Description

Technical Field

[0001] This invention relates to a clothing treatment device for household appliances, specifically to a clothing treatment device with a non-perforated roller, and particularly to a water inlet and air exchange structure for a non-perforated roller without dehydration holes. Background Technology

[0002] As people's living standards improve, washer-dryer combos and dryers with clothes drying functions are gradually entering people's homes. However, existing washer-dryer combos and dryers generally connect an air duct to the outer drum and install a fan in the air duct to extract the hot and humid air from the outer drum, thereby reducing the humidity inside the drum and drying the clothes.

[0003] Washing machines can be broadly categorized into top-loading, agitator, and front-loading types. Generally, washing machines remove dirt from clothes through the action of water and detergent.

[0004] A drum washing machine typically has a shell, an outer drum for holding washing water installed inside, a drum for holding laundry inside the outer drum, and a motor and shaft for rotating the drum on the back of the outer drum.

[0005] Current drum washing machines generally accumulate a lot of dirt between the inner and outer drums. In order to avoid contaminating the washing water, the applicant previously proposed a holeless drum washing machine that combines the inner and outer drums into one, in order to overcome the problem of dirt accumulation between the inner and outer drums.

[0006] However, existing holeless drum washing machines have the following problems:

[0007] First, because the drum integrates the functions of both a rotating inner drum and a water-holding outer drum, it's impossible to supply water using existing washing machine inlet structures. Second, due to the drum's enclosed design, a ventilation structure is needed to ensure the internal air pressure balances with the external pressure. Therefore, figuring out how to incorporate ventilation and water inlet structures into a holeless drum washing machine, especially how to match the water inlet and ventilation structures to ensure stable water pressure at the inlet, has become a pressing technical challenge.

[0008] In view of this, the present invention is hereby proposed. Summary of the Invention

[0009] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a clothing 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 clothing processing device to achieve the purpose of adjusting the water inlet pressure of the non-porous drum and stabilizing the water inlet flow.

[0010] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0011] A garment processing device includes: a drum, an end cap at the center of the drum bottom, the end cap and the drum bottom together forming a chamber, the chamber being divided into an independent water inlet channel and a ventilation channel, the water inlet channel introducing washing machine water into the drum, and the ventilation channel connecting the inside and outside of the drum.

[0012] 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 cylinder. A sleeve is provided inside the end cap. The two ends of the sleeve are connected to the end cap and the bottom of the drum, respectively. The inside of the sleeve forms a central water inlet channel, and the space between the outside of the sleeve and the inside of the end cap forms an outer circumferential ventilation channel.

[0013] Preferably, the sleeve is integrated with the end cap or the bottom of the sleeve.

[0014] Furthermore, the bottom of the drum is connected to a shaft, the end of which passes through the center of the drum bottom, inserts into the cavity formed by the end cap and the drum bottom. The hollow interior of the shaft forms a flow channel, which connects to the water inlet channel and the washing machine's water inlet pipe.

[0015] Furthermore, a water inlet is provided at the center of the end cap, which connects the inside of the drum with the water inlet channel;

[0016] Preferably, the end cap is hemispherical, with the open side of the hemispherical end cap fastened to the center of the bottom of the drum. The hemispherical end cap is coaxial with the axis of the drum, and the sleeve inside the end cap and the water inlet at the center of the end cap are coaxial with the drum.

[0017] Furthermore, a locking element is threaded onto the outer circumference of the insertion end of the shaft. The locking element is located within the cavity and is fixedly connected to or integrally formed with the end cover.

[0018] Preferably, the locking element is snapped into the end cap, and the snap-in area is provided with at least one sealing ring.

[0019] Furthermore, the end face of the shaft insertion end abuts against the end cover or locking element, and a sealing ring is provided at the abutment.

[0020] Furthermore, at least one through hole is provided on the end cap, and each through hole connects the internal space of the drum to the ventilation channel; at least one exhaust hole is provided on the bottom of the drum, and each exhaust hole connects the ventilation channel to the outside of the drum.

[0021] Preferably, the roller is rotatably mounted on the support, and there is a gap between the support and the bottom of the roller, with the vent hole connecting the gap to the internal space of the roller.

[0022] Furthermore, multiple first through holes are arranged at intervals along the outer periphery of the semi-circular end cap, and the walls of the first through holes are formed by the outer periphery of the end cap and the bottom of the roller.

[0023] And / or, a plurality of second through holes are provided on the wall surface of the semi-circular end cap, each second through hole being located outside the water inlet at the center of the end cap, and the axis of the second through hole being arranged radially along the semi-circular end cap.

[0024] Furthermore, the cross-sectional area of ​​the water outlet is smaller than the cross-sectional area of ​​the water inlet channel;

[0025] Preferably, the water inlet is a tapered hole with a diameter that gradually narrows towards the end connected to the water inlet channel.

[0026] Furthermore, a ring of baffle ribs is provided inside the water inlet. The ring of baffle ribs is coaxially arranged with the water inlet, and the radial length of the outer periphery of the ring of baffle ribs is less than the radial length of the inner wall of the water inlet. The outer periphery of the ring of baffle ribs is connected to the inner wall of the water inlet by at least one connecting rib.

[0027] Preferably, the outer circumference of the circular retaining rib is connected to the inner wall of the water outlet by four connecting ribs arranged at equal intervals and extending radially.

[0028] In a further preferred embodiment, the through hole formed by the circular retaining rib is a tapered hole whose diameter gradually narrows towards the end connected to the water inlet channel.

[0029] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0030] The above configuration integrates the water inlet and air inlet structures of the perforated drum into the end cap at the bottom of the drum, simplifying the equipment and reducing costs. At the same time, by integrating the water inlet channel and the air exchange channel on the same end cap, the air exchange 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 from being too high or too low, which could affect the water flow.

[0031] Meanwhile, the present invention has a simple structure and significant effects, and is intended for widespread use.

[0032] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0039] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0041] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0042] 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.

[0043] like Figures 1 to 4As shown in the embodiment of the present invention, a clothing processing device is introduced, which includes a drum 3. The drum 3 is a barrel-shaped structure without a normally open hole. When the clothing processing device executes the washing program, the drum can independently hold the washing water and can rotate. The rotational force is used to beat the clothes and water to achieve the effect of washing the clothes inside the drum. This avoids the problem that the washing water cross-flows inside and outside the drum 3 during the operation of the clothing processing device, causing the washing water to be contaminated by dirt and bacteria accumulated outside the drum, thus failing to thoroughly clean the clothes.

[0044] At the same time, such as Figures 1 to 4 As shown in the embodiment of the present invention, an end cap 5 is provided at the center of the bottom 1 of the drum 3. The end cap 5 and the bottom of the drum together form a chamber. The chamber is divided into an independent and non-communicating water inlet channel 6 and a ventilation channel 7. The water inlet channel 6 introduces water into the drum 3 to achieve the purpose of water entering the drum 3. At the same time, the ventilation channel 7 connects the inside and outside of the drum 3, so that when the clothes processing equipment is running, the drum 3, which constitutes a sealed container, exchanges gas with the outside through the ventilation channel 7, adjusts the air pressure inside the drum 3, and thus achieves the purpose of normal water inlet and outlet operation of the clothes processing equipment.

[0045] With the above configuration, the end cap 5 at the bottom 1 of the drum 3 integrates both the water inlet and air inlet structures of the non-perforated drum, simplifying the equipment and reducing costs. At the same time, by integrating the water inlet channel 6 and the air exchange channel 7 on the same end cap 5, the air exchange channel 7 is positioned close to the water inlet channel 6, ensuring that the air pressure at the water inlet channel 6 is consistent with the outside of the drum 3, thus preventing the water inlet of the non-perforated drum 3 from being too high or too low and affecting the water flow.

[0046] In this embodiment of the invention, the end cap 5 is disposed inside the drum 3. The end cap 5 is fastened to the side of the bottom of the drum facing inward. After the end cap 5 is fastened, an inward protrusion structure is formed at the center of the bottom 1 of the drum 3. The above-mentioned protrusion structure can be used to lift and agitate the clothes in the drum 3, thereby improving the washing effect.

[0047] In this embodiment of the invention, the end cap 5 has a groove structure with one side open. The grooved end cap 5 is fastened to the center of the bottom of the cylinder 1, so that the end cap 5 and the bottom of the cylinder together form a hollow chamber. A partition is provided in the chamber to divide the chamber into two independent parts, one part being a water inlet channel 6 and the other part being a ventilation channel 7. Preferably, the water inlet channel 6 is located at the center of the chamber and the ventilation channel 7 is located at the outer periphery of the chamber.

[0048] In this embodiment of the invention, a hollow sleeve 8 with open ends is provided in the cavity surrounded by the end cap 5 and the bottom of the cylinder 1. The sleeve 8 extends along the axis of the roller 3, and the two ends of the sleeve 8 abut against the end cap 5 and the bottom of the cylinder 1 of the roller 3, respectively. There is a gap between the outer peripheral wall of the sleeve 8 and the inner wall of the end cap 5, so that the inside of the sleeve 8 forms a water inlet channel 6, and the space between the outer wall of the sleeve 8 and the inner wall of the end cap 5 forms a ventilation channel 7. Preferably, sealing rings are provided at the abutment points of the two ends of the sleeve 8 with the end cap 5 and the bottom of the cylinder 1, so as to ensure the airtight independence between the air inlet channel 6 and the ventilation channel 7, and prevent water from flowing into the ventilation channel 7 and gas from entering the air inlet channel 6.

[0049] In this embodiment of the invention, the sleeve 8 is fixedly installed on the end cap 5 or the bottom of the cylinder 1, or the sleeve 8 is integrally formed with the end cap 5 or the bottom of the cylinder 1; preferably, the sleeve 8 is integrally formed with the end cap 5, one end of the sleeve 8 is fixedly connected to the end cap 5 as a single piece, and the other end is in contact with the bottom of the cylinder 1 of the roller 3. Preferably, at least one sealing ring is provided at the contact point between the sleeve 8 and the bottom of the cylinder 1 of the roller 3 to isolate the inner and outer channels.

[0050] In this embodiment of the invention, a shaft 4 is connected to the bottom 1 of the drum 3. The shaft 4 is coaxially arranged with the drum 3, located on the side of the bottom 1 of the drum 3 and outside the drum 3. The end of the shaft 4 passes through the center of the bottom 1 of the drum 3 and is inserted into the cavity formed by the end cap 5 and the bottom 1. The shaft 4 has a sleeve structure, and its interior has a hollow flow channel 13 extending along the axis and open at both ends. The two ends of the flow channel 13 are respectively connected to the water inlet channel 6 and the washing machine water inlet pipe. In this embodiment of the invention, a water outlet 10 is provided at the center of the end cap 5, and the water outlet 10 is connected to the central water inlet channel 6.

[0051] The above settings enable the water to be introduced into the water inlet channel 6 inside the end cover 5 and flow into the drum 3 through the water outlet 10 opened in the center of the end cover 5, thereby achieving the purpose of water entering the non-perforated drum 3.

[0052] In this embodiment of the invention, the end cap 5 is hemispherical, and the open side of the hemispherical end cap 5 is fastened to the center of the bottom 1 of the drum 3. The hemispherical end cap 5 is coaxially arranged with the axis of the drum 3. The water inlet 10 opened in the center of the end cap 5, the sleeve 8 arranged inside the end cap 5, and the flow channel 13 inside the shaft 4 are all coaxially arranged with the drum 3. The water inlet channel 6 formed by the flow channel 13 and the sleeve 8 are connected in sequence, so that the water supplied by the washing machine water inlet pipe flows through the above structure in sequence before entering the drum.

[0053] To achieve the assembly of shaft 4 and roller 3, the following structure is adopted in this embodiment of the invention:

[0054] like Figures 1 to 4As shown in the embodiment of the present invention, the bottom of the drum 1 is provided with a insertion hole. The insertion end of the shaft 4 is inserted into the inside of the drum 3 through the insertion hole. The outer circumference of the insertion end of the shaft 4 is threaded with a locking member 9. The radial dimension of the locking member 9 is larger than that of the insertion hole, so that the locking member 9 abuts against the side of the bottom of the drum 1 facing the inside of the drum. The part of the shaft 4 outside the drum 3 is a shaft segment with a radial dimension larger than that of the insertion hole. The end face of the shaft segment abuts against the side of the bottom of the drum 1 facing the outside of the drum 3, so that the inserted shaft 4 is locked and clamped to the bottom of the drum 1 by the locking member 9.

[0055] like Figures 1 to 4 As shown, in this embodiment of the invention, the locking member 9 is located in the cavity formed by the end cover 5 and the bottom of the cylinder 1. The locking member 9 is fixedly connected to the end cover 5 or integrally formed with it. Preferably, the locking member 9 is a sleeve-shaped part extending along the axis of the roller 3. The inner peripheral wall of the sleeve-shaped locking member 9 is provided with an internal thread, which engages with the external thread of the locking tongue on the outer peripheral wall of the insertion end of the shaft 4. One end of the locking member 9 is provided with a radially outward protruding annular structure. One side of the annular structure is in contact with the side of the bottom of the cylinder 1 facing the inside of the roller 3. The other end of the locking member 9 is in contact with the end cover 5 and is locked together. A sealing ring 14 is provided at the locking connection to seal the connection between the two parts.

[0056] In this embodiment of the invention, the end face of the insertion end of the shaft 4 abuts against the end cover 5 or the locking member 9, and a sealing ring 14 is provided at the abutment.

[0057] like Figures 1 to 4 As shown, in this embodiment of the invention, the end cap 5 is provided with at least one through hole 11, and each through hole 11 connects the internal space of the roller 3 with the ventilation channel 7; the bottom 1 of the roller 3 is provided with at least one exhaust hole 12, and each exhaust hole 12 connects the ventilation channel 7 with the outside of the roller 3.

[0058] In this embodiment of the invention, the roller 3 is rotatably mounted on a support member, which can be an independent component or other components. Preferably, in this embodiment, the support member is an outer cylinder 2 sleeved outside the roller, and the outer cylinder 2 is telescopically and movablely installed inside the outer shell of the garment processing equipment via a shock-absorbing support member. In this embodiment, there is a gap between the outer cylinder 2 and the bottom 1 of the roller 3, and the vent 12 connects the gap space with the internal space of the roller 3. The gap between the outer cylinder 2 and the roller 3 is also directly connected to the external atmosphere, so that the air pressure inside the roller is consistent with the external atmosphere.

[0059] In this embodiment of the invention, a plurality of first through holes are arranged at intervals along the outer periphery of the semi-circular end cap 5, and the wall of the first through hole is formed by the outer periphery of the end cap 5 and the bottom 1 of the roller 3; and / or, a plurality of second through holes are provided on the wall surface of the semi-circular end cap 5, each second through hole being located outside the water inlet at the center of the end cap 5, and the axis of the second through hole being arranged radially along the semi-circular end cap 5.

[0060] In this embodiment of the invention, the cross-sectional area of ​​the water inlet 10 is smaller than that of the water inlet channel 6; preferably, the water inlet 10 is a tapered hole with a diameter that gradually narrows towards the end connected to the water inlet channel 6.

[0061] In this embodiment of the invention, the water inlet structure for water to enter the roller 3 provided on the end cover 5 is specifically as follows:

[0062] like Figures 1 to 4 As shown, a water inlet 10 is provided through the center of the hemispherical end cap 5. A ring of baffles is provided inside the water inlet 10. The ring of baffles is coaxial with the water inlet 10, and the radial length of the outer periphery of the ring of baffles is less than the radial length of the inner wall of the water inlet 10. The outer periphery of the ring of baffles is connected to the inner wall of the water inlet 10 by at least one connecting rib. Preferably, the outer periphery of the ring of baffles is connected to the inner wall of the water inlet 10 by four connecting ribs that are arranged at equal intervals and extend radially. Thus, the water inlet 10 is divided into a central circular hole water inlet and an outer peripheral annular water inlet by the circular baffle ribs. The outer peripheral annular water inlet is further divided into multiple arc water inlets by the spaced connecting ribs. This causes the water flow from the outer peripheral arc water inlets to spread radially outwards, thereby increasing the spray coverage of the water inlet. At the same time, the water pressure is increased by the centrally narrowed circular hole water inlet, thereby increasing the spray distance of the water flow and achieving the effect of rinsing the drum door.

[0063] In a further preferred embodiment of the invention, the through hole formed by the circular baffle is a tapered hole with a diameter that gradually narrows towards the end connected to the water inlet channel, so as to further increase the spray water pressure and enhance the rinsing effect on the door cover provided on the drum opening side.

[0064] 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. The implementation schemes in the above embodiments can be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
