Description

Technical Field

[0001] The invention relates to a washing machine capable of washing tableware and / or fruits and vegetables, and in particular to a shelf assembly used for the washing machine and the washing machine. Background Art

[0002] The capacity of current washing machines, such as sink-type dishwashers (open top), is getting bigger and bigger, and the fruit and vegetable baskets are also getting bigger and bigger. When the fruits and vegetables are not being washed, they are too large to be stored and are easily lost. In addition, in order to facilitate the placement and washing of tableware, the current dishwashers only have one large basket in the washing chamber, which makes it difficult to place some living foods for washing. As a result, the washing objects that can be washed by the dishwasher are relatively single and inconvenient.

[0003] In response to the above problems, the Chinese utility model patent with patent number CN201920548274.2 (publication number CN210158560U) discloses "Fruit and Vegetable Basket and Dishwasher", which has a fruit and vegetable base basket with a first accommodating cavity and a basket cover detachably covered on the first accommodating cavity, the bottom surface of the basket cover is buckled on the side wall of the first accommodating cavity and is enclosed with the first accommodating cavity to form a washing space for placing washes; and a first accommodating rack is provided in the washing basket, the fruit and vegetable base basket is placed on the first accommodating rack after being buckled with the basket cover, and a second accommodating rack is arranged side by side on one side of the first accommodating rack in the washing basket, and the basket cover is inverted and placed on the first accommodating rack and the second accommodating rack respectively with the fruit and vegetable base basket.

[0004] Regardless of the usage state of the fruit and vegetable basket of this patent, the items inside the basket are cleaned by the spray device in the cavity of the dishwasher, which easily leads to dead corners in cleaning. Summary of the invention

[0005] The first technical problem to be solved by the present invention is to provide a shelf assembly for a cleaning machine with fewer cleaning dead corners in view of the current status of the prior art.

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

[0007] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a shelf assembly for a washing machine, comprising a shelf, wherein the shelf comprises two basket bodies each having an open opening on one side, each of the basket bodies having a drain hole, and the shelf having a first use state and a second use state, wherein when the shelf is in the first use state, the openings of the two basket bodies are matched to form a closed accommodating space, and when the shelf is in the second use state, the two basket bodies are arranged side by side and both of the openings face upward;

[0008] It is characterized in that at least one of the side walls of the basket is provided with a spray hole for water to pass through, the shelf also includes a water pipe connected to the spray hole, and when the shelf is in a first use state, the shelf can rotate around a rotation axis extending horizontally or vertically.

[0009] In order to further reduce the cleaning dead angle, the side walls of the two baskets are provided with spray holes, and correspondingly, there are two water pipes, so that water can flow directly through the two baskets, and there are fewer cleaning dead angles in the two baskets.

[0010] Preferably, the water pipe extends along the circumference of the corresponding basket body, and each basket body has a plurality of spray holes spaced along its circumferential wall, and the water pipe is provided with through holes corresponding to and connected to the spray holes. In this way, water can enter multiple places in the basket body, further reducing cleaning dead corners.

[0011] Both water pipes can be connected to the water source, but this is a more complicated structure, so one of the water pipes is connected to the water source, and when the rack is in the second use state, the two water pipes are connected. When the rack is in the first use state, because the rack can rotate, as long as one of the baskets is filled with water, the cleaning dead angle can be reduced; because the basket is fixed when the rack is in the second use state, water is filled in both baskets, so that the cleaning dead angles in both baskets are reduced.

[0012] In order to make the two water pipes connected or disconnected, the two water pipes are respectively a first water pipe and a second water pipe. The first water pipe is connected to a water source, a first water hole is provided on the first water pipe, and a second water hole is provided on the second water pipe. A valve structure that can open or close the first water hole is provided at the first water hole. When the shelf is in the second usage state, the first water hole and the second water hole correspond to each other, and the valve structure opens the first water hole; when the shelf is in the first usage state, the first water hole and the second water hole are disconnected, and the valve structure closes the first water hole.

[0013] The valve structure may have a variety of structural forms, such as an existing solenoid valve, but the cost is relatively high. The valve structure includes a plug and a first elastic member, and the first elastic member acts on the plug to keep the plug closing the first water hole;

[0014] The portion of the second water pipe that surrounds the second water hole forms a push rod, which can be detachably inserted into the first water hole. When the shelf is in the second use state, the push rod abuts against the plug and pushes the plug away and opens the first water hole. When the shelf is in the first use state, the push rod is removed from the first water hole. When the shelf is in the second use state, the first water hole and the second water hole correspond to each other, the push rod is inserted into the first water hole and pushes the plug, so that the first water hole is opened, and water is connected between the two water pipes. A part of the water in the first water pipe is sprayed out from the spray hole connected to it, and the other part enters the second water pipe and sprays out from the spray hole corresponding to the second water pipe. When the shelf is transformed from the second use state to the first use state, the push rod is removed from the first water hole, and the plug blocks the first water hole. At this time, water is sprayed only from the spray hole corresponding to the first water pipe.

[0015] In order to ensure that the two basket bodies can be relatively fixed when the shelf is in the first usage state or the second usage state, each of the basket bodies includes a first side edge and a second side edge that are relatively arranged and a third side edge connecting the first side edge and the second side edge. When the shelf is in the second usage state, the first side edges of the two basket bodies are arranged side by side and adjacent to each other, and the second side edges of the two basket bodies are far away from each other. When the shelf is in the first usage state or the second usage state, the third side edges of the two basket bodies located on the same side are relatively fixed by positioning pieces.

[0016] The positioning member can have a variety of structural forms, such as screws, but it is troublesome to remove and install screws when switching the use state of the shelf, so the longitudinal section of the positioning member is U-shaped, and the third side edges of the two baskets on the same side can be detachably embedded in the U-shaped groove of the positioning member. In this way, the positioning member can be separated from the basket by simply pulling out the positioning member; the third side edge of the basket is embedded in the U-shaped groove of the positioning member, that is, the two baskets are relatively positioned through the positioning member.

[0017] Because the shelf needs to be rotated when in the first use state, in order to ensure the relative stability of the two baskets in this state, a rotation structure and a connection structure are provided between the two baskets. When the shelf is in the first use state, the first sides of the two baskets are rotatably connected through the rotation structure, and the second sides of the two baskets are detachably connected through the connection structure. When the shelf needs to be switched from the first use state to the second use state, the connection structure is released from the positioning of the two baskets, and then one of the baskets is rotated.

[0018] The rotating structure can have various structural forms. Preferably, the rotating structure includes a rotating shaft and a limiting portion, the rotating shaft and the limiting portion are respectively arranged at the first side edges of the two basket bodies, the rotating shaft extends along the length direction of the first side edge, the limiting portion is in an arc shape that arches upward in the direction away from the rotating shaft, and the rotating shaft is located in the arc region of the limiting portion and can rotate around its axis.

[0019] The connection structure can have a variety of structural forms, such as a magnetic attraction method, and the structure is simple. The connection structure includes a buckle groove arranged at the second side of one of the basket bodies and a buckle foot arranged at the second side of the other basket body, and the buckle foot can be detachably buckled in the buckle groove.

[0020] Preferably, a convex portion is provided at the first side edge of one of the basket bodies, and a slot is provided on the convex portion. When the shelf is in the second use state, the second side edge of the other basket body can be detachably embedded in the slot of the convex portion, thereby improving the relative stability of the two basket bodies.

[0021] In the above solution, the two baskets can be separated, and the shelf also has a third use state, in which one basket is embedded in the other basket. When fruits and vegetables do not need to be washed, the two baskets can be used as drain baskets separately, and the two baskets can be stacked together to reduce storage space.

[0022] The technical solution adopted by the present invention to solve the above second technical problem is: a cleaning machine, characterized in that it includes a box body and the above shelf, the top or side of the box body is open, and the shelf is arranged in the box body.

[0023] In order to position the shelf relative to the box body, two opposite sides of one of the basket bodies are provided with limiting members, and the box body is correspondingly provided with a supporting member on which the limiting member is positioned.

[0024] In the above solution, the limiting member extends in the horizontal direction, and when the shelf is in the first use state, the shelf can rotate around the limiting member as an axis.

[0025] In the above solution, the two limit members are respectively a first limit member and a second limit member, and the two support members are respectively a first support member matched with the first limit member and a second support member matched with the second limit member;

[0026] The first support member is tubular and serves as a water supply pipe, and is provided with a water outlet in the box body. The first limiting member is arranged on the water pipe of the corresponding basket body, and is provided with a water inlet connecting the water outlet and the corresponding water pipe to realize the connection between the water pipe and the water source.

[0027] Preferably, the first support member and the second support member each have at least two at different heights, and correspondingly, the first limiter and the second limiter each have at least two at different heights, and the first limiter can be detachably positioned on the first support member at different heights, and the second limiter can be detachably positioned on the second support member at different heights. This makes it easy to position the shelf at different heights in different usage states, so that users can easily take items from the shelf.

[0028] In order to realize the disassembly and assembly of the limiting member and the corresponding supporting member, a first limiting column is movably provided in the water outlet of the first supporting member, and a water passage for water to flow through is provided on the first limiting column. The first limiting column can be inserted into the water inlet of the first limiting member or detached from the water inlet. The first limiting column maintains a tendency to be inserted into the water inlet under the action of the second elastic member;

[0029] The second limiting member is provided with an insertion hole, and the second supporting member is movably provided with a second limiting column, the second limiting column can be inserted into the insertion hole of the second limiting member or detached from the insertion hole, and the second limiting column maintains a tendency to be inserted into the insertion hole under the action of the third elastic member.

[0030] Compared with the prior art, the advantages of the present invention are as follows: the present invention provides a spray hole for water to pass through on the side wall of at least one of the basket bodies, and the shelf also includes a water pipe connected to the spray hole, so that the water pipe can pass water into the spray hole, so that the water flows directly into the basket body. Compared with the cleaning method that only relies on the spray arm located outside the basket body, this spraying method of the present invention can reduce the cleaning dead angle, and when the shelf is in the first use state, the shelf can rotate around a rotation axis extending horizontally or vertically, which can further reduce the cleaning dead angle.

[0046] The present invention is further described in detail below with reference to the accompanying drawings.

[0047] like Figures 1 to 15 As shown, the cleaning machine of this preferred embodiment includes a box body 1 and a shelf assembly. The top or side of the box body 1 is open, and the shelf is arranged in the box body 1. In this embodiment, the shelf can be used to place tableware such as bowls and plates, pots and pans, and fruits and vegetables. The box body 1 has two and both have open tops. Figure 1 The box 1 on the left side is used as a common sink. Figure 1 The interior of the box body 1 on the middle right side is provided with a spray arm, and can be used as a dishwasher.

[0048] The shelf assembly comprises a shelf, and the shelf comprises two basket bodies 2 each having an opening 21 on one side, and each basket body 2 has a drainage hole 20. The shelf has a first use state, a second use state and a third use state.

[0049] like Fig.12 , 13As shown, when the shelf is in the first use state, the openings 21 of the two basket bodies 2 are matched to form a closed accommodating space, and in this state the shelf can rotate around a rotation axis extending horizontally or vertically. In this embodiment, the shelf rotates around a rotation axis extending horizontally. This situation is suitable for relatively dirty and difficult to clean items.

[0050] like Figure 2 , 3 As shown, when the shelf is in the second use state, the two basket bodies 2 are arranged side by side and both openings 21 face upwards. This situation is suitable when the number of items to be washed is large.

[0051] The two baskets 2 can be separated, such as Fig.15 As shown, when the rack is in the third use state, one basket body 2 is embedded in the other basket body 2. This situation is suitable when there is no need to wash fruits, vegetables, tableware, etc., and the two basket bodies 2 can be used as drain baskets separately, and the two basket bodies 2 can be stacked together to reduce storage space.

[0052] In this embodiment, when the shelf is in the first use state and the second use state, the shelf is suitable for being placed Figure 1 In the box 1 on the right side of the middle; when the shelf is in the third use state, the shelf is suitable for being placed Figure 1 In the box 1 on the left side.

[0053] like Figure 2 As shown, each basket body 2 includes a first side 2a, a second side 2b and a third side 2c, the first side 2a and the second side 2b are arranged opposite to each other, the third side 2c has two oppositely arranged sides, one end of the first side 2a and one end of the second side 2b are connected through one of the third sides 2c, and the other end of the first side 2a and the other end of the second side 2b are connected through another third side 2c.

[0054] When the shelf is in the second use state, the first side edges 2a of the two basket bodies 2 are arranged side by side and adjacent to each other, the second side edges 2b of the two basket bodies 2 are far away from each other, and the extension direction of the third side edges 2c of the two basket bodies 2 located on the same side is located on the same straight line. When the shelf is in the first use state or the second use state, the third side edges 2c of the two basket bodies 2 located on the same side are relatively fixed by the positioning member 3. The longitudinal section of the positioning member 3 is U-shaped, and the third side edges 2c of the two basket bodies 2 located on the same side are detachably embedded in the U-shaped groove of the positioning member 3. In this way, the positioning member 3 can be separated from the basket body 2 by simply pulling out the positioning member 3; the third side edge 2c of the basket body 2 is embedded in the U-shaped groove of the positioning member 3, that is, the two basket bodies 2 are relatively positioned by the positioning member 3.

[0055] Because the shelf needs to be rotated when in the first use state, in order to ensure the relative stability of the two basket bodies 2 in this state, a rotating structure and a connecting structure are further provided between the two basket bodies 2. When the shelf is in the first use state, the first side edges 2a of the two basket bodies 2 are rotatably connected via the rotating structure, and the second side edges 2b of the two basket bodies 2 are detachably connected via the connecting structure.

[0056] like Fig.13 , 14 As shown, the rotating structure includes a rotating shaft 22 and a limiting portion 23. The rotating shaft 22 and the limiting portion 23 are respectively arranged at the first side edges 2a of the two basket bodies 2. The rotating shaft 22 extends along the length direction of the first side edge 2a. The limiting portion 23 is in an arc shape that arches upward in a direction away from the rotating shaft 22. The rotating shaft 22 is located in the arc region of the limiting portion 23 and can rotate around its axis. Because the limiting portion 23 is in an arc shape, rather than a closed circle, the limiting portion 23 can only prevent the rotating shaft 22 from falling off within a certain range. The rotating shaft 22 can fall off from the notch of the limiting portion 23 to achieve the separation of the two basket bodies 2.

[0057] The connection structure includes a buckle groove 24 provided at the second side 2b of one of the basket bodies 2 and a buckle foot 25 provided at the second side 2b of the other basket body 2, and the buckle foot 25 is detachably buckled in the buckle groove 24. When the shelf needs to be switched to the second use state, the buckle foot 25 is removed from the buckle groove 24, and then one of the basket bodies 2 is rotated.

[0058] In addition, if Figure 7 As shown, a convex portion 26 is provided at the first side edge 2a of one of the basket bodies 2, and a slot 261 is provided on the convex portion 26. When the shelf is in the second use state, the second side edge 2b of the other basket body 2 can be detachably embedded in the slot 261 of the convex portion 26, thereby improving the relative stability of the two basket bodies 2.

[0059] As can be seen from the above, in this embodiment, the relative positioning between the two basket bodies 2 when the shelf is in the first use state and the second use state is achieved through the positioning member 3, the rotating structure, the connecting structure, etc.

[0060] A spray arm 7 is provided at the bottom of the box body 1. The spray arm 7 can adopt an existing structure. The spray arm 7 is located below the shelf. However, if water is sprayed only by the spray arm 7, there is a dead corner for cleaning. Therefore, a spray hole 27 for water to pass through is provided on the side wall of at least one of the basket bodies 2. The shelf also includes a water pipe connected to the spray hole 27 to pass water directly from the spray hole 27 into the basket body 2.

[0061] In this embodiment, the side walls of the two basket bodies 2 are provided with spray holes 27, and correspondingly, there are two water pipes. The water pipes extend along the circumference of the corresponding basket body 2, and there are multiple spray holes 27 on each basket body 2 arranged at intervals along its circumferential wall, and the water pipes are provided with through holes 40 corresponding to the spray holes 27. In this way, water can enter multiple places in the basket body 2, further reducing the cleaning dead corners.

[0062] One of the water pipes is connected to the water source, and when the rack is in the second use state, the two water pipes are connected. When the rack is in the first use state, because the rack can rotate, as long as water flows through one of the baskets 2, the cleaning dead angle can be reduced. In this state, the rack can be driven to rotate by the motor, and the rack can also be rotated under the impact of the water in the basket 2; because the basket 2 is fixed when the rack is in the second use state, water flows through both baskets 2, so that the cleaning dead angles in the two baskets 2 are reduced.

[0063] In order to make the two water pipes connected or disconnected, Figure 5 As shown, the two water pipes are respectively a first water pipe 41 and a second water pipe 42. The first water pipe 41 is connected to a water source. The first water pipe 41 is provided with a first water hole 411, and the second water pipe 42 is provided with a second water hole 421. The first water hole 411 is provided with a valve structure that can open or close it. When the shelf is in the second use state, the first water hole 411 and the second water hole 421 correspond to each other, and the valve structure opens the first water hole 411; when the shelf is in the first use state, the first water hole 411 and the second water hole 421 are disconnected, and the valve structure closes the first water hole 411.

[0064] The valve structure includes a plug 43 and a first elastic member 44. The first elastic member 44 acts on the plug 43 so that the plug 43 maintains a tendency to close the first water hole 411. In this embodiment, the first elastic member 44 is a spring, one end of which is against the plug 43 and the other end is against the wall of the first water hole 411.

[0065] The portion of the second water passage pipe 42 that surrounds the second water passage hole 421 forms a push rod 45, and the push rod 45 can be detachably inserted into the first water passage hole 411. When the shelf is in the second use state, the push rod 45 abuts against the plug 43 and pushes the plug 43 away from and opens the first water passage hole 411. The first water passage hole 411 and the second water passage hole 421 correspond to each other. The push rod 45 is inserted into the first water passage hole 411 and pushes the plug 43, so that the first water passage hole 411 is opened, and water is connected between the two water passage pipes. A part of the water in the first water passage pipe 41 is sprayed out from the spray hole 27 connected to it, and the other part enters the second water passage pipe 42 and is sprayed out from the spray hole 27 corresponding to the second water passage pipe 42, that is, water enters both basket bodies 2.

[0066] When the shelf is in the first use state, the top rod 45 is disengaged from the first water hole 411. When the shelf is changed from the second use state to the first use state, the top rod 45 is disengaged from the first water hole 411, and the plug 43 blocks the first water hole 411. At this time, water is only sprayed from the spray hole 27 corresponding to the first water pipe 41.

[0067] In order to position the shelf relative to the box body 1, two opposite sides of one of the basket bodies 2 are provided with stoppers, and a support member for the stoppers to be positioned is correspondingly provided in the box body 1. In this embodiment, the stoppers are arranged at the third side 2c of the basket body 2. The stoppers extend in the horizontal direction, and when the shelf is in the first use state, the shelf can rotate with the stoppers as the axis.

[0068] like Fig.10 , 11 As shown, the two stoppers are respectively a first stopper 51 and a second stopper 52, and the two support members are respectively a first support member 61 matched with the first stopper 51 and a second support member 62 matched with the second stopper 52, wherein the first support member 61 is tubular as a water supply pipe, and the first support member 61 is provided with a water outlet 611 located in the box body 1, the first stopper 51 is provided on the water pipe corresponding to the basket body 2, and the first stopper 51 is provided with a water inlet 511 communicating with the water outlet 611 and the corresponding water pipe. In this embodiment, the first stopper 51 is provided on the first water pipe 41.

[0069] Each of the first support members 61 and the second support members 62 has at least two at different heights. Correspondingly, each of the first limiting members 51 and the second limiting members 52 also has at least two at different heights. The first limiting member 51 can be detachably positioned on the first support members 61 at different heights, and the second limiting member 52 can be detachably positioned on the second support members 62 at different heights. This makes it easy to position the shelf at different heights under different usage conditions, which is convenient for users to take items from the shelf and prevents interference between the shelf and the spray arm 7.

[0070] like Fig.11 As shown, a first limiting column 7 is movably provided in the water outlet 611 of the first support member 61, and the first limiting column 7 can be inserted into the water inlet 511 of the first limiting member 51 or detached from the water inlet 511. The first limiting column 7 maintains the tendency of being inserted into the water inlet 511 under the action of the second elastic member 71, and a water passage for water to flow through is provided on the first limiting column 7, so that water can flow through. The second elastic member 71 can be a spring, one end of which is against the first limiting column 7, and the other end is against the wall surface of the water inlet 511.

[0071] like Fig.10As shown, the second limiting member 52 is provided with an insertion hole 521, and the second supporting member 62 is movably provided with a second limiting column 8, the second limiting column 8 can be inserted into the insertion hole 521 of the second limiting member 52 or detached from the insertion hole 521, and the second limiting column 8 maintains the tendency of being inserted into the insertion hole 521 under the action of the third elastic member 81. The third elastic member 81 can be a spring, one end of which is against the second limiting column 8, and the other end is against the wall surface of the insertion hole 521.

[0072] When it is necessary to disassemble the limit member, force is applied to the limit member, and the limit column is forced to move in the direction away from the limit member, so as to realize the disassembly of the limit member; when it is necessary to install the limit member, force is applied to the limit member, and the limit column is forced to move in the direction away from the limit member first, and when the socket of the limit member is aligned with the limit column, the limit column is inserted into the socket under the action of the second elastic member, so as to realize the assembly of the limit member and the support member. The end of the limit column inserted into the socket is designed to be conical, so as to facilitate the assembly or disengagement of the limit member and the limit column. In this paragraph, "limit column" refers to "first limit column 7" or "second limit column 8", and the limit member corresponds to the corresponding limit column.

[0073] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are 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. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
