Description

[0001] This application is a divisional application of the application "An additive dispensing device and washing machine"

[0002] Original application number: 2020108972863

[0003] Filing date of original application: August 31, 2020 Technical Field

[0004] The present invention belongs to the technical field of clothing processing equipment, and in particular relates to an additive dispensing device for a washing machine, and also relates to a washing machine equipped with the additive dispensing device. Background Art

[0005] Existing washing machines generally have a water drum for holding washing water, a rotatable washing drum is arranged in the water drum, and a dehydration hole is provided on the washing drum to connect the inside and the outside, so that the washing water flowing into the water drum can flow alternately inside and outside the washing drum through the dehydration hole, so as to achieve the effect of contacting the washing water with the load to be processed placed in the washing drum and using the washing water to process the load.

[0006] The aforementioned conventional washing machine additive dosing method involves injecting additives into a pipe connected to the washing machine's water drum via an additive dosing device. The additives then flow along the pipe into the washing machine's water drum. Consequently, the additives dispensed using this conventional method remain within the washing machine's water drum, outside the washing drum, and are unable to directly contact the load placed within the drum.

[0007] Then, when the washing machine performs a wash cycle, the added additive mixes with the wash water flowing into the water drum. Some of the wash water mixed with the additive flows through the dewatering hole into the washing drum and comes into contact with the load to be treated in the drum. Only then can a small portion of the additive mixed in the wash water come into contact with the load and take effect on the load. Therefore, the traditional method of adding additives has the problem of low efficiency of the added additives and waste of additives.

[0008] Furthermore, in conventional additive delivery methods, to ensure that the additives delivered between the water storage drum and the washing drum come into contact with the load being processed in the washing drum, a large amount of water must be flowed into the water storage drum until the water level in the water storage drum is higher than that in the washing drum. This ensures that the washing water flows into the washing drum through the dewatering holes and that the additives come into contact with the load in the washing drum. Therefore, conventional additive delivery methods still suffer from the problem of excessive water consumption.

[0009] In addition, the existing additive dispensing device generally has a shell forming a water box, which is serially connected to the water inlet pipe of the washing machine. After the additive to be dispensed flows into the water box through the water channel, the inlet water of the washing machine flows through the water box, flushing out the additive to be dispensed in the water box. The flushed additive to be dispensed flows into the water drum of the washing machine and outside the washing drum together with the inlet water, thereby achieving the purpose of dispensing the additive.

[0010] However, the additive dispensing device of the above structure has the following problems:

[0011] 1. The additives need to flow through the water box for delivery, which increases the delivery path of the additives, increases the residual amount of the additives in the delivery path, and reduces the actual delivery amount;

[0012] 2. The additives flow through the water box and into the water tank. Since the water box has a larger cross-section than the water channel, the flow rate of the water flowing through the water box will slow down, which may cause the water flow to fail to flush the additives in time and the additives to remain in the water box.

[0013] In view of this, the present invention is proposed. Summary of the Invention

[0065] In the embodiment of the present invention, the power unit may also be provided with other existing structures, for example: the power unit is a suction pump, the suction port of the suction pump is connected to the water supply channel 1, so that a negative pressure is formed in the water supply channel 1, and the additive in the liquid storage chamber 4 is pumped into the water supply channel 1 through the liquid pumping channel 8;

[0066] And / or, the power unit can also be a Venturi tube arranged on the water supply waterway 1, and the Venturi tube is provided with a negative pressure area with a sudden change in tube diameter.

[0068] In the embodiment of the present invention, the control device can be configured as any existing structure capable of achieving the above functions; for example:

[0069] In the embodiment of the present invention, each liquid storage chamber 4 can be connected to the water supply channel 1 via a flow channel provided with a control valve, so as to achieve the effect of on-off control of each flow channel separately or in combination by controlling the opening and closing of each control valve, thereby achieving the purpose of independently adding any type of additive or simultaneously adding multiple types of additives;

Preferably, the liquid suction port 13 is located near the inlet 12 of the water supply channel 1 to maximize the length of the water supply channel 1 downstream of the liquid suction port 13. This increases the space in the downstream portion of the water supply channel 1 where the additive and water mix, thereby improving the uniformity of mixing between the additive and the incoming water.
