Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a dispenser and a dishwasher. Background Technology

[0002] A dishwasher is a common kitchen appliance that cleans dishes through automated washing programs. The dispenser, an important functional component of the dishwasher, plays a crucial role in automatically and precisely releasing predetermined doses of different types of detergent, such as detergent and rinse aid, during specific stages of the washing program, thereby achieving efficient and thorough cleaning.

[0003] Currently, most dispensers on the market employ a dual-chamber structure, typically with two separate chambers for detergent and rinse aid, driven by a single solenoid valve. This valve's operation simultaneously opens both chambers. In this configuration, detergent can be added manually when needed, requiring the user to manually open the detergent chamber. However, while the detergent chamber is manually opened, the rinse aid chamber must remain tightly sealed. Because the opening of both chambers is mechanically coupled through the same drive source, manually opening the target chamber can easily and accidentally trigger the other chamber, which should be closed, leading to unintended opening and leakage, thus wasting detergent. Utility Model Content

[0004] Therefore, it is necessary to provide a distributor that can solve the above problems.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] A dispenser comprising:

[0007] The box has a first chamber and a second chamber that are independently arranged.

[0008] A sliding cover is slidably connected to the housing and is used to open / close the first chamber. A manual switch is movably connected to the sliding cover.

[0009] The sliding cover control assembly includes a rotating rod and a transmission plate. The rotating rod is rotatably mounted on the housing and can engage with the sliding cover to control the locking / unlocking of the sliding cover. Furthermore, the end of the rotating rod facing the sliding cover can also abut against the manual switch, and the end of the rotating rod away from the sliding cover is connected to the transmission plate.

[0010] A sealing element for controlling the opening / closing of the second chamber;

[0011] The drive assembly includes a telescopic drive member and a sliding frame. The telescopic rod of the telescopic drive member extends into the sliding frame in a first direction and abuts against and limits the transmission plate. The sliding frame is slidably connected to the housing and the sealing member in the first direction, and the sliding frame can simultaneously drive the sealing member and the transmission plate to move.

[0012] When the manual switch pushes the rotating rod to release the lock on the sliding cover, the sliding frame and the sealing component remain in their original positions.

[0013] It is understood that by setting the drive assembly and the manual switch on the sliding cover, this application can not only use the drive assembly to simultaneously drive the sliding cover control assembly and the sealing component to open / close, but also use the manual switch to open the sliding cover. Moreover, by setting the position of the sliding frame and the sealing component unchanged when the manual switch pushes the rotating rod to release the sliding cover lock, the second chamber will not be affected during the manual operation of opening the first chamber, and can maintain a sealed state, thereby avoiding the problem of leakage from the second chamber.

[0014] In one embodiment, the sliding frame includes a first plate, the telescopic rod is disposed through the first plate, and the telescopic rod is capable of driving the sliding frame to slide in the opposite direction to the first direction through the first plate;

[0015] When the rotating rod locks the sliding cover, a preset gap is formed between the first plate and the part of the telescopic rod that abuts against the transmission plate in the first direction.

[0016] In one embodiment, the manual switch includes a push rod that passes through the slide cover and extends downward;

[0017] The rotating rod is provided with a pushing part, which can abut against the pushing rod for a limiting position, and the manual switch can push the pushing part through the pushing rod to drive the rotating rod to release the lock on the sliding cover.

[0018] In one embodiment, the manual switch is slidably connected to the sliding cover;

[0019] The manual switch and the sliding cover are provided with an elastic element, and the manual switch can be reset by the push of the elastic element.

[0020] In one embodiment, the sliding frame further includes a second plate, and a pushing slope is formed on one end of the sliding frame on the transmission plate, and the sliding frame can push against the pushing slope through the second plate to drive the rotating rod to release the lock on the sliding cover.

[0021] In one embodiment, the sliding frame further includes a connecting rod that extends along the first direction and is connected to the second plate.

[0022] The sealing component is connected to the connecting rod body in a sleeve manner and abuts against and limits the second plate body.

[0023] In one embodiment, the transmission plate includes a connecting cylinder that is sleeved on the rotating rod and engages with the keyway of the rotating rod.

[0024] In one embodiment, the connecting cylinder is provided with a plurality of connecting spring clips, which are distributed sequentially at intervals along the circumferential direction of the connecting cylinder; and the rotating rod can simultaneously pass through the plurality of connecting spring clips and then abut against and limit the movement of each of the plurality of connecting spring clips.

[0025] Understandably, by using multiple circumferentially spaced spring clips to achieve elastic clamping between the output end and the rotating rod, the assembly process of the transmission plate and the rotating rod is simplified, allowing for quick installation and fixation without the need for additional fasteners. This also improves the matching accuracy between the two during transmission and the reliability of long-term connection.

[0026] In one embodiment, the telescopic drive is configured as a solenoid valve;

[0027] The solenoid valve integrates a return spring, which is used to control the telescopic rod to return to its original position.

[0028] This application also provides the following technical solutions:

[0029] A dishwasher includes a dispenser as described in any of the above embodiments.

[0030] Compared with the prior art, the dispenser, by setting a drive assembly and a manual switch on the sliding cover, can not only use the drive assembly to simultaneously drive the sliding cover control assembly and the sealing component to open / close, but also use the manual switch to open the sliding cover. Moreover, by setting that when the sliding cover is unlocked by pushing the rotating rod with the manual switch, the positions of the sliding frame and the sealing component remain unchanged, so that the second chamber is not affected during the manual operation of opening the first chamber, and can maintain a sealed state, thereby avoiding the problem of leakage from the second chamber.

[0043] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0047] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0048] This application provides a dispenser 100 for controlling the quantitative dispensing of a first dishwashing medium and a second dishwashing medium. Specifically, the dispenser 100 is installed inside the dishwasher door, and its working position changes synchronously with the opening and closing of the door. When the door is open, the dispenser 100 is in a horizontal position, facilitating the user to add the first and second dishwashing media to their respective dispensing ports. After the door is closed, the dispenser 100 turns to a vertical position and enters a dispensing mode. The dispenser 100 is electrically connected to the dishwasher's main control board for signal transmission and power supply. When the dishwasher reaches the detergent dispensing step, the main control board sends a control signal to the dispenser 100, which then dispenses the first and second dishwashing media in a quantitative manner. Here, the first dishwashing medium is detergent (or dishwashing tablets, powder, or liquid), and the second dishwashing medium is rinse aid.

[0049] like Figures 1 to 9As shown, the dispenser 100 includes: a housing 10, a sliding cover 20, a sliding cover control assembly 30, a sealing element 40, and a drive assembly 50. The housing 10 has a first chamber 11 and a second chamber 12 that are independently arranged. The sliding cover 20 is slidably connected to the housing 10 and is used to open / close the first chamber 11. A manual switch 21 is movably connected to the sliding cover 20. The sliding cover control assembly 30 includes a rotating rod 31 and a transmission plate 32. The rotating rod 31 is rotatably mounted on the housing 10 and can engage with the sliding cover 20 to control the locking / unlocking of the sliding cover 20. Furthermore, one end of the rotating rod 31 facing the sliding cover 20 can also abut against the manual switch 21. One end of the moving rod 31 away from the sliding cover 20 is connected to the transmission plate 32; the sealing member 40 is used to control the opening / closing of the second chamber 12; the drive assembly 50 includes a telescopic drive member 51 and a sliding frame 52. The telescopic rod 511 of the telescopic drive member 51 extends into the sliding frame 52 in the first direction x and abuts against the transmission plate 32 for limitation. The sliding frame 52 is slidably connected to the box body 10 in the first direction x and is connected to the sealing member 40. The sliding frame 52 can simultaneously drive the sealing member 40 and the transmission plate 32 to move. When the manual switch 21 pushes the rotating rod 31 to release the lock on the sliding cover 20, the sliding frame 52 and the sealing member 40 remain in the same position.

[0050] As can be seen from the above, by setting the drive assembly 50 and the manual switch 21 on the sliding cover 20, this application can not only use the drive assembly 50 to simultaneously drive the sliding cover control assembly 30 and the sealing member 40 to open / close, but also use the manual switch 21 to open the sliding cover 20. Moreover, by setting the position of the sliding frame 52 and the sealing member 40 unchanged when the manual switch 21 pushes the rotating rod 31 to release the sliding cover 20 from locking, the second chamber 12 can be kept unaffected during the manual operation of opening the first chamber 11, thus maintaining a sealed state and avoiding the problem of leakage from the second chamber 12.

[0051] like Figures 1 to 4 As shown, in one embodiment, the dispenser 100 housing 10 includes an upper housing 13 and a lower housing 14, with a first sealing ring (not shown) provided between the upper housing 13 and the lower housing 14, which ensures the overall sealing of the housing 10.

[0052] like Figure 2 and Figure 4 As shown, in one embodiment, the upper housing 13 is recessed inward to form a first chamber 11, which is used to store a first dishwashing medium; the sliding cover 20 is slidably connected to the upper housing 13, and the sliding cover 20 is provided with a second sealing ring 16, which can ensure the sealing of the sliding cover 20 to the first chamber 11 after the sliding cover 20 is closed.

[0053] Meanwhile, the upper housing 13 has a notch 17 at the corresponding position of the first chamber 11. When the dishwasher performs the pre-wash process, the water sprayed into the dishwasher tub can enter the first chamber 11 through the notch 17, thereby pre-dissolving the first dishwashing medium in the first chamber 11 so that it can quickly take effect when the first dishwashing medium is added later.

[0054] like Figure 4 , Figure 6 and Figure 9 As shown, the manual switch 21 includes a push rod 211 that passes through the sliding cover 20 and extends downwards. The rotating rod 31 has a push portion 311 that engages with the push rod 211 for limiting its position. The manual switch 21 can push against the push portion 311 via the push rod 211, thereby causing the rotating rod 31 to release the lock on the sliding cover 20. Thus, when the manual switch 21 is moved, the cooperation of the push rod 211 and the push portion 311 drives the rotating rod 31 to rotate smoothly, thereby releasing the lock on the sliding cover 20.

[0055] In one embodiment, a manual switch 21 is slidably connected to a sliding cover 20; wherein an elastic element 22 is provided between the manual switch 21 and the sliding cover 20, and the manual switch 21 can be reset under the push of the elastic element 22.

[0056] Preferably, the elastic element 22 is configured as a spring.

[0057] In one embodiment, the rotating rod 31 is provided with a hook 312, and the sliding cover 20 is provided with a hook engagement part 23. The rotating rod 31 achieves the locking and limiting of the sliding cover 20 through the locking engagement of the hook 312 and the hook engagement part 23.

[0058] like Figure 4As shown, in one embodiment, the box body 10 has a first sliding groove 18 and a second sliding groove 19, which are connected by an arc transition design. Sliding protrusions 24 are formed on both sides of the sliding cover 20. Sliding is achieved through the cooperation of the sliding protrusions 24 with the first sliding groove 18 and the second sliding groove 19. To enable automatic opening of the sliding cover 20 after unlocking, a torsion spring 25 is installed between the box body 10 and the sliding cover 20. One end of the torsion spring 25 is fixed to the box body 10, and the other end is fixed to the sliding cover 20. The torsion spring 25 always possesses an elastic restoring force to drive the sliding cover 20 to move. When the sliding cover 20 is closed, the hook 312 can engage and abut against the hook engagement part 23. Under the limiting action of the hook 312, the torsion spring 25 cannot drive the sliding cover 20 to move, and the sliding cover 20 is locked on the box body 10. When the hook 312 disengages from the hook engagement part 23, the sliding protrusion 24 moves along the first slide groove 18 and the second slide groove 19 under the force of the torsion spring 25 to open the second chamber 12. It should be noted that the illustration of the torsion spring 25 in this application is only for structural display and does not represent its actual installation position; the specific way in which the torsion spring 25 drives the sliding cover 20 to move when it is working can be achieved by conventional technical means in the art, and will not be elaborated here.

[0059] like Figure 5 , Figures 7 to 9 As shown, the transmission plate 32 includes a connecting cylinder 321, which is sleeved on the rotating rod 31 and engages with the keyway of the rotating rod 31.

[0060] Furthermore, the connecting cylinder 321 and the rotating rod 31 are circumferentially limited. The rotating rod 31 is provided with a protruding rib 313, and the connecting cylinder 321 is provided with a matching groove 323. The protruding rib 313 and the groove 323 form a snap-fit ​​fit, so that the connecting cylinder 321 and the rotating rod 31 are circumferentially limited and cannot rotate relative to each other. This allows the rotating rod 31 and the transmission plate 32 to rotate synchronously and precisely together.

[0061] Here, the connecting cylinder 321 is provided with multiple connecting spring clips 3211, which are distributed sequentially and at intervals along the circumferential direction of the connecting cylinder 321. Furthermore, the rotating rod 31 can simultaneously pass through multiple connecting spring clips 3211 and then abut against and be limited by each of the connecting spring clips 3211. Thus, by using multiple circumferentially spaced connecting spring clips 3211 to achieve elastic clamping between the output end and the rotating rod 31, the assembly process of the transmission plate 32 and the rotating rod 31 is simplified, allowing for quick installation and fixation without the need for additional fasteners. This also improves the fitting accuracy and long-term connection reliability during transmission. The number of connecting spring clips 3211 can be configured as four, six, eight, etc.

[0062] like Figure 3 and Figure 7 , Figure 8As shown, the sliding frame 52 includes a first plate 521, and a telescopic rod 511 is provided through the first plate 521. The telescopic rod 511 can drive the sliding frame 52 to slide in the opposite direction of the first direction x through the first plate 521. When the rotating rod 31 locks the sliding cover 20, a preset gap 53 is formed between the first plate 521 in the first direction x and the part of the telescopic rod 511 that abuts against the transmission plate 32.

[0063] In one embodiment, the sliding frame 52 further includes a second plate 522, and a pushing slope 322 is formed on the transmission plate 32 at one end of the sliding frame 52 facing the second plate 522. The sliding frame 52 can push against the pushing slope 322 through the second plate 522 to drive the rotating rod 31 to release the lock on the sliding cover 20.

[0064] In one embodiment, the sliding frame 52 further includes a connecting rod 523, which extends along a first direction x and connects to the second plate 522. The sealing member 40 is connected to the connecting rod 523 in a sleeved manner and abuts against the second plate 522 for limitation. In other words, this embodiment directly sleeves and fixes the sealing member 40 onto the connecting rod 523 of the sliding frame 52. This allows the connecting rod 523 to not only provide stable installation support and movement guidance for the sealing member 40, but also to achieve synchronous driving of the sealing member 40 and the sliding cover control assembly 30 by the telescopic rod 511. This enables the dispenser 100 to reliably control the liquid discharge actions of the first chamber 11 and the second chamber 12 separately using a single drive assembly 50, thereby improving the overall space utilization of the dispenser 100.

[0065] Specifically, the process of the telescopic drive 51 driving the first chamber 11 and the second chamber 12 to release liquid is as follows: When the first chamber 11 and the second chamber 12 are in the closed state and need to be opened, the telescopic drive 51 moves in the opposite direction of the first direction x. The second plate 522 drives the connecting rod 523 and the transmission plate 32 to move synchronously, causing the sealing member 40 to move in the opposite direction of the first direction x to open the second chamber 12. This also causes the rotating rod 31 to rotate, disengaging the hook 312 from the hook engagement part 23, allowing the sliding cover 20 to move and open the first chamber 11. After a preset time, the telescopic drive 51 moves in the first direction x, pushing the connecting rod 523 to drive the sealing member 40 to move in the first direction x to seal the second chamber 12. This process is repeated multiple times to intermittently release the second dishwashing medium, but the first chamber 11 remains open and unaffected. This process also involves a brightener release structure, which is common in existing technology and will not be described in detail here.

[0066] like Figure 8As shown, the telescopic drive component 51 is configured as a solenoid valve, which integrates a return spring 512. The return spring 512 is used to control the return of the telescopic rod 511. Furthermore, the solenoid valve also includes a solenoid coil 513, a fixed iron core 514, and a movable iron core 515. The telescopic rod 511 is integrated into the movable iron core 515 and is integrally formed with it. Under the cyclic control of on / off power, the solenoid coil 513 drives the movable iron core 515 to engage and release with the fixed iron core 514, thereby realizing the continuous telescopic movement of the telescopic rod 511. In other embodiments, the telescopic drive component 51 can also be configured as a telescopic motor, a hydraulic cylinder, or other actuator capable of controlling the telescopic movement of the telescopic rod 511.

[0067] In this embodiment, the reset spring 512 is disposed between the fixed iron core 514 and the movable iron core 515, with one end abutting against the fixed iron core 514 and the other end abutting against the movable iron core 515. The movable iron core 515 can extend along the first direction x or retract along the second direction under the drive of the fixed iron core 514. By setting the reset spring 512 along the moving direction of the movable iron core 515, the reset spring 512 is precisely accommodated and restricted between the two iron cores, and the bending, deflection or jamming of the reset spring 512 during compression and release can be prevented, ensuring that the movable iron core 515 moves smoothly and linearly along the axis.

[0068] In other embodiments, the telescopic rod 511 can also be reset in other ways, such as by providing a reset part 324 on the transmission plate 32, and by providing a structure such as a spring or push rod with one end connected to the box 10 and the other end connected to the reset part 324, so that the transmission plate 32 can drive the telescopic rod 511 to reset.

[0069] This application also provides the following technical solutions:

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application.
