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 telescopically moved up and down being embedded in the support platform, and a driving mechanism capable of driving the sealing member to be telescopically moved up and down;

[0007] When closing the door, first flip the door body down to close the opening, then operate the drive mechanism to drive the seal to extend upward and tightly against the lower surface of the door body; when opening the door, the drive mechanism drives the seal 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, a driving mechanism drives the sealing member to move upward. The upward sealing force of the sealing member can be adjusted by controlling the driving force of the driving member, 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 sealing member is driven to move downward to release the seal between the sealing member and the door body, so that the door body can be flipped upward, which is easy to operate.

[0009] Preferably, the driving mechanism includes a first magnetic member and a second magnetic member, the sealing member is hollow inside to form a receiving cavity, the first magnetic member is arranged in the receiving cavity so as to be movable up and down, and the first magnetic member moves upward to drive the sealing member to extend upward, and moves downward to drive the sealing member to contract downward, and the second magnetic member is arranged in the door body and is arranged opposite to the first magnetic member. The above structure is adopted 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 second magnetic component is a superconducting component, including a conductive component in a closed loop structure. In the closed state, the conductive component includes a first conductive part arranged corresponding to the outer edge of the first magnetic component and a second conductive part arranged corresponding to the inner edge of the first magnetic component. In the conductive state, a magnetic field that can generate an attractive force on the first magnetic component is formed between the first conductive part and the second conductive part. With the above structure, in the closed and sealed state, the superconducting component is energized to generate a magnetic field that has an attractive force on the first magnetic component, thereby sucking and sealing the door body and the sealing component; when the door needs to be opened, the superconducting component is powered off, and the first magnetic component can drive the sealing component to shrink downward by falling due to its gravity, thereby canceling the seal with the lower surface of the door body, which is convenient and reliable to operate.

[0015] 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.

[0016] (1) When closing the door, first flip the door body down to close the opening, then operate the drive mechanism to drive the seal to extend upward and tightly contact the lower surface of the door body;

[0017] (2) When the door needs to be opened after washing is completed, the driving mechanism drives the seal to retract 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 after washing to be discharged;

[0018] (3) After exhausting, open the door upwards.

[0019] 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.

[0020] Compared with the prior art, the advantages of the present invention are: the present invention adopts a seal that can be extended and retracted up and down. When the door is closed, the driving mechanism drives the seal to move upward, and the upward sealing force of the seal can be adjusted by controlling the driving force of the driving member, so that the seal 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 seal is driven to move downward to release the seal between the seal and the door body, so that the door body can be flipped upward, which is easy to operate.

[0025] The present invention is further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 4 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 opening 11 at the top. The door body 2 is arranged at 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 opening 11 of the water tank body 1. A sealing member 3 that can be extended up and down is embedded in the support platform 12, and a driving mechanism 4 that can drive the sealing member 3 to extend up and down is also included.

[0027] 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 .

[0028] The door opening and closing method of the water tank type cleaning machine in this embodiment is:

[0029] When closing the door, first flip the door body 2 down to close the opening, then operate the driving mechanism to drive the sealing member 3 to extend upward and abut against the lower surface of the door body 2; when opening the door, the driving mechanism drives the sealing member 3 to contract downward and separate from the lower surface of the door body 2, and then flip the door body 2 upward.

[0030] The present invention adopts a sealing member 3 which can be extended and retracted up and down. When the door is closed, the driving mechanism drives the sealing member 3 to move upward. The upward sealing force of the sealing member 3 can be adjusted by controlling the driving force of the driving member, 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 sealing member 3 is driven to move downward to release the seal between the sealing member 3 and the door body 2, so that the door body 2 can be flipped upward, which is easy to operate.

[0031] The driving mechanism includes a first magnetic member 4 and a second magnetic member 5. The sealing member 3 is hollow inside to form a receiving chamber 30. The first magnetic member 4 is arranged in the receiving chamber 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. The second magnetic member 5 is arranged in the door body 2 and is arranged opposite to the first magnetic member 4. The above structure is adopted to facilitate driving the sealing member 3 to extend and retract up and down.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] The second magnetic member 5 is a superconducting element, including a conductive element in a closed loop structure. In the closed state, the conductive element includes a first conductive part 51 arranged corresponding to the outer edge of the first magnetic member 4 and a second conductive part 52 arranged corresponding to the inner edge of the first magnetic member 4. In the conductive state, a magnetic field that can generate an attractive force on the first magnetic member 4 is formed between the first conductive part 51 and the second conductive part 52. With the above structure, in the closed and sealed state, the superconducting element is energized to generate a magnetic field that has an attractive force on the first magnetic member 4, thereby tightly sucking and sealing the door body 2 and the sealing member 3; when the door needs to be opened, the superconducting element is powered off, and the first magnetic member 4 falls by its gravity to drive the sealing member 3 to shrink downward, thereby canceling the seal with the lower surface of the door body 2, which is convenient and reliable to operate.

[0037] 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:

[0038] (1) When closing the door, first turn the door body 2 downward to close the opening 11, and then operate the driving mechanism to drive the sealing member 3 to extend upward and abut against the lower surface of the door body 2;

[0039] (2) When the door needs to be opened after washing is completed, the driving mechanism drives the seal 3 to retract downward and separate from the lower surface of the door body 2, exposing a gap for the high-heat and humid air in the water tank body after washing to be discharged;

[0040] (3) After exhausting, open the door 2 upwards.

[0041] 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.
