Description

Technical Field

[0001] This invention belongs to the technical field of clothing processing equipment, specifically, it relates to an additive dispensing device with an air duct, and particularly to clothing processing equipment having the additive dispensing device. Background Technology

[0002] The additive dispensing device includes a water storage box and a dispensing box that can be pulled out and installed inside the water storage box. The bottom of the water storage box is provided with a drain port that communicates with the clothes treatment drum. The dispensing box has at least one dispensing chamber. The user puts the additives required for the washing and care process into the dispensing chamber. During the washing and care process, the additives in the dispensing chamber are flushed into the water storage box by rinsing water, and then flow into the clothes treatment drum through the drain port.

[0003] Because clothing is frequently in contact with the outside world, microorganisms adhere to it. During the washing and care process, these microorganisms remain inside the garment processing drum. At the same time, due to the prolonged flow of washing water, a large amount of dirt and bacteria accumulate on the outside of the garment processing drum. After the washing and care program ends, a large amount of moisture remains inside the garment processing drum, which allows microorganisms to grow and produces odors. Especially after the user opens the door of the garment processing equipment, the odors remaining inside the machine spread outwards, causing discomfort to the user and affecting the user experience.

[0004] When the door of the garment processing equipment is closed, the dispensing chamber of the additive dispensing device is connected to the outside atmosphere. How to set up an additive dispensing device to allow gas exchange between the inside of the garment processing drum and the outside atmosphere, thereby removing odor substances from the inside of the garment processing drum, has become an urgent problem to be solved.

[0005] In view of this, the present invention is hereby proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an additive dispensing device to achieve the purpose of gas exchange between the additive dispensing device and the outside.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0009] Furthermore, the air duct has an air inlet that communicates with the outside of the water storage box, the bottom of the water storage box has a through hole, the air inlet of the air duct communicates with the inside of the water storage box through the through hole, and the side wall of the water storage box has an air outlet that communicates with the inside of the water storage box.

[0010] Furthermore, the bottom of the water storage box is provided with a cover, and the inside of the cover forms a receiving cavity with an opening at the top. The water storage box and the cover are matched to close the opening of the receiving cavity to form an air duct. One end of the cover is provided with an air inlet for the air duct.

[0011] Furthermore, the receiving cavity is an inverted cone or inverted frustum shape with a radial dimension that gradually narrows from top to bottom, and the lowest point of the inverted cone or inverted frustum shape is provided with an air inlet for the air duct.

[0012] Furthermore, the bottom wall of the receiving cavity is recessed downward on the side near the air inlet of the air duct to form a guide groove. The guide groove has a guide wall that is arranged opposite to the air inlet of the air duct, and the guide wall extends upward at an angle away from the air inlet of the air duct.

[0013] Furthermore, the interior of the water storage box is provided with an upwardly protruding boss, and a portion of the top of the boss is recessed downward to form a drainage groove. An air outlet is provided on the side wall of the water storage box, and a drainage hole communicating with the air outlet is provided on the side wall of the drainage groove.

[0014] Furthermore, the drainage channel is a molded channel with a notch, and the air duct is connected to the drainage channel through the notch. The notch and the drainage hole are set opposite to each other at both ends of the drainage channel, and the bottom of the drainage channel is an upwardly sloping surface.

[0015] Furthermore, a filter is installed inside the drainage channel, and the filter is detachably installed on the side wall of the drainage channel via a rotating shaft structure.

[0016] Furthermore, the filter includes a filter frame and a filter screen installed on the filter frame. The two ends of the filter frame are respectively attached to the side walls of the flow channel on the opposite side, and the bottom end of the filter frame is attached to the bottom of the flow channel.

[0017] Another object of the present invention is to provide a garment processing device to achieve gas exchange between the inside of the garment processing drum and the outside atmosphere.

[0018] A garment processing device includes a garment processing drum and an additive dispensing device as described above, wherein one end of an air duct is connected to the interior of the garment processing drum.

[0047] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] like Figure 1 , Figures 9 to 17 As shown, the present invention provides an additive dispensing device, including a hollow water storage box 3. The bottom of the water storage box 3 is provided with an air duct. One end of the air duct is connected to the interior of the water storage box 3, and the other end of the air duct is connected to the exterior of the water storage box 3.

[0049] Through the aforementioned additive dispensing device, external air flows into the air duct through the water storage box 3, and then fresh air is introduced into the interior of the clothing treatment drum through the air duct, or the air inside the clothing treatment drum flows into the water storage box 3 through the air duct, and then the air inside the clothing treatment drum is discharged to the outside, realizing gas exchange between the interior and exterior air of the clothing treatment drum, removing odors inside the clothing treatment drum, and improving the user experience.

[0050] Example 1

[0051] like Figure 9 and Figure 11 As shown, the present invention provides an additive dispensing device. The air duct has an air inlet 42 that communicates with the outside of the water storage box 3. The bottom of the water storage box 3 is provided with a through hole 31. The air inlet 42 of the air duct communicates with the inside of the water storage box 3 through the through hole 31. The side wall of the water storage box 3 is provided with an air outlet 32 ​​that communicates with the inside of the water storage box 3.

[0052] In this embodiment, the air inlet 42 of the air duct is connected to the interior of the dispensing box 1, and the air outlet 32 ​​on the side wall of the water storage box 3 connects the air duct with the outside atmosphere. Thus, the air in the clothing processing drum flows into the air duct through the air inlet 42 and is discharged to the outside through the air outlet 32, thereby realizing the ventilation of the clothing processing drum.

[0053] like Figure 9 and Figure 11As shown, in this embodiment, the bottom of the water storage box 3 is provided with a cover 4, and the inside of the cover 4 is formed with a receiving cavity 41 with an opening at the top. The water storage box 3 and the cover 4 cooperate to close the opening of the receiving cavity 41 to form an air duct. One end of the cover 4 is provided with an air inlet 42 of the air duct.

[0054] In this embodiment, the water storage box 3 and the cover 4 cooperate to close the opening of the receiving cavity 41 to form an air duct, so that the air duct is closed relative to the outside world, avoiding the leakage of air flowing into the air duct and causing the spread of odor substances inside the clothes processing drum, which would affect the user's experience.

[0055] like Figure 15 As shown, in this embodiment, the receiving cavity 41 is an inverted cone or inverted frustum shape with a radial dimension that gradually narrows from top to bottom, and an air inlet 42 for the air duct is provided at the lowest point of the inverted cone or inverted frustum shape.

[0056] In this embodiment, the air inlet 42 of the air duct is located at the lowest point of the inverted cone or inverted frustum shape, which is conducive to the air in the clothing processing drum flowing into the air duct through the air inlet 42 and then flowing upward quickly, and then flowing into the interior of the water storage box 3 through the bottom through hole 31, and finally being discharged into the outside through the air outlet 32 ​​on the side wall of the water storage box 3.

[0057] Preferably, the receiving cavity 41 formed inside the cover 4 is an inverted isosceles triangle that gradually slopes towards the center from the left and right sides. The air inlet 42 is located at the lowest point of the inverted isosceles triangle so that the air flowing into the air duct from the clothes handling tube forms a vortex airflow at the air inlet 42, which is more conducive to the rapid flow of air to the through hole 31 and avoids the gas from accumulating at the bottom of the receiving cavity 41.

[0058] like Figures 15 to 17 As shown, in this embodiment, the bottom wall of the receiving cavity 41 is recessed downward on the side near the air inlet 42 of the air duct to form a guide groove 43. The guide groove 43 has a guide wall 431 that is disposed opposite to the air inlet 42 of the air duct. The guide wall 431 extends upward at an angle away from the air inlet 42 of the air duct.

[0059] In this embodiment, the guide wall 431 of the guide groove 43 extends upward in a direction away from the air inlet 42 of the air duct, that is, the guide wall 431 of the guide groove 43 extends upward in a direction away from the air inlet 42 of the air duct, so that the air inside the clothes processing drum flows upward along the first side of the guide groove 43, avoiding the accumulation of air at the bottom of the air duct, especially the accumulation of odor substances at the bottom of the air duct and the inability to be discharged to the outside.

[0060] In this embodiment, the bottom of the water storage box 3 and the inside of the cover 4 are both formed with openings facing each other. The receiving cavity at the bottom of the water storage box 3 and the receiving cavity 41 inside the cover 4 cooperate to close the opening to form an air duct, thereby increasing the space above the air duct, so that the air inside the clothes processing drum can quickly flow into the air duct and move upward through the through hole 31 at the bottom of the water storage box 3 into the interior of the water storage box 3.

[0061] Alternatively, the inside of the cover 4 has a cavity 41 with an open top. The side of the water storage box 3 facing the cover 4 is flat. The opening end of the cavity 41 inside the cover 4 is bent outward to form a flange. The flange corresponds to and fits against the side of the water storage box 3 facing the cover 4 to close the opening of the cavity 41 and form an air duct. This facilitates the assembly of the water storage box 3 and the cover 4 and ensures the airtightness of the air duct.

[0062] like Figure 9 and Figure 11 As shown, in this embodiment, the air duct extends from the front end of the bottom of the water storage box 3 to the rear end of the bottom of the water storage box 3 to form a long strip-shaped air duct extending along the length of the water storage box 3, so that the gas inside the air duct flows from front to back and finally the gas is discharged into the outside, avoiding direct contact between the user and the odorous substances in the gas, which would cause the user discomfort.

[0063] like Figure 9 and Figure 11 As shown, in this embodiment, the air inlet 42, through hole 31 and air outlet 32 ​​are arranged sequentially from front to back. The axis of the air outlet 32 ​​is set higher than the axis of the air inlet 42, which is conducive to the rapid flow of odor substances with a lower density than air inside the air duct toward the rear air outlet 32.

[0064] like Figures 15 to 17 As shown, in this embodiment, the radial dimension of the receiving cavity 41 formed inside the cover 4 gradually increases from front to back, so as to avoid gas accumulating above the through hole 31 and causing excessive local pressure in the air duct.

[0065] Through the aforementioned additive dispensing device, the interior of the clothing treatment drum is connected to the interior of the water storage box 3 via an air duct, allowing the air inside the clothing treatment drum to flow into the interior of the water storage box 3 via the air duct, and then be discharged to the outside through the air outlet 32 ​​on the side wall of the water storage box 3, thereby allowing the odor substances inside the clothing treatment drum to be quickly discharged.

[0066] Example 2

[0067] like Figure 10 , Figures 12 to 14As shown, this embodiment is a further limitation of the above embodiment one. The interior of the water storage box 3 is provided with an upwardly protruding boss 33. A portion of the top of the boss 33 is recessed downward to form a drainage groove 331. An air outlet 32 ​​is provided on the side wall of the water storage box 3, and a drainage hole 332 communicating with the air outlet 32 ​​is provided on the side wall of the drainage groove 331.

[0068] In this embodiment, the air inside the air duct flows into the water storage box 3 through the through hole 31. The air inside the water storage box 3 further flows toward the drainage hole 332 on the side wall of the drainage groove 331, and finally is discharged into the outside through the air outlet 32, thereby realizing the ventilation of the clothing treatment tube.

[0069] like Figure 10 , Figures 12 to 14 As shown, in this embodiment, the drainage channel 331 is a pressed channel with a notch 333. The air duct is connected to the drainage channel 331 through the notch 333. The notch 333 and the drainage hole 332 are arranged opposite to each other at both ends of the drainage channel 331. The bottom of the drainage channel 331 is an upwardly inclined slope.

[0070] In this embodiment, the air inside the water storage box 3 flows into the drainage groove 331 through the notch 333. The bottom of the drainage groove 331 is an upwardly sloping surface, which is conducive to the upward flow of air along the bottom of the drainage groove 331, and especially conducive to the rapid discharge of odor substances with low density through the drainage hole 332.

[0071] like Figure 10 , Figures 12 to 14 As shown, in this embodiment, a filter 34 is provided inside the drainage channel 331, and the filter 34 is detachably installed on the side wall of the drainage channel 331 via a rotating shaft structure.

[0072] In this embodiment, the filter 34 is installed on the side wall of the diversion groove 331 via a rotating shaft structure, so as to realize the detachable connection between the filter 34 and the side wall of the diversion groove 331, which makes it convenient for users to replace or clean the filter 34 regularly. The filter 34 filters the air flowing into the water storage box 3 through the air duct, preventing dust, lint and other impurities in the air from clogging the diversion hole 332 and causing the air inside the clothes processing drum to be unable to be discharged through the air duct.

[0073] like Figure 10 , Figures 12 to 14 As shown, in this embodiment, the filter 34 includes a filter frame 341 and a filter screen 342 mounted on the filter frame 341. The two ends of the filter frame 341 are respectively attached to the side walls of the flow channel 331 on the opposite side, and the bottom end of the filter frame 341 is attached to the bottom of the flow channel 331. The filter screen 342 filters the air to prevent air from flowing out from both ends of the filter frame 341 and causing the flow holes 332 to become blocked.

[0074] like Figure 10 and Figure 13 As shown, in this embodiment, the filter frame 341 is provided with positioning posts 343 extending toward the side wall of the opposite side drainage groove 331 at both ends. The side wall of the drainage groove 331 is provided with notches 334 for the opposite side positioning posts 343 to be inserted, so that the filter 34 can be detachably installed on the side wall of the drainage groove 331.

[0075] like Figure 12 and Figure 14 As shown, in this embodiment, a limiting block 35 that abuts against the filter 34 is provided in the flow channel 331. The filter 34 and the limiting block 35 are arranged sequentially along the air flow direction so that the filter 34 is firmly installed in the flow channel 331 and the filter 34 is prevented from becoming loose due to the airflow.

[0076] With the above-mentioned additive dispensing device, the filter 34 is detachably installed on the side wall of the diversion channel 331 via a rotating shaft structure, which makes it convenient for users to replace or clean the filter 34. At the same time, the filter 34 filters the air flowing into the water storage box 3 through the air duct, preventing dust, lint and other impurities in the air from clogging the diversion hole 332.

[0077] Example 3

[0078] like Figures 1 to 8 As shown, an additive dispensing device is provided in this embodiment of the invention, including a dispensing box 1. A cover plate 2 is installed on the top of the dispensing box 1. A hollow cavity is formed inside the cover plate 2. An air duct is provided inside the hollow cavity. One end of the air duct is connected to the inside of the dispensing box 1, and the other end is connected to the outside of the dispensing box 1.

[0079] In this embodiment, external air flows into the air duct through the delivery box 1, and then fresh air is introduced into the interior of the clothing processing drum through the air duct. Alternatively, the air inside the clothing processing drum flows into the delivery box 1 through the air duct, and then is discharged to the outside through the delivery box 1. This achieves gas exchange between the interior of the clothing processing drum and the external atmosphere, removes odors from the interior of the clothing processing drum, and improves the user experience.

[0080] like Figure 2 , Figures 3 to 7 As shown, the air duct has an air inlet 23 and an air outlet 24. The air inlet 23 of the air duct is connected to the interior of the dispensing box 1, and the air outlet 24 of the air duct is connected to the exterior of the dispensing box 1.

[0081] In this embodiment, the air inlet 23 of the air duct is connected to the interior of the delivery box 1, so that the air duct is connected to the outside atmosphere. The outside atmosphere flows into the air duct through the air inlet 23, and then fresh air is introduced into the interior of the clothing processing equipment through the air outlet 24 to replace the air inside the clothing processing equipment.

[0082] like Figures 2 to 7As shown, in this embodiment, the cover plate 2 includes an upper cover plate 21 and a lower cover plate 22 that are interlocked with each other. Both the upper cover plate 21 and the lower cover plate 22 are provided with grooves with openings facing each other. The grooves 211 of the upper cover plate 21 and 221 of the lower cover plate 22 cooperate to close the openings and form an air duct. The bottom of the groove 221 of the lower cover plate 22 is provided with an air inlet 23 and an air outlet 24.

[0083] In this embodiment, the upper cover plate 21 and the lower cover plate 22 are interlocked to form a hollow cavity. The interior of the hollow cavity is provided with a water inlet channel for injecting water into the dispensing box 1, while the air duct is closed to prevent gas flowing into the air duct from flowing into the interior of the water inlet channel.

[0084] like Figure 2 , Figure 3 and Figure 7 As shown, in this embodiment, a filter 25 is installed inside the air duct. The filter 25 is inserted into the air duct between the air inlet 23 and the air outlet 24. The filter 25 is detachably installed on the upper cover plate 21 and / or the lower cover plate 22 via a rotating shaft structure.

[0085] In this embodiment, a filter 25 is installed inside the air duct. The filter 25 filters the external air flowing into the air duct to prevent dust, lint and other impurities in the external air from entering the interior of the clothing processing drum through the air outlet 24 of the air duct and causing pollution inside the clothing processing drum.

[0086] like Figure 2 , Figure 3 and Figure 7 As shown, in this embodiment, the groove 221 of the lower cover plate 22 includes a first sidewall and a second sidewall disposed opposite to each other. The filter 25 includes a filter frame 251 and a filter screen 252 installed on the filter frame 251. The two ends of the filter frame 251 are attached to the first sidewall and the second sidewall of the groove 221 of the lower cover plate 22 on the opposite side, and the top of the filter frame 251 is attached to the upper surface of the upper cover plate 21 on the opposite side.

[0087] In this embodiment, the filter frame 251 is attached to the upper cover plate 21 and the lower cover plate 22, so that the gas inside the air duct flows into the clothing processing drum after being filtered by the filter 25, thus preventing dust, lint and other impurities in the external atmosphere from contaminating the clothing processing drum and the clothes inside.

[0088] Preferably, the filter screen 252 is perpendicular to the gas flow direction inside the air duct, which increases the contact area between the filter screen 252 and the gas and enhances the filtration effect.

[0089] like Figures 4 to 6As shown, in this embodiment, the bottom of the groove 221 of the lower cover plate 22 is recessed downward to form an open mounting groove 222 at the upper end. The lower end of the filter frame 251 is provided with a shaft seat 253. The side walls of the shaft seat 253 and the mounting groove 222 are respectively provided with shaft holes for the mounting shaft 26 to pass through, so that the filter 25 is connected to the lower cover plate 22.

[0090] In this embodiment, the filter 25 is mounted on the upper cover plate 21 and / or the lower cover plate 22 via a rotating shaft structure, thereby enabling the filter 25 to be detachably connected to the cover plate 2. This allows the user to disassemble or install the filter 25 themselves, facilitating the user's cleaning or replacement of the filter 25 and further enhancing the user's satisfaction.

[0091] like Figure 2 and Figure 3 As shown, in this embodiment, the bottom end of the bearing seat 253 is embedded in the mounting groove 222 and fits against the bottom of the mounting groove 222 so that the filter 25 can fully filter the gas inside the air duct.

[0092] like Figure 2 and Figure 3 As shown, in this embodiment, the mounting groove 222 has two oppositely arranged side walls, and the two ends of the bearing seat 253 are respectively detachably fixedly connected to the opposite side wall of the mounting groove 222 via a rotating shaft structure.

[0093] In this embodiment, a shaft hole 2221 is provided on the side wall of the mounting groove 222. The shaft hole 2221 includes a first shaft hole and a second shaft hole respectively provided on the two side walls of the mounting groove 222. The two ends of the shaft seat 253 are respectively provided with a first mounting shaft 261 and a second mounting shaft 262 passing through the first shaft hole and the second shaft hole respectively.

[0094] Preferably, the first mounting shaft 261 is integrally connected to the shaft seat 253, and the second mounting shaft 262 is movably connected to the shaft seat 253. The filter 25 is pre-fixed to the lower cover plate 22 through the first mounting shaft 261, and the filter 25 is detachably fixed to the lower cover plate 22 through the second mounting shaft 262.

[0095] like Figure 3 As shown, in this embodiment, the filter 25 also includes a support base 254 extending downward from the bottom end of the filter frame 251. The bottom of the mounting groove 222 is provided with a mounting hole 2222 for the support base 254 to be inserted into. The support base 254 passes through the mounting hole 2222 and is placed between the dispensing box 1 and the lower cover plate 22.

[0096] In this embodiment, by providing a support base 254, it is convenient for users to disassemble or install the filter 25, thereby improving the assembly efficiency of the filter 25 and facilitating the cleaning or replacement of the filter 25 by users.

[0097] like Figures 4 to 6As shown, in this embodiment, a portion of the upper surface of the upper cover plate 21 is recessed upward to form a receiving groove 212 with an open lower end.
