Either mechanically or electrically. Either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring to fig. 1, 8 and 9, a shunt valve assembly 10 according to an embodiment of the present invention can be applied to a household appliance 100 according to an embodiment of the present invention. In one example, the household appliance 100 may be a dishwasher or other household cleaning appliance that requires the use of a liquid (e.g., water).

The household appliance 100 includes a water distribution valve assembly 10, a chamber 20, a spray arm 30, and a heating device 40. Wherein a cavity 21 is formed in the cavity 20. The spray arm 30 is at least partially disposed within the chamber 21. The spray arm 30 is opened with a plurality of spray holes (not shown). Washing liquid can be sprayed into the chamber 21 via a plurality of spray holes to wash items (e.g., dishes) located within the chamber 21. In the example shown in fig. 1, the spray arm 30 includes a first spray arm 31, a second spray arm 32, and a third spray arm 33 that are arranged at intervals. The first spray arm 31, the second spray arm 32 and the third spray arm 33 may be an upper spray arm, a middle spray arm and a lower spray arm in sequence. The first spray arm 31, the second spray arm 32 and the third spray arm 33 may be used to wash items located at different positions within the chamber 21, respectively. The heating device 40 heats the washing water, and the heated washing water may be sprayed through the spray holes of the spray arm 30.

The shunt valve assembly 10 includes a housing 11 and a shunt valve 12. A water distribution chamber 111 is formed in the housing 11. The housing 11 is provided with a water inlet 112, a water return port 113, a first water outlet 114 and a second water outlet 115. The first water outlet 114 can be communicated with the water return port 113 through an external pipeline of the housing 11. The diversion valve 12 is disposed in the diversion chamber 111 and can divide the diversion chamber 111 into a first diversion chamber 1111 and a second diversion chamber 1112 that are partitioned. The first water dividing chamber 1111 is communicated with the water inlet 112. The water dividing valve 12 can rotate in the water dividing chamber 111 to make the first water dividing chamber 1111 communicate with the water inlet 112 and the first water outlet 114, make the second water dividing chamber 1112 communicate with the second water outlet 115 and the water return port 113, and make the water inlet 112 and the first water outlet 114 isolated and make the first water dividing chamber 1111 communicate with the water inlet 112 and the second water outlet 115.

It should be noted that the diverter valve assembly 10 is capable of achieving a first condition and a second condition described below when the diverter valve 12 is rotated within the diverter chamber 111. The first state and the second state are non-simultaneous states. Specifically, when the diversion valve 12 rotates to connect the first diversion chamber 1111 with the water inlet 112 and the first water outlet 114, the second diversion chamber 1112 can connect the second water outlet 115 with the water return port 113, that is, the first state of the diversion valve assembly 10 is realized, at this time, water flowing through the water inlet 112 can flow out from the first water outlet 114 through the first diversion chamber 1111, and water flowing out from the first water outlet 114 can flow into the second diversion chamber 1112 through the water return port 113 and flow out from the second water outlet 115 through the second diversion chamber 1112. When the household appliance 100 needs to be heated using the heating device 40, the shunt valve assembly 10 may be placed in the first state as described above, and the household appliance 100 may be considered to be in a heating mode. When the shunt valve 12 rotates to block the water inlet 112 from the first water outlet 114, the first shunt cavity 1111 communicates the water inlet 112 with the second water outlet 115, i.e. the second state of the shunt valve assembly 10 is achieved, and at this time, the water passing through the water inlet 112 can directly flow out from the second water outlet 115 through the first shunt cavity 1111. When the home appliance 100 does not need to be heated using the heating device 40, the shunt valve assembly 10 may be placed in the second state as described above, and the home appliance 100 may be considered to be in the non-heating mode.

In the present embodiment, the household appliance 100 further includes a water collection tank 50 and a washing pump 60. The washing liquid sprayed onto the washing items can be collected in a sump 50 at the bottom of the chamber 21. The bottom of the water collection tank 50 is provided with a washing outlet 201. The washing liquid flows out from the washing outlet 201. The inlet of the wash pump 60 is in communication with the wash outlet 201 and the outlet of the wash pump 60 is in communication with the water inlet 112 to provide power for circulation of the wash liquid through the wash pump 60. The heating device 40 is connected to the first water outlet 114 and the water return port 113 through a pipe.

Thus, when the water distribution valve assembly 10 is applied to the household appliance 100, the spray arm 30 can be connected to the second water outlet 115 through a pipeline, so that when water needs to be heated, the water distribution valve 12 can be rotated to enable the first water distribution chamber 1111 to be communicated with the water inlet 112 and the first water outlet 114, at this time, water entering through the water inlet 112 can flow out from the first water outlet 114 through the first water distribution chamber 1111 and be heated by the heating device 40, water heated by the heating device 40 can flow into the second water distribution chamber 1112 through the water return port 113 and can flow to the spray arm 30 through the second water outlet 115 for spraying, when water does not need to be heated, the water distribution valve 12 can be rotated to enable the water distribution valve 12 to block the water inlet 112 and the first water outlet 114, at this time, water entering through the water inlet 112 can directly flow from the second water outlet 115 to the spray arm 30 through the first water distribution chamber 1111 for spraying, so that water does not need to flow through, the resistance in the water flow system in the non-heating period can be reduced, the problems of the increase of power consumption of the washing pump 60 and the long washing time can be reduced, and the system washing performance of the household appliance 100 can be improved.

Of course, it is understood that the external pipe connecting the first water outlet 114 and the water return 113 may be provided with other devices (e.g., a plurality of heating devices), which may be set according to specific situations. In the example shown in fig. 1, the heating device 40 is a heat pump system including a compressor 41, a condenser 42, an expansion device 43, and an evaporator 44, and further, the compressor 41, the condenser 42, the expansion device 43, and the evaporator 44 are connected in this order by pipes to form a closed circulation system in which a refrigerant circulates.

It is understood that when the shunt valve 12 blocks the water inlet 112 and the first water outlet 114, the shunt valve 12 may also close the water return port 113 to block the second water outlet 115 from the water return port 113.

It should be noted that when the shunt valve 12 rotates in the shunt chamber 111, the spaces corresponding to the first shunt chamber 1111 and the second shunt chamber 1112 are changed. The pressure of the liquid entering the first water-dividing chamber 1111 from the water inlet 112 is greater than the pressure of the liquid entering the second water-dividing chamber 1112 from the water return 113 (due to pressure drop loss of the liquid flow). Thus, the first water-dividing chamber 1111 may be regarded as a high-pressure chamber, and the second water-dividing chamber 1112 may be regarded as a low-pressure chamber.

Referring to fig. 2 and 7, in some embodiments, the shunt valve 12 has a first blocking piece 121. The first shutter 121 is capable of opening or closing the first water outlet 114 when the shunt valve 12 is rotated. For example, in the example shown in fig. 2, the first stopper 121 is offset from the first water outlet 114 as the shunt valve 12 rotates to communicate the water inlet 112 with the first water outlet 114. As another example, in the example shown in fig. 7, the first flap 121 closes the first water outlet 114 to prevent liquid from entering the heating device 40 through the first water outlet 114. It is understood that the shape of the first blocking sheet 121 may be set according to specific situations, and may be, for example, a circular shape, an elliptical shape, or the like.

Referring to fig. 10 to 21, in some embodiments, the first blocking piece 121 is provided with a water through hole 1211, and when the diversion valve 12 rotates, the first blocking piece 121 can communicate the first water outlet 114 and the first diversion cavity 1111 through the water through hole 1211. Thus, when the water passage 1211 is not connected to the first water outlet 114, the first blocking piece 121 blocks the first water outlet 114 from the first water diversion chamber 1111. It is understood that the opening of the water passage hole 1211 may be set according to circumstances. The number of the water passage holes 1211 may be plural. For example, in the example shown in fig. 18, the water passage hole 1211 of the first blocking piece 121 does not communicate with the first water outlet 114 to close the first water outlet 114.

In certain embodiments, the shunt valve 12 has a separation flap 122. The partition blade 122 partitions the water diversion chamber 111 into a first water diversion chamber 1111 and a second water diversion chamber 1112. The separation blocking piece 122 can rotate in the water diversion cavity 111 to communicate the water inlet 112 with the first water outlet 114 or block the water inlet 112 from the first water outlet 114.

Specifically, when the separation blade 122 rotates in the diversion cavity 111 to communicate the water inlet 112 and the first water outlet 114, the diversion valve assembly 10 is in the first state. When the separation blade 122 rotates in the diversion cavity 111 to separate the water inlet 112 and the first water outlet 114, the diversion valve assembly 10 is in the second state.

It will be appreciated that the shape of the separation blade 122 may be configured as the case may be.

In some embodiments, the separation blade 122 includes a blade body 1221 and two blade tabs 1222 attached to both sides of the blade body 1221 (see fig. 14 and 15). Two baffle tabs 1222 are attached to the inner wall 1110 of the water distribution chamber 111. Flap tab 1222 abuts inner wall 1110 of diversion chamber 111 to seal the gap between flap tab 1222 and inner wall 1110 of diversion chamber 111 to ensure the diversion of diversion valve assembly 10.

It is understood that the flap body 1221 and the two flap tabs 1222 may be integrally formed or may be separately formed.

In some embodiments, the flap tab 1222 is arcuately coupled to the inner wall 1110 of the dispensing chamber 111. Thus, the sealing effect is better. Specifically, the first arc-shaped surface formed by the baffle connecting piece 1222 is attached to the second arc-shaped surface formed by the inner wall 1110 of the water diversion cavity 111.

In certain embodiments, the shunt valve 12 has a second stop 123. The second shutter 123 can open or close the second water outlet 115 when the shunt valve 12 rotates. Thus, the second water outlet 115 is opened or closed through the position change of the second blocking piece 123 along with the rotation of the shunt valve 12.

Specifically, when the diversion valve 12 rotates to open the second water outlet 115, the liquid in the diversion cavity 111 can flow out of the second water outlet 115 through the second blocking piece 123. When the diversion valve 12 rotates to close the second water outlet 115, the liquid in the diversion cavity 111 cannot flow out of the second water outlet 115 by the second blocking piece 123.

In some embodiments, the number of the second water outlets 115 is multiple, the number of the second blocking pieces 123 is multiple, and the number of the second blocking pieces 123 is the same as the number of the second water outlets 115. In this way, the positions of the plurality of second shutters 123 may be rotated to open or close different second water outlets 115.

In some examples (please refer to fig. 2, 4 to 7, and 9 to 18), the number of the second water outlets 115 is two. The number of the second stoppers 123 is two. The two second water outlets 115 are spaced apart. Two second shutters 123 are disposed at intervals.

In some examples, the number of the second water outlets is three. The number of the second baffle plates is three. The three second water outlets are distributed at intervals. The three second baffles are distributed at intervals. At this time, the number of the second water outlets of the shunt valve assembly 10 is the same as that of the spray arms 30 of the electric home appliance 100. The three second water outlets can be correspondingly connected with the first spray arm 31, the second spray arm 32 and the third spray arm 33 respectively so as to realize different application modes.

Of course, it is understood that the number of the second water outlets may also be 4 or 5, and the number of the second blocking pieces may also be 4 or 5, and the like, which is not limited herein.

Referring to fig. 2-7, in some embodiments, diverter valve 12 has a third flap 126. The third step 126 is capable of opening or closing the return port 113 when the shunt valve 12 is rotated.

For example, in the example shown in fig. 2, the third flap 126 opens the return port 113 to communicate the return port 113 with the two second water outlet ports 115. As another example, in the example shown in fig. 5, the third flap 126 closes the water return port 113 to achieve a better closing effect on the water return port 113.

Referring to fig. 2 to 7, the diversion valve 12 has a first blocking piece 121, two second blocking pieces 123 and a third blocking piece 126. A first baffle 121, two second baffles 123 and a third baffle 126 are distributed at intervals along the circumferential direction of the water diversion cavity 111. The partition blade 122 partitions the water diversion chamber 111 into a first water diversion chamber 1111 and a second water diversion chamber 1112.

Referring to fig. 8 to 22, the shunt valve 12 has a first blocking plate 121 and two second blocking plates 123. The top of the diverter valve 12 forms a first flap 121. The first stopper 121 has a water passage hole 1211. Two second flaps 123 are detachably mounted to the bottom (i.e., the fixing portion 124) of the shunt valve 12. Two second shutters 123 are disposed at intervals. The separation block piece 122 connects the first block piece 121 and the fixing portion 124. The partition blade 122 partitions the water diversion chamber 111 into a first water diversion chamber 1111 and a second water diversion chamber 1112.

In the example shown in FIG. 2, the diverter valve assembly 10 is in the first mode when the diverter valve 12 is rotated to the position shown in FIG. 2. The first blocking piece 121 opens the first water outlet 114 when the shunt valve 12 rotates. The two second blocking pieces 123 arranged at intervals are staggered with the two second water outlets (i.e. the second water outlet 115a and the second water outlet 115b) along with the rotation of the shunt valve 12, so that the second water outlet 115a and the second water outlet 115b are in an open state. The water inlet 112 and the first water outlet 114 are located at a side of the first water distribution chamber 1111, and the water return 113 and the two second water outlets are located at a side of the second water distribution chamber 1112. The third shutter 126 is staggered from the return port 113 as the shunt valve 12 rotates to open the return port 113.

The first water dividing chamber 1111 communicates with the water inlet 112 and the first water outlet 114, the first water outlet 114 communicates with the heating device 40, and the second water dividing chamber 1112 communicates with the two second water outlets and the water return port 113 at the same time. At this time, after the liquid enters from the water inlet 112, the liquid can flow out from the first water outlet 114 through the first water diversion chamber 1111, and after the liquid is heated by the heating device 40, the liquid can flow back to the second water diversion chamber 1112 through the water return port 113, and can flow out from the two second water outlets, and the flowing direction of the liquid is shown by arrows in fig. 2. So that the shunt valve assembly 10 can supply water through the two second water outlets simultaneously. For example, when the shunt valve assembly 10 is applied to the electric home appliance 100, one of the two second water outlets 115a may communicate with the third spray arm 33, and the other second water outlet 115b may communicate with the first spray arm 31 and the second spray arm 32. Thus, when the two second water outlets are opened simultaneously, the three spray arms of the household appliance 100 can spray the heated water simultaneously.

In the example illustrated in FIGS. 10 and 11 (please refer to FIGS. 21 and 22), the shunt valve assembly 10 is in the first mode described above. The first water diversion chamber 1111 is connected to the water inlet 112 and the first water outlet 114 through the water passage 1211 of the first blocking plate 121, and the first water outlet 114 can be connected to the heating device 40. The two second blocking pieces 123 arranged at intervals rotate along with the water diversion valve 12 to respectively open the two second water outlets 115 arranged at intervals. The second water diversion cavity 1112 is simultaneously communicated with the two second water outlets 115 and the water return port 113. The flow of liquid through the diverter valve assembly 10 is illustrated by the dashed arrows in figures 10 and 11.

The third blocking piece 126 is staggered with the water return port 113 along with the rotation of the shunt valve 12, and blocks the second water outlet 115b of the two second water outlets. The two second blocking pieces 123 are staggered with the second water outlet 115a of the two second water outlets. The second water outlet 115a is communicated with the water return port 113, and the second water outlet 115b is blocked from the water return port 113. The second water diversion cavity 1112 is communicated with the second water outlet 115a and the water return port 113.

At this time, after the liquid enters from the water inlet 112, the liquid can flow out from the first water outlet 114 through the first water diversion chamber 1111, and after the liquid is heated by the heating device 40, the liquid can flow back to the second water diversion chamber 1112 through the water return port 113, and can flow out from the second water outlet 115a, and the flow direction of the liquid is shown by an arrow in fig. 3. Thus, the water distribution valve assembly 10 is in a mode of supplying water alone through one second water outlet 115 a. When the water distribution valve assembly 10 is applied to the household appliance 100, the second water outlet 115a may communicate with the third spray arm 33, and the second water outlet 115b may communicate with the first spray arm 31 and the second spray arm 32.

The first water diversion chamber 1111 is connected to the water inlet 112 and the first water outlet 114 through the water passage 1211 of the first blocking plate 121, and the first water outlet 114 can be connected to the heating device 40. The second blocking piece 123a of the two second blocking pieces arranged at intervals rotates along with the shunt valve 12 to open the second water outlet 115a, and the second blocking piece 123b of the two second blocking pieces arranged at intervals rotates along with the shunt valve 12 to close the second water outlet 115 b. The second water outlet 115b is blocked from the water return port 113. The second water diversion cavity 1112 is communicated with the second water outlet 115a and the water return port 113. The flow of liquid through the diverter valve assembly 10 is illustrated by the dashed arrows in fig. 12-13.

In the example shown in FIG. 4, the diverter valve assembly 10 is in the third mode when the diverter valve 12 is rotated to the position shown in FIG. 4. The first blocking piece 121 opens the first water outlet 114 when the shunt valve 12 rotates. The first water dividing chamber 1111 is connected to the water inlet 112 and the first water outlet 114, and the first water outlet 114 is connected to the heating device 40. The third flap 126 rotates to be offset from the return port 113 to open the return port 113. The second blocking piece 123b of the two second blocking pieces blocks the second water outlet 115a of the two second water outlets when the shunt valve 12 rotates. The second water outlet 115a is blocked from the return water inlet 113. The second flap 123a and the second flap 123b are both staggered from the second water outlet 115b to open the second water outlet 115 b. The second water outlet 115b communicates with the return water port 113. The second water diversion cavity 1112 is communicated with the second water outlet 115b and the water return port 113. The water inlet 112 and the first water outlet 114 are located at a side of the first water distribution chamber 1111, and the water return 113 and the two second water outlets are located at a side of the second water distribution chamber 1112.

At this time, after the liquid enters from the water inlet 112, the liquid can flow out from the first water outlet 114 through the first water diversion chamber 1111, and after the liquid is heated by the heating device 40, the liquid can flow back to the second water diversion chamber 1112 through the water return port 113, and can flow out from the second water outlet 115b, and the flow direction of the liquid is shown by an arrow in fig. 4. Thus, the water distribution valve assembly 10 is in a mode of supplying water alone through one second water outlet 115 b.

In the example shown in fig. 14 to 15 (please refer to fig. 21 and 22), the shunt valve assembly 10 is in the third mode, the first shunt chamber 1111 communicates with the water inlet 112 and the first water outlet 114 through the water passage 1211 on the first blocking piece 121, and the first water outlet 114 can communicate with the heating device 40. The second blocking piece 123a of the two second blocking pieces arranged at intervals rotates along with the shunt valve 12 to close the second water outlet 115a, and the second blocking piece 123b of the two second blocking pieces arranged at intervals rotates along with the shunt valve 12 to open the second water outlet 115 b. The second water outlet 115a is isolated from the water return port 113, and the second water outlet 115b is communicated with the water return port 113. The second water diversion cavity 1112 is communicated with the second water outlet 115b and the water return port 113. The flow of liquid through the diverter valve assembly 10 is illustrated by the dashed arrows in figures 14-15.

In the example shown in FIG. 5, the diverter valve assembly 10 is in the fourth mode when the diverter valve 12 is rotated to the position shown in FIG. 5. The diversion valve assembly 10 rotates to make the third blocking piece 126 block the water return port 113, the separating blocking piece 122 blocks the water inlet 112 and the first water outlet 114, the first water outlet 114 and the water return port 113 are both blocked by the separating blocking piece 122 and the water inlet 112, so as to block the flow path between the water inlet 112 and the first water outlet 114, and the heating device 40, and the two second blocking pieces 123 are both staggered with the two second water outlets 115, so that the first diversion cavity 1111 communicates the water inlet 112 and the two second water outlets 115. . The water inlet 112 and the two second water outlets 115 are located at a side of the first water dividing chamber 1111, and the water returning port 113 and the first water outlet 114 are located at a side of the second water dividing chamber 1112.

At this time, after the liquid enters from the water inlet 112, the liquid can directly flow out from the two second water outlets 115 after passing through the first water diversion chamber 1111 without being heated by the heating device 40, and the flowing direction of the liquid is shown by the arrow in fig. 5. The shunt valve assembly 10 can also supply water through the two second water outlets 115 at the same time. When the water distribution valve assembly 10 is applied to the household appliance 100, one second water outlet 115 of the two second water outlets 115 may communicate with the third spray arm 33, and the other second water outlet 115 may communicate with the first spray arm 31 and the second spray arm 32, and the heating device 40 is bypassed, and the water introduced from the water inlet 112 can be directly discharged from the second water outlet 115 without passing through the water return port 113. Thus, when the two second water outlets 115 are opened simultaneously, the three spray arms of the household appliance 100 can spray water which is not heated by the heating device 40, the flow resistance of the dishwasher in a non-heating period can be effectively reduced, and the energy consumption of the dishwasher is further reduced.

In the example illustrated in fig. 16-17 (please refer to fig. 21 and 22), the shunt valve assembly 10 is in the fourth mode described above. The diversion valve 12 rotates to the extent that the water passage 1211 on the first blocking piece 121 is not communicated with the water inlet 112 and the first water outlet 114, the separating blocking piece 122 separates the water inlet 112 and the first water outlet 114, and the first water outlet 114 and the water return port 113 are separated from the water inlet 112 by the separating blocking piece 122. The two second blocking pieces 123 arranged at intervals are staggered with the two second water outlets 115, so that the first water dividing cavity 1111 is communicated with the water inlet 112 and the two second water outlets 115. The first water dividing chamber 1111 is connected to the water inlet 112 and the two second water outlets 115. The flow of liquid through the diverter valve assembly 10 is illustrated by the dashed arrows in fig. 16-17.

When the diverter valve 12 is rotated to the position shown in FIG. 6, the diverter valve assembly 10 is in the fifth mode. When the water diversion valve assembly 10 rotates to the state that the first blocking piece 121 closes the first water outlet 114, the separation blocking piece 122 blocks the water inlet 112 and the first water outlet 114, so that the blocking of the flow path between the water inlet 112 and the first water outlet 114 as well as the heating device 40 is realized. Moreover, the second blocking piece 123b of the two second blocking pieces blocks the second water outlet 115b of the two second water outlets, and the first blocking piece 123a and the second blocking piece 123b are staggered with the second water outlet 115a of the two second water outlets, so that the first water diversion cavity 1111 is communicated with the water inlet 112 and the second water outlet 115 a. The second water outlet 115b is blocked from the water inlet 112 by the second stopper 123 b. Since the separation blade 122 positions the first water outlet 114 and the water return 113 on the low-pressure side of the second water diversion chamber 1112 and positions the water inlet 112 and the two second water outlets on the high-pressure side of the first water diversion chamber 1111, the flow path between the water inlet 112 and the first water outlet 114 and between the water inlet and the heating apparatus 40 can be completely blocked.

At this time, after the liquid enters from the water inlet 112, the liquid can directly flow out from the second water outlet 115b after passing through the first water diversion chamber 1111 without being heated by the heating device 40, and the flow direction of the liquid is shown by the arrow in fig. 6. Thus, the water distribution valve assembly 10 is in a mode of supplying water alone through one second water outlet 115 a. When the water distribution valve assembly 10 is applied to the household appliance 100, the second water outlet 115a may communicate with the third spray arm 33, and the second water outlet 115b may communicate with the first spray arm 31 and the second spray arm 32, and the heating device 40 is bypassed, and the water introduced from the water inlet 112 can be directly discharged from the second water outlet 115a without passing through the return water port 113. By switching the open or close state of the two second water outlets, the first spray arm 31, the second spray arm 32 and the third spray arm 33 of the household appliance 100 can alternately spray water which is not heated by the heating device 40, the flow resistance of the dishwasher in a non-heating period can be effectively reduced, and the energy consumption of the dishwasher can be further reduced. In the example shown in fig. 18 to 19 (please refer to fig. 21 and 22), the shunt valve assembly 10 is in the fifth mode, and the shunt valve 12 is rotated such that the water passage 1211 on the first blocking piece 121 does not communicate with the water inlet 112 and the first water outlet 114, the separating blocking piece 122 separates the water inlet 112 and the first water outlet 114, and the first water outlet 114 and the water return 113 are both separated from the water inlet 112 by the separating blocking piece 122. The second baffle 123b of the two second baffles arranged at intervals closes the second water outlet 115b of the two second water outlets to isolate the second water outlet 115b and the first water dividing cavity 1111, and the second baffle 123a of the two second baffles opens the second water outlet 115a of the two second water outlets to communicate the second water outlet 115a with the first water dividing cavity 1111 and the water inlet 112. The flow of liquid through the diverter valve assembly 10 is illustrated by the dashed arrows in fig. 18-19.

When the shunt valve 12 is rotated to the position shown in fig. 7, the shunt valve assembly 10 is in the sixth mode, and the shunt valve assembly 10 is rotated to enable the first blocking piece 121 to close the first water outlet 114, and the separating blocking piece 122 to block the water inlet 112 and the first water outlet 114, so as to block the flow path between the water inlet 112 and the first water outlet 114, and the heating device 40. Moreover, the second blocking piece 123a of the two second blocking pieces blocks the second water outlet 115a of the two second water outlets, and the first blocking piece 123a and the second blocking piece 123b are staggered with the second water outlet 115b of the two second water outlets, so that the first water diversion cavity 1111 is communicated with the water inlet 112 and the second water outlet 115 b. The second water outlet 115a is blocked from the water inlet 112 by the second stopper 123 a. Since the first blocking piece 121 blocks the first water outlet 114, even if the water return port 113 is located at the high-pressure side of the first water diversion chamber 111, the liquid flowing out of the water inlet 112 does not flow through the heating device 40.

At this time, after the liquid enters from the water inlet 112, the liquid can directly flow out from the second water outlet 115a after passing through the first water diversion chamber 1111 without being heated by the heating device 40, and the flow direction of the liquid is shown by the arrow in fig. 7. Thus, the water distribution valve assembly 10 is in a mode of supplying water alone through one second water outlet 115 a.

It is understood that when the number of the second water outlets is three, and the number of the second blocking pieces is three. When the household appliance 100 needs to be heated by the heating device 40 (i.e., in a heating mode), only one second water outlet of the water diversion valve assembly 10 can be communicated with one spray arm corresponding to the household appliance 100, two second water outlets thereof can also be communicated with two spray arms corresponding to the household appliance 100, and the three second water outlets can also be communicated with three spray arms corresponding to the household appliance 100. That is, in the heating mode, the shunt valve assembly 10 enables switching of the different modes in 7.

When the household appliance 100 does not need to be heated by the heating device 40 (i.e., in a non-heating mode), only one second water outlet of the water diversion valve assembly 10 can be communicated with one spray arm corresponding to the household appliance 100, two second water outlets of the water diversion valve assembly can be communicated with two spray arms corresponding to the household appliance 100, and the three second water outlets can be communicated with three spray arms corresponding to the household appliance 100. That is, in the non-heating mode, the shunt valve assembly 10 is also capable of switching between the different modes in 7. In certain embodiments, the shunt valve 12 includes a fixation portion 124. The second blocking piece 123 is detachably mounted on the fixing portion 124. This facilitates the mounting and dismounting of the second shutter 123. In the present embodiment, the separation blade 122 is fixedly connected to the fixing portion 124. Preferably, the separation blade 122 and the fixing portion 124 are an integral structure. The separating barrier 122 and the second barrier 123 are respectively located at two sides of the fixing portion 124. When the water dividing valve 12 rotates, the partition blade 122 and the fixing portion 124 rotate in the circumferential direction of the water dividing chamber 111, and the first water dividing chamber 1111 and the second water dividing chamber 1112 change with the rotation of the partition blade 122. The second blocking piece 123 rotates along with the fixing portion 124 to open or close the second water outlet 115. In the example shown in fig. 12, the second flap 123 can be pressed to seal the second water outlet 115 under the action of water pressure. Of course, it will be appreciated that in other examples, the second flap can seal the second water outlet under the influence of gravity and can be compressed to effect opening of the second water outlet.

In some embodiments, the housing 11 defines a channel 13 (see fig. 11). The passage 13 communicates with the second water outlet 115. The second flap 123 includes a bottom plate 1231 and first fitting portions 1232 (see fig. 21) extending upward from the bottom plate 1231. The fixing portion 124 is formed with a second fitting portion 1241 fitted with the first fitting portion 1232. The second flap 123 can open or close the inlet 131 of the passage 13 through the bottom plate 1231 to open or close the second water outlet 115 when the shunt valve 12 is rotated.

In the example shown in fig. 20, the first engagement portion 1232 is a tab extending upward from the bottom plate 1231. The second fitting part 1241 is a through-groove formed at a side of the fixing part 124. The tabs can pass through the through slots so that the first engagement portion 1232 can be detachably mounted to the second engagement portion 1241. And the lug can move up and down in the through groove.

In the example shown in fig. 20 and 21, the shunt valve 12 is substantially cylindrical as a whole. The fixing portion 124 has a ring shape. The number of the second stoppers 123 is two. The two second blocking pieces 123 are mounted at intervals on the fixing portion 124 and can move along the circumferential direction of the water diversion cavity 111 along with the fixing portion 124. Also, the bottom plate 1231 has a substantially fan shape. A sealing surface 1233 is formed on the side of the base plate 1231 opposite to the first fitting portion 1232. Under the action of water pressure, the bottom plate 1231 is pressurized to enable sealing of the inlet 131 of the channel 13 by the sealing surface 1233 to seal the second outlet 115.

In certain embodiments, the shunt valve assembly 10 includes a sensor 16. The transmission part 15 includes a transmission member 151, and the sensor 16 detects the position of the transmission member 151. This allows the rotational state of the diverter valve 12 to be determined from the position of the transmission element 151 detected by the sensor 16, which in turn allows rotational control of the diverter valve 12 by means of the transmission element 151, so that switching between different communication states of the diverter valve assembly 10 is achieved precisely by controlling the rotation of the diverter valve 12. The transmission member 151 may be a transmission gear, for example.

In some embodiments, the driving part 141 includes a motor 142. The shunt valve 12 includes an actuation rod 125. An actuator rod 125 extends downwardly from the top of the diverter valve 12. The diverter valve 12 is connected to the drive member 151 via the drive rod 125.
