Detailed Description
The technical solution provided by the present invention will be further explained with reference to the specific embodiments and the accompanying drawings. The advantages and features of the present invention will become more apparent in conjunction with the following description.
Fig. 1 is a schematic structural diagram of a household appliance 100 according to an embodiment of the present invention, and fig. 2 is a schematic structural diagram of a water distribution device 110, a water inlet passage 120, a first water outlet passage 130, and a second water outlet passage 140 according to an embodiment of the present invention. The household appliance 100 comprises a water dispensing device 110 having a housing 112, and a water inlet passage 120, a first water outlet passage 130 and a second water outlet passage 140 connected to the housing 112. The housing 112 includes a top portion, a bottom portion, and side portions, wherein the top portion is the highest portion of the housing 112, the bottom portion is the lowest portion of the housing 112 (where water flow may accumulate), and the side portions extend between the top and bottom portions.
A first end of the inlet passage 120 may be coupled to the water valve assembly 150 to receive inlet water, and the water valve assembly 150 may provide water at different flow rates to the water dispensing apparatus 110; although fig. 1 illustrates the water valve assembly 150, the first end of the water inlet passage 120 in the present disclosure is not limited to being connected to the water valve assembly 150, and may be directly connected to an external water source that provides water at different flow rates. A second end of the water inlet passage 120 is connected to the water inlet 114 on the housing 112 to provide inlet water to the water dispensing device 110. At different operating stages of the household appliance 100, it may be necessary to provide water flows of different flow rates to meet different water requirements in terms of flow rate, etc. in a plurality of areas within the household appliance 100; the different flow rates of water include a first flow having a higher flow rate and a second flow having a lower flow rate (the higher flow rate and the lower flow rate are relative to each other and are respectively applied to areas of the household appliance having different requirements for flow rates, for example, the higher flow rate of water is used in a cleaning scene such as washing in the household appliance, and the lower flow rate of water is used in a cooling isothermal control scene in the household appliance), in the water distribution device 110, the first flow of water flows from the water inlet 114 to the first water outlet 116, and the second flow of water flows from the water inlet 114 to the second water outlet 118; it should be understood that in the technical solution of the present invention, the water flows with different flow rates are not limited to the two water flows (i.e. the first water flow and the second water flow) but include more than two (e.g. three, four or more) flow rates.
A first end of the first water outlet channel 130 is connected to the first water outlet 116 on the housing 112, and the first end of the first water outlet channel 130 or the first water outlet 116 is disposed opposite to the water inlet 114 to receive the first water flow having a higher flow rate from the water inlet 114. Wherein the "opposite" arrangement of the first end of the first water outlet channel 130 and the water inlet 114 means that both are arranged in the flow direction of the first water flow and such that the former can substantially receive the water flow from the latter, for example 80%, 90%, 95%, or 100% of the water flow from the latter. The second end of the first outlet channel 130 is connected to a water usage area of the household appliance requiring a larger flow and/or a higher flow rate.
The height of the first water outlet 116 may be higher, equal to, or lower than the height of the water inlet 114. In case the height of the first water outlet 116 is higher than, equal to, the height of the water inlet 114, the positions of the water inlet channel 120, the water inlet 114 and the first water outlet 116 may be arranged such that the first water flow in the water dispensing device 110 is inclined upwards with respect to the horizontal direction, such that the first end of the first water outlet channel 130 may substantially receive the water flow from the water inlet 114. In case the first water outlet 116 is lower than the height of the water inlet 114, the position of the water inlet channel 120, the water inlet 114 and the first water outlet 116 may be arranged such that the first water flow in the water dispensing device 110 is inclined downwards with respect to the horizontal direction, such that the first end of the first water outlet channel 130 may substantially receive the water flow from the water inlet 114. In a specific embodiment, as shown in fig. 2, an inclination angle α of a connection line between the first water outlet 116 and the water inlet 114 with respect to the horizontal direction may be set in a range of minus 30 degrees to 30 degrees, wherein 30 degrees means 30 degrees clockwise rotation from an imaginary line located in the horizontal direction in fig. 2, and minus 30 degrees means 30 degrees counterclockwise rotation from the imaginary line.
The top of the housing 112 may extend between the water inlet 114 and the first water outlet 116 and be adapted to direct a first flow of water from the water inlet 114 to the first water outlet 116. In a specific embodiment, as shown in fig. 2, the inclination angle α of the top with respect to the horizontal direction may be set in the range of minus 30 degrees to 30 degrees, where 30 degrees means 30 degrees clockwise from the imaginary line located in the horizontal direction in fig. 2, and minus 30 degrees means 30 degrees counterclockwise from the imaginary line.
A first end of the second water outlet channel 140 is connected to the second water outlet 118 on the housing 112, and the first end of the second water outlet channel 140 or the second water outlet 118 is arranged to have a height lower than that of the water inlet 114 to receive the second water flow with a lower flow rate from the water inlet 114; in particular implementations, the second water outlet 118 may be disposed near or at the bottom of the housing 112, for example, the second water outlet 118 may be located at a distance from zero to 1/2 of the length of the side of the housing relative to the bottom of the housing. The second end of the second outlet channel 140 is connected to a water usage area of the household appliance requiring a smaller flow and/or a lower flow rate.
The second water flow can flow from the water inlet 114 to the bottom of the housing 112 (i.e. the bottom space of the cavity formed by the housing 112) along the side where the water inlet 114 is located, or can be ejected from the water inlet 114 for a distance, and then the second water flow cannot reach the first water outlet 116 due to its low flow velocity, and falls to the bottom of the housing 112 under the action of gravity.
In embodiments of the invention, different flow rates of the water source may be distributed and output as desired. Specifically, for the first water flow having a higher flow rate, the first end of the first water outlet channel 130 and the water inlet 114 are oppositely disposed so that the former can substantially receive the flow of water from the latter. In one embodiment, the cross-sectional area of the first end of the first outlet channel is greater than the cross-sectional area of the water inlet, such that the first end of the first outlet channel 130 is able to receive more water flow from the water inlet 114 when in operation. For the second water flow with a lower flow rate, the first end of the second water outlet channel 140 or the second water outlet 118 is set to have a height lower than that of the water inlet 114 to receive the second water flow with a lower flow rate from the water inlet 114, and the second water flow is accumulated at the bottom of the housing 112 (i.e. accumulated in the bottom space of the cavity formed by the housing 112), and the accumulated amount of the second water flow at the bottom of the housing 112 is determined according to the amount of water used in the corresponding area of the household appliance 100. In one embodiment, the cross-sectional area of the first end of the second outlet channel is less than the cross-sectional area of the inlet 114, such that in operation the second flow of water from the inlet 114 is not completely discharged from the second outlet 118, accumulating at the bottom of the housing 112; in another embodiment, second outlet channel 140 is arranged in a curved arrangement near its first end, i.e., in a non-linear shape having an arc (e.g., a V-arc or a U-arc), a fold, or an angle, such as V-arc 145 shown in FIG. 2, so that in operation, the second flow of water from inlet 114 is not completely discharged through curved second outlet channel 140, and thus accumulates at the bottom of housing 112.
In some embodiments of the present invention, the household appliance 100 comprises a third water outlet channel, the first end of which is connected to a third water outlet on the housing 112 and is disposed at a height lower than the height of the water inlet 114 to receive a third water flow with a lower flow rate from the water inlet and to enable the third water flow to accumulate at the bottom of the housing 112 (i.e., in the bottom space of the cavity formed by the housing 112). The third water flow may be the second water flow, in which case the second end of the third water outlet channel is connected to a water usage area of the household appliance requiring a smaller flow and/or a lower flow rate (which is different from the water usage area to which the second end of the second water outlet channel is connected), thereby enabling the utilization of the second water flow by the two water usage areas; the third water flow may also be another water flow than the second water flow, in which case the second end of the third water outlet channel is connected to a water usage area of the household appliance that requires a specific flow and/or a specific flow rate of the third water flow.
In particular implementations, the third water outlet may be located near or at the bottom of the housing 112, for example, at a distance from zero to 1/2 of the length of the side of the housing relative to the bottom of the housing.
In one embodiment, the cross-sectional area of the first end of the third outlet channel is less than the cross-sectional area of the inlet 114, such that the third flow of water from the inlet 114 is not completely discharged from the third outlet during operation, and thus accumulates at the bottom of the housing 112; in another embodiment, the third outlet channel is arranged in a curved arrangement near the first end thereof, i.e., in a non-linear shape having an arc (e.g., a V-arc or a U-arc), a fold, or an angle, such that in operation the third flow of water from the inlet 114 does not completely exit through the curved third outlet channel, thereby accumulating at the bottom of the housing 112.
Further, the household appliance 100 may provide more water outlet channels connected to the housing 112 to provide the first water flow and/or the second water flow, respectively, or to provide water flows with different speeds from the first water flow and the second water flow, so as to realize multiple requirements of different areas of the household appliance 100 for water flows.
In some embodiments of the present invention, the household appliance 100 is a laundry device 200, and the following description is made in conjunction with a partial structure of the laundry device 200 shown in fig. 3. In fig. 1, 2, and 3, although reference numerals of some components are different, the same component names are used because of having similar or identical positional relationships, connection relationships, functions, and the like.

The valve part 250 includes a flush valve and a cooling valve having a common valve inlet for receiving a water flow from outside the laundry device 200 and a valve outlet connected to the first end of the water inlet passage 220, the laundry device 200 being adapted to provide a first water flow having a higher flow rate for flushing the flushing area when the flush valve is open and the cooling valve is closed and a second water flow having a lower flow rate for cooling the cooling area when the cooling valve is open and the flush valve is closed.
The second end of the water inlet channel 220 is connected to a water inlet in the housing of the water dispensing device 210 to convey the flow of water from the valve member 250 into the water dispensing device 210.
The first water outlet passage 230 has a first end connected to a first water outlet on the housing of the water dispensing device 210 and a second end connected to a rinsing area of the laundry device 200. In one embodiment, the cross-sectional area of the first end of the first outlet channel 230 is greater than the cross-sectional area of the water inlet, such that the first end of the first outlet channel 230 is able to receive more water flow from the water inlet when in operation. In the embodiment shown in fig. 3, the flushing area includes a fan 260 and a fan inlet area 265.
The first end of the second water outlet channel 240 is connected to the second water outlet on the housing of the water dispensing device 210 and is arranged at a height lower than the height of the water inlet to receive the second water flow with a lower flow rate from the water inlet and to allow the second water flow to accumulate at the bottom of the housing (i.e. in the bottom space of the cavity formed by the housing); the second end is connected to a first cooling area of the laundry device 200 (e.g., a first condenser in the outer tub 280, and the second outlet passage 240 passes through the outer tub 280 to reach the first condenser). In one embodiment, the first end of the second outlet channel 240 has a cross-sectional area that is smaller than the cross-sectional area of the inlet port, such that in operation the second flow of water from the inlet port does not completely exit the second outlet port, accumulating at the bottom of the housing; in another embodiment, the second outlet channel 240 is arranged in a curved arrangement near the first end, i.e. in a non-linear shape such as an arc (e.g. a V-arc or a U-arc), a broken line or an angle, such as the arc 245 shown in fig. 3, so that in operation the second flow of water from the inlet does not completely exit through the curved second outlet channel 240 and thus accumulates at the bottom of the housing.
In some embodiments of the present invention, the laundry device 200 comprises a third water outlet channel 270 having a first end connected to a third water outlet on the housing of the water dispensing device 210 and disposed at a height lower than the water inlet to receive a second water flow having a lower flow rate from the water inlet and to allow the second water flow to accumulate at the bottom of the housing (i.e., in the bottom space of the cavity formed by the housing); the second end is connected to a second cooling region (e.g., a second condenser in the outer tub 280, and the third outlet passage 270 passes through the outer tub 280 to reach the second condenser) of the laundry device 200. In one embodiment, the first end of the third outlet channel 270 has a cross-sectional area that is smaller than the cross-sectional area of the inlet port, such that in operation the second flow of water from the inlet port does not completely exit the second outlet port, accumulating at the bottom of the housing; in another embodiment, third outlet channel 270 is arranged in a curved arrangement near its first end, i.e., in a non-linear shape having an arc (e.g., a V-arc or a U-arc), a fold, or an angle, such as arc 275 shown in FIG. 3, so that in operation the second flow of water from the inlet does not completely exit through curved third outlet channel 270 and thus accumulates at the bottom of the housing.
As shown in fig. 3, an inclination angle α (at reference numeral 215) of a connection line between the first water outlet and the water inlet with respect to the horizontal direction may be set in a range of minus 30 degrees to 30 degrees, wherein 30 degrees means 30 degrees clockwise from a dotted line located in the horizontal direction in fig. 3, and minus 30 degrees means 30 degrees counterclockwise from the dotted line.
Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
