Description

Technical Field

[0001] This invention belongs to the field of tableware processing, and more specifically, relates to a dishwasher door structure and a dishwasher. Background Technology

[0002] In existing technology, traditional dishwashers typically use a single-door design, requiring users to fully open the door to load and unload dishes. This design excels in scenarios requiring the washing of large quantities of dishes, as it provides ample space for convenient user operation.

[0003] However, the full-door design becomes less flexible when only a small number of dishes need to be washed or when adding dishes mid-cycle. Firstly, when only the top shelf of the dishwasher is needed, the large door size requires the user to bend over to open and close it. Secondly, whether initially placing dishes or adding them mid-cycle, the user can only open the entire door, making it impossible to access shelves within the dishwasher's interior.

[0004] To address the aforementioned issues, existing technology has developed a design that divides the dishwasher door into two sections. This design typically includes a main door and a secondary door that separates from the main door at its upper or lower portion. The secondary door can open and close independently or be locked to the main door to form a single, integrated door, opening and closing together with the main door. This configuration enhances the dishwasher's usability, allowing users to choose to open the entire door or only the secondary door as needed.

[0005] However, this double-door design also presents new problems. When the secondary door is open, food residue can easily fall through the gap onto the main door below it. When the secondary door is closed, this residue gets stuck between the bottom of the secondary door and the main door, causing residue to accumulate in the gap and potentially affecting the dishwasher door's sealing performance.

[0006] In view of this, the present invention is proposed. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art. The purpose is to provide a door structure for a dishwasher that, when the secondary door opens the loading and unloading opening of the main door, the rotation of the secondary door can cause the blocking component to flip and block the main door below the loading and unloading opening, thereby preventing the residue inside the dishwasher from entering the gap area between the bottom of the secondary door and the main door below it after the secondary door is opened.

[0008] Another object of the present invention is to provide a dishwasher.

[0009] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is to provide a door structure for a dishwasher, comprising:

[0010] The main door body is provided with an opening for taking out and putting in items;

[0011] The secondary door body is rotatably mounted on the main door body for opening and closing the retrieval opening, and forms an integral door structure with the main door body when the retrieval opening is closed;

[0012] A shielding component is disposed between the main door body and the secondary door body, and after the secondary door body is flipped open, it at least shields the portion of the main door body below the retrieval opening.

[0013] Furthermore, the shielding component is retractably disposed between the secondary door and the main door, extending downward from the secondary door through the gap between the bottom of the secondary door and the main door;

[0014] Preferably, the shielding component is provided to extend laterally along the pick-up and put-out opening.

[0015] Furthermore, the two ends of the shielding component are respectively connected to the inner sidewalls of the secondary door and the main door below the retrieval opening, and are extended and retracted as the secondary door is flipped.

[0016] When the secondary door is opened, the shielding component unfolds to cover the gap between the bottom wall of the secondary door and the inner side of the main door; when the secondary door is closed, the shielding component retracts, close to the inner side of the door structure, and covers the gap between the bottom of the secondary door and the main door.

[0017] Furthermore, the shielding component includes a shielding member, which is rollable or foldable and stored on the secondary door body and / or the main door body;

[0018] Alternatively, the shielding component includes a plurality of shielding members nested sequentially in the vertical direction, with the shielding members at both ends of the telescopic direction of the shielding component being connected to the secondary door body and the main door body, respectively.

[0019] After the secondary door is opened, the shielding member extends to cover the top of the main door below the retrieval opening.

[0020] Furthermore, the shielding component also includes a mounting base, which is disposed on the inner sidewall of the secondary door body and / or the main door body;

[0021] One or both ends of the shielding member may be wrapped around the mounting base, or may be folded and disposed in the receiving cavity of the mounting base.

[0022] Furthermore, one end of the shielding member is fixedly disposed on the upper or lower part of the inner side wall of the secondary door body, the mounting base is disposed on the inner side wall of the main door body below the retrieval opening, and the other end of the shielding member is wrapped around the mounting base.

[0023] Furthermore, the two ends of the shielding component are respectively connected to the splicing surfaces of the secondary door and the main door. When the secondary door is closed, it is sandwiched between the bottom wall of the secondary door and the main door below the retrieval opening. After the secondary door is flipped open, it unfolds to cover the main door below the retrieval opening.

[0024] Furthermore, the shielding component folds or elastically retracts when the secondary door is closed and is sandwiched between the splicing surfaces of the secondary door and the main door.

[0025] Furthermore, the shielding member includes a shielding curtain that is wrapped around at least one end, or the shielding member includes a shielding curtain that is elastically telescopic; or it can be foldably disposed on the shielding curtain.

[0026] Preferably, the blind curtain is a mesh curtain or a blind sheet.

[0027] The present invention also provides a dishwasher having any of the door structures described above.

[0028] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0029] (1) The present invention provides a shielding component between the main door and the secondary door. When the secondary door is flipped open, the shielding component automatically unfolds and at least covers the part of the main door below the loading and unloading opening, thereby effectively preventing debris from falling in. This maintains the flexibility and ease of use of the dishwasher door structure, reduces the maintenance and cleaning costs of the dishwasher, and improves the user experience of the dishwasher.

[0030] (2) The shielding member is provided on the inner side wall of the sub-door body along the lateral extension of the pick-up and put-out opening. The shielding member can completely cover the gap between the bottom of the sub-door body and the main door body when the sub-door body is closed.

Therefore, they should not be construed as limiting this invention.

[0052] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0053] like Figures 1 to 8 As shown, the present invention provides a door structure 1 for a dishwasher, the door structure 1 being used to close or open the opening of the washing chamber 3 of the dishwasher, forming a closed washing chamber 3 for operation. In this embodiment of the invention, the door structure 1 is installed on the dishwasher, with the side facing the washing chamber 3 as the inner side and the side facing the user as the outer side.

[0054] like Figures 1 to 2 As shown, the door structure 1 includes a main door body 11, a secondary door body 12, and a blocking component 15.

[0055] The main door 11 is provided with a pick-up and drop-off opening 111. The pick-up and drop-off opening 111 is provided on a portion of the main door 11 and extends through the inner and outer sides of the main door 11. The main door 11 can be installed on the body 2 of the dishwasher or on the inner wall of the washing chamber 3, and is used to cooperate with the secondary door 12 to close the opening of the washing chamber 3, providing a closed working space for the dishwasher.

[0056] The secondary door 12 is rotatably mounted on the main door 11 and is used to open and close the retrieval opening 111. When the secondary door 12 is opened, it is placed horizontally. Users can use the open retrieval opening 111 to directly retrieve and place tableware on some shelves inside the washing chamber 3, or slide some shelves out of the washing chamber 3 before retrieving and placing tableware.

[0057] When the secondary door 12 closes the retrieval opening 111, it forms a door structure 1 that is integrated with the main door 11.

[0058] The shielding component 15 is located between the main door body 11 and the secondary door body 12. After the secondary door body 12 is flipped open, it at least shields a portion of the main door body 11 below the retrieval opening 111.

[0059] This invention provides a blocking component 15 between the main door 11 and the secondary door 12. When the secondary door 12 is opened, the blocking component 15 automatically unfolds and at least covers the portion of the main door 11 below the loading / unloading opening 111, effectively preventing debris from falling in. This maintains the flexibility and ease of use of the dishwasher's door structure 1 while reducing maintenance and cleaning costs, thus improving the user experience.

[0060] After the secondary door 12 is closed, the shielding component 15 is positioned close to the inner side of the secondary door 12 to avoid occupying space within the washing chamber 3.

[0061] Furthermore, the blocking component 15 is retractably disposed between the secondary door body 12 and the main door body 11, and extends downward from the secondary door body 12 by a certain distance to cover the gap between the bottom of the secondary door body 12 and the main door body 11, thus blocking the gap after the secondary door body 12 is flipped open. The blocking component 15 retracts when the secondary door body 12 is closed.

[0062] The shielding component 15 may be extended or shortened as a whole along its extension direction, such as the shielding component 15 being an elastic element.

[0063] The shielding component 15 may also have one end retractably mounted on the secondary door body 12 or the main door body 11, and the other end fixedly or retractably mounted on the main door body 11 or the secondary door body 12.

[0064] For example, the lower end of the blocking component 15 is fixed to the main door body 11. The upper end of the blocking component 15 is telescopically oriented. After the secondary door body 12 is closed, it is pressed against the inner wall of the secondary door body 12. After the secondary door body 12 is opened, the blocking component 15 extends to the inner wall of the secondary door body 12, thereby blocking the main door body 11 below the access opening 111.

[0065] The blocking component 15 can also be fixedly connected to the secondary door body 12 and the main door body 11 respectively. For example, when the secondary door body 12 is closed, the blocking component 15 is bent and extended to catch the gap between the secondary door body 12 and the main door body 11 below. The blocking component 15 is a flexible component. When the secondary door body 12 is flipped open, the bent flexible component deforms as the secondary door body 12 opens, blocking the main door body 11 below the retrieval opening 111.

[0066] The secondary door 12 is rotatably mounted on the main door 11 via a hinge or rotating shaft. The retrieval opening 111 is located on the upper part of the main door 11. A handle 123 is provided on the upper part of the secondary door 12, and the secondary door 12 is rotatably mounted on the lower part of the retrieval opening 111. Users can close the secondary door 12 by flipping it upwards and open it by flipping it downwards. When washing a small amount of tableware or adding tableware midway, only the secondary door 12 needs to be opened, thus reducing the space occupied during use. Furthermore, the entire process eliminates the need to bend over to open and close the door, improving the user experience.

[0067] After the secondary door 12 is joined to the main door 11, the inner and outer surfaces of the door structure 1 are coplanar. When the secondary door 12 is locked to the main door 11, the user can close the washing chamber 3 of the dishwasher by lifting the door structure 1.

[0068] The secondary door 12 and the main door 11 are hinged together via a linkage mechanism. All existing hinge structures in household appliances can be applied to the hinged installation of the secondary door 12 in this invention. Specifically, the secondary door 12 can be installed to the main door 11 via a hinge structure 13.

[0069] Furthermore, the blocking component 15 extends and retracts as the secondary door 12 flips. The two ends of the blocking component 15 are respectively connected to the inner sidewalls of the main door 11 below the secondary door 12 and the retrieval opening 111.

[0070] When the secondary door 12 is opened, the shielding component 15 unfolds to cover the gap 116 between the bottom wall of the secondary door 12 and the inner side of the main door 11. When the secondary door 12 is closed, the shielding component 15 is located inside the door structure 1, covering the gap between the bottom of the secondary door 12 and the main door 11.

[0071] The main door body 11 includes a first main door body portion 114 and a second main door body portion 115 arranged vertically. The retrieval opening 111 is provided on the first main door body portion 114 and extends downward to the top of the second main door body portion 115 to form a lower frame 1111. The blocking member 15 at least blocks the lower frame 1111.

[0072] The area enclosed between the top of the lower frame 1111 and the bottom wall of the secondary door 12 is the interval area 116.

[0073] The shielding component 15 includes a shielding member 151. At least one end of the shielding member 151 is disposed on the secondary door body 12, and the other end extends downward through the lower frame 1111 of the retrieval opening 111.

[0074] The shielding member 151 is disposed on the inner side of the secondary door body 12 along the extending direction of the lower frame 1111 of the access opening 111, that is, at the bottom of the secondary door body 12 along the lateral extending direction of the secondary door body 12. The shielding member 151 can completely cover the lower frame 1111 when the secondary door body 12 is closed.

[0075] Specifically, when the secondary door 12 is opened, the obstruction member 151 extends and expands to cover the gap area 116 between the bottom wall of the secondary door 12 and the inner side of the lower frame 1111. When the secondary door 12 is closed, the main door 11 and the secondary door 12 are joined to form a complete door structure 1. The obstruction member 151 then retracts and is positioned close to the inner wall of the door structure 1 to avoid occupying too much space in the washing chamber 3 when the dishwasher is operating.

[0076] One specific scaling solution is, for example, Figures 3 to 6 As shown, the obstruction member 151 is retractable and can be rolled up or folded to be stored on the secondary door body 12 and / or the main door body 11. After the secondary door body 12 is opened, the obstruction member 151 is stretched to cover the interval area 116.

[0077] The shielding component 15 also includes a mounting base 152. The mounting base 152 is disposed on the inner side wall of the secondary door body 12, and / or on the inner side wall of the main door body 11.

[0078] One or both ends of the shielding member 151 may be wrapped around the mounting base 152, and the shielding member 151 covers the gap area 116 between the bottom wall of the sub-door body 12 and the inner side of the lower frame 1111.

[0079] Alternatively, the mounting base 152 may have a receiving cavity (not shown in the figure), and one or both ends of the blocking member 151 may be folded and retracted into the receiving cavity. When the secondary door 12 is opened, the blocking member 151 stored in the receiving cavity moves out of the receiving cavity and unfolds.

[0080] Furthermore, one end of the shielding member 151 is fixedly disposed on the upper or lower part of the inner side wall of the secondary door body 12, the mounting base 152 is disposed on the main door body 11 below the lower frame 1111, and the other end of the shielding member 151 is wrapped around the mounting base 152.

[0081] When one end of the blocking member 151 is fixedly disposed on the lower part of the inner side wall of the secondary door body 12, and the other end of the blocking member 151 is fixedly disposed on the upper part of the second main door body 115 (see...) Figure 3 and Figure 4 This can save space occupied by the shielding component 15.

[0082] When one end of the blocking member 15 is fixed to the upper part of the inner side wall of the secondary door body 12, and the other end of the blocking member 151 is fixedly disposed on the upper part of the second main door body 115 (see...) Figure 5 and Figure 6 This not only blocks the lower frame 1111 when the secondary door 12 is opened, but also blocks the upper side of the horizontally placed secondary door 12, preventing food residue from falling onto the horizontally placed secondary door 12 during the outward pulling of the shelf.

[0083] Another specific scaling solution is, such as Figure 7 As shown, the shielding component 15 includes multiple shielding members 151 that are nested or overlapped in the vertical direction. The shielding members 151 at both ends of the telescopic direction of the shielding component 15 are connected to the secondary door body 12 and the main door body 11, respectively. After the secondary door body 12 is opened, it moves the shielding component 15, causing its multiple shielding members 151 to stretch and lengthen, covering the interval area 116, that is, shielding the lower frame 1111.

[0084] Specifically, the inner wall of the main door 11 is provided with a blocking member 151, which bends upward and extends adjacent to the inner wall of the secondary door 12. The inner wall of the secondary door 12 is provided with a blocking member 151, which bends downward and extends to the inner side of the main door 11. The blocking member 151 on the secondary door 12 is located outside the blocking member 151 on the main door 11, and the two are fastened together. When the secondary door 12 is opened, the blocking member 151 on the secondary door 12 rotates and remains fastened to the blocking member 151 on the main door 11, together covering the interval area 116.

[0085] Another specific telescopic scheme is (not shown in the figure), where the two ends of the blocking member 151 are respectively connected to the splicing surfaces of the secondary door body 12 and the main door body 11, that is, respectively connected to the bottom wall of the secondary door body 12 and the lower frame 1111.

[0086] When the secondary door 12 is closed, the shielding member 151 is sandwiched between the bottom wall of the secondary door 12 and the lower frame 1111, which can play a sealing role between the secondary door 12 and the lower frame 1111. After the secondary door 12 is flipped open, it unfolds to cover the interval area 116.

[0087] The shielding member 151 can be folded or elastically extended.

[0088] When the secondary door 12 is closed, the shielding member 151 folds outward and is sandwiched between the splicing surfaces of the secondary door 12 and the main door 11; when the secondary door 12 is open, the shielding member 151 unfolds to shield the interval area 116.

[0089] When the secondary door 12 is closed, the blocking member 151 rebounds and is sandwiched between the splicing surfaces of the secondary door 12 and the main door 11; when the secondary door 12 is opened, the blocking member 151 is stretched to block the interval area 116.

[0090] In combination with various embodiments of the present invention, the shielding member 151 can be a flexible shielding curtain with at least one end wrapped around it. The shielding member 151 can be wrapped around the mounting base 152. The shielding member 151 can also be an elastically telescopic shielding curtain. The shielding member 151 can also be a foldable shielding curtain, which may not be elastic.

[0091] Preferably, the blind is a mesh curtain or a blind sheet. According to various embodiments of the present invention, it can be configured to be flexible or non-flexible, elastic or inelastic, multi-piece combined for elongation and shortening, etc.

[0092] Furthermore, the inner sidewalls of the main door body 11 and the secondary door body 12 are respectively provided with a first slide rail 113 and a second slide rail 122, and the first slide rail 113 and the second slide rail 122 are spliced ​​together to form a shelf slide rail 18.

[0093] When the secondary door 12 is opened alone, the upper shelf inside the dishwasher can be pulled out to the outside of the washing chamber 3 via the second slide 122. When the secondary door 12 and the main door 11 are opened together, the lower shelf or the entire shelf inside the dishwasher can be pulled out to the outside of the washing chamber 3 via the shelf slide 18.

[0094] When the secondary door 12 is closed, the second slide rails 122 on the left and right sides of the secondary door 12 are respectively sealed and connected to the left and right side frames of the pick-up and put-out opening 111.

[0095] The first slide rail 113 is disposed on the left and right sides of the inner sidewall of the second main door body 115, and the second slide rail 122 is disposed on the left and right sides of the inner sidewall of the secondary door body 12, corresponding to the first slide rail 113 to form two vertically arranged slide rails. The tops of the left and right slide rails of the second slide rail 122 are connected to each other. The second slide rail 122 can be inserted entirely into the retrieval opening 111 to achieve a sealed connection.

[0096] The opposite sidewalls of the second slide rails 122 on the left and right sides of the secondary door 12 are provided with fixing members or mounting seats 152. One end of the blocking member 151 is detachably fixed to the fixing member or wrapped around the mounting seat 152. The fixing member or mounting seat 152 is located near the top of the second slide rail 122, so that when the secondary door 12 is opened, the blocking member 151 can cover the entire inner side of the secondary door 12 of the second slide rail 122, preventing food residue from falling onto the secondary door 12 during the shelf pulling process.

[0097] Alternatively, the blocking member 151 can be folded or extended and clamped between the bottom wall of the secondary door body 12 and the lower frame 1111, as well as between the second slide rail 122 and the first slide rail 113.

[0098] A sealing strip 14 extends from the lower frame 1111 and cooperates with the bottom wall of the secondary door 12 to seal and prevent water leakage after the secondary door 12 and the main door 11 are spliced ​​together into a door structure 1.

[0099] The second slide 122 is also provided with a sealing strip 14, which is sealed to the take-up and put-down opening 111.

[0100] like Figure 8 As shown, the present invention also provides a dishwasher, the dishwasher including any of the door structures 1 and washing chambers 3 described above, the door structure 1 being used to open and close the opening of the washing chamber 3.

[0101] The dishwasher includes a body 2, and the washing chamber 3 is disposed within the body 2. The door structure 1 is rotatably disposed on the body 2 and is used to open or close the opening of the washing chamber 3.

[0102] When the secondary door 12 is opened, the upper or lower part of the opening of the washing chamber 3 can also be opened, and the upper or lower shelf in the washing chamber 3 can be pulled out to take out or put in tableware. When the secondary door 12 is closed, the door structure 1, which is integrated with the main door 11, works together to close the opening of the entire washing chamber 3.

[0103] The dishwasher of the present invention makes it easier for users to load and unload tableware during use, while maintaining the cleanliness and airtightness of the dishwasher.

[0104] like Figures 9 to 16 As shown, the present invention also provides a dishwasher, comprising: a body 2, a washing chamber 3 inside the body 2, and an opening 31 on one side of the washing chamber 3. The opening side of the washing chamber 3 can be located in any of the following directions: up, down, left, right, front, or back. For ease of description in this embodiment, the front side of the dishwasher, which is placed vertically on the ground, is taken as the front side, and the opening 31 of the washing chamber 3 is located on the front side. At the same time, a door structure 1 is installed on the front side of the body 2, which can correspond to the opening and closing of the opening 31 of the washing chamber 3. The door structure 1 can be installed in any existing manner. For ease of description in this embodiment, the door structure 1 is installed in a way that allows it to be flipped open outward via a door hinge.

[0105] In this embodiment of the invention, the dishwasher door structure 1 includes: a main door 11, which constitutes the main body structure of the door structure 1; a portion of the main door 11 is configured as a pick-up and drop-off opening 111, which extends through the front and rear of the main door 11, allowing the user to use the open pick-up and drop-off opening 111 to pick up and drop off some shelves placed in the washing chamber 3; preferably, for ease of user operation, the main door 11 of the door structure 1 can be divided into upper and lower parts, namely a first main door part 114 and a second main door part 115, respectively. The pick-up and drop-off opening 111 is provided on the upper first main door part 114, and a secondary door 12 is correspondingly installed on the upper first main door part 114 of the door structure 1, so that after the secondary door 12 is opened, the user can easily pick up and drop off the upper shelf 61. Of course, the aforementioned secondary door 12 can also be set at any position such as the lower part, left side, or right side of the main door 11.

[0106] In this embodiment of the invention, the secondary door 12 and the main door 11 are connected by an openable and closable structure, so that the secondary door 12 can open or close the retrieval opening 111 on the main door 11. In this embodiment of the invention, for ease of description, the secondary door 12 and the main door 11 are connected by a lower hinge as an example for discussion. Of course, the secondary door 12 and the main door 11 can also be assembled using any other existing structural method.

[0107] With the above configuration, the dishwasher door structure 1 can fully or partially open the opening 31 of the washing chamber 3, so that by installing a single main door 11 on the dishwasher, some or all of the shelves 6 can be accessed and placed separately. At the same time, by installing a secondary door 12 on the main door 11 that can open and close some of the openings 31, the dishwasher can accommodate multiple access and opening / closing methods with only a single door structure 1, thereby effectively simplifying the operation steps of opening and closing the dishwasher door.

[0108] like Figures 9 to 16 As shown in the figure, this embodiment introduces a dishwasher door structure 1, including: a main door 11, used to open and close the opening 31 of the washing chamber 3 of the dishwasher; a portion of the main door 11 is configured as a pick-up and put-away opening 111, which connects the portion of the opening 31 of the washing chamber 3 to the outside; a secondary door 12 is installed on the main door 11, which is used to open and close the pick-up and put-away opening 111; a shelf slide 18 is provided on the secondary door 12, which is used to cooperate with the shelf 6 in the washing chamber 3 to slide outward when the secondary door 12 is opened.

[0109] By setting a shelf slide 18 on the secondary door body 12, when the secondary door body 12 is opened, the added shelf slide 18 can be used to guide and support the shelf 6 that is taken out and put in through the self-access opening 111. This achieves the effect of the shelf 6 entering and exiting through the self-access opening 111 being effectively supported by the secondary door body 12, thereby greatly improving the convenience for users to take out and put in some shelves through the self-access opening 111.

[0110] In this embodiment, the secondary door 12 is hinged to the main door 11 and can be flipped outward. The side of the secondary door 12 facing the washing chamber 3 is the inner side 101, and the shelf slide 18 is provided on the inner side 101. The lower side of the secondary door 12 is connected to the main door 11 via a hinge structure 13 arranged horizontally along the axis. A limiting structure is provided between the secondary door 12 and the main door 11 to keep the secondary door 12 horizontal when it is flipped outward to the open position. The shelf slide 18 is provided on the upper side of the secondary door 12 when it is in the open position. When the secondary door 12 is in the open position, the shelf slide 18 is used to support the shelf 6 that slides out of the self-access opening and guide the shelf 6 to slide in or out.

[0111] Of course, in this embodiment of the invention, the discussion is based on the example of the lower side of the secondary door 12 being hinged to the main door 11. Alternatively, the upper side, left side, or right side of the secondary door 12 can be hinged to the main door 11, so that when the secondary door 12 is flipped outward to the open position, the inner side 101 of the secondary door 12 is above, to the left, or to the right of the retrieval opening 111, and the shelf slide 18 provided on the inner side 101 of the secondary door 12 is located in the front space of the retrieval opening 111. The shelf slide 18 provided on the secondary door 12 can still be used to support and guide the shelf that slides horizontally out or into the retrieval opening 111 (not shown in the accompanying drawings).

[0112] In this embodiment, the washing chamber 3 is provided with multiple shelves 6 arranged vertically. At least the uppermost shelf 61 is opposite to the access opening 111, allowing the uppermost shelf 61 to be removed after the secondary door 12 opens the access opening 111. Alternatively, multiple shelves 6 can be positioned opposite the access opening 111, allowing the secondary door 12 to access and remove multiple shelves 6 located in the upper part of the washing chamber 3 after opening the access opening 111. The following discussion focuses on an example where the washing chamber 3 has two shelves 6, an upper shelf 61 and a lower shelf 62, with the upper shelf 61 accessed and removed through the access opening 111.

[0113] The washing chamber 3 is provided with an upper shelf slide rail 301 that supports the horizontal sliding of the upper shelf 61; such as Figure 15 As shown, when the secondary door 12 is in the open position, the upper shelf slide 301 in the washing chamber 3 is at the same height as the shelf slide 18 on the inner side 101 of the secondary door 12. This guides the upper shelf 61 to slide out of the washing chamber 3 from the retrieval opening 111, guided sequentially by the upper shelf slide 301 and the shelf slide 18. Preferably, the top surfaces of the upper shelf slide 301 and the shelf slide 18 are set to the same horizontal plane or slightly inclined downwards towards the inside of the washing chamber 3, further facilitating the support and guidance of the upper shelf 61 by the cooperation of the two slides set inside and outside the washing chamber 3.

[0114] In this embodiment, the shelf slide 18 provided on the secondary door 12 is a second slide 122. The second slide 122 includes sliding protrusions 1221 located on the left and right sides of the inner side of the secondary door 12. The two sliding protrusions 1221 are connected at the ends of the inner side 101 of the secondary door 12 away from the hinge structure 13 via limiting protrusions 1222, so that the shelf 6 in the washing chamber 3 is supported and guided by the sliding protrusions 1221 and slides smoothly out of the retrieval opening 111, and can facilitate... The limiting protrusion 1222 restricts the shelf 6 that slides out of the washing chamber 3, preventing the shelf 6 from falling off the secondary door 12 after sliding out of the washing chamber 3. In addition, the shelf slide 18 on the secondary door 12 can be used to support the shelf that slides out of the washing chamber 3, allowing the user to take the slid-out shelf 6 upwards. The shelf slide 18 on the secondary door 12 can ensure the guidance and support of the shelf 6 during the sliding process, and also avoid the shelf slide 18 restricting the taking and putting of the slid-out shelf 6.

[0115] In this embodiment, the sliding protrusion 1221 and the limiting protrusion 1222 are integrally formed to constitute the second slide rail 122. Alternatively, the second slide rail 122 can be integrally formed with the secondary door body 12 or fixedly installed. Preferably, the connection points between the sliding protrusions 1221 and the limiting protrusions 1222 on both sides of the second slide rail 122 are provided with arc-shaped transition portions, so that the second slide rail 122 extends in a "U" shape.

[0116] In this embodiment, the sliding protrusion 1221 and the limiting protrusion 1222 are composed of strip-shaped protrusions provided on the inner side surface 101 of the sub-door body 12. The upper side of the strip-shaped protrusion is in the same plane. The lower part of the shelf 6 that slides in and out from the take-up opening 111 can be placed on the upper side surface of the strip-shaped protrusion. A pulley supported on the strip-shaped protrusion can also be provided on the shelf 6. With the above structure, the shelf 6 and the shelf slide 18 can achieve a relative sliding limiting connection.

[0117] In this embodiment, the main door 11 is provided with a pick-up and put-out opening 111 on its upper part; the secondary door 12 covers the pick-up and put-out opening 111 on the upper part of the main door 11; when the secondary door 12 closes the pick-up and put-out opening 111, the outer side 102 of the main door 11 and the secondary door 12 facing away from the washing chamber 3 of the dishwasher are together in the same vertical plane, so that the outer side 102 of the entire door structure 1 of the dishwasher forms a vertical plane, thereby greatly improving the aesthetic appearance of the outer side of the door structure 1 of the dishwasher.

[0118] like Figure 11As shown, in this embodiment, the secondary door 12 is closed on the upper part of the main door 11. The secondary door 12 overlaps with the first main door portion 114 on the upper part of the main door 11. The area where the first main door portion 114 on the upper part of the main door 11 overlaps with the secondary door 12 is the door opening. The door opening has the aforementioned take-up and put-down opening 111. The side of the main door 11 facing away from the washing chamber 3 is the outer side 102. The outer side 102 of the door opening is offset towards the inside of the washing chamber 3 by a set distance relative to the outer side 102 of the other parts of the main door 11. The set distance is equal to the thickness of the remaining parts of the main door 11, so that after the secondary door 12 closes the take-up and put-down opening 111, the outer side 102 of the secondary door 12 and the main door 11 form a vertical surface, thereby effectively improving the overall aesthetics of the dishwasher door structure 1.

[0119] Meanwhile, preferably, in order to further ensure the overall aesthetics of the door structure 1, after the secondary door 12 closes the access opening 111 of the main door 11, the inner side 101 of the main door 11 and the inner side 101 of the secondary door 12 are in the same vertical plane, so that after the door structure 1 is opened outward as a whole, the inner side 101 of the side of the door structure 1 facing the user still forms an overall smooth surface.

[0120] Furthermore, in this embodiment, the inner side 101 of the lower part of the main door 11 is provided with a first slide rail 113 protruding into the washing chamber 3. The first slide rail 113 includes strip-shaped protrusions protruding into the washing chamber 3 on the left and right sides of the inner side 101 of the main door 11. The first slide rail 113 on the main door 11 is connected to the second slide rail 122 on the secondary door 12 so that after the secondary door 12 closes the take-up and take-down opening 111, the second slide rail 122 on the secondary door 12 and the first slide rail 113 on the main door 11 are connected to form a whole slide rail structure. When the main door 11 is flipped open outward, a whole horizontally extending "U"-shaped shelf slide rail 18 is formed on the upper side of the main door 11 to support and guide the lower shelf 62 as it slides out and slides in through the opening 31 of the washing chamber 3.

[0121] In this embodiment, the inner sidewalls of the main door body 11 and the secondary door body 12 are respectively provided with a first slide rail 113 and a second slide rail 122, which are spliced ​​together to form a shelf slide rail 18. Figure 14 and Figure 15 As shown, after the secondary door 12 flips open outwards, the second slide rail 122 extends horizontally to the upper shelf slide rail 301 in the washing chamber 3 or gradually slopes downwards from back to front, serving to guide and support the upper shelf 61 as it slides outwards; simultaneously, as Figure 16As shown, after the main door 11 is flipped open outward, the first slide rail 113 and the second slide rail 122 are both flush with the lower shelf slide rail 302 in the washing chamber 3 or extend downward from back to front, so as to guide and support the lower shelf 62 when it slides outward.

[0122] like Figure 16 As shown, in this embodiment, the first slide rail 113 is disposed opposite to each other on the left and right sides of the inner sidewall of the second main door body 115, and the second slide rail 122 is disposed opposite to each other on the left and right sides of the inner sidewall of the secondary door body 12, corresponding to the first slide rail 113 to form two vertically disposed slide rails; and the tops of the slide rails on the left and right sides of the second slide rail 122 are connected to each other, so that after the secondary door body 12 is opened to the horizontal position, the second slide rail 122 can form a horizontally extending "U" shaped slide rail to guide the upper shelf 61 towards The slide rails 113 and 122 provide guidance and support as the lower shelf 62 slides outward. Simultaneously, after both the secondary and main doors open to a horizontal position, the first slide rail 113 and the second slide rail 122 together form a horizontally extending "U"-shaped slide rail to guide and support the lower shelf 62 as it slides outward. Furthermore, the connecting portions on the left and right sides of the second slide rail 122 can be used to block the sliding upper shelf 61 and lower shelf 62, preventing them from sliding out excessively and causing them to detach from the slide rail. In this embodiment, the second slide rail 122 can extend entirely into the access opening 111, and the second slide rail 122 is in sealed contact with the inner circumference of the access opening 111, achieving a sealing effect at the junction of the secondary and main doors.

[0123] In this embodiment, as shown in the figure above, the upper shelf 61 and the lower shelf 62 can be pulled outwards and supported on the upper shelf slide 301 and the lower shelf slide 302 in the washing chamber 3, respectively. Alternatively, the upper shelf slide 301 and the lower shelf slide 302 can be configured as two parts that can be pulled out horizontally, with one part fixed to the washing chamber 3 and the other part supporting the upper shelf slide 301 and the lower shelf slide 302 respectively. This allows the movable part of the upper or lower shelf slide in the washing chamber 3 to be pulled out along with the upper or lower shelf 6, and the shelf slide 18 provided on the door structure 1 to support the movable part of the slide. This also achieves the effect of using the shelf slide 18 on the door structure 1 to support the pulled-out shelf 6 upwards.

[0124] like Figure 11 and Figure 14As shown, in this embodiment, when the secondary door 12 and the main door 11 are overlapped, the following configuration can be made: the outer periphery of the secondary door 12 is provided with a bent portion 103 extending towards the washing chamber 3. The bent portion 103 covers the outer periphery of the main door 11, so that the bent portion 103 of the secondary door 12 constitutes part of the outer periphery of the entire door structure 1, so that the layered structure cannot be seen when observing the outer periphery of the door structure 1, further improving the aesthetics of the dishwasher door structure 1.

[0125] Preferred, such as Figure 11 As shown, the top of the secondary door 12 is provided with an upper bending portion 1031 that bends horizontally towards the washing chamber 3. The upper bending portion 1031 covers the upper side of the main door 11. The top surface of the upper bending portion 1031 is flush with the top surface of the dishwasher body 2, so that when the dishwasher door structure 1 is closed, the top surface of the door structure 1 is flush with the body 2, so that the user cannot observe the stacked structure of the dishwasher door structure 1 from above, effectively improving the overall aesthetics of the dishwasher door structure 1.

[0126] In addition, side bending portions that bend towards the washing chamber 3 can be provided on the left and right sides of the auxiliary door body 12. The side bending portions cover the corresponding side of the upper part of the main door body 11, and the corresponding side of the lower part of the main door body 11 is flush with the side bending surfaces, so that the user still cannot observe the stacked structure of the dishwasher door structure 1 (not shown in the figure) from both sides.

[0127] like Figure 13 As shown, in this embodiment, when the secondary door 12 and the main door 11 are assembled by embedding, a groove portion recessed towards the interior of the washing chamber 3 can be provided on the upper part of the main door 11, and the retrieval opening 111 is provided at the bottom of the groove portion; the secondary door 12 is correspondingly closed on the upper part of the main door 11, and the secondary door 12 is embedded in the groove portion. The depth of the groove portion is equal to the thickness of the secondary door 12, so that when the secondary door 12 closes the retrieval opening 111, the front side of the secondary door 12 is flush with the front side of the main door 11, forming a vertical plane.

[0128] In this embodiment, to facilitate the opening and closing of the secondary door 12, a handle 123 can be provided on the outer side of the secondary door 12. The handle 123 can be a protrusion or a recess on the outer wall of the secondary door 12, allowing the user to easily insert or grasp the handle 123 to achieve the effect of pulling the secondary door 12 inward and outward, thereby greatly improving the convenience of the user in opening and closing the secondary door 12. At the same time, after the secondary door 12 is closed on the main door 11, the user can also use the handle 123 to open and close the entire door structure 1, so as to achieve the effect of opening or closing the front opening 31 of the washing chamber 3 as a whole.

[0129] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced.
