[0057] The first aspect of the present application discloses a wind distribution device 10, which is combined with Figures 3 to 6 , Figures 13 to 18As shown, in some embodiments, the air distribution device 10 comprises a valve housing 1000 and a valve core 2000, the valve housing 1000 is formed with an air distribution chamber 1130, the valve housing 1000 is provided with an air inlet 1110, a first air outlet 1121 and a second air outlet 1122, the valve core 2000 is rotatably arranged in the air distribution chamber 1130 to open and close (meaning having opening function and closing function, the same below) the air inlet 1110, and open and close the first air outlet 1121 and the second air outlet 1122, the valve core 2000 has a first communication position, a second communication position and a cut-off position; in the first communication position, the valve core 2000 is adapted to open the air inlet 1110 to make the air inlet 1110 and the air distribution chamber 1130 communicate, and at the same time open the first air outlet 1121 and close the second air outlet 1122 to make the first air outlet 1121 and the air distribution chamber 1130 communicate; in the second communication position, the valve core 2000 is adapted to open the air inlet 1110 to make the air inlet 1110 and the air distribution chamber 1130 communicate, and at the same time close the first air outlet 1121 and open the second air outlet 1122 to make the second air outlet 1122 and the air distribution chamber 1130 communicate; in the cut-off position, the valve core 2000 is adapted to close the air inlet 1110 to make the air inlet 1110 and the air distribution chamber 1130 cut off, and at the same time open the first air outlet 1121 and the second air outlet 1122 to make the first air outlet 1121 and the second air outlet 1122 respectively communicate with the air distribution chamber 1130, by such arrangement, the air distribution device 10 has different conduction states, which is suitable for complex fluid conveying requirements.
[0058] Specifically, the air distribution device 10 is applied to the scene where air flow needs to be distributed and flowed, the air inlet 1110 is adapted to communicate with a device providing air flow, for example, the air inlet 1110 communicates with the blowing device 60, the blowing device 60 can pump air flow to the air inlet 1110, generally, the blowing device 60 comprises a fluid machine, the fluid machine provides power required for air flow pumping, the fluid machine includes but is not limited to a fan. When the valve core 2000 opens the air inlet 1110, air flow can enter from the air inlet 1110 and be discharged from the first air outlet 1121 or the second air outlet 1122 to reach a target area. When the valve core 2000 closes the air inlet 1110, air flow cannot enter from the air inlet 1110, or in other words, the blowing device 60 does not need to work at this time, by closing the air inlet 1110, the path to the blowing device 60 is interrupted, and in this state, the first air outlet 1121 and the second air outlet 1122 are opened, the first air outlet 1121 and the second air outlet 1122 communicate to form a path, so as to form part of the path of fluid transmission.
[0059] In this embodiment, the valve core 2000 can switch between the first connected position, the second connected position and the cut-off position in a rotatable manner, thereby opening and closing the air inlet 1110, the first air outlet 1121 and the second air outlet 1122. This helps to reduce the structural complexity of the air distribution device 10, make rational use of space and simplify control.
[0060] In this embodiment, the valve core 2000, in conjunction with the air inlet 1110, the first air outlet 1121, and the second air outlet 1122, can form three conductive states. The first state is that the valve core 2000 is in the first connected position, controlling the air inlet 1110 and the first air outlet 1121 to open while the second air outlet 1122 is closed (the air inlet 1110 and the first air outlet 1121 are connected). The second state is that the valve core 2000 is located in... In the second connected position, valve core 2000 controls the air inlet 1110 and the second air outlet 1122 to open while the first air outlet 1121 is closed (air inlet 1110 and the second air outlet 1122 are connected). In the third state, valve core 3000 is in the cut-off position, and valve core 2000 controls the air inlet 1110 to close while the first air outlet 1121 and the second air outlet 1122 are open (first air outlet 1121 and the second air outlet 1122 are connected).
[0061] More specifically, when the valve core 2000 opens the air inlet 1110, it connects the air inlet 1110 and the air distribution chamber 1130; when the air inlet 1110 is closed, it isolates the air inlet 1110 and the air distribution chamber 1130. That is, when the valve core 2000 opens the air inlet 1110, airflow can enter the air distribution chamber 1130 from the air inlet 1110 and then exit from the first air outlet 1121 or the second air outlet 1122 to reach the target area. When the valve core 2000 closes the air inlet 1110, airflow cannot enter the air distribution chamber 1130 from the air inlet 1110. This design helps to reduce the weight and simplify the structure of the air distribution device 10. It can be understood that airflow entering through the air inlet 1110, as long as it is located in the air distribution chamber 1130, whether directly or indirectly located in the air distribution chamber 1130, can be considered as entering the air distribution chamber 1130.
[0062] When the valve core 2000 opens the first air outlet 1121, it connects the first air outlet 1121 with the air distribution chamber 1130; when it closes the first air outlet 1121, it isolates the first air outlet 1121 from the air distribution chamber 1130. That is, when the valve core 2000 opens the first air outlet 1121, the airflow exits from the air distribution chamber 1130 through the first air outlet 1121 and reaches the target area; when the valve core 2000 closes the first air outlet 1121, the airflow cannot exit from the air distribution chamber 1130 through the first air outlet 1121 and reach the target area.
[0063] When the valve core 2000 opens the second air outlet 1122, it connects the second air outlet 1122 with the air distribution chamber 1130. When the second air outlet 1122 is closed, it isolates the first air outlet 1121 from the air distribution chamber 1130. That is, when the valve core 2000 opens the second air outlet 1122, the airflow exits from the air distribution chamber 1130 through the second air outlet 1122 and reaches the target area. When the valve core 2000 closes the second air outlet 1122, the airflow cannot exit from the air distribution chamber 1130 through the second air outlet 1122 and reach the target area.
[0064] The following explanation will be based on the application of the air distribution device 10 to a dishwasher, or in other words, a dishwasher that includes the air distribution device 10. The dishwasher includes an inner tub (not shown in the figure), a dish rack (not shown in the figure), a water cup 20, a spray device 50, a washing pump 40, a drain pump 30, the air distribution device 10, and a blower device 60.
[0065] 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.
[0066] 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.
[0067] The spray device 50 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 50 to clean the dishes. The spray device 50 can be of various types; it can be movable, moving while spraying water to enhance the rinsing of the dishes. Alternatively, it can be fixed, spraying water at a fixed angle. Optionally, the spray device 50 includes spray arms that spray water. The number of spray arms can be one, two, three, or more. For example, in 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 50 includes fixed nozzles that spray water at a specific angle.
[0068] The spraying device 50 sprays water through the operation of the washing pump 40, which is a key component for realizing the washing cycle. The washing pump 40 is connected to the water cup 20, which is located at the bottom of the inner tank for temporary water collection and storage. The washing pump 40 draws water from the water cup 20 and delivers it to the spraying device 50. The water flows out from the spraying device 50, rinses the tableware, falls back to the bottom of the inner tank, and then flows back into the water cup 20, where it is drawn in by the washing pump 40 again. This forms a washing cycle to rinse and clean the tableware.
[0069] After the dishwasher finishes its washing cycle, it needs to drain the water. This is achieved by the operation of the drain pump 30, which is connected to the water cup 20. When the drain pump 30 starts, it drains the water from the water cup 20 and discharges it into the municipal sewer through the drain pipe.
[0070] After the dishwasher drains, residual water can easily form between the water cup 20 and the washing pump 40. In this embodiment, combined with Figure 1 , Figure 2 , Figures 3 to 6 , Figures 13 to 18 The water cup 20 is connected to the first air outlet 1121, and the washing pump 40 is connected to the second air outlet 1122. When the valve core 2000 opens the air inlet 1110, the corresponding air outlets (first air outlet 1121 and second air outlet 1122) are opened by controlling the air outlets. The airflow pumped by the blower 60 enters from the air inlet 1110 and exits from the first air outlet 1121 to flow to the water cup 20, and exits from the second air outlet 1122 to flow to the washing pump 40. Since the washing pump 40 is connected to the spray device 50, the airflow to the washing pump 40 continues to flow to the spray device 50. In this way, the water in the water cup 20, the washing pump 40 and / or the spray device 50 can be removed, thereby drying the water cup 20, the washing pump 40 and / or the spray device 50 and preventing residual water from breeding bacteria. When valve core 2000 closes air inlet 1110, first air outlet 1121 and second air outlet 1122 open and connect, forming part of the washing cycle path. That is, when valve core 2000 switches to the first state, it can dry water cup 20; when valve core 2000 switches to the second state, it can dry washing pump 40 and spray device 50; when valve core 2000 switches to the third state, it can connect water cup 20 and washing pump 40, forming part of the fluid transmission path in the washing cycle, through which washing pump 40 draws water from water cup 20.
[0071] Combination Figure 6 , Figures 8 to 18As shown, in some embodiments, the valve core 2000 includes a first blocking portion 2310 and a second blocking portion 2320. The first blocking portion 2310 can open and close the air inlet 1110, and the second blocking portion 2320 can open and close the first air outlet 1121 and the second air outlet 1122. The first blocking portion 2310 and the second blocking portion 2320 are adapted to rotate synchronously when the valve core 2000 rotates.
[0072] The opening and closing of the air inlet 1110 is achieved by the first blocking part 2310. The valve core 2000 includes the first blocking part 2310. The valve core 2000 is adapted to open the air inlet 1110 when it is rotated to the point where the first blocking part 2310 is misaligned with the air inlet 1110, and to close the air inlet 1110 when it is rotated to the point where the first blocking part 2310 is opposite to the air inlet 1110. Based on the rotatable setting of the valve core 2000, the opening and closing of the air inlet 1110 can be easily achieved by setting the first blocking part 2310.
[0073] Similarly, the valve core 2000 includes a second blocking portion 2320. The valve core 2000 is adapted to open the first air outlet 1121 when it is rotated to a position where the second blocking portion 2320 and the first air outlet 1121 are misaligned, to open the second air outlet 1122 when it is rotated to a position where the second blocking portion 2320 and the second air outlet 1122 are misaligned, to close the first air outlet 1121 when it is rotated to a position where the second blocking portion 2320 and the first air outlet 1121 are opposite each other, and to close the second air outlet 1122 when it is rotated to a position where the second blocking portion 2320 and the second air outlet 1122 are opposite each other.
[0074] When the valve core 2000 is in the first connected position, the valve core 2000 opens the air inlet 1110 and the first air outlet 1121 and closes the second air outlet 1122. The first shielding part 2310 is offset from the air inlet 1110, the second shielding part 2320 is offset from the first air outlet 1121, and the second shielding part 2320 and the second air outlet 1122 are opposite to each other.
[0075] When the valve core 2000 is in the second connected position, the valve core 2000 opens the air inlet 1110 and the second air outlet 1122 and closes the first air outlet 1121. The first shielding part 2310 is offset from the air inlet 1110, the second shielding part 2320 is opposite to the first air outlet 1121, and the second shielding part 2320 is offset from the second air outlet 1122.
[0076] When the valve core 2000 is in the cut-off position, the valve core 2000 closes the air inlet 1110 and opens the first air outlet 1121 and the second air outlet 1122. The first shielding part 2310 is opposite to the air inlet 1110, the second shielding part 2320 is offset from the first air outlet 1121, and the second shielding part 2320 is offset from the second air outlet 1122.
[0077] Combination Figures 8 to 12 As shown, in some embodiments, the valve core 2000 further includes a first connecting hole 2410, which is coplanar with the first shielding portion 2310. The first connecting hole 2410 is adapted to connect the air distribution chamber 1130 and the air inlet 1110 when the first shielding portion 2310 and the air inlet 1110 are misaligned.
[0078] The first connecting hole 2410 is adapted to connect with the air inlet 1110 to open the air inlet 1110 when the first shielding part 2310 and the air inlet 1110 are misaligned. Optionally, the valve core 2000 also includes a plurality of spaced-apart first connecting holes 2410, where "a plurality of" means two or more. Since the valve core 2000 is rotatably configured, by providing a plurality of spaced-apart first connecting holes 2410, the air inlet 1110 can be opened in different positions by the valve core 2000. Furthermore, since the plurality of first connecting holes 2410 are spaced-apart, this helps to maintain the structural strength of the valve core 2000 (relative to a single large connecting hole).
[0079] Similarly, combining Figures 8 to 12 As shown, in some embodiments, the valve core 2000 further includes a plurality of spaced-apart second connecting holes 2420, which are adapted to communicate with the first air outlet 1121 to open the first air outlet 1121 when the second shielding portion 2320 and the first air outlet 1121 are misaligned, and are also adapted to communicate with the second air outlet 1122 to open the second air outlet 1122 when the second shielding portion 2320 and the second air outlet 1122 are misaligned. In this embodiment, since the second shielding part 2320 needs to cooperate with the first air outlet 1121 and the second air outlet 1122, and the valve core 2000 is rotatably configured, by providing multiple spaced second connecting holes 2420, the valve core 2000 can open the corresponding air outlet (first air outlet 1121, second air outlet 1122) in multiple positions. Since the multiple second connecting holes 2420 are spaced apart, this is beneficial to maintaining the structural strength of the valve core 2000 (relative to a complete large connecting hole).
[0080] It is understandable that, whether for multiple first connecting holes 2410 or multiple second connecting holes 2420, the so-called separation means that there is a separating rib 2500 between two adjacent holes, and the separating rib 2500 makes the two adjacent holes completely or partially separated.
[0081] Combination Figures 3 to 18 As shown, in some embodiments, the air inlet 1110 is provided at one end of the valve housing 1000, the first air outlet 1121 and the second air outlet 1122 are arranged sequentially along the circumferential direction of the valve housing 1000, and the second shielding part 2320 extends along the circumferential direction of the valve core 2000.
[0082] The first blocking part 2310 is located in the axial direction of the valve core 2000, and the second blocking part 2320 is located in the circumferential direction of the valve core 2000. The so-called axial direction is the extension direction of the rotation axis of the valve core 2000, and the circumferential direction is the direction around the rotation axis of the valve core 2000. Since the second shielding part 2320 needs to cooperate with the first air outlet 1121 and the second air outlet 1122, and the first air outlet 1121 and the second air outlet 1122 need to connect to the corresponding target areas, the second shielding part 2320 is set in the circumferential direction. Correspondingly, the first air outlet 1121 and the second air outlet 1122 are located on the peripheral wall of the valve housing 1000. The first shielding part 2310 needs to cooperate with the air inlet 1110. The first shielding part 2310 is set in the axial direction. Correspondingly, the air inlet 1110 is located on the end wall of the valve housing 1000. With this arrangement, it is more conducive to the arrangement of the structure, and the structure of the air distribution device 10 is more compact.
[0083] Optionally, since the valve core 2000 is rotatably mounted and the first shielding part 2310 is located in the axial direction of the valve core 2000, and the first shielding part 2310 is perpendicular to the rotation axis of the valve core 2000, designing the first shielding part 2310 as a planar structure is more conducive to its cooperation with the air inlet 1110. Similarly, since the valve core 2000 is rotatably mounted and the second shielding part 2320 is located in the circumferential direction of the valve core 2000, the trajectory of the second shielding part 2320 is circular or arc-shaped during the rotation of the valve core 2000. Therefore, designing the second shielding part 2320 as an arc-shaped structure is more conducive to its cooperation with the first air outlet 1121 and the second air outlet 1122. Optionally, the first shielding part 2310 and the second shielding part 2320 are arranged vertically. Since the second shielding part 2320 needs to cooperate with the first air outlet 1121 and the second air outlet 1122, and the valve core 2000 is rotatably arranged in the air distribution chamber 1130, the valve housing 1000 also needs to be designed to cooperate with the valve core 2000. By arranging the first shielding part 2310 and the second shielding part 2320 vertically, it is convenient to arrange the first air outlet 1121 and the second air outlet 1122, and to make more reasonable use of space. The first air outlet 1121 and the second air outlet 1122 are arranged sequentially along the circumferential direction of the valve core 2000, which makes it easier for the second shielding part 2320 to cooperate with the corresponding air outlets (first air outlet 1121 and second air outlet 1122), reduces structural complexity, is more conducive to the control of the air distribution device 10, and also has enough space for the first air outlet 1121 and the second air outlet 1122 to be connected to the corresponding target areas through pipelines, making rational use of space.
[0084] Combination Figure 4 , Figure 7 and Figure 11As shown, in some embodiments, along the circumference of the valve core 2000, the arc length of the second blocking portion 2320 is s0, the maximum arc length of the first air outlet 1121 is s1, and the maximum arc length of the second air outlet 1122 is s2, wherein s0 > s1 and s0 > s2. This setting is more conducive to closing the corresponding first air outlet 1121 and second air outlet 1122.
[0085] Combination Figure 4 , Figure 7 and Figure 11 As shown, in some embodiments, on the same plane, the line connecting the center of the first air outlet 1121 and the rotation axis of the valve core 2000 is the first line, and the line connecting the center of the second air outlet 1122 and the rotation axis of the valve core 2000 is the second line; the included angle between the first line and the second line is α1, and the included angle between the two opposite sides of the second shielding part 2320 along the circumferential direction of the valve core 2000 is α2, satisfying α1<α2≤180°.
[0086] The first air outlet 1121 and the second air outlet 1122 are arranged sequentially along the circumferential direction of the valve core 2000, that is, the center of the second air outlet 1122 is offset from the center of the first air outlet 1121 by a certain angle α1 around the rotation center of the valve core 2000. Since the second shielding part 2320 needs to cooperate with the first air outlet 1121 and the second air outlet 1122 to open and close the corresponding air outlets (first air outlet 1121, second air outlet 1122), the included angle between the two opposite sides of the second shielding part 2320 along the circumferential direction of the valve core 2000 is designed to be α2, α1<α2≤180°. In this way, the second shielding part 2320 can correspond only to the first air outlet 1121, or only to the second air outlet 1122, or be staggered from both the first air outlet 1121 and the second air outlet 1122 at the same time. In particular, when this embodiment is applied to a dishwasher, since the space of the dishwasher is limited, this arrangement is more conducive to the connection of the air distribution device 10 with other components through the pipeline, thus optimizing the space arrangement.
[0087] Combination Figures 3 to 12As shown, in some embodiments, the valve core 2000 is composed of separate components connected together. Since the valve core 2000 needs to cooperate with the air inlet 1110 and the first air outlet 1121 and second air outlet 1122, corresponding structures such as the first shielding part 2310 and the second shielding part 2320 are required. To facilitate the implementation of the valve core 2000's structure, designing it as a separate component connection simplifies manufacturing. For example, the valve core 2000 includes a first diverter 2100 and a second diverter 2200 connected together. The first diverter 2100 and the second diverter 2200 are manufactured separately, and then connected and fixed together after manufacturing.
[0088] Optionally, the first diverter 2100 includes a first baffle 2110 extending in the circumferential direction of the valve core 2000, and the second diverter 2200 includes a second baffle 2210 extending in the circumferential direction of the valve core 2000. The first baffle 2110 and the second baffle 2210 are joined together to form a second blocking portion 2320. For example, the first diverter 2100 and the second diverter 2200 are injection molded separately. When the first diverter 2100 and the second diverter 2200 are connected and fixed, the first baffle 2110 and the second baffle 2210 cooperate to form a complete second blocking portion 2320 (the first baffle 2110 and the second baffle 2210 are arc-shaped and joined together).
[0089] Optionally, the first shielding part 2310 is disposed on the end face of the first diverter 2100 near the air inlet 1110, and the first shielding part 2310 is perpendicular to the first baffle 2110, which makes it easier to cooperate with the air inlet 1110 and the structure is more compact.
[0090] Optionally, the second diverter 2200 is further provided with a second connecting hole 2420, which is connected to the air distribution cavity 1130. The second connecting hole 2420 is suitable for connecting the air distribution cavity 1130 and the corresponding first air outlet 1121 and second air outlet 1122 when the first baffle 2110 and the second baffle 2210 are misaligned with the corresponding first air outlet 1121 and second air outlet 1122. This makes it easier to cooperate with the corresponding first air outlet 1121 and second air outlet 1122, and the structure is more compact.
[0091] There are several ways to connect the first diverter 2100 and the second diverter 2200. For example, the first diverter 2100 and the second diverter 2200 can be inserted along the axial direction of the valve core 2000, so that the first diverter 2100 and the second diverter 2200 can mutually constrain each other along the circumferential direction of the valve core 2000. For example, combining... Figure 12As shown, the first diverter 2100 is provided with an insertion hole 2710, and the second diverter 2200 is provided with a pin 2720. The insertion hole 2710 and the pin 2720 are inserted and connected along the axial direction of the valve core 2000. Optionally, the first diverter 2100 and the second diverter 2200 are further fixed by a snap-fit connection to prevent the first diverter 2100 from disengaging from the second diverter 2200.
[0092] Combination Figure 3 and Figure 4 As shown, in some embodiments, the valve housing 1000 includes a housing body 1100 and a sealing cover 1200. One end of the housing body 1100 is open, and the sealing cover 1200 is disposed at one end of the housing body 1100 to enclose the air distribution cavity 1130 with the housing body 1100.
[0093] Specifically, the shell body 1100 has a hollow structure. The peripheral wall of the shell body 1100 is provided with a first air outlet 1121 and a second air outlet 1122. One end of the shell body 1100 is open, and the other end of the shell body 1100 is provided with an air inlet 1110. With this arrangement, the valve core 2000 can be inserted from the open end of the shell body 1100, and then the sealing cover 1200 is covered to enclose the valve core 2000, which facilitates the assembly of the air distribution device 10.
[0094] Combination Figures 8 to 12 As shown, in some embodiments, the housing body 1100 is provided with an air inlet 1110, which is located at the other end of the housing body 1100. The valve core 2000 is adapted to elastically abut against the sealing cover 1200 along the axial direction of the valve core 2000. Optionally, when the air inlet 1110 is located at the other end of the housing body 1100, since the valve core 2000 is installed into the housing body 1100 along the axial direction, and the valve core 2000 needs to open and close the air inlet 1110, the elastic abutment between the sealing cover 1200 and the valve core 2000 allows the valve core 200 to be pressed against the other end of the housing body 1100, making the closure of the air inlet 1110 more reliable.
[0095] Combination Figures 8 to 12 As shown, in some embodiments, the valve core 2000 includes an elastic arm 2600 adapted to abut against and elastically deform with the sealing cap 1200. The elastic arm 2600 is integrally formed with the second diverter 2200. When the sealing cap 1200 is connected to the housing body 1100, the sealing cap 1200 abuts against the elastic arm 2600, and the elastic arm 2600 elastically deforms, forcing the valve core 2000 to press against the other end of the housing body 1100.
[0096] Combination Figure 3 and Figure 4As shown, in some embodiments, the air distribution device 10 further includes a motor and a drive shaft 3000. The drive shaft 3000 passes through the sealing cover 1200 to connect to the valve core 2000. The motor is adapted to drive the valve core 2000 to rotate via the drive shaft 3000. Optionally, the second air distribution member 2200 has a rotating shaft 2220 on the side away from the air inlet 1110. The rotating shaft 2220 is used to connect to the drive shaft 3000 of the motor to drive the valve core 2000 to rotate.
[0097] The second aspect of this application discloses a drying system for a dishwasher, combined with Figures 1 to 18 As shown, the dishwasher includes the aforementioned air distribution device 10. The air distribution device 10 includes a valve housing 1000 and a valve core 2000. An air distribution chamber 1130 is formed within the valve housing 1000. The valve housing 1000 has an air inlet 1110, a first air outlet 1121, and a second air outlet 1122. The valve core 2000 is rotatably disposed within the air distribution chamber 1130 to open and close the air inlet 1110, and to open and close the first air outlet 1121 and the second air outlet 1122. The valve core 2000 has a first connecting position, a second connecting position, and a closed position. In the first connecting position, the valve core 2000 is adapted to open the air inlet 1110 to connect the air inlet 1110 and the air distribution chamber 1130, and simultaneously open the first air outlet 1121 and close the second air outlet 1122. In the first air outlet 1121 and the air distribution chamber 1130 are connected; in the second connected position, the valve core 2000 is adapted to open the air inlet 1110 to connect the air inlet 1110 and the air distribution chamber 1130, and simultaneously close the first air outlet 1121 and open the second air outlet 1122 to connect the second air outlet 1122 and the air distribution chamber 1130; in the closed position, the valve core 2000 is adapted to close the air inlet 1110 to isolate the air inlet 1110 and the air distribution chamber 1130, and simultaneously open the first air outlet 1121 and the second air outlet 1122 to connect the first air outlet 1121 and the second air outlet 1122 to the air distribution chamber 1130 respectively. Through this arrangement, the air distribution device 10 has different conduction states, suitable for complex fluid transport requirements. It is understood that the air distribution device 10 of the dishwasher in this embodiment adopts the technical solution of the above embodiment, and therefore has at least the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.
[0098] Combination Figures 1 to 18As shown, in some embodiments, the dishwasher further includes a water cup 20, a washing pump 40, and a blower 60. A first air outlet 1121 is adapted to communicate with the water outlet of the water cup 20, a second air outlet 1122 is adapted to communicate with the inlet of the washing pump 40, and the blower 60 is adapted to communicate with the air inlet 1110. In the first communication position, the blower 60 is adapted to pump airflow toward the water cup 20; in the second communication position, the blower 60 is adapted to pump airflow toward the washing pump 40. Optionally, the blower includes a fan and an air inlet pipe 61, one end of the air inlet pipe is connected to the fan, and the other end is connected to the air inlet 1110. The fan is an axial flow fan.
[0099] Furthermore, at the cut-off position, the washing pump 40 is adapted to draw water from the water cup 20 through the air distribution device 10, and the water flow is adapted to flow sequentially through the first air outlet 1121 and the second air outlet 1122 to enter the washing pump 40.
[0100] Specifically, when the valve core 2000 opens the air inlet 1110 and the first air outlet 1121 and closes the second air outlet 1122, the airflow pumped by the blower 60 can enter from the air inlet 1110 and exit from the first air outlet 1121 to the drain pump 30, carrying away the moisture in the drain pump 30, reducing or even eliminating the presence of residual water in the drain pump 30, and improving the drying effect.
[0101] When the valve core 2000 opens the air inlet 1110 and the second air outlet 1122 and closes the first air outlet 1121, the airflow pumped by the blower 60 can enter through the air inlet 1110 and exit through the second air outlet 1122 to the washing pump 40, carrying away moisture from the washing pump 40 and the spray device 50, reducing or even eliminating the presence of residual water in the washing pump 40 and the spray device 50, and improving the drying effect. Since the spray device 50 is connected to the inner tank, the airflow sprayed from the spray device 50 can also dry the inner tank (tableware).
[0102] When the valve core 2000 closes the air inlet 1110 and opens the first air outlet 1121 and the second air outlet 1122, the washing pump 40 draws water from the water cup 20 through the air distribution device 10. The water flow is suitable for flowing from the water cup 20 through the first air outlet 1121 and the second air outlet 1122 to enter the washing pump 40. The washing pump 40 pumps water towards the spray device 50. After the water is sprayed out by the spray device 50, it falls back into the water cup 20 and continues to be drawn by the washing pump 40.
[0103] A third aspect of this application discloses a dishwasher that includes the drying system of the dishwasher described above.
[0104] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application.
