Description

Technical Field

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

[0002] As a kitchen appliance, dishwashers offer a convenient way to relax after meals and are increasingly popular with end users. The detergent dispenser is a crucial component, responsible for dispensing detergent and rinse aid into the dishwasher's drum at set times and in precise quantities during the wash cycle. Controlling the amount dispensed directly impacts the washing results, reduces unnecessary waste of consumables, and lowers operating costs. Simple operation and a superior user experience also enhance the overall experience of using the dishwasher. The detergent dispenser performs two functions: dispensing detergent and rinse aid. Since these are added to the drum at different stages of the wash cycle, the dispenser needs two separate dispensing chambers and inlets. To ensure the dispenser is as easy to use as possible and improve the user experience, the detergent dispenser is designed with these features in mind.

[0003] However, the following defects are common in existing technologies:

[0004] The detergent dispensers currently available on the market are installed in the washing basket or other parts of the inner wall. However, this structure is inconvenient for adding detergent, and its complexity can also take up the limited washing space inside the dishwasher. In severe cases, it can interfere with the flow of washing water or affect the placement and washing process of tableware.

[0005] Current dishwasher detergent dispensers have separate chambers for detergent and rinse aid, but each chamber has its own lid. Every time you add detergent, you need to open the lids for detergent and rinse aid separately, add the detergent, and then close them again, resulting in repetitive and cumbersome operations that reduce the user experience.

[0006] In view of this, the present invention is proposed. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a dishwasher detergent dispenser and dishwasher. When the user needs to close the lid, he / she only needs to close the decorative cover of the detergent dispenser, and its internal push-top structure will automatically close the lid, reducing the operation steps and improving the user experience.

[0008] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0009] A dishwasher detergent dispenser includes a housing and an outwardly flip-up decorative cover. The decorative cover has a chamber, and the chamber dispensing opening has a cover plate. The housing has a push-pull structure that abuts against the cover plate.

[0010] Furthermore, the pushing structure includes a base, a spring, and a fixing rod. The base is fixed to the top of the housing, one end of the spring is fixed to the base, and the other end is fitted onto the fixing rod.

[0011] Furthermore, the fixing rod has a horizontally outwardly extending flange on its outer periphery, and the flange abuts against the housing.

[0012] Furthermore, the fixing rod extends downward through the top of the housing, with the extended end abutting against the closed cover plate.

[0013] Furthermore, the cover plate has a rotating shaft on the side away from the decorative cover, and the rotating shaft is hinged to the edge of the dispensing port.

[0014] Furthermore, the rotating shaft is fitted with a torsion spring, one end of which is connected to the cover plate and the other end of which is connected to the cavity.

[0015] Furthermore, the decorative cover is hinged to the housing with its bottom edge as an axis, and the opening and closing rotation directions of the cover plate and the decorative cover are opposite.

[0016] Furthermore, the inlet of the chamber is gradually inclined, with the highest point on the side closer to the decorative cover and the lowest point on the side farther from the decorative cover. The cover plate is fastened to the upper part of the inlet and abuts against the end of the push-top structure.

[0017] Furthermore, a corresponding groove is provided on the upper end of the housing, and a switch structure is also provided on the upper end of the decorative cover, which engages with the groove.

[0018] To achieve the above objectives, the present invention also provides a dishwasher, including a cabinet, a door, an inner liner, a dish rack, and a spray structure, and is equipped with the aforementioned dishwasher detergent dispenser.

[0019] Preferably, the detergent dispenser is installed on the inner drum of the dishwasher.

[0020] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0021] 1. When using the detergent dispenser, if the user wants to close the chamber cover of the detergent dispenser, simply close the decorative cover of the detergent dispenser. The push-top structure will press the chamber cover tightly, ensuring that the cover closes synchronously with the decorative cover, reducing the user's operation steps and improving the user experience.

[0022] 2. When using the detergent dispenser, opening the decorative cover will cause the chamber cover to spring open via a torsion spring, ensuring that it opens synchronously with the decorative cover. A push-top mechanism is also included to ensure that when the detergent dispenser is turned off, the cover closes synchronously with the decorative cover, providing a better user experience.

[0023] 3. The push-top structure is equipped with a spring. During the use of the washing dispenser, the push-top structure is always pressed against the cover plate by the spring, which increases the airtightness of the cover plate.

[0024] 4. The dishwasher detergent chamber and rinse aid box are set behind the cover, making reasonable use of space and resulting in a compact structure.

[0025] At the same time, the present invention has a simple structure, significant effects, and is suitable for widespread use.

[0026] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] like Figures 1 to 6 As shown in the embodiment of the present invention, a dishwasher detergent dispenser is introduced. The detergent dispenser is fixed to the side wall of the inner tub and includes a housing 1 and a decorative cover 9 that can be flipped outward. A chamber 5 is opened on the rear side of the decorative cover 9, and a cover plate 2 is also provided at the dispensing port of the chamber 5. A dishwasher detergent chamber 4 is also provided on the side of the chamber 5. A push-top structure 3 is also installed inside the housing 1. In this embodiment of the present invention, the push-top structure 3 extends downward from the inner top wall of the housing 1. When the extended end of the push-top structure 3 is engaged with the cover plate 2 on the side closer to the decorative cover 9, the push-top structure 3 is engaged with the cover plate 2 on the side closer to the decorative cover 9. The aforementioned components are sequentially installed onto the detergent additive housing 1 to form the complete detergent dispenser. When detergent needs to be added, the user needs to open the decorative cover 9. During the flipping of the decorative cover 9, the cover plate 2 opens simultaneously with the decorative cover 9. At this time, dishwasher detergent and rinse aid are poured into the detergent chamber 4 and chamber 5 respectively. After adding, simply close the decorative cover 9, and the push-top structure 3 will apply a force to close the cover plate 2 automatically, reducing operation steps and improving user experience. During dishwasher operation, dishwasher detergent and rinse aid can flow into the inner drum, mixing with the cleaning water in the inner drum, thereby improving the dishwasher's cleaning effect.

[0040] To facilitate the addition of dishwasher detergent and rinse aid, in this embodiment, the detergent dispenser is fixedly installed in the lower middle position of the front side wall of the inner drum, near the bottom of the drum. This optimizes the use of the dishwasher's internal space, meeting the height requirements for detergent and rinse aid without affecting the flow of washing water. Alternatively, depending on the internal structure, the detergent dispenser can be placed in a location with lower space utilization but easy to add detergent, either fixed at any position on the front side wall of the inner drum or in a convenient location on any side wall of the inner drum for adding detergent.

[0041] Because dishwasher detergent and rinse aid are continuously consumed during operation, the dishwasher needs to run only when the detergent and rinse aid are depleted. At the appropriate time, the control board sends an electrical signal to the drive motor, at which point detergent and rinse aid are added to the detergent dispenser. In this embodiment, the dishwasher detergent dispenser includes a housing 1, which contains a detergent chamber 4 and a rinse aid chamber 5 for storing detergent and rinse aid respectively. The back of the housing 1 is typically fixed to the side wall of the inner tub using a detachable method such as threaded fastening or snap-fit ​​connection. Dispensing ports are provided on the detergent chambers 4 and 5, with the dispensing ports located at the top of the detergent chambers 4 and 5. A liquid outlet is also provided on the bottom wall of the detergent chamber 4, and a rinse aid outlet is provided at the bottom of the rinse aid chamber 5, facilitating the outflow of detergent and rinse aid. Example

[0042] like Figures 1 to 6 As shown in the embodiment of the present invention, a dishwasher detergent dispenser is introduced, comprising a housing 1 and a decorative cover 9 that can be flipped outward. A chamber 5 is provided on the rear side of the decorative cover 9, and a cover plate 2 is provided at the dispensing port of the chamber 5. A push-top structure 3 is provided inside the housing 1 in the flipping direction of the cover plate 2 to press and fasten it.

[0043] In this embodiment of the invention, the push-top structure 3 includes a base 6, a spring 7, and a fixing rod 8. The base 6 is fixed to the top of the housing 1, and one end of the spring 7 is fixed to the base 6, while the other end is fitted onto the fixing rod 8. When the fixing rod 8 contacts the cover plate 2, the spring 7 is compressed and simultaneously provides a reaction force to close the cover plate 2, ensuring that when the decorative cover 9 is closed, the push-top structure 3 simultaneously closes the cover plate 2 as well, reducing the user's operation steps.

[0044] The fixing rod 8 has a horizontally extending flange 10 on its outer periphery, which abuts against the housing 1. The flange 10 makes the overall push-top structure 3 more stable. The fixing rod 8 extends downward through the top of the housing 1. As the decorative cover 9 is closing, the cover plate 2 gradually comes into contact with the fixing rod 8. When the decorative cover 9 is fully closed, the extended end abuts against the closed cover plate 2, and the spring force of the spring 7 presses the cover plate 2 tightly, ensuring the cover plate 2 is sealed. By setting the spring 7, only when the fixing rod 8 and the cover plate 2 generate appropriate elastic force in the appropriate position can the wear between the fixing rod 8 and the cover plate 2 be reduced, thus improving the service life of the product. At the same time, the cover plate 2 can be made of nylon wear-resistant material, and the extended end of the fixing rod 8 is set as a smooth end, which can further reduce the wear between the fixing rod 8 and the cover plate 2.

[0045] The chamber 5 has two through holes at the dispensing port. The cover plate 2, on the side away from the decorative cover 9, has a rotating shaft 12 connected to the dispensing port. A torsion spring 13 is fitted onto the rotating shaft 12. One end of the torsion spring 13 is connected to the cover plate 2, and the other end is connected to the chamber 5, hinged to the cover plate 2. During the closing process of the cover plate 2, the torsion spring 13 generates a force opposite to the closing direction. When the cover plate 2 is closed, the torsion spring 13 is in a tightened state. When the decorative cover 9 is opened, the cover plate 2, driven by the torsion spring 13, quickly springs open, and through the pushing structure 3, ensures that the cover plate 2 and the decorative cover 9 open and close synchronously, improving product competitiveness and reducing user operation steps. After the brightener is dispensed, the cover plate 2 seals the brightener box, preventing washing water from entering the brightener box during dishwasher operation.

[0046] In this embodiment of the invention, the dishwasher detergent chamber 4 is open and does not have a cover. In other embodiments, a cover may be provided, and its design principle is the same as that of chamber 5, which can also satisfy the requirement that the cover opens simultaneously when the decorative cover 9 is opened, and close simultaneously when the decorative cover 9 is closed. A liquid outlet is provided on the bottom wall of the dishwasher detergent chamber 4. After the dishwasher detergent placed in the chamber 4 comes into contact with the washing water, it flows out from the liquid outlet into the dishwasher tub. In this embodiment, the liquid outlet is located on the bottom wall of the dishwasher detergent chamber 4. The dishwasher detergent chamber 4 includes vertically arranged side walls, the bottom of which is connected to the bottom wall. The bottom wall and the bottom of the side walls are completely sealed and integrally formed.

[0047] like Figure 2 As shown, a chamber 5, or rinse aid box, is formed inside the housing 1 next to the dishwasher detergent chamber 4. Under normal conditions, the rinse aid box opening is fitted with a sealing ring and sealed by the cover plate 2. The rinse aid box is funnel-shaped, which facilitates the flow of rinse aid while ensuring that no rinse aid residue remains.

[0048] like Figure 5As shown, the rinse aid box is located inside the housing 1, while the solenoid valve (not shown in the figure) is located below the rinse aid box opening. This makes full use of the limited space of the housing 1 and allows for the installation of the largest possible rinse aid box with the least amount of space occupied. Alternatively, the solenoid valve can be placed below the dishwasher detergent chamber 4.

[0049] In this embodiment, to cooperate with the push-top structure 3, the cover plate 2 has a rotating shaft 12 on the side away from the decorative cover 9, which is hinged to the edge of the dispensing port. Simultaneously, the decorative cover 9 has a hinge shaft 14 on its bottom edge, which is hinged to the housing 1. This ensures that the cover plate 2 and the decorative cover 9 are arranged in opposite directions of opening and closing. The distance from the rotating shaft 12 to the hinge shaft 14 on the side of the cover plate 2 away from the decorative cover 9 is less than the distance from the push-top structure 3 to the hinge shaft 14. This ensures that during the closing or opening of the decorative cover 9, the push-top structure 3 will not come into contact with the side of the cover plate 2 away from the decorative cover 9, thus preventing difficulty in opening or closing the decorative cover 9 as a whole.

[0050] The housing 1 has a groove corresponding to the decorative cover 9, which accommodates the chamber 5 when the decorative cover 9 is flipped and closed. The push-top structure 3 is located on the top of the cover plate 2 near the front side of the groove in the housing 1. The distance from the side of the top surface of the cover plate 2 near the decorative cover 9 to the hinge shaft 14 is not less than the distance from the push-top structure 3 to the hinge shaft 14. In this way, when the user closes the decorative cover 9, the push-top structure 3 applies a force to the open cover plate 2 to close it. The cover plate 2 will cover the brightener box, but it is not completely sealed at this time. As the decorative cover 9 is gradually pushed in, the cover plate 2 will gradually contact the push-top structure 3. At the highest point, the push-top structure 3 will abut against the closed cover plate 2. By gradually pressing down the cover plate 2 through the push-top structure 3, it is not necessary to close the cover plate 2 first and then close the decorative cover 9. Closing the decorative cover 9 will automatically close the cover plate 2, reducing the operation process and improving the user experience. Moreover, the push-top structure 3 is simple in design and structure, and the spring 7 always applies pressure to the cover plate 2, resulting in a good sealing effect.

[0051] Common dishwasher detergents are powder or tablets, not regular household dish soap. Powder is the most frequently used detergent in dishwashers. To ensure smooth flow of the powder through the outlet, preventing undissolved powder from remaining at the junction of the bottom and side walls, and to maximize contact between the powder and water, extending the melting path and fully forming the detergent solution, the bottom wall can be designed as a concave arc shape. Ideally, the side walls and bottom wall should be designed as a single, continuous arc, with the lowest point near the outlet. The junctions of the side walls should also be arc-shaped for a smooth transition. The shape of the powder chamber 4 can be designed in various forms, such as a cylinder or polygon. For convenient powder flow, the bottom wall is still recommended to be sloped, preferably curved.

[0052] In this embodiment of the invention, the housing 1 has mounting holes on both sides, and the bottom edge of the decorative cover 9 is provided with a hinge shaft 14. The hinge shaft 14 is inserted into the mounting hole to ensure that the decorative cover 9 can rotate around the shaft, and the rotation angle is about 45°.

[0053] In this invention, the upper end of the decorative cover 9 is also provided with a switch structure 11, and the upper end of the housing 1 is provided with a corresponding groove, the switch structure 11 cooperating with the groove. When the user needs to add dishwashing powder and rinse aid, he / she only needs to open the decorative cover 9 to add them. After adding, the decorative cover 9 will engage with the groove on the housing 1 to close.

[0054] like Figures 1 to 6 As shown, in this embodiment of the invention, the dishwasher detergent chamber 4 is open and has no cover. Therefore, users are required to manually add dishwasher detergent each time they use it. To prevent users from adding too much detergent, resulting in detergent residue on the dishes after washing, or adding too little detergent, resulting in inadequate washing, a dosage indicator can be set inside the dishwasher detergent chamber 4. For example, a dosage indicator can be set on the side wall to clearly indicate the dosage. In this embodiment of the invention, due to the limited width of the outlet, it is recommended to use only dishwasher detergent in the dishwasher detergent chamber 4 and not to use detergent tablets. Therefore, in this embodiment, a dosage indicator column is set inside the dishwasher detergent chamber 4.

[0055] In this embodiment of the invention, a measuring column, in a stepped shape, is provided on the bottom wall of the dishwasher detergent chamber 4. Different heights of the measuring column represent different amounts of dishwasher detergent used, i.e., the amount of detergent. When dishwasher detergent is placed in the dishwasher detergent chamber 4, in practical applications, one or more measuring columns can be provided on the bottom wall. In this embodiment of the invention, only one measuring column is provided, but the volume of the measuring column and the volume of the detergent dispenser are determined according to specific circumstances to ensure accurate dosage. In this embodiment of the invention, the measuring column can indicate the dosage and, on the other hand, can also force or prompt the user to use only dishwasher detergent in this dishwasher detergent chamber 4 and not detergent tablets, thus preventing the user from mistakenly adding detergent tablets to the detergent dispenser, causing the detergent tablets to not dissolve completely. Example

[0056] The detergent dispenser is installed on the inner wall of the dishwasher's drum, preventing it from being soaked or leaking during use, and improving the utilization of internal space. The detergent dispenser's decorative cover 9 has a detergent powder chamber 4 and a chamber 5 located on its rear side. In use, opening the decorative cover 9 causes the cover plate 2 to automatically pop open, allowing the corresponding detergent to be added to the detergent powder chambers 4 and 5 respectively. Then, the decorative cover 9 is closed. During the closing process, the side of the cover plate 2 closest to the decorative cover 9 gradually abuts against the extension end of the fixing rod 8. When the decorative cover 9 is almost completely closed, the pushing structure 3 exerts its maximum closing force on the cover plate 2, until the cover plate 2 is completely covered. Finally, the switch structure 11 is engaged.

[0057] In this embodiment of the invention, when the cover plate 2 is opened to add brightener, the cover plate 2 is rotated at an angle of less than 90° and remains open; the included angle between the decorative cover 9 and the radial plane of the shell 1 is 45°. The 45° outward protrusion is in line with ergonomic design, making it more convenient to add brightener when the cover plate 2 is open, and allowing direct observation of the internal liquid level to facilitate control of the amount added.

[0058] During use, washing water enters through the inlet, then flows through the inlet channel and water injection hole into the dishwasher detergent chamber 4. The dishwasher detergent in the chamber 4 is dissolved by the washing water and flows out through the outlet, which is located on the bottom wall of the dishwasher detergent chamber 4 for easy discharge. Next to the dishwasher detergent chamber 4 is chamber 5, which has a compact structure and makes good use of space. Simply open the cover 2 to add the detergent, which is convenient. The dispensing port of chamber 5 is set at an angle downwards, with the highest port near the decorative cover 9 and the lowest port away from the decorative cover 9, which facilitates the addition of detergent and also works in conjunction with the push-top structure 3 to prevent detergent leakage.

[0059] In this embodiment of the invention, the chamber 5 can open and close automatically without requiring any additional operation from the user, greatly reducing the user's operation steps and improving the user experience.

[0060] The bottom of chamber 5 is also provided with a brightener outlet, which is connected to chamber 5 through a conduit. The housing 1 is provided with a solenoid valve that cooperates with the conduit. When the solenoid valve is not energized, the valve core of the solenoid valve is tightly pressed against the conduit to block the conduit. When the solenoid valve is energized, the valve core of the solenoid valve separates from the conduit, the conduit opens, and the brightener in chamber 5 is discharged from the brightener outlet through the conduit. By controlling the solenoid valve, the opening and closing of the conduit can be controlled, thereby controlling the brightener dispensing time and amount.

[0061] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. The implementation schemes in the above embodiments can be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
