Description

Technical Field

[0001] This invention relates to the field of dishwasher technology, specifically to a sink-type washing machine. Background Technology

[0002] With the continuous improvement of people's living standards, dishwashers, as a type of kitchen appliance, are increasingly entering households. Sink-type dishwashers typically employ a top-opening door structure. For example, Chinese patent CN219846429U, entitled "A Dishwasher" (application number: CN202222917579.0), discloses a structure including an inner tub and a door. The inner tub has a washing chamber with an open top, and the edge of the open edge extends laterally outward to form an annular flange. The door is rotatably disposed at the open end of the inner tub and can be opened or closed. When the door is closed, a sealing element is provided between the lower surface of the door and the open end to seal them together.

[0003] Although the above-mentioned seals can seal the door and the top opening of the inner tank, the seals are usually made of plastic. During the washing process, there is a hot water cleaning process. After long-term use, the seals may deform and lose elasticity, resulting in a poorer sealing effect. This can lead to the overflow of high-temperature steam or hot water, or external water entering the washing chamber during the use of the sink, affecting the washing chamber environment and the cleaning effect. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a water tank type cleaning machine that can self-adjust sealing force to improve sealing effect, prevent washing steam or hot water from overflowing, and prevent external water stains from entering, in light of the current state of the prior art.

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

[0006] A water tank type cleaning machine includes a water tank body and a door. The top of the water tank body has an opening. The door is located on the top of the water tank body and is used to open or close the door. A horizontally extending support is provided at the edge of the opening of the water tank body. A sealing element that can extend and retract vertically is embedded in the support. The machine also includes a drive mechanism that can drive the sealing element to extend and retract vertically. When the door is closed, the sealing element extends upward and its top is pressed tightly against the lower surface of the door body to seal.

[0007] This invention uses a retractable seal. When the door is closed, the drive mechanism drives the seal to move upward. The upward sealing force of the seal can be adjusted by controlling the driving force of the drive mechanism, so that the seal can always reliably seal with the lower surface of the door, preventing washing steam or hot water from overflowing and preventing external water stains from entering. When opening or closing, the drive mechanism moves the seal downward, releasing the seal between the seal and the door, so that the door can be opened upward, which is convenient to operate.

[0008] Preferably, the driving mechanism includes a first magnetic element and a second magnetic element. The sealing element has a hollow interior forming a receiving cavity. The first magnetic element is movably disposed within the receiving cavity, and its upward movement causes the sealing element to extend upward, while its downward movement causes the sealing element to retract downward. This structure facilitates the vertical extension and retraction of the sealing element.

[0009] In one preferred embodiment, the second magnetic component is disposed within the door body and arranged opposite to the first magnetic component. In a conductive state, a magnetic field capable of attracting the first magnetic component is formed between the first conductive portion and the second conductive portion. In another preferred embodiment, the second magnetic component is disposed below the support platform and arranged opposite to the first magnetic component. In a conductive state, a magnetic field capable of repelling the first magnetic component is formed between the first conductive portion and the second conductive portion.

[0010] Preferably, the sealing element includes a sealing gasket at the bottom and an outer sidewall, an inner sidewall, and a top wall extending upward from the top edge of the sealing gasket. The outer sidewall and the inner sidewall form a corresponding corrugated folded structure, and the first magnetic element is disposed on the lower surface of the top wall. This design allows the sealing element to expand and contract stably during expansion and contraction, avoiding localized deformation and thus maintaining good sealing performance and service life.

[0011] Preferably, the sealing gasket has protruding sealing ribs on both sides, which elastically compress and seal against the corresponding inner surface of the accommodating cavity. This structure facilitates the tight confinement of the sealing gasket within the accommodating cavity and improves the sealing performance of the cavity.

[0012] Preferably, the top wall includes a first part located in the center 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 extended, the first part abuts against the lower surface of the door, the second part gradually slopes downwards from the inside out, and the third part gradually slopes downwards from the outside in. When the seal is retracted, the first part, the second part, and the third part are joined together to form a cover that horizontally covers the top opening of the receiving groove, thereby sealing the receiving groove. With this structure, in the closed and sealed state, the second part prevents external water intrusion, and the third part helps to guide water downwards in a timely manner to prevent water overflow. In the open state, the cover seals the top opening of the receiving cavity, preventing external water from entering the receiving cavity.

[0013] Preferably, the inner side of the water tank body is provided with a drain hole for draining water accumulated in the receiving tank into the water tank body. This structure can promptly drain water stains from the receiving tank into the water tank, preventing water stains from accumulating in the receiving cavity for a long time and causing mold and bacteria growth.

[0014] Preferably, the second magnetic component is a superconducting element, including a conductive component with a closed-loop structure. In the closed state, the conductive component includes a first conductive portion arranged corresponding to the outer edge of the first magnetic component and a second conductive portion arranged corresponding to the inner edge of the first magnetic component. In the conductive state, a magnetic field is formed between the first conductive portion and the second conductive portion that can attract the first magnetic component. With the above structure, in the closed and sealed state, energizing the superconducting element generates a magnetic field that attracts the first magnetic component, thereby tightly sealing the door and the sealing component. When it is necessary to open the door, de-energizing the superconducting element allows the first magnetic component to fall under its own weight, causing the sealing component to retract downwards, thereby canceling the seal with the lower surface of the door. This operation is convenient and reliable.

[0015] As an improvement, when the door is closed, a gap is formed between the lower surface of the door and the support table to allow hot, humid steam to escape after washing. The height of this gap is lower than the height of the upward extension of the seal. This structure prevents hot, humid steam from hitting the user's face after hot water washing, thus improving safety and user experience.

[0016] Compared with the prior art, the advantages of the present invention are as follows: The present invention uses a sealing element that can extend and retract vertically. In the closed state, the drive mechanism drives the sealing element to move upward. The upward sealing force of the sealing element can be adjusted by controlling the driving force of the drive element, so that the sealing element can always reliably seal with the lower surface of the door, preventing washing steam or hot water from overflowing and preventing external water stains from entering. When opening and closing, the drive sealing element moves downward to release the seal between the sealing element and the door, so that the door can be opened upward, which is convenient to operate.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] Example 1:

[0024] like Figures 1-4 As shown, the cleaning machine of this embodiment includes a water tank body 1 and a door body 2. The top of the water tank body 1 has an opening 11, and the door body 2 is located on the top of the water tank body 1 and is used to open or close the door body 2. A horizontally extending support 12 is provided at the edge of the opening 11 of the water tank body 1. A sealing member 3 that can extend and retract vertically is embedded in the support 12. The machine also includes a drive mechanism 4 that can drive the sealing member 3 to extend and retract vertically. In the closed state, the sealing member 3 extends upward and its top is pressed tightly against the lower surface of the door body 2 to seal.

[0025] The support 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. In the closed state, the sealing member 3 extends upward and the top is pressed tightly against the lower surface of the door body 2 to seal.

[0026] The driving mechanism includes a first magnetic element 4 and a second magnetic element 5. The sealing element 3 has a hollow interior forming a receiving cavity 30. The first magnetic element 4 is movably disposed within the receiving cavity 30. Moving the first magnetic element 4 upward causes the sealing element 3 to extend upward, and moving it downward causes the sealing element 3 to retract downward. The second magnetic element 5 is disposed within the door body 2 and is arranged opposite to the first magnetic element 4. This structure facilitates the vertical extension and retraction of the sealing element 3.

[0027] The sealing element 3 includes a sealing gasket 31 at the bottom and an outer sidewall 311, an inner sidewall 312, and a top wall 313 extending upward from the top edge of the sealing gasket 31. The outer sidewall 311 and the inner sidewall 312 form a corresponding corrugated folded structure. A first magnetic element 4 is disposed on the lower surface of the top wall 313. The above results allow the sealing element 33 to expand and contract stably during the expansion and contraction process, avoiding local deformation, thereby maintaining good sealing performance and service life.

[0028] Sealing ribs 310 are protruding on both sides of the sealing gasket 31, and the sealing ribs 310 elastically compress and seal against the corresponding inner surface of the receiving groove 121. This structure facilitates the tight confinement of the sealing gasket 31 in the receiving groove 121 and improves the sealing performance of the receiving groove 121.

[0029] The top wall 313 includes a first part 3131 located in the center and arranged horizontally, a second part 3132 connected to the outside of the first part 3131, and a third part 3133 connected to the inside of the first part 3131. When the seal 3 is in the extended state, the first part abuts against the lower surface of the door body 2, the second part 3132 is arranged gradually downward from the inside to the outside, and the third part 3133 is arranged gradually downward from the outside to the inside. When the seal 3 is in the contracted state, the first part 3131, the second part 3132, and the third part 3133 are joined together to form a cover that can horizontally cover the top opening of the receiving groove 121, thereby sealing the receiving groove 121. With the above structure, in the closed and sealed state, the second part 3132 can prevent external water stains from entering, and the third part 3133 helps to guide water stains downward in time to prevent water stains from overflowing. In the open state, the cover seals the top opening of the receiving cavity 30, preventing external water from entering the receiving cavity 30.

[0030] The inner side of the water tank body 1 is provided with a drain hole 13 for draining water in the receiving tank 121 to the water tank body 1. This structure can drain water stains in the receiving tank 30 into the water tank in a timely manner, avoiding water stains from accumulating in the receiving cavity 30 for a long time and causing mold and bacteria growth.

[0031] The second magnetic component 5 is a superconducting element, including a conductive component with a closed-loop structure. In the closed state, the conductive component includes a first conductive portion 51 arranged corresponding to the outer edge of the first magnetic component 4 and a second conductive portion 52 arranged corresponding to the inner edge of the first magnetic component 4. In the conductive state, a magnetic field that can attract the first magnetic component 4 is formed between the first conductive portion 51 and the second conductive portion 52. With the above structure, in the closed and sealed state, when the superconducting element is energized, a magnetic field that attracts the first magnetic component 4 is generated, thereby tightly sealing the door body 2 and the sealing component 3. When it is necessary to open the door, the superconducting element is de-energized, and the first magnetic component 4 falls under its own weight, which can drive the sealing component 3 to retract downward, thereby canceling the seal with the lower surface of the door body 2. The operation is convenient and reliable.

[0032] In this embodiment, when the door is closed, a gap 20 is formed between the lower surface of the door 2 and the support platform to allow the humid and hot steam after washing to escape. The height of this gap 20 is lower than the height of the upward extension of the sealing member 3. The water tank type washing machine is:

[0033] (1) When closing the door, first flip the door body 2 down to close the opening 11, then run the drive mechanism to drive the sealing element 3 to extend upward and press against the lower surface of the door body 2.

[0034] (2) When the door needs to be opened after washing, the drive mechanism drives the seal 3 to retract downward and separate from the lower surface of the door 2, exposing the gap so that the hot and humid air in the sink body can be discharged after washing.

[0035] (3) After the exhaust is complete, simply flip the door 2 upwards.

[0036] By adopting the above door opening process, the hot and humid air after hot water washing can be avoided from hitting the user's face and causing burns, thus providing safety and a better user experience.

[0037] Example 2:

[0038] The difference between this embodiment and Embodiment 1 is that: Figure 5 As shown, the second magnetic element 5 is disposed below the support 12 and is arranged opposite to the first magnetic element 4. In the conductive state, a magnetic field that can generate a repulsive force on the first magnetic element 4 is formed between the first conductive part and the second conductive part.

[0039] The specification and claims of this invention use terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," to describe various exemplary structural parts and elements of the invention. However, these terms are used herein merely for ease of explanation and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this invention can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be considered as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
