[0052] The first aspect of this application discloses a water cup assembly for a dishwasher, combined with Figures 1 to 7As shown, in some embodiments, the dishwasher includes a water cup 1000, a drain device 3000, a switch valve 2000, and a blowing device 4000. The water cup 1000 has a water storage chamber 1100, a drain channel 1200, and a water cup outlet 1420. A first overflow port 1410 is provided between the water storage chamber 1100 and the drain channel 1200. The drain channel 1200 and the water cup outlet 1420 are connected. The switch valve 2000 is adapted to open when the dishwasher drains water. The first overflow port 1410, the air blowing device 4000, and the drain channel 1200 are connected to each other to facilitate pumping airflow into the drain channel 1200. The switching valve 2000 is adapted to close the first overflow port 1410 when the air blowing device 4000 pumps airflow into the drain channel 1200, so that the airflow flows sequentially through the drain channel 1200 and the water cup outlet 1420 to blow air into the drain device (3000) to discharge the water in the drain device (3000) using wind pressure.
[0053] By pumping airflow from the air blowing device 4000 to the drain channel 1200, water in the drain device 1200 is discharged using wind pressure. The pumped airflow can simultaneously drive the residual water to flow and / or evaporate, ultimately causing the residual water in the water cup 1000 and the drain device 3000 to be blown to the outside of the dishwasher, thus improving the drying effect of the dishwasher.
[0054] The following is a detailed description of dishwashers. Generally, a dishwasher includes an inner tub (not shown in the figure), a dish rack (not shown in the figure), a water cup 1000, a spray device (not shown in the figure), a washing pump 5000, and a drain device 3000.
[0055] The inner tub has a washing chamber (i.e., the internal space of the inner tub) and an opening that communicates with the washing chamber. The dishwasher door can move between an open position and a closed position. When the door moves to the closed position, it closes the opening; when the door moves to the open position, it opens the opening. Generally, the door is designed to rotate from top to bottom to open the opening and from bottom to top to close the opening.
[0056] The dish rack is installed inside the dishwasher and slides in and out of the washing chamber for easy loading and unloading of dishes. The rack is typically perforated to allow water to flow through and rinse the dishes. Dishware should be understood as any item that can be washed in a dishwasher, including but not limited to bowls, plates, cups, pots, knives, forks, and chopsticks.
[0057] The spray device is used to spray water into the washing chamber, and the water stream is directed at the dishes to rinse and clean them. That is, during the dishwasher's washing cycle, water is sprayed through the spray device to clean the dishes. There are various types of spray devices. The spray device can be movable, moving while spraying water to enhance the rinsing of the dishes. The spray device can also be stationary, spraying water at a fixed angle. Optionally, the spray device includes spray arms that spray water. The number of spray arms can be one, two, three, or more. For example, along a top-to-bottom direction, the spray arms may include an upper spray arm and a lower spray arm, or they may include an upper spray arm, a middle spray arm, and a lower spray arm. The spray arms can rotate synchronously while spraying water. Optionally, the spray device includes fixed nozzles that spray water at a specific angle.
[0058] The spraying of water by the spray device is achieved through the operation of the washing pump 5000. The washing pump 5000 is a key component for realizing the washing cycle. The washing pump 5000 is connected to the water cup 1000, which is located at the bottom of the inner tank for temporary water collection and storage. The washing pump 5000 draws water from the water cup 1000 and delivers it to the spray device. The water flow sprays out from the spray device and rinses the tableware before falling back to the bottom of the inner tank and then flowing back into the water cup 1000, where it is drawn back by the washing pump 5000. This forms a washing cycle to rinse and clean the tableware.
[0059] After the dishwasher finishes its washing cycle, it needs to drain the water. This is achieved by the operation of the drain device 3000. Generally, the drain device 3000 is a drain pump. The drain device 3000 is connected to the water cup 1000 (connected to the water cup outlet 1420). When the drain device 3000 is started, it drains the water in the water cup 1000 and discharges it into the municipal pipeline through the drain pipe 3200.
[0060] After draining, the dishwasher needs to be dried, currently mainly for drying tableware. Water cups 1000 are prone to leaving residual water. In order to avoid the formation of residual water in water cups 1000, this embodiment improves this aspect, reducing or even eliminating residual water to a certain extent, improving the drying effect and preventing the growth of bacteria.
[0061] The water cup 1000 is equipped with a water storage chamber 1100, a drainage channel 1200, and a drainage chamber 1300. A first overflow port 1410 is provided between the water storage chamber 1100 and the drainage channel 1200, and a water cup outlet 1420 is provided between the drainage channel 1200 and the drainage chamber 1300. A switch valve 2000 is used to open or close (i.e., it has both opening and closing functions, the same below) the first overflow port 1410. The water storage chamber 1100 is used to receive washing water from the inner tank. When the drainage device 3000 drains water, the switch valve 2000 opens the first overflow port 1410, connecting the drainage channel 1200 with the water storage chamber 1100. The water flows sequentially through the water storage chamber 1100, the first overflow port 1410, the drainage channel 1200, the water cup outlet 1420, the drainage chamber 1300, and the discharge port 1430, and is discharged through the drain pipe 3200. After the drainage device 3000 finishes draining, water cup 1000 is prone to residual water. This residual water is difficult to drain away by the drainage device 3000. For water cup 1000, since the water flows from the water storage chamber 1100 to the drainage channel 1200 when the drainage device 3000 drains, residual water is more likely to form in the drainage channel 1200 than in the water storage chamber 1100. To remove the residual water, the air blowing device 4000 pumps airflow into the drainage channel 1200. While the air blowing device 4000 is pumping airflow into the drainage channel 1200, the switching valve 2000 closes the first overflow port 1410. The airflow pumped into the drainage channel 1200 cannot enter the water storage chamber 1100 through the first overflow port 1410, but instead exits through the water cup outlet 1420. The airflow carries away the moisture from the drainage channel 1200. The airflow then enters the drainage chamber 1300 through the water cup outlet 1420. Since the drainage device 3000 is installed in the drainage chamber 1300, the airflow... The system can remove moisture from the drain chamber 1300 and drain device 3000. The airflow eventually enters the drain pipe 3200 through the discharge port 1430 and is discharged to the outside of the dishwasher (such as through municipal water pipes) along the drain pipe 3200. As the airflow flows through the drain pipe 3200, it can remove moisture from the drain pipe 3200. This design can reduce the presence of residual water in the water cup 1000, drain device 3000, and / or drain pipe 3200 to a certain extent, or even eliminate the residual water in the water cup 1000, drain device 3000, and / or drain pipe 3200, thereby improving the drying effect of the dishwasher and preventing bacterial growth. Optionally, the air blowing device 4000 includes a fan and an air inlet pipe 4100. One end of the air inlet pipe 4100 is connected to the fan, and the other end blows air towards the drain channel 1200. The fan is an axial flow fan.
[0062] Combination Figure 6 and Figure 7As shown, in some embodiments, the switch valve 2000 is movably disposed in the drain channel 1200. Since the switch valve 2000 can open and close the first flow port 1410, it is configured to be movable to facilitate cooperation with the first flow port 1410 to open or close it. It is understood that the movable nature of the switch valve 2000 can be due to the movement of its internal structure or the overall movement of the switch valve 2000. Therefore, the switch valve 2000 requires a certain amount of space. It can be disposed in the water storage chamber 1100 or in the drain channel 1200. Distributing the switch valve 2000 in the drain channel 1200 is more advantageous for opening or closing the first flow port 1410 during drainage and venting (detailed below).
[0063] In particular, dishwashers generally also include a filter (not shown in the figure), which is connected to the water cup 1000 and installed in the water storage chamber 1100. The filter is used to filter impurities in the water flow, including during the washing cycle and drainage process, to prevent impurities from clogging the washing pump 5000, the spray device and the drainage device 3000. Based on this, the filter already occupies the space of the water storage chamber 1100. By placing the switch valve 2000 in the drainage channel 1200, the components can be arranged more reasonably.
[0064] In some embodiments, the switching valve 2000 is adapted to move away from the first overflow port 1410 to open the first overflow port 1410 under the action of gravity, the water pressure of the water storage chamber 1100 and / or the negative pressure formed by the drainage channel 1200.
[0065] Specifically, let's take the example of the switch valve 2000 moving away from the first overflow port 1410 under the influence of gravity to open the first overflow port 1410. The switch valve 2000 can move away from the first overflow port 1410 from its closed state, thus opening the first overflow port 1410 under the influence of gravity. "Away from" means moving away from; as long as at least a part of the switch valve 2000 moves away from the first overflow port 1410, it can be considered that the switch valve 2000 is moving away from the first overflow port 1410. During the dishwasher's washing cycle, the switch valve 2000 can also switch to the open state of the first overflow port 1410 under the influence of gravity. Thus, when the dishwasher drains water, the drain device 3000 can directly drive the water flow from the water storage chamber 1100 through the first overflow port 1410 and into the drain channel 1200.
[0066] Taking the example of the switch valve 2000 moving away from the first overflow port 1410 under the action of water pressure in the water storage chamber 1100 to open the first overflow port 1410. The switch valve 2000, which can close the first overflow port 1410 by itself, moves away from the first overflow port 1410 under the action of water pressure in the water storage chamber 1100, thereby opening the first overflow port 1410. That is to say, when there is water in the water storage chamber 1100, the water pressure acts on the switch valve 2000, and the direction of the water pressure acting on the switch valve 2000 is away from the first overflow port 1410. Thus, under the action of water pressure, the switch valve 2000 moves away from the first overflow port 1410 to open the first overflow port 1410. In some cases, the switch valve 2000 can open the first overflow port 1410 regardless of whether the dishwasher is in the washing cycle or the draining process.
[0067] Taking the example of the switch valve 2000 moving away from the first overflow port 1410 to open the first overflow port 1410 under the action of negative pressure formed in the drainage channel 1200, when the drainage device 3000 draws and pumps water, it causes negative pressure to be formed in the drainage channel 1200, thus forcing the switch valve 2000 to switch from the state of closing the first overflow port 1410 to the state of opening the first overflow port 1410.
[0068] It is understandable that the switch valve 2000 can open the first overflow port 1410 under any one of the following actions: gravity, water pressure in the water storage chamber 1100, and negative pressure formed in the drainage channel 1200. It can also open the first overflow port 1410 under at least two or all three actions, so there is no need to set up additional control components to control the switch valve 2000 to open the first overflow port 1410.
[0069] In some embodiments, the switching valve 2000 is adapted to move toward the first overflow port 1410 to close the first overflow port 1410 under the action of airflow blowing and / or positive pressure formed by the drain channel 1200.
[0070] Specifically, the switch valve 2000 can move toward the first flow port 1410 from the state of opening the first flow port 1410 under the action of positive pressure formed by the drainage channel 1200, thereby closing the first flow port 1410. "Towards" means "approaching". As long as at least part of the switch valve 2000 approaches the first flow port 1410, it can be regarded as the switch valve 2000 moving toward the first flow port 1410. The movement of the switch valve 2000 can take many forms, including but not limited to rotation, reciprocation or deformation.
[0071] When the air blowing device 4000 pumps airflow, it creates positive pressure in the drainage channel 1200, which is higher than the air pressure in the water storage chamber 1100. This forces the switch valve 2000 to move toward the first flow port 1410 until it comes into contact with the periphery of the first flow port 1410, so that the switch valve 2000 switches from the state of opening the first flow port 1410 to the state of closing the first flow port 1410. There is no need to set up additional control components to control the switch valve 2000 to close the first flow port 1410.
[0072] In some cases, the airflow pumped by the air blowing device 4000 acts on the switching valve 2000 when it enters the drain channel 1200. The airflow blows the switching valve 2000, thereby generating a force on the switching valve 2000, causing the switching valve 2000 to move toward the first flow port 1410 to close the first flow port 1410.
[0073] Combination Figures 6 to 10 As shown, in some embodiments, the switching valve 2000 includes a baffle 2100, which is rotatably disposed in the drain channel 1200. The rotatable arrangement of the baffle 2100 allows it to open or close the first overflow port 1410. For example, the baffle 2100 opens the first overflow port 1410 in its natural state (under the action of gravity) and switches to the closed state (closing the first overflow port 1410) under the action of wind pressure (when the air blowing device 4000 pumps airflow into the drain channel 1200).
[0074] Alternatively, the switching valve 2000 may include a baffle 2100, which is made of a flexible material to accommodate deformation and oscillation. The baffle 2100 is adapted to deform and oscillate to open or close the first flow port 1410. For example, the baffle 2100 may be a rubber sheet or a silicone sheet, with one end fixed and the other end movable, thereby opening or closing the first flow port 1410. For instance, during drainage, the rubber sheet or silicone sheet opens the first flow port 1410 under water pressure, and when the air blowing device 4000 pumps airflow into the drainage channel 1200, the rubber sheet or silicone sheet closes the first flow port 1410 under air pressure.
[0075] Specifically, the baffle 2100 has a first end 2110 and a second end 2120 that are arranged opposite to each other. The first end 2110 is located around the first flow port 1410. Thus, the baffle 2100 is rotatable or swingable through the first end 2110. When the baffle 2100 rotates or swings, the second end 2120 moves away from the first flow port and closer to the first flow port 1410. When the baffle 2100 rotates or swings, causing the second end 2120 to move away from the first flow port 1410, the baffle 2100 opens the first flow port 1410. When the baffle 2100 rotates or swings, causing the second end 2120 to move closer to the first flow port 1410, the baffle 2100 closes the first flow port 1410. The rotatable or swingable arrangement of the baffle 2100 facilitates the opening or closing of the first flow port 1410, which helps to simplify the structure.
[0076] For example, taking the rotatable baffle 2100 as an example, under the action of gravity, the water pressure in the water storage chamber 1100, and / or the negative pressure formed by the drainage channel 1200, the baffle 2100 rotates or swings around the first end 2110, and the second end 2120 moves away from the first overflow port 1410, thus the baffle 2100 opens the first overflow port 1410. Under the action of the positive pressure formed by the drainage channel 1200 and / or the blowing of the airflow, the baffle 2100 rotates in the opposite direction around the first end 2110, and the second end 2120 approaches the first overflow port 1410 until it abuts the periphery of the first overflow port 1410, thus the baffle 2100 closes the first overflow port 1410.
[0077] Optionally, in some embodiments, the baffle 2100 is adapted to rotate upward or swing to close the first flow port 1410, and is adapted to rotate downward or swing to open the first flow port 1410.
[0078] Continuing with the example of a baffle 2100 having a first end 2110 and a second end 2120 that are rotatably positioned opposite each other, when the baffle 2100 opens the first flow port 1410, the baffle 2100 rotates from top to bottom around the first end 2110, causing the second end 2120 to move away from the first flow port 1410 from top to bottom, thereby opening the first flow port 1410. When the baffle 2100 closes the first flow port 1410, the baffle 2100 rotates from bottom to top around the first end 2110, causing the second end 2120 to approach the first flow port 1410 from bottom to top, thereby closing the first flow port 1410. By designing the baffle 2100 to be able to rotate up and down around the first end 2110, the baffle 2100 can open the first overflow port 1410 more smoothly. In some cases, such as when the water storage chamber 1100 is located above the drainage channel 1200, since the drainage channel 1200 forms a certain space in the vertical direction, the up and down rotation of the baffle 2100 can make full use of the space of the drainage channel 1200.
[0079] Combination Figure 6 and Figure 7 As shown, in some embodiments, the water cup 1000 is also provided with an air inlet channel 1450, which is provided with an air outlet 1440 communicating with the drain channel 1200. The airflow pumped by the air blowing device 4000 is suitable to enter the drain channel 1200 through the air inlet channel 1450 and the air outlet 1440. The baffle 2100 has a first end 2110 and a second end 2120 disposed opposite to each other. The baffle 2100 is connected to the periphery of the first overflow port 1410 through the first end 2110 and is rotatable or swingable. The second end 2120 is away from the air outlet 1440 relative to the first end 2110.
[0080] Taking the rotatable baffle 2100 as an example, the baffle 2100 can rotate around the first end 2110, thereby allowing the second end 2120 to move away from or towards the first flow port 1410, thus opening or closing the first flow port 1410. For example, the baffle 2100 can be horizontally positioned when the first flow port 1410 is closed, and tilted when the first flow port 1410 is open. The baffle 2100 can be in either the closed or open state of the first flow port 1410. The air oscillates back and forth, creating a back-and-forth swinging effect. The angle of the back-and-forth swing is generally no more than 90°. Since the second end 2120 is farther away from the air outlet 1440 than the first end 2110, when the airflow enters the drainage channel 1200 from the air outlet 1440, the airflow is more likely to blow the baffle 2100, causing the baffle to rotate from the state of opening the first flow outlet 1410 toward the state of closing the first flow outlet 1410, thereby increasing the speed at which the baffle 2100 closes the first flow outlet 1410.
[0081] Optionally, in some embodiments, the baffle 2100 is adapted to be located in the blowing direction of the air outlet 1440 when the first overflow port 1410 is opened, that is, when the airflow is discharged from the air outlet 1440, it can directly blow onto the baffle 2100, further increasing the speed at which the baffle 2100 closes the first overflow port 1410. It is precisely because the baffle 2100 is located in the blowing direction of the air outlet 1440 when the first overflow port 1410 is opened that, during the drainage process, water flows from the water storage chamber 1100 through the first overflow port 1410 to the drainage channel 1200, and the baffle 2100 can prevent the water flowing towards the drainage channel 1200 from flowing towards the air outlet 1440.
[0082] Combination Figures 3 to 7As shown, in some embodiments, the water storage chamber 1100 is located above the drain channel 1200. The orientation in this document is with reference to the dishwasher in its installed and used state; the side of the dishwasher closest to the ground is the bottom, and the side facing away from the ground is the top. The water storage chamber 1100 is located above the drain channel 1200 and is open upwards, thus communicating with the washing chamber of the inner tub. The water sprayed by the spray device first flows back to the water storage chamber 1100. With this configuration, during drainage, in addition to flowing from the water storage chamber 1100 to the drainage channel 1200 under the action of the drainage device, the water can also flow from the water storage chamber 1100 to the drainage channel 1200 under the action of gravity. In this way, after the drainage device 3000 has finished draining, the presence of residual water in the water storage chamber 1100 is more effectively avoided. Since the residual water in the drainage channel 1200 is generally a small amount (relatively speaking), the drainage channel 1200 is large enough to accommodate the residual water by setting the size of the water storage chamber 1100 and the drainage channel 1200 (generally the water storage chamber 1100 is larger than the drainage channel 1200), and the drainage channel 1200 is then carried away by the airflow, further improving the drying effect of the water cup 1000.
[0083] Optionally, in some embodiments, the bottom of the drain channel 1200 is inclined towards the water outlet 1420 of the cup. This inclined bottom facilitates the flow of water from the drain channel 1200 towards the drain chamber 1300, making it easier for water to leave the drain channel 1200, both during the drainage process and the removal of residual water. Specifically, the lowest point of the drain channel 1200 is not lower than the lowest point of the water outlet 1420 of the cup, further improving the water drainage effect. Furthermore, this arrangement minimizes the amount of residual water in the drain channel 1200 after drainage by the draining device 3000. Optionally, in some embodiments, the lowest point of the drain chamber 1300 is lower than the lowest point of the water outlet 1420 of the cup, making it difficult for water discharged into the drain chamber 1300 to flow back into the drain channel 1200.
[0084] Combination Figures 5 to 9 As shown, in some embodiments, the water cup 1000 includes a detachably configured partition assembly 1500, which is disposed inside the water cup 1000 to separate a water storage chamber 1100 and a drainage channel 1200. The partition assembly 1500 includes a switch valve 2000 and a first overflow port 1410.
[0085] Specifically, the water cup 1000 can be integrally molded, such as by injection molding, forming a large cavity during the integral molding process. By setting a detachable partition component 1500 in this large cavity, the partition component 1500 can divide this large cavity into a water storage cavity 1100 and a drainage channel 1200, which facilitates the formation of a structure in which the water storage cavity 1100 and the drainage channel 1200 are arranged in the vertical direction. Based on this, since the partition component 1500 includes a switch valve 2000 and a first flow port 1410, the switch valve 2000 can be installed after the partition component 1500 is installed in place.
[0086] Combination Figure 2 and Figure 3 As shown, in some embodiments, the discharge port 1430 is provided with a one-way valve 3100. The one-way valve 3100 is unidirectionally open along the discharge direction of the discharge port 1430. When draining, the water flow can open the one-way valve 3100. After the drainage is completed, the one-way valve 3100 closes to prevent the backflow of water in the drain pipe 3200.
[0087] In some embodiments, the air blowing device 4000 is adapted to communicate with the outside environment to draw in outside air. By drawing in outside air, which has a relatively lower temperature and humidity, the air blowing device 4000 is more conducive to drying. In particular, the airflow drawn and pumped by the air blowing device 4000 can be heated to create a hot air drying effect, further enhancing the drying effect.
[0088] In some embodiments, a filter grille is provided on the first outlet to prevent large impurities from entering the drain channel 1200 and clogging the drain channel 1200 during washing and drainage.
[0089] The second aspect of this application discloses a dishwasher, combined with Figures 1 to 12 The dishwasher includes an inner tub and a water cup assembly. The inner tub is provided with a washing chamber, and the water cup 1000 is connected to the washing chamber.
[0090] Optionally, the dishwasher also includes a washing pump 5000 and a diversion valve 6000, which is connected to the air blowing device 4000, the washing pump 5000, the water cup 1000 and the drain device 3000 respectively, and controls the on / off of the air blowing device 4000, the washing pump 5000, the water cup 1000 and the drain device 3000.
[0091] Optionally, the diversion valve 6000 has a first connected state, in which the air blowing device 4000 is connected to the drain device 3000.
[0092] The diversion valve 6000 also has a second connected state, in which the air blowing device 4000 is connected to the drain device 3000 and the water cup 1000.
[0093] The diversion valve 6000 also has a third connection state, in which the air blowing device 4000 is connected to the washing pump 5000.
[0094] The diversion valve 6000 also has a shut-off state, in which the air blowing device 4000 is disconnected from the drain device 3000, the water cup 1000 and the washing pump 5000, while the water cup 1000 and the washing pump 5000 are connected.
[0095] Optionally, the diversion valve 6000 has an air inlet 6400 and a first outlet 6100, a second outlet 6200 and a third outlet 6300. The diversion valve 6000 is located between the water cup 1000 and the washing pump 5000. The first outlet 6100 is connected to the drain device 3000, the second outlet 6200 is connected to the water cup 1000, and the third outlet 6300 is connected to the inlet of the washing pump 5000.
