening surface of the long strip frame 6.11 is parallel to the flat surface part of the extension pipe 5.33. A clamping groove 6.12 is formed on the side surface of the long strip frame 6.11. A brush strip 6.13 is fitted and clamped in the clamping groove 6.12. The length direction of the brush strip 6.13 is the same as the length direction of the long strip frame 6.11. During actual use, the brush strip 6.13 is disassembled and assembled in the clamping groove 6.12, so as to realize the replacement of the brush strip 6.13. In addition, the long strip frame 6.11 is positioned in the pipe body 5.21 through the support of the support assembly 6.2;

[0047] Among them, the support assembly 6.2 includes a supporting block 6.21 fixed to the sealing baffle 5.32 and a side plate 6.22 fixed to the end of the long strip frame 6.11. The supporting block 6.21 is located inside the pipe body 5.21. The supporting block 6.21 can provide a supporting force for the long strip frame 6.11 inside the pipe body 5.21. The side plate 6.22 is connected to the built-in frame 5.1 through a locking pin mechanism 7. The supporting block 6.21 and the side plate 6.22 provide a supporting force for the long strip frame 6.11 in the pipe body 5.21;

[0048] Among them, the locking pin mechanism 7 includes a long strip block 7.3 fixed to the bottom end of the built-in frame 5.1. A pin hole 7.1 is formed at the end of the long strip block 7.3. The cross-section of the orifice of the pin hole 7.1 is rectangular. A pin rod 7.2 is fitted and inserted in the pin hole 7.1. The cross-section of the pin rod 7.2 is a rectangular surface adapted to the orifice of the pin hole 7.1. One end of the pin rod 7.2 is fixed to the side plate 6.22. A first insertion hole 7.4 is formed at the bottom of the long strip block 7.3. A second insertion hole 7.5 is formed on the rod body of the pin rod 7.2. A vertical insertion rod 7.6 is fixed to the inner bottom of the outer sleeve box 4.1;

[0049] During actual use, when the pin rod 7.2 is completely inserted into the pin hole 7.1, at this time, the first insertion hole 7.4 is aligned with the second insertion hole 7.5. When the built-in frame 5.1 is placed into the outer sleeve box 4.1, at this time, the vertical insertion rod 7.6 passes through the first insertion hole 7.4 and the second insertion hole 7.5 at the same time, so as to limit the pin rod 7.2 in the pin hole 7.1, and a locking connection is formed between the side plate 6.22 and the built-in frame 5.1.

[0050] In yet another embodiment provided by the present invention, a mesh hole groove 6.14 is fixed to the bottom of the frame of the long strip frame 6.11. The mesh hole groove 6.14 is a porous groove body composed of a hard metal mesh. The cross-section of the mesh hole groove 6.14 is a semi-circular structure in the shape of a D. An installation rod 6.15 is fixed to the long strip frame 6.11. The installation rod 6.15 is located in the middle of the long strip frame 6.11. The length direction line of the installation rod 6.15 is parallel to the length direction line of the long strip frame 6.11. The length direction line of the installation rod 6.15 and the frame opening surface of the long strip frame 6.11 are on the same horizontal plane. A net plate 6.16 that automatically droops is movably hinged to the installation rod 6.15. The net plate 6.16 can rotate axially around the installation rod 6.15. The net plate 6.16 can be selected as a plastic net plate, a light metal net plate, etc. The net plate 6.16 divides the groove space of the mesh hole groove 6.14 into a first region and a second region. The net plate 6.16 is located in the middle of the installation rod 6.15. The length direction line of the net plate 6.16 is parallel to the length direction line of the installation rod 6.15. A cleaning strip 6.17 that contacts the inner bottom wall of the mesh hole groove 6.14 is installed at the bottom end of the net plate 6.16. It should be further noted that there is a spaced space between the long strip frame 6.11 and the extension pipe 5.33;

[0051] During actual use, the air flow blown out by the extension pipe 5.33 enters the first region of the mesh hole groove 6.14. At this time, the mesh hole groove 6.14, the net plate 6.16, and the filter net 5.23 can all perform lint filtering on the air flow. For example, after part of the air flow is filtered by the mesh hole groove 6.14 and then filtered by the filter net 5.23, or the air flow is filtered by the net plate 6.16 and then filtered by the filter net 5.23, or after part of the air flow is filtered by the net plate 6.16, the air flow is then filtered by the mesh hole groove 6.14 and then filtered by the filter net 5.23, so as to achieve the effect of superimposed filtering with at least two filtrations.

[0052] Further, during the filtering process, as the lint increases, when the first region of the groove space of the net plate 6.16 and the mesh hole groove 6.14 is covered and blocked by lint, at this time, the net plate 6.16 deflects towards the second region under the blowing action of the air flow, thereby expanding the inner wall surface of the first region. At the same time, under the action of the self-gravity of the net plate 6.16, the net plate 6.16 has a tendency to return to the drooping state. Therefore, the net plate 6.16 will exhibit a certain swaying state. At this time, the cleaning strip 6.17 sweeps the bottom of the mesh hole groove 6.14 along with the swing of the net plate 6.16, so as to keep the air flow in the first region unobstructed and achieve a certain self-cleaning filtering effect;

[0053] Furthermore, when the lint volume further increases and the mesh plate 6.16 cannot swing, at this time, the air flow passes through the interval space between the long strip frame 6.11 and the extension pipe 5.33, and then passes through the filter net 5.23 for filtration, achieving the effect of shunt filtration; during the whole process, the air flow is superimposed filtered and self-cleaned filtered. When the whole filtration reaches saturation, the air flow is automatically shunt filtered again, always keeping the air flow in a smooth state during the filtration process and improving the effect of lint filtration.

[0054] In another embodiment provided by the present invention, a driving mechanism 8 is arranged inside the built-in frame 5.1. The driving mechanism 8 can drive the tube body 5.21 to rotate axially. When the tube body 5.21 rotates, at this time, the filter net 5.23 and the brush strip 6.13 move relatively, so as to scrape the lint attached to the filter net 5.23. Since the rotation of the tube body 5.21 relative to the movement of the brush strip 6.13 is clockwise rotation, the scraped lint accumulates above the brush strip 6.13. As the accumulation amount increases, it collapses into the internal of the mesh hole groove 6.14 fixed to the long strip frame 6.11, realizing the concentration of lint, facilitating subsequent cleaning, and at the same time keeping the filter net 5.23 in a smooth state.

[0055] Specifically, the driving mechanism 8 includes a one-way ratchet 8.1 fixedly sleeved on the tube body 5.21. A rack 8.2 is adaptively meshed with the one-way ratchet 8.1. The rack 8.2 is an arc rack, and the center of the circle of the rack 8.2 overlaps with the center of the movement of the bucket cover 10 of the barrel body 1 deflecting. The rack 8.2 movably penetrates through one side of the outer sleeve box 4.1. One end of the rack 8.2 is fixed to the bucket cover 10 of the barrel body 1, and a rubber sealing ring 8.3 is fixedly sleeved on the rack 8.2.

[0056] In actual use, the bucket cover 10 on the body of the dryer is hinged to the body 11 of the dryer, and the bucket cover 10 is opened and closed in a flat door state on the body 11 of the dryer. When the bucket cover 10 covers the barrel body 1, at this time, the rack 8.2 is in a state of being inserted into the outer sleeve box 4.1. At this time, the one-way ratchet 8.1 drives the tube body 5.21 to rotate, so as to realize the relative movement between the filter net 5.23 and the brush strip 6.13. When the bucket cover 10 cancels covering the barrel body 1, at this time, the rack 8.2 is in a state of being drawn out from the outer sleeve box 4.1. At this time, the one-way ratchet 8.1 cannot drive the tube body 5.21 to rotate, and the tube body 5.21 is in a static state. In other words, every time the bucket cover 10 is opened, the tank body 5.21 rotates once, so that a reasonable cleaning frequency is maintained between the filter net 5.23 and the brush strip 6.13, which is beneficial to avoiding excessive cleaning between the filter net 5.23 and the brush strip 6.13 and extending the service life.

[0057] In another embodiment provided by the present invention, the filter cartridge unit 5.2 can be selected as multiple groups. Tooth rings 12 are fixedly sleeved on the tube bodies 5.21 of each group of filter cartridge units 5.2. A plurality of tooth columns 13 are rotatably installed on the support plate 5.4. Each tooth column 13 is located between the respective tube bodies 5.21. The tooth column 13 meshes with the adjacent tooth rings 12 on both sides, so that the rotation directions between the respective tube bodies 5.21 are kept consistent, thereby increasing the filtration area.

[0058] In another embodiment provided by the present invention, a blocking unit 9 capable of blocking the end of the tube body 5.21 is fixed on the side plate 6.22. The blocking unit 9 includes an annular groove 14 opened at the end of the tube body 5.21. A bearing ring 15 is fixedly embedded in the ring body of the annular groove 14. A tapered plug 16 is inserted into the inner ring of the bearing ring 15. The tapered surface of the tapered plug 16 contacts the inner wall of the bearing ring 15. The end of the tapered plug 16 is fixed to the side plate 6.22. During actual use, when a locking connection is formed between the side plate 6.22 and the built-in frame 5.1, at this time, the tapered plug 16 blocks the end of the tube body 5.21, thereby preventing the air flow in the tube body 5.21 from flowing out of the tube orifice, and at the same time ensuring that the tube body 5.21 can rotate normally.

[0059] In another embodiment provided by the present invention, a protruding column 17 is fixed on the side surface of the tapered plug 16. A sleeve ring 18 fixed to the end of the extension tube 5.33 is inserted outside the protruding column 17. The protruding column 17 and the sleeve ring 18 can be inserted and pulled out. When the protruding column 17 is inserted into the sleeve ring 18, the protruding column 17 provides a supporting force for the extension tube 5.33.

[0060] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
