[0001] This utility model relates to the field of dishwasher technology, and in particular to a dishwasher with an adjustable multi-directional spray arm. Background Technology

[0002] A dishwasher is a modern household appliance designed to clean dishes and cookware mechanically, reducing the burden of manual washing. Its working principles and functions have been described and analyzed in detail in various sources. The basic working principle of a dishwasher is to clean dishes using sprays of hot water and detergent. The hot water, typically between 55 and 75 degrees Celsius, effectively removes grease and food residue, while the detergent provides cleaning power.

[0003] The existing technology has the following problems:

[0004] Existing dishwashers typically use a side-loading method for washing dishes, but this method makes it difficult to clean the inside of the dishwasher. Some dishwashers that load dishes from the top have a fixed spray arm position, making it difficult to achieve the appropriate spray angle. Utility Model Content

[0005] This invention provides a dishwasher with an adjustable multi-directional spray arm to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A multi-directional spray arm adjustable dishwasher includes a housing, a cover rotatably connected to the upper side of the housing near the rear side, a cleaning mechanism rotatably connected to the middle of the inner side of the housing, a placement rack movably sleeved on the inner side of the cleaning mechanism, and a base movably sleeved on the outer side of the housing near the bottom, with four diamond-shaped fixing mechanisms fixedly connected to the outer side of the base.

[0008] The cleaning mechanism includes a rotating frame, the outer side of which is rotatably connected to the middle of the inner side of the mechanism housing. Several annularly distributed lateral cleaning arms are rotatably connected to the lower side of the rotating frame. Guide plates are fixedly connected to the upper side of the sides of the several lateral cleaning arms that are far apart from each other. Guide rings are movably sleeved on the inner side of the guide plates. Several annularly distributed pushing components are fixedly connected to the upper side of the inner wall of the mechanism housing.

[0009] Preferably, the pushing component includes a first limiting rod, the lower side of which is fixedly connected to the lower inner surface of the inner vertical groove of the mechanism housing, a pushing seat is movably sleeved on the outer side of the first limiting rod, and the outer side of the guide ring is located below the pushing seat. A first spring is movably sleeved on the outer side of the first limiting rod, and the first spring is located below the pushing seat. A telescopic rod is fixedly connected to the upper inner surface of the cover near the edge, and the lower side of the telescopic rod overlaps the upper side of the pushing seat.

[0010] Preferably, the lower side of the pusher seat is rotatably connected with a plurality of evenly distributed ball bearings.

[0011] Preferably, the fixing mechanism includes a mechanism plate, which is fixedly connected to the outer middle of the base on the side near the placement frame. A movable plate is movably sleeved on the inner side of the mechanism plate, and a locking platform is rotatably connected to the upper side of the movable plate. A plurality of linearly distributed second limiting rods are movably sleeved on the inner side of the movable plate, and a second spring is movably sleeved on the outer side of each of the plurality of second limiting rods, with the second spring located on the inner side of the movable plate.

[0012] Preferably, a sliding plate is slidably connected to the lower side of the mechanism plate, and a plurality of linearly distributed locking teeth are movably sleeved on the inner side of the sliding plate. A third spring is movably installed on the side of each locking tooth away from the placement frame. A plurality of linearly distributed locking grooves are opened on the outer side of each of the plurality of second limiting rods, and the outer side of the locking teeth is movably sleeved on the inner side of the locking grooves.

[0013] Preferably, a third limiting rod is fixedly connected to the middle of the side of the sliding plate away from the base, and the bottom of the side of the mechanism plate away from the base is movably sleeved on the outside of the third limiting rod through a circular plate. A fourth spring is movably sleeved on the outside of the third limiting rod, and the fourth spring is located on one side of the circular plate.

[0014] Preferably, the outer side of the card holder near the upper side is a right-angled trapezoid, and the inclined surface of the card holder faces downward.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a multi-directional spray arm adjustable dishwasher, which adopts the cooperation of a base, a housing, a cleaning mechanism, a rotating frame, side cleaning arms, a guide plate, a guide ring, a pushing component, a first limiting rod, a pushing seat, a first spring, a telescopic rod, and a placement rack. The rotating frame drives multiple side cleaning arms to reciprocate, thereby cleaning the dishes on the placement rack. The guide ring moves up and down, thereby adjusting the angle between the side cleaning arms and the outer side of the placement rack. This allows for oblique water spraying when there are deep dishes inside the placement rack, achieving a better cleaning effect. It also adopts a vertical placement form, and the detachable design between the housing and the base facilitates the cleaning of any residue that may remain inside the dishwasher after washing.

[0017] 2. This utility model provides a multi-directional spray arm adjustable dishwasher, which adopts the cooperation of a mechanism shell, base, fixing mechanism, mechanism plate, movable plate, locking platform, second limiting rod, second spring, sliding plate, locking teeth, third spring, locking groove, third limiting rod and fourth spring. By hanging the locking platform on the outer side of the mechanism shell near the bottom flange, and then directly pulling down the second limiting rod, the mechanism shell and the base are quickly fixed together. Pushing the sliding plate allows the mechanism shell and the base to be quickly separated, thus making the disassembly and installation between the mechanism shell and the base more convenient. It avoids the problem of large thickness caused by the existing buckle method, and also avoids the problem of excessive pulling force caused by the buckle method, which requires multiple buckles to avoid poor sealing.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-6 As shown, a multi-directional spray arm adjustable dishwasher includes a housing 1, a cover 2 is rotatably connected to the upper side of the housing 1 near the rear side, a cleaning mechanism 3 is rotatably connected to the middle of the inner side of the housing 1, a placement rack 4 is movably sleeved on the inner side of the cleaning mechanism 3, a base 5 is movably sleeved on the outer side of the housing 1 near the bottom, and four diamond-shaped fixing mechanisms 6 are fixedly connected to the outer side of the base 5.

[0027] The cleaning mechanism 3 includes a rotating frame 31. The outer side of the rotating frame 31 is rotatably connected to the middle of the inner side of the mechanism housing 1. Several annularly distributed lateral cleaning arms 32 are rotatably connected to the lower side of the rotating frame 31. Guide plates 33 are fixedly connected to the upper side of the side of the several lateral cleaning arms 32 that are far apart from each other. Guide rings 34 are movably sleeved on the inner side of the guide plates 33. Several annularly distributed pushing components 35 are fixedly connected to the upper side of the inner wall of the mechanism housing 1.

[0028] It should be noted that a torsion spring is provided between the side cleaning arm 32 and the rotating frame 31 to keep the side cleaning arm 32 in a vertical state. The guide plate 33 is provided with an inclined groove, and the guide ring 34 is located in the inclined groove. When the guide ring 34 moves down, the upper ends of the side cleaning arms 32 move closer to each other. The mechanism housing 1 is provided with a component for driving the rotating frame 31 to reciprocate, so that the rotating frame 31 drives the side cleaning arm 32 to reciprocate.

[0029] like Figure 4As shown, the pushing component 35 includes a first limiting rod 351. The lower side of the first limiting rod 351 is fixedly connected to the lower surface of the inner vertical groove of the outer shell 1. The outer side of the first limiting rod 351 is movably sleeved with a pushing seat 352, and the outer side of the guide ring 34 is located below the pushing seat 352. The outer side of the first limiting rod 351 is movably sleeved with a first spring 353, and the first spring 353 is located below the pushing seat 352. A telescopic rod 354 is fixedly connected to the upper surface of the inner side of the cover 2 near the edge, and the lower side of the telescopic rod 354 overlaps the upper side of the pushing seat 352.

[0030] It should be noted that the telescopic rod 354 controls its own length, causing the telescopic rod 354 to push the push seat 352 downward. When the push seat 352 moves downward, it pushes the guide ring 34 downward. When the length of the telescopic rod 354 is shortened, the first spring 353 pushes the push seat 352 to return to its original position.

[0031] like Figure 4 As shown, a number of evenly distributed balls are rotatably connected to the lower side of the pusher seat 352.

[0032] It should be noted that the guide ring 34 and the guide plate 33 cannot rotate relative to each other, and thus cannot move up and down relative to each other. This causes the guide ring 34 to rotate when the rotating frame 31 rotates. The ball bearings are used to reduce the friction between the push seat 352 and the guide ring 34.

[0033] like Figure 6 As shown, the fixing mechanism 6 includes a mechanism plate 61. The side of the mechanism plate 61 closest to the placement frame 4 is fixedly connected to the outer middle of the base 5. A movable plate 62 is movably sleeved on the inner side of the mechanism plate 61. A locking table 63 is rotatably connected to the upper side of the movable plate 62. Several linearly distributed second limiting rods 64 are movably sleeved on the inner side of the movable plate 62. A second spring 65 is movably sleeved on the outer side of each of the several second limiting rods 64, and the second spring 65 is located on the inner side of the movable plate 62.

[0034] It should be noted that the second spring 65 pushes the inner lower surface of the movable plate 62, causing the movable plate 62 to pull down the locking platform 63. The upper half of the locking platform 63 pulls down the outer flange of the mechanism housing 1 near the bottom, causing the mechanism housing 1 to be fixed on the base 5.

[0035] like Figure 6 As shown, a sliding plate 66 is slidably connected to the lower side of the mechanism plate 61. Several linearly distributed locking teeth 67 are movably sleeved on the inner side of the sliding plate 66. A third spring 68 is movably installed on the side of the locking teeth 67 away from the placement frame 4. Several linearly distributed slots 69 are opened on the outer side of the several second limiting rods 64. The outer side of the locking teeth 67 is movably sleeved on the inner side of the slots 69.

[0036] It should be noted that all the second limit rods 64 are connected by a crossbar. Pulling down the second limit rod 64 causes the locking tooth 67 to limit the second limit rod 64, thereby adjusting the initial compression of the second spring 65, and thus controlling the pressure of the locking table 63 on the outer flange of the mechanism housing 1, making the fixation between the mechanism housing 1 and the base 5 more stable.

[0037] like Figure 5 As shown, a third limiting rod 610 is fixedly connected to the middle of the side of the sliding plate 66 away from the base 5. The bottom of the side of the mechanism plate 61 away from the base 5 is movably sleeved on the outside of the third limiting rod 610 through a circular plate. A fourth spring 611 is movably sleeved on the outside of the third limiting rod 610, and the fourth spring 611 is located on one side of the circular plate.

[0038] It should be noted that pushing the sliding plate 66 causes the locking tooth 67 to disengage from the inside of the slot 69, which allows the second limiting rod 64 to move upward and reset, making the mechanism housing 1 and the base 5 detachable.

[0039] like Figure 5 As shown, the outer side of the card platform 63 near the top is a right trapezoid, and the inclined surface of the card platform 63 faces downward.

[0040] It should be noted that the shape of the card plate 63 allows the card plate 63 to be automatically pulled out of the inner side of the mechanism plate 61 and then rotated outward when the mechanism shell 1 and the base 5 are separated.

[0041] The working principle of this utility model is as follows: First, a torsion spring is provided between the lateral cleaning arm 32 and the rotating frame 31 to keep the lateral cleaning arm 32 in a vertical state. A groove is provided on the guide plate 33, and the guide ring 34 is located within the groove. When the guide ring 34 moves downward, the upper ends of the lateral cleaning arms 32 move closer together. A component is provided inside the outer shell 1 to drive the rotating frame 31 to reciprocate, causing the rotating frame 31 to drive the lateral cleaning arms 32 to reciprocate. The telescopic rod 354 controls its own length, causing the telescopic rod 354 to push the push seat 352 downward. When the push seat 352 moves downward, it pushes the guide ring 34 downward. When the length of the telescopic rod 354... When the length is shortened, the first spring 353 pushes the push seat 352 to return to its original position. This, in turn, drives the multiple lateral cleaning arms 32 to reciprocate through the rotating frame 31, thus cleaning the dishes on the rack 4. The guide ring 34 moves up and down, adjusting the angle between the lateral cleaning arms 32 and the outer side of the rack 4. This allows for a more efficient water spray when there are deep dishes inside the rack 4, achieving a better cleaning effect. The vertical placement and detachable design between the outer casing 1 and the base 5 facilitate the cleaning of any residue inside the dishwasher after washing. Finally, the second spring 65 pushes... The lower inner surface of the movable plate 62 causes the movable plate 62 to pull down the locking platform 63. The upper half of the locking platform 63 pulls down the outer flange of the mechanism housing 1 near the bottom, causing the mechanism housing 1 to be fixed on the base 5. All the second limiting rods 64 are connected by a crossbar. Pulling down the second limiting rod 64 causes the locking tooth 67 to limit the second limiting rod 64, thereby adjusting the initial compression of the second spring 65, and thus controlling the pressure of the locking platform 63 on the outer flange of the mechanism housing 1, making the fixation between the mechanism housing 1 and the base 5 more stable. Pushing the sliding plate 66 causes the locking tooth 67 to disengage from the inner side of the locking groove 69, causing the second limiting rod 64 to be fixed on the base 5. The positioning rod 64 can be moved upwards to reset, allowing the outer shell 1 and the base 5 to be disassembled. By hanging the locking plate 63 on the outer side of the outer shell 1 near the bottom flange, and then pulling down the second limiting rod 64, the outer shell 1 and the base 5 are quickly fixed together. Pushing the sliding plate 66 allows the outer shell 1 and the base 5 to be quickly separated, making the disassembly and installation of the outer shell 1 and the base 5 more convenient. This avoids the problem of excessive thickness caused by using the existing buckle method, and also avoids the problem of excessively concentrated downward force caused by the buckle method, which requires multiple buckles to avoid poor sealing.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
