DETAILED DESCRIPTION

[0029] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example

[0031] according to Figures 1 to 5 The under sink dishwasher shown includes:

[0032] The water tank body 1 has a first drain port 18 at the bottom thereof;

[0033] The dishwasher body is arranged below the sink body 1. The dishwasher body includes a machine wall 9 and a bowl basket 6 located in the machine wall 9. A cover plate 2 is arranged on the top of the bowl basket 6. The cover plate 2 has a first sealing portion 15 and a second sealing portion 12. The first sealing portion 15 can seal or open a first drain port 18, and the second sealing portion 12 can be pressed against or separated from the machine wall 9. A second drain port 19 is arranged at the bottom of the sink body 1 near the cover plate 2.

[0034] The cover plate 2 has a lower position, a middle position and an upper position during opening. When in the lower position, the first sealing portion 15 and the second sealing portion 12 are both sealed accordingly; when in the middle position, the first sealing portion 15 opens the first drain port 18, and the second sealing portion 12 is sealed; when in the upper position, the first sealing portion 15 and the second sealing portion 12 are both opened accordingly.

[0035] Under normal circumstances, the accumulated water in the sink body 1 needs to be discharged from the second drain port 19. When the accumulated water is emptied, the cover plate 2 is opened. When the second drain port 19 is blocked and the accumulated water in the sink body 1 cannot be discharged, or when the cover plate 2 is accidentally opened when there is accumulated water in the sink body 1, it is necessary to drain the water through the first drain port 18. During the opening process of the cover plate 2, when it rises to the middle position in the first rising stage, the first sealing part 15 fails, the first drainage channel 7 is connected with the sink body 1, and the accumulated water in the sink body 1 is discharged from the first drainage channel 7. At this time, the second sealing part 12 maintains the seal between the cover plate 2 and the machine wall 9 to keep the bowl basket 6 and the sink body 1 isolated, so as to prevent the accumulated water from entering the dishwasher. When the cover plate 2 continues to rise and rises to the upper position in the second rising stage, the cover plate 2 and the machine wall 9 are completely separated, and the second sealing part 12 generated by the end surface bonding between the two fails. At this time, the cover plate 2 can be opened normally. This can effectively prevent the accumulated water from flowing directly into the dishwasher when there is accumulated water in the sink body 1 and the cover 2 is accidentally opened.

[0036] In an optional embodiment, the bowl basket 6 can be raised and lowered in the machine wall 9.

[0037] In order to save space for arranging the dishwasher, the dishwasher is integrated under the sink, so the height of the dishwasher is reduced. To avoid inconvenience in operation, the present solution sets a lifting device under the bowl basket 6, and uses the lifting device to lift the bowl basket 6 to a certain height, so that the operator can take and put the dishes. Since the dishwasher is located under the sink, the bowl basket 6 needs to pass through the bottom end surface of the sink body 1 during the lifting process. In order to prevent the accumulated water in the sink body 1 from flowing into the dishwasher during the lifting process of the bowl basket 6, the present solution uses the cooperation between the cover plate 2, the window structure 16 and the machine wall 9 to achieve a sealing effect and discharge the accumulated water in the sink body 1 when the bowl basket 6 rises, so that when the cover plate 2 is opened, the accumulated water in the sink body 1 will not flow into the dishwasher, but will flow into the first drainage channel 7 around the bowl basket 6.

[0038] The lifting device drives the bowl basket 6 to rise in a two-stage process. The middle state is used to release the first sealing portion 15 between the cover plate 2 and the window structure 16, so that the residual water in the sink body 1 is discharged from the first drainage channel 7. The upper state is used to release the second sealing portion 12 between the cover plate 2 and the machine wall 9, so that the cover plate 2 can be opened relative to the bowl basket 6 for taking and placing dishes.

[0039] Compared with the conventional design of placing the dishwasher under the sink, the present invention can prevent the accumulated water from flowing into the dishwasher when there is accumulated water in the sink body 1 and the lifting device is accidentally started or the cover 2 is accidentally opened.

[0040] In an optional embodiment, the sink dishwasher further includes a second drainage channel 3 for draining water from the sink body 1, and the second drainage channel 3 is located at the bottom end surface of the sink body 1. The second drainage channel 3 enables the sink body 1 to store and drain water normally, thereby having the basic function of a sink. The second drainage channel 3 and the first drainage channel 7 work independently, and each has an independent diversion pipe connected to the main drainage system.

[0041] In an optional embodiment, the outer edge of the first sealing portion 15 can be tightly pressed against the edge of the first drain port 18 at the bottom of the sink body 1 .

[0042] The bottom of the sink body 1 is provided with a stepped groove 14, and the bottom of the stepped groove 14 is provided with a receiving cavity for installing the dishwasher body, the machine wall 9 is embedded in the receiving cavity, and the first drain port 18 is provided in the side surrounding area of ​​the receiving cavity;

[0043] The first sealing portion 15 can be tightly pressed against the groove wall of the stepped groove 14 .

[0044] The cover plate 2 and the machine wall 9 are in contact with each other or not; when the bowl basket 6 is in the middle position rising state in the two-stage rising, the cover plate 2 and the machine wall 9 are in contact with each other to form a second sealing portion 12, the contact surface is parallel to the rising direction of the bowl basket 6, and the second drainage channel 3 is connected to the sink body 1; when the bowl basket 6 is in the upper position rising state in the two-stage rising, the cover plate 2 and the machine wall 9 are not in contact with each other.

[0045] The cover plate 2 and the machine wall 9 form a second sealing portion 12 through the fitting of the end faces. When the cover plate 2 rises with the bowl basket 6, in the first rising stage, the first sealing portion 15 fails, the first drainage channel 7 is connected with the water tank body 1, and the accumulated water in the water tank body 1 is discharged from the first drainage channel 7. At this time, the function of the second sealing portion 12 is to maintain the seal between the cover plate 2 and the machine wall 9 to keep the bowl basket 6 and the water tank body 1 isolated to prevent the accumulated water from entering the dishwasher. When the cover plate 2 continues to rise with the bowl basket 6 and reaches the second rising stage, the cover plate 2 and the machine wall 9 are completely separated, and the second sealing portion 12 formed by the end face fitting between the two fails. At this time, the cover plate 2 can be opened normally.

[0046] The fitting surface is parallel to the rising direction of the bowl basket 6, which ensures that the cover plate 2 and the machine wall 9 are tightly fitted during the rising process of the bowl basket 6, thereby avoiding failure of the second sealing portion 12. At the same time, the constraint of the machine wall 9 on the cover plate 2 prevents the cover plate 2 from shifting sideways, thereby affecting the sealing between the cover plate 2 and the machine wall 9.

[0047] In an optional embodiment, the edges of the cover plate 2 and the window structure 16 are fitted or not fitted to each other;

[0048] When the dishwasher is in operation, the cover plate 2 and the edge of the window structure 16 fit together to form a first sealing portion 15, and the second drainage channel 3 is sealed with the sink body 1;

[0049] When the bowl basket 6 is in the raised state, the cover plate 2 is not in contact with the edge of the window structure 16 .

[0050] The cover plate 2 firstly serves as the bottom end surface of the sink body 1, and is used to ensure the structural integrity of the sink body 1. Another function of the cover plate 2 is to serve as a part of the sealing structure of the dishwasher. Through the cooperation between the cover plate 2, the window structure 16, and the machine wall 9, the sealing of the dishwasher during operation and the drainage of accumulated water when the bowl basket 6 rises in the middle position are achieved.

[0051] The airtightness during the operation of the dishwasher is achieved by the cooperation between the cover plate 2 and the edge of the window structure 16, and the first sealing part 15 is achieved by the fit between the edge of the cover plate 2 and the edge of the window structure 16. When the bowl basket 6 is in the first ascending stage, the cover plate 2 and the window structure 16 are separated, and the first sealing part 15 fails. At this time, the accumulated water in the water tank body 1 can flow into the first drainage channel 7 from the gap between the cover plate 2 and the window structure 16.

[0052] In an optional embodiment, the bottom end surface of the stepped groove 14 is inclined downward in a direction away from the machine wall 9 .

[0053] The bottom end surface of the water tank body 1 is located at the window structure 16 and forms a step groove 14 downward. The edge of the window structure 16 is the vertical surface of the step groove 14, and the first drainage channel 7 is located at the bottom of the step groove 14. The width D of the bottom end surface of the step groove 14 is ≥ 65 mm, and the angle a between the bottom end surface of the step groove 14 and the horizontal plane is between 1° and 3°, so that the step groove 14 is easy to clean. When there is water accumulation in the step groove 14, the accumulated water flows along the inclined direction of the bottom end surface of the step groove 14 to away from the machine wall 9.

[0054] In an optional embodiment, the sink dishwasher also includes a lifting device, which includes a threaded screw motor 5, which is engaged with the bowl basket 6. An end of the machine wall 9 close to the bowl basket 6 is provided with a roller 11 for circumferentially limiting the bowl basket 6, and a positioning plate 10 for cooperating with the roller 11 is provided at a corresponding position of the bowl basket 6.

[0055] The threaded screw motor 5 in the lifting device is fixedly arranged in the accommodating cavity and does not rise or fall with the bowl basket 6. The mechanism corresponding to the threaded screw motor 5 on the bowl basket 6 is a threaded hole located in the middle of the bowl basket 6. The threaded screw motor 5 realizes the lifting and lowering drive of the bowl basket 6 through the meshing between the screw and the threaded hole. The bowl basket 6 is in a state of receiving the drive of the threaded screw motor 5 during the lifting process, and does not have the lifting power itself, which simplifies the structure and weight of the bowl basket 6 and avoids the introduction of additional weight when the threaded screw motor 5 is arranged on the bowl basket 6. At the same time, since the screw and the threaded hole have a self-locking effect when meshing, the lifting and lowering of the bowl basket 6 can only be achieved by the motor driving the screw to rotate. When the motor stops rotating, the bowl basket 6 is affected by the threaded teeth on the screw to maintain the current lifting height. At this time, when the bowl basket is pressed down by an external force, it will not cause the screw to rotate in the opposite direction, thereby avoiding the motor being damaged by the rotation of the external force.

[0056] The movement of the bowl basket 6 is not restricted, and the movement of the bowl basket 6 can be realized by the combination of the threaded screw motor 5+roller 11 or by the electric push rod+slide rail.

[0057] In an optional embodiment, there is an angle between the bottom end surface of the water tank body 1 and the horizontal plane, and the second drain port 19 is located at the lowest point of the bottom end surface of the water tank body 1 .

[0058] The bottom end surface of the water tank body 1 forms an angle a with the horizontal plane, and the angle a is between 1° and 3°, so as to ensure that no water will remain in the water tank body 1 as much as possible.

[0059] In an optional embodiment, the upper end surface of the cover plate 2 is parallel to the bottom end surface of the water tank body 1. The cover plate 2 is parallel to the bottom end surface of the water tank body 1 to ensure the flatness of the bottom end surface of the water tank body 1.

[0060] In an optional embodiment, the sink dishwasher further includes a garbage disposal machine 4, and the first drain port 18 is connected to the garbage disposal machine 4 through a first drain channel 7. The sink dishwasher further includes a second drain port 19 for draining water from the sink body 1, the second drain port 19 is located at the bottom end surface of the sink body 1, and the second drain port 19 is connected to the garbage disposal machine 4 through a second drain channel 3.

[0061] In an optional embodiment, the sink dishwasher includes a secondary water tank 20 arranged in parallel with the sink body 1, and the secondary water tank 20 is connected to the garbage disposal machine 4. In this way, the garbage disposal machine 4 is connected to both the drain port on the sink body 1 and the drain port of the secondary water tank 20. The garbage in the sink body 1 and the secondary water tank 20 can be processed by one garbage disposal machine 4 at the same time, which is convenient for centralized processing of garbage.

[0062] In an optional embodiment, the cover plate 2 and the bowl basket 6 can be connected or snapped together so that the cover plate 2 can be opened or closed relative to the bowl basket 6. A first fixing bracket 17 and a second fixing bracket 8 are provided on a side of the cover plate 2 close to the bowl basket 6, and a positioning column 13 for supporting the first fixing bracket 17 and the second fixing bracket 8 is provided at a corresponding position of the bowl basket 6, and the first fixing bracket 17 is rotatably connected to the corresponding positioning column 13.

[0063] The first fixing bracket 17 and the second fixing bracket 8 are used to keep a certain distance between the cover plate 2 and the bowl basket 6, so as to ensure the normal cooperation between the bowl basket 6 and other structures in the dishwasher, such as the spray arm, and the cooperation between the cover plate 2 and the window structure 16, so that the bottom end surface of the sink body 1 is relatively flat. The first fixing bracket 17 is rotatably connected to the positioning column 13 at the corresponding position of the bowl basket 6. Since the rotatable connection is located between the cover plate 2 and the bowl basket 6, the rotatable connection structure is prevented from being contaminated by oil stains in the sink body 1, thereby increasing the reliability of the rotatable connection.

[0064] The cover plate 2 can also be opened to the pre-open state by using the press-and-pop method of the water-leakage cover of the wash basin, and the surface of the cover plate 2 is pressed to achieve a short-distance displacement up and down to drain away excess water stains.

[0065] In an optional embodiment, a seal is provided at the first sealing portion 15 and / or the second sealing portion 12. That is, a seal is provided at the first sealing portion 15, or a seal is provided at the second sealing portion 12, or a seal is provided at the first sealing portion 15 and the second sealing portion 12, respectively, so that the sealing performance at the first sealing portion 15 and the second sealing portion 12 can be further improved.

[0066] When the dishwasher finishes running, the accumulated water in the sink body 1 is first discharged through the second drainage channel 3, and the threaded screw motor 5 is operated to lift the bowl basket 6. In the first rising stage, the cover plate 2 is separated from the edge of the window structure 16, and the first sealing portion 15 fails. The accumulated water that may remain in the sink body 1 is discharged from the first drainage channel 7. The residue around the cover plate 2 drips downward to the step surface of the sink through gravity, and then enters the first drainage channel 7, ensuring that stains cannot remain on the edge of the cover plate 2. At this time, the second sealing portion 12 is in a sealed state to prevent accumulated water from flowing into the dishwasher. The bowl basket 6 continues to rise, and the second sealing portion 12 is in a continuously sealed state. When the bowl basket 6 is in the second rising stage, the cover plate 2 is separated from the machine wall 9, the second sealing portion 12 fails, and at the same time, the rotation constraint of the machine wall 9 on the cover plate 2 fails. When the bowl basket 6 rises to the highest point, the threaded screw motor 5 maintains the state of the bowl basket 6. At this time, the operator can manually open the cover plate 2 to take out or put in dishes. When the cover plate 2 is in the open state, the accumulated water on the cover plate 2 can fall from the lowest point of the cover plate 2 into the stepped groove 14, and then fall into the first drainage channel 7.
