Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and in particular relates to a washing machine capable of washing dishes and / or fruits and vegetables. Background Art

[0002] A washing machine is a device that sprays cold or hot water onto dishes to remove dirt adhered to the dishes and wash the dishes. A general washing machine includes a spray arm that sprays washing water, a heater that generates hot water, and the like.

[0003] During the cleaning process of the washing machine, in order to obtain a better cleaning effect, it is necessary to add detergents such as dishwashing blocks and dishwashing powder. Therefore, it is generally necessary to install a detergent dispensing structure in the washing machine, such as the structure disclosed in the utility model patent "Dispenser structure, door assembly and dishwasher" with patent number ZL202122290832.X (authorization announcement number CN215820855U), which includes a dispenser body with a first dispensing part and a second dispensing part. The second dispensing part mainly includes a groove-shaped second dispensing groove and a second sealing cover for opening and closing. The second dispensing groove is mainly used to place washing materials such as dishwashing powder. The second sealing cover is opened and closed by sliding on the notch of the second dispensing groove. The second sealing cover can be opened to place the washing materials into the second dispensing groove before washing, and the washing materials can be dispensed out at a specified time during the washing process.

[0004] In the prior art, in order to allow the washing materials in the second delivery slot to fall into the housing of the washing machine as completely as possible and prevent the washing materials from adhering to the inner wall surface of the second delivery slot, the second delivery slot is generally flushed by spraying washing water. However, since the second delivery slot in the above patent is embedded in the mounting seat of the second delivery part, it is difficult for the washing water to flush the inner wall surface of the second delivery slot. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a cleaning machine for flushing the delivery structure with washing water in view of the current status of the prior art.

[0006] The technical solution adopted by the utility model to solve the above-mentioned first technical problem is: a cleaning machine, comprising:

[0007] The box body is hollow inside and has a cleaning cavity;

[0008] The spray arm is arranged in the box;

[0009] A delivery box is arranged inside the box body and beside the spray arm; the delivery box has a cavity with an open top;

[0010] It is characterized by also including:

[0011] The guide plate is arranged in the box body and above the delivery box. The guide plate has a guide surface extending up and down and facing the spray arm. The lower edge of the guide surface is located just above the opening of the delivery box.

[0012] In this way, the washing water sprayed by the spray arm can directly enter the delivery box through the opening to rinse the delivery box, or it can first be sprayed to the guide surface of the guide plate, flow downward along the guide surface and enter the delivery box through the opening, so that the washing water is collected in the delivery box and rinses the delivery box. At the same time, the design of the guide plate of the utility model can effectively overcome the situation that the sprayed washing water cannot be sprayed directly into the delivery box due to sudden changes in water pressure during use or the mismatch between the installation height of the spray arm and the installation height of the delivery box.

[0013] In order to better collect the sprayed washing water into the delivery box, preferably, the delivery box is located at the front side of the spray arm;

[0014] It also includes a mounting seat, which is arranged on the inner wall of the front side of the box body corresponding to the position of the guide plate and has a mounting groove with the notch facing backwards;

[0015] The guide plate is arranged in the installation groove, and at least the lower part of the guide surface of the guide plate is located at the front side of the slot, and defines a guide groove extending downward with the inner wall of the slot, and the bottom of the guide groove is open and opposite to the opening of the delivery box. Thus, the sprayed washing water flows downward along the guide groove into the delivery box. The side walls of the guide groove located on both sides of the guide plate can play a water blocking role.

[0016] Preferably, the mounting groove extends up and down, and the guide plate is arranged in the mounting groove so as to be movable up and down, and has:

[0017] An open state located above the delivery box, at which the lower edge of the guide surface is located directly above the opening of the delivery box;

[0018] And a closed state shielding the rear side of the delivery box.

[0019] In the closed state, the guide plate blocks the delivery box to prevent the delivery box from being directly exposed in the box. In the open state, the guide plate can play a diversion role, and the open and closed states can be switched by moving the guide plate up and down, which is convenient for operation.

[0020] Furthermore, the delivery box can be movably arranged in the lower space of the mounting slot. When the guide plate is in an open state, the opening of the delivery box faces upward and is at least partially located outside the slot of the mounting slot; when the guide plate is in a closed state, the delivery box is retracted in the mounting slot.

[0021] Furthermore, the delivery box is rotatably disposed in the installation slot, and the rotation axis crosses the slot opening of the installation slot in the left-right direction and is adjacent to the opening of the delivery box;

[0022] When the guide plate is in a closed state, the delivery box is constrained in the installation slot by the action of the guide plate, and the opening of the delivery box is opposite to the plate surface of the guide plate facing away from the spray arm; when the guide plate is in an open state, the delivery box rotates outside the installation slot under the action of its own gravity until the opening faces upward.

[0023] In this way, the delivery box can be switched between two states by moving the guide plate up and down, which is easy to operate.

[0024] In the above schemes, preferably, the left and right sides of the guide plate are provided with bosses, and the side walls of the mounting groove are provided with slide grooves for the corresponding bosses to be inserted therein, and the two slide grooves are arranged opposite to each other, one on the left and one on the right, and both extend up and down.

[0025] Preferably, there are at least two protrusions on the same side of the guide plate, and they are respectively located at the upper and lower ends of the side; the slide groove has two sections, namely a first slide groove and a second slide groove located below the first slide groove, the first slide groove is located at the upper part of the above-mentioned installation groove, and has a first part extending backward from top to bottom in a length direction, and a second part extending downward and forward in a downward direction from the lower end of the first part; the second slide groove is located at the lower part of the above-mentioned installation groove, and has a third part extending downward in a length direction, and a fourth part extending downward and forward in a downward direction from the lower end of the third part;

[0026] When the guide plate is in a closed state, the convex column located at the upper end of the side of the guide plate is located at the lower end of the second part, and the convex column located at the lower end of the side of the guide plate is located at the lower end of the fourth part;

[0027] When the guide plate is in an open state, the convex column located at the upper end of the guide plate side is located at the upper end of the above-mentioned first part, and the convex column located at the lower end of the guide plate side is located at the lower end of the above-mentioned third part.

[0028] In this way, the inclined extended slide groove design facilitates the closing of the guide plate, and can also position the guide plate forward when the guide plate is opened (even if the lower edge of the guide plate is located directly above the delivery box), preventing the guide plate from blocking part of the sprayed washing water and preventing this part of the washing water from entering the delivery box, thereby ensuring that more washing water can directly enter the delivery box.

[0029] Preferably, the inclination angle of the second portion of the first slide groove relative to the vertical plane is greater than the inclination angle of the fourth portion of the second slide groove relative to the vertical plane; the second portion of the first slide groove and the fourth portion of the second slide groove are consistent in length in the up and down directions.

[0030] Furthermore, the length of the fourth portion of the second slide groove in the up-down direction is smaller than the length of the third portion, and the lower end portion of the third portion is arranged corresponding to the bottom position of the portion of the installation groove where the delivery box is located.

[0031] In the above-mentioned schemes, preferably, the spray arm is arranged in a manner that it can rotate around an axis extending up and down.

[0032] Compared with the prior art, the utility model has the advantages that: by setting the guide plate, the washing water sprayed by the spray arm can directly enter the delivery box through the opening to rinse the delivery box, or it can first be sprayed to the guide surface of the guide plate, flow downward along the guide surface and enter the delivery box through the opening, so that the washing water is collected in the delivery box and flushes the delivery box. At the same time, the design of the guide plate of the utility model can effectively overcome the situation that the sprayed washing water cannot be sprayed directly into the delivery box due to sudden changes in water pressure during use or the mismatch between the installation height of the spray arm and the installation height of the delivery box.

[0045] The guide plate 2 extends up and down and is movably disposed in the mounting groove 13 of the mounting seat 1 , and has a closed state in which the front plate surface is opposite to the opening 100 of the accommodating space 10 and closes the opening 100 , and an open state in which the front plate surface is located above the accommodating space 10 and opens the opening 100 .

[0046] The delivery box 3 has a cavity 30 with an opening 300, and a box wall 31 of the delivery box 3 opposite to the opening 300 is provided with a long strip leakage hole 310 penetrating the wall thickness. There are a plurality of leakage holes 310, which are spaced and arranged in parallel along the left-right direction. The delivery box 3 is rotatably arranged in the accommodating space 10, and the rotation axis of the delivery box 3 crosses the opening 100 of the accommodating space 10 in the left-right direction and is adjacent to the position of the opening 300. When the guide plate 2 is in a closed state, the delivery box 3 is constrained in the accommodating space 10 of the mounting seat 1 under the action of the guide plate 2, and the opening 300 of the cavity 30 of the delivery box 3 is opposite to the plate surface on the front side of the guide plate 2; when the guide plate 2 is in an open state, the delivery box 3 rotates out of the opening 100 under the action of its own gravity. At this time, the opening 300 of the cavity 30 of the delivery box 3 faces upward and is partially located outside the opening 100 of the mounting seat 1, and the leakage hole 310 extends along the front-back direction and is partially located outside the opening 100 of the mounting seat 1.

[0047] In this embodiment, the cross section of the box wall 31 of the delivery box 3 opposite to the opening 300 is in the shape of a semicircle, and the center of the arc is located at the rotation axis of the delivery box 3, and the two ends of the arc are located at both sides of the rotation axis of the delivery box 3, and together define the opening 300 of the delivery box 3. The delivery box 3 also has side walls located on the left and right sides of the box wall 31, each of which is in the shape of a semicircle with an arc edge and a straight edge, and the arc edge of the side wall is connected to the corresponding side edge of the box wall 31, and the straight edge of the side wall is located at the opening 300. The delivery box 3 is rotatably constrained at the accommodating space 10 of the mounting seat 1 through the rotating structure on the straight edge of the side wall. Specifically, the center of the straight edge of the side wall of the delivery box 3 is constrained at the opening 100 of the accommodating space 10 through a rotating shaft extending left and right, and the central axis of the rotating shaft is the rotation axis of the delivery box 3.

[0048] In this embodiment, the shape of the inner wall of the accommodating space 10 of the mounting seat 1 is consistent with the shape of the delivery box 3, and has a forwardly concave arc-shaped wall 11, and the upper and lower ends of the arc-shaped wall 11 jointly define an opening 100 of the accommodating space 10. At the same time, a plurality of long strip-shaped pores 110 are provided at the upper end of the arc-shaped wall 11, and each of the long strip-shaped pores 110 is arranged in parallel and spaced apart in the left-right direction.

[0049] When the guide plate 2 is in the open state, the guide plate 2 is located above the delivery box 3, and the plate surface on the rear side of the guide plate 2 is recorded as the guide surface 2a. The guide surface 2a is located in front of the slot of the installation slot 13, and defines a downwardly extending guide slot 101 together with the inner wall of the slot of the installation slot 13. The bottom of the guide slot 101 is open and opposite to the opening 300 of the delivery box 3, so that the washing water sprayed onto the guide surface 2a can flow downward along the guide surface 2a into the delivery box 3. In order to enable the guide plate 2 to switch between the open and closed states, the connection structure between the guide plate 2 and the mounting seat 1 is as follows: the left and right sides of the guide plate 2 are provided with bosses 21, and the mounting seat 1 is provided with a slide 12 for the corresponding boss 21 to be inserted therein, and the two slides 12 are arranged opposite to each other, one left and one right, and both extend up and down. There are two protrusions 21 on the same side of the guide plate 2, and they are respectively located at the upper and lower ends of the side; the chute 12 has two sections, namely a first section chute 12a for inserting the protrusion 21 at the upper end of the side, and a second section chute 12b located below the first section chute 12a and for inserting the protrusion 21 at the lower end of the side. The first section chute 12a is located above the above-mentioned accommodating space 10, and has a first portion 121 extending backward from top to bottom in the length direction, and a second portion 122 extending downward and forward from the lower end of the first portion 121. The second section 122; the second section chute 12b is located beside the accommodating space 10, and has a third section 123 extending vertically downward in the length direction, and a fourth section 124 extending downward and forward from the lower end of the third section 123. The inclination angle of the fourth section 124 of the second section chute 12b relative to the vertical plane is smaller than the inclination angle of the second section 122 of the first section chute 12a relative to the vertical plane. The fourth section 124 of the second section chute 12b and the second section 122 of the first section chute 12a have the same length in the vertical direction. The length of the fourth section 124 of the second section chute 12b in the vertical direction is smaller than the length of the third section 123, and the lower end of the third section 123 corresponds to the bottom position of the opening 100 of the accommodating space 10.

[0050] When the guide plate 2 is in a closed state, the convex column 21 located at the upper end of the side of the guide plate is located at the lower end of the second part 122, and the convex column 21 located at the lower end of the side of the guide plate is located at the lower end of the fourth part 124;

[0051] When the guide plate 2 is in the open state, the boss 21 located at the upper end of the guide plate side is located at the upper end of the first part 121 , and the boss 21 located at the lower end of the guide plate side is located at the lower end of the third part 123 .

[0052] In this way, the design of the inclined extended chute 12 facilitates the closing of the guide plate 2, and when the guide plate 2 is opened, the guide plate 2 is arranged forward (even if the lower edge of the guide plate 2 is located directly above the delivery box 3), preventing the guide plate 2 from blocking part of the sprayed washing water and preventing this part of the washing water from entering the delivery box, thereby ensuring that more washing water can directly enter the delivery box 3. The guide plate 2 in the open state can play a diversion role, so that part of the washing water can flow down along the plate surface on the rear side of the guide plate 2 into the delivery box 3, thereby effectively overcoming the situation that the sprayed washing water cannot be directly sprayed into the delivery box 3 due to a sudden change in water pressure during use or the mismatch between the installation height of the spray arm and the installation height of the delivery box.

[0053] like Figure 7 As shown, the cleaning machine of this embodiment includes a housing 4 , a detergent delivery structure and a spray arm 5 .

[0054] The box body 4 includes a box body 41 with an open opening on the front side, and a door body 42 disposed at the open opening to open and close the open opening. Specifically, the door body 42 is disposed at the open opening of the box body 41 in a manner that it can rotate around a first axis extending left and right, and has a closed state in which the open opening is closed and an open state in which the open opening is opened. The first surface of the door body 42 faces backward in the closed state and faces upward in the open state. The mounting seat 1 of the detergent dispensing structure is disposed on the first surface of the door body 42, and when the door body 42 is closed or opened, the dispensing box 3 is in a state in which the open opening 300 faces upward under the action of its own gravity.

[0055] The above-mentioned spray arm 5 is a prior art and can be rotatably arranged in the box body 4. When the guide plate 2 is opened, water sprayed from the spray hole of the spray arm can enter the delivery box 3, dissolve the detergent in the delivery box 3, and then flow out from the leakage hole 310 and enter the box body 4.

[0056] The guide plate 2 of this embodiment can be opened before washing, or during washing by a controller or a driving mechanism. The driving mechanism can be an electric cylinder that can be telescopically moved, etc., to drive the guide plate 2 to move up and down.

[0057] When the guide plate 2 is open, since the opening 300 of the delivery box 3 of this embodiment faces upward and is partially located outside the opening 100 of the mounting base 1, when the installation height of the spray arm 5 changes, it can also be ensured that the water sprayed by the spray arm 5 can enter the delivery box 3.
