[0046] The first aspect of the present application discloses a blowing assembly 1000, which is combined with Figures 5 to 8 As shown, in some embodiments, the blowing assembly 1000 comprises an air duct 1100, an air wheel 1200 and a motor 1300, the air duct 1100 is provided with an air inlet 1110 and an air outlet 1120, the air wheel 1200 is arranged inside the air duct 1100, the air wheel 1200 is used to drive the airflow to flow into the air inlet 1110 and flow out of the air outlet 1120 when rotating, the motor 1300 is arranged outside the air duct 1100, and the motor 1300 is connected with the air wheel 1200 to drive the air wheel 1200 to rotate. By arranging the motor 1300 outside the air duct 1100, when the airflow flows along the air duct 1100, the moisture or other impurities in the airflow will not contact the motor 1300, avoiding damage to the motor 1300 and ensuring the normal operation of the blowing assembly 1000.

[0047] The following will be described in detail in combination with a dishwasher. The dishwasher comprises a tub, a basket, a spray arm, a water cup 2000, a circulating pump 3000 and a drain pump 4000.

[0048] The tub forms a washing cavity (i.e. the internal space of the tub) and an opening communicating with the washing cavity, and a door body of the dishwasher is movable between an open position and a closed position, the opening being closed when the door body moves to the closed position and being opened when the door body moves to the open position.

[0049] The basket is slidably movable in and out of the washing cavity, thereby facilitating loading and unloading of tableware, which is understood as articles that can be cleaned by the dishwasher, including but not limited to bowls, dishes, cups, pots, knives, forks and chopsticks.

[0050] The spray arm can be located above the basket or below the basket, and the spray arm rotates synchronously when spraying water flow, the water flow being sprayed towards the tableware to wash and clean the tableware. Generally, in a direction from top to bottom, the spray arm comprises an upper spray arm and a lower spray arm, or an upper spray arm, a middle spray arm and a lower spray arm, the upper spray arm spraying water flow downward to wash the tableware, the middle spray arm and the lower spray arm spraying water flow upward to wash the tableware. Of course, in some embodiments, fixed nozzles can also be provided to spray water flow at a specific angle.

[0051] The water flow sprayed from the spray arm needs to be realized by the working of the circulating pump 3000, the circulating pump 3000 is connected with the water cup 2000, the water cup 2000 is arranged at the bottom of the inner container for temporarily storing water, the circulating pump 3000 sucks the water in the water cup 2000 to deliver to the spray arm, the water flow is sprayed from the spray arm and then falls back to the bottom of the inner container to flow into the water cup 2000 again, and continues to be sucked by the circulating pump 3000, so as to form a washing cycle to realize the washing and cleaning of the tableware. The drain pump 4000 is connected with the water cup 2000, after the washing cycle is completed, the drain pump 4000 is started, and the water in the water cup 2000 is discharged outward.

[0052] After the dishwasher discharges water through the drain pump 4000, drying is needed, and the air in the inner container needs to be sucked out during drying, and the embodiment is performed by the blowing assembly 1000, the blowing assembly 1000 includes an air duct 1100, a fan wheel 1200 and a motor 1300, the air duct 1100 is provided with an air inlet 1110 and an air outlet 1120, the air inlet 1110 is communicated with the inner container, the fan wheel 1200 is located in the inside of the air duct 1100, the motor 1300 is connected with the fan wheel 1200, the motor 1300 can drive the fan wheel 1200 to rotate when the motor 1300 is started, the fan wheel 1200 rotates to drive the air in the inner container to flow into the inside of the air duct 1100 in the form of air flow through the air inlet 1110, the air flow flows along the air duct 1100 and flows through the fan wheel 1200, and finally is discharged from the air outlet 1120, in the embodiment, the motor 1300 is arranged outside the air duct 1100, the air flow flowing through the fan wheel 1200 will not contact the motor 1300, and the moisture in the air flow will not cause the motor 1300 to be corroded or short-circuited, so that the motor 1300 is effectively avoided from being damaged, and the service life of the motor 1300 is prolonged.

[0053] It can be understood that the air flow discharged from the air outlet 1120 can be directly discharged to the outside, or the air flow discharged from the air outlet 1120 can be input into the inside of the dishwasher to form an inner circulation. The inside of the dishwasher includes but is not limited to the inner container, the water cup 2000, the circulating pump 3000, the drain pump 4000 and the spray arm, for example, the inner circulation drying, the inside of the dishwasher still has a high temperature after the washing cycle is completed, the moisture in the air flow will continuously condense (such as contacting the wall of the inner container) in the process of the inner circulation, the condensed water flows to the water cup 2000, so that the drying is realized. Alternatively, a separate heating device can be arranged for the air flow in the inner circulation to heat or a dehumidifying device is arranged to dehumidify, which is more helpful for drying.

[0054] Since the fan wheel 1200 is arranged inside the air duct 1100 and the motor 1300 is arranged outside the air duct 1100, in order to facilitate the motor 1300 to drive the fan wheel 1200 to rotate, in combination with the fact that the motor 1300 is arranged outside the air duct 1100, Figure 8As shown, in some embodiments, the blowing assembly 1000 further comprises a driving shaft 1310, one end of the driving shaft 1310 is connected with the wind wheel 1200, the other end of the driving shaft 1310 penetrates the air duct 1100 to connect the motor 1300, that is, a part of the driving shaft 1310 is located inside the air duct 1100, another part of the driving shaft 1310 is located outside the air duct 1100, the driving shaft 1310 is in a state of penetrating the wall of the air duct 1100, so that the direct driving of the motor 1300 to the wind wheel 1200 can be realized, and the structural complexity is reduced. Generally, the motor 1300 comprises a rotor and a stator, the driving shaft 1310 is connected with the rotor, the rotation of the rotor realizes the rotation of the driving shaft 1310, so as to drive the wind wheel 1200 to rotate inside the air duct 1100.

[0055] In combination Figure 8 As shown, in some embodiments, the projection of at least part of the air inlet 1110 in the air inlet direction is located between the wind wheel 1200 and the motor 1300, which is beneficial to improve the efficiency of air flow.

[0056] In order to prevent air leakage between the penetration of the air duct 1100 and the driving shaft 1310, in some embodiments, a sealing mechanism (not shown in the figure) is arranged between the penetration of the air duct 1100 and the driving shaft 1310, that is, the wall of the air duct 1100 has a penetration hole, the penetration hole constitutes the penetration of the air duct 1100, the driving shaft 1310 penetrates the penetration hole, and a sealing mechanism is arranged between the penetration hole and the driving shaft 1310, which prevents air leakage at this position.

[0057] For example, the sealing mechanism comprises an O-shaped sealing ring, the O-shaped sealing ring is arranged at the penetration hole, the driving shaft 1310 needs to penetrate the O-shaped sealing ring, and the O-shaped sealing ring fills the gap between the driving shaft 1310 and the penetration hole through elastic deformation, so as to realize sealing.

[0058] For another example, the sealing mechanism comprises a dynamic ring and a static ring, the static ring is arranged at the penetration hole, the dynamic ring is sleeved on the driving shaft 1310 and is fixed relative to the driving shaft 1310, the driving shaft 1310 penetrates the static ring and makes the dynamic ring embedded in the static ring, the dynamic ring shell rotates relative to the static ring, and sealing is realized through the cooperation of the dynamic ring and the static ring.

[0059] Of course, the sealing mechanism can also be selected from other types of structures, which are not described here.

[0060] Optionally, in some embodiments, a support (not shown in the figure) is arranged inside the air duct 1100, which supports the drive shaft 1310, so that the rotation of the wind wheel 1200 is more stable. As known from the above, the motor 1300 comprises a stator and a rotor, and the rotor is connected with the drive shaft 1310, that is, the part of the drive shaft 1310 located outside the air duct 1100 is supported by the stator. By arranging the support inside the air duct 1100, the part of the drive shaft 1310 located inside the air duct 1100 can be supported, and thus the rotation stability of the drive shaft 1310 can be improved, especially when the drive shaft 1310 extends deeply into the air duct 1100, which is more helpful for the stable rotation of the wind wheel 1200.

[0061] The wind wheel 1200 can be an axial flow wind wheel, a centrifugal wind wheel, or a cross flow wind wheel, which will be described in combination with Figure 8 As shown in the figure, in the embodiment, the wind wheel 1200 is an axial flow wind wheel, that is, the airflow enters along the axial direction and is discharged along the axial direction. The axial flow wind wheel structure is relatively simple, does not need a volute, can generate a larger air volume, and is more helpful for the realization of drying, and occupies a smaller volume under the same air volume compared with the centrifugal wind wheel and the cross flow wind wheel.

[0062] In combination with Figure 8 As shown in the figure, in some embodiments, on the basis that the wind wheel 1200 is an axial flow wind wheel, the rotation axis of the wind wheel 1200 passes through the air outlet 1120, that is, at least part of the wind wheel 1200 can be seen through the air outlet 1120, so that the airflow resistance can be reduced. For example, along the axial direction of the wind wheel 1200, the center of rotation of the wind wheel 1200 and the center of the air outlet 1120 can be designed as coaxial arrangement.

[0063] In combination with Figures 5 to 8 As shown in the figure, in some embodiments, the air outlet direction of the air outlet 1120 and the air inlet direction of the air inlet 1110 are intersected, so that when the wind wheel 1200 is an axial flow wind wheel, the motor 1300 is conveniently arranged, and the whole blow drying assembly 1000 can be made more flat, and the flat blow drying assembly 1000 is convenient to install on the side of the inner container.

[0064] In combination with Figures 5 to 8 As shown in the figure, in some embodiments, the blow drying assembly 1000 further comprises a mounting seat 1400, which is arranged outside the air duct 1100, and the motor 1300 is arranged in the mounting seat 1400, so that the motor 1300 is fixed relative to the air duct 1100, and the blow drying assembly 1000 is assembled into a module, which is helpful for improving the production efficiency of the whole dishwasher. Generally, the blow drying assembly 1000 is installed on the side of the inner container, and the air duct 1100 is a relatively large part in the blow drying assembly 1000. The air duct 1100 is fixed to the inner container, and the installation of the blow drying assembly 1000 can be realized.

[0065] The mounting seat 1400 can be provided on the air duct 1100 in various ways. For example, the mounting seat 1400 and the air duct 1100 are respectively manufactured as separate components, and then connected and fixed together by connection means such as screws, welding, or the like. Alternatively, the air duct 1100 and the mounting seat 1400 can be integrally formed, which is advantageous in simplifying the structure and reducing assembly errors, that is, at least part of the air duct 1100 can be simultaneously formed with at least part of the mounting seat 1400 during manufacturing. For example, the air duct 1100 includes two half structures that are welded together, one of the two half structures of the air duct 1100 is formed with the mounting seat 1400, or one of the two half structures of the air duct 1100 is formed with part of the mounting seat 1400, the other of the two half structures of the air duct 1100 is formed with the remaining part of the mounting seat 1400, and the two half structures of the air duct 1100 are welded together to form the mounting seat 1400.

[0066] In combination Figures 5 to 8 As shown, in some embodiments, the motor 1300 is arranged in the mounting seat 1400, which improves the stability of the motor 1300. For example, the mounting seat 1400 is integrally formed, and the motor 1300 is embedded in the mounting seat 1400 during installation, so that the motor 1300 is wrapped by the mounting seat 1400. Alternatively, the mounting seat 1400 is formed by splicing at least two parts, and the motor 1300 is wrapped by the mounting seat 1400 during splicing.

[0067] In combination Figures 5 to 8 As shown, in some embodiments, the mounting seat 1400 is open on the side away from the air duct 1100. The motor 1300 generates heat during operation, and the open side of the mounting seat 1400 away from the air duct 1100 is advantageous in dissipating heat of the motor 1300 and avoiding heat accumulation that affects the operation of the motor 1300.

[0068] In combination Figures 8 to 9 As shown, in some embodiments, the mounting seat 1400 is provided with a gap 1410, and the drive shaft 1310 is exposed from the gap 1410. The gap 1410 further improves the heat dissipation capacity of the motor 1300. In the case that the mounting seat 1400 is open on the side away from the air duct 1100, heat can be dissipated from both ends of the motor 1300 in the axial direction by the gap 1410. Alternatively, the hair dryer assembly 1000 further includes a second fan wheel 1210 arranged outside the air duct 1100 and located between the air duct 1100 and the motor 1300. The motor 1300 is adapted to simultaneously drive the fan wheel 1200 and the second fan wheel 1210 to rotate. The second fan wheel 1210 is fixed on the drive shaft 1310, and the second fan wheel 1200 can drive airflow to flow when the motor 1300 operates. The airflow exchanges heat with the outside through the gap 1410, thereby improving the heat dissipation effect.

[0069] In combination Figure 10 As shown in some embodiments, the air duct 1100 is also provided with a second air inlet 1130, which is open towards the motor 1300. When the fan wheel 1200 rotates, the airflow enters the inside of the air duct 1100 from the outside through the second air inlet 1130. Since the second air inlet 1130 is open towards the motor 1300, the airflow can flow through the motor 1300, thereby achieving heat dissipation of the motor 1300.

[0070] The second aspect of the present application discloses a dishwasher, which comprises the above-mentioned air blowing assembly 1000. The air blowing assembly 1000 comprises an air duct 1100, a fan wheel 1200 and a motor 1300. The air duct 1100 is provided with an air inlet 1110 and an air outlet 1120. The air inlet 1110 is adapted to communicate with the inner container of the dishwasher. The fan wheel 1200 is arranged inside the air duct 1100. The fan wheel 1200 is used to drive the airflow to flow into the air inlet 1110 and flow out of the air outlet 1120 when rotating. The motor 1300 is arranged outside the air duct 1100. The motor 1300 is connected with the fan wheel 1200 and is used to drive the fan wheel 1200 to rotate. By arranging the motor 1300 outside the air duct 1100, the moisture or other impurities in the airflow will not contact the motor 1300 when the airflow flows along the air duct 1100. Thus, the damage of the motor 1300 is avoided, and the normal operation of the air blowing assembly 1000 is ensured. It can be understood that the air blowing assembly 1000 of the dishwasher of the present embodiment adopts the technical solutions of the above-mentioned embodiments, and thus at least has the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0071] In combination Figures 1 to 4 As shown in some embodiments, the inner container 5000 is provided with an air outlet 5100 and an air return 5200. The air blowing assembly 1000 further comprises an extension channel 1500, one end of which communicates with the air outlet 5100, and the other end of which communicates with the air inlet 1110. The air outlet 1120 and the air return 5200 of the inner container 5000 communicate with each other. The fan wheel 1200 drives the gas in the inner container 5000 to flow out of the air outlet 5100 and flow back to the inner container 5000 through the air return 5200. Thus, the internal circulation drying is achieved. By arranging the extension channel 1500, the position arrangement of the air blowing assembly 1000 is more convenient. When the dishwasher is in the drying stage, the motor 1300 drives the fan wheel 1200 to rotate. The air in the inner container enters the air duct 1100 from the air inlet 1110 and flows out of the air outlet 1120 to re-enter the inner container. Thus, the internal circulation is formed. In the process of internal circulation, the moisture in the airflow condenses into condensed water on the wall of the inner container. The moisture content in the airflow gradually decreases, thereby achieving the internal circulation drying.

[0072] In combination Figures 1 to 3As shown, in some embodiments, the dishwasher further comprises a return air duct 5300, the return air duct 5300 being connected to the air outlet 1120 of the air blowing assembly 1000 and the return air port 5200 of the inner container 5000 respectively, the return air port 5200 being provided with a movable air deflector 5400, through the arrangement of the air deflector 5400, the air flow range entering the inside of the inner container 5000 is increased, which is more conducive to the drying process.

[0073] In combination Figure 4 As shown, in some embodiments, the dishwasher further comprises a water cup 2000, a circulation pump 3000 and a distribution valve 6000, the water cup 2000 and the distribution valve 6000 being connected, the circulation pump 3000 and the distribution valve 6000 being connected, the air outlet 1120 and the distribution valve 6000 being connected, the distribution valve 6000 being adapted to control at least one of the water cup 2000 and the circulation pump 3000 to communicate with the air outlet 1120.

[0074] When the distribution valve 6000 controls the water cup 2000 to communicate with the air outlet 1120, the air flow discharged from the air outlet 1120 enters the water cup 2000, thereby realizing the drying of the water cup 2000. When the distribution valve 6000 controls the circulation pump 3000 to communicate with the air outlet 1120, the air flow discharged from the air outlet 1120 enters the circulation pump 3000, thereby realizing the drying of the circulation pump 3000. Since the circulation pump 3000 of the dishwasher is connected to the spray arm, the air flow eventually enters the spray arm and is sprayed from the spray arm to re-enter the inner container 5000, thereby realizing the drying of the spray arm and the drying of the inner container 5000 and the tableware placed in the inner container 5000.
