Description

washing machine

【Technical field】

The present invention relates to a washing machine comprising a laundry treating chamber, a treating agent dispensing device for distributing treating agent to the laundry treating chamber, and a treating agent conveying channel fluidly connecting the treating agent dispensing device and the laundry treating chamber.

【Background technique】

The patent application publication with the publication number of CN102741472A discloses an automatic dosing system of a laundry treatment agent for a washing machine. The automatic dosing system consists of a manual dosing chamber and two storage chambers. The two storage chambers are respectively provided with immersion pumps. The treatment agent in the storage chamber is pumped out by the immersion pump and then enters the output pipe. In order to flush the treatment agent in the manual metering chamber or the output pipe into the laundry treatment tub, the clean water supply line supplies clean water to the manual metering chamber or the output pipe, respectively.

The disadvantage of this automatic dosing system is that the water in the clean water supply line can only be fed into the manual dosing chamber or the output pipe selectively according to the program settings, so the clean water supply line must have more complicated settings, such as manual dosing. Each of the measuring chamber and the output pipe is equipped with a water channel, and each water channel is equipped with a water valve, or a water channel switching mechanism is arranged on the clean water supply line. Such a setup is not only complicated but also costly. In addition, since the top of the output pipe is covered by the cover, it is not conducive to cleaning. Hygiene problems are likely to occur after long-term use.

[Content of the invention]

One object of the present invention is to overcome or reduce the above-mentioned defects in the prior art, simplify the automatic dosing system of laundry treatment agent, and make it easy to clean.

In view of the above objects, the present invention provides a washing machine, comprising a clothes treatment chamber, a treatment agent dispensing device for dispensing a treatment agent to the clothes treatment chamber, and a treatment agent delivery channel fluidly connecting the treatment agent dispensing device and the clothes treatment chamber, and the treatment agent is dispensed The device comprises at least one storage chamber for storing the treatment agent and a manual addition chamber for manually adding the treatment agent, wherein the manual addition chamber has an outlet at the bottom and communicates with the treatment agent delivery channel, the at least one storage chamber is provided with a controlled A device-controlled dispensing device, the outlet of the dispensing device is fluidly connected to the manual addition chamber, and the fresh water supply channel is fluidly connected to the manual addition chamber.

Since the automatically dosed treatment agent and the manually added treatment agent are added to the manual addition chamber before entering the treatment chamber, the clean water supply channel only needs an outlet that communicates with the manual addition chamber, so the structure is simple and the design and manufacturing costs are saved. Additionally, manual addition chambers tend to be open for easy cleaning.

Preferably, the triggering of the dispensing device and the dispensing dose are controlled by the control device.

Preferably, the treatment agent dispensing device comprises two storage chambers, respectively storing detergent and softener, and each storage chamber is provided with a dispensing device, respectively. The two dispensing devices can sequentially output detergent and softener to the manual addition chamber according to the control of the control device.

In order to control the supply of clean water, a water valve controlled by a control device is arranged on the clean water supply channel. After any one of the two dispensing devices outputs detergent or softener to the manual adding chamber, the control device opens the water valve, so that clean water flows to the manual adding chamber through the clean water supply channel, and the detergent or softener in it is mixed with clean water. Flush into the laundry treatment chamber through the treatment agent delivery channel.

Preferably, the control device is provided with various processing programs, and the dispensing device is controlled according to the processing program selected by the user.

Preferably, the manual addition chamber is positioned adjacent to the storage chamber, thus facilitating the dispensing device to output the treatment agent to the manual addition chamber.

Further, the treatment agent dispensing device includes a first storage chamber and a second storage chamber, which are respectively located on both sides of the manual addition chamber, or at least partially arranged around the manual addition chamber.

The present invention will be further described below with reference to the accompanying drawings.

【Description of drawings】

1 is a schematic plan view of a treatment agent dispensing device;

Fig. 2 is a schematic diagram showing the connection of some components of the washing machine.

【Detailed ways】

As shown in FIGS. 1 and 2 , the washing machine 1 has a laundry treatment chamber 2 , and a treatment agent dispensing device 4 for distributing a treatment agent to the clothes treatment chamber 2 is fluidly connected to the clothes treatment chamber 2 through a treatment agent delivery passage 6 . The clean water supply channel 8 is fluidly connected to the treatment agent dispensing device 4 , and supplies clean water to the treatment agent dispensing device 4 , so that the treatment agent added in the treatment agent dispensing device 4 is flushed into the treatment chamber 2 through the conveying channel 6 .

The treatment agent dispensing device 4 has a first storage chamber 41 for storing detergent, a second storage chamber 42 for storing softener, and a manual addition chamber 43 for manually adding a treatment agent. The first storage chamber 41 and the second storage chamber 42 are disposed adjacent to the manual addition chamber 43 and surround both sides and rear sides of the manual addition chamber 43 . The front side refers to the side close to the approaching direction of the user. The tops of the first storage chamber 41 and the second storage chamber 42 are covered by the cover 40, and are respectively provided with a first treatment agent addition port 44 and a second treatment agent addition port 45 for adding a treatment agent used for multiple times. The manual addition chamber 43 has an open top.

After the user puts the softener into the manual adding chamber 43, the program enters the rinsing stage and the final dehydration stage until the program ends.

If the treatment program selected by the user is preset to automatically inject the treatment agent, or the user sets it to automatically inject the treatment agent, after the program is started, the control device 10 triggers the first dispensing device 47 to supply the detergent into the manual adding chamber 43, and then controls the The device 10 opens the water valve 81 . The fresh water supply passage 8 supplies fresh water into the manual addition chamber 43 . The clean water flushes the detergent in the manual addition chamber 43 into the treatment chamber 2, and the program enters the main wash stage. After the main wash phase is over, the control device 10 triggers the second dispensing device 48 to supply detergent into the manual adding chamber 43 , and then the control device 10 opens the water valve 81 . The fresh water supply passage 8 supplies fresh water into the manual addition chamber 43 . The clean water flushes the softener in the manual addition chamber 43 into the treatment chamber 2, and the program enters the rinsing stage.

The various specific embodiments described above and shown in the accompanying drawings are only used to illustrate the present invention, but not all of the present invention. Within the scope of the basic technical idea of the present invention, any form of modification made by those of ordinary skill in the relevant technical field to the present invention is within the protection scope of the present invention.
