Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, specifically to a rotary dish rack layer-washing dishwasher. Background Technology

[0002] In the current dishwasher technology field, the design concepts of rotating racks and layered cleaning have gradually become popular. Traditional dishwashers mostly use a single spray mode, resulting in limited cleaning effectiveness. However, some existing dishwashers have incorporated rotating racks, allowing the dishes to come into contact with water from multiple directions, thus improving cleaning efficiency to some extent. Layered cleaning is also being applied, allowing different spray intensities and modes to be set for different layers based on the type of tableware; for example, the upper layer cleans lighter dishes, while the lower layer focuses on cleaning heavily soiled dishes. The application of these technologies optimizes the cleaning process to a certain extent and meets diverse tableware cleaning needs. However, the following problems exist with existing technologies:

[0003] Existing rotary rack-type dishwashers lack staggered reverse spray components between racks, resulting in a relatively simple spray pattern that can easily leave cleaning blind spots. Since a single spray pattern may require multiple repetitions to achieve a certain cleaning effect, this undoubtedly increases cleaning time and reduces overall cleaning efficiency, failing to meet users' needs for efficient dishwashing. Furthermore, the fixed spacing between racks in existing devices may prevent the washing of certain sized dishes, making the equipment unable to adapt to the diverse dishwashing needs of different households and reducing its versatility.

[0020] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0021] like Figure 1 , Figure 2 As shown, this utility model provides a rotary rack layered washing dishwasher, including a dishwasher shell 10, a sealing door 11 hinged to the front of the dishwasher shell 10, a handle 12 fixedly connected to the front of the sealing door 11, a water outlet pipe 13 fixedly connected to the bottom of the left side wall of the dishwasher shell 10, a solenoid valve 14 fixedly connected to the outer wall of the water outlet pipe 13, a water inlet pipe 15 fixedly connected to the top of the dishwasher shell 10, an interlayer staggered reverse spray assembly 2 is provided inside the dishwasher shell 10, three racks 16 are provided on the outer surface of the interlayer staggered reverse spray assembly 2, and several dish dividers arranged in a ring array are fixedly connected to the inner bottom wall of each of the three racks 16. Ear seats 17 are fixedly connected to the left and right sides of the outer walls of the three racks 16, and a rack spacing adjustment assembly 3 is provided between two adjacent ear seats 17.

[0022] The dishwasher outer shell 10 is made of stainless steel, which has good corrosion resistance and sturdiness. The sealing door 11 is also made of stainless steel, and a handle 12 is welded to the front side to facilitate users to open and close the sealing door 11. A solenoid valve 14 is fixedly connected to the outer wall of the water outlet pipe 13 near the dishwasher outer shell 10 using a pipe clamp. The solenoid valve 14 is model ZCT-15 and is used to control drainage. The function of the water inlet pipe 15 is to supply water to the inside of the dishwasher. The plate divider makes it convenient for users to place plates and other tableware in the dish rack 16.

[0023] like Figure 3 , Figure 4 As shown, the interlayer staggered reverse spray assembly 2 includes a drive chamber 20. The bottom of the drive chamber 20 is fixedly connected to the inner bottom wall of the dishwasher housing 10. A motor 21 is fixedly connected to the right inner wall of the drive chamber 20. A bevel gear 22 is fixedly connected to the output end of the motor 21. A bevel gear 23 is meshed with the bottom of the bevel gear 22. A hollow rotating rod 25, which is rotatably connected to the inner bottom wall of the drive chamber 20, is fixedly connected inside the bevel gear 23. A bevel gear 24 is meshed with the top of the bevel gear 22. The inner wall of the bevel gear 24 is fixedly connected to a hollow rotating outer rod 26 that is rotatably connected to the outer wall of the hollow rotating rod 25. The top of the hollow rotating outer rod 26 extends through to the top of the drive chamber 20 and the outer wall of the hollow rotating outer rod 26 is rotatably connected to the drive chamber 20. The top of the hollow rotating rod 25 passes through the top of the hollow rotating outer rod 26 and the three dish racks 16 in sequence and extends to the inner top wall of the dishwasher housing 10. The bottom of the water inlet pipe 15 extends through to the inside of the dishwasher housing 10 and is rotatably connected to the top of the hollow rotating rod 25.

[0024] like Figure 3 , Figure 4As shown, the bottom basket 16 is fixedly connected to the top of the outer wall of the hollow rotating outer rod 26. The inner walls of the two upper baskets 16 do not contact the outer wall of the hollow rotating rod 25. The outer wall of the hollow rotating rod 25 is fixedly connected to three cross spray frames 27 that are distributed vertically at equal intervals. Several evenly distributed spray holes 28 are opened on the upper and lower sides of the three cross spray frames 27. The cross spray frames 27 are set between two adjacent baskets 16.

[0025] When the dishes need to be washed, motor 21 is started. The output of motor 21 drives bevel gear 22 to rotate via a coupling. The rotation of bevel gear 22 drives bevel gear 23, which meshes with it. The interior of bevel gear 23 is connected to a hollow rotating rod 25 via a key, causing the hollow rotating rod 25 to rotate. At the same time, the rotation of bevel gear 22 also drives bevel gear 24, which meshes with it. The inner wall of bevel gear 24 is connected to a hollow rotating outer rod 26 via a key. The outer wall of the hollow rotating outer rod 26 is rotatably connected to the hollow rotating rod 25 via a deep groove ball bearing, and its top is rotatably connected to the top of the drive chamber 20 via a sealed bearing. This causes the hollow rotating outer rod 26 to also start rotating, but in the opposite direction to the rotation of the hollow rotating rod 25. The top of the hollow rotating rod 25 passes through the top of the hollow rotating outer rod 26 and the three dish baskets 16 in sequence. The water inlet pipe 15 is rotatably connected to the water inlet pipe 15, and the top of the water inlet pipe 15 is connected to an external water source. When water flows through the water inlet pipe 15 into the hollow rotating rod 25, it will spray out from the spray holes 28 on the upper and lower sides of the cross spray rack 27. Since the hollow rotating rod 25 and the hollow rotating outer rod 26 rotate in opposite directions, they drive the cross spray rack 27 and the lower dish rack 16 to rotate in opposite directions, realizing interlayer staggered reverse spraying. Through the set interlayer staggered reverse spraying component 2, the hollow rotating rod 25 and the hollow rotating outer rod 26 drive the cross spray rack 27 and the lower dish rack 16 to rotate in opposite directions, so that the spray water can be sprayed onto the tableware in the dish rack 16 from multiple angles, cleaning the tableware in the dish rack 16 in all directions, effectively avoiding cleaning dead corners. At the same time, since multiple dish racks 16 can be cleaned in all directions at the same time, there is no need to repeatedly clean the same batch of tableware, saving cleaning time and improving the working efficiency of the dishwasher.

[0026] like Figure 5As shown, the bowl spacing adjustment assembly 3 includes a hollow column 30. The bottom of the hollow column 30 is fixedly connected to the top of the ear seat 17. A lifting column 31 is slidably connected to the outer wall of the hollow column 30. A fixing plate 32 is fixedly connected to the top of the inner wall of the lifting column 31. A rotating column 36 is rotatably connected inside the fixing plate 32. A worm gear 35 is fixedly connected to the top of the outer wall of the rotating column 36. A worm 34 is meshed with the right side of the worm gear 35. The worm 34 is rotatably connected to the top of the inner walls on both the front and rear sides of the lifting column 31. A fixing frame 39 is fixedly connected to the top of the rear side wall of the lifting column 31. A second motor 33 is fixedly connected to the rear side wall of the lifting column 31 inside the fixing frame 39. The output end of the second motor 33 passes through the interior of the lifting column 31 and is fixedly connected to the worm 34.

[0027] like Figure 5 As shown, the bottom of the rotating column 36 extends through to the bottom of the fixed plate 32 and is fixedly connected to a screw 37. The outer wall of the screw 37 is threaded with a fixing nut 38, which is fixedly connected to the top of the inner wall of the hollow column 30. The bottom of the screw 37 is fixedly connected to a limit block, and the top of the lifting column 31 is fixedly connected to the bottom of the upper ear seat 17.

[0028] When the spacing between the dish racks 16 needs to be adjusted, motor 2 33 is started. The output end of motor 2 33 drives the worm gear 34 connected to it to rotate through the coupling. The rotation of the worm gear 34 drives the worm wheel 35 connected to it to rotate. The rotation of the worm wheel 35 drives the rotating column 36 fixedly connected to it to rotate inside the fixed plate 32. The rotation of the rotating column 36 drives the screw 37 fixedly connected to it to rotate. Since the fixing nut 38 is fixed, the rotation of the screw 37 will cause the lifting column 31 to rise and fall on the hollow column 30. By raising and lowering the lifting column 31, the spacing between the upper and lower adjacent dish racks 16 can be adjusted to meet the placement needs of tableware of different sizes. Through the set dish rack spacing adjustment component 3, the spacing of the dish racks 16 can be flexibly adjusted according to the actual size of the tableware to meet the cleaning needs of various tableware. No matter how the size of the tableware changes, a good cleaning effect can be achieved by adjusting the spacing, which increases the versatility and practicality of the dishwasher.

[0029] It should be noted that the speed and forward / reverse rotation parameters of motor 2 33 can be preset through the external PLC control panel, so that the bowl basket 16 can be raised and lowered within a predetermined range, and the bowl basket 16 will not collide with the spray hole 28 during the raising and lowering process.

[0030] The working principle of this rotary rack layer-washing dishwasher will be explained in detail below.

[0031] like Figure 1-5As shown, when the dishes need to be washed, motor 21 is started. The output of motor 21 drives bevel gear 22 to rotate via a coupling. The rotation of bevel gear 22 drives bevel gear 23, which meshes with it, to rotate. The interior of bevel gear 23 is connected to hollow rotating rod 25 via a key, thus causing hollow rotating rod 25 to start rotating. At the same time, the rotation of bevel gear 22 also drives bevel gear 24, which meshes with it, to rotate. The inner wall of bevel gear 24 is connected to hollow rotating outer rod 26 via a key. The outer wall of hollow rotating outer rod 26 is rotatably connected to hollow rotating rod 25 via a deep groove ball bearing, and its top is rotatably connected to the top of drive chamber 20 via a sealed bearing. This causes hollow rotating outer rod 26 to also start rotating, but in the opposite direction to hollow rotating rod 25. The top of hollow rotating rod 25 passes through the top of hollow rotating outer rod 26 and three dish baskets 16 in sequence. It is rotatably connected to the water inlet pipe 15, the top of which is connected to an external water source. When water flows through the water inlet pipe 15 into the hollow rotating rod 25, it will spray out from the spray holes 28 on the upper and lower sides of the cross spray rack 27. Since the hollow rotating rod 25 and the hollow rotating outer rod 26 rotate in opposite directions, they drive the cross spray rack 27 and the lower dish rack 16 to rotate in opposite directions, realizing interlayer staggered reverse spraying. Through the set interlayer staggered reverse spraying component 2, the hollow rotating rod 25 and the hollow rotating outer rod 26 drive the cross spray rack 27 and the lower dish rack 16 to rotate in opposite directions, so that the spray water can be sprayed onto the tableware in the dish rack 16 from multiple angles, cleaning the tableware in the dish rack 16 in all directions, effectively avoiding cleaning dead corners. At the same time, since multiple dish racks 16 can be cleaned in all directions at the same time, there is no need to repeatedly clean the same batch of tableware, saving cleaning time and improving the working efficiency of the dishwasher.

[0032] When the spacing between the dish racks 16 needs to be adjusted, motor 2 33 is started. The output end of motor 2 33 drives the worm gear 34 connected to it to rotate through the coupling. The rotation of the worm gear 34 drives the worm wheel 35 connected to it to rotate. The rotation of the worm wheel 35 drives the rotating column 36 fixedly connected to it to rotate inside the fixed plate 32. The rotation of the rotating column 36 drives the screw 37 fixedly connected to it to rotate. Since the fixing nut 38 is fixed, the rotation of the screw 37 will cause the lifting column 31 to rise and fall on the hollow column 30. By raising and lowering the lifting column 31, the spacing between the upper and lower adjacent dish racks 16 can be adjusted to meet the placement needs of tableware of different sizes. Through the set dish rack spacing adjustment component 3, the spacing of the dish racks 16 can be flexibly adjusted according to the actual size of the tableware to meet the cleaning needs of various tableware. No matter how the size of the tableware changes, a good cleaning effect can be achieved by adjusting the spacing, which increases the versatility and practicality of the dishwasher.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
