Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, in particular to an inner tank component for a washing machine and a washing machine. Background Art

[0002] The inner tank of a dishwasher can be made of metal or plastic.

[0003] For example, the Chinese patent application number CN202022663911.6, "An independent and embedded compatible dishwasher frame and a dishwasher installed therewith", uses a plastic base to form the bottom of the inner tank. Since the bottom of the inner tank constituting the bottom wall of the washing chamber needs to be formed into a diversion structure or other functional shapes, it is more convenient to use plastic parts for production. However, due to the influence of the plastic parts themselves on the water flow tension, the diversion effect and drying effect of the bottom wall of the washing chamber formed by the plastic parts are poor. The Chinese patent application number CN202220394110.0, "A dishwasher inner tank assembly", uses metal materials to make the inner tank. In order to facilitate production and assembly, the upper and bottom parts of the inner tank are fixed and sealed in the form of biting edges. This is also a common production method for this type of metal inner tank. Although it improves the diversion effect and drying effect of the bottom of the washing chamber, the strength of the all-metal inner tank structure is poor, and the equipment required for the biting edge process is complex, the production investment is large, and the cost is high.

[0004] Therefore, further improvements are needed to be made to the inner tank assembly structure currently used in cleaning machines. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide an inner tank assembly for a cleaning machine which is easy to produce and manufacture and has good diversion and drying effects in view of the current status of the prior art.

[0006] The second technical problem to be solved by the utility model is to provide a cleaning machine using the above-mentioned inner tank assembly in view of the current status of the prior art.

[0007] The technical solution adopted by the utility model to solve at least one of the above technical problems is:

[0008] An inner tank assembly for a cleaning machine, comprising:

[0009] The liner body includes a metal top plate and side plates, wherein the top plate and the side plates together enclose a cavity with an open lower end;

[0010] A base assembly, connected to the bottom of the inner tank body, used to cover the opening to form a complete washing chamber;

[0011] The base assembly comprises:

[0012] A base, made of plastic material, supported under the inner tank body;

[0013] The inner tank bottom plate is made of metal material, the edge of the inner tank bottom plate is mounted on the top of the base, and the inner tank bottom plate covers the lower end opening of the inner tank body to enclose a complete washing chamber with the inner tank body;

[0014] The assembly ring is made of plastic material and is clamped between the bottom of the inner tank body and the top of the base, forming a first sealing structure sealed to the bottom plate of the inner tank and a second sealing structure sealed to the bottom edge of the inner tank body.

[0015] Preferably, the edge of the bottom plate of the inner container extends upward to form a side connecting plate, the top edge of the side connecting plate extends outward to form an overlapped edge, the top of the base forms a supporting surface for the overlapped edge to be mounted thereon, the bottom of the assembly ring forms a holding surface against the upper surface of the overlapped edge, and the holding surface and the supporting surface clamp the overlapped edge therebetween. In this way, the upper and lower metal parts are connected together by using a plastic assembly ring, which facilitates the production and assembly of various components.

[0016] Preferably, the supporting surface is provided with a convex card extending upward, and correspondingly, the overlapping edge is provided with a bayonet opening which passes through the upper and lower parts and allows the convex card to pass through, and the pressing surface is provided with a slot for the convex card to be buckled therein. When assembling the base, the liner bottom plate, and the assembly ring, the matching structure of the convex card, the bayonet opening, and the slot can realize the pre-positioning of each component to facilitate the subsequent locking and fixing.

[0017] Preferably, the cross section of the bottom of the assembly ring is formed into an inverted L-shaped structure, which covers the junction of the side connecting plate and the overlapping edge, the horizontal part of the L-shaped structure is pressed on the overlapping edge, and the vertical part of the L-shaped structure is arranged close to the inner wall of the side connecting plate. This structure is conducive to improving the compactness and sealing of the assembly between the components.

[0018] Preferably, the overlapped edge is partially arched downward near the corner of the L-shaped structure to form a sealing rib, which is a closed-loop structure arranged circumferentially around the corner of the L-shaped structure. This structure can further improve the sealing between the assembly ring and the bottom plate of the inner tank to prevent hot water or high-temperature steam from overflowing.

[0019] Further preferably, the cross section of the sealing rib is a trapezoidal structure or a V-shaped structure or a bowl-shaped structure with a large upper part and a small lower part, and the bottom of the sealing rib is tightly sealed with the supporting surface. When the holding surface presses the sealing rib against the supporting surface, the metal lap edge located at the periphery of the sealing rib maintains a tendency to press upward against the holding surface. Since the bottom of the sealing rib is tightly against the supporting surface, the water at the bottom of the washing chamber can only try to overflow from the top of the lap edge, and the small amount of water that overflows will fill in the groove of the sealing rib when passing through the sealing rib, forming a water seal on the one hand, and on the other hand, the sealing rib that is slightly deformed under the extrusion force will enhance the locking force between the lap edge and the holding surface at the periphery of the sealing rib under the transmission of the metal part force, ensuring that water cannot overflow from here.

[0020] Preferably, the inner side wall of the base is inclined from bottom to top near the top to form an inclined wall, and the inner side wall of the base located above the inclined wall extends vertically. Correspondingly, the upper part of the side connecting plate matches and fits tightly with the inclined wall and the structure thereon, and the vertical part of the L-shaped structure is accommodated in the missing area formed above the inclined wall. In the assembled state, the inner wall surface of the vertical part of the L-shaped structure corresponds to the inner wall surface of the side connecting plate up and down. This structure extends the overflow path, which can further improve the sealing performance. At the same time, the bottom wall of the washing chamber after assembly is relatively flat and beautiful, which is convenient for the upward sprayed water to flow back downward.

[0021] In the utility model, the side connecting plate on the front side of the bottom plate of the inner tank encloses a water storage cavity for accumulating washing water flowing down from the front door body when the cleaning machine door is in the state, and the end of the water storage cavity in the lateral direction protrudes out of the washing cavity to form a reflux area corresponding to the corner of the door body. When the door body is closed, the water hitting the inner wall of the door body flows back downward, and the water at the bottom of the washing cavity will also surge back and forth toward the door body, which makes it easy to leak water here. The above-mentioned reflux area is provided for the reflux of accumulated water, which can largely avoid water leakage.

[0022] Preferably, the inner part of the front end of the assembly ring extends downward and is inserted into the reflux area to form a guide column. In the closed state, the guide column contacts and seals with the sealing gasket at the bottom of the door body, and a reflux channel is formed between the lower end of the guide column and the bottom wall of the reflux area to connect the reflux area with the washing chamber. The guide column can improve the compactness of the assembly between the assembly ring and the bottom plate of the inner tank, and avoid overflow of water at the joint between the assembly ring and the bottom plate of the inner tank. On the other hand, the formed reflux channel can guide the return water at the corner of the door body and the corner of the washing chamber in an orderly manner, and avoid water leakage at the corner of the door body.

[0023] Preferably, a slot is formed at the top of the assembly ring near the inner wall for inserting the lower edge of the side plate of the inner container body. This structure facilitates the matching and installation of the bottom of the inner container body with the assembly ring.

[0024] Further preferably, the lower edge of the side plate of the inner liner body is at least partially bent outward and upward to form a sealing edge with a U-shaped cross section, and the closed end of the bottom of the U-shaped structure abuts against the inner bottom of the slot. This structure improves the strength of the bottom edge of the metal inner liner body on the one hand, and increases the sealing reliability between the bottom of the inner liner body and the assembly ring on the other hand.

[0025] Preferably, the portion of the assembly ring located at the periphery of the slot is close to the side plate of the liner body and extends upward to form an outer support wall. This structure can improve the overall reliability of the assembly ring and the liner body after assembly.

[0026] In the utility model, the base, the liner bottom plate, the assembly ring and the liner body are locked and connected at the contact points through locking pieces.

[0027] Preferably, a threaded column extending upward is provided on the supporting surface, and correspondingly, a first connecting hole that passes through the upper and lower parts and is used for the threaded column to pass through is provided on the overlapping edge, and a second connecting hole that passes through the upper and lower parts and corresponds to the threaded column is provided on the outer portion of the assembly ring, and the screw passes through the second connecting hole and the threaded column from top to bottom to lock and connect the assembly ring, the overlapping edge and the base.

[0028] Preferably, the side plate of the inner liner body is provided with a third connecting hole near the bottom, and correspondingly, the vertically arranged outer portion of the assembly ring is provided with a fourth connecting hole, and screws pass through the third connecting hole and the fourth connecting hole to lock the assembly ring and the inner liner body.

[0029] A cleaning machine comprises the above-mentioned inner tank assembly, wherein the inner tank assembly is provided with at least one spray arm for spraying a water column, and the inner tank assembly is provided with a front opening and a door body capable of opening or closing the opening.

[0030] Compared with the prior art, the advantages of the present invention are: in order to retain the plastic base and the metal washing chamber, the present invention uses metal material to make the inner tank main body, and divides the base assembly into relatively independent plastic base, metal inner tank bottom plate, and plastic assembly ring. The base provides support for the inner tank assembly, and the metal inner tank main body and the inner tank bottom plate are assembled and constrained on the base through the plastic assembly ring to form a whole. Not only are the various parts easy to produce and manufacture, the metal inner tank bottom plate provides good diversion and drying effects, and the various parts are easy to assemble, which is conducive to reducing production difficulty and cost.

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0038] like Figures 1 to 6 As shown, the inner tank assembly for the washing machine of this embodiment includes an inner tank body 1 and a base assembly 2. The inner tank body 1 includes a metal top plate 11 and side plates 12. The side plates 12 may include three side plates on the left side, the back side, and the back side. The top plate 11 and the side plates 12 together enclose a cavity with a lower opening 13. The base assembly 2 is connected to the bottom of the inner tank body 1 to cover the opening 13 to form a complete washing cavity 10.

[0039] In this embodiment, the base assembly 2 includes a base 21, an inner tank bottom plate 22, and an assembly ring 23. The base 21 is made of plastic material and supported under the inner tank body 1; the inner tank bottom plate 22 is made of metal material, and the edge of the inner tank bottom plate 22 is mounted on the top of the base 21. The inner tank bottom plate 22 covers the lower end opening 13 of the inner tank body 1 and encloses a complete washing chamber 10 with the inner tank body 1; the assembly ring 23 is made of plastic material and clamped between the bottom of the inner tank body 1 and the top of the base 21. The assembly ring 23 forms a first sealing structure sealed with the inner tank bottom plate 22 and a second sealing structure sealed with the bottom edge of the inner tank body 1.

[0040] The edge of the liner bottom plate 22 extends upward to form a side connecting plate 221, and the top edge of the side connecting plate 221 extends outward to form an overlapped edge 222. The top of the base 21 forms a supporting surface 211 on which the overlapped edge 222 is mounted. The bottom of the assembly ring 23 forms a holding surface 231 that abuts against the upper surface of the overlapped edge 222. The holding surface 231 and the supporting surface 211 clamp the overlapped edge 222. The above structure constitutes a first sealing structure. In this way, the upper and lower metal parts are connected together by using the plastic assembly ring 23, which is convenient for the production and assembly of various components.

[0041] The supporting surface 211 is provided with a convex catch 2111 extending upward, and correspondingly, the overlapping edge 222 is provided with a bayonet 2221 which passes through the convex catch 2111, and the pressing surface 231 is provided with a slot 2311 for the convex catch 2111 to be buckled therein. When the base 21, the liner bottom plate 22, and the assembly ring 23 are assembled, the matching structure of the convex catch 2111, the bayonet 2221, and the slot 2311 can realize the pre-positioning of each component to facilitate the subsequent locking and fixing.

[0042] The cross section of the bottom of the assembly ring 23 is formed into an inverted L-shaped structure, which is covered at the junction of the side connecting plate 221 and the overlapping edge 222. The horizontal part 232 of the L-shaped structure is pressed on the overlapping edge 222, and the vertical part 233 of the L-shaped structure is arranged close to the inner wall of the side connecting plate 221. This structure is conducive to improving the compactness and sealing of the assembly between the components.

[0043] The overlapping edge 222 is partially arched downward near the corner 234 of the L-shaped structure to form a sealing rib 235, which is a closed-loop structure arranged circumferentially around the corner 234 of the L-shaped structure. The sealing rib 235 is formed by partially pressing the metal overlapping edge 222 downward, or by other means. This structure can further improve the sealing between the assembly ring 23 and the inner tank bottom plate 22 to prevent hot water or high-temperature steam from overflowing.

[0044] The cross section of the sealing rib 235 is a trapezoidal structure or a V-shaped structure or a bowl-shaped structure with a large upper part and a small lower part. The present embodiment adopts a trapezoidal structure, and the bottom of the sealing rib 235 is pressed and sealed with the supporting surface 211. When the holding surface 231 presses the sealing rib 235 against the supporting surface 211, the metal lap edge 222 located at the periphery of the sealing rib 235 maintains a tendency to press upward against the holding surface 231. Since the bottom of the sealing rib 235 is tightly against the supporting surface 211, the water at the bottom of the washing chamber 10 can only try to overflow from the top of the lap edge 222, and the small amount of water overflowing outward will fill in the groove of the sealing rib 235 when passing through the sealing rib 235, forming a water seal on the one hand, and on the other hand, the sealing rib 235 that is slightly deformed under the extrusion force will enhance the locking force between the lap edge 222 and the holding surface 231 at the periphery of the sealing rib 235 under the transmission of the metal part force, ensuring that water cannot overflow from here.

[0045] The inner side wall of the base 21 is inclined from bottom to top and outward near the top to form an inclined wall 212. The inner side wall of the base 21 located on the inclined wall 212 extends vertically. Correspondingly, the upper part of the side connecting plate 221 matches and fits tightly with the inclined wall 212 and the structure thereon. The vertical part 233 of the L-shaped structure is accommodated in the missing area 2331 formed on the inclined wall 212. In the assembled state, the inner wall surface of the vertical part 233 of the L-shaped structure corresponds to the inner wall surface of the side connecting plate 221 in the upper and lower directions. This structure extends the overflow path, can further improve the sealing performance, and at the same time, makes the bottom wall of the washing chamber 10 relatively flat and beautiful after assembly, which is convenient for the upward sprayed water to flow back downward.

[0046] In this embodiment, the side connecting plate 221 on the front side of the inner tank bottom plate 22 encloses a water storage chamber 101 for accumulating washing water flowing down from the front door body when the cleaning machine door is in the state, and the end of the water storage chamber 101 in the lateral direction protrudes out of the washing chamber 10 to form a reflux area 102 corresponding to the corner of the door body. When the door body is closed, the water hitting the inner wall of the door body flows back downward, and the water at the bottom of the washing chamber 10 will also flow back and forth toward the door body, which makes it easy to leak water here. The above-mentioned reflux area 102 is provided for the reflux of accumulated water, which can largely avoid water leakage.

[0047] The inner part of the front end of the assembly ring 23 extends downward and is inserted into the reflux area 102 to form a guide column 236. In the closed state, the guide column 236 contacts and seals with the sealing gasket at the bottom of the door body, and a reflux channel 103 is formed between the lower end of the guide column 236 and the bottom wall of the reflux area 102 to connect the reflux area 102 with the washing chamber 10. The guide column 236 can improve the compactness of the assembly between the assembly ring 23 and the inner tank bottom plate 22, and avoid overflowing at the joint of the assembly ring 23 and the inner tank bottom plate 22. On the other hand, the formed reflux channel 103 can orderly guide the return water at the matching corner of the door body and the corner of the washing chamber 10, and avoid water leakage at the door body corner.

[0048] The top of the assembly ring 23 is formed with a slot 237 near the inner wall for inserting the lower edge of the side plate of the liner body 1. This structure facilitates the installation of the bottom of the liner body 1 in coordination with the assembly ring 23. The above structure constitutes a second sealing structure. The lower edge of the side plate of the liner body 1 is at least partially bent outward and upward to form a sealing edge 14 with a U-shaped cross-section, and the closed end of the bottom of the U-shaped structure abuts against the inner bottom of the slot 237. This structure improves the strength of the bottom edge of the metal liner body 1 on the one hand, and increases the sealing reliability between the bottom of the liner body 1 and the assembly ring 23 on the other hand.

[0049] The portion of the assembly ring 23 located outside the slot 237 is close to the side plate of the liner body 1 and extends upward to form an outer support wall 238. This structure can improve the overall reliability of the assembly ring 23 and the liner body 1 after partial assembly.

[0050] In this embodiment, the base 21, the liner bottom plate 22, the assembly ring 23, and the liner body 1 are locked and connected at the contact points by locking pieces.

[0051] Specifically, a threaded column 2112 extending upward is provided on the supporting surface 211, and correspondingly, the overlapping edge 222 is provided with a first connecting hole 100 that passes through from top to bottom and for the threaded column 2112 to pass through, and the outer portion of the assembly ring 23 is provided with a second connecting hole 200 that passes through from top to bottom and corresponds to the threaded column 2112. The screws pass through the second connecting hole 200 and the threaded column 2112 from top to bottom to lock and connect the assembly ring 23, the overlapping edge 222, and the base 21.

[0052] The side plate 12 of the inner tank body 1 is provided with a third connecting hole 300 near the bottom, and correspondingly, the vertically arranged outer portion of the assembly ring 23 is provided with a fourth connecting hole 400, and screws pass through the third connecting hole 300 and the fourth connecting hole 400 to lock the assembly ring 23 and the inner tank body 1.

[0053] The cleaning machine of this embodiment includes the above-mentioned inner tank assembly, in which at least one spray arm for spraying water is provided, and the inner tank assembly is provided with a front opening and a door body capable of opening or closing the opening.

[0054] When assembling the liner assembly of this embodiment, the base 21 is supported on the assembly table, the liner bottom plate 22 is mounted on the base 21, and the threaded column 2112 and the convex card 2111 pass through the overlapping edge 222 to pre-position the liner bottom plate 22, and then the assembly ring 23 is placed on the base 21 and the overlapping edge 222, and the top of the convex card 2111 is inserted into the card slot 2311 to constrain the base 21, the liner bottom plate 22, and the assembly ring 23 together. At this time, the screws are passed from top to bottom through the second connecting hole 200 and the threaded column 2112 to lock the assembly ring 23, the overlapping edge 222, and the base 21 together; then the lower end of the liner body 1 is inserted into the slot 237, and the screws are passed through the third connecting hole 300 and the fourth connecting hole 400 to lock the assembly ring 23 and the liner body 1 together.

[0055] In order to retain the plastic base and the metal washing chamber, the present embodiment uses a metal material to make part of the inner tank body 1, and divides the base assembly 2 into a relatively independent plastic base 21, a metal inner tank bottom plate 22, and a plastic assembly ring 23. The base 21 provides support for the inner tank assembly, and the metal inner tank body 1 and the inner tank bottom plate 22 are assembled and constrained on the base through the plastic assembly ring 23 to form a whole. Not only are the various parts easy to produce and manufacture, the metal inner tank bottom plate 22 provides good diversion and drying effects, and the various parts are easy to assemble, which helps to reduce production difficulty and cost.
