Description

Technical Field

[0001] This invention belongs to the field of cleaning equipment technology, and specifically relates to a dishwasher. Background Technology

[0002] A dishwasher is a device that sprays cold or hot water onto dishes and other tableware to remove dirt and grime, and washes them. It typically includes an inner tub, a dish rack, and a door. The dish rack slides in and out of the inner tub for easy loading and unloading of dishes. The door and dish rack operate independently. To use it, first open the door, then pull the dish rack out of the inner tub and load the dishes. Once loaded, push the dish rack back into the inner tub, and finally close the door. This entire process is rather cumbersome, and when the dish rack is heavy and has a lot of dishes, it becomes inconvenient to push and pull it, affecting the user experience.

[0003] To address this, Chinese utility model patent application number 201922189774.4, entitled "A Dishwasher" (publication number CN211749441U), discloses a dishwasher. This dishwasher includes a main body with a door rotatably mounted thereon; and a dish rack disposed on the main body and connected to a drive device. The dish rack has a first position extending out of the main body and a second position retracted into the main body under the drive device. This design allows the user to move the dish rack in and out of the dishwasher via the drive device, eliminating the need for manual pushing or pulling of the rack, thus simplifying user operation.

[0004] The above patents do not require users to manually push or pull the dish rack, but they do require an additional drive device to move the dish rack in and out of the dishwasher. Meanwhile, the door and dish rack still operate independently. To address this, Chinese utility model patent application number 202420907914.5, entitled "A Dishwasher" (publication number CN222656979U), discloses a dishwasher including a cabinet with an open front; a door that can rotate relative to the cabinet to open or close; a dish rack that can move back and forth within the cabinet, with at least two rollers spaced apart along its side wall in the front-to-back direction; a fixing block located on the wall of the door facing the cabinet, positioned in front of and above the dish rack when the door is closed; and a pull cord with a closed structure, which passes sequentially around the rollers and the fixing block, and can slide around the fixing block and rollers. This patent uses a pull rope and a fixing block as a transmission mechanism to achieve coordinated work between the door and the dish basket. It enables the dish basket to be pulled out or pushed back simultaneously while the door is opening and closing, simplifying the operation steps and making it convenient to use.

[0005] However, when users close the door, they need to bend over and rotate the door 90 degrees upwards to close it. This bending-over action is not user-friendly for some groups, such as the elderly and pregnant women.

[0006] Meanwhile, in the existing technology, as the bowl basket is pulled out or pushed back into the inner liner when the door is opened and closed, due to inertia, the bowl basket will move relative to the inner liner at a certain speed, and then stop moving after hitting the inner liner. The abnormal noise generated by the impact will affect the user experience, and the impact force generated by the impact will be transmitted to the tableware in the bowl basket, causing the tableware to vibrate or even break. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a dishwasher that can achieve the same coordinated operation of the door and the dish rack, while also avoiding the need for the user to bend over to operate it, in light of the current state of the technology.

[0008] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a dishwasher, comprising: Inner liner, open at the front; The door can be tilted back and forth relative to the inner liner, thereby opening or closing the front opening of the inner liner; A bowl basket that can move back and forth has an extended state where at least part of it extends out of the inner liner through the front opening and a folded state where it moves back into the inner liner. Its characteristic is that it also includes: A transmission mechanism is provided on the side of the inner liner, with the first transmission end of the transmission mechanism connected to the basket and the second transmission end connected to the door. When the door is opened, the transmission mechanism is arranged to convert the forward deflection force of the door into the basket moving forward to the extended state, and when the basket moves backward to the closed state, the transmission mechanism is arranged to convert the backward movement force of the basket into the door deflecting backward to close the door.

[0009] Therefore, when opening the door, simply tilting the door forward will simultaneously move the dish basket forward to its extended position. When closing the door, push the dish basket backward, and the dish basket will tilt the door backward to close it. During this process, the user does not need to bend over to close the door, thus improving the user experience.

[0010] Preferably, the pivot of the door extends to the left and right, and is relatively close to the lower edge of the door and relatively far from the upper edge of the door. That is, the door can be rotated up and down around the pivot to open and close the door.

[0011] Preferably, the inner liner has a slider on its side wall that can move back and forth, and the first transmission end of the transmission mechanism is connected to the bowl basket through the slider.

[0012] Furthermore, the transmission mechanism includes: The joystick is connected to the door and can rotate with the door. The gear set has a first gear and a second gear. The first gear and the second gear mesh with each other and are rotatably connected to the side wall of the inner liner around their respective central axes. The gear ring on the first gear meshes with the teeth on the rocker arm to achieve linkage. The connecting rod has its first end constrained to the slider and its second end constrained to the second gear, so that the second gear is linked with the slider.

[0013] Furthermore, the first end of the connecting rod is provided with a first strip-shaped hole extending along the length direction of the connecting rod, and the slider is provided with a first pin that is inserted into the first strip-shaped hole and can move along the first strip-shaped hole; The second end of the connecting rod is provided with a second strip-shaped hole extending along the length direction of the connecting rod. The second gear is provided with a second pin that is inserted into the second strip-shaped hole and can move along the second strip-shaped hole. The second pin is offset from the central axis of the second gear.

[0014] Furthermore, the diameter of the second gear is smaller than the diameter of the first gear.

[0015] In the above scheme, the transmission mechanism can be located inside the inner liner or outside the inner liner. To avoid the transmission mechanism occupying extra space inside the inner liner, it is preferable that the transmission mechanism is located outside the inner liner. The inner liner has mounting holes extending forward and backward on its side wall; It also includes a conveyor belt that extends forward and backward, erected at the mounting hole to close the mounting hole, and the conveyor belt is connected to the slider and can move together with the slider.

[0016] The conveyor belt design prevents water from spraying out of the mounting holes when the dishwasher is working, and the conveyor belt is connected to the slider so as not to affect the slider's forward and backward movement.

[0017] Furthermore, it also includes a first drive shaft and a second drive shaft extending vertically, which are arranged one in front of the other on both sides of the mounting hole; The conveyor belt is connected end to end and is wrapped around the outer circumference of the first drive shaft and the second drive shaft as a whole, so that the conveyor belt as a whole can rotate clockwise or counterclockwise around the first drive shaft and the second drive shaft. The slider is connected to the conveyor belt.

[0018] This allows the conveyor belt to always cover the mounting holes while also moving with the slider.

[0019] Preferably, the side circumferential surface of the first drive shaft has a toothed ring that meshes with the conveyor belt, and the upper end of the first drive shaft is threadedly connected to the upper threaded hole of the mounting base, and the lower end of the first drive shaft is threadedly connected to the lower threaded hole of the mounting base. When the conveyor belt rotates clockwise or counterclockwise as a whole, the first drive shaft can rotate clockwise or counterclockwise around its own central axis, and can also move up and down relative to the mounting base. Meanwhile, the mounting base is provided with a first damping element for reducing the upward movement speed of the first drive shaft relative to the mounting base, and a second damping element for reducing the downward movement speed of the first drive shaft relative to the mounting base.

[0020] The cooperation between the first and second damping components and the first drive shaft can slow down the rotation speed of the door opening and closing, prevent the bowl rack from moving too fast, and improve safety.

[0021] More preferably, the mounting base has an upper fin positioned below the upper threaded hole as the first damping element, and a lower fin positioned above the lower threaded hole as the second damping element. There are at least two upper fins arranged circumferentially to form an upper channel through which the first drive shaft passes. The upper channel has a structure with a small upper diameter and a large lower diameter. There are at least two lower fins arranged circumferentially to form a lower channel through which the first drive shaft passes. The lower channel has a structure with a large upper diameter and a small lower diameter.

[0022] Meanwhile, the upper side surface of the first drive shaft has an upper step. When the upper step passes through the lower part of the upper channel and enters the upper part of the upper channel, the upper part of the upper channel can squeeze the upper step and slow down the upward movement speed of the first drive shaft relative to the mounting seat. The lower side surface of the first drive shaft has a lower step. When the lower step passes through the upper part of the lower channel and enters the lower part of the lower channel, the lower part of the lower channel can squeeze the lower step and slow down the downward movement speed of the first drive shaft relative to the mounting seat.

[0023] When the upper step enters the upper part of the upper channel, or the lower step enters the lower part of the lower channel, the basket moves forward to a position close to its extended state or backward to a position close to its retracted state. At this time, the cooperation between the first drive shaft and the upper or lower fins can slow down the movement speed of the basket (i.e., slow down the movement speed of the basket when it reaches the extended or retracted state, while the movement speed in the intermediate state between the extended and retracted states is unaffected), preventing the basket from moving too fast. Therefore, this invention, through the design of the conveyor belt for blocking water, the drive shaft that cooperates with the conveyor belt, and the fins, can achieve both water blocking and damping effects, improving safety in use, and the overall structure is simple.

[0024] Compared with the prior art, the advantages of the present invention are as follows: through the design of the transmission mechanism, when opening the door, the door body is tilted forward, which simultaneously moves the dish basket forward to the extended state. When it is necessary to close the door, the dish basket is pushed backward, and the dish basket can tilt the door body backward to close the door. During this process, the user does not need to bend over to close the door, thus improving the user experience. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figures 1-9 As shown, this is a preferred embodiment of a dishwasher according to the present invention. The dishwasher includes an inner tub 1, a door 2, a dish rack 3, a transmission mechanism 4, a conveyor belt 5, a mounting base 6, and a spray mechanism.

[0028] The inner liner 1 is open at the front, and the left and right side walls are provided with mounting holes 10 that extend forward and backward.

[0029] The door 2 can be deflected back and forth relative to the inner liner 1 around a pivot that extends left and right, thereby opening or closing the front opening of the inner liner 1. The pivot is relatively close to the lower edge of the door 2 and relatively far from the upper edge of the door 2.

[0030] The bowl basket 3, used to hold bowls, chopsticks and other tableware, can move back and forth, and has an extended state in which at least the front part extends out of the inner liner 1 through the front opening, and a closed state in which it moves backward into the inner liner 1.

[0031] The spraying mechanism is existing technology and is used to spray water into the inner liner 1 in the direction of the dish basket to clean the tableware in the dish basket.

[0032] There are two sets of transmission mechanisms 4, one on the left and one on the right outside the inner liner 1. The first transmission end of each transmission mechanism 4 is connected to the basket 3 via a corresponding sliding block 11 that can move back and forth (the sliding block 11 is set with mounting holes 10 on the side wall of the inner liner 1 to connect the basket 3 inside and outside the inner liner and the first transmission end of the transmission mechanism 4). The second transmission end is connected to the door 2. When the door is opened, as... Figure 7 , 8As shown, the transmission mechanism 4 is arranged to convert the forward deflection force of the door 2 into the basket 3 moving forward to the extended state, and as... Figures 1-3 As shown, when the basket 3 moves backward to the closed state, the transmission mechanism 4 is arranged to convert the backward movement force of the basket 3 into the backward deflection of the door 2 to close the door. Specifically, the transmission mechanism 4 includes a rocker arm 41, a gear set, and a connecting rod 44. The rocker arm 41 is located at the lower edge of the door 2, connected to the door 2, and can rotate with the door 2. The gear set has a first gear 42, a third gear 45, a fourth gear 46, and a second gear 43 that mesh sequentially. The first gear 42, the third gear 45, the fourth gear 46, and the second gear 43 are rotatably connected to the side wall of the inner liner 1 around their respective left and right extending central axes; the diameters of the first, third, and fourth gears are larger than the diameter of the second gear 43. The gear ring on the first gear 42 meshes with the teeth on the rocker arm 41 to achieve linkage. The first end of the connecting rod 44 is constrained to the slider 11, and the second end of the connecting rod 44 is constrained to the second gear 43, so that the second gear 43 is linked with the slider 11. Specifically, the first end of the connecting rod 44 is provided with a first strip hole 441 extending along the length direction of the connecting rod 44, and the slider 11 is provided with a first pin 111 inserted into the first strip hole 441 and movable along the first strip hole 441; the second end of the connecting rod 44 is provided with a second strip hole 442 extending along the length direction of the connecting rod 44, and the second gear 43 is provided with a second pin 431 inserted into the second strip hole 442 and movable along the second strip hole 442, and the second pin 431 is offset from the central axis of the second gear 43.

[0033] In this embodiment, mounting seats 6 are provided on the outer wall surfaces of the left and right sidewalls of the inner liner 1 at positions corresponding to the mounting holes 10. Each mounting seat 6 has a through-hole 60 extending horizontally and vertically, with the edges of the through-hole 60 recessed to form grooves 601 extending along the edges of the through-hole 60. Figure 6 As shown. Meanwhile, as Figure 2 , 3 As shown, a first drive shaft 51 and a second drive shaft 52 extending vertically are respectively provided in the mounting base 6 at the positions corresponding to the front and rear sides of the through hole 60 (the first drive shaft 51 and the second drive shaft 52 are also located on the front and rear sides of the mounting hole 10). The aforementioned conveyor belt 5 is erected in the through hole 60 at the position corresponding to the mounting hole 10 to close the mounting hole 10. The conveyor belt 5 is connected end to end and is wrapped around the outer periphery of the first drive shaft 51 and the second drive shaft 52 as a whole, so that the conveyor belt 5 can rotate clockwise or counterclockwise around the first drive shaft 51 and the second drive shaft 52. At the same time, the upper and lower edges of the conveyor belt 5 are respectively inserted into the aforementioned groove 601, and the projection of the conveyor belt 5 on the inner liner sidewall completely covers the mounting hole 10, so as to effectively block water.

[0034] Simultaneously, the conveyor belt 5 is connected to the slider 11 and can move together with the slider 11. For example, when the slider 11 moves forward, the conveyor belt 5 rotates clockwise; when the slider 11 moves backward, the conveyor belt 5 rotates counterclockwise. In this embodiment, as shown... Figure 2 , 8 As shown in Figure 9, the connection structure between the conveyor belt 5 and the slider 11 is as follows: the slider 11 has a through hole 112 extending forward and backward for the conveyor belt 5 to pass through. For the conveyor belt 5 located on the left side of the inner liner, the left side of the conveyor belt 5 is connected to the slider 11 by a buckle 53, so that when the slider 11 moves forward, it can move the left side of the conveyor belt 5 forward together, thereby causing the entire conveyor belt to rotate clockwise around the first drive shaft and the second drive shaft (at this time, the right side of the conveyor belt 5 moves backward); when the slider 11 moves backward, it can move the left side of the conveyor belt 5 backward together, thereby causing the entire conveyor belt to rotate counterclockwise around the first drive shaft and the second drive shaft (at this time, the right side of the conveyor belt 5 moves forward). Similarly, for the conveyor belt 5 located on the right side of the inner liner, the right side of the conveyor belt 5 is connected to the slider 11 by a buckle 53. The buckle connection structure is as follows: the conveyor belt 5 has a locking hole 54, and the buckle 53 passes through the locking hole 54 and connects to the slider 11.

[0035] Meanwhile, in this embodiment, as Figures 3-5As shown, the side circumferential surface of the first drive shaft 51 has a toothed ring that meshes with the conveyor belt 5, and the upper end of the first drive shaft 51 is threaded into the upper threaded hole 61 of the mounting base 6, and the lower end of the first drive shaft 51 is threaded into the lower threaded hole 62 of the mounting base 6. When the conveyor belt 5 rotates clockwise or counterclockwise as a whole, the first drive shaft 51 can rotate clockwise or counterclockwise around its own central axis, and can also move up and down relative to the mounting base 6. The mounting base 6 is provided with a first damping element for slowing down the upward movement speed of the first drive shaft 51 relative to the mounting base 6, and a second damping element for slowing down the downward movement speed of the first drive shaft 51 relative to the mounting base 6. Specifically, the mounting base 6 has an upper fin 63 positioned below the upper threaded hole 61 as the first damping element, and a lower fin 64 positioned above the lower threaded hole 62 as the second damping element. There are at least two upper fins 63 arranged circumferentially to form an upper channel 630 through which the first drive shaft 51 passes. The upper channel 630 has a smaller upper diameter and a larger lower diameter. Similarly, there are at least two lower fins 64 arranged circumferentially to form a lower channel 640 through which the first drive shaft 51 passes. The lower channel 640 has a larger upper diameter and a smaller lower diameter. The structure includes: an upper step 511 on the upper side surface of the first drive shaft 51; when the upper step 511 passes through the lower part of the upper channel 630 and enters the upper part of the upper channel 630, the upper part of the upper channel 630 can compress the upper step 511, thus slowing down the upward movement speed of the first drive shaft 51 relative to the mounting base 6; and a lower step 512 on the lower side surface of the first drive shaft 51; when the lower step 512 passes through the upper part of the lower channel 640 and enters the lower part of the lower channel 640, the lower part of the lower channel 640 can compress the lower step 512, thus slowing down the downward movement speed of the first drive shaft 51 relative to the mounting base 6. Simultaneously, when the upper step 511 passes through the lower part of the upper channel 630 and enters the upper part of the upper channel 630, the lower step 512 disengages from the lower part of the lower channel 640; and when the lower step 512 passes through the upper part of the lower channel 640 and enters the lower part of the lower channel 640, the upper step 511 disengages from the upper part of the upper channel 630.

[0036] When the upper step 511 enters the upper part of the upper channel 630, or the lower step 512 enters the lower part of the lower channel 640, the basket moves forward to a position close to the extended state or backward to a position close to the retracted state. At this time, the cooperation between the first drive shaft and the upper or lower fin can slow down the movement speed of the basket (i.e., slow down the movement speed of the basket when it reaches the extended or retracted state, while the movement speed in the intermediate state between the extended and retracted states is unaffected), preventing the basket from moving too fast. Therefore, this invention, through the design of the water-blocking conveyor belt, the drive shaft cooperating with the conveyor belt, and the fins, can achieve both water blocking and damping effects, improving safety in use, and the overall structure is simple.

[0037] The dishwasher of the present invention can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the spray mechanism and other components to perform corresponding operations, thereby realizing intelligent control of the dishwasher and improving the user experience.

[0038] The specification and claims of this invention use terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," to describe various exemplary structural parts and elements of the invention. However, these terms are used herein merely for ease of explanation and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this invention can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be considered as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0039] The term "vertical" is also used in the specification and claims of this invention, meaning basically along the up and down direction, and is not limited to just the vertical direction, but can also be slightly deviated from the vertical direction.
