Abstract
Description
Technical Field
[0001] This invention belongs to the field of household appliance technology, and more specifically, relates to a clothing processing device. Background Technology
[0002] In existing drum washing machines, the drum typically has a shell, with an outer drum inside to hold the washing water. Inside the outer drum is a inner drum to hold the laundry. A shaft is located at the bottom of the drum, and a motor is located on the back of the outer drum to drive the shaft and thus rotate the drum. However, current drum washing machines generally accumulate a large amount of dirt between the inner and outer drums. To avoid contaminating the washing water, the applicant previously proposed a perforated drum washing machine that combines the inner and outer drums into one, thus overcoming the problem of dirt accumulation between them.
[0003] Existing non-perforated drum washing machines have the following problems: because the drum integrates the functions of a rotating inner drum and a water-holding outer drum, it is impossible to supply water to it using the existing washing machine water inlet structure; at the same time, because the drum is enclosed, a ventilation structure needs to be added to the drum to ensure that the air pressure inside the drum is balanced with the outside air pressure. Therefore, how to set up a ventilation structure and a water inlet structure in a non-perforated drum washing machine, especially how to match the water inlet structure with the ventilation structure to ensure stable water pressure at the water inlet, has become an urgent technical problem to be solved.
[0004] In view of this, the present invention is hereby proposed. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a clothes processing device to achieve the purpose of integrating ventilation and water inlet structures on a non-porous drum washing machine; at the same time, another objective of the present invention is to provide a clothes processing device to achieve the purpose of adjusting the water inlet pressure of the non-porous drum and stabilizing the water inlet flow.
[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:
[0007] The present invention provides a garment processing device, including a roller, an end cap at the center of the bottom of the roller, the end cap and the bottom of the roller together forming a chamber, a pipe is provided in the chamber, the inside of the pipe forms a ventilation channel connecting the inside and outside of the roller, and the space between the outside of the pipe and the inside of the chamber forms a water inlet channel for introducing external water into the roller.
[0008] Furthermore, the end cap has a groove structure with one side open. The grooved end cap is fastened to the center of the bottom of the drum. One end of the pipe is connected to the inner wall of the end cap. The end cap has a vent hole, which connects the space inside the drum with the ventilation channel.
[0009] Furthermore, an exhaust hole is provided on the bottom of the drum, and the other end of the pipe is inserted into the exhaust hole at the bottom of the drum, connecting the ventilation channel to the outside of the drum.
[0010] Furthermore, the drum is rotatably mounted on the support, and there is a gap between the support and the bottom of the drum. The exhaust hole connects the gap space with the ventilation channel.
[0011] Preferably, the end cap is coaxially arranged with the bottom of the drum, and the pipe gradually slopes towards the axis of the bottom of the drum along the direction from the bottom of the drum to the end cap.
[0012] Furthermore, the outer periphery of the vent hole is provided with a guide section to direct water flow on the outer wall of the end cap or the bottom of the drum to other places.
[0013] Furthermore, the flow guide is arc-shaped and protrudes from the vent on the end cap. The flow guide is located between the outer periphery of the vent and the outer periphery of the end cap. The two ends of the flow guide in the extension direction are respectively connected to the opposite sides of the vent. The outer peripheral surface of the flow guide is the flow guide surface.
[0014] Preferably, the dimensions of the flow guide gradually decrease from the center to both sides in the circumferential direction of the end cap.
[0015] Furthermore, an inlet pipe is installed inside the inlet channel. The two ends of the inlet pipe are connected to the end cover and the bottom of the drum, respectively. The inside of the inlet pipe forms the main inlet channel, and the space between the outside of the inlet pipe and the inside of the inlet channel forms the auxiliary inlet channel. The main inlet channel and the auxiliary inlet channel are connected.
[0016] Furthermore, a cylindrical shaft is connected to the bottom of the drum, and the hollow interior of the cylindrical shaft forms a flow channel. The main water inlet channel extends out of the bottom of the drum and communicates with the flow channel inside the cylindrical shaft.
[0017] Furthermore, a main water inlet is provided at the center of the end cap, which connects the inside of the drum with the main water inlet channel;
[0018] Preferably, the end cap is hemispherical, and the open side of the end cap is fastened to the center of the bottom of the cylinder. The main water inlet channel and the main water inlet hole are coaxially arranged with the drum.
[0019] More preferably, the end cap is also provided with an auxiliary water inlet hole, which connects the inside of the drum with the auxiliary water inlet channel.
[0020] Furthermore, the inner wall of the end cap is provided with several protrusions, which are located on the outer periphery of the main water inlet and arranged circumferentially along the main water inlet. One end of the water inlet pipe is connected to each protrusion, and an anti-blocking opening is formed between the end of the water inlet pipe, the inner wall of the end cap, and the protrusions. The main water inlet channel is connected to the auxiliary water inlet channel through the anti-blocking opening.
[0021] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.
[0022] By installing pipes inside the chamber, the chamber is divided into a water inlet channel and a ventilation channel. The ventilation channel is positioned close to the water inlet channel, ensuring that the air pressure at the water inlet channel is consistent with that outside the drum. This prevents the water inlet of the non-perforated drum from being too high or too low, which could affect the water flow.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0034] like Figure 1-4 As shown, the present invention provides a garment processing device, including a roller, an end cap 1 at the center of the bottom 6 of the roller, the end cap 1 and the bottom 6 of the roller together form a chamber, a pipe 2 is provided in the chamber, the inside of the pipe 2 forms a ventilation channel 3 connecting the inside and outside of the roller, and the space between the outside of the pipe 2 and the inside of the chamber forms a water inlet channel 4 for introducing external water into the roller.
[0035] In an embodiment of the present invention, a pipe 2 is provided in the chamber, which divides the chamber into a water inlet channel 4 and a ventilation channel 3. The ventilation channel 3 is positioned close to the water inlet channel 4, so that the air pressure at the water inlet channel is consistent with that at the outside of the drum. This avoids the phenomenon that the pressure at the water inlet of the non-perforated drum is too high or too low, which would affect the water flow.
[0036] This garment processing device includes a drum, which is a barrel-shaped structure without a normally open hole. During the washing cycle, the drum can independently hold washing water and rotate, using the rotational force to tumble the clothes and water, thus achieving the washing effect. This avoids the problem of washing water flowing between the inside and outside of the drum during operation, which can cause the washing water to be contaminated by dirt and bacteria accumulated on the outside of the drum, preventing thorough cleaning of the clothes. This garment processing device is a washing machine; the drum and drum shaft are... Figure 1 Not shown in the image.
[0037] The water inlet channel 4 introduces water into the drum of the washing machine, achieving the purpose of water entering the drum; at the same time, the ventilation channel 3 connects the inside and outside of the drum, so that when the clothes processing equipment is running, the drum, which forms a sealed container, exchanges gas with the outside through the ventilation channel 3, adjusts the air pressure inside the drum, and thus achieves the purpose of normal water intake and drainage operation of the clothes processing equipment.
[0038] With the above configuration, the end cap 1 at the bottom 6 of the drum integrates the water inlet and air inlet structure of the non-perforated drum, simplifying the equipment and reducing costs. At the same time, by integrating the water inlet channel 4 and the air exchange channel 3 on the end cap 1, the air exchange channel 3 is positioned close to the water inlet channel 4, so that the air pressure at the water inlet channel 4 is consistent with that at the outside of the drum, thus avoiding the phenomenon that the pressure at the water inlet of the non-perforated drum is too high or too low, which would affect the water flow.
[0039] End cap 1 is located inside the drum. End cap 1 is fastened to the side of the drum bottom facing inward. After the end cap 1 is fastened, an inward protrusion structure is formed at the center of the drum bottom 6. The above-mentioned protrusion structure can be used to lift and agitate the clothes in the drum, thereby improving the washing effect.
[0040] like Figure 1 , Figure 2 and Figure 4 As shown, in an embodiment of the present invention, the end cap 1 has a groove structure with one side open. The grooved end cap 1 is fastened to the center of the bottom 6 of the drum. One end of the pipe 2 is connected to the inner wall of the end cap 1. The end cap 1 is provided with a vent hole 11, which connects the space inside the drum with the ventilation channel 3.
[0041] In an embodiment of the present invention, the end cap 1 is a groove structure with one side open, so that the end cap 1 has an inner wall and an outer wall of the groove. When fastened, one side of the end cap 1 faces the bottom 6 of the drum, and the open side of the end cap 1 is sealed to the bottom of the drum, so that a cavity is formed between the inner wall of the end cap 1 and the bottom of the drum. The pipe 2 is disposed in the cavity, and one end of the pipe 2 is connected to the inner wall of the end cap 1. The end cap 1 is provided with a vent hole 11. The inside of the drum is connected to the ventilation channel 3 through the vent hole 11. For example, the gas inside the drum can enter the ventilation channel 3 through the vent hole 11, and the gas is then discharged to the outside through the ventilation channel 3.
[0042] The chamber is provided with several pipes 2, that is, several ventilation channels 3. The end cover 1 is provided with several vent holes 11 corresponding to each ventilation channel 3. Each vent hole 11 is connected to a ventilation channel 3. The end cover 1 is hemispherical. Several vent holes 11 are evenly distributed in a circle along the circumference of the end cover 1 to improve the uniformity of ventilation inside the drum.
[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the embodiment of the present invention, an exhaust hole 61 is provided on the bottom 6 of the drum, and the other end of the pipe 2 is inserted into the exhaust hole 61 at the bottom of the drum. The exhaust hole 61 connects the ventilation channel 3 to the outside of the drum.
[0044] In an embodiment of the present invention, the other end of the pipe 2 is inserted into the vent hole 61 at the bottom of the cylinder. It can be inserted into the vent hole 61 or pass through the vent hole 61. The vent hole 61 is provided so that the ventilation channel 3 is connected to the outside of the drum. For example, the gas inside the drum enters into the ventilation channel 3 through the vent hole 11, and the gas in the ventilation channel 3 is discharged to the outside of the drum through the vent hole 61.
[0045] Specifically, the roller is rotatably mounted on the support 7, and there is a gap between the support 7 and the bottom 6 of the roller. The exhaust hole 61 connects the gap space with the ventilation channel 3. The support 7 is a tripod 71, and the roller shaft is rotatably mounted on the tripod.
[0046] More preferably, the end cap 1 is coaxially arranged with the bottom 6 of the drum, and the pipe 2 gradually slopes towards the axis of the bottom 6 of the drum along the direction from the bottom 6 of the drum to the end cap 1. Since washing water may remain on the end cap 1 or the bottom 6 of the drum, in order to avoid the washing water remaining in the vent hole 11, the pipe 2 is inclined. The pipe 2 slopes towards the axis of the end cap 1 or the axis of the bottom 6 of the drum from the bottom 6 of the drum to the end cap 1, so that the washing water entering the vent hole 11 can flow out at an angle. This can be understood as the washing water being able to flow out from top to bottom into the interior of the drum.
[0047] like Figure 2 and Figure 4 As shown, in an embodiment of the present invention, the outer periphery of the vent hole 11 is provided with a guide portion 5 to guide the water flow on the outer wall of the end cap 1 or the bottom 6 of the drum to other places.
[0048] In an embodiment of the present invention, since washing water may remain on the end cap 1 or the bottom 6 of the drum, the washing water will enter the vent hole 11 along the outer wall of the end cap 1. In order to prevent the washing water from entering the vent hole 11, a guide portion 5 is provided on the outer periphery of the vent hole 11. The guide portion 5 is used to guide the water flow away from the vent hole 11.
[0049] Furthermore, the flow guide 5 is arc-shaped and protrudes from the vent hole 11 on the end cap 1. The flow guide 5 is located between the outer periphery of the vent hole 11 and the outer periphery of the end cap 1. The two ends of the flow guide 5 in the extension direction are respectively connected to the opposite sides of the vent hole 11. The outer peripheral surface of the flow guide 5 is the flow guide surface 51.
[0050] The guide section 5 protrudes outward from the vent hole 11 on the end cap, which acts as a shield to prevent the washing water on the outer wall of the end cap 1 from entering the vent hole 11. Since the washing water remaining at the bottom of the drum flows from the outer periphery of the end cap to the outer wall of the end cap, the guide section 5 is located between the outer periphery of the vent hole 11 and the outer periphery of the end cap 1. The guide section 5 extends along the outer periphery of the vent hole 11, and the two ends of the extension direction of the guide section 5 are connected to the opposite sides of the vent hole 11, thereby further preventing the washing water from entering the vent hole 11. The guide section 5 is arc-shaped, so that the outer peripheral surface of the guide section 5 is a smooth curved surface, which can accelerate the flow of washing water.
[0051] More specifically, the dimensions of the guide section 5 gradually decrease from the center to both sides in the circumferential direction of the end cover 1, further accelerating the flow of washing water through the guide section 5.
[0052] like Figure 1 , Figure 2 and Figure 3 As shown, in an embodiment of the present invention, a water inlet pipe 41 is provided inside the water inlet channel 4. The two ends of the water inlet pipe 41 are respectively connected to the end cover 1 and the bottom 6 of the drum. The inside of the water inlet pipe 41 forms a main water inlet channel 411. The space between the outside of the water inlet pipe 41 and the inside of the water inlet channel 4 forms an auxiliary water inlet channel 42. The main water inlet channel 411 and the auxiliary water inlet channel 42 are connected.
[0053] In an embodiment of the present invention, the water inlet pipe 41 divides the water inlet channel 4 into a main water inlet channel 411 and an auxiliary water inlet channel 42. When water is introduced, most of the washing water flows out from the main water inlet channel 411 into the inside of the drum, and a small portion of the washing water flows out from the auxiliary water inlet channel 42 into the inside of the drum.
[0054] In particular, when the main water inlet channel 411 is blocked by clothes, since the main water inlet channel 411 is connected to the auxiliary water inlet channel 42, the washing water can enter the auxiliary water inlet channel 42 through the main water inlet channel 411, and then enter the inside of the drum through the auxiliary water inlet channel 42, so that the washing water can enter the inside of the drum normally without being affected by the clothes inside the drum.
[0055] An annular sealing ring is provided on the bottom 6 of the drum, and the open side of the end cover 1 abuts against the annular sealing ring. An annular sealing ring is provided between the bottom 6 of the drum and the end cover 1 to increase the sealing between the bottom 6 of the drum and the end cover 1, and to increase the sealing of the water inlet channel 4, especially the auxiliary water inlet channel 42, so as to prevent washing water from leaking from inside and outside the water inlet channel 4.
[0056] Specifically, the bottom 6 of the drum is provided with a recess with an opening facing the end cover 1. An annular sealing ring is provided in the recess. The bottom 6 of the drum is provided with a recess with an opening facing the end cover 1. The recess plays a positioning role for the annular sealing ring, reducing the probability of misalignment of the annular sealing ring and further increasing the sealing between the bottom 6 of the drum and the end cover 1.
[0057] The annular sealing ring has raised ribs on the side facing the end cover to increase the sealing contact between the annular sealing ring and the end cover; several raised ribs are arranged in a circle around the circumference of the annular sealing ring; the annular sealing ring is coaxial with the roller.
[0058] like Figures 1-4 As shown, in an embodiment of the present invention, a cylindrical shaft is connected to the bottom 6 of the drum, and the inside of the cylindrical shaft is hollow to form a flow channel. The main water inlet channel 411 extends out of the bottom 6 of the drum and communicates with the flow channel inside the cylindrical shaft.
[0059] In an embodiment of the present invention, during water intake, the washing water enters the main water intake channel 411 from the flow channel inside the drum shaft. Most of the washing water in the main water intake channel 411 directly enters the interior of the drum, while a small portion of the washing water enters the auxiliary water intake channel 42 and enters the interior of the drum through the auxiliary water intake channel 42.
[0060] A first through hole 62 is provided on the bottom 6 of the drum. The water inlet pipe 41 passes through the first through hole 62 and exits the bottom of the drum. That is, the main water inlet channel 411 passes through the first through hole 62 and exits the bottom of the drum. A second through hole 72 is provided on the tripod 71. The drum shaft is rotatably connected to the tripod 71 through the second through hole 72. The water inlet pipe 41 is located on the tripod 71 and communicates with the flow channel inside the drum shaft. The first through hole 62, the second through hole 72, the drum, and the water inlet pipe 41 are coaxially arranged.
[0061] Specifically, a main water inlet hole 12 is provided at the center of the end cover 1, which connects the inside of the drum with the main water inlet channel 411. When water is introduced, the washing water in the main water inlet channel 411 enters the inside of the drum through the main water inlet hole 12 on the end cover 1. The end cover 1 is hemispherical, and the open side of the end cover 1 is fastened to the center of the bottom of the drum. The main water inlet channel 411 and the main water inlet hole 12 are both coaxially arranged with the drum. Several vent holes 11 are provided on the end cover 1. The vent holes 1 are located on the outer periphery of the main water inlet hole 12 and are distributed in a ring at intervals along the circumference of the main water inlet hole 12. Since the end cover 1 is hemispherical and the main water inlet hole 12 is at the center of the end cover 1, the center position of the end cover 1 is high, which can effectively prevent washing water from entering the vent holes 11.
[0062] Specifically, the end cap 1 is also provided with an auxiliary water inlet hole 13, which connects the inside of the drum with the auxiliary water inlet channel 42. During water intake, the washing water entering the auxiliary water inlet channel 42 from the main water inlet channel 411 enters the inside of the drum through the auxiliary water inlet hole 13;
[0063] The auxiliary water inlet 13 includes several auxiliary water inlet holes 131 and several auxiliary water inlet holes 132. The auxiliary water inlet holes 131 are located on the outer periphery of the main water inlet 12 and are distributed in a circle along the circumference of the main water inlet 12. The vent holes 11 and the auxiliary water inlet holes 131 are distributed in a circle along the circumference of the main water inlet 12, and the vent holes 11 and the auxiliary water inlet holes 131 are distributed alternately. The auxiliary water inlet holes 132 are located on the outer periphery of the main water inlet 12 and are distributed in a circle along the circumference of the main water inlet 12. The auxiliary water inlet holes 132 are located on the outer periphery of the auxiliary water inlet holes 131 and the vent holes 11, and are located on the outer periphery edge of the end cap 1. The main water inlet 12 and the auxiliary water inlet holes 131 are both circular holes, and the size of the main water inlet 12 is larger than the size of the auxiliary water inlet holes 131. The auxiliary water inlet holes 132 are elongated holes that extend along the circumference of the end cap 1.
[0064] When the drum is full of clothes and blocks the main water inlet 12, the washing water entering from the main water inlet channel 411 enters the auxiliary water inlet channel 42. The washing water in the auxiliary water inlet channel 42 enters the interior of the drum through the auxiliary water inlet hole 131 and the auxiliary water inlet hole 2132. Since the auxiliary water inlet hole 2132 is located on the outer periphery of the end cover 1 and the end cover 1 is hemispherical, the auxiliary water inlet hole 2132 is basically unaffected by the situation of the drum being full of clothes.
[0065] like Figure 3 As shown, in an embodiment of the present invention, the inner wall of the end cap 1 is provided with a plurality of protrusions 14. The plurality of protrusions 14 are provided on the outer periphery of the main water inlet hole 12 and are arranged along the circumference of the main water inlet hole 12. One end of the water inlet pipe 41 is connected to each protrusion 14. An anti-blocking port 43 is formed between the end of the water inlet pipe 41, the inner wall of the end cap 1, and the protrusions 14. The main water inlet channel 411 is connected to the auxiliary water inlet channel 42 through the anti-blocking port 43.
[0066] In an embodiment of the present invention, the main water inlet channel 411 and the auxiliary water inlet channel 42 are connected as follows: the inner wall of the end cap 1 is provided with a plurality of protrusions 14, which are located on the outer periphery of the main water inlet hole 12 and are distributed in a ring at intervals along the circumference of the main water inlet hole 12. There is a gap between two adjacent protrusions 14. The end of the water inlet pipe 41 is connected to each protrusion 14, so that the inner wall of the end cap 1, two adjacent protrusions 13 and the end of the water inlet pipe 41 form an anti-blocking opening 43, so that the main water inlet channel 411 is connected to the auxiliary water inlet channel 42 through the anti-blocking opening 43, so that the washing water in the main water inlet channel 411 enters the auxiliary water inlet channel 42 through the anti-blocking opening 43.
[0067] In addition, a through hole can be provided on the outer peripheral wall of the water inlet pipe 41 to prevent blockage, thereby connecting the main water inlet channel 411 with the auxiliary water inlet channel 42.
[0068] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention.
