The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring to fig. 1 to 25, an air extracting apparatus 100 of a dishwasher according to an embodiment of the present invention includes a housing 10 (see fig. 17) and a driving mechanism 20 (see fig. 18).

The housing 10 is provided with an air inlet 11, an air outlet 12 and an air duct 13 (see fig. 5). The air duct 13 communicates with the air inlet 11 and the air outlet 12.

The drive mechanism 20 is mounted on the housing 10. The drive mechanism 20 includes an air extracting member 21 located within the housing 10. The driving mechanism 20 is used for driving the air extracting part 21 to rotate so that the air flow in the inner container 700 of the dishwasher is guided into the air duct 13 by the air inlet 11 and is discharged out of the inner container 700 from the air outlet 12.

In the air exhausting device 100 of the dishwasher of the present invention, the air in the inner container 700 can be guided into the air duct 13 by the driving mechanism 20 through the air exhausting member 21, and then exhausted to the outside of the dishwasher 1000 through the air outlet 11, such that the air flow of the inner container 700 of the dishwasher can be accelerated to flow, thereby promoting the drying speed of the dishwasher 1000, and further improving the drying performance of the dishwasher 1000.

In one embodiment, the air duct 13 includes a condensation air duct 131 (see fig. 5 and 19) communicating the air inlet 11 and the air outlet 12, and the condensation air duct 131 is a winding air duct.

Thus, the circuitous condensation air duct 131 can lengthen the stroke of the air flow in the air duct 13, which is beneficial to fully condensing and drying the hot moisture in the inner container 700.

Specifically, the condensation duct 131 may be used for condensing hot moisture entering the condensation duct 13 from the dishwasher 1000, for example, during the operation of the dishwasher 1000, the dishwasher 1000 includes a plurality of operation stages, such as pre-washing, main washing, and drying stages, and during the washing stage before drying, the dishwasher 1000 needs to spray water onto the washing implement to clean food residues on the washing implement.

Therefore, the inner surface of the inner container 700 accumulates much liquid water before drying. During the drying process of the dishwasher 1000, the liquid water in the inner container 700 is heated to evaporate and form hot moisture. At this time, when the ventilator 100 of the dishwasher is in an operating state, the ventilator 100 of the dishwasher can guide the hot moisture in the inner container 700 into the condensation air duct 131 for condensing the hot moisture from the air inlet 11, and exchange heat with the outside in the condensation air duct 131 to condense the moisture in the hot moisture.

In the embodiment of the present invention, the whole air duct 13 has a condensation function, and the condensation air duct 131 is a main condensation part of the dishwasher exhaust device 100 for condensing hot moisture. When the driving mechanism 20 is in an operating state, hot and humid air is guided into the air duct 13 from the air extracting part 21 through the air inlet 11, is condensed to a certain temperature in the air duct 13, and then forms a drier air flow. Most of the water vapor in the hot moisture is condensed into liquid water after passing through the air duct 13.

In the embodiment of the invention, when the driving mechanism 20 drives the air extracting part 21 to rotate, hot and wet air can enter the casing 10 from the vertical direction of the air extracting part 21 and then enter the condensation air duct 131 along the tangential direction of the air extracting part 21, so that the friction resistance between the hot and wet air flow entering the condensation air duct 131 and the inner wall of the condensation air duct 131 is small, and the noise generated when the air extracting device 100 of the dishwasher works can be reduced.

In one embodiment, the condensation duct 131 is substantially S-shaped and circuitous.

So, condensation wind channel 131' S stroke is longer, and condensation area is great to can guarantee the effect of condensation, and the mode that sets up of S type makes the shared space that sets up in condensation wind channel 131 less, and then the miniaturization of the updraft ventilator 100 of the dish washer of being convenient for.

It is understood that in other embodiments, the condensation duct 131 may be provided in other suitable shapes. Therefore, it should be noted that the shape of the condensation duct 131 is not limited, and may be appropriately set according to specific situations.

In one embodiment, the housing 10 defines an accommodating space 132 (see fig. 5 and 19), and the air duct 13 includes a first connecting air duct 133. The air extracting piece 21 is positioned in the accommodating space 132. The first connecting duct 133 connects the air inlet 11 and the accommodating space 132. The accommodating space 132 communicates with the first connecting duct 133 and the condensing duct 131.

Specifically, when the driving mechanism 20 drives the exhausting member 21 to rotate, the hot and humid air flow in the inner container 700 enters through the air inlet 11, then enters into the first connecting air duct 133, and then enters into the condensing air duct 13 along the accommodating space 132.

The first connecting duct 133 may be provided to increase a distance between the driving mechanism 20 and the intake vent 11, so that the driving mechanism 20 may be less adversely affected by moisture during washing of the dishwasher.

In one embodiment, the exhaust member 21 is positioned higher than the air inlet 11.

So, because the position of convulsions piece 21 is higher than the position of air intake 11 for updraft ventilator 100 of dish washer forms the pipeline design that upwards induced drafts, and the hydroenergy that sprays updraft ventilator 100 of dish washer in the washing process of dish washer 1000 can be through 11 backward flow inner bags 700 of air intake, has avoided producing ponding in updraft ventilator 100 of dish washer.

In the embodiment of the present invention, when the driving mechanism 20 drives the exhausting member 21 to rotate, the hot and humid air enters the first connecting duct 133 from the vertical direction of the exhausting member 21, flows upward along the first connecting duct 133 and is sucked into the accommodating space 132, and then enters the condensing duct 131 along the tangential direction of the exhausting member 21.

In one embodiment, the air chute 13 includes a second connecting air chute 134. The second connecting air channel 134 is connected to the condensing air channel 131 and the air outlet 12. The first connecting duct 133 is substantially parallel to the second connecting duct 134.

Thus, the hot moisture is condensed by the condensing duct 131, separated from the condensed water vapor, and then enters the second connecting duct 134 and is discharged from the air outlet 12. Also, the provision of the second connecting duct 134 may further increase the effective condensation area of the exhaust device 100 of the dishwasher to ensure sufficient condensation of hot moisture. The first connecting duct 133 is disposed in parallel with the second connecting duct 134 such that the flow direction of the hot and humid air in the first connecting duct 133 is the same as or opposite to the flow direction of the hot and humid air in the second connecting duct 134, thereby promoting the flow rate of the hot and humid air by properly positioning the air inlets 11 and the air outlets 12 on the air extracting device 100 of the dishwasher.

For example, in the embodiment of the present invention, the first connecting air duct 133 and the second connecting air duct 134 are arranged in parallel, and the flow direction of the hot moisture in the first connecting air duct 133 is the same as the flow direction of the hot moisture in the second connecting air duct 134, and both of them flow upward. In the first connecting duct 133, the hot moisture flows from bottom to top toward the accommodating space 132 under the action of the suction force formed by the air extracting member 21, and in the second connecting duct 134, the mass of the condensed hot air flow becomes lighter, and the hot air flow with lower density naturally rises along the second connecting duct 134 and is discharged from the air outlet 12.

In one embodiment, the bottom of the housing 10 is opened with a first water outlet 14 (see fig. 4 and 19) communicated with the condensation duct 131.

In this way, the water condensed from the hot moisture by the condensing duct 131 is merged to form a water flow, and can be discharged along the first water outlet 14 under the action of gravity. In the embodiment of the present invention, the first water outlet 14 is communicated with the inner container 700, that is, the condensed water formed in the condensed air duct 131 flows back to the inner container 700 through the first water outlet 14.

In one embodiment, the housing 10 includes a plurality of rib locations 15 (see fig. 3 and 19) that form condensation ducts 131. Each rib 15 is inclined towards the bottom of the housing 10. Like this, form condensation wind channel 131 through a plurality of muscle positions 15, such arrangement simple structure and easy realization. Moreover, the rib position 15 can be used for guiding the flowing direction of the condensed water condensed from the hot moisture in the condensation air duct 131. Meanwhile, the rib positions 15 are inclined towards the bottom, so that condensed water condensed in the condensation air duct 131 can be easily guided to the first water outlet 14 arranged at the bottom of the shell 10 along the direction of the rib positions 15.

In one embodiment, the extractor air device 100 of the dishwasher includes a water guide 30 (see fig. 18) located within the housing 10 and connected to the air inlet 11. The water guide 30 includes a slope 31 facing the intake vent 11 (see fig. 20).

Thus, the water guide portion 30 can effectively prevent water accumulation from occurring in the air duct 13, thereby ensuring smooth flowing of the air flow in the air duct 13.

In one embodiment, the bottom of the housing 10 is opened with a second water outlet 141 (see fig. 4 and 5) communicated with the air duct 13. The plurality of rib positions 15 include a first rib position 151 and a second rib position 152 located at the bottom of the housing 10. The first rib portions 151 and the second rib portions 152 are partially overlapped at intervals to form the second water outlet 141. The second water outlet 141 is located on the lee side of the air duct 13.

Thus, the second water outlet 141 on the lee side of the air duct 13 can effectively prevent the moisture generated by the operation of the air exhaust device 100 of the dishwasher from leaking out through the second water outlet 141.

In the embodiment of the present invention, specifically, the second water outlet 141 is located on the lee side of the condensation air duct 131. The second water outlet 141 is communicated with the air duct 13 and the first water outlet 14, and the first water outlet 14 is communicated with the inner container 700. Thus, the airflow generated by the ventilator 100 during operation can be substantially discharged from the air outlet 12 through the second connecting duct 134, and the condensed water flow formed in the duct 13, especially the condensed air duct 131, substantially flows into the inner container 700 through the second water outlet 141 and the first water outlet 14, thereby achieving water circulation.

In one embodiment, the casing 10 is opened with an auxiliary air outlet 121 (see fig. 5 and 17) communicated with the condensation air duct 131. The size of the auxiliary outlet 121 is smaller than that of the outlet 12. The auxiliary air outlet 121 is located between the air inlet 11 and the condensing air duct 131.

Thus, the auxiliary outlet 121 with a smaller size can be used as an auxiliary outlet for airflow to promote smooth flow of the airflow, for example, when the air exhaust device 100 of the dishwasher is operated, and the amount of hot moisture entering the condensation air duct 131 is too large and cannot be discharged from the air outlet 121 in time, the auxiliary outlet 121 can allow excessive airflow to be partially and directly discharged from the auxiliary outlet 121, so as to prevent the smooth flow of the airflow from being obstructed by too large steam pressure in the housing 10, thereby ensuring the drying effect of the dishwasher 1000.

In one embodiment, the extractor air device 100 of the dishwasher includes a baffle assembly 40 (see FIGS. 4, 6, and 21). The bottom of the housing 10 is opened with a water storage chamber 50 (see fig. 4) and a third water outlet 142 (see fig. 6). The water storage chamber 50 is communicated with the air duct 13 and the third water outlet 142. The damper assembly 40 includes a damper 41 disposed in the water storage chamber 50. The flapper 41 is movable between a first position in which the flapper 41 seals the third water outlet 142, and a second position in which the flapper 41 opens the third water outlet 142.

Thus, when the baffle 41 seals the third water outlet 142, moisture leakage can be prevented, and when the baffle 41 opens the third water outlet 142, the condensed water in the water storage chamber 50 can be discharged out of the ventilator 100 of the dishwasher.

In the embodiment of the present invention, specifically, the water storage chamber 50 communicates with the condensation duct 131. The water storage chamber 50 is connected to the first outlet 14 and the second outlet 141. When the ventilator 100 of the dishwasher is in an operating state, the hot moisture enters the condensation duct 131 and is condensed to form condensed water, and then the condensed water enters the water storage chamber 50 from the second water outlet 141 for storage, and the baffle assembly 40 makes the baffle 41 be in the first position by its own gravity to seal the third water outlet 142. When the condensed water in the water storage chamber 50 is stored to a certain amount, the baffle 41 moves from the first position to the second position, so that the condensed water in the water storage chamber 50 is discharged through the third water outlet 142 and enters the inner container 700 through the first water outlet 14.

In one embodiment, the density of the baffle 41 is less than the density of water.

Thus, when the condensed water stored in the water storage chamber 50 reaches a certain amount, the baffle 41 can be lifted by the buoyancy of the water and automatically moves from the first position to the second position, so as to open the third water outlet 142.

Specifically, the baffle 41 may be a plastic baffle, so that the plastic baffle is common and the machining and forming are easy to achieve.

In one embodiment, the baffle 41 is a hollow structure. Thus, an air cavity is formed in the baffle 41 of the hollow structure. When the amount of the condensed water stored in the water storage chamber 50 reaches a certain amount, the baffle 41 can also automatically move from the first position to the second position, so as to open the third water outlet 142.

In one embodiment, the baffle assembly 40 includes a connecting member 42 and a limiting member 43. The connecting member 42 connects the baffle plate 41 and the restricting member 43. The connecting member 42 passes through the third water outlet 142. The restricting member 43 serves to restrict the distance that the shutter 41 moves from the first position.

Specifically, when the condensed water in the water storage chamber 50 is stored to a certain amount, the baffle plate assembly 40 makes the baffle plate 41 automatically move from the first position to the second position under the buoyancy of the water, so as to open the third water outlet 142, and at the same time, when the limiting member 43 abuts against the outer wall of the water storage chamber 50, the baffle plate 41 stops moving.

In this way, the restriction member 43 can control the amount of water discharged from the water storage chamber 50 by controlling the movement of the baffle plate 41, and can prevent the baffle plate 41 from moving out of position under the buoyancy of water.

In one embodiment, the housing 10 includes a first cover 16 and a second cover 17 (see fig. 19 and 20), the first cover 16 and the second cover 17 are disposed opposite to each other, the first cover 16 and the second cover 17 are connected to form the air duct 13, the air inlet 11 is disposed on the first cover 16, and the air outlet 12 is disposed on the second cover 17.

Thus, the first and second covers 16 and 17 are connected to form the housing 10 to facilitate assembly and disassembly of the exhaust fan assembly 100 of the dishwasher and to provide convenience for regular cleaning and maintenance of the exhaust fan assembly 100 of the dishwasher. Further, the auxiliary air outlet 121 is also opened on the second cover plate 17.

In the present example, a plurality of bead sites 15 are provided on the inner surfaces of the first cover 16 and the second cover 17. The plurality of rib positions 15 are connected to form a condensation air duct 131.

In the embodiment of the present invention, the first connecting duct 133 and the second connecting duct 134 are formed by connecting the first cover 16 and the second cover 17.

In one embodiment, the drive mechanism 20 includes a body 22 and an output shaft 23 rotatably coupled to the body 22.
