Description

Technical Field

[0001] The invention relates to the technical field of dishwashers, in particular to a door opening and closing method of a sink-type washing machine. Background Art

[0002] As people's living standards continue to improve, dishwashers, as a kitchen appliance, are increasingly entering households. Sink-type washing machines usually adopt a door body flip-up opening structure. For example, the Chinese patent "A Dishwasher" (application number: CN202222917579.0) with authorization announcement number CN219846429U discloses a structure including an inner tank and a door body, wherein the inner tank has a washing chamber with an open top, and the edge of the opening extends laterally outward to form an annular flange; the door body can be rotatably arranged at the opening of the inner tank, and can open or close the opening, and when the door body is in the closed state, a seal is provided between the lower surface of the door body and the opening to seal the two.

[0003] Although the above-mentioned seal can achieve sealing of the door body and the opening on the top of the inner tank, the seal is usually a plastic part. There is a hot water cleaning process in the washing program. After long-term use, the seal may be partially deformed, resulting in poor elasticity and poor sealing effect, affecting the sealing effect, causing overflow of high-temperature steam or hot water, or external accumulated water invading the washing chamber when the sink is used, affecting the washing chamber environment and cleaning effect. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a method for opening and closing the door of a sink type cleaning machine, which can self-adjust the sealing force to improve the sealing effect, avoid overflow of washing steam or hot water, and avoid intrusion of external water stains, in view of the current status of the prior art.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] A method for opening and closing the door of a water tank type cleaning machine, the cleaning machine comprising a water tank body and a door body, the water tank body having an opening at the top, the door body being arranged at the top of the water tank body and being used to open or close the door body, a horizontally extending support platform being arranged at the edge of the opening of the water tank body, a sealing member capable of being extended and retracted up and down being embedded in the support platform, a first magnetic member capable of driving the top of the sealing member to move up and down being arranged in the seal, a second rotatable magnetic member being arranged at the bottom of the support platform, the second magnetic member being attracted or repelled by the first magnetic member as the second magnetic member rotates;

[0007] When closing the door, first flip the door body down to close the opening, then rotate the second magnetic part to repel the first magnetic part, drive the first magnetic part to drive the sealing part to extend upward and tightly against the lower surface of the door body; when opening the door, rotate the second magnetic part to attract the first magnetic part, drive the first magnetic part to drive the sealing part to shrink downward and separate from the lower surface of the door body, and then flip the door body upward.

[0008] The present invention adopts a sealing member that can be extended and retracted up and down. When the door is closed, the second magnetic member drives the first magnetic member to drive the sealing member to move upward. The upward sealing force of the sealing member can be adjusted by controlling the relative distance between the magnetic members, so that the sealing member can always be reliably sealed with the lower surface of the door body to avoid overflow of washing steam or hot water and invasion of external water stains. When opening and closing, the second magnetic member drives the first magnetic member to drive the sealing member to retract downward, thereby releasing the seal between the sealing member and the door body, and the door body can be flipped upward, which is easy to operate.

[0009] Preferably, the sealing member is hollow inside to form a receiving cavity, and the first magnetic member is disposed in the receiving cavity so as to be movable up and down. The above structure is used to facilitate driving the sealing member to extend and retract up and down.

[0010] Preferably, the sealing member comprises a sealing pad at the bottom and an outer wall, an inner wall and a top wall extending upward from the top edge of the sealing pad, the outer wall and the inner wall forming a corrugated folding structure corresponding to each other, and the first magnetic member is arranged on the lower surface of the top wall. As a result, the sealing member can be stably extended and retracted during the extension and retraction process, avoiding local deformation, thereby maintaining good sealing performance and service life.

[0011] Preferably, sealing ribs are protruded from both sides of the sealing gasket, and the sealing ribs are elastically squeezed and sealed with the corresponding inner side surface of the accommodating cavity. This structure facilitates the sealing gasket to be tightly constrained in the accommodating cavity and improves the sealing performance of the accommodating cavity.

[0012] Preferably, the top wall includes a first part located in the central part and arranged horizontally, a second part connected to the outside of the first part, and a third part connected to the inside of the first part. When the seal is in the extended state, the first part abuts against the lower surface of the door body, the second part is arranged to be gradually tilted downward from the inside to the outside, and the third part is gradually tilted downward from the outside to the inside. When the seal is in the contracted state, the first part, the second part, and the third part are spliced ​​together to form a cover that can horizontally cover the top opening of the accommodating groove to seal the accommodating groove. With the above structure, in the closed and sealed state, the second part can prevent the invasion of external water stains, and the third part is conducive to guiding the water stains downward in time to avoid water stains overflowing; in the open state, the cover seals the top opening of the accommodating cavity to prevent external water from entering the accommodating cavity.

[0013] Preferably, the inner side of the water tank body is provided with a drainage hole for draining the accumulated water in the accommodating tank into the water tank body. This structure can drain the water stains in the accommodating tank into the water tank in time, avoiding the long-term accumulation of water stains in the accommodating cavity and the growth of mold and bacteria.

[0014] Preferably, the first magnetic member is an annular structure arranged around the top open periphery of the water tank body, the second magnetic member includes multiple sections arranged corresponding to the left side, front side, right side, and rear side of the water tank body, the ends of two adjacent sections are connected by a flexible tube at the bend of the water tank body, and the sections of the second magnetic member rotate synchronously. The above structure facilitates the rotation of the second magnetic member and eliminates the interference problem at the corner.

[0015] Preferably, the second magnetic member is embedded in a cylindrical shaft and penetrates the radial direction of the cylindrical shaft, and a limiting hook capable of rotating the cylindrical shaft on the water tank body is provided at the bottom of the support platform. This structure facilitates limiting the second magnetic member outside the water tank body.

[0016] Preferably, the cross section of the limit hook is a C-shaped structure, and the C-shaped structure and the outer side surface of the water tank body together enclose a limit cavity that can rotate with the cylindrical shaft. This structure can make the second magnetic member rotate stably and reliably.

[0017] Preferably, the outer surface of the cylindrical shaft exposed from the limit hook is provided with a gear ring, and a motor is provided outside the limit hook, and a gear that can mesh with the gear ring is connected to the output shaft of the motor. This structure facilitates driving the second magnetic member to rotate.

[0018] As an improvement, when the door is closed, a gap is formed between the lower surface of the door body and the support table for the discharge of hot and humid steam after washing, and the height of the gap is lower than the height of the seal extending upward.

[0019] (1) When closing the door, first flip the door down to close the opening, drive the seal to extend upward and tightly contact the lower surface of the door;

[0020] (2) When the door needs to be opened after washing is completed, the seal is driven to shrink downward and separate from the lower surface of the door body, exposing a gap for the high-heat and humid air in the water tank body to be discharged after washing;

[0021] (3) After exhausting, open the door upwards.

[0022] The above-mentioned door opening process can avoid burns to users caused by high-temperature and humid air after hot water washing, thereby providing safety and user experience.

[0023] Compared with the prior art, the advantages of the present invention are: the present invention adopts a sealing member that can be extended and retracted up and down. When the door is closed, the second magnetic member drives the first magnetic member to drive the sealing member to move upward. The upward sealing force of the sealing member can be adjusted by controlling the relative distance between the magnetic members, so that the sealing member can always be reliably sealed with the lower surface of the door body, avoiding the overflow of washing steam or hot water and the invasion of external water stains; when opening and closing, the second magnetic member drives the first magnetic member to drive the sealing member to retract downward, releasing the seal between the sealing member and the door body, and the door body can be flipped upward, which is easy to operate.

[0029] The present invention is further described in detail below with reference to the accompanying drawings.

[0030] like Figures 1 to 5 As shown, the cleaning machine of this embodiment includes a water tank body 1 and a door body 2. The water tank body 1 has an open top, and the door body 2 is arranged on the top of the water tank body 1 and is used to open or close the door body 2. A horizontally extending support platform 12 is arranged at the edge of the water tank body 1, and a sealing member 3 that can be extended and retracted up and down is embedded in the support platform 12. A first magnetic member 4 that can drive the top of the sealing member 3 to move up and down is arranged in the sealing member 3. A rotatable second magnetic member 5 is arranged at the bottom of the support platform 12, and the second magnetic member 5 attracts or repels the first magnetic member 4 as it rotates.

[0031] The support platform 12 is provided with a receiving groove 121 with a top opening, and the lower part of the sealing member 3 is embedded in the receiving groove 121 .

[0032] When closing the door, first flip the door body 2 down until it is almost closed, then rotate the second magnetic part 5 to repel the first magnetic part 4, drive the first magnetic part 4 to drive the sealing part 3 to extend upward and tightly against the lower surface of the door body 2; when opening the door, rotate the second magnetic part 5 to attract the first magnetic part 4, drive the first magnetic part 4 to drive the sealing part 3 to shrink downward and separate from the lower surface of the door body 2, and flip the door 2 upward to open it.

[0033] The present embodiment adopts a sealing member 3 which can be extended and retracted up and down. When the door is closed, the second magnetic member 5 drives the first magnetic member 4 to drive the sealing member 3 to move upward. The upward sealing force of the sealing member 3 can be adjusted by controlling the relative distance between the magnetic members, so that the sealing member 3 can always be reliably sealed with the lower surface of the door body 2 to avoid overflow of washing steam or hot water and invasion of external water stains. When opening and closing, the second magnetic member 5 drives the first magnetic member 4 to drive the sealing member 3 to retract downward, thereby releasing the seal between the sealing member 3 and the door body 2, and the door body 2 can be flipped upward, which is easy to operate.

[0034] The sealing member 3 is hollow inside to form a receiving cavity 30 , and the first magnetic member 4 is disposed in the receiving cavity 30 so as to be movable up and down. The first magnetic member 4 moves upward to drive the sealing member 3 to extend upward, and moves downward to drive the sealing member 3 to contract downward.

[0035] The sealing member 3 includes a sealing pad 31 at the bottom, and an outer wall 311, an inner wall 312 and a top wall 313 extending upward from the top edge of the sealing pad 31. The outer wall 311 and the inner wall 312 form a corrugated folding structure corresponding to each other, and the first magnetic member 4 is arranged on the lower surface of the top wall 313. As a result, the sealing member 33 can be stably extended and retracted during the extension and retraction process, avoiding local deformation, thereby maintaining good sealing performance and service life.

[0036] Sealing ribs 310 are respectively provided on both sides of the sealing gasket 31, and the sealing ribs 310 are elastically squeezed and sealed with the corresponding inner side surfaces of the receiving groove 121. This structure facilitates the sealing gasket 31 to be tightly constrained in the receiving groove 121 and improves the sealing performance of the receiving groove 121.

[0037] The top wall 313 includes a first portion 3131 located in the central part and arranged horizontally, a second portion 3132 connected to the outside of the first portion 3131, and a third portion 3133 connected to the inside of the first portion 3131. When the seal 3 is in the extended state, the first portion abuts against the lower surface of the door body 2, the second portion 3132 is arranged to be gradually tilted downward from the inside to the outside, and the third portion 3133 is gradually tilted downward from the outside to the inside; when the seal 3 is in the contracted state, the first portion 3131, the second portion 3132, and the third portion 3133 are spliced ​​together to form a cover that can horizontally cover the top opening of the receiving groove 121 to seal the receiving groove 121. With the above structure, in the closed door sealing state, the second portion 3132 can prevent the invasion of external water stains, and the third portion 3133 is conducive to timely guiding the water stains downward to prevent the water stains from overflowing; in the open door state, the cover seals the top opening of the receiving groove 121 to prevent external water from entering the receiving groove 121.

[0038] The inner side of the water tank body 1 is provided with a drainage hole 13 for draining the accumulated water in the receiving groove 121 into the water tank body 1. This structure can drain the water stains in the receiving groove 121 into the water tank in time, avoiding the long-term accumulation of water stains in the receiving groove 121 and mold and bacteria breeding.

[0039] In this embodiment, the first magnetic member 4 and the second magnetic member 5 are both magnets. The first magnetic member 4 is an annular structure arranged around the top open periphery of the water tank body 1, and the second magnetic member 5 includes multiple sections arranged corresponding to the left side, front side, right side, and rear side of the water tank body 1. The ends of two adjacent sections are connected by a flexible tube 51 at the bend of the water tank body 1, and the sections of the second magnetic member 5 rotate synchronously. The above structure facilitates the rotation of the second magnetic member 5 and eliminates the interference problem at the corner.

[0040] The second magnetic member 5 is embedded in a cylindrical shaft 52 and penetrates the radial direction of the cylindrical shaft 52. A limiting hook 53 is provided at the bottom of the support platform 12 to constrain the cylindrical shaft 52 to rotate on the water tank body 1. This structure facilitates limiting the second magnetic member 5 outside the water tank body 1.

[0041] The cross section of the limit hook 53 is a C-shaped structure, and the C-shaped structure and the outer side of the water tank body 1 together enclose a limit cavity that can rotate with the cylindrical shaft 52. This structure can make the second magnetic member 5 rotate stably and reliably. The outer surface of the cylindrical shaft 52 exposed from the limit hook 53 is provided with a gear ring 521, and the outer side of the limit hook 53 is provided with a motor 54, and the output shaft of the motor 54 is connected to a gear 55 that can mesh with the gear ring 521 for transmission. This structure facilitates the rotation of the second magnetic member 5.

[0042] In this embodiment, when the door is closed, a gap 20 is formed between the lower surface of the door body 2 and the tray for the exhaust of hot and humid steam after washing. The height of the gap 20 is lower than the height of the seal 3 extending upward. The method of opening and closing the door of the water tank type washing machine is:

[0043] (1) When closing the door, first flip the door body 2 downward until it is almost closed, then rotate the second magnetic member 5 to repel the first magnetic member 4, drive the first magnetic member 4 to drive the sealing member 3 to extend upward and tightly abut against the lower surface of the door body 2;

[0044] (2) When the door needs to be opened after washing, the second magnetic member 5 is rotated to attract the first magnetic member 4, driving the first magnetic member 4 to drive the sealing member 3 to shrink downward and separate from the lower surface of the door body 2, exposing the gap 20 for the high-heat and humid air in the water tank body 1 after washing to be discharged;

[0045] (3) After exhausting, open the door 2 upwards.

[0046] The above-mentioned door opening process can avoid burns to users caused by high-temperature and humid air after hot water washing, thereby providing safety and user experience.
