Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, and in particular to a detergent dispensing device for a dishwasher and the dishwasher. Background Art

[0002] There are many types of detergents for dishwashers, among which dishwashing powder is more popular among users because the dosage can be freely controlled according to the number of dishes and the degree of grease during use, and the price per use is relatively low. However, existing dishwashers can only add dishwashing powder once in a cleaning cycle, and a cleaning cycle will use up all the dishwashing powder, so dishwashing powder needs to be added again in each cycle, which is relatively cumbersome for users to operate. For users who do not have a measuring device at home, dishwashing powder cannot be added in a quantitative manner, the amount of dishwashing powder cannot be controlled, and it also affects the cleaning effect of the dishwasher.

[0003] At present, the above problems are generally solved by setting an automatic dispensing device, such as the dispensing device disclosed in the utility model with patent number 202020684594.3 (authorization announcement number CN 212186427 U), which includes a connected storage chamber and a dispensing chamber, the storage chamber is used to store detergent, a hollow rotating structure is provided in the dispensing chamber, a material cup is arranged in the rotating structure, and a driving structure is also included, the driving structure is fixed in the dispensing chamber, and the driving structure is connected to the rotating structure to drive the rotating structure to rotate so that the material cup dispenses detergent. The amount of material dispensed each time is the total amount of detergent in the material cup. The opening direction of the material cup is driven by the driving structure to rotate multiple times between the upper and lower parts, and the dispensing device realizes quantitative, multiple, and automatic dispensing of detergent. However, since the unit feeding amount is equal to the volume of the material cup, the dispensing device cannot dispense materials in smaller units, and its feeding accuracy is limited. During the rotation of the rotating structure, the material storage chamber always has a tendency to replenish detergent downward. When the opening of the material cup is not in an upward state, the detergent will flow into the gap between the front cover, the rear cover and the rotating structure, which may cause the dispensing device to fail to operate normally. It is not easy to maintain a good dynamic seal without affecting the rotation of the rotating structure. Utility Model Content

[0004] The first technical problem to be solved by the utility model is to provide a detergent feeding device with a further reduced unit feeding volume and in which detergent will not accumulate in the gap and affect the rotation of the rotating structure in view of the above technical status quo.

[0005] The second technical problem to be solved by the utility model is to provide a dishwasher using the above-mentioned detergent dispensing device.

[0006] The technical solution adopted by the utility model to solve the first technical problem is: a detergent dispensing device for a dishwasher, comprising:

[0007] The material storage device comprises a material storage cavity, the upper part of which is provided with a material inlet for communicating with the outside, and the lower part of which is provided with a material outlet;

[0008] A feeder is located below the accumulator, with a feeding port connected to the discharge port of the accumulator at the upper part, and a feeding port for connecting to the washing chamber of the dishwasher at the lower part, and a feeding chamber for containing detergent between the feeding port and the feeding port;

[0009] It is characterized in that

[0010] The feeding chamber of the feeder is divided into at least two feeding bins arranged along the circumferential direction;

[0011] In addition, it also includes a driving device to drive the feeding bins to rotate circumferentially together, so that the feeding port and the discharge port are respectively connected to the feeding bins, and at the same time, the feeding bin connected to the feeding port is different from the feeding bin connected to the discharge port.

[0012] Specifically speaking, the feeder includes a housing and a feeding tray enclosed in the housing, a feeding cavity is formed between the housing and the feeding tray, a partition plate is provided on the feeding tray, the feeding cavity is divided into mutually unconnected feeding bins, and the driving device drives the feeding tray to rotate. Preferably, the power output shaft of the driving device is driven to penetrate the center of the feeding tray, which can make the rotation more balanced.

[0013] In order to more thoroughly feed the detergent in the feeding bin, further, the feeding port of the feeder is opened at the lower part of the side wall of the cover shell, and the detergent falls into the cleaning operation space of the dishwasher by gravity.

[0014] The utility model realizes quantitative feeding by throwing out detergent from a feeding bin each time, so the diameter of the feeding port should not be set too large. Specifically, the feeding bins are fan-shaped or fan-shaped, and are distributed circumferentially with the center of the feeding disk as the center of the circle. The diameter of the feeding port is not greater than the circumferential arc length of a single feeding bin.

[0015] Detergents such as dishwashing powder are filled into each feeding bin from the storage cavity. In order to make the transfer process of the detergent smoother, the storage cavity is further enclosed by the inner wall surface of the storage container, and the discharge port is opened at the lower inner wall surface. The lower inner wall surface gradually tilts downward from far to near the discharge port to form a funnel-shaped structure. Furthermore, in the utility model, at least one inner wall surface of the storage container extending in a vertical direction gradually tilts toward the discharge port from top to bottom.

[0016] In order to prevent the cleaning water from entering the accumulator through the feed port during the cleaning operation of the dishwasher and wetting the detergent stored in the accumulator, preferably, the accumulator is also provided with a plug capable of sealing and opening the feed port. The user pulls out the plug when adding detergent, and uses the plug to seal the feed port after adding.

[0017] The technical solution adopted by the utility model to solve the second technical problem is: a dishwasher, comprising an inner door, characterized in that the inner door is provided with the above-mentioned feeding device. Specifically, the feeder and the accumulator of the feeding device are arranged on the inner side of the inner door, the driving device is installed on the outer side of the inner door, and its power output shaft passes through the inner door and is connected to the feeder.

[0018] Compared with the prior art, the detergent dispensing device of the present invention adopts a design of multiple feeding bins to replace the material cups in the prior art. The single feeding amount of the dispensing device becomes the volume of a single feeding bin, so the feeding amount during the feeding process can be more accurately controlled. The role of the feeding chamber in the prior art is only to provide a rotating space for the material cup, while the feeding chamber in the present invention serves as both a rotating body and a loading body. Under the same total feeding amount, the dispensing device of the present invention can be smaller in size, significantly saving the internal space occupied by the dishwasher. In addition, since the storage chamber is connected to at least one feeding bin at any time, most detergents can directly enter the feeding bin. Even if a small amount of detergent enters the gap, it can easily enter the feeding bin during rotation. The detergent will not have a negative impact on the operation of the dispensing device, so the present invention does not need to consider the sealing problem. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] like Figure 1-6 The dishwasher comprises a base assembly 100, a box assembly 200, a door assembly 300, an inner tank assembly 400 and a dispensing device 500 for dispensing detergents such as dishwashing powder, etc. Figure 1 The door assembly 300 includes an outer door 310 and an inner door 320, and the delivery device 500 is disposed on the inner door 320. Figure 2 .

[0027] The feeding device 500 includes three main components: a hopper 510, a feeder 520, and a driving device 530. The user directly adds detergent to the hopper 510, and the hopper 510 can be installed on the inner surface of the inner door 320 by various fixing methods, such as a snap structure, a plug-in structure, etc. In this embodiment, the hopper 510 is fixed by a plurality of claws arranged on the inner surface of the inner door 320, which are not expanded here. The feeder 520 is roughly circular and is used to distribute and feed the detergent from the hopper 510 into the washing cavity of the dishwasher. The driving device 530 is a motor in this embodiment. A fixing frame 550 is welded on the outer surface of the inner door 320, and the motor is installed on the fixing frame 550 by screws. The power output shaft 531 of the driving device 530 penetrates the inner door 320 and is connected to the center of the feeder 520.

[0028] like Figures 4 to 6 As shown, the accumulator 510 includes a storage cavity 511, which is enclosed by the inner wall surface 514 of the accumulator 510, with a feed port 512 at the top for communicating with the outside, and a discharge port 513 at the bottom. A plug 515 capable of sealing and opening the feed port 512 is provided at the feed port 512, and the feed port 512 connects the storage cavity 511 with the outside when the plug 515 is pulled out. The discharge port 513 is opened on the inner wall surface 514 at the bottom, and the inner wall surface 514 gradually tilts downward from far to near the discharge port 513 to form a funnel-shaped structure. At the same time, the inner wall surface 514 of the accumulator 510 extending in the vertical direction gradually tilts toward the discharge port 513 from top to bottom.

[0029] The feeder 520 is located below the accumulator 510, and includes a cover 523 and a feed tray 524 enclosed in the cover 523. A feed cavity is formed between the cover 523 and the feed tray 524. A plurality of partition plates 525 are provided on the surface of the feed tray 524, dividing the feed cavity into a plurality of feed bins 526 that are not connected to each other. Each feed bin 526 is a sector with equal volume and is arranged circumferentially with the center of the feed tray 524 as the center of the circle. A feed filling port 521 connected to the discharge port 513 of the accumulator 510 is provided at the upper part of the cover 523, and a feed port 522 connected to the washing cavity of the dishwasher is provided at the lower part. The diameter of the feed port 522 is not greater than the arc length of the circumference of a single feed bin 526. The feeder 520 is fixedly connected to the accumulator 510 . A connecting bracket 540 extending downward is fixed on each side of the accumulator 510 . The cover 520 is connected to the other end of the connecting bracket 540 by screws.

[0030] The power output shaft 531 of the driving device 530 passes through the center of the feeding tray 524 and drives the feeding tray 524 to rotate circumferentially, that is, drives each feeding bin 526 to rotate axially together, so that the feeding port 522 and the discharge port 513 are respectively connected to the corresponding feeding bin 526, and at the same time, the feeding bin 526 connected to the feeding port 522 is different from the feeding bin 526 connected to the discharge port 513.

[0031] The specific operation mode of the feeding device 500 is as follows: the user feeds the detergent into the feed chamber 511 through the feed port 512 of the accumulator 510, and the detergent enters the storage chamber 511 through the feed port 512, and then is filled into the corresponding feeding bin 526 through the discharge port 513 of the accumulator 510 and the replenishing port 521 of the feeder 520, and the driving device 530 drives each feeding bin 526 to rotate a certain angle, and the storage chamber 511 is disconnected from the feeding bin 526 that has just been filled, and is connected to another new feeding bin 526 and continues to add detergent to the new feeding bin 526, and under continuous rotation, the filled feeding bin 526 rotates to the feeding port 522, at which time the feeding bin 526 is connected to the washing chamber below the feeding port 522, and the detergent can be fed into the washing chamber through the feeding port 522, and the whole process is fully automatically controlled except for the initial stage when the user needs to add detergent to the accumulator 510. During the cleaning process, detergent can be added multiple times at specific times according to the needs of the time, and quantitative addition can be achieved with the volume of a single feeding bin 526 as the minimum unit, which solves the inconvenience of users having to add dishwashing powder before each cleaning and improves the user experience. At the same time, this structure can be combined with an intelligent cleaning program to determine how much detergent to add based on intelligent detection of the number of dishes and the degree of dirtiness. At the same time, if it is detected that the items to be washed are not cleaned thoroughly, dishwashing powder and other detergents can be added again to ensure that they are cleaned thoroughly, thereby improving the user experience.
