Description

Technical Field

[0001] The invention relates to the technical field of household appliances, and in particular to a water diversion valve component and a household appliance. Background Art

[0002] Usually, in order to improve the washing effect of tableware, a dishwasher is usually equipped with a heating device. By heating the washing water, the high-temperature washing water can wash away the contaminants on the tableware and bring heat to the tableware, so that the dishwasher system can achieve a higher cleaning rate and drying rate in a shorter washing time. However, due to the limitations of the system structure, when the washing water passes through the heating device, the flow resistance of the water side channel is relatively large, which will cause problems such as a decrease in the spray pressure of the dishwasher spray arm or an increase in the power consumption of the washing pump. The heating process only occupies a part of the total washing time of the dishwasher. If the heating system is directly connected to the washing water circulation flow path, during the non-heating period, the resistance loss caused by the water flowing through the heating device will cause the spray arm water flow pressure to decrease and the washing water flow rate to decrease, resulting in a poor dishwashing effect.

[0054] Please combine Figure 1 and Figure 8 and 9 The water diversion valve assembly 10 of the embodiment of the present invention can be applied to the household appliance 100 of the embodiment of the present invention. In one example, the household appliance 100 can be a dishwasher or other household cleaning equipment that requires the use of liquid (such as water).

[0055] The household appliance 100 includes a water diversion valve assembly 10, a cavity 20, a spray arm 30, and a heating device 40. A cavity 21 is formed in the cavity 20. The spray arm 30 is at least partially disposed in the cavity 21. The spray arm 30 is provided with a plurality of spray holes (not shown). The detergent can be sprayed into the cavity 21 through the plurality of spray holes to clean the items (such as tableware) in the cavity 21. Figure 1 In the example shown, the spray arm 30 includes a first spray arm 31, a second spray arm 32, and a third spray arm 33 that are spaced apart. 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, respectively. 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 in the chamber 21, respectively. The heating device 40 is used to heat the washing water, and the heated washing water may be sprayed out through the spray holes of the spray arm 30.

[0056] The water diversion valve assembly 10 includes a housing 11 and a water diversion valve 12. A water diversion 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 connected to the water return port 113 through an external pipeline of the housing 11. The water diversion valve 12 is disposed in the water diversion chamber 111 and can divide the water diversion chamber 111 into a first water diversion chamber 1111 and a second water diversion chamber 1112 separated from each other. The first water diversion chamber 1111 is connected to the water inlet 112. The water diversion valve 12 can rotate in the water diversion chamber 111 to connect the first water diversion chamber 1111 to the water inlet 112 and the first water outlet 114 and to connect the second water diversion chamber 1112 to the second water outlet 115 and the return water port 113, and to isolate the water inlet 112 and the first water outlet 114 and to connect the first water diversion chamber 1111 to the water inlet 112 and the second water outlet 115.

[0057] It should be noted that when the water diverter valve 12 rotates in the water diverter chamber 111, the water diverter valve assembly 10 can realize the first state and the second state described below. The first state and the second state are different states. Specifically, when the water diverter valve 12 rotates to make the first water diverter chamber 1111 connect to the water inlet 112 and the first water outlet 114, the second water diverter chamber 1112 can connect to the second water outlet 115 and the return water port 113, that is, the first state of the water diverter valve assembly 10 is realized, and at this time, the water through the water inlet 112 can flow out from the first water outlet 114 through the first water diverter chamber 1111, and the water flowing out of the first water outlet 114 can flow into the second water diverter chamber 1112 through the return water port 113, and flow out from the second water outlet 115 through the second water diverter chamber 1112. When the household appliance 100 needs to be heated by the heating device 40, the water diverter valve assembly 10 can be placed in the first state described above, and at this time, the household appliance 100 can be considered to be in the heating mode. When the water diverter valve 12 rotates to isolate the water inlet 112 and the first water outlet 114, the first water diverter chamber 1111 is connected to the water inlet 112 and the second water outlet 115, that is, the second state of the water diverter valve assembly 10 is achieved, and the water passing through the water inlet 112 can flow directly out of the second water outlet 115 through the first water diverter chamber 1111. When the household appliance 100 does not need to be heated by the heating device 40, the water diverter valve assembly 10 can be in the above-mentioned second state, and the household appliance 100 can be considered to be in a non-heating mode.

[0058] In this embodiment, the household appliance 100 further includes a sump 50 and a washing pump 60. The washing liquid sprayed onto the washing items can be collected in the sump 50 at the bottom of the chamber 21. A washing outlet 201 is provided at the bottom of the sump 50. The washing liquid flows out from the washing outlet 201. The inlet of the washing pump 60 is connected to the washing outlet 201, and the outlet of the washing pump 60 is connected to the water inlet 112, so that the washing liquid is powered by the washing pump 60. The heating device 40 is connected to the first water outlet 114 and the water return port 113 through a pipeline.

[0059] In this way, when the water diversion 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. In this way, when it is necessary to heat the water, the water diversion valve 12 can be rotated to connect the first water diversion chamber 1111 to the water inlet 112 and the first water outlet 114. At this time, the water entering through the water inlet 112 can flow out from the first water outlet 114 through the first water diversion chamber 1111 and be heated by the heating device 40, and the water heated by the heating device 40 can flow into the second water diversion chamber 1112 through the return port 113 and can be discharged from the second water outlet 114. 115 flows to the spray arm 30 for spraying. When there is no need to heat the water, the water diverter valve 12 can be rotated to separate the water inlet 112 and the first water outlet 114. At this time, the water entering through the water inlet 112 can flow directly from the second water outlet 115 to the spray arm 30 for spraying via the first water diverter chamber 1111. In this way, the water does not need to flow through the heating device 40, which can reduce the resistance in the water flow system during the non-heating period, reduce the problems of increased power consumption of the washing pump 60 and long washing time, and thus improve the system washing performance of the household appliance 100.

[0060] Of course, it is understood that the external pipeline connecting the first water outlet 114 and the water return port 113 may also be provided with other equipment (such as multiple heating devices), which may be provided according to specific circumstances. Figure 1 In the example shown, the heating device 40 adopts a heat pump system, which includes a compressor 41, a condenser 42, a throttling device 43 and an evaporator 44. Furthermore, the compressor 41, the condenser 42, the throttling device 43, and the evaporator 44 are connected in sequence through pipelines to form a closed circulation system, and the refrigerant circulates in the closed circulation system.

[0061] It is understandable that when the water diverter valve 12 blocks the water inlet 112 and the first water outlet 114 , the water diverter valve 12 may also close the water return port 113 to block the second water outlet 115 from the water return port 113 .

[0062] It should be noted that when the water diverter valve 12 rotates in the water diverter chamber 111, the spaces corresponding to the first water diverter chamber 1111 and the second water diverter chamber 1112 are changed. The pressure of the liquid entering the first water diverter chamber 1111 from the water inlet 112 is greater than the pressure of the liquid entering the second water diverter chamber 1112 from the water return port 113 (due to the pressure drop loss of the liquid flow). Therefore, the first water diverter chamber 1111 can be regarded as a high-pressure chamber, and the second water diverter chamber 1112 can be regarded as a low-pressure chamber.

[0063] Please combine Figure 2 and Figure 7 In some embodiments, the water diverter valve 12 has a first baffle 121. The first baffle 121 can open or close the first water outlet 114 when the water diverter valve 12 rotates. Figure 2In the example shown, the first baffle 121 rotates with the water diversion valve 12 and is staggered from the first water outlet 114 to connect the water inlet 112 and the first water outlet 114. Figure 7 In the example shown, the first baffle 121 closes the first water outlet 114 to prevent liquid from entering the heating device 40 through the first water outlet 114. It can be understood that the shape of the first baffle 121 can be set according to specific circumstances, such as a circular or elliptical shape.

[0064] Please combine Figures 10 to 21 In some embodiments, the first baffle 121 is provided with a water hole 1211. When the water diverter valve 12 rotates, the first baffle 121 can connect the first water outlet 114 and the first water diverter chamber 1111 through the water hole 1211. In this way, when the water hole 1211 is not connected to the first water outlet 114, the first baffle 121 separates the first water outlet 114 and the first water diverter chamber 1111. It can be understood that the way the water hole 1211 is opened can be set according to specific circumstances. The number of water holes 1211 can be multiple. For example, in Fig.18 In the example shown, the water through hole 1211 of the first baffle 121 is not connected to the first water outlet 114 to close the first water outlet 114 .

[0065] In some embodiments, the water diverter valve 12 has a partitioning baffle 122. The partitioning baffle 122 divides the water diverter chamber 111 into a first water diverter chamber 1111 and a second water diverter chamber 1112. The partitioning baffle 122 can rotate in the water diverter chamber 111 to connect the water inlet 112 and the first water outlet 114 or to block the water inlet 112 and the first water outlet 114.

[0066] Specifically, when the partition baffle 122 rotates in the water diversion chamber 111 to connect the water inlet 112 and the first water outlet 114, the water diversion valve assembly 10 is in the above-mentioned first state. When the partition baffle 122 rotates in the water diversion chamber 111 to block the water inlet 112 and the first water outlet 114, the water diversion valve assembly 10 is in the above-mentioned second state.

[0067] It can be understood that the shape of the partition baffle 122 can be set according to specific circumstances.

[0068] In some embodiments, the partition baffle 122 includes a baffle body 1221 and two baffle connecting pieces 1222 connected to both sides of the baffle body 1221 (see Fig.14 and Fig.15 The two baffle connecting pieces 1222 are respectively attached to the inner wall 1110 of the water diversion chamber 111. The baffle connecting piece 1222 is attached to the inner wall 1110 of the water diversion chamber 111 to seal the gap between the baffle connecting piece 1222 and the inner wall 1110 of the water diversion chamber 111 to ensure the water diversion effect of the water diversion valve assembly 10.

[0069] It can be understood that the baffle body 1221 and the two baffle connecting pieces 1222 can adopt an integral structure or a split structure.

[0070] In some embodiments, the baffle connecting piece 1222 is connected to the inner wall 1110 of the water diversion chamber 111 in an arc shape. This provides a better sealing effect. Specifically, the first arc surface formed by the baffle connecting piece 1222 is attached to the second arc surface formed by the inner wall 1110 of the water diversion chamber 111.

[0071] In some embodiments, the water diverter valve 12 has a second baffle 123. The second baffle 123 can open or close the second water outlet 115 when the water diverter valve 12 rotates. In this way, the second water outlet 115 is opened or closed by the position change of the second baffle 123 as the water diverter valve 12 rotates.

[0072] Specifically, when the water diversion valve 12 rotates to open the second water outlet 115, the liquid in the water diversion chamber 111 can flow out from the second water outlet 115. When the water diversion valve 12 rotates to close the second water outlet 115, the liquid in the water diversion chamber 111 will not flow out from the second water outlet 115.

[0073] In some embodiments, there are multiple second water outlets 115, multiple second baffles 123, and the number of second baffles 123 is the same as the number of second water outlets 115. In this way, the positions of multiple second baffles 123 can be rotated to open or close different second water outlets 115.

[0074] In some examples (please combine Figure 2 , Figures 4 to 7 and Figures 9 to 18 ), the number of the second water outlets 115 is two. The number of the second baffles 123 is two. The two second water outlets 115 are arranged at intervals. The two second baffles 123 are arranged at intervals.

[0075] In some examples, the number of the second water outlets is three. The number of the second baffles is three. The three second water outlets are spaced apart. The three second baffles are spaced apart. At this time, the number of the second water outlets of the water diversion valve assembly 10 is consistent with the spray arm 30 of the household appliance 100. The three second water outlets can be respectively connected to the first spray arm 31, the second spray arm 32 and the third spray arm 33 to achieve different application modes.

[0076] Of course, it is understandable that the number of the second water outlets may be 4 or 5, etc., and the number of the second baffles may be 4 or 5, etc., which is not limited here.

[0077] Please combine Figures 2 to 7In some embodiments, the water diverter valve 12 has a third baffle 126. The third baffle 126 can open or close the water return port 113 when the water diverter valve 12 rotates.

[0078] For example, in Figure 2 In the example shown, the third baffle 126 opens the water return port 113 to connect the water return port 113 with the two second water outlets 115. Figure 5 In the example shown, the third baffle 126 closes the water return port 113 to achieve a better sealing effect on the water return port 113 .

[0079] Please combine Figures 2 to 7 The water diverter valve 12 has a first baffle 121, two second baffles 123 and a third baffle 126.

After being heated by the heating device 40, it flows back to the second water diversion chamber 1112 through the water return port 113, and can flow out from the second water outlet 115b. The flow direction of the liquid is as follows: Figure 4 As shown by the arrow. In this way, the water diversion valve assembly 10 is in a mode of supplying water separately through a second water outlet 115b.

The flow of liquid in the water diverter valve assembly 10 is as follows: Figure 14 to Figure 15 As shown by the dotted arrow.

[0090] exist Figure 5 In the example shown, when the water diverter valve 12 is rotated to Figure 5When the water diversion valve assembly 10 is in the fourth mode, the water diversion valve assembly 10 is rotated so that the third baffle 126 blocks the return water port 113, the partition baffle 122 blocks the water inlet 112 and the first water outlet 114, and the first water outlet 114 and the return water port 113 are both separated from the water inlet 112 by the partition baffle 122, thereby blocking the flow path between the water inlet 112 and the first water outlet 114 and the heating device 40, and the two second baffles 123 are staggered with the two second water outlets 115, so that the first water diversion chamber 1111 is connected to the water inlet 112 and the two second water outlets 115. The water inlet 112 and the two second water outlets 115 are located on the side where the first water diversion chamber 1111 is located, and the return water port 113 and the first water outlet 114 are located on the side where the second water diversion chamber 1112 is located.

[0091] At this time, after the liquid enters from the water inlet 112, it 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. The flow direction of the liquid is as follows: Figure 5 As shown by the arrow. At this time, the water diverter valve assembly 10 can also supply water through the two second water outlets 115 at the same time.

[0092] exist Figure 16 to Figure 17 In the example shown (please combine Fig.21 and Fig. 22 ), the water diverter valve assembly 10 is in the fourth mode mentioned above. The water diverter valve 12 is rotated so that the water hole 1211 on the first baffle 121 is not connected to the water inlet 112 and the first water outlet 114, the partition baffle 122 separates the water inlet 112 and the first water outlet 114, and the first water outlet 114 and the return water port 113 are both separated from the water inlet 112 by the partition baffle 122. The two second baffles 123 arranged at intervals are staggered from the two second water outlets 115, so that the first water diverter chamber 1111 is connected to the water inlet 112 and the two second water outlets 115. The first water diverter chamber 1111 is connected to the water inlet 112 and the two second water outlets 115. The flow of liquid in the water diverter valve assembly 10 is as follows: Figure 16 to Figure 17 As shown by the dotted arrow.

[0093] When the water diverter valve 12 is turned to Figure 6When the water diversion valve assembly 10 is in the fifth mode, the water diversion valve assembly 10 is rotated so that the first baffle 121 closes the first water outlet 114, and the partition baffle 122 separates the water inlet 112 and the first water outlet 114, thereby blocking the flow path between the water inlet 112 and the first water outlet 114 and the heating device 40. In addition, the second baffle 123b of the two second baffles blocks the second water outlet 115b of the two second water outlets, and the first baffle 123a and the second baffle 123b are staggered with the second water outlet 115a of the two second water outlets, so that the first water diversion chamber 1111 is connected to the water inlet 112 and the second water outlet 115a. The second water outlet 115b is blocked by the second baffle 123b and separated from the water inlet 112. Due to the partition baffle 122, the first water outlet 114 and the return water port 113 are located on the low-pressure side of the second water diversion chamber 1112, and the water inlet 112 and the two second water outlets are located on the high-pressure side of the first water diversion chamber 1111, so that the flow path between the water inlet 112 and the first water outlet 114 and the heating device 40 can be completely blocked.

[0094] At this time, after the liquid enters from the water inlet 112, it 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. The flow direction of the liquid is as follows: Figure 6 As shown by the arrow. In this way, the water diversion valve assembly 10 is in a mode of supplying water separately through a second water outlet 115a. When the water diversion valve assembly 10 is applied to the household appliance 100, the second water outlet 115a can be connected to the third spray arm 33, and the second water outlet 115b can be connected to the first spray arm 31 and the second spray arm 32, and the heating device 40 is bypassed, and the water entering from the water inlet 112 can be discharged directly from the second water outlet 115a without passing through the return port 113. By switching the open or closed state of the two second water outlets in this way, the first spray arm 31 and the second spray arm 32 and the third spray arm 33 of the household appliance 100 can alternately spray water that is not heated by the heating device 40, which can effectively reduce the flow resistance of the dishwasher during the non-heating period and further reduce the energy consumption of the dishwasher. Figure 18 to Figure 19 In the example shown (please combine Fig.21 and Fig. 22), the water diverter valve assembly 10 is in the fifth mode mentioned above, and the water diverter valve 12 is rotated so that the water hole 1211 on the first baffle 121 is not connected to the water inlet 112 and the first water outlet 114, and the partition baffle 122 separates the water inlet 112 and the first water outlet 114, and the first water outlet 114 and the return water port 113 are both separated from the water inlet 112 by the partition baffle 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 separate the second water outlet 115b from the first water diverter chamber 1111, and the second baffle 123a of the two second baffles opens the second water outlet 115a of the two second water outlets to connect the second water outlet 115a with the first water diverter chamber 1111 and the water inlet 112. The flow of liquid in the water diverter valve assembly 10 is as follows: Figure 18 to Figure 19 As shown by the dotted arrow.

[0095] When the water diverter valve 12 is turned to Figure 7 When the water diverter valve assembly 10 is in the sixth mode, the water diverter valve assembly 10 rotates so that the first baffle 121 closes the first water outlet 114, and the partition baffle 122 separates the water inlet 112 and the first water outlet 114, thereby blocking the flow path between the water inlet 112 and the first water outlet 114 and the heating device 40. In addition, the second baffle 123a of the two second baffles blocks the second water outlet 115a of the two second water outlets, and the first baffle 123a and the second baffle 123b are staggered with the second water outlet 115b of the two second water outlets, so that the first water diverter chamber 1111 communicates with the water inlet 112 and the second water outlet 115b. The second water outlet 115a is blocked by the second baffle 123a and separated from the water inlet 112. Since the first baffle 121 blocks the first water outlet 114 , even if the water return port 113 is located at the side of the high-pressure first water diversion chamber 111 , the liquid flowing out of the water inlet 112 will not flow through the heating device 40 .

[0096] At this time, after the liquid enters from the water inlet 112, it can directly flow out from the second water outlet 115a after passing through the first water diversion cavity 1111 without being heated by the heating device 40. The flow direction of the liquid is as follows: Figure 7 As shown by the arrow. In this way, the water diversion valve assembly 10 is in a mode of supplying water separately through a second water outlet 115a.

[0097] It can be understood that when the number of the second water outlets is three and the number of the second baffles is three. When the household appliance 100 needs to be heated by the heating device 40 (i.e., heating mode), the three second water outlets of the water diverter valve assembly 10 can be only one second water outlet connected to a spray arm corresponding to the household appliance 100, or two of the second water outlets can be connected to two spray arms corresponding to the household appliance 100, or all three second water outlets can be connected to three spray arms corresponding to the household appliance 100. That is, in the heating mode, the water diverter valve assembly 10 can switch between 7 different modes.

[0098] When the household appliance 100 does not need to be heated by the heating device 40 (i.e., non-heating mode), the three second water outlets of the water diverter valve assembly 10 can also be that only one of the second water outlets is connected to a spray arm corresponding to the household appliance 100, or two of the second water outlets are connected to two spray arms corresponding to the household appliance 100, or all three second water outlets are connected to three spray arms corresponding to the household appliance 100. That is, in the non-heating mode, the water diverter valve assembly 10 can also switch between 7 different modes. In some embodiments, the water diverter valve 12 includes a fixing portion 124.

The partition baffle 122 and the second baffle 123 are respectively located on both sides of the fixing portion 124. When the water diverter valve 12 rotates, the partitioning baffle 122 and the fixing portion 124 rotate along the circumference of the water diverter chamber 111, and the first water diverter chamber 1111 and the second water diverter chamber 1112 change with the rotation of the partitioning baffle 122. The second baffle 123 rotates with the fixing portion 124 to open or close the second water outlet 115. Fig.12 In the example shown, under the action of water pressure, the second baffle 123 can be compressed to seal the second water outlet 115. Of course, it can be understood that in other examples, the second baffle can seal the second water outlet under the action of gravity and can be compressed to open the second water outlet.

[0099] In some embodiments, the housing 11 is provided with a channel 13 (see Fig.11 The channel 13 is connected to the second water outlet 115. The second baffle 123 includes a bottom plate 1231 and a first matching portion 1232 extending upward from the bottom plate 1231 (see Fig.21 The fixing portion 124 is formed with a second matching portion 1241 that matches with the first matching portion 1232. The second baffle 123 can open or close the inlet 131 of the channel 13 through the bottom plate 1231 to open or close the second water outlet 115 when the water diversion valve 12 rotates.

[0100] exist Fig. 20 In the example shown, the first matching portion 1232 is a convex piece extending upward from the bottom plate 1231. The second matching portion 1241 is a through slot formed on the side of the fixing portion 124. The convex piece can penetrate the through slot so that the first matching portion 1232 can be detachably mounted on the second matching portion 1241. In addition, the convex piece can move up and down in the through slot.

The two second baffles 123 are installed at intervals on the fixing portion 124 and can move along the circumferential direction of the water diverter chamber 111 with the fixing portion 124. In addition, the bottom plate 1231 is generally fan-shaped. A sealing surface 1233 is formed on one side of the bottom plate 1231 opposite to the first matching portion 1232. Under the action of water pressure, the bottom plate 1231 is compressed and can seal the inlet 131 of the channel 13 through the sealing surface 1233 to seal the second water outlet 115.

The transmission part 15 includes a transmission member 151, and the sensor 16 is used to detect the position of the transmission member 151. In this way, the rotation state of the water diverter valve 12 can be determined according to the position of the transmission member 151 detected by the sensor 16, and then the rotation of the water diverter valve 12 can be controlled by the transmission member 151, so as to accurately switch the different connection states of the water diverter valve assembly 10 by controlling the rotation of the water diverter valve 12. Among them, the transmission member 151 can be, for example, a transmission gear.

[0105] In some embodiments, the driving part 141 includes a motor 142. The water diverter valve 12 includes a driving rod 125.

[0106] In this embodiment, the driving rod 125 extends downward from the partition baffle 122. The fixing portion 124 surrounds the driving rod 125. The water diversion valve 12 is connected to the transmission member 151 through the driving rod 125. The driving rod 125 can be connected to the transmission member 151 by a snap-on method. The motor 142 is used to drive the transmission member 151 to rotate so as to drive the driving rod 125 to rotate.

[0107] In this embodiment, the first baffle 121, the driving rod 125, the partition baffle 122 and the fixing portion 124 are an integrated structure, which is easy to process and has better overall stability of the water diversion valve 12.

[0108] It can be understood that in order to ensure the stability of the operation of the driving part 141 and the transmission part 15, a fixed cover plate 19 can be set, and the motor 142 and the transmission member 151 are respectively arranged on opposite sides of the fixed cover plate 19, and the rotating shaft of the motor 142 passes through the fixed cover plate 19 and is connected to the transmission member 151.

[0109] In some embodiments, the housing 11 includes a lower housing 17 and an upper housing 18. The lower housing 17 is connected to the upper housing 18. The connection method between the lower housing 17 and the upper housing 18 can be set according to specific circumstances.
