Description

Technical Field

[0001] The present invention relates to the technical field of dishwashers, and in particular to a dishwasher. Background Art

[0002] Dishwashers have gradually become a common household appliance, used in the kitchen to wash dishes and other tableware after meals, and some models of dishwashers also have functions such as fruit and vegetable washing and seafood washing. However, existing dishwashers do not have a dedicated washing basket to load fruits and vegetables and seafood for washing. Fruits and vegetables or seafood can only be placed on the upper or lower basket, but the gap between the frames on the upper or lower basket is large, and the upper or lower basket cannot support smaller fruits and seafood, which has poor applicability. In addition, when washing live seafood such as crayfish, since the live seafood cannot be restricted from crawling or jumping around, the cleaning effect is affected, and even the spray arm or filter net is damaged. Therefore, it is urgent to develop a dishwasher equipped with a dedicated washing basket and strengthen the effective cleaning of items in the dedicated washing basket. Summary of the invention In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide a dishwasher, aiming to solve the problem of loading and effectively washing fruits, vegetables and seafood.

DETAILED DESCRIPTION

[0024] The present invention provides a dishwasher. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the scope of protection of the present invention.

[0025] See also Figure 1 and Figure 2 The present invention provides a dishwasher, comprising a square housing 1 with a front opening, an upper bowl basket (not shown) and a lower bowl basket 2 which can be pulled forward and backward and arranged in the housing, and a spray structure arranged in the housing, wherein a special washing basket 8 is placed in the rear half area of ​​the lower bowl basket 2, and the spray structure comprises a lower rotating spray arm 3 arranged at the inner bottom of the housing, an upper rotating spray arm 4 arranged at the inner top of the housing, a rear fixed spray arm 6 arranged on the rear end surface of the housing, and a split spray arm 4, a rear fixed spray arm 6 and a lower rotating spray arm 3 which form a waterway connection. The water pipe 5 is provided with a plurality of first washing nozzles 61 for spraying water toward the special cleaning basket 8. The special cleaning basket 8 comprises a rectangular bottom mesh plate 81, two long side mesh plates 82 respectively connected to the long sides of the bottom mesh plate 81, and two short side mesh plates 83 respectively connected to the short sides of the bottom mesh plate 81. The two long side mesh plates 82, the two short mesh plates and the bottom mesh plate 81 form an article cleaning cavity 84. A top mesh cover 85 for intercepting living things from escaping from the article cleaning cavity 84 can be arranged directly above the bottom mesh plate 81.

[0026] After the user puts the fruits, vegetables or seafood to be washed into the special washing basket 8, if the seafood to be washed is live, the top mesh cover 85 is used to cover the washing basket to prevent the live seafood from climbing over and escaping; after the dishwasher is started, the spray structure starts to work, and the water pump pumps the water flow through the water distribution pipe 5 to each spray arm, especially the first washing nozzle 61 of the rear fixed spray arm 6 will directly spray the directional water flow toward the top of the special washing basket 8, directly acting on the items in the special washing basket 8, providing more effective washing force. At the same time, the lower rotating spray arm 3 will rotate and spray water from the bottom of the special washing basket 8 to spray and rinse the items in the basket, reducing the cleaning dead corners, and the upper rotating spray arm 4 will also rotate and spray water to further enhance the cleaning effect.

[0027] Compared with the prior art, the dishwasher provided by the present invention properly loads fruits, vegetables and seafood by providing a special washing basket 8, ensuring that the items in the basket will not fall out of the item washing chamber 84 during the washing process, and optimizes the spray structure, and adds a first washing nozzle 61 of the rear fixed spray arm 6 to directly spray water at the special washing basket 8, and then combines the upper rotating spray arm 4 and the lower rotating spray arm 3 to spray the special washing basket 8, which can more effectively wash small fruits, vegetables and seafood, ensure that every corner in the basket can be covered by the water flow, and the items to be washed in the basket can be washed without dead ends, which can greatly improve the washing rate.

[0028] In this embodiment, see Figure 1 As shown, the plurality of first washing nozzles 61 are arranged in a horizontally spaced arrangement and the heights of two adjacent first washing nozzles 61 are staggered. In this way, the ejected water flow can more evenly cover different areas in the dedicated washing basket 8. Even if a large number of items are placed in the washing basket 8, it can ensure that each item can be touched by the water flow, thereby improving the uniformity and thoroughness of the washing. Moreover, the staggered layout of the first washing nozzles 61 is conducive to generating multi-directional water flow impact, which helps to loosen and remove dirt on the surface of fruits, vegetables or seafood, especially for some uneven surfaces or stains in gaps. This multi-angle water flow impact is more conducive to cleaning.

[0029] Since the water flow sprayed by the upper rotating spray arm 4 may be blocked by the items on the upper bowl basket, the cleaning effect is reduced, and the first washing nozzle 61 may also have a spray limitation problem; therefore, in order to further improve the cleaning effect of the dedicated washing basket 8, see Figure 1 and Figure 2As shown, two symmetrically arranged swing spray arms 7 are provided on the top of the rear fixed spray arm 6, and a plurality of driving nozzles 72 and a second washing nozzle 71 are provided on the bottom surface of each swing spray arm 7. A tension spring 73 for pulling the swing spray arm 7 back to its original position is provided on the rear end surface of the housing. The swing spray arm 7 is connected to the water path of the rear fixed spray arm 6. When the dishwasher is spraying and cleaning, the driving nozzle 72 overcomes the tension of the tension spring 73 through the reaction force of the water spraying, so that the entire swing spray arm 7 is swung forward, so that the swing spray arm 7 is located directly above the special cleaning basket 8, and the second washing nozzle 71 is spraying water downward to the special cleaning basket 8; after cleaning, since the swing spray arm 7 loses the rotational force of the water spraying, the tension spring 73 pulls the swing spray arm 7 to automatically reset to directly above the rear fixed spray arm 6, so as not to interfere with the placement and removal of the special cleaning basket 8.

[0030] The setting of the swing spray arm 7 can further strengthen the impact of the water flow on the items in the special washing basket 8. In particular, for the hard-to-clean parts, the second washing nozzle 71 can provide additional cleaning force to ensure more thorough cleaning. The swing spray arm 7 automatically extends to the top of the special washing basket 8 during the cleaning process and automatically resets after the cleaning is completed. This dynamic positioning mechanism can ensure that the water flow can be accurately sprayed to the target area during the cleaning process, and does not hinder the placement and removal of the special washing basket 8 in the non-cleaning state, thereby improving the convenience of operation.

[0031] In fact, the dishwasher can be set to supply water only in the fruit and vegetable washing and seafood washing modes, so as to ensure that the water supply and spray pressure of the upper rotating spray arm 4 and the lower rotating spray arm 3 are sufficient in the daily dishwashing mode, and the water channel of the water distribution pipe 5 is provided with an electric control valve for controlling the water supply to the rear fixed spray arm 6 and the swinging spray arm 7. In other words, in the non-fruit and vegetable washing and seafood washing modes, the electric control valve closes the water supply of the rear fixed spray arm 6 and the swinging spray arm 7, which can avoid unnecessary water flow dispersion, ensure that the water flow of the upper rotating spray arm 4 and the lower rotating spray arm 3 is concentrated for the washing of conventional tableware, and improve the washing efficiency in the conventional washing mode. In the fruit and vegetable washing and seafood washing modes, the water supply of the rear fixed spray arm 6 and the swinging spray arm 7 is controlled by the electric control valve, which can ensure that the water flow is mainly concentrated at the position of the special washing basket 8 in these modes, thereby optimizing the distribution of water resources, ensuring the washing effect while saving water.

[0032] In fact, fruits can be divided into large fruits and small fruits according to their sizes. If the mesh holes of the bottom grille of the cleaning basket are blindly set to be larger, it will be beneficial to clean large fruits, but small fruits will easily leak out of the mesh holes. If the mesh holes of the bottom grille of the cleaning basket are blindly set to be smaller, the large fruits will be blocked by a larger area and will be difficult to clean.

[0033] See Figure 3 and Figure 4As shown, for this purpose, the bottom of the bottom mesh plate 81 is slidably connected to an adjustable mesh plate 86 that can move laterally. The mesh sizes of the bottom mesh plate 81 and the adjustable mesh plate 86 are the same. The mesh size of the grille at the bottom of the cleaning basket is controlled by the adjustable mesh plate 86 to adapt to the cleaning of different items.

[0034] When washing large fruits or vegetables, the meshes of the bottom mesh plate 81 and the adjustable mesh plate 86 are adjusted to overlap, and a sparsely-perforated grid structure 881 is formed at the bottom of the washing basket. The washing basket does not need to be provided with a top mesh cover 85, and the washing basket is in an upper opening mode.

[0035] When washing small fruits, the meshes of the bottom mesh plate 81 and the adjustable mesh plate 86 are adjusted to be staggered, and a dense grid structure 882 is formed at the bottom of the washing basket. The washing basket does not need to be provided with a top mesh cover 85, and the washing basket is in an upper opening mode.

[0036] When cleaning live seafood, the meshes of the bottom mesh plate 81 and the adjustable mesh plate 86 are adjusted to overlap or stagger according to the size of the live seafood, and then a top mesh cover 85 is set on the top of the cleaning basket to intercept the live seafood from escaping from the item cleaning chamber 84.

[0037] By designing the adjustable mesh plate 86 that can move laterally, the mesh size at the bottom of the washing basket can be adjusted according to the different sizes of fruits and vegetables and seafood, so as to achieve effective cleaning of items of different sizes, prevent small items from falling through the mesh, and also ensure that large items can be fully impacted by the water flow. In addition, the washing basket can be switched between the upper opening mode without a top cover and the closed mode with a top cover, that is, without the obstruction of the top cover, the water flow is more free to shoot from above to the static items in the item washing chamber 84, achieving a better cleaning effect, and the top mesh cover 85 is used to prevent seafood from escaping, avoiding potential damage to other components inside the dishwasher, while also ensuring the safety and effectiveness of the cleaning process.

[0038] For details, see Figure 5 As shown, the bottom of the bottom mesh plate 81 is provided with a flange 811 supporting the adjustable mesh plate 86, and the adjustable mesh plate 86 is provided with a convex strip 861 which is slidably connected to the flange 811 and extends laterally; the convex strip 861 slides relative to the flange 811 in line contact, and this line contact method can significantly reduce the contact area between the two, thereby effectively reducing the friction during the sliding process, making it easier and more convenient for users to adjust the mesh size.

[0039] Furthermore, the upper surface of the adjustable mesh plate 86 is raised to form a handle 862. The design of the handle 862 makes it easier for the user to apply force when adjusting the position of the adjustable mesh plate 86, and the operation is more convenient and quick, especially when the hands are wet or wearing gloves, the mesh size can be easily adjusted. The presence of the handle 862 reduces the necessity of directly contacting the mesh of the adjustable mesh plate 86, avoids the risk of accidental injury caused by fingers accidentally entering the mesh, and improves the safety of use.

[0040] For details, see Figure 6 and Figure 7 As shown, the top mesh cover 85 includes two sub-mesh covers 851 which are rotatably connected to the tops of the corresponding long side mesh plates 82, and the bottom surfaces of the sub-mesh covers 851 are provided with limiting ribs 852 which abut against the inner surfaces of the long side mesh plates 82, so that the two sub-mesh covers 851 can maintain a horizontal state for splicing after being flipped inwards. In other words, the limiting ribs 852 limit the gravity of the sub-mesh covers 851 to further drive the sub-mesh covers 851 to flip; it is not easy to loosen or fall off due to external impact, thereby increasing the stability of the top mesh cover 85.

[0041] By setting in this way, the design of the subnet cover 851 allows the user to open or close the top net cover 85 by a simple flipping action, without disassembling the entire top net cover 85, and the operation is more convenient and quick. When the top net cover 85 is not needed, the two subnet covers 851 can be flipped outward to the periphery of the long side net plate 82, so that more space can be freed up inside the washing basket, which is not only convenient for putting in or taking out larger items, but also without the obstruction of the top cover, the water flow can be shot from above to the static items in the item washing chamber 84 without dead angles, achieving a better washing effect. When washing live seafood, the subnet cover 851 can effectively prevent the seafood from flipping out, protect other components inside the dishwasher from damage, and ensure the washing effect.

[0042] Preferably, see Figure 3 and Figure 7 As shown, a hook 853 is provided in the middle of the subnet cover 851, and a lock hole 821 is provided in the middle of the long side mesh plate 82 to match the hook 853. When the hook 853 is combined with the lock hole 821, the subnet cover 851 hanging to the periphery of the long side mesh plate 82 is restricted from turning over. The matching design of the hook 853 and the lock hole 821 allows the subnet cover 851 to be firmly locked when turning over to the periphery of the long side mesh plate 82, preventing the subnet cover 851 from accidentally turning over due to the jet effect or other external force during the operation of the dishwasher, which affects the cleaning effect or causes safety hazards.

[0043] If the two long side mesh panels 82 and the two short side mesh panels 83 are fixed or integrally formed, the rectangular cleaning basket will take up a lot of space when not in use. Therefore, the present invention provides a foldable and storable cleaning basket. Figure 3As shown, specifically, the lower edges of the two long side mesh panels 82 and the two short side mesh panels 83 are rotatably connected to the bottom mesh panel 81, and the upper surface of the bottom mesh panel 81 is provided with a long limit edge 812 for limiting the excessive outward rotation of the vertical long side mesh panels 82, and the long limit edge 812 limits the long side mesh panels 82 to be able to rotate only within the range of 0°-90° to achieve the switching between the horizontal state and the vertical state; similarly, the upper surface of the bottom mesh panel 81 is provided with a short limit edge 813 for limiting the excessive outward rotation of the vertical short side mesh panels 83, and the short limit edge 813 limits the long side mesh panels 82 to be able to rotate only within the range of 0°-90° to achieve the switching between the horizontal state and the vertical state; in addition, in order to avoid interference between the short side mesh panels 83 and the long side mesh panels 82 when they are stored and folded, the bottom edge height of the short side mesh panels 83 is higher than the bottom edge height of the long side mesh panels 82; see Figure 8 As shown, when storing, first overlap the two long side mesh panels 82 on the bottom mesh panel 81, and then overlap the two short side mesh panels 83 on the long side mesh panels 82, which greatly reduces the space occupied by the cleaning basket and facilitates storage and carrying.

[0044] When the cleaning basket in the storage state is to be converted into the use state, first stand up the two short side mesh panels 83, then stand up the two long side mesh panels 82, and finally connect the long side mesh panels 82 and the short side mesh panels 83 by snapping, so that the user can quickly assemble the cleaning basket without the need for tool-assisted installation, which simplifies the operation process and improves the convenience of use.

[0045] In this embodiment, see Figure 3 and Figure 7 As shown, the short side mesh plate 83 is provided with a limiting vertical plate 832 that abuts against the long side mesh plate 82 and is provided with an elastically deformable pressing lock buckle 831 , and the pressing lock buckle 831 and the limiting vertical plate 832 jointly clamp the side of the long side mesh plate 82 . During assembly, the two short side mesh panels 83 are first erected, and then the two long side mesh panels 82 are flipped and erected. Since the push lock buckle 831 is tilted and protrudes inward from the inner side of the short side mesh panel 83, the long side mesh panel 82 will first contact the root of the push lock buckle 831, and then the long side mesh panel 82 is flipped and the push lock buckle 831 is squeezed and swung outward until the long side mesh panel 82 passes the free end of the push lock buckle 831, and the push lock buckle 831 is reset inward again, and the long side mesh panel 82 is stuck between the push lock buckle 831 and the limit vertical plate 832, which is not only easy to operate, but also effectively fixes the long side mesh panel 82 on the two erected short side mesh panels 83, ensuring the stability of the washing basket when in use, and preventing the side mesh panels from loosening or separating during the washing process. On the contrary, when storing the washing basket, the user manually squeezes the push lock buckle 831 and swings it outward, and then flips the long side mesh panel 82 to a horizontal position.

[0046] In order to further improve the compatibility and practicality of the washing basket, in addition to the function of loading fruits, vegetables and seafood, the washing basket should also take into account the loading capacity of long cups, so as to solve the technical problem that cups such as sports water cups and baby bottles cannot be fixed upright due to their long length and can only be placed horizontally, and the bottom jet of the dishwasher is difficult to clean the inside of sports water cups and baby bottles. Fig. 9 As shown, a plurality of cup holders 87 are rotatably connected to the inner side surface of the long side mesh plate 82, and the cup holder 87 includes a semicircular positioning hoop 871 and a connecting body 872 arranged in the middle of the positioning hoop 871. When the cup holder 87 is in use, the cup holder 87 is flipped to a horizontal state, and the long side mesh plate 82 is provided with a positioning rib 825 at the connection with the connecting body 872, so that the cup holder 87 can maintain a horizontal state, and can well fix the downward long cylindrical cup to prevent it from falling down due to the impact of water flow during the cleaning process, thereby ensuring the stability of the cup during the cleaning process.

[0047] Preferably, the long side mesh plate 82 is provided with a storage slot 823 that is gap-matched with the cup holder 87. The design of the storage slot 823 allows the cup holder 87 to be stored in the long side mesh plate 82 when not in use, thereby reducing the space occupied by the cup holder 87 inside the cleaning basket, so that the cleaning basket can be loaded with more other types of items when the cup holder 87 is not in use.

[0048] It should be noted that the dishwasher is also equipped with a door body for controlling the opening and closing of the front opening of the square housing 1, as well as conventional components such as a water pump, a heating component, a water inlet pipe, and a drain pipe, which are not the focus of the invention and are not described in detail. The working principles of the rotation and spraying of the upper rotating spray arm 4 and the lower rotating spray arm 3 are all prior arts and are not described in detail here.
