Description

Technical Field

[0001] The present invention belongs to the technical field of washing machines, and particularly relates to a detergent dispensing structure and a washing machine having the same. Background Art

[0002] Conventional agitator washing machines usually add detergents manually. Due to the instability of manual detergent addition, there may be too much or too little added. When too much detergent is added, it will cause waste, and when too little is added, the clothes may not be washed clean. Therefore, according to market demand, there are also washing machines that can achieve quantitative detergent dispensing. However, when such washing machines achieve quantitative detergent dispensing, they often need to add electrical components such as a dispensing pump or a dispensing valve, rather than using a simple mechanical structure, resulting in a relatively large increase in cost. Summary of the Invention

[0003] Therefore, the present invention provides a detergent dispensing structure, which can overcome the deficiency that existing washing machines need to add electrical components such as a dispensing pump or a dispensing valve when achieving quantitative detergent dispensing, resulting in a relatively large increase in cost.

When the water supply component supplies water, the water flow in the water supply component can enter the independent accommodation cavity through the water inlet to mix with the detergent and can enter the laundry space through the water outlet. When the water supply component does not supply water, the two one-way components can respectively block the water inlet and the water outlet.

[0009] In some embodiments, the one-way component is a rubber flap.

[0010] In some embodiments, the water supply component includes a water pipe and a water inlet valve. The water pipe is communicated with the water inlet, and the water inlet valve is arranged on the inflow path of the water pipe.

[0033] Referring to Figures 1 to 11 As shown, according to the embodiment of the present invention, a detergent dispensing structure is provided, including: a cover base 1 and a door cover assembly 2 disposed thereon. The door cover assembly 2 includes a door cover 21. The cover base 1 has a laundry inlet, and the door cover 21 has a closed position capable of closing the laundry inlet and an open position communicating with the laundry inlet. It further includes a detergent metering device 3, and the detergent metering device 3 includes a storage box 31 and a transfer box 32. When the door cover 21 is in the open position, the detergent in the storage box 31 can enter the transfer box 32. When the door cover 21 is in the closed position, the detergent in the transfer box 32 can enter the laundry space. In this technical solution, when washing clothes, during the process of opening the door cover 21 to put the clothes into the washing machine through the laundry inlet, the detergent in the storage box 31 will enter the transfer box 32. After the door cover 21 is closed, the detergent in the transfer box 32 can be quantitatively fed into the laundry space, that is, the quantitative dispensing of the detergent is realized by the opening and closing of the door cover 21. Compared with realizing the quantitative dispensing of the detergent by adding electrical components such as a dispensing pump or a dispensing valve, the present invention adopts simple mechanical control, which is not only simple to operate but also can significantly reduce costs.

[0034] As a specific implementation manner, the door cover assembly 2 further includes a sliding control assembly. The sliding control assembly is at least partially located in the transfer box 32. The sliding control assembly includes a sliding body capable of sliding relative to the transfer box 32. An independent accommodation cavity is formed on the sliding body. The sliding body can reciprocally slide in the transfer box 32 following the position switching of the door cover 21. The storage box 31 has an outlet communicating with the transfer box 32. When the door cover 21 is in the closed position, the sliding body can block the outlet. During the process of the door cover 21 switching from the open position to the closed position, the independent accommodation cavity can communicate with the storage box 31 through the outlet.

[0035] In this embodiment, the sliding body is located within the transfer box 32 and is capable of sliding relative to the transfer box 32. When the door cover 21 is in the closed position, the outlet of the storage box 31 is blocked by the sliding body, so the detergent in the storage box 31 will not enter the transfer box 32. When the door cover 21 is opened, the door cover 21 will control the sliding body to slide within the transfer box 32. During the sliding process, the sliding body will gradually unblock the outlet of the storage box 31 and connect the outlet of the storage box 31 with the independent accommodation cavity. During this process, the detergent in the storage box 31 will also continuously enter the independent accommodation cavity. When the door cover 21 is opened to the maximum extent, the outlet of the storage box 31 will be completely connected to the independent accommodation cavity. At this time, the detergent has completely filled the entire independent accommodation cavity. Even if the door cover 21 remains in the open state, the detergent will no longer enter the independent accommodation cavity, thus realizing the quantitative function of the detergent quantitative dispensing device 3. After the door cover 21 is closed, the sliding body completely blocks the outlet of the storage box 31, and the detergent in the independent accommodation cavity enters the laundry space, finally realizing the quantitative dispensing of the detergent by the detergent quantitative dispensing device 3 after the opening and closing of the door cover 21. To ensure that the detergent can completely fill the independent accommodation cavity, each time try to open the door cover 21 to the maximum extent.

[0036] Specifically, the sliding body includes two blocking bodies 22 and a connecting body 23. The two blocking bodies 22 are connected by the connecting body 23 and are arranged in sequence along the sliding direction of the sliding body. The two blocking bodies 22 and a part of the inner wall of the transfer box 32 jointly enclose an independent accommodation cavity.

[0037] In this embodiment, since the two blocking bodies 22 match the transfer box 32, when the structure connecting the two blocking bodies 22 with the connecting body 23 is assembled into the transfer box 32, the two blocking bodies 22 will enclose an independent accommodation cavity with a fixed volume with a part of the inner wall of the transfer box 32, and the detergent entering the independent accommodation cavity will not leak out. Further, the formation of the independent accommodation cavity only borrows the two blocking bodies 22, which is equivalent to only needing two side walls to form a complete accommodation cavity, thus simplifying the structural design. The blocking body 22 has a certain width. When the door cover 21 is in the closed state, the top of the blocking body 22 close to the door cover 21 completely blocks the outlet of the storage box 31, so that when the door cover 21 is in the closed position, the detergent in the storage box 31 will no longer enter the independent accommodation cavity.

[0038] As a specific implementation manner, sealing rings 4 are sleeved on both of the two blocking bodies 22.

[0039] In this embodiment, sleeving the sealing rings 4 on the blocking bodies 22 can further prevent the detergent from leaking out around the blocking bodies 22.

[0040] As a specific implementation manner, the detergent metering and dispensing device 3 further includes a water supply component. The transfer box 32 has a water inlet and a water outlet, and one-way components are provided at both the water inlet and the water outlet. When the water supply component supplies water, the water flow in the water supply component can enter the independent accommodation cavity through the water inlet to mix with the detergent and can enter the laundry space from the water outlet. When the water supply component does not supply water, the two one-way components can respectively block the water inlet and the water outlet.

[0041] In this embodiment, when the independent accommodation cavity is filled with detergent and the door cover 21 is in the closed position, the water supply component starts to supply water. Then the water flow will rush towards the water inlet of the transfer box 32. Under the action of water pressure, the one-way component at the water inlet of the transfer box 32 is flushed open, and the water flow enters the independent accommodation cavity to mix with the detergent. At this time, the one-way component at the water outlet of the transfer box 32 will also open under the dual pressure of the water flow and the detergent. Then the detergent will flow out mixed in the water flow. Eventually, the detergent in the independent accommodation cavity will be gradually and completely flushed into the laundry space by the water flow, thus realizing that after the door cover 21 is closed, the detergent metering and dispensing device 3 quantitatively dispenses the detergent into the laundry space of the washing machine. When the water supply component does not supply water, the two one-way components always block the water inlet and the water outlet, which ensures that the detergent will not automatically leak out from the water inlet or the water outlet of the transfer box 32, and also ensures that no matter how many times the door cover 21 is opened or closed during the laundry process, the detergent will not enter the laundry space from the independent accommodation cavity.

[0042] As a specific implementation manner, the one-way component is a rubber flap 5.

[0043] In this embodiment, since the rubber flap 5 has sufficient elasticity, when the water supply component does not supply water, the two rubber flaps 5 always block the water inlet and the water outlet of the transfer box 32 under the action of their own elastic forces, and the pressure generated by the detergent cannot flush open the rubber flap 5. When the water supply component supplies water, the water pressure generates a certain thrust on the rubber flap 5, causing the two rubber flaps 5 to respectively conduct the water inlet and the water outlet, realizing the dispensing of the detergent. After the water supply ends, the rubber flap 5 automatically resets under the action of its own elastic force and blocks the water inlet and the water outlet again, so that no matter how many times the door cover 21 is opened or closed when the water supply component does not supply water, the detergent will not be dispensed into the laundry space.

[0044] As a specific implementation manner, the water supply component includes a water pipe 34 and a water inlet valve 35. The water pipe 34 is communicated with the water inlet, and the water inlet valve 35 is arranged on the inflow path of the water pipe 34.

[0045] In this embodiment, the water inlet valve 35 can be opened for flow or cut off for flow. The setting of the water inlet valve 35 realizes the one-way flow of the water flow.

[0046] As a specific implementation manner, the water inlet is close to the top of the transfer box 32; and / or, the water outlet is close to the bottom of the transfer box 32.

[0047] In this embodiment, as Figure 11 shown, at the water inlet, the detergent will exert an outward pressure on the rubber flap 5, and this pressure is opposite to the water pressure. The lower the water inlet is, the greater the pressure of the detergent on the rubber flap 5 at the water inlet. Therefore, on the premise of not hindering installation, the water inlet should be as close as possible to the top of the transfer box 32 so that the water flow can immediately wash open the rubber flap 5. Before the water flow enters the independent accommodation cavity, the rubber flap 5 at the water outlet is mainly subjected to the outward pressure from the detergent. After the water flow enters, the rubber flap 5 at the water outlet will be subjected to the double outward pressures from the detergent and the water flow. When the water outlet is closer to the bottom of the transfer box 32, the double pressure is greater, and the rubber flap 5 at the water outlet is also more easily washed open. At the same time, the water outlet being close to the bottom of the transfer box 32 is also beneficial for the detergent to be completely washed out.

[0048] As a specific implementation manner, the detergent metering and dispensing device 3 further includes a dispensing box 33. The transfer box 32 is nested in the dispensing box 33, and the independent accommodation cavity is connected to the dispensing box 33 through the water outlet, and the dispensing box 33 is connected to the laundry space.

[0049] In this embodiment, the water inlet of the transfer box 32 penetrates through the side wall of the dispensing box 33 and is connected to the water pipe 34. The dispensing box 33 has a dispensing port. After being drained by the dispensing box 33, the mixture of water and detergent in the independent accommodation cavity enters the laundry space through the dispensing port.

[0050] As a specific implementation manner, the transfer box 32 and the dispensing box 33 share part of the side wall.

[0051] In this embodiment, as Figure 11 shown, one side wall and the top wall of the transfer box 32 completely borrow the side wall and the top wall of the dispensing box 33, which can save materials.

[0052] As a specific implementation manner, the sliding control assembly further includes a transmission mechanism, and the door cover 21 and the sliding body are connected through the transmission mechanism.

[0053] In this embodiment, the door cover 21 controls the sliding body through the transmission mechanism. When the independent accommodation cavity is filled with detergent and then the door cover 21 is closed, the sliding of the sliding body in the transfer box 32 will be hindered by the detergent. Through the transmission of the transmission mechanism, the slow falling of the door cover 21 can be realized, thereby also realizing the damping effect of the detergent instead of the damping oil.

[0054] As a specific embodiment, the transmission mechanism includes a rotating shaft 24 of the door cover 21 and a rack 25 connected to the sliding body. The door cover 21 is rotatably connected to the cover base 1 through the rotating shaft 24, and the rotating shaft 24 can rotate following the position switching of the door cover 21. A tooth portion is provided on the outer circumferential wall of the rotating shaft 24, and the tooth portion meshes with the rack 25.

[0055] In this embodiment, when the door cover 21 is opened, the door cover 21 will rotate clockwise on the cover base 1 through the rotating shaft 24. Through the meshing action between the tooth portion on the rotating shaft 24 and the rack 25, the clockwise rotating shaft 24 will drive the rack 25 to move forward. During the forward movement of the rack 25, it will drive the sliding body to move forward. During the forward movement of the sliding body, it will gradually connect the outlet of the storage box 31 with the independent accommodation cavity, as Figure 9 shown; when the door cover 21 is closed, the door cover 21 will rotate counterclockwise on the cover base 1 through the rotating shaft 24. Through the meshing action between the tooth portion and the rack 25, the counterclockwise rotating shaft 24 will drive the rack 25 to move backward. During the backward movement of the rack 25, it will drive the sliding body to move backward. During the backward movement of the sliding body, it will gradually block the outlet of the storage box 31 until the outlet of the storage box 31 is completely blocked, as Figure 7 shown. At the same time, since the door cover 21 can only be opened relative to the cover base 1 to about 95 degrees, the outer circumferential wall of the rotating shaft 24 does not need to be set in a full-tooth state, as long as the number of tooth bodies can meet the movement requirements of the sliding body.

[0056] As a specific embodiment, the storage box 31 further has an inlet. The cover base 1 has a rear shell, and an inlet is provided at the top of the rear shell. The storage box 31 is installed in the rear shell, and the inlet end is connected to the inlet.

[0057] In this embodiment, the storage box 31 is installed in the rear shell of the cover base 1, so that the storage box 31 is hidden, which not only plays a role in aesthetics but also protects the storage box 31. A flip cover 6 is provided at the inlet of the rear shell. When adding detergent to the storage box 31, just open the flip cover 6 for adding.

[0058] As a specific embodiment, the outlet is located at the bottom of the transfer box 32, and the transfer box 32 is located below the storage box 31.

[0059] In this embodiment, the transfer box 32 is arranged below the storage box 31, which is beneficial for the detergent in the storage box 31 to enter the transfer box 32 under the action of gravity.

[0060] According to an embodiment of the present invention, a washing machine is further provided, including the above-mentioned detergent dispensing structure. This washing machine can achieve quantitative dispensing of detergent by opening and closing the door cover 21.

[0061] Those skilled in the art can easily understand that, on the premise of no conflict, the above-mentioned advantageous ways can be freely combined and superimposed.

[0062] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention. The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
