Description

Technical Field

[0001] The present invention belongs to the technical field of dishwashers, and in particular relates to a dishwasher detergent adder and a dishwasher. Background Art

[0002] As a kitchen appliance, dishwashers are increasingly popular among end users, allowing users to enjoy hands-free relaxation after meals. The detergent dispenser is a crucial component, responsible for regularly and quantitatively dispensing dishwashing powder and rinse aid into the dishwasher's inner tank during the wash cycle. Controlling the amount dispensed by the detergent dispenser determines the washing performance of dishes, while also reducing unnecessary waste of consumables and lowering operating costs. Simple operation techniques and user experience also enhance the overall quality of dishwasher use. The detergent dispenser in a dishwasher must handle both the dispensing of dishwashing powder and rinse aid. Because these two ingredients are added to the inner tank at different stages of the wash cycle, the design of two separate dispensing chambers and ports is crucial. This is to ensure the ease of operation and enhance the user experience.

[0003] However, the following defects are common in the prior art:

[0004] Existing dishwasher detergent dispensers on the market are installed in the washing basket or other parts of the inner wall. However, this structure is inconvenient for adding detergent. On the other hand, due to its complex structure, it occupies the limited cleaning space inside the dishwasher. In serious cases, it may interfere with the flow of washing water or affect the placement and cleaning process of dishes.

[0005] Today's detergent dispensers contain two separate cavities for dishwashing powder and rinse agent, but each cavity has an independent lid. Each time you add dishwashing powder and rinse agent, the user is required to open the lids of the dishwashing powder and rinse agent separately, and then close them separately after adding. This results in repetitive operations, cumbersome movements, and reduces 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 existing technology and provide a dishwasher detergent feeder and a dishwasher. When the decorative cover of the detergent feeder needs to be closed, the tightening structure will automatically close the chamber cover inside the detergent feeder together, thereby reducing the operating steps and improving the user experience.

[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0009] A dishwasher detergent feeder comprises a shell and an outwardly flippable decorative cover, wherein the decorative cover is provided with a second chamber, a cover plate is provided at an inlet of the second chamber, and a tightening structure for pressing and fastening the cover plate in the flipping direction thereof is provided inside the shell.

[0010] Furthermore, the cover plate is hinged to the edge of the loading port with the side away from the decorative cover as the axis, and the decorative cover is hinged to the shell with its bottom edge as the axis, so that the cover plate and the decorative cover are set in opposite directions of opening / closing.

[0011] Furthermore, the housing is provided with a groove corresponding to the decorative cover, and the groove accommodates the second chamber when the decorative cover is flipped and buckled;

[0012] Preferably, the distance from the side of the top surface of the cover plate close to the decorative cover to the hinge axis of the decorative cover is not less than the distance from the tightening structure to the hinge axis of the decorative cover.

[0013] Furthermore, the distance from the side of the cover plate away from the decorative cover to the hinge axis of the decorative cover is smaller than the distance from the tightening structure to the hinge axis of the decorative cover.

[0014] Furthermore, the tightening structure is provided at the top of the cover plate near the front side of the housing groove, and applies a force to the open cover plate to close it when the decorative cover is fastened to the housing.

[0015] Furthermore, the tightening structure is extended downward from the inner top wall of the shell, and the extended end of the tightening structure abuts against the cover plate when the decorative cover is buckled.

[0016] Furthermore, a switch structure is provided at the upper end of the decorative cover, and the switch structure is snap-fitted with the housing.

[0017] Furthermore, a first chamber is provided next to the second chamber. When the decorative cover is buckled, the first chamber and the second chamber are both accommodated in the groove. The first chamber is a dishwashing powder chamber with an open top and a liquid outlet at the bottom of the chamber, and the liquid outlet is connected to the bottom wall from top to bottom.

[0018] Furthermore, a metering column is vertically provided in the first chamber, and the bottom end of the metering column is fixedly connected to the bottom wall of the first chamber.

[0019] To achieve the above object, the present invention also introduces a dishwasher, comprising a housing, a door, an inner container, a dishware rack and a spray structure, and is equipped with the above dishwasher detergent feeder;

[0020] Preferably, the detergent feeder is arranged on the inner container of the dishwasher.

[0021] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0022] 1. Through the above settings, when the decorative cover of the detergent dispenser is closed, the tightening structure will automatically close the second chamber cover, reducing the operation steps and improving the user experience.

[0023] 2. The dishwashing powder chamber is open for easy dispensing.

[0024] 3. The dishwashing powder chamber and the rinse agent chamber are arranged behind the cover, which makes rational use of space and has a compact structure.

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

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0037] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0038] like Figures 1 to 5 As shown, an embodiment of the present invention introduces a dishwasher detergent feeder, which is fixed to the side wall of the inner tank and includes a shell 1 and a decorative cover 14 that can be flipped outward. The rear side of the decorative cover 14 is respectively provided with a first chamber 4 and a second chamber 5. A cover plate 2 is further provided at the inlet of the second chamber 5. A tightening structure 3 is also installed in the shell 1. In the embodiment of the present invention, the tightening structure 3 extends downward from the inner top wall of the shell 1. When the extended end of the tightening structure 3 is buckled with the decorative cover 14, the cover plate 2 close to the decorative cover 14 abuts against each other. The tightening structure 3 is composed of two downwardly protruding ribs, and multiple ribs may be provided. The aforementioned components are sequentially mounted on the detergent additive housing 1 to form the entire detergent dispenser. To add detergent to the detergent dispenser, the user opens the decorative cover 14 and pours dishwashing powder and rinse agent into the first chamber 4 and the second chamber 5, respectively. After adding, the user simply closes the decorative cover 14. The tightening structure 3 applies a force to close the cover plate 2 of the second chamber 5, automatically closing the cover plate 2 as well, reducing the number of steps required and improving the user experience. During operation, the dishwashing powder and rinse agent flow into the inner tank, mixing the clean water in the tank with the dishwashing powder and rinse agent, thereby improving the dishwasher's decontamination performance.

[0039] To facilitate the user's addition of dishwashing powder and rinse aid, in this embodiment, the detergent dispenser is fixedly mounted in the lower center of the front sidewall of the inner tank, near the bottom of the inner tank. This optimizes internal space utilization, meeting the required height of the dishwashing powder and rinse aid without affecting the flow of wash water. Alternatively, depending on the internal structural characteristics, the detergent dispenser can be placed in a location with lower space utilization and convenient for adding dishwashing powder during product design. It can be fixed anywhere on the front sidewall of the inner tank, or on any sidewall of the inner tank, at a location convenient for adding dishwashing powder.

[0040] Since dishwashing powder and rinse agent are continuously consumed during the operation of the dishwasher, the dishwasher needs to be operated when the dishwashing powder and rinse agent are completely consumed. At the appropriate time, the computer board will send an electrical signal to the drive motor, at which time, dishwashing powder and rinse agent are added to the detergent dispenser. In this embodiment, the above-mentioned dishwasher detergent dispenser includes a housing 1, which is provided with a first chamber 4 and a second chamber 5 for storing dishwashing powder and rinse agent, respectively. The back of the housing 1 is generally fixed to the side wall of the inner container by a detachable method such as threaded locking or snap connection; the chambers are respectively provided with a dishwashing powder dispensing port and a rinse agent dispensing port, wherein the dispensing port is located at the top of each chamber, the bottom wall of the first chamber 4 is also provided with a liquid outlet 9, and the bottom of the second chamber 5 has a rinse agent outlet 17, thereby facilitating the outflow of dishwashing powder and rinse agent in the chambers.

[0041] Example 1

[0042] like Figures 1 to 5 As shown, in an embodiment of the present invention, a dishwasher detergent adder is introduced, which includes a shell 1 and a decorative cover 14 that can be flipped outward. A second chamber 5 is provided on the rear side of the decorative cover 14, and a cover plate 2 is provided at the inlet of the second chamber 5. A tightening structure 3 is provided in the shell 1 in the flipping direction of the cover plate 2 to press it tightly.

[0043] The first chamber 4 of the washing additive is open and has no cover. In the embodiment of the present invention, there is no need to specially set up a water path for the first chamber 4. The water source demand of the first chamber 4 can be met by utilizing the existing water path and the injection port of the door body accessories. Of course, other methods can also be provided to provide the water path. A liquid outlet 9 is provided on the bottom wall of the first chamber 4. After the dishwashing powder placed in the first chamber 4 contacts the washing water, it flows out from the liquid outlet 9 into the inner tank of the dishwasher. In the embodiment of the present invention, the liquid outlet 9 is located on the bottom wall of the first chamber 4. The first chamber 4 includes a vertically arranged side wall. The bottom of the side wall is connected to the bottom of the bottom wall. The bottom wall and the bottom of the side wall are completely sealed and connected, forming an integral part.

[0044] like Figure 2As shown, a second chamber 5, i.e., a rinse aid box, is provided in the housing 1 next to the first chamber 4. Under normal conditions, a sealing ring 16 is provided at the mouth of the rinse aid box and sealed by a cover 2 with a snap-on switch 8. The rinse aid box is funnel-shaped, which facilitates the outflow of the rinse aid while ensuring that no rinse aid residue remains.

[0045] The second chamber 5 is provided with a cover plate 2 at the introduction port, and there are two through holes 7 at the introduction port of the second chamber 5. A rotating shaft 6 is provided on the side of the cover plate 2 away from the decorative cover 14. A return spring 13 is sleeved on the rotating shaft 6. One end of the return spring 13 protrudes and is connected to the through hole 7. The rotating shaft 6 passes through the through hole 7, so that the cover plate 2 is hinged to the second chamber 5. When the cover plate 2 needs to be opened, the cover plate 2 will quickly pop open the reversible cover plate 2 under the drive of the return spring 13. After the rinse agent is introduced, the cover plate 2 seals the rinse agent box so that the washing water will not enter the rinse agent box during the operation of the dishwasher. In order to facilitate the opening of the rinse agent box, a snap switch 8 is also provided on the front side of the introduction port. The snap switch 8 can be in the form of a barb, which is snap-fitted with the cover plate 2 to achieve a sealed state.

[0046] like Figure 5 As shown, the brightener box is located inside the housing 1, and the solenoid valve (not shown) is located below the opening of the brightener box. This can fully utilize the limited space of the housing 1 and set the brightener box with the largest volume while occupying the least space possible. Of course, the solenoid valve can also be set below the first chamber 4.

[0047] In this embodiment, to facilitate the use of the tensioning structure 3, the cover plate 2 is provided with a rotation axis 6 on the side away from the decorative cover 14, which is hinged to the edge of the loading port. Simultaneously, the decorative cover 14 is provided with a decorative cover hinge axis 11, which is hinged to the housing 1 along its bottom edge. This allows the cover plate 2 and the decorative cover 14 to open and close in opposite directions. The distance from the rotation axis 6 on the side of the cover plate 2 away from the decorative cover 14 to the decorative cover hinge axis 11 is shorter than the distance from the tensioning structure 3 to the decorative cover hinge axis 11. This ensures that during the closing and opening of the decorative cover 14, the tensioning structure 3 does not interfere with the side of the cover plate 2 away from the decorative cover 14, thereby preventing the entire decorative cover 14 from opening and closing.

[0048] The shell 1 is provided with a groove corresponding to the decorative cover 14, which accommodates the second cavity 5 when the decorative cover 14 is flipped and buckled; the top tight structure 3 is arranged on the top of the shell 1 near the front side of the groove, and the distance from the top surface of the cover plate 2 near the decorative cover 14 to the decorative cover hinge shaft 11 is not less than the distance from the top tight structure 3 to the decorative cover hinge shaft 11. In this way, when the user is closing the decorative cover 14, the top tight structure 3 exerts a force on the open cover plate 2 to make it close. The cover plate 2 will cover the brightener box, but it is not completely sealed at this time. As the decorative cover 14 is gradually pushed in, the cover plate 2 will gradually contact the top tight structure 3. At the highest point, the top tight structure 3 will abut against the cover plate 2 when it is closed. The top tight structure 3 gradually presses down the cover plate 2, so that the barb buckle switch 8 at the pouring opening is easily clamped to the front edge of the cover plate 2. In the use process, the user does not need to close the cover plate 2 before closing the decorative cover 14. Only the decorative cover 14 needs to be closed, and the cover plate 2 can be automatically closed, reducing the operation process and improving the user experience. Moreover, the buckle switch 8 is simple in structure and good in sealing effect.

[0049] The common cleaning agent for dishwashers is dishwashing powder or dishwashing block, and ordinary household detergent cannot be used. In the dishwasher, the most commonly used cleaning agent is dishwashing powder. In order to make the dishwashing powder smoothly pass through the liquid outlet 9, avoid the presence of undissolved dishwashing powder at the connection between the bottom wall and the side wall, and also make the dishwashing powder fully contact with water, prolong the melting path, and fully form a washing solution, the bottom wall can be designed as an arc-shaped concave surface. The best way is to design the side wall and the bottom wall as an integral arc surface. The bottom wall near the liquid outlet 9 is still the lowest point, and the connection between the side walls is also arc-shaped, which is smooth transition. The shape of the first cavity 4 can be designed in various shapes according to specific conditions, such as a cylindrical shape, a polygonal shape, etc. In order to facilitate the outflow of the dishwashing powder, the bottom wall is still recommended to be designed as an inclined surface, preferably an arc surface.

[0050] In the embodiment of the present application, the shell 1 has mounting holes 12 on both sides, and the bottom edge of the decorative cover 14 is provided with a decorative cover hinge shaft 11, which is inserted and mounted in the mounting holes 12 correspondingly, so as to ensure that the decorative cover 14 can be flipped around the shaft, and the flipping angle is about 45°.

[0051] In the embodiment of the present application, the upper end of the decorative cover 14 is further provided with a switch structure 15, and a corresponding groove is formed on the upper end of the shell 1. The switch structure 15 cooperates with the groove. When the user needs to add dishwashing powder and brightener, the decorative cover 14 is opened for pouring. After the pouring is completed, the decorative cover 14 is closed in cooperation with the groove on the shell 1.

[0052] As Figures 1 to 5As shown, in the embodiment of the present invention, the first chamber 4 is open and has no cover, so the user is required to manually add dishwashing powder each time it is used. In order to prevent the user from adding too much, resulting in residual dishwashing powder solution on the dishes after cleaning, or adding too little, resulting in inadequate cleaning, a metering mark with a dosage indication function can be provided inside the first chamber 4, such as a metering mark on the side wall to clearly indicate the dosage. In the embodiment of the present invention, due to the limited width of the liquid outlet 9, it is recommended to only use dishwashing powder in the first chamber 4, and washing blocks cannot be used. Therefore, in this embodiment, a metering column 10 marked with a dosage indication is provided in the first chamber 4.

[0053] In an embodiment of the present invention, a metering column 10 is provided on the bottom wall of the first chamber 4 in a stepped shape. The different heights of the metering column 10 represent different grams of dishwashing powder used, that is, the amount of detergent used. When dishwashing powder is placed in the first chamber 4, in actual use, one or more metering columns 10 may be provided on the bottom wall. In an embodiment of the present invention, one metering column 10 is provided, but how to determine the volume of the metering column 10 and the volume of the detergent dispenser to ensure accurate dosage depends on the specific situation. In an embodiment of the present invention, the metering column 10 can indicate the dosage on the one hand, and on the other hand, it can also force the user or prompt the user to use only dishwashing powder in this first chamber 4, and not detergent blocks, to prevent the user from mistakenly adding detergent blocks to the detergent dispenser, resulting in the detergent blocks not being fully dissolved.

[0054] Example 2

[0055] A dishwasher is also provided in an embodiment of the present invention. When using the dishwasher to wash tableware, after opening the door, the tableware to be washed is placed, and an appropriate amount of dishwashing powder is added to the first chamber 4, and rinse agent is added as needed. After closing the door and starting, the washing water starts to circulate under the drive of the motor, and the water sprayed out through the water channel near the door and the side wall of the inner tank falls into the open first chamber 4. The impact force of the water and the gravity of the dishwashing powder itself are used to make the dishwashing powder solvent melted in the water slide on the inclined bottom wall, pass through the liquid outlet 9, and slide into the inner tank, further merge with the washing water in the inner tank to form a detergent solution, and start the cleaning cycle.

[0056] The detergent dispenser is installed on the side wall of the inner tank of the dishwasher. During use, it will not be soaked by the dishwasher, nor will it seep water. In addition, the utilization rate of the internal space is improved. The decorative cover 14 of the detergent dispenser is provided with a dishwashing powder chamber and a rinse agent chamber on the rear side. When in use, the decorative cover 14 and the cover plate 2 are opened, and the corresponding additives are added to the different chambers respectively. Then the decorative cover 14 is closed. During the closing process, the side of the cover plate 2 close to the decorative cover 14 will gradually abut against the extended end of the tightening structure 3. When the decorative cover 14 is about to be completely closed, the force of the tightening structure 3 to close the cover plate 2 is the greatest. When the cover plate 2 is completely closed, the switch buckle will also clamp the cover plate 2, completely covering the cover plate 2. Finally, the decorative cover 14 switch buckle can be closed.

[0057] In this embodiment of the present invention, when opening the cover 2 to add brightener, the cover 2 tilts at an angle less than 90°, remaining open. The angle between the decorative cover 14 and the radial plane of the housing 1 is 45°. This 45° outward protrusion is ergonomically designed, making brightener addition more convenient when the cover 2 is open, allowing direct observation of the liquid level inside and facilitating control of the amount added.

[0058] During use, washing water enters through the water inlet, and enters the first chamber 4 through the water inlet channel and the water injection hole. The dishwashing powder in the first chamber 4 is washed and dissolved by the washing water and flows out along the liquid outlet 9. The liquid outlet 9 is located on the bottom wall of the first chamber 4 to facilitate the outflow of dishwashing powder. The second chamber 5 is located next to the first chamber 4. The structure is compact and the space is used reasonably. You only need to open the rinse agent cover 2 to load the rinse agent in, which is convenient for adding. The rinse agent injection port is set obliquely downward. The injection port near the decorative cover 14 is the highest, and the injection port away from the decorative cover 14 is the lowest, which is convenient for adding rinse agent and is also to cooperate with the tightening structure 3 to prevent the rinse agent from leaking.

[0059] A brightener outlet 17 is further provided at the bottom of the second chamber 5. The brightener outlet 17 is connected to the second chamber 5 through a conduit. A solenoid valve cooperating with the conduit is provided on the housing 1. When the solenoid valve is not energized, the valve core of the solenoid valve tightly abuts 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 the second chamber 5 is discharged from the brightener outlet 17 through the conduit. By controlling the solenoid valve, the opening and closing of the conduit can be controlled, thereby controlling the dosage time and dosage of the brightener.

[0060] Since water is constantly sprayed out of the water channel and dishwashing powder is very soluble in water, especially the inclined design of the bottom wall, the concave arc surface further strengthens the design and increases the contact time and dissolution space between the dishwashing powder and water, so that the dishwashing powder in the first chamber 4 can quickly dissolve into the inner pot to form a detergent solution, participating in the cleaning process without leaving any residue on the bottom wall.

[0061] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments using the above technical content without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
