Description

Technical Field

[0001] The present invention belongs to the technical field of household appliances, and in particular relates to a clothing processing device. Background Art

[0002] In existing drum-type washing machines, the drum generally comprises a housing, within which is mounted an outer drum for holding wash water. Inside the outer drum is a drum for holding laundry. A shaft is located at the bottom of the drum, and a motor is located on the back of the outer drum to rotate the shaft and, in turn, the drum. However, existing drum-type washing machines often retain a significant amount of dirt between the inner and outer drums. To prevent contamination of the wash water, the applicant previously proposed a non-porous drum washing machine that combines the inner and outer drums into one, thus overcoming the problem of dirt remaining between the inner and outer drums.

[0003] In the existing hole-free drum washing machine, an end cover assembly is provided at the center of the drum bottom, and a cavity is formed between the end cover assembly and the drum bottom. A part of the cavity can be used as a water inlet channel. A drum shaft is provided at the drum bottom, and the interior of the drum shaft is hollow to form a flow channel. The drum shaft passes through the drum bottom to connect the flow channel with the water inlet channel. Washing water enters the flow channel from the external water inlet pipe, then enters the water inlet channel through the flow channel, and finally enters the drum from the water inlet channel; the end cover assembly is provided on the drum bottom. When installing the end cover assembly, since there is no structure for positioning the end cover assembly, the end cover assembly is prone to misalignment during installation, and manual labor is required to repeatedly adjust the position of the end cover assembly on the drum bottom to install the end cover assembly. The manual repeated adjustment reduces the assembly effect of the end cover assembly and wastes manpower and time. Summary of the Invention

[0044] Among them, the radial dimension of the positioning portion 811 gradually increases from the positioning portion 811 to the clamping portion 812, and the maximum radial dimension of the positioning portion 811 is the same as the radial dimension of the clamping portion 812. After the positioning portion 811 gradually slides out of the positioning hole 13, as the radial dimension of the positioning portion 811 gradually increases, when the positioning portion 811 slides to the maximum radial dimension, the clamping portion 812 is firmly clamped into the positioning hole 13 through instantaneous force, thereby realizing the positioning of the inner end cover 3.

[0053] In an embodiment of the present invention, the positioning rib 82 is inserted into the positioning groove 124 . Specifically, the rear side of the positioning rib 82 is in contact with the front side of the positioning groove 124 , and the bottom side of the positioning protrusion 81 is in contact with the bottom side of the positioning groove 124 .

[0054] like Figure 4 and Figure 5 As shown, in this embodiment of the present invention, the inner circumferential wall of the inner end cap 3 is provided with a plurality of axially extending connecting ribs 83. The connecting ribs 83 are square in shape, and the front side surfaces of the connecting ribs 83 extend radially to form positioning ribs 82. The positioning ribs 82 are provided on the inner circumferential wall of the inner end cap 3 via the connecting ribs 83. The cylindrical shaft at the rear of the groove is clamped between the inner circumferential walls of the connecting ribs 83. The inner circumferential walls of the connecting ribs 83 are arranged in a close contact with the outer circumferential wall of the cylindrical shaft at the rear of the groove, thereby improving the assembly strength between the positioning ribs 82 and the cylindrical shaft 12.

[0060] like Figure 1-3 As shown, the present invention provides a clothing processing device, including a drum 1, an outer end cover 2 is provided at the center of the drum bottom 11 of the drum 1, and an inner end cover 3 is also provided at the center of the drum bottom 11. The inner peripheral wall of the outer end cover 2, the outer peripheral wall of the inner end cover 3 and the drum bottom 11 together form a chamber 4, and the chamber 4 is divided into a water inlet channel 41 and a ventilation channel 42 which are independent of each other. The water inlet channel 41 introduces external water into the drum 1, and the ventilation channel 42 connects the inside and outside of the drum 1.

[0061] In an embodiment of the present invention, the laundry processing device includes a drum 1. The drum 1 is a barrel-shaped structure without a normally open through hole. When the laundry processing device performs a laundry washing program, the drum 1 can independently hold washing water and rotate. The rotational force is used to beat the clothes and water to achieve the effect of washing the clothes in the drum 1. This avoids the problem of washing water cross-flowing inside and outside the drum 1 during operation of the laundry processing device, causing the washing water to be contaminated by dirt and bacteria accumulated outside the drum and unable to thoroughly wash the clothes. The laundry processing device is a washing machine.

[0062] The water inlet channel 41 introduces the water of the washing machine into the drum 1, thereby achieving the purpose of water filling the drum 1; at the same time, the ventilation channel 42 connects the inside and outside of the drum 1, so that when the clothing processing equipment is running, the drum 1 constituting a sealed container exchanges gas with the outside through the above-mentioned ventilation channel 42, adjusts the air pressure in the drum 1, and thereby achieves the purpose of normal water supply and drainage operation of the clothing processing equipment.

[0063] Through the above-mentioned arrangement, the water inlet and air intake structures of the non-porous drum 1 are integrated between the inner end cover 3 and the outer end cover 2 provided on the bottom 11 of the drum 1, thereby simplifying the equipment and reducing costs; at the same time, by integrating the water inlet channel 41 and the ventilation channel 42 on the above-mentioned two end covers, the ventilation channel 42 is arranged close to the water inlet channel 41, so that the air pressure at the water inlet channel 41 is consistent with that outside the drum 1, thereby avoiding the occurrence of excessive or insufficient pressure at the water inlet of the non-porous drum 1 affecting the water inlet flow.

[0064] The outer end cover 2 is arranged inside the drum 1, and the outer end cover 2 is buckled on the side of the bottom 11 of the drum 1 facing inward. After the end cover is buckled, an inward convex structure is formed at the center of the bottom 11 of the drum 1. The above-mentioned convex structure can be used to lift and stir the clothes in the drum 1, thereby improving the washing effect.

[0066] In an embodiment of the present invention, the outer end cover 2 and the inner end cover 3 are groove-shaped structures with one side open, the inner end cover 3 is buckled on the center of the cylinder bottom 11, the outer end cover 2 is buckled on the outside of the inner end cover 3, and is buckled on the center of the cylinder bottom 11, the outer peripheral wall of the inner end cover 3, the inner peripheral wall of the outer end cover 2 and the cylinder bottom 11 form a chamber 4, and there is no connection between the outer peripheral wall of the inner end cover 3 and the outer peripheral wall of the outer end cover 2. In order to separate the chamber 4 into a front chamber 4 and a rear chamber 4, the front chamber 4 serves as a ventilation channel 42, and the rear chamber 4 serves as a water inlet channel 41. A circle of first bosses 31 is provided on the outer peripheral wall of the inner end cover 3, and the first bosses 31 serve as a partition. The first bosses 31 are sealed and connected to the inner peripheral wall of the outer end cover 2 in a circle, so as to achieve separation of the front chamber 4 and the rear chamber 4;

[0067] like Figure 3 As shown, specifically, the inner circumferential wall of the outer end cover 2 is provided with a circle of second bosses 21, and the rear side of the first boss 31 abuts against the front side of the second boss 21; the first boss 31 and the second boss 21 abut against each other in the front-to-back direction, thereby realizing a sealed connection between the first boss 31 and the inner circumferential wall of the outer end cover 2. In order to realize that the inner end cover 3 is firmly arranged on the bottom 11 of the cylinder, the rear side of the first boss 31 is abutted against the front side of the second boss 21, and the outer end cover 2 plays a role in clamping the inner end cover 3, and can realize surface contact between the first boss 31 and the second boss 21, thereby increasing the sealing between the first boss 31 and the second boss 21; the rear side of the first boss 31 and the front side of the second boss 21 are both horizontal planes extending in the radial direction.

[0068] The front side and the rear side mentioned here are both relative to the front and rear sides of the drum 1, and the front side of the drum 1 is the side where the clothes loading port is provided.

[0069] like Figure 3 As shown, in an embodiment of the present invention, the inner circumferential wall of the inner end cover 3 and the cylinder bottom 11 together form a cavity 5, and a cylinder shaft 12 is connected to the cylinder bottom 11. The end of the cylinder shaft 12 passes through the center of the cylinder bottom 11, is inserted into the cavity 5 and abuts against the inner circumferential wall of the inner end cover 3, and the interior of the cylinder shaft 12 is hollow to form a first flow channel 121, which connects the water inlet channel 41 and the external water inlet pipe.

[0070] In the embodiment of the present invention, the barrel shaft 12 on the barrel bottom 11 extends axially, the inner end cover 3 is a groove-shaped structure with one side open, the inner end cover 3 is snapped onto the barrel bottom 11, and the inner circumferential wall of the inner end cover 3 and the barrel bottom 11 form a cavity 5.

The first flow channel 121 in the barrel shaft 12 extends axially, and the first flow channel 121 has a water inlet and a water outlet. The water inlet of the first flow channel 121 is connected to the external water inlet pipe, which is the water inlet pipe of the washing machine, and the water outlet of the first flow channel 121 is connected to the water inlet channel 41;

[0071] When taking in water, the washing water enters the first flow channel 121 from the water inlet of the first flow channel 121, flows through the first flow channel 121, then enters the water inlet channel through the water outlet of the first flow channel 121, and finally enters the drum 1 through the water outlet of the water inlet channel, thereby realizing water intake of the drum 1.

[0072] like Figure 2 and 3 As shown, in an embodiment of the present invention, a water hole 32 is provided at the center of the inner end cover 3, the first flow channel 121 is connected to the water inlet channel through the water hole 32, and the inner end cover 3 is provided with a first annular sealing ring 6 at the water hole 32, and the end of the cylindrical shaft 12 is against the first annular sealing ring 6.

[0073] In the embodiment of the present invention, a water hole 32 is provided at the center of the inner end cover 3. The inner end cover 3 is a groove-shaped structure. The water hole 32 is provided in the middle of the groove bottom of the inner end cover 3. The cross section of the inner end cover 3 along the axial direction is circular.

The inner diameter of the first annular sealing ring 6 is equal to the inner diameter of the end of the cylinder shaft 12.

[0075] By providing a first annular sealing ring 6 at the junction of the cylindrical shaft 12 and the inner end cover 3, water leakage between the cylindrical shaft 12 and the inner end cover 3 is prevented when water enters the drum 1 through the cylindrical shaft 12, thereby reducing the efficiency of water entering the drum 1. Furthermore, the airtight independence between the air intake passage and the ventilation passage 42 is ensured, preventing water from flowing into the ventilation passage 42 and gas from entering the air intake passage. Specifically, the inner and outer end covers 2, the water passage 32, the flow passage, and the first annular sealing ring 6 are coaxially arranged with the drum 1.

[0077] In the embodiment of the present invention, the first through hole 221 on the outer end cover 2 enables the water inlet channel 41 to communicate with the interior of the drum 1. The wash water entering the water inlet channel 41 enters the drum 1 through the first through hole 221 on the outer end cover 2. The outer end cover 2 has a hemispherical structure. The provision of multiple through holes can increase the efficiency of water inflow into the drum 1.

[0078] Specifically, the outer end cover 2 is provided with a plurality of circles of through-hole units 22, and each circle of through-hole units 22 includes a plurality of first through-holes 221 arranged in a circle along the circumferential direction. The plurality of circles of through-hole units 22 can improve the uniformity of water entering the drum 1, and prevent the washing water from entering the drum 1 through the relatively concentrated first through-holes 221, resulting in poor water inflow; the first through-holes 221 in two adjacent circles of through-hole units 22 are arranged in an staggered manner. If two circles of through-hole units 22 are provided on the outer end cover 2, the first through-holes 221 in one circle of through-hole units 22 are located between two adjacent through-holes in the other circle of through-hole units 22, thereby improving the uniformity of the arrangement of the first through-holes 221 and improving the smoothness of water inflow into the drum 1. When the load in the drum 1 covers part of the first through-holes 221, water can enter the drum 1 from other first through-holes 221.

[0079] When water is entering, if the load covers the first through hole 221, the water flow is blocked and backflow occurs into the water inlet channel. Since the water inlet channel 41 is part of the chamber formed by the inner peripheral wall of the outer end cover 2, the outer peripheral wall of the inner end cover 3 and the bottom 11 of the cylinder, the water inlet channel 41 can be used as a buffer chamber, which is blocked by the sealing gasket to prevent backflow into the ventilation channel 42.

[0080] like Figure 2 As shown, in an embodiment of the present invention, all first through holes 221 in at least one circle of through hole units 22 are connected to a strip-shaped second flow channel 23, which is provided on the outer end cover 2 and extends from the first through holes 221 to the open side of the outer end cover 2.

[0081] In an embodiment of the present invention, the first through hole 221 is connected to the second flow channel 23. When the load covers part of the first through hole 221 of the outer end cover, since the second flow channel 23 is connected to the first through hole 221, the second flow channel 23 can guide the washing water to flow from the second flow channel 221 into the drum 1; specifically, the second flow channel 23 is a groove-shaped structure, and the opening of the groove-shaped second flow channel 23 faces upward.

[0082] like Figure 2 As shown, in an embodiment of the present invention, a plurality of second through holes 24 are further provided on the outer end cover 2, each second through hole 24 connects the internal space of the drum 1 with the ventilation channel 42, and a plurality of exhaust holes 111 are opened on the bottom 11 of the drum, each exhaust hole 111 connects the ventilation channel 42 with the outside of the drum 1.

[0083] In the embodiment of the present invention, a second through hole 24 is further provided on the outer end cover 2. The drum 1 is connected to the ventilation channel 42 through the second through hole 24. The ventilation channel 42 is connected to the outside of the drum 1 through the exhaust hole 111. During ventilation, the gas enters the ventilation channel 42 through the second through hole 24 and then enters the outside of the drum 1 through the exhaust hole 111.

[0084] The plurality of second through holes 24 are close to the open side of the outer end cover 2 , and the plurality of through holes are arranged in a circle along the circumference of the outer end cover 2 , thereby improving the uniformity of the exhaust of the drum 1 .

[0085] like Figure 2 As shown, in the embodiment of the present invention, a third through hole 33 communicating with the ventilation channel 42 is provided on the inner end cover 3 , and an exhaust hole 111 is provided on the bottom 11 of the cavity 5 .

[0086] In the embodiment of the present invention, specifically, the exhaust hole 111 is provided on the drum bottom 11 located in the cavity 5. Therefore, in order to achieve ventilation of the drum 1, a third through hole 33 is provided on the inner end cover 3 to achieve communication between the ventilation channel 42 and the cavity 5, so that gas enters the cavity 5 from the ventilation channel 42 through the third through hole 33 and is then discharged through the exhaust hole 111. The exhaust hole is specifically provided on the drum bottom flange.

[0087] When water overflows from the entire machine, the exhaust hole 111 serves as a drainage hole, and the washing water enters the ventilation channel 42 through the second through hole 24, then enters the cavity 5 through the third through hole 33, and finally enters the drainage pump through the exhaust hole 111 on the bottom flange of the cylinder to drain water and prevent danger. The exhaust hole 111 can be used as the above-mentioned positioning hole 13.

[0088] A plurality of grooves 331 are provided along the circumferential direction on the open side of the inner end cover 3, and each groove 331 and the cylinder bottom 11 together form a third through hole 33; the notches of the grooves 331 provided on the open side of the inner end cover 3 face the cylinder bottom 11, and the grooves 331 have an opening communicating with the ventilation channel 42 and an opening communicating with the cavity 5; the inner circumferential wall of the grooves and the cylinder bottom 11 form the inner circumferential wall of the third through hole 33; the plurality of grooves are arranged in a circle along the circumference of the inner end cover 3.

[0089] like Figure 2 and 3 As shown, in the embodiment of the present invention, a second annular sealing ring 7 is provided on the cylinder bottom 11 , and the open side of the outer end cover 2 abuts against the second annular sealing ring 7 .

[0090] In an embodiment of the present invention, a second annular sealing ring 7 is provided between the bottom 11 of the cylinder and the outer end cover 2 to increase the sealing between the bottom 11 of the cylinder and the outer end cover 2, increase the sealing of the ventilation channel 42, and achieve smooth ventilation of the ventilation channel 42; and since water is brought up by clothes during the washing process, it can prevent the washing water from flowing out along the gap between the bottom 11 of the cylinder and the outer end cover 2, thereby avoiding water leakage.

[0091] Specifically, a circle of recesses 112 with an opening facing the outer end cover 2 is provided on the bottom 11 of the cylinder, and a second annular sealing ring 7 is provided in the recess 112. A circle of recesses 112 is provided on the bottom 11 of the cylinder, and the opening of the recess 112 faces the outer end cover 2. The recess 112 plays a positioning role for the second annular sealing ring 7, thereby reducing the probability of misalignment of the second annular sealing ring 7 and further increasing the sealing between the bottom 11 of the cylinder and the outer end cover 2;

[0092] The second annular sealing ring 7 is provided with a rib on the side facing the outer end cover 2 to increase the sealing contact between the second annular sealing ring 7 and the outer end cover 2; a plurality of ribs are arranged in a circle along the circumference of the second annular sealing ring 7; the second annular sealing ring 7 is coaxially arranged with the drum 1.

[0093] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
