Description

Technical Field

[0001] The invention belongs to the technical field of household appliances, and in particular relates to a pressing cover structure of a washing machine and a washing machine having the pressing cover structure. Background Art

[0002] In an existing type of double-drum washing machine, one drum is a washing drum and the other is a dehydrating drum. The dehydrating drum generates centrifugal force by axial rotation, so that water is thrown out from the holes on the dehydrating drum. During the drying process, the clothes inside the dehydrating drum move up and down, which makes it easy for the clothes to be thrown out of the drum. The existing method is to cover the drum with a rubber cover plate, and the edge of the rubber cover plate is interference fit with the inner surface of the dehydrating drum. However, because the pressure cover of the existing washing machine is generally installed on the lower edge of the balance ring, it is not only difficult to install, but also the washing water consumption is large, and the height cannot be adjusted up and down. When the amount of laundry is small, the pressure cover cannot play the role of pressing the clothes (so that the clothes are soaked in water) and assisting washing (increasing friction). At the same time, because the cover plate is soft and easy to deform, when the rotation and vibration are more intense, it is impossible to stabilize the position only by the friction between the edge of the cover plate and the inner wall of the dehydrating drum, which easily causes the cover plate and the dehydrating drum to rotate relative to each other, and it is easy to cause the cover plate to vibrate up and down, generating noise.

[0003] A Chinese patent application with application number CN201720931511.4 discloses a pulsator washing machine with a press cover. The press cover is assembled in a washing tub through a bracket and can move up and down in the washing tub to press clothes floating on the water surface into the water to achieve a comprehensive washing effect. The bracket is provided with a limiting mechanism that can limit the position of the press cover in the washing tub, so that the fabrics in the water are not easy to float up.

[0004] The Chinese patent application number CN201420813329.5 discloses a washing machine, and more particularly, relates to a washing machine dehydration device. The washing machine dehydration device comprises a dehydration cylinder, wherein a pressure cap is embedded in the dehydration cylinder, and the inner side surface of the dehydration cylinder is provided with a plurality of longitudinally arranged positioning chutes, and the side surface of the pressure cap is provided with a clamping foot that cooperates with the positioning chutes, and the clamping foot is slidably connected with the positioning chutes, and an elastic positioning pin is provided at the clamping foot, and the elastic positioning pin is located in the radial direction of the pressure cap, and the free end of the elastic positioning pin abuts against the bottom of the positioning chutes. A pressure cap is embedded in the dehydration cylinder, and the upper opening of the dehydration cylinder is sealed by the pressure cap to limit the position of the clothes inside the dehydration cylinder, so as to prevent the clothes inside the dehydration cylinder from being thrown out and separated from the dehydration cylinder during the drying process.

[0005] Although the above-mentioned prior art proposes a technical solution for the pressure cover in the washing tub, there are still problems such as complicated installation or adjustment procedures of the pressure cover, cumbersome fixing structure of the pressure cover and the washing tub, poor user experience during operation, and due to mechanical reasons, the fixing structure of the pressure cover has a limited service life, and the existing solution is not easy to replace.

[0006] Therefore, it is necessary to improve the deficiencies and defects of the prior art, and provide a gland structure of a washing machine and a washing machine having the gland structure. By providing a connection assembly on one side of the gland close to the opening direction of the washing tub, and a positioning portion on the inner wall of the washing tub that cooperates with the connection assembly, it is possible to adjust the installation height of the gland arbitrarily according to the amount of laundry, and save washing water consumption; at the same time, users can have a better experience during the process of adjusting or replacing the gland.

[0007] In view of this, the present invention is specifically proposed. Summary of the Invention

[0027] The acting force providing unit is arranged on the connecting arm between the connecting piece and the connection end;

[0028] In one embodiment, when the two connecting arms are in an H-shaped structure, the acting force providing unit is a compression spring structure or a tension spring structure;

[0029] When the two connecting arms are in an X-shaped or V-shaped structure, the acting force providing unit is a compression spring structure.

[0031] A washing machine includes

[0032] The gland structure of a washing machine as described in any one of the above;

[0033] And a washing tub;

[0034] The gland is installed in the washing tub and its height position is adjustable.

[0035] Further, at least one positioning part is provided on the inner wall of the washing tub corresponding to the connection component;

[0036] In the vertical direction, the positioning part is provided with at least two groups of positioning holes corresponding to the connection component at different heights;

[0060] 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 in the embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0061] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0062] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0063] Figure 1 And Figure 2 are the first and second schematic views of the structure of the washing machine with the gland 2 structure according to the present invention. As can be seen from the attached Figure 1 、 2 figures, the gland 2 described in the present invention is arranged inside the washing tub 1. A connection assembly 3 is arranged on the gland 2 facing the opening side of the washing tub 1. A positioning portion 4 is arranged on the inner wall of the washing tub 1, and a positioning groove 5 cooperating with the positioning portion 4 is arranged on the inner wall of the washing tub 1. The user can determine the position height of the gland 2 according to the actual laundry amount. The relative fixation of the gland 2 and the washing tub 1 is achieved through the cooperation of the connection assembly 3 and the positioning portion 4. In one embodiment, the positioning portion 4 can slide in the positioning groove 5 and achieve relative fixation with the positioning groove 5 of the washing tub 1 after determining the appropriate position. This setting makes the adjustment range of the gland 2 larger. At the same time, the setting of the positioning portion 4 avoids the situation of penetrating the side wall of the entire washing tub 1. Ordinary requirements can be achieved by setting several gears only on the positioning portion 4. For special large laundry amounts, further adjustment can be achieved through the adjustment of the positioning portion 4.

[0064] Figure 3 is the schematic view of the assembly structure of the gland 2 and the positioning portion 4 according to the present invention. Through Figure 3 it can be seen that two sets of connection assemblies 3 are symmetrically arranged on the surface of the gland 2 with the center or the center of the circle as the symmetry point. The setting of the connection assembly 3 can be adjusted according to actual needs. If the size of the gland 2 is larger, more sets of connection assemblies 3 are required. At the same time, the connection assembly 3 cooperates with the positioning portion 4 to fix the gland 2.

[0065] Figure 4 is the schematic view of the structure of the connection assembly 3 according to the present invention. Through Figure 4 it can be seen that the connection assembly 3 includes a connecting member 301, a connecting arm 302, and a connecting end 304. Among them, the connecting member 301 is connected to the gland 2. The specific connection method can be an integral fixed connection or a detachable connection. The user applies an external force to the connecting arm 302 to realize the opposite movement of the connecting arm 302, while the connecting end 304 moves in the opposite direction, realizing the disassembly of the connection assembly 3 and the positioning portion 4 arranged on the inner wall of the washing tub 1, and further realizing the height adjustment of the gland 2.

[0066] Figure 5 is a schematic assembly structure diagram of the connection component 3 and the positioning part 4 of the present invention. Through Figure 5 it can be seen the cooperation between the connection component 3 and the positioning part 4. On the side of the positioning part 4, a number of positioning holes 401 are arranged in the vertical direction. The shape of the connection end 304 just fits into the positioning holes 401. The structure is simple and compact, and very beautiful. It is not easy to be found on the top of the washing tub 1, avoiding the overly exposed setting of multiple positioning positions in the prior art.

[0067] Figure 6a , 6b , 6c are three schematic structural diagrams of the connection component of the present invention arranged in an X shape. In the case where the connection component 3 of the present invention is arranged in an X shape, Figure 6a , 6b and 6c and other three situations are listed. The reason for setting these three situations is mainly to consider the usage habits of users in daily life. Mostly, they adopt the posture of holding with one hand and exerting force inward. In order to better conform to the habits of users, Figure 6a , 6b , the three situations shown in 6c are all set based on holding with one hand and exerting force inward. Among them, according to the setting position of the force providing unit 303 and the structural form adopted by the force providing unit 303, different types are distinguished, realizing the requirements of meeting different users, different models and different spaces. For example, Figure 6a , 6b and 6c are all that the connection end 304 of the connection component 3 opens from the inside to the outside, thereby realizing the connection between the connection component 3 and the positioning part 4, and the force providing unit 303 can adopt any one of the compression spring structure and the torsion spring structure according to different settings to realize its function.

[0068] Figure 7a , 7b , 7c are three schematic structural diagrams of the connection component of the present invention arranged in an H shape. In the case where the connection component 3 of the present invention is arranged in an H shape, Figure 7a , 7b and 7c and other three situations are listed. The reason for setting these three situations is mainly to consider the usage habits of users in daily life. Mostly, they adopt the posture of holding with one hand and exerting force inward. In order to better conform to the habits of users, Figure 7a , 7b , the three situations shown in 7c are all set based on holding with one hand and exerting force inward. Among them, according to the setting position of the force providing unit 303 and the structural form adopted by the force providing unit 303, different types are distinguished, realizing the requirements of meeting different users, different models and different spaces. For example, Figure 7a adopts a compression spring structure to realize the cooperation between the connection end 304 of the connection component 3 and the positioning hole 401 of the positioning part 4; Figure 7bThe connection end 304 of the connection component 3 and the positioning hole 401 of the positioning portion 4 are fitted by adopting a tension spring structure; Figure 7c A torsion spring structure is arranged at the connecting piece to realize the fitting of the connecting end 304 of the connecting component 3 and the positioning hole 401 of the positioning portion 4. Among them, the setting position and orientation of the specific torsion spring structure are selected according to the actual situation.

[0069] Figure 8a , 8b FIGS. Figure 8a and Figure 8b are two schematic structural diagrams in which the connection component of the present invention is arranged in a V shape. When the connection component 3 of the present invention is arranged in a V shape, Figure 8a the cooperation between the connection end 304 of the connection component 3 and the positioning hole 401 of the positioning portion 4 is realized by arranging a compression spring structure therein, Figure 8b the cooperation between the connection end 304 of the connection component 3 and the positioning hole 401 of the positioning portion 4 is realized by arranging a torsion spring structure at the connecting piece 301 therein.

[0070] In the present invention, by arranging the connection component 3 on the pressing cover 2 facing the opening side of the washing tub 1 and arranging the positioning portion 4 on the inner wall of the washing tub 1, the height adjustment of the pressing cover 2 in the washing tub 1 according to the amount of laundry is realized; since the connection component 3 is arranged on the pressing cover 2 facing the opening side of the washing tub 1, when the user adjusts the height of the pressing cover 2, directly controlling the connecting arm 302 on the pressing cover 2 can perform the disassembly and assembly operation of the pressing cover 2, avoiding the previous situation of being arranged inside the pressing cover 2 or having a complex fixed structure, etc., and improving the user experience; the structural setting of the connection component 3 can be clamped or disassembled with one hand, greatly improving the operation convenience of the user; further, by arranging the positioning portion 4 capable of height adjustment in the positioning groove on the inner wall of the washing tub 1, the adjustment range of the height of the pressing cover 2 is expanded, so that the pressing cover 2 can be adjusted in a larger range according to the amount of laundry, and the positioning portion 4 itself does not need to penetrate the inner wall of the washing tub 1, only a few gears need to be set. In case of unsuitable height, the relative height of the positioning portion 4 can be adjusted to realize a large-range adjustment of the height of the pressing cover 2.

In the case where the connecting component 3 of the present invention is arranged in an X shape, three cases such as Figure 6a , 6b and 6c are listed. The reason for setting these three cases is mainly to consider the user's usage habits in daily life. Most users adopt a posture of holding with one hand and exerting force inward. In order to better conform to the user's habits, Figure 6a , 6bThe three cases shown in 6c are all set based on the inward force exerted by single - hand clamping. Among them, different types are distinguished according to the setting position of the force - providing unit 303 and the structural form adopted by the force - providing unit 303, meeting the needs of different users, different models, and different spaces.

In order to better conform to the user's habits, Figure 6a 、 6b The three cases shown in Figures 6a, 6b, and 6c are all arranged based on holding with one hand and exerting force inward. Among them, different types are distinguished according to the setting position of the acting force providing unit 303 and the structural form adopted by the acting force providing unit 303, realizing the requirements of meeting different users, different models, and different spaces. For example, Figure 6a 、 6b In Figures 6a, 6b, and 6c, the connection end 304 opens from the inside to the outside, thereby realizing the connection between the connection component 3 and the positioning part 4, and the acting force providing unit 303 can adopt any one of a compression spring structure and a torsion spring structure according to different settings to realize its function.

[0092] Figure 7a 、 7b Figures 7a, 7b, and 7c are three schematic structural diagrams of the connection component of the present invention arranged in an H shape. In the case where the connection component 3 of the present invention is arranged in an H shape, three cases such as Figure 7a 、 7b and 7c are listed. The reason for setting these three cases is mainly to consider the user's usage habits in daily life. Most users adopt a posture of holding with one hand and exerting force inward. In order to better conform to the user's habits, Figure 7a 、 7b, the three cases shown in 7c are all set based on the inward force exerted by single - hand clamping. Among them, different types are distinguished according to the setting position of the force - providing unit 303 and the structural form adopted by the force - providing unit 303, meeting the needs of different users, different models and different spaces. For example Figure 7a A compression spring structure is adopted to realize the cooperation between the connection end 304 of the connection component 3 and the positioning hole 401 of the positioning part 4; Figure 7b A tension spring structure is adopted to realize the cooperation between the connection end 304 of the connection component 3 and the positioning hole 401 of the positioning part 4; Figure 7c A torsion spring structure is set at the connection part to realize the cooperation between the connection end 304 of the connection component 3 and the positioning hole 401 of the positioning part 4. Among them, the setting position and orientation of the specific torsion spring structure are selected according to the actual situation.

[0093] Figure 8a , 8b Figures 6a and 6b are two schematic structural diagrams of the connection component of the present invention being set in a V - shape. In the case where the connection component 3 of the present invention is set in a V - shape, two cases are listed Figure 8a and Figure 8b According to the user's force - exerting habit in daily use, that is, mostly using a single - hand clamping and inward - force - exerting posture, a V - shaped structure that is convenient for operation and occupies less space is adopted. Among them Figure 8a The cooperation between the connection end 304 of the connection component 3 and the positioning hole 401 of the positioning part 4 is realized by setting a compression spring structure in 6a; Figure 8b The cooperation between the connection end 304 of the connection component 3 and the positioning hole 401 of the positioning part 4 is realized by setting a torsion spring structure at the connection part 301 in 6b.

[0094] Embodiment Eight

[0095] This embodiment is a further limitation of any one of the above - mentioned Embodiment One to Embodiment Five. For the gland 2 structure of a washing machine described in this embodiment, the two connecting arms 302 are assembled into any one of an X - shape, an H - shape or a V - shape through the connecting part 301. The two connecting arms 302 rotate relative to the connecting part 301 of the rotating shaft structure, and the force - providing unit 303 is a torsion spring structure and is installed on the connecting part 301.

[0096] Figure 6a , 6b Figures 6a, 6b and 6c are three schematic structural diagrams of the connection component of the present invention being set in an X - shape. In the case where the connection component 3 of the present invention is set in an X - shape, three cases such as 6a, 6b and 6c are listed. The reason for setting these three cases is mainly to consider the user's usage habit in daily life, which is mostly a single - hand clamping and inward - force - exerting posture. In order to be more in line with the user's habit Figure 6a , 6b, the three cases shown in 6c are all set based on the inward force generated by single - hand clamping. Among them, different types are distinguished according to the setting position of the force - providing unit 303 and the structural form adopted by the force - providing unit 303, meeting the needs of different users, different models and different spaces. For example Figure 6a , 6b and 6c both have the connecting end 304 opening from the inside to the outside, thereby realizing the connection between the connecting component 3 and the positioning part 4. The force - providing unit 303 can adopt either a compression spring structure or a torsion spring structure according to different settings to achieve its function.

[0097] Figure 7a , 7b , 7c are three schematic structural diagrams of the connecting component of the present invention arranged in an H - shape. When the connecting component 3 of the present invention is arranged in an H - shape, three cases such as Figure 7a , 7b and 7c are listed. The reason for setting these three cases is mainly to consider the user's usage habits in daily life, which mostly adopt the posture of single - hand clamping and inward force. In order to be more in line with the user's habits, Figure 7a , 7b , the three cases shown in 7c are all set based on the inward force generated by single - hand clamping. Among them, different types are distinguished according to the setting position of the force - providing unit 303 and the structural form adopted by the force - providing unit 303, meeting the needs of different users, different models and different spaces. For example Figure 7a adopts a compression spring structure to realize the cooperation between the connecting end 304 of the connecting component 3 and the positioning hole 401 of the positioning part 4; Figure 7b adopts a tension spring structure to realize the cooperation between the connecting end 304 of the connecting component 3 and the positioning hole 401 of the positioning part 4; Figure 7c adopts a torsion spring structure set at the connecting part to realize the cooperation between the connecting end 304 of the connecting component 3 and the positioning hole 401 of the positioning part 4. Among them, the setting position and orientation of the specific torsion spring structure are selected according to the actual situation.

[0098] Figure 8a , 8b are two schematic structural diagrams of the connecting component of the present invention arranged in a V - shape. When the connecting component 3 of the present invention is arranged in a V - shape, two cases such as Figure 8a and Figure 8b are listed. According to the user's force - exerting habits in daily use, that is, mostly adopting the posture of single - hand clamping and inward force, a V - shaped structure that is easy to operate and occupies less space is adopted. Among them Figure 8a realizes the cooperation between the connecting end 304 of the connecting component 3 and the positioning hole 401 of the positioning part 4 by setting a compression spring structure, Figure 8bThe cooperation between the connecting end 304 of the connecting component 3 and the positioning hole 401 of the positioning portion 4 is achieved by providing a torsion spring structure at the connecting member 301.

[0099] Embodiment Nine

[0100] As Figures 1 to 5 shown, this embodiment is a further limitation of any one of the above-mentioned Embodiments One to Eight. The washing machine described in this embodiment includes the gland 2 structure of any one of the above-mentioned washing machines; and a washing tub 1.

[0101] The gland 2 is installed inside the washing tub 1 and its height position is adjustable.

[0102] Embodiment Ten

[0103] As Figures 1 to 5 shown, this embodiment is a further limitation of the above-mentioned Embodiment Nine. The washing machine described in this embodiment has the washing tub 1 including at least two positioning portions 4, which are evenly arranged along the circumference on the inner wall of the washing tub 1; in the vertical direction, the positioning portion 4 is provided with at least two groups of positioning holes 401 corresponding to the connecting component 3; the connecting component 3 cooperates with the positioning holes 401 of the positioning portion 4 to realize the adjustment of the gland 2 at different heights inside the washing tub 1; further, the connecting component 3 is arranged on the surface of the gland 2 facing the opening of the washing tub 1.

[0104] Figure 1 and Figure 2 are the first and second schematic structural diagrams of the washing machine with the gland 2 structure of the present invention. As can be seen from the attached Figure 1 、 2 figures, the gland 2 of the present invention is arranged inside the washing tub 1. A connecting component 3 is arranged on the side of the gland 2 facing the opening of the washing tub 1. A positioning portion 4 is arranged on the inner wall of the washing tub 1, and a positioning groove 5 cooperating with the positioning portion 4 is arranged on the inner wall of the washing tub 1. The user can determine the position height of the gland 2 according to the actual laundry volume. The relative fixation of the gland 2 and the washing tub 1 is achieved through the cooperation between the connecting component 3 and the positioning portion 4. In one embodiment, the positioning portion 4 can slide in the positioning groove 5 and achieve relative fixation with the positioning groove 5 of the washing tub 1 after determining the appropriate position. This setting makes the adjustment range of the gland 2 larger. At the same time, the setting of the positioning portion 4 avoids the situation of penetrating the side wall of the entire washing tub 1. Ordinary requirements can be achieved by setting only a few positions on the positioning portion 4. For special large laundry volumes, further adjustment can be achieved through the adjustment of the positioning portion 4.

[0105] Embodiment Eleven

[0106] As Figures 1 to 5As shown, this embodiment is a further limitation of the above-mentioned Embodiment Nine or Embodiment Ten. At least two oppositely arranged positioning grooves 5 are provided on the inner wall of the washing tub 1 described in this embodiment; the positioning portion 4 is arranged in the positioning groove 5; the positioning portion 4 can adjust the relative height position along the area formed by the positioning groove 5 in the vertical direction. Figure 5 Figure Figure 5 is a schematic assembly structure diagram of the connection component 3 and the positioning portion 4 of the present invention. Through the figure, the cooperation between the connection component 3 and the positioning portion 4 can be seen. On the side portion of the positioning portion 4, a number of positioning holes 401 are provided in the vertical direction. The shape of the connection end 304 just fits into the positioning holes 401. The structure is simple and compact, and very beautiful. It is not easy to be found on the top of the washing tub 1, avoiding the overly exposed arrangement of multiple positioning positions in the prior art. Further, by providing the positioning portion 4 capable of height adjustment in the positioning groove on the inner wall of the washing tub 1, the adjustment range of the height of the gland 2 is expanded, enabling the gland 2 to be adjusted within a larger range according to the amount of laundry. And the positioning portion 4 itself does not need to penetrate the inner wall of the washing tub 1, only a few gear settings are required. In case of unsuitable height, the large-range adjustment of the height of the gland 2 can be achieved by adjusting the relative height of the positioning portion 4. The position adjustment between the positioning portion 4 and the positioning groove 5 can be realized by providing a slideway and a positioning clamping structure. In addition, it can also be connected by threads and other means. Similar slideway settings in this field are relatively common, and will not be elaborated here too much.

[0107] Embodiment Twelve

[0108] One set of connection components 3 can be provided for the gland 2 described in the present invention. A positioning portion 4 is provided on the inner wall of the washing tub 1 corresponding to the connection component 3. At a position centrosymmetric with the center of the positioning portion 4 on the inner wall of the washing tub 1, a clamping portion (not shown in the figure) for restricting the movement of the gland 2 in the height direction is provided. The number of height adjustment gears of the clamping portion corresponds to that of the positioning portion 4. During installation, first install the gland 2 on the clamping portion, and then install the connection component 3 on the positioning portion 4. Conversely, during disassembly, first remove the connection component 3 and the positioning portion 4, and then take out the gland 2 from the clamping portion.
