Referring to fig. 1 to 19, a dishwasher 100 according to an embodiment of the present invention includes a tub 10, an air intake device 20, an air exhaust device 30, a door assembly 40, and a controller 44.

The inner container 10 is opened with an air inlet 111. The door assembly 40 is rotatably connected to the inner container 10, and the door assembly 40 is provided with an air outlet 41 communicated with the air inlet 111. The intake device 20 is mounted on the intake port 111. An air extraction device 40 is mounted on the air outlet 41.

Controller 44 connects air inlet unit 20 and updraft ventilator 30, and controller 44 is arranged in controlling updraft ventilator 30 to open in order to follow inner bag 10 convulsions through gas outlet 41 in the dry stage after the washing stage, and after updraft ventilator 30 opened the preset time, controller 44 was used for controlling air inlet unit 20 to open in order to supply air to inner bag 10 through air inlet 111.

Therefore, in the dishwasher 100, the controller 44 firstly opens the air draft device 30 to draw air from the inner container 10 to dry the inner container 10 by using the higher residual heat of the washed inner container 10, and after the preset time, the temperature of the inner container 10 is decreased, and then the air inlet device 20 is opened to supply air to the inner container 10, so that the air draft device 30 and the air inlet device 20 jointly enhance the air flow of the inner container 10, and the drying performance of the dishwasher 100 is ensured.

In particular, the dishwasher 100 according to the embodiment of the present invention may be applied to a built-in dishwasher. The embedded dish washer can be embedded into the space of the kitchen cabinet, so that the kitchen cabinet is tidy. In an example of the present invention, the air extractor 30 is mounted in the door assembly 40. Therefore, when the dishwasher 100 is embedded in a kitchen cabinet, the front of the door assembly 40 is exposed to the kitchen cabinet, heat exchange with the outside is maximized, the condensation rate of moisture in hot moisture in the air extracting device 30 is accelerated, and the condensed water can be attached to the inside of the air extracting device 30.

The inner container 10 includes a side plate 11. The side plate 11 is opened with an air inlet 111. In the present example, the side panel 11 may serve as a right side panel of the inner tub 10 when the dishwasher 100 is built in a counter.

In addition, in the present example, referring to fig. 3, the controller 44 is also installed in the door assembly 40, which facilitates heat dissipation of the controller 44 and ensures a life span of the controller 44.

In one example, the washing stage can be a rinsing stage of the dishwasher 100. After the rinsing stage is finished, the residual temperature of the inner container 10 is high (for example, about 70 ℃), so that the inner container can be dried by using the high residual temperature, and the amount of generated steam is large. At this point, the controller 44 controls the air extraction device 30 to be turned on to extract moisture from the liner 10.

After the preset time, the temperature of the inner container 10 is decreased (to about 45 degrees as follows), at this time, the controller 44 controls the air inlet device 20 to be opened, and under the condition that the air draft device 30 and the air inlet device 20 are opened, on one hand, the air inlet device 20 enhances the airflow flowing of the inner container 10, so that the residual water drops in the inner container 10 are gasified, and on the other hand, the air draft device 30 extracts the gasified water vapor to be discharged out of the dishwasher 100, thereby achieving the purpose of quick drying.

In one embodiment, the predetermined time is 25 minutes.

That is, after controlling the ventilator 30 to turn on for 25 minutes, the controller 44 controls the air intake device 20 to turn on again to perform the drying phase of the dishwasher 100 using the ventilator 30 and the air intake device 20 together.

In an embodiment of the present invention, the dishwasher 100 includes a housing 50. The air intake device 20 is disposed between the inner container 10 and the outer case 50.

In one embodiment, the position of the air inlet 111 is lower than the position of the air outlet 41.

Specifically, during operation of the dishwasher 100, the dishwasher 100 includes a plurality of operation stages, such as washing and drying stages, during which the dishwasher 100 needs to spray water onto the washing implement to clean food residues on the washing implement.

Therefore, before drying, the inner surface of the inner container 10 accumulates more liquid water, especially on the inner surface of the bottom plate of the inner container 10. The position of the air inlet 111 is lower than the position of the air outlet 41, which is beneficial for the air inlet device 20 to blow the air flow to the lower position where the liquid water is easy to accumulate, so that the liquid water is evaporated into gas, the gas rises along the air flow channel and enters the air outlet 41, meanwhile, the rising air flow can also accelerate the evaporation of the liquid water attached to the inner surface of the liner 10, and thus, the drying speed of the liner 10 can be further accelerated.

In one embodiment, the intake device 20 includes a first housing 21 mounted on the inner container 10 and a first driving mechanism 22. The first housing 21 defines a first air inlet 211, a first air outlet 212, and a first air duct 213. The first air duct 213 communicates with the first air inlet 211 and the first air outlet 212. The first air outlet 212 communicates with the air inlet 111. The first drive mechanism 22 is mounted on the first housing 21. The first drive mechanism 22 includes a blower 221 located in the first casing 21. The controller is used for controlling the first driving mechanism 22 to drive the air blowing member 221 to rotate so that the air flow is guided into the first air duct 213 from the first air inlet 211 and guided out to the inner container 10 from the first air outlet 212.

Thus, the external air can be guided into the first casing 21 by the first driving mechanism 22 through the air blowing member 221, and then guided out to the inner container 10 through the first air outlet 212, so that the air flow of the inner container 10 can be accelerated, the drying speed of the dishwasher can be accelerated, the drying performance of the dishwasher 100 can be improved, and energy can be saved.

In one embodiment, the first housing 21 includes a first cover plate 214 and a second cover plate 215. The first cover plate 214 and the second cover plate 215 are disposed opposite to each other. The first cover plate 214 and the second cover plate 215 are connected to form a first air duct 213. The first air inlet 211 and the first air outlet 212 are disposed on the second cover plate 215.

Thus, the first cover plate 214 and the second cover plate 215 are connected to form the first housing 21, which facilitates the assembly and disassembly of the air inlet device 20 of the dishwasher 100, and provides convenience for the regular cleaning and maintenance of the air inlet device 20 of the dishwasher 100.

In one embodiment, the first drive mechanism 22 includes a first body 222 and a first output shaft 223 rotatably coupled to the first body 222. The first housing 21 has a first receiving groove 21a (see fig. 13) and a first shaft hole 21 b. The first body 222 is received in the first receiving groove 21 a. The first output shaft 223 penetrates the first shaft hole 21b and is connected to the blowing member 221.

In this way, the first driving mechanism 22 can drive the first output shaft 223 to rotate so as to drive the air blowing member 221 to rotate, the driving method is simple and reliable, and the first body 222 is accommodated in the first accommodating groove 21a, so that the installation space of the first cover plate 214 is fully utilized, and the air intake device 20 is convenient to miniaturize.

In one embodiment, a paddle mechanism 213a for opening or closing the first air path 213 is provided in the first air path 213.

Specifically, in the embodiment of the present invention, when the first driving mechanism 22 is turned on, the paddle mechanism 213a opens the first air channel 213 to conduct the first air channel 213, so that the air blown by the air blowing component 221 enters the first air channel 213 and can be guided out from the first air outlet 212. When the first driving mechanism 22 stops working, the paddle mechanism 213a closes the first air channel 213 to block the first air channel 213, which can prevent water vapor in the inner container 10 communicated with the air inlet device 20 from entering the air inlet device 20, thereby ensuring the service life of the electrical components in the air inlet device 20.

For example, the paddle mechanism 213a is rotatably provided in the first housing 21. The driving mechanism 213a can open the first air channel 213 by the wind generated when the blowing member 221 is operated, and the first air channel 213 can be closed by the self-gravity of the driving mechanism 213a when the blowing member 221 stops operating.

In one embodiment, the first air inlet 211 is provided with an air inlet mechanism 211 a. The air intake mechanism 211a includes a plurality of air guide bars 211b arranged at intervals. The plurality of air guide strips 211b are distributed in a vortex manner.

In this way, when the first driving mechanism 22 drives the blowing member 221 to rotate, the plurality of air guide strips 211a distributed in a vortex manner can make the airflow rapidly enter the first housing 21 from the first air inlet 211 in a vortex manner, so that the loss of the air inlet amount of the air inlet device 20 of the dishwasher is minimized, and the air inlet amount of the air inlet device 20 of the dishwasher is increased.

Note that, in order to maximize the function of the air guide strips 211a, the direction in which the air guide strips 211a are distributed in a spiral shape coincides with the direction in which the first driving mechanism 22 drives the air blowing member 221 to rotate.

In one embodiment, the intake mechanism 211a includes a stationary ring 211 c. The plurality of air guide strips 211b are connected to the edge of the fixing ring 211c in a spiral radial shape.

In this way, the plurality of air guide strips 211c form a vortex-type radial net structure, so that the air intake mechanism 211a has a larger gap to allow sufficient airflow to enter the first housing 21 through the air intake mechanism 211a, thereby ensuring the intake air volume of the air intake device 20.

In one embodiment, the first air outlet 212 is provided with an air guide mechanism 212a for guiding the airflow in the first air duct 213 to the bottom of the inner container 10. The first driving mechanism 22 is configured to drive the air blowing component 221 to rotate, so that the air flow is guided into the first air duct 213 through the first air inlet 211 and is guided out of the inner container 10 through the first air outlet 212 and the air guiding mechanism 212 a.

Thus, the air guiding mechanism 212a can guide the air flow to the bottom of the inner container 10, so that the inner container 10 can be sufficiently dried.

In the embodiment of the present invention, the air guide mechanism 212a is accommodated in the first air outlet 212. Thus, when the air intake device 20 of the dishwasher is in an operating state, the air guide mechanism 212a accommodated in the first air outlet 212 can sufficiently guide the air flow to the bottom of the inner container 10, so that the bottom of the inner container 10 where the residual water is collected is sufficiently dried.

In one embodiment, the air extraction assembly 30 includes a second housing 31 and a second drive mechanism 32. The second housing 31 is mounted on the door assembly. The second housing 31 defines a second air inlet 311, a second air outlet 312 and a second air duct 313. The second air duct 313 communicates with the second air inlet 311 and the second air outlet 312. The second air inlet 311 is communicated with the air outlet 41. The second drive mechanism 32 is mounted on the second housing 31. The second drive mechanism 32 includes a suction member 321 located within the second housing 31. The controller is used for driving the air extracting member 321 to rotate by the second driving mechanism 32 so as to extract air from the inner container 10.

Like this, the interior hot moisture of inner bag 10 can be derived to the second casing 31 in through convulsions piece 321 by second actuating mechanism 32, and outside is derived to the rethread second wind channel 313 via second air outlet 312, can make the hot humid air current of inner bag 10 accelerate to flow like this to can promote dishwasher's drying rate, and then promote dishwasher 100's drying performance.

In one embodiment, the second air duct 313 includes a condensation air duct 3131 communicating the second air inlet 311 and the second air outlet 312. The condensation air duct 3131 is a winding air duct.

Thus, the winding condensation air duct 3131 can lengthen the stroke of the air flow in the air duct 313, which is beneficial to fully condensing and drying the hot moisture in the inner container 10.

In particular, the condensation duct 3131 may be used to condense hot moisture entering the condensation duct 3131 from the dishwasher 100, and as before, the inner surface of the inner tub 10 may accumulate more liquid water before drying. During the drying process of the dishwasher 100, the liquid water in the tub 10 is heated to evaporate and form hot moisture. When the controller controls the ventilator 30 to be turned on, the ventilator 30 can guide the hot moisture in the inner container 10 into the condensation air duct 3131 for condensing the hot moisture through the second air inlet 311, and exchange heat with the outside in the condensation air duct 3131 to condense the moisture in the hot moisture, so as to promote drying.

In the embodiment of the present invention, the entire second air duct 313 has a condensation function, and the condensation air duct 3131 is a main condensation portion of the hot moisture condensed by the ventilator 30 of the dishwasher. When the second driving mechanism 32 is in an operating state, the hot and humid air is guided into the second air duct 313 from the air extracting element 321 through the second air inlet 311, and is condensed to a certain temperature in the second air duct 313, and then a drier air flow is formed. Most of the water vapor in the hot moisture is condensed into liquid water through the second air channel 313.

In one embodiment, the condensation duct 3131 is substantially S-shaped.

So, condensation wind channel 3131' S stroke is longer, and the 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 of condensation wind channel 3131 less, and then the miniaturization of the updraft ventilator 30 of being convenient for.

It will be appreciated that in other embodiments, the condensation duct 3131 may be provided in other suitable shapes. Therefore, it should be noted that the shape of the condensation duct 3131 is not limited, and may be appropriately set according to specific situations.

In one embodiment, the second housing 31 defines an accommodating space 31a (fig. 17), and the second air duct 313 includes a first connecting air duct 3132. The exhausting member 321 is located in the accommodating space 31 a. The first connecting air passage 3132 connects the second air inlet 311 and the accommodating space 31 a. The accommodating space 31a communicates with the first connecting air duct 3132 and the condensing air duct 3131.

Specifically, when the second driving mechanism 32 drives the exhausting member 321 to rotate, the hot and humid air in the inner container 10 enters through the second air inlet 311, then enters into the first connecting air duct 3132, and then enters into the condensing air duct 3131 along the accommodating space 31 a.

The first connecting air passage 3132 may increase a distance between the second driving mechanism 32 and the second air inlet 311, so that the second driving mechanism 32 may be less adversely affected by moisture during the washing process of the dishwasher 100.

In one embodiment, the exhaust member 321 is positioned higher than the second air inlet 311.

So, because the position of convulsions piece 321 is higher than the position of second air intake 311 for updraft ventilator 30 forms the pipe-line design that upwards induced drafts, and the hydroenergy that sprays into updraft ventilator 30 in the washing process of dishwasher 100 can be through second air intake 311 backward flow inner bag 10, has avoided producing ponding in the updraft ventilator 30 of dishwasher.

In the embodiment of the present invention, when the second driving mechanism 32 drives the exhausting member 321 to rotate, the hot and humid air enters the first connecting air passage 3132 from the vertical direction of the exhausting member 321, flows upwards along the first connecting air passage 3132 and is sucked into the accommodating space 31a, and then enters the condensing air passage 3131 along the tangential direction of the exhausting member 321.

In one embodiment, the second air duct 313 includes a second connecting air duct 3133. The second connecting air duct 3133 connects the condensing air duct 3131 and the second air outlet 312. The first connecting air passage 3132 is substantially parallel to the second connecting air passage 3133.

Thus, the hot moisture is condensed by the condensing air duct 3131, separated from the condensed water vapor, and then enters the second connecting air duct 3133 and is discharged through the second air outlet 312. Also, the second connecting air duct 3133 may further increase an effective condensation area of the exhaust device 30 of the dishwasher to ensure sufficient condensation of hot moisture. The first connecting air passage 3132 is disposed in parallel with the second connecting air passage 3133 such that the flow direction of hot and humid air in the first connecting air passage 3132 is the same as or opposite to the flow direction of hot and humid air in the second connecting air passage 3133, whereby the flow rate of hot and humid air can be promoted by properly positioning the second air inlet 311 and the second air outlet 312 on the air extracting device 30 of the dishwasher.

For example, in the embodiment of the present invention, the first connecting air passage 3132 and the second connecting air passage 3133 are arranged in parallel, and the flow direction of the hot moisture in the first connecting air passage 3132 is the same as the flow direction of the hot moisture in the second connecting air passage 3133, and both of them flow upward. In the first connecting air duct 3132, the hot moisture flows from bottom to top toward the accommodating space 31a under the action of the suction force formed by the exhausting member 321, and in the second connecting air duct 3133, the mass of the condensed hot air flow is reduced, and the hot air flow with lower density naturally rises along the second connecting air duct 3133 and is exhausted from the second air outlet 312.

In one embodiment, the bottom of the second housing 31 is opened with a water outlet 314. The water outlet 314 is communicated with the condensation air duct 3131.

Thus, the water condensed from the hot moisture via the condensing duct 3131 joins to form a water flow, and can be discharged along the water outlet 314 under the action of gravity. In the embodiment of the present invention, the water outlet 314 is communicated with the inner container 10, that is, the condensed water formed in the condensed air duct 3131 flows back to the inner container 10 through the water outlet 314.
