[0001] The present invention relates to a washing machine, which includes a laundry treatment
compartment, a treatment agent distributing apparatus for distributing a treatment
agent to the laundry treatment compartment, and a treatment agent transfer channel
in fluid connection with the treatment agent distributing apparatus and the laundry
treatment compartment.
[0002] Patent application publication
DE102009030290A1 discloses a washing machine according to the preamble of claim 1.
[0003] Patent application publication
CN105463783 discloses a washing machine comprising a treatment agent distributing apparatus which
allows both automatic and manual treatment agent supply.
[0004] The patent application No.
CN102741472A discloses a laundry treatment agent automatic dosing system for a washing machine.
The automatic dosing system includes one manual dosing compartment and two storage
compartments. The two storage compartments are each provided with a sinking pump.
A treatment agent in the storage compartment is pumped out by using the sinking pump
and then enters an output pipe. To flush a treatment agent in the manual dosing compartment
or the output pipe into a laundry treatment drum, a water supply line separately supplies
water to the manual dosing compartment or the output pipe.
[0005] A disadvantage of the automatic dosing system is: Usually, water from a water supply
line can be input into only either the manual dosing compartment or the output pipe
according to a program setting. Therefore, a setting of the water supply line is bound
to be relatively complex. For example, one water passage is configured for each of
the manual dosing compartment and the output pipe, and one water valve is configured
for each water passage. Alternatively, the water supply line is provided with a water
passage switching mechanism. Disposed in such a manner, the automatic dosing system
has not only a complex structure but also relatively high costs. In addition, because
the top of the output pipe is covered by a cover, it is inconvenient for cleaning,
and a health hazard is easily caused after long-term use.
[0006] An objective of the present invention is to overcome or reduce the foregoing disadvantage
in the prior art, thereby simplifying a laundry treatment agent automatic dosing system,
and facilitating cleaning of the laundry treatment agent automatic dosing system.
[0007] For the foregoing objective, the present invention provides a washing machine according
to claim 1.
[0008] Because an automatically dosed treatment agent and a manually added treatment agent
are both added to the manual adding compartment before entering the treatment compartment,
the water supply channel needs only one outlet in communication with the manual adding
compartment. Therefore, a structure is simple, and costs are saved. In addition, the
manual adding compartment is open, and therefore is convenient for cleaning.
[0009] Preferably, triggering and a quantity of distributed agents of the distributing apparatus
are controlled by the control apparatus.
[0010] According to the invention, the treatment agent distributing apparatus includes two
storage compartments, which respectively store a detergent and a softener, and each
storage compartment is provided with the distributing apparatus. The two distributing
apparatuses can sequentially output the detergent and the softener to the manual adding
compartment according to control of the control apparatus.
[0011] To control water supply, the water supply channel is provided with a water valve
controlled by the control apparatus. After either of the two distributing apparatuses
outputs the detergent or the softener to the manual adding compartment, the control
apparatus opens the water valve, so that water flows to the manual adding compartment
through the water supply channel and is mixed with the detergent or the softener in
the manual adding compartment, and the mixture is flushed into the laundry treatment
compartment through the treatment agent transfer channel.
[0012] Preferably, the control apparatus is provided with multiple treatment programs, and
the distributing apparatus is controlled according to a treatment program selected
by a user.
[0013] Preferably, the manual adding compartment is disposed adjacent to the storage compartment.
Therefore, it is convenient to output the treatment agent to the manual adding compartment
by the distributing apparatus.
[0014] Further, the treatment agent distributing apparatus includes a first storage compartment
and a second storage compartment, which are respectively are located on two sides
of the manual adding compartment or are disposed by at least partially surrounding
the manual adding compartment.
[0015] The present invention is further described below with reference to the accompanying
drawings.
- FIG. 1
- is a schematic plan view of a treatment agent distributing apparatus; and
- FIG. 2
- is a schematic diagram of connections of partial means of a washing machine.
[0016] As shown in FIG. 1 and FIG. 2, a washing machine has a laundry treatment compartment
2, and a treatment agent distributing apparatus 4 for distributing a treatment agent
to the laundry treatment compartment 2 is in fluid connection with the laundry treatment
compartment 2 through a treatment agent transfer channel 6. A water supply channel
8 is in fluid connection with the treatment agent distributing apparatus 4, to supply
water to the treatment agent distributing apparatus 4, so that a treatment agent added
to the treatment agent distributing apparatus 4 is flushed into the treatment compartment
2 through the transfer channel 6.
[0017] The treatment agent distributing apparatus 4 has a first storage compartment 41 for
storing a detergent, a second storage compartment 42 for storing a softener, and a
manual adding compartment 43 into which a treatment agent is manually added. The first
storage compartment 41 and the second storage compartment 42 are disposed adjacent
to the manual adding compartment 43, and surround two sides and a rear side of the
manual adding compartment 43. A front side refers to a side close to a direction in
which a user approaches. The top of the first storage compartment 41 and the top of
the second storage compartment 42 are covered by a cover 40 and are respectively provided
with a first treatment agent adding opening 44 and a second treatment agent adding
opening 45 through which treatment agents available for use of multiple times are
added. The manual adding compartment 43 is open at the top.
[0018] An outlet 46 is provided at the bottom of the manual adding compartment 43 and is
in communication with the treatment agent transfer channel 6. A first distributing
apparatus 47 is disposed in the first storage compartment 41, and a second distributing
apparatus 48 is disposed in the second storage compartment 42. The first distributing
apparatus 47 and the second distributing apparatus 48 are pumps. An outlet 470 of
the first distributing apparatus 47 and an outlet 480 of the second distributing apparatus
48 are both in fluid connection with the manual adding compartment 43. Therefore,
a detergent extracted from the first distributing apparatus 47 and a softener extracted
from the second distributing apparatus 48 both flow into the manual adding compartment
43.
[0019] To supply the treatment agent in the manual adding compartment 43 into the treatment
compartment 2, the water supply channel 8 is in fluid connection with the manual adding
compartment 43. To control water supply, the water supply channel 8 is provided with
a water valve 81.
[0020] The first distributing apparatus 47, the second distributing apparatus 48, and the
water valve 81 are all controlled by a control apparatus 10.
[0021] The control apparatus 10 is provided with multiple treatment programs. For different
programs, settings of whether to automatically pour a treatment agent from the first
storage compartment 41 and the second storage compartment 42, and settings of a quantity
of treatment agents are different. In addition, whether to automatically pour the
treatment agent is further controlled by the user. The user may set in advance whether
to automatically pour the treatment agent. A quantity of treatment agents that are
automatically poured is also different due to a material and a quantity of laundry.
The control apparatus 10 controls triggering and quantities of distributed agents
of the first distributing apparatus 47 and the second distributing apparatus 48.
[0022] If a treatment program selected by the user is by default not automatically pouring
the treatment agent, or the user sets a treatment program to not automatically pouring
the treatment agent, the user manually adds a detergent to the manual adding compartment
43 before washing is started. After the program starts running, the control apparatus
10 opens the water valve 81. The water supply channel 8 supplies water to the manual
adding compartment 43. The detergent in the manual adding compartment 43 is flushed
into the treatment compartment by the water, and the program enters a main washing
stage. After the main washing stage ends, the program pauses, and prompts the user
to put a softener in. After the user puts the softener into the manual adding compartment
43, the program enters a rinsing stage and an eventual water extracting stage, and
finally, the program ends.
[0023] If a treatment program selected by the user is by default automatically pouring the
treatment agent, or the user sets a treatment program to automatically pouring the
treatment agent, after the program starts, the control apparatus 10 triggers the first
distributing apparatus 47 to supply a detergent to the manual adding compartment 43,
and then the control apparatus 10 opens the water valve 81. The water supply channel
8 supplies water to the manual adding compartment 43. The detergent in the manual
adding compartment 43 is flushed into the treatment compartment 2 by the water, and
the program enters a main washing stage. After the main washing stage ends, the control
apparatus 10 triggers the second distributing apparatus 48 to supply a detergent to
the manual adding compartment 43, and then the control apparatus 10 opens the water
valve 81. The water supply channel 8 supplies water to the manual adding compartment
43. A softener in the manual adding compartment 43 is flushed into the treatment compartment
2 by the water, and the program enters a rinsing stage.

drawings are only used for illustrating the present invention, and are not considered
as the entirety of the present invention. Within the scope of the claims, any types
of modifications for the present invention can be made by persons ordinarily skilled
