Description

Technical Field

[0001] This application relates to the field of washing machine technology, and in particular to a washing machine dispensing premixing device. Background Technology

[0002] In the existing technology, the detergents used in washing machines mainly include laundry powder, laundry liquid, and fabric softener. In automatic washing machines, the detergent is usually added by the user into the dispenser, and then the machine automatically operates to put the detergent into the washing drum. This method of dispensing causes the detergent to clump together when it falls into the washing drum, and it often fails to dissolve fully in the early stages of the washing machine's operation. In particular, granular laundry powder is directly flushed into the washing drum by the water flow after being added to the dispenser, resulting in low solubility.

[0003] Therefore, the current structural design of washing machines cannot fully utilize the washing effect of detergents. Utility Model Content

[0042] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solution of this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0043] This embodiment provides a premixing device for a washing machine, such as... Figure 1 , Figure 2 As shown, it includes: device body 1, detergent dispensing box 2, and stirring component 3.

[0044] like Figure 2 , Figure 3 As shown, the main body 1 of the device has a premixing tank 12, an outlet 13, and a water-separating rib 14. The water-separating rib 14 is located inside the premixing tank 12, dividing the premixing tank 12 into a first area 121 and a second area 122. The second area 122 is connected to the outlet 13. The outlet 13 is used to connect to the washing drum (the area for washing clothes) of the washing machine, that is, the premixed detergent is discharged into the washing drum from the outlet 13.

[0045] like Figure 4 As shown, the detergent dispensing box 2 is installed on the main body 1 of the device; the function of the detergent dispensing box 2 is to allow the user to dispense detergent. The detergents mentioned in this embodiment include, but are not limited to, laundry powder, laundry liquid and fabric softener and other clothing treatment agents.

[0046] like Figure 3 As shown, the agitator 3 is installed in the first region 121 to agitate the water flow in the first region 121.

[0047] The washing machine premixing device provided in this embodiment is used as follows: Before starting the washing machine, the user adds detergent to the detergent dispenser 2. After the washing machine starts, the detergent in the detergent dispenser 2 is discharged into the first zone 121. Water is supplied to the first zone 121, and as the agitator 3 is activated, the detergent is fully agitated and dissolved in the water. Water is then further introduced into the first zone 121. As the water overflows the baffle 14, the fully dissolved detergent-containing water flows into the second zone 122, and then from the second zone 122 into the outlet 13. The outlet 13 is connected to the washing drum of the washing machine. Therefore, the detergent-containing water premixed in this premixing device is finally dispensed into the washing area of ​​the washing machine.

[0048] The washing machine premixing device provided in this embodiment, such as Figures 1-6 As shown, the detergent in the detergent dispenser 2 can be discharged into the first zone 121. The first zone 121 is separated from the second zone 122 by the water-separating rib 14. Therefore, after water is introduced into the first zone 121, the detergent can be fully dissolved in the water by the stirring member 3. After the stirring member 3 has fully stirred the detergent, water is continued to be added to the water inlet 22 so that the water in the first zone 121 with fully dissolved detergent overflows the water-separating rib 14 and enters the second zone 122, and then is discharged into the outlet 13 and enters the washing drum. Therefore, the washing machine dispensing premixing device provided in this embodiment improves the detergent's dissolving ability, which is beneficial for the detergent to fully exert its washing effect in the automatic washing machine.

[0049] In an alternative embodiment, such as Figure 2 As shown, the detergent dispenser 2 includes a detergent dispensing tank 21, a water inlet 22, and a drain outlet 23; the detergent dispensing tank 21 is for holding detergent, and the water inlet 22 is connected to the detergent dispensing tank 21, supplying water flow into the detergent dispensing tank 21, such as... Figure 5 , Figure 6 As shown, the detergent dispensing tank 21 is connected to the first area 121 via the drain outlet 23. The detergent in the detergent dispensing tank 21 can be flushed into the first area 121 through the drain outlet 23 by the water flow. In this embodiment, by providing the detergent dispensing tank 21, it is convenient for the laundry powder or liquid detergent manually added by the user to be carried to the first area 121 by the water flow.

[0050] In an alternative embodiment, such as Figure 3As shown, the washing machine premixing device provided in this embodiment also includes a siphon tube 4, with a first end opening and a second end opening at both ends. The first end opening communicates with the first region 121 and is located at the bottom of the first region 121, while the second end opening communicates with the second region 122. The highest point of the siphon tube 4 in the vertical direction is lower than the top of the water-blocking rib 14. In this embodiment, by arranging the siphon tube 4, water in the first region 121 with a water level lower than that of the water-blocking rib 14 can be transferred to the second region 122 using the siphon effect, and then discharged from the outlet 13. This helps to empty the premixing tank 12 as much as possible and reduce detergent residue.

[0051] In an alternative embodiment, such as Figure 7 As shown, the first region 121 includes a premixing tank body 1211 and a recessed region 1212. The lowest point of the recessed region 1212 in the vertical direction is lower than the lowest point of the premixing tank body 1211 in the vertical direction. In this embodiment, by setting a region with a relatively low height, the water flow in the premixing tank 12 is collected so that it can be drawn out by the siphon pipe 4, which is beneficial to fully empty the premixing tank 12.

[0052] In an alternative embodiment, such as Figure 7 As shown, the agitator 3 is installed in the recessed area 1212. In this embodiment, by arranging the agitator 3 in the recessed area 1212, the water at lower water levels is prevented from being insufficiently agitated.

[0053] In an alternative embodiment, such as Figure 7 As shown, in this embodiment, the stirring component 3 is a pulsator-shaped component, which can cause the still water to form a vortex when it rotates, thus promoting the dissolution of detergent.

[0054] In an optional embodiment, the washing machine premixing device further includes a drive component disposed outside the premixing tank 12. The drive component can magnetically drive the stirring component 3 to move. In this embodiment, the stirring component 3 adopts a non-contact design with the drive component. The rotating parts of both the stirring component 3 and the drive component are magnets (including permanent magnets, electromagnets, and combinations thereof). Through mutual magnetic force, the drive component can transmit power to the stirring component 3 from outside the premixing tank 12, causing the stirring component 3 to move. This embodiment eliminates the need for additional openings in the premixing tank 12, reducing the manufacturing cost of the main body 1 of the device.

[0055] In an alternative embodiment, such as Figure 8As shown, the washing machine's premixing device also includes a limiting cover 6, which covers the outside to restrict the movement range of the agitator 3. In this embodiment, by setting the limiting cover 6, the agitator 3 can be prevented from having an excessive range of movement in the premixing tank 12, especially from exceeding the connection range of the drive component, ensuring that it can be driven normally. It is understood that in order not to affect the basic function of the agitator 3 (stirring water), the limiting cover 6 should have the following characteristics: Figure 8 The portion shown is hollowed out.

[0056] In an alternative embodiment, such as Figure 8 As shown, the limiting cover 6 has buckles 61 on both sides, and the limiting cover 6 is detachably fastened to the wall of the premixing tank 12 by means of the buckles 61. In this embodiment, the limiting cover 6 is designed as a detachable structure, which facilitates the installation or maintenance and replacement of the stirring component 3.

[0057] In an optional embodiment, the washing machine's premixing device further includes a driving component, which comprises a main body and a driving end capable of rotating relative to the main body. The main body of the driving component is disposed outside the premixing tank 12, and one side of the premixing tank 12 has a through hole. The driving end of the driving component passes through the through hole and connects to the stirring component 3. In this embodiment, the through hole on one side of the premixing tank 12 is used to allow the driving end of the driving component to pass through and connect to the stirring component 3, thereby realizing the transmission of the stirring component 3. It is understood that the through hole needs to be properly sealed to prevent water leakage. This embodiment has low structural requirements for the driving component and does not require the installation of a limiting cover 6.

[0058] In an alternative embodiment, such as Figure 5 , Figure 6 As shown, the washing machine's premixing device also includes an automatic dispensing box 7, which dispenses laundry detergent or fabric softener. The water flow path in the detergent dispensing tank 21 surrounds the automatic dispensing box 7. In this embodiment, arranging the detergent dispensing tank 21 around the automatic dispensing box 7 makes the premixing device more compact. Furthermore, the non-linear structure of the detergent dispensing tank 21 prevents water from rapidly flowing out of the drain outlet 23 after entering the tank, thus avoiding a decrease in detergent carrying capacity. On the other hand, since laundry detergent is generally added by the user on an ad-hoc basis, the layout of the detergent dispensing tank 21 in this embodiment allows it to be positioned slightly closer to the front of the washing machine for easy user dispensing, while the automatic dispensing box 7 is positioned towards the rear.

[0059] In an alternative embodiment, such as Figure 5 As shown, the automatic dispensing box 7 includes a first compartment 71 and a second compartment 72 arranged side by side. In this embodiment, the automatic dispensing box 7 is divided into two compartments so that one can hold laundry detergent and the other can hold fabric softener when in use. Understandably, more compartments can be provided as needed.

[0060] In an optional embodiment, the automatic dispensing box 7 stores laundry detergent or fabric softener, which is automatically drawn out when the washing machine starts. The drawn detergent or fabric softener is directly discharged into the first zone 121. In this case, the water supply to the first zone 121 can be a separate water supply line, or it can be directly supplied from the detergent dispensing box 2. That is, after water enters through the water inlet 22, the water flows through the detergent dispensing tank 21 and is discharged from the drain outlet 23 into the first zone 121. In this scheme, the automatic dispensing box 7 and the detergent dispensing box 2 share the same water inlet 22.

[0061] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this application that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of this application and do not limit the scope of protection of this patent application.
