Description

Technical Field

[0001] This utility model relates to the field of washing machine dispensing assembly design technology, specifically to a dispensing assembly and a washing machine. Background Technology

[0002] A top-loading washing machine is a type of washing machine that uses an electric motor to drive a pulsator, causing clothes to tumble continuously in the water. It comes in single-tub, double-tub, and twin-tub configurations. Its structure is relatively simple, easy to maintain, and has a high washing efficiency, but it causes greater wear and tear on clothes and uses more water. With technological advancements, newer, computer-controlled washing machines have emerged, employing large or concave pulsators. Their advantages include less tangling of clothes, more even washing, and lower damage to garments. The washing tub body is available in four main materials: all-plastic, enamel, aluminum alloy, and stainless steel. The working principle of a top-loading washing machine: The pulsator at the bottom of the tub rotates in both directions, causing the clothes to tumble continuously, creating gentle friction between the clothes and against the tub walls in the water. The detergent then helps to remove dirt and clean the clothes.

[0003] In the existing technology, most washing machines use a pull-out liquid storage box, where laundry detergent and fabric softener are added to the corresponding liquid storage box before washing, so as to realize the automatic dispensing of laundry detergent and fabric softener during the washing process.

[0004] However, pull-out liquid collection boxes have a large motion envelope. If the liquid collection box for laundry detergent or fabric softener is placed above the washing chamber of a top-loading washing machine, it will take up a lot of space and affect the space utilization. Utility Model Content

[0005] This application provides a dispensing assembly and a washing machine, which can solve the problem that the existing pull-out liquid storage box has a large motion envelope. If the liquid storage box for laundry detergent or fabric softener is placed above the washing chamber of a pulsator washing machine, it will occupy a large space and affect the space utilization rate.

[0006] In a first aspect, embodiments of this application provide a delivery assembly, which includes:

[0007] A water channel plate has a water channel and at least one liquid storage chamber inside, the liquid storage chamber being connected to the water channel, and the water channel being used to connect to the inner drum of a washing machine.

[0008] The tipping mechanism is rotatably connected to the side of the water circuit plate near the central axis of the inner drum of the washing machine, and the tipping direction is towards the central axis of the inner drum of the washing machine. The tipping mechanism is provided with a number of liquid inlets corresponding to the liquid storage chamber, and the liquid inlets are connected to the liquid storage chamber one by one.

[0009] In one embodiment, the system further includes a pushing mechanism and a locking mechanism. The pushing mechanism is connected to the tipping mechanism and is used to provide a pushing force that causes the tipping mechanism to tip over. The locking mechanism is disposed on the tipping mechanism and is used to connect to the water channel plate so that the tipping mechanism is stationary relative to the water channel plate when it is in an untilted state.

[0010] In one embodiment, the ejection mechanism includes a fixing member and a torsion spring. The torsion spring is disposed at one end of the tipping mechanism, and the fixing member is connected to the tipping mechanism to fix the torsion spring on the tipping mechanism.

[0011] In one embodiment, a damping mechanism is further included, which is disposed at the end of the tipping mechanism away from the ejection mechanism, and the damping direction is opposite to the tipping direction of the tipping mechanism.

[0012] In one embodiment, the locking mechanism is a horn switch.

[0013] In one embodiment, the water channel plate includes:

[0014] The water channel plate body has the water channel inside, and the water channel plate body is rotatably connected to the tipping bucket mechanism;

[0015] An extension plate corresponding to each of the liquid storage chambers, wherein the liquid storage chambers are provided within the extension plate.

[0016] In one embodiment, the water channel plate is provided with two liquid storage chambers, and the two extension plates are located on both sides of the tipping mechanism and are arranged along the edge of the inner drum of the washing machine.

[0017] In one embodiment, the end of the extension plate is provided with a connecting bend, and the liquid storage chamber is connected to the corresponding liquid inlet through the connecting bend.

[0018] In one embodiment, each of the liquid storage chambers is equipped with a liquid level sensor.

[0019] Secondly, embodiments of this application also provide a washing machine, which includes the aforementioned dispensing assembly.

[0020] The beneficial effects of the technical solutions provided in this application include:

[0021] In designing this dispensing assembly, the water channel plate includes a water channel and at least one liquid storage chamber. The liquid storage chamber is connected to the water channel, which is used to connect to the inner drum of the washing machine. The tipping mechanism is rotatably connected to the side of the water channel plate closest to the central axis of the inner drum, and the tipping direction faces the central axis of the inner drum. The tipping mechanism has a number of dispensing ports corresponding to the liquid storage chambers, and each dispensing port is connected to a liquid storage chamber. Because the tipping mechanism is rotatably connected to the side of the water channel plate closest to the central axis of the inner drum, and the tipping direction faces the central axis of the inner drum, and because the tipping mechanism only needs to tip over without being pulled out, the motion envelope is small, saving space. This solves the problem of the large motion envelope of pull-out liquid storage boxes in existing technologies. If the liquid storage box for laundry detergent or fabric softener is placed above the washing chamber of a pulsator washing machine, it will occupy a large amount of space, affecting the space utilization rate.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0033] This application provides a dispensing assembly and a washing machine, which can solve the problem that the existing pull-out liquid storage box has a large motion envelope. If the liquid storage box for laundry detergent or fabric softener is placed above the washing chamber of a pulsator washing machine, it will occupy a large space and affect the space utilization rate.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, in one aspect, this application provides a delivery assembly, which includes:

[0035] Water circuit board 1, which has a water circuit 12 and at least one liquid storage chamber 11, the liquid storage chamber 11 is connected to the water circuit 12, and the water circuit 12 is used to connect to the inner drum of the washing machine.

[0036] The tipping mechanism 2 is rotatably connected to the side of the water circuit plate 1 near the central axis of the inner drum of the washing machine, and the tipping direction is towards the central axis of the inner drum of the washing machine. The tipping mechanism 2 is provided with a number of liquid inlets 21 corresponding to the liquid storage chamber 11, and the liquid inlets 21 are connected to the liquid storage chamber 11 one by one.

[0037] In designing this dispensing assembly, the water channel plate 1 includes a water channel 12 and at least one liquid storage chamber 11. The liquid storage chamber 11 is connected to the water channel 12, which is used to connect to the inner drum of the washing machine. The tipping mechanism 2 is rotatably connected to the side of the water channel plate 1 closest to the central axis of the inner drum of the washing machine, and the tipping direction faces the central axis of the inner drum. The tipping mechanism 2 has a number of dispensing ports 21 corresponding to the number of liquid storage chambers 11, and the dispensing ports 21 are connected to the liquid storage chambers 11 one by one. Since the tipping mechanism 2 is rotatably connected to the side of the water channel plate 1 closest to the central axis of the inner drum of the washing machine, and the tipping direction faces the central axis of the inner drum, and the tipping mechanism 2 only needs to tip over without being pulled out, the motion envelope is small, saving space. This solves the problem that the motion envelope of the pull-out liquid storage box in the prior art is large. If the liquid storage box for laundry detergent or fabric softener is placed above the washing chamber of a pulsator washing machine, it will occupy a large space and affect the space utilization rate.

[0038] like Figure 3 As shown, in this example, it also includes a water inlet valve 6, a piston pump 7, a nozzle 9, and an impeller 10. The water inlet valve 6 is located on one side of the water circuit plate 1 and is connected to the water circuit 12 for water inlet. The piston pump 7 is located inside the water circuit 12 to direct the water mixed with fabric softener and laundry detergent within the water circuit 12. The impeller 10 is located inside the water circuit 12 for fully mixing fabric softener and water or laundry detergent and water. The nozzle 9 is connected to the outlet of the water circuit 12 and faces the inner drum of the washing machine for spraying the water mixed with fabric softener and laundry detergent into the inner drum of the washing machine.

[0039] like Figure 3 As shown, in this example, a pipe clamp 20 is provided on the side of the liquid inlet 21 that enters the water circuit board 1 to reduce the risk of leakage or breakage.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, in some optional embodiments, a pushing mechanism 3 and a locking mechanism 5 are also included. The pushing mechanism 3 is connected to the tipping mechanism 2 and is used to provide a pushing force to flip the tipping mechanism 2. The locking mechanism 5 is disposed on the tipping mechanism 2 and is used to connect to the water channel plate 1 so that the tipping mechanism 2 is stationary relative to the water channel plate 1 when it is in the unflipped state.

[0041] In this embodiment, the dispensing assembly also includes a pushing mechanism 3 and a locking mechanism 5. The pushing mechanism 3 is connected to the tipping mechanism 2 and is used to provide a pushing force to make the tipping mechanism 2 flip. The locking mechanism 5 is disposed on the tipping mechanism 2 and is used to connect to the water channel plate 1 so that the tipping mechanism 2 is relatively stationary with respect to the water channel plate 1 when it is not flipped. When the tipping mechanism 2 is not flipped, the locking mechanism 5 is connected to the water channel plate 1, and the locking force of the locking mechanism 5 resists the pushing force of the pushing mechanism 3, so that the tipping mechanism 2 is relatively stationary with respect to the water channel plate 1. When the locking mechanism 5 is unlocked, the locking mechanism 5 is separated from the water channel plate 1, and the tipping mechanism 2 flips under the action of the pushing force of the pushing mechanism 3, which is convenient for use.

[0042] like Figure 4 and Figure 5 As shown, in some optional embodiments, the ejection mechanism 3 includes a fixing member 31 and a torsion spring 32. The torsion spring 32 is disposed at one end of the tipping mechanism 2, and the fixing member 31 is connected to the tipping mechanism 2 to fix the torsion spring 32 on the tipping mechanism 2.

[0043] In this embodiment, the specific structure of the ejection mechanism 3 is described in detail. The ejection mechanism 3 includes a fixing member 31 and a torsion spring 32. The torsion spring 32 is disposed at one end of the tipping mechanism 2 along its length. The fixing member 31 is connected to the tipping mechanism 2 and is used to fix the torsion spring 32 on the tipping mechanism 2. The torsion spring 32 provides the ejection force to make the tipping mechanism 2 flip. The structure is simple and easy to replace after damage.

[0044] like Figure 3 , Figure 6 and Figure 7 As shown, in some optional embodiments, a damping mechanism 4 is also included. The damping mechanism 4 is disposed at the end of the tipping mechanism 2 away from the ejection mechanism 3, and the damping direction is opposite to the flipping direction of the tipping mechanism 2.

[0045] In this embodiment, the dispensing assembly also includes a damping mechanism 4. The damping mechanism 4 is located at the end of the tipping mechanism 2 away from the ejection mechanism 3, and the damping direction is opposite to the flipping direction of the tipping mechanism 2. It provides a buffering effect to prevent the tipping mechanism 2 from being damaged due to excessive collision force when it quickly pops out to the maximum flipping position, thereby improving the stability of the dispensing assembly.

[0046] In this example, damping mechanism 4 is a common rotary damper.

[0047] like Figure 3 and Figure 8 As shown, in some optional embodiments, the locking mechanism 5 is a horn switch.

[0048] In this embodiment, the locking mechanism 5 is a horn switch. After the locking tongue is pressed for the first time, the locking mechanism 5 is connected to the water circuit board 1. After pressing it again, the locking mechanism 5 is released. The structure is simple and easy to use.

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, in some optional embodiments, the water channel plate 1 includes:

[0050] The water channel plate body 13 has a water channel 12 inside it, and the water channel plate body 13 is rotatably connected to the tipping bucket mechanism 2.

[0051] An extension plate 14 is provided in each of the liquid storage chambers 11.

[0052] In this embodiment, the specific structure of the water channel plate 1 is described. The water channel plate 1 includes a water channel plate body 13 and an extension plate 14. The water channel plate body 13 is provided with a water channel 12. The water channel plate body 13 is rotatably connected to the tipping mechanism 2. The extension plate 14 corresponds one-to-one with the liquid storage chamber 11, and the liquid storage chamber 11 is set in the extension plate 14. The structure is simple and the capacity of the liquid storage chamber 11 is increased.

[0053] like Figure 2 and Figure 3 As shown, in this example, the water circuit board body 13 includes a lower water circuit board base plate 131, a water circuit board housing 132, and a water circuit board upper cover 133. The extension plate 14 includes a lower extension plate housing 141 and an upper extension plate housing 142, which facilitates installation. The upper extension plate housing 142 is provided with a vent valve 143 to facilitate balancing the air pressure inside and outside the liquid storage chamber 11.

[0054] like Figure 2 and Figure 3 As shown, in some optional embodiments, the water channel plate 1 is provided with two liquid storage chambers 11, and two extension plates 14 are located on both sides of the tipping mechanism 2 and are arranged along the edge of the inner drum of the washing machine.

[0055] In this embodiment, the water channel plate 1 is provided with two liquid storage chambers 11, and two extension plates 14 are located on both sides of the tipping mechanism 2 and are arranged along the edge of the inner drum of the washing machine. The two liquid storage chambers 11 are used to store laundry detergent and fabric softener respectively. The two extension plates 14 are located on both sides of the tipping mechanism 2 and are arranged along the edge of the inner drum of the washing machine, which can reduce the space occupied above the inner drum of the washing machine and further improve the space utilization rate.

[0056] like Figure 2 and Figure 3 As shown, in some optional embodiments, the end of the extension plate 14 is provided with a connecting bend 15, and the liquid storage chamber 11 is connected to the corresponding liquid inlet 21 through the connecting bend 15.

[0057] In this embodiment, a connecting bend 15 is provided at the end of the extension plate 14. The liquid storage chamber 11 is connected to the corresponding liquid inlet 21 through the connecting bend 15. The structure is simple and the overall weight is reduced, which is beneficial to the lightweighting of the device.

[0058] like Figure 3 As shown, in some optional embodiments, a liquid level sensor 8 is provided in the liquid storage chamber 11.

[0059] In this embodiment, each liquid storage chamber 11 is equipped with a liquid level sensor 8 to facilitate the acquisition of the liquid volume in the liquid storage chamber 11, so as to obtain the time for adding liquid.

[0060] like Figure 1 , Figure 2 and Figure 3 As shown, on the other hand, this application also provides a washing machine that includes the aforementioned dispensing assembly.

[0061] In designing this dispensing assembly, the water channel plate 1 includes a water channel 12 and at least one liquid storage chamber 11. The liquid storage chamber 11 is connected to the water channel 12, which is used to connect to the inner drum of the washing machine. The tipping mechanism 2 is rotatably connected to the side of the water channel plate 1 closest to the central axis of the inner drum of the washing machine, and the tipping direction faces the central axis of the inner drum. The tipping mechanism 2 has a number of dispensing ports 21 corresponding to the number of liquid storage chambers 11, and the dispensing ports 21 are connected to the liquid storage chambers 11 one by one. Since the tipping mechanism 2 is rotatably connected to the side of the water channel plate 1 closest to the central axis of the inner drum of the washing machine, and the tipping direction faces the central axis of the inner drum, and the tipping mechanism 2 only needs to tip over without being pulled out, the motion envelope is small, saving space. This solves the problem that the motion envelope of the pull-out liquid storage box in the prior art is large. If the liquid storage box for laundry detergent or fabric softener is placed above the washing chamber of a pulsator washing machine, it will occupy a large space and affect the space utilization rate.
