Description

Technical Field

[0001] This invention relates to the field of kitchen cleaning equipment, specifically a cleaning machine. Background Technology

[0002] A cleaning machine is a device that sprays cold or hot water onto dishes and items to remove dirt adhering to them. A typical cleaning machine mainly includes a body forming a cleaning chamber, a control panel, a water pump for spraying washing water, a rotating spray arm, a waste basket assembly, a drainage assembly, and a heater for generating hot water. Existing cleaning machines generate high-temperature water and steam through the heater during operation; some cleaning machines also have a separate steam generator for auxiliary cleaning to enhance the cleaning effect.

[0003] After the washing machine finishes running, you need to take out the tableware. Since the washing has just ended, a lot of hot air will escape from the door gap the moment you open the door, which can easily cause burns. Some users also open the door to put in more tableware during the washing process, and the splashing of hot washing water at this time can also easily cause burns.

[0004] To address the aforementioned technical issues, the applicant's prior application disclosed "A Ventilation Mechanism for a Water Tank Washing Machine," patent number CN201710607205.X (publication number CN108056722A). In this water tank washing machine, fluids such as steam in the water tank body can be discharged outside the water tank body through a vent. The amount of exhaust can be adjusted by the sliding amount of a steam blocking component adapted to the vent relative to the vent, so that the fluid in the washing space is gradually discharged to the exhaust environment located outside the vent. In this way, when the washing machine needs to discharge high-temperature steam, the steam can be discharged from the vent first, reducing the large area of ​​steam hitting the user. At the same time, the steam discharge speed can be adjusted, effectively avoiding safety accidents caused by steam injuring the user.

[0005] While the aforementioned cleaning machines can reduce steam from hitting users to some extent, they essentially prioritize the discharge of some steam to reduce the overall amount of steam discharged. At the moment the door is opened, there is still some residual steam that can cause burns. Furthermore, this structure cannot prevent water and steam from splashing out when the door is opened midway. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a cleaning machine that can prevent steam from escaping to the user when the door is opened and at the same time avoid the splashing of cleaning water, in light of the current state of the technology.

[0007] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a cleaning machine, comprising:

[0008] The cabinet has a hollow interior forming a washing chamber, which also has an opening for taking out and putting in tableware;

[0009] The door has a first side and a second side arranged opposite to each other, wherein the first side is rotatably constrained to a first edge at the opening of the box, so that the second side moves closer to or away from the second edge of the opening, thereby correspondingly closing or opening the opening;

[0010] A blocking mechanism, disposed on the housing and arranged adjacent to the second edge of the opening, has a baffle that is at least partially movable in the opening and closing direction of the second side of the door. When the door is rotated to the state where the second side is away from the second edge of the opening and the opening is opened, the baffle can move accordingly toward the second side of the door, thereby being located on the fluid escape path between the opening and the second side of the door.

[0011] The door can have different opening and closing mechanisms, such as a top-opening door. Preferably, the box is arranged vertically and has the opening on its front side. The lower and upper sides of the door correspond to the first and second sides, respectively. The blocking mechanism is arranged adjacent to the upper edge of the opening.

[0012] The movement of the baffle can be driven by a separate drive mechanism. Preferably, the baffle is an elastic sheet, with one end fixed to the upper edge of the opening and the other end free. The free end of the elastic sheet can move relative to its fixed end, causing the entire elastic sheet to elastically expand or contract. When the door is open, the elastic sheet expands to between the upper edge of the opening and the upper side of the door. This inherently elastic design allows the baffle to automatically and quickly pop out when moisture needs to be blocked, simply by opening the door. No separate drive mechanism is required, eliminating any delay and providing immediate protection for the user.

[0013] To ensure the fixation of the elastic sheet, preferably, the housing has a forward-facing mounting groove at the upper edge of the opening. The blocking mechanism also includes a fixing seat, which is disposed in the mounting groove. The fixed end of the elastic sheet is connected to the fixing seat, and under the action of external force, the elastic sheet can elastically contract into the mounting groove; while under the action of external force removal, the elastic sheet can elastically expand to extend out of the mounting groove.

[0014] In order to ensure both elasticity and ease of folding, preferably, the elastic sheet has at least two creases, and the extension direction of each crease intersects the contraction direction of the elastic sheet.

[0015] To prevent the elastic sheet from becoming unstable after being folded and to avoid noise and vibration, the blocking mechanism preferably includes a movable seat connected to the free end of the elastic sheet. When the elastic sheet expands or contracts elastically, the movable seat is located outside the mounting groove or retracted into the mounting groove.

[0016] The folding of the elastic sheet can be achieved manually or by a separate drive mechanism. Preferably, the movable seat is arranged on the rotation path of the door when it is opened and closed. When the door is in the closed / open state, the elastic sheet acts on the movable seat so that the movable seat always tends to extend outward and abut against the door. This arrangement of the movable seat allows for automatic elastic compression of the elastic sheet when the door is closed, causing it to automatically fold into the aforementioned mounting groove.

[0017] To ensure sufficient storage space between the fixed base and the movable base, preferably, the cross-section of both the fixed base and the movable base is a U-shaped structure with open ends, and the openings of the two are opposite to each other, with the two ends of the elastic sheet located at the corresponding openings.

[0018] To ensure support for the elastic sheet and to ensure that its contraction and expansion are completed along a fixed path, preferably, the blocking mechanism further includes a support rod. The support rod is arranged above or below the elastic sheet, and its inner end is rotatably constrained to the fixed seat, while its outer end is rotatably connected to the movable seat. Under the movement of the elastic sheet, it can be retracted into the mounting groove or partially located outside the mounting groove. When the support rod is retracted into the mounting groove, its extension direction intersects with the movement direction of the elastic sheet; while when the support rod is extended, its extension direction is consistent with the movement direction of the elastic sheet.

[0019] Specifically, the fixed seat has a ball head seat on the side wall adjacent to the mounting groove, the inner end of the support rod has a ball head, and the support rod is constrained on the fixed seat by the rotational engagement of the ball head and the ball head seat.

[0020] Furthermore, the movable seat has a connecting rod extending toward the fixed seat, and the outer end of the support rod is provided with a rotating joint for rotatably connecting to the connecting rod.

[0021] To prevent the barrier from being accidentally triggered when taking out or placing tableware or other items that do not require obstruction, the blocking mechanism preferably includes a limiting member. This limiting member has a limiting piece that can enter the moving path of the movable seat. When the door is in a closed open state, the limiting piece can act on the movable seat to restrict the movable seat from extending outward from the mounting groove.

[0022] Specifically, the limiting member is arranged above the blocking mechanism, and the top of the movable seat is provided with a limiting opening for the lower end of the limiting piece to be locked.

[0023] To achieve locking when the door is opened and closed, preferably, a latch is provided on one of the upper edges of the door and the opening, and a bolt is provided on the other. The door is locked by the bolt and the latch when the opening is closed.

[0024] To ensure that all parts of the opening facing the user can be shielded from high-temperature moisture the moment the door is opened, preferably, the latch is located in the middle of the upper edge of the opening, and the blocking mechanism is located on at least one of the two sides of the latch.

[0025] To prevent leakage from the gap between the two baffles, the blocking mechanism preferably also has a wing plate that is movably constrained between the fixed seat and the movable seat, and has a first use state in which it is retracted into the mounting groove and a second use state in which it extends out of the mounting groove and is located next to the elastic plate. The wing plate is in the first use state when the elastic plate is in an elastically expanded state.

[0026] Specifically, the two ends of the wing plate are rotatably connected to the fixed seat and the movable seat, respectively, and when the wing plate is in the second use state extending to the side of the elastic sheet, the wing plate is at least partially located on the latch.

[0027] To ensure the blocking of the locked area of ​​the door, preferably, the blocking mechanisms on both sides of the latch have wing plates, and when the elastic sheet is in an elastically expanded state, the two adjacent wing plates at least partially overlap above the latch.

[0028] Compared with the prior art, the advantages of the present invention are as follows: In this cleaning machine, by arranging a blocking mechanism on the second edge of the opening near the casing, the baffle in the blocking mechanism can move to the fluid escape path between the opening and the second side of the door when the door is open. In this way, when the user opens the door, the baffle can block most of the hot steam and the reduced hot water, thus preventing the user from being scalded. Attached Figure Description

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] like Figures 1 to 6 The image shows a preferred embodiment of the present invention. In this embodiment, the washing machine includes a housing 1, a door 2, and a blocking mechanism 3. The housing 1 is hollow inside to form a washing chamber 11, which also has an opening 10 for taking out and placing tableware. During washing, the washing chamber 11 needs to form a relatively sealed space from the outside, so a door 2 is usually provided at the opening 10. The door 2 and the housing 1 can have different connection forms, such as a top-opening door, as seen in dishwashers, which are commonly found in sink dishwashers. It can also be a side-opening door, commonly found in built-in dishwashers, freestanding dishwashers, etc. Regardless of the opening method, the door 2 will have a first side and a second side arranged opposite to each other, wherein the first side is rotatably constrained to the first edge of the opening 10 of the housing 1, so that the second side moves closer to or away from the second edge of the opening 10, thereby correspondingly closing or opening the opening 10. The dishwasher in this embodiment is either freestanding or built-in. The cabinet 1 is arranged vertically and has an opening 10 on its front side. The lower and upper sides of the door 2 correspond to the first and second sides mentioned above, respectively.

[0037] In this embodiment, the blocking of high-temperature water vapor at the moment of door opening is achieved by the blocking mechanism 3. The high-temperature water vapor mentioned here includes, but is not limited to, high-temperature cleaning water splashed during cleaning, or high-temperature water vapor; for the sake of brevity, it will be referred to as water vapor or high-temperature water vapor. The blocking mechanism 3 is disposed on the housing 1 and arranged near the second edge of the opening 10. It has a baffle that can reciprocate at least partially in the opening and closing direction of the second side of the door 2. When the door 2 is rotated to the point where the second side is away from the second edge of the opening 10 and the opening 10 is opened, the baffle can correspondingly move towards the second side of the door 2, thereby being located on the fluid escape path between the opening 10 and the second side of the door 2. In this embodiment, the blocking mechanism 3 is specifically arranged near the upper edge of the opening 10.

[0038] The reciprocating extension and retraction of the aforementioned baffle can be driven by a driver to actively move in or out. However, regardless of the driving structure used, there will be a certain time difference between signal acquisition and driver execution, which will eventually cause the baffle to fail to block water vapor immediately. Therefore, the baffle in this embodiment is an elastic sheet 31. One end of the elastic sheet 31 is fixed to the upper edge of the opening 10, and the other end is a free end. The free end of the elastic sheet 31 can move relative to its fixed end, so that the elastic sheet 31 as a whole undergoes elastic expansion or elastic contraction. When the door 2 is open at the opening 10, the elastic sheet 31 elastically expands to between the upper edge of the opening 10 and the upper side of the door 2. Specifically, the aforementioned housing 1 has a forward-facing mounting groove 12 at the upper edge of the opening 10. The blocking mechanism 3 also includes a fixing seat 32, which is disposed in the mounting groove 12. The fixed end of the elastic piece 31 is connected to the fixing seat 32. Under the action of external force, the elastic piece 31 can elastically contract into the mounting groove 12; while under the action of external force removal, the elastic piece 31 can elastically expand to extend out of the mounting groove 12.

[0039] To facilitate folding and prevent the folded elastic sheet 31 from occupying too much space, the elastic sheet 31 has at least two creases, with the extension direction of each crease intersecting the contraction direction of the elastic sheet 31. Furthermore, the blocking mechanism 3 also includes a movable seat 33, which is connected to the free end of the elastic sheet 31. When the elastic sheet 31 expands or contracts elastically, the movable seat 33 is positioned outside or inside the mounting groove 12. The movable seat 33 is also arranged along the rotation path of the door 2 during opening and closing. When the door 2 is in the closed opening 10 state, the elastic sheet 31 acts on the movable seat 33, ensuring that the movable seat 33 always tends to extend outwards and abut against the door 2. This design of the movable seat 33 serves two purposes. First, when the elastic sheet 31 is in an elastically contracted state and folded into the mounting groove 12, the movable seat 33 provides good guidance and fixation at its outer end, preventing unnecessary vibration and noise from the elastic sheet 31 during the operation of the cleaning machine. Second, the movable seat 33 is located on the closing path of the door 2, eliminating the need for a separate drive mechanism or manual closing. The closing force of the door 2 is sufficient to fold the entire elastic sheet 31 into the mounting groove 12, which is very convenient. Furthermore, to ensure sufficient storage space within the mounting groove 12, both the fixed seat 32 and the movable seat 33 have a U-shaped cross-section with open ends, and their openings face each other, with the two ends of the elastic sheet 31 located at corresponding openings.

[0040] The blocking mechanism 3 in this embodiment also includes a support rod 34. The support rod 34 is arranged above or below the elastic plate 31, and its inner end is rotatably constrained to the fixed seat 32, while its outer end is rotatably connected to the movable seat 33. Under the movement of the elastic plate 31, it can be retracted into the mounting groove 12 or partially located outside the mounting groove 12. When the support rod 34 is retracted into the mounting groove 12, its extension direction intersects the movement direction of the elastic plate 31; when the support rod 34 is extended, its extension direction is consistent with the movement direction of the elastic plate 31. Specifically, the fixed seat 32 is provided with a ball head seat 321 on the side wall adjacent to the mounting groove 12, and the inner end of the support rod 34 is provided with a ball head 34a. The support rod 34 is constrained to the fixed seat 32 by the rotational engagement of the ball head 34a and the ball head seat 321. The aforementioned movable seat 33 has a connecting rod 331 extending toward the fixed seat 32, and the outer end of the support rod 34 is provided with a rotating joint 34b for rotatably connecting to the connecting rod 331.

[0041] To prevent the elastic piece 31 from being triggered when no obstruction is needed, the aforementioned blocking mechanism 3 also includes a limiting member 35. This limiting member 35 has a limiting piece 351 that can enter the moving path of the movable seat 33. When the door 2 is in the closed opening 10 state, the limiting piece 351 can act on the movable seat 33 to restrict the movable seat 33 from extending outward from the mounting groove 12. In this embodiment, the limiting member 35 is arranged above the blocking mechanism 3, and the top of the movable seat 33 has a limiting opening 332 for the lower end of the limiting piece 351 to be engaged.

[0042] Furthermore, to ensure that the door 2 can be locked when the opening 10 is closed, a latch 13 is provided on one of the upper edges of the door 2 and the opening 10, and a latch 21 is provided on the other. The door 2 is locked by the latch 21 and the latch 13 when the opening 10 is closed. Specifically, the latch 21 is located in the middle of the upper edge of the opening 10, and the blocking mechanism 3 is located on at least one of the two sides of the latch 21. In order to prevent moisture from leaking from the area where the latch 13 and the latch 21 are located, the blocking mechanism 3 also has a wing plate 36. The wing plate 36 is movably constrained between the fixed seat 32 and the movable seat 33, and has a first use state in which it is retracted into the mounting groove 12 and a second use state in which it extends out of the mounting groove 12 and is located next to the elastic sheet 31. When the elastic sheet 31 is in an elastically expanded state, the wing plate 36 is in the first use state. In this embodiment, the two ends of the wing plate 36 are rotatably connected to the fixed base 32 and the movable base 33, respectively. In the second use state where the wing plate 36 extends to the side of the elastic piece 31, the wing plate 36 is at least partially located above the latch 13. Furthermore, the blocking mechanisms 3 on both sides of the latch 13 each have a wing plate 36, and when the elastic piece 31 is in an elastically expanded state, two adjacent wing plates 36 at least partially overlap above the latch 13.

[0043] Furthermore, 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.
