Description

Technical Field

[0001] This invention belongs to the field of household appliance technology, specifically relating to a sink-type washing machine that can wash dishes and / or fruits and vegetables. Background Technology

[0002] Existing water tank cleaning machines typically consist of a water tank body, a door located at the top of the water tank body, and spray arms. When the cleaning machine is spraying, the door is closed. During drying, the water vapor inside the water tank needs to be discharged through another opening, or a top-mounted motor can be added to open the door and allow the water vapor to escape.

[0003] Specifically, the utility model patent "Ventilation Mechanism of a Water Tank Washing Machine" (authorization announcement number CN 207575123U), with patent number 201720909535.X, includes a water tank body with a washing space inside and an open top; a cover plate, movably disposed on the top of the water tank body, with a vent section partially communicating with the washing space. A steam blocking component is adapted to the vent section, and an actuator is also included. When the cover plate is opened to a small angle, the actuator drives the steam blocking component to open relative to the vent section. Therefore, regardless of how the user opens the cover plate, the hot air after washing can first be discharged through the vent section, thus protecting the user's safety.

[0004] However, the above solution requires opening a vent on the cover plate and adding actuators, making the overall structure more complex and costly. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide a water tank type cleaning machine that can achieve exhaust without the need for a separate ventilation structure, and does not affect the cleaning operation of the cleaning machine.

[0006] The second technical problem to be solved by the present invention is to provide a water tank type cleaning machine that avoids splashing of spray water while not affecting exhaust.

[0007] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a water tank type cleaning machine, comprising:

[0008] The water tank body has a hollow interior forming a cleaning chamber with an open top; the open top has a first edge and a second edge, and the arrangement direction between the first edge and the second edge is defined as the first direction;

[0009] The door, with its bottom facing down, is placed over the opening of the water tank body to close the opening;

[0010] Its features are:

[0011] The portion of the door near the first edge of the opening is composed of at least two plates arranged side by side along the first direction, with a gap between adjacent plates, the gap connecting the cleaning chamber to the outside.

[0012] In this way, the heat inside the tank can be discharged through the gaps. Since the gaps are relatively close to the first edge of the opening and located between two adjacent panels, the spray water during the cleaning machine's spraying operation is difficult to splash out through the gaps. That is, the panels will block the spray water from flowing upwards, and the spray water can flow down along the side of the panels.

[0013] To enable the opening and closing of the opening, preferably, the door is movable back and forth along the first direction at the opening of the water tank body, and has a first state of closed opening and a second state of open opening offset to the first edge. When the cleaning machine finishes working, in order to accelerate the discharge of hot air, the door can be moved a small distance to expose part of the opening, and the hot air can be discharged directly through the opening.

[0014] Preferably, the door is a roller shutter door and has a first free end, which can move back and forth along the first direction under the action of external force. In the second state, the roller shutter door is rolled up to the first edge side, and the first free end of the roller shutter door is relatively far away from the second edge of the opening. In the first state, the first free end of the roller shutter door is close to the second edge of the opening, so that the roller shutter door is unfolded on the opening. In this way, the door can be fully opened, and since the roller shutter door is rolled up to the first edge side, it occupies less space.

[0015] Preferably, the entire door body is composed of multiple of the aforementioned plates arranged side by side, and each plate extends along a second direction that intersects the aforementioned first direction. Adjacent plates are arranged to rotate around an axis extending along the second direction between them, so that the entire door body can be rolled up or unfolded under the action of external force.

[0016] Furthermore, in the open and closed state, the door body has a flat section that lies flat on the open and extends from the second edge of the open toward the first edge, and a curved section that bends downward from the portion of the flat section near the first edge, wherein at least two adjacent panels at the junction of the flat section and the curved section are provided with the aforementioned gap.

[0017] Furthermore, the panels in the flat section are arranged continuously along the first direction mentioned above, with the sides of adjacent panels facing each other and adhering to each other. Thus, the entire flat section is an airtight flat plate. That is, the roller shutter door structure of the door in this invention, combined with the movement of the door, allows a gap to be naturally formed when the door is closed or open.

[0018] In the above-mentioned scheme, preferably, it also includes a roller shutter box, which is located on the outer side wall of the first edge of the water tank body, and has a hollow cavity inside, with an opening at the top of the cavity for the roller shutter door to pass through; in the second state, at least part of the roller shutter door is rolled up in the roller shutter box.

[0019] In this way, the roller shutter box can roll up and accommodate the roller shutter door.

[0020] Furthermore, during the operation of the cleaning machine, spraying and steam heat treatment are carried out, which may result in water being sprayed onto the door and hot steam condensing on the door. Therefore, after the cleaning machine finishes its operation, there is often water on the door. The combination of the roller shutter door and the roller shutter box in this invention can collect the water on the door into the roller shutter box.

[0021] Preferably, the bottom wall of the roller shutter box is provided with a drain outlet, which is connected to the cleaning chamber. In this way, water inside the roller shutter box can be drained into the cleaning chamber.

[0022] To further improve breathability, preferably, in the first state, a portion of the door is located within the opening, and a second gap is left between the top surface of the door and the first edge of the corresponding opening, thereby allowing the cavity inside the roller shutter box to connect with the outside. Furthermore, the bottom surface of the door is simultaneously positioned vertically opposite the first edge of the opening and the second edge of the corresponding opening, thus connecting the washing chamber of the sink body with the cavity inside the roller shutter box. In this way, when the door is closed, the hot air inside the sink body can still be discharged through the opening of the roller shutter box.

[0023] Preferably, the side wall of the cavity of the roller shutter box is provided with a guide rail, which extends vertically in at least a portion, and the roller shutter door is constrained within the roller shutter box in a manner that allows it to move along the guide rail.

[0024] In order to achieve better retraction, the guide rail is preferably U-shaped as a whole, and in the second state, at least a portion of the roller shutter door is retracted into a U-shape.

[0025] To further solve the second technical problem mentioned above, preferably, it also includes a substrate, which is disposed below the door and constrained together with the door. The top surface of the substrate and the bottom surface of the door are spaced apart to form a cavity. The substrate has air holes that penetrate its own thickness. In the open and closed state, the air holes are opposite to and connected to the cleaning chamber mentioned above.

[0026] The substrate is arranged to bend and deform accordingly as the door retracts or unfolds.

[0027] Thus, when the door is closed, the base plate blocks the bottom of the door, preventing water spray. Hot air can escape through the pores and cavities on the base plate. Even if a small amount of water sprays into the cavity through the pores, it cannot rise through the gap. Furthermore, when part of the door is rolled up into the roller shutter box, water entering the cavity can be drained into the roller shutter box.

[0028] To further prevent water from splashing out, preferably, when the opening is closed, the air holes are located diagonally below the aforementioned gap and are offset from each other.

[0029] Preferably, there are multiple pores, which are spaced apart on the substrate.

[0030] To prevent spray water from entering the cavity through the air holes, preferably, the two opposite edges of the air holes extend upward to form baffles, the baffles extend into the cavity, and the two baffles are spaced apart to form a first gap, the top of the first gap is closed, and the side of the first gap is open and connected to the cavity.

[0031] In the above schemes, the first direction can be the front-back direction or the left-right direction, etc. Preferably, the first edge and the second edge of the opening are arranged one in front and one behind, that is, the first direction is the front-back direction.

[0032] Preferably, the system further includes a hot air device capable of generating hot air, constrained within the water tank body, and the air outlet of the hot air device is connected to the cleaning chamber of the water tank body. In this way, the hot air generated by the hot air device can dry the interior of the water tank body, and the water vapor generated during drying can be discharged through the gaps in the door, which helps to improve the drying effect.

[0033] Preferably, an air inlet is provided on the left or right side wall of the water tank body, the hot air device is located outside the water tank body, and the air outlet of the hot air device is connected to the air inlet.

[0034] Compared with the prior art, the advantages of the present invention are as follows: by designing the part of the door body near the first edge of the opening to be composed of at least two plates arranged side by side along the first direction, and forming a gap between the two adjacent plates, the gap connects the cleaning chamber to the outside. In this way, the hot air in the water tank body can be discharged through the gap. Since the gap is relatively close to the first edge of the opening and is located between the two adjacent plates, the spray water generated during the spraying operation of the cleaning machine is difficult to splash out through the gap. That is, the plate will block the spray water from flowing upward, and the spray water can flow down along the side of the plate. Attached Figure Description

[0040] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0041] like Figures 1-5 As shown, this is a preferred embodiment of a water tank type cleaning machine of the present invention. The water tank type cleaning machine includes a water tank body 1, a door body 2, a roller shutter box 4, a base plate 4, and a hot air device 7.

[0042] The water tank body 1 has a hollow interior forming a cleaning chamber with an opening 10 at the top. The opening 10 has opposing first edges 11 and second edges 12, and the arrangement direction between the first edges 11 and second edges 12 is defined as the first direction. In this embodiment, the first edges 11 and second edges 12 of the opening 10 are arranged one in front of the other, i.e., the first direction is the front-back direction. The opening 10 also has left and right edges extending front-back. An air inlet 13 is provided on the left or right side wall of the water tank body 1.

[0043] The aforementioned roller shutter box 4 is located near the first edge 11 on the rear side of the water tank body 1, and has a hollow interior forming a cavity 40. The top of the cavity 40 has an opening 41. The bottom wall of the cavity 40 has a drain outlet 43, which communicates with the washing chamber. Meanwhile, the left and right side walls of the cavity 40 are each provided with a guide rail 42. Each guide rail 42 is U-shaped, having a vertical section 42a arranged one in front of the other and an arc-shaped section 42b connecting the lower ends of the two vertical sections 42a. Additionally, the guide rail 42 also has a horizontal section 42c extending forward from the upper end of the rear vertical section 42a along the edge of the opening 10.

[0044] The aforementioned door 2 is movably positioned at the opening 10 of the water tank body 1 in a first direction, and has a first state in which the bottom surface faces downwards, covering the opening 10 and closing the opening 10 (e.g., Figures 1-3 As shown), and the second state in which the opening 10 is opened by being offset to the side of the first edge 11 (as shown). Figure 4 , 5(As shown). In this embodiment, the door 2 is a roller shutter door, with its left and right sides respectively constrained to corresponding guide rails 42 so that it can move along the guide rails. The door 2 has a first free end 21, which can move back and forth in the first direction under the action of external force. In the second state, the left and right sides of the roller shutter door move along the guide rails 42 and partially roll up into a U-shape, and are located inside the roller shutter box 4. The first free end 21 of the roller shutter door is relatively far away from the second edge 12 of the opening 10 and is exposed on the front side of the opening 41 of the roller shutter box 4. In the first state, the first free end 21 of the roller shutter door is close to the second edge 12 of the opening 10, so that the roller shutter door is unfolded on the opening 10. At this time, the second free end of the roller shutter door opposite to the first free end 21 is located inside the opening 41 of the roller shutter box 4. A second gap 411 is left between the top surface of the roller shutter door and the first edge of the corresponding opening 41, so that the cavity 40 inside the roller shutter box 4 is connected to the outside.

[0045] In this embodiment, the door 2 is composed of multiple strip-shaped panels 20 arranged side by side, each panel 20 extending along a left-right direction intersecting the first direction. Adjacent panels 20 are arranged to rotate around an axis extending along a second direction between them, allowing the entire door 2 to roll up or unfold under external force. When the opening 10 is closed, the door 2 has a flat section 2a extending from the second edge 12 of the opening 10 towards the first edge 11, and a curved section 2b bending downwards from the portion of the flat section 2a near the first edge 11. At least two adjacent panels 20 at the junction of the flat section 2a and the curved section 2b form a gap 200 near the first edge 11 of the opening 10, connecting the cleaning chamber to the outside. In the flat section 2a, the panels 20 are continuously arranged along the first direction, with the sides of adjacent panels 20 facing each other and fitting together. See details... Figure 2 .

[0046] The aforementioned substrate 6 is located below the door body 2 and is constrained to it, and can undergo corresponding bending deformation as the door body 2 rolls up or unfolds. The substrate 6 can be made of flexible fabric or a roller shutter structure similar to that of the door body 2. A cavity 22 is formed between the top surface of the substrate 6 and the bottom surface of the door body 2. An air hole 60 penetrating the thickness of the substrate 6 is provided on the substrate 6. When the opening 10 is closed, the air hole 60 is located obliquely below the aforementioned gap 200 and is staggered with each other. The air hole 60 is opposite to and connected to the aforementioned cleaning chamber. In this embodiment, there are multiple air holes 60, which are distributed at intervals on the substrate 6. Furthermore, the two opposing edges of each air hole 60 extend upward to form a baffle 61, which extends into the cavity 22. The two baffles 61 are spaced apart to form a first gap 610. The top of the first gap 610 is closed to prevent the spray water from flowing upward, while the side of the first gap 610 is open and communicates with the cavity 22, allowing hot air to enter the cavity 22. Simultaneously, in the first open-closed state, the rear side of the cavity 22 is open and communicates with it, allowing hot air from the cavity 22 to enter the roller shutter box 4 and exit through the second gap 411. Also, in this embodiment, in the first open-closed state, the bottom surface of the substrate 6 is simultaneously positioned one above the other, with the first edge 11 of the opening 10 and the second edge 412 of the corresponding opening 41 positioned one above the other, thus connecting the cleaning chamber of the water tank body 1 with the cavity 40 inside the roller shutter box 4.

[0047] The aforementioned hot air device 7 is existing technology. It is confined outside the water tank body 1, and the air outlet of the hot air device 7 is connected to the air inlet 13 of the water tank body 1, thereby enabling the delivery of hot air to the inside of the water tank body 1.

[0048] In this embodiment, when the cleaning machine is working, the hot air in the water tank body 1 can either directly enter the roller shutter box 4 through the gap between the first edge 11 of the base plate 6 and the opening 10 and the second edge 412 of the corresponding opening 41, and be discharged through the second gap 411; or enter the cavity 22 through the air hole 60 on the base plate 6. Part of the hot air in the cavity 22 is discharged directly through the gap 200, and the other part enters the roller shutter box 4 and is discharged through the second gap 411.

[0049] After the cleaning machine finishes its work, the condensate on the bottom surface of the base plate 6 can be collected into the roller shutter box 4 as the door 2 opens, and then return to the water tank body 1 from the drain outlet 43.
