Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of laundry treating equipment, and particularly relates to an additive feeding device of a washing machine, and further relates to a washing machine provided with the additive feeding device. BACKGROUND

[0002] The existing washing machine is generally provided with a water containing cylinder for containing washing water, and a rotatable washing cylinder is arranged in the water containing cylinder. A dehydration hole is formed in the washing cylinder to communicate the inside and outside of the washing cylinder, so that the washing water flowing into the water containing cylinder can flow in and out of the washing cylinder through the dehydration hole, so as to realize the effect that the washing water contacts with the load to be treated arranged in the washing cylinder and the load is treated by the washing water.

[0003] The additive feeding mode of the above-mentioned existing washing machine is as follows: the additive feeding device feeds the additive into the pipeline communicated with the water containing cylinder of the washing machine, and then the fed additive flows into the water containing cylinder of the washing machine along the pipeline. Therefore, the additive fed by the existing mode is in the water containing cylinder of the washing machine and outside the washing cylinder, and cannot directly contact with the load arranged in the washing cylinder.

[0004] Then, when the washing machine performs the washing program, the fed additive is mixed with the washing water flowing into the water containing cylinder, and part of the washing water mixed with the additive flows into the washing cylinder through the dehydration hole and contacts with the load to be treated in the cylinder, so that a small part of the additive mixed in the washing water contacts with the load and produces an effect on the load. Therefore, the conventional additive feeding mode has the problems of low use efficiency of the fed additive and waste of the additive.

[0005] Meanwhile, in the conventional additive feeding mode, in order to ensure that the additive fed between the water containing cylinder and the washing cylinder contacts with the load to be treated in the washing cylinder, a large amount of water needs to flow into the water containing cylinder, and only after the water level of the washing water in the water containing cylinder is higher than that of the washing cylinder, the washing water can flow into the washing cylinder through the dehydration hole, and the additive can contact with the load in the washing cylinder. Therefore, the conventional additive feeding mode also has the problem of excessive water for feeding the additive.

[0006] In addition, the existing additive feeding device is generally provided with a shell constituting a water box, and the water box is connected in series with the water inlet pipe of the washing machine. After the additive to be fed flows into the water box through the water channel, the additive to be fed in the water box is flushed out when the water of the washing machine flows through the water box, and the flushed additive to be fed flows into the water containing cylinder of the washing machine together with the water of the washing machine and is outside the washing cylinder, so as to realize the purpose of feeding the additive.

[0007] However, the additive feeding device with the above-mentioned structure has the following problems:

[0008] 1. The additive needs to flow through the water box for dispensing, which increases the dispensing path of the additive, resulting in more additive residue in the dispensing path and a decrease in the actual amount dispensed.

[0009] 2. The additive flows through the water box and into the water container. Because the cross-section of the water box is larger than that of the water channel, the flow rate of the water flowing through the water box will be slower, which may cause the water flow to fail to rinse the additive in time and leave residues in the water box.

[0010] In view of this, the present invention is hereby proposed. Summary of the Invention

Figure 9

[0069] In the embodiment, the distribution of each rib 14 in the water supply channel 1 can adopt any form, for example, as shown in FIG. 3, a plurality of ribs 14 are arranged at intervals along the flow direction of the water supply channel 1, and each rib 14 is distributed in a different cross section of the water supply channel 1 to block the mixture at different positions, thereby achieving the remarkable technical progress of multiple uniform treatment of the mixture at different nodes and further improving the uniformity of the mixture of the additive and water. At the same time, the interval distance between each rib 14 is greater than the width of the rib 14, so that the adjacent ribs 14 do not interfere with each other, thereby improving the agitation effect of the rib 14 on the mixture. Figure 9 Preferably, as shown in FIG. 4, in the embodiment, the cross-sectional area of each rib 14 towards the upstream side of the water supply channel 1 is greater than the cross-sectional area of each rib 14 towards the downstream side of the water supply channel 1, so as to increase the interception area of the rib 14 on the mixture, thereby improving the agitation effect of the rib 14 on the mixture.

[0107] This invention, by incorporating the aforementioned additive dispensing device 100 into a washing machine, allows the additive to flow directly from the water supply channel 1 to the nozzle 500 and then directly into the washing drum 300. This bypasses the water tank and the external water container 200 of the washing drum 300, allowing the additive to flow directly into the washing drum 300 and be sprayed onto the load to be treated. This achieves the goal of directly spraying the additive solution onto the load inside the washing drum 300. Furthermore, this design allows the washing machine equipped with the additive dispensing device 100 to directly spray the additive solution formed by mixing the additive with a small amount of incoming water in the water supply channel 1 onto the load inside the washing drum 300, thereby significantly improving the utilization rate of the dispensed additive.

[0108] like Figures 6 to 8 As shown, in this embodiment, a suction port 13 is provided in the middle of the water supply channel 1.

[0109] like Figure 6 As shown, in this embodiment, the portion of the water supply path 1 downstream of the suction port 13 can mix the additive flowing into the water supply path 1 with the incoming water to form an additive solution. Preferably, the suction port 13 is located close to the inlet 12 of the water supply path 1 to maximize the length of the water supply path 1 downstream of the suction port 13, thereby increasing the space in the downstream portion of the water supply path 1 where the additive and water are mixed, and thus improving the mixing uniformity between the additive and the incoming water.

[0110] In this embodiment, the nozzle 500 may be disposed on the housing, and / or door, and / or water tank 200, and / or window gasket 400 of the washing machine.

The opening of the washing drum 300 is connected to one end of the aforementioned channel. The washing machine casing has a clothes inlet that is connected to the other end of the aforementioned channel. A door is installed on the washing machine casing that can be opened and closed accordingly. When the door is closed, a closed space is formed inside the water tank 200. There is a gap between the door and the window gasket 400, and the gap directly connects the opening of the washing drum 300 to the washing drum 300. The nozzle 500 is internally connected; it is installed on the top of the window pad 400 and passes through the window pad 400. The part of the nozzle 500 on the inner periphery of the window pad 400 has a spray outlet, and the part on the outer periphery of the window pad 400 has an inlet. The nozzle 500 has a flow channel inside, and the two ends of the flow channel are connected to the inlet and the spray outlet, respectively. The spray outlet is set towards the opening of the washing drum 300, so that the additive solution sprayed from the nozzle 500 can be directly sprayed into the washing drum 300. This represents a significant technological advancement in achieving direct spraying of additives onto the load to be treated inside the washing drum 300 and improving the efficiency of additive dispensing.

[0113] In this embodiment, the nozzle 500 can be any existing spray structure, and the spray outlet can be configured as a plurality of spray holes arranged at intervals or as a single opening.
