Referring to FIGS. 1 through 7, a fan unit 10 of an embodiment of the present invention is used in a dishwasher 100. The dishwasher 100 includes a bladder 20. The liner 20 is provided with a washing chamber 21. The fan unit 10 includes a cover 11, a fan 12, a humidity detecting device 13, and a controller 14.

The cover 11 is provided with an air passage 111 that communicates with the washing chamber 21 and the outside. The fan 12 is used to establish a flow of air through the duct 111 to ventilate the washing chamber 21. The humidity detecting device 13 is mounted on the cover 11. The humidity detecting device 13 includes a humidity detecting element 131 fixed to the side wall of the air duct 111. The humidity detecting element 131 includes a detecting end 132 located in the air duct 111. The humidity detecting element 131 is for detecting the humidity in the air passage 111 through the detecting end 132. The controller 14 is electrically connected to the humidity detecting element 131 and the fan 12. The controller 14 is for controlling the operating state of the fan 12 in accordance with the humidity.

In the fan device 10 described above, the humidity detecting element 131 can detect the humidity in the air passage 111, so that the controller 14 can control the operation of the fan 12 according to the humidity in the air passage 111 to accelerate the air circulation between the washing chamber 21 and the outside, and further The content of water vapor in the washing chamber 21 can be effectively reduced, so that the generation of odor and the moisture return of the washing chamber 21 of the dishwasher 100 can be avoided.

It should be noted that after the washing of the dishwasher 100 is completed, the controller 14 can be used to control the humidity detecting element 131 to detect the humidity, and control the working state of the fan 12 after the washing of the dishwasher 100 is completed according to the humidity. That is, the dishwasher 100 having the fan unit 10 can control the operation of the fan 12 by the humidity detected by the humidity detecting element 131, thereby causing the washing chamber 21 to circulate air with the outside, thereby reducing the water vapor of the washing chamber 21. content. Wherein, the end of washing of the dishwasher 100 means that the dishwasher 100 has finished the washing process. The washing process generally includes several procedures such as pre-washing, main washing, rinsing and drying, and the washing of the dishwasher 100 generally means that the drying process has ended. . In addition, the humidity in the duct 111 can be regarded as the humidity of the washing chamber 21.

For example, in some examples, after the washing of the dishwasher 100 is finished, the controller 14 controls the humidity detecting element 131 to detect the humidity, and according to the humidity control fan 12, stops the first predetermined time after the washing of the dishwasher 100 is stopped, and then runs the second. The predetermined time, the humidity is inversely related to the first predetermined time, and the humidity is positively correlated with the second predetermined time. It can be understood that when the humidity is relatively small, it is indicated that the water vapor in the dishwasher 100 does not easily condense into water droplets, so that the fan 12 can be controlled to stop for a long time (ie, the first predetermined time is long) and run for a short time (ie, the second The predetermined time is shorter; when the humidity is relatively large, it is indicated that the water vapor in the dishwasher 100 is easily condensed into water droplets, so that the fan 12 can be controlled to stop for a short time (ie, the first predetermined time is short) and run for a long time ( That is, the second predetermined time is longer, thereby removing water vapor in the dishwasher 100, thereby preventing the water vapor from condensing into water droplets.

In certain embodiments, the air duct 111 includes an intake air duct 112 and an air outlet duct 113. The cover 11 is provided with a receiving cavity 114. The fan 12 is located within the accommodating cavity 114. The accommodating chamber 114 communicates with the inlet air duct 112 and the air outlet duct 113.

Thus, when the controller 14 controls the fan 12 to rotate, the hot humid or humid airflow in the washing chamber 21 enters through the inlet air duct 112, and then enters the air outlet duct 113 along the accommodating chamber 114, thus facilitating the fan. 12 runs.

It will be appreciated that the controller 14 can drive the fan 12 to rotate by a drive mechanism (not shown).

In some embodiments, the humidity detecting element 131 is fixed to the side wall 1131 of the air outlet duct 113. The detecting end 132 is located in the air outlet duct 113.

Thus, the humidity detected by the humidity detecting element 131 through the detecting end 132 is close to the humidity in the washing chamber 21, and can be regarded as the humidity in the washing chamber 21, thereby improving the accuracy of the controller 14 controlling the operation of the fan 12 according to the humidity. degree. In addition, since the air outlet duct 113 is further outward with respect to the air inlet duct 112, the installation of the humidity detecting device 13 is facilitated.

Of course, it can be understood that the detection end 132 can also be located within the inlet air duct 112.

In the example shown in Fig. 1, the flow direction m of the airflow in the outlet duct 113 is downward (which may be vertically downward). The detection end 132 is disposed substantially perpendicular to the flow direction m of the air flow. The moisture flowing downward in this way can flow down under the action of gravity in the air outlet duct 113, so that the water entrained by the moisture does not easily remain on the detecting end 132, thereby effectively preventing the water from remaining on the detecting end 132. The accuracy detected by the humidity detecting element 131 is affected.

In some embodiments, the detection end 132 is closer to the outlet of the accommodating cavity 114 relative to the outlet 1132 of the outlet plenum 113.

In this way, the accuracy of the detection by the detecting end 132 can be improved.

In some embodiments, the cover 11 is formed with a first positioning and securing structure 15. The humidity detecting device 13 includes a second positioning fixing structure 133. The humidity detecting element 131 is fixed to the second positioning fixing structure 133. The humidity detecting element 131 is passed through the first positioning fixing structure 15 such that the detecting end 132 is located in the air duct 111. The first positioning fixing structure 15 cooperates with the second positioning fixing structure 133 to fix the humidity detecting element 131 on the side wall of the air duct 111.

Thus, the first positioning fixing structure 15 and the second positioning fixing structure 133 are fixedly fixed, so that the humidity detecting element 131 is stably fixed on the side wall of the air duct 111, thereby ensuring that the detecting end 132 does not flow due to the air passage 111. The impact produces a positional shift.

It should be noted that the depth at which the detecting end 132 extends into the air duct 111 can be set according to specific conditions.

In some embodiments, the first positioning fixture 15 includes a card structure 151 that protrudes from the outer surface of the sidewall of the air duct 111. The second positioning fixing structure 133 includes a fixing plate 134. The humidity detecting element 131 is fixed to the fixing plate 134. The card structure 151 is snapped onto the fixing plate 134 such that the humidity detecting element 131 is fixed to the side wall of the air duct 111.

Thus, the manner in which the card structure 151 is disposed on the fixing plate 134 facilitates the mounting and dismounting of the humidity detecting device 13. For example, when the sensitivity of the humidity detecting element 131 is lowered, when the humidity detecting element 131 is replaced, the card structure 151 can be directly detached from the fixing plate 134 to remove the humidity detecting element 131 whose sensitivity is lowered, and can be removed again. The new humidity detecting element 131 is mounted on the side wall of the duct 111 by the card structure 151 being attached to the fixing plate 134, thereby completing the replacement of the humidity detecting element 131.

It can be understood that the humidity detecting element 131 can also be fixed to the fixing plate 134 in a detachable manner.

In some embodiments, the clip structure 151 includes two clips 152 that are spaced apart. Two card members 152 are respectively attached to both sides of the fixing plate 134 to fix the humidity detecting element 131 on the side wall of the air duct 111. The humidity detecting element 131 is located between the two card members 152.

Thus, the manner in which the two card members 152 are engaged with the card member 152 can further improve the stability of the humidity detecting element 131 fixed to the side wall of the air duct 111.

In some embodiments, the first positioning fixture 15 includes a mating end 153 that extends outwardly from a sidewall of the air duct 111. The first positioning fixing structure 15 defines a matching groove 154 extending through the mating end 153 and the side wall of the air duct 111. The humidity detecting element 131 is threaded through the mating slot 154 such that the detecting end 132 is located within the air duct 111. A portion of the humidity detecting element 131 is housed in the fitting groove 154. The mating end 153 is located between the two clips 152.

Thus, under the guiding action of the fitting groove 154, the humidity detecting element 131 can smoothly pass through the fitting groove 154 such that the detecting end 132 is located in the air duct 111. In addition, the arrangement of the mating end 153 can also improve the stability of the humidity detecting element 131 fixed to the side wall of the duct 111.

In certain embodiments, the humidity detecting device 13 includes a cover 135. One end of the cover 135 is fixed to the second positioning fixing structure 133 such that the cover 135 covers the humidity detecting element 131. The other end of the cover 135 is fastened to the side wall of the air duct 111 through the first positioning fixing structure 15 . The detecting end 132 is housed in the other end of the cover 135. The other end of the cover 135 is provided with a plurality of through holes 1351 communicating with the inside of the cover 135.

Thus, the arrangement of the cover 135 can effectively reduce the influence of moisture and other substances (for example, ash layers) in the air passage 111 on the humidity detecting element 131, and then ensure the accuracy of the detection by the humidity detecting element 131. In addition, the cover 135 can realize the inflow and out of the airflow through the plurality of through holes 1351.

In some embodiments, the upper side of the cover 135 is formed with a downwardly inclined flow guiding surface 1352.

Thus, under the action of the flow guiding surface 1352, the water in the moisture can flow obliquely downward along the flow guiding surface 1352, so that the water in the moisture can be effectively reduced from entering the cover 135.

Referring to FIGS. 1 and 6, in some examples, one end of the cover 135 is fixed to the fixed plate 134 such that the cover 135 covers the humidity detecting element 131. The other end of the cover 135 is fixed to the side wall 1131 of the air outlet duct 113 via a fitting groove 154. The flow guiding surface 1352 is inclined downward from the side wall 1131 of the air outlet duct 113 toward the inside of the air duct 111. The angle a between the flow guiding surface 1352 and the horizontal direction n is greater than 0 degrees and less than or equal to 10 degrees. It can be understood that the angle a can be 1 degree, 2 degrees or 3 degrees. The angle a can be set according to the specific situation.

In certain embodiments, the fan assembly 10 includes a resilient seal ring 16. The sealing ring 16 is compressed between the first positioning fixing structure 15 and the second positioning fixing structure 133.

Thus, the arrangement of the sealing ring 16 can effectively prevent the moisture in the air passage 111 from leaking from the gap between the first positioning fixing structure 15 and the second positioning fixing structure 133, and can prevent the leaked moisture from entering the humidity detecting device 13. The other components (e.g., wire harness 136) have a negative impact on the humidity detecting device 13.

In the example shown in FIG. 1, the sealing ring 16 is compressively disposed between the mating end 153 and the fixed plate 134 to seal the fitting groove 154.

In certain embodiments, the humidity detecting device 13 includes a wire harness 136 and a joint 137. The wire harness 136 is electrically connected to the humidity detecting element 131 and the joint 137. The connector 137 is electrically connected to the controller 14. As such, the humidity detecting element 131 can effect transmission of electrical signals through the wire harness 136 and the connector 137.

In some embodiments, the humidity detecting element 131 is a humidity sensor.

Referring to Figure 8, a dishwasher 100 in accordance with an embodiment of the present invention includes a liner 20 and a fan assembly 10 of any of the embodiments. The liner 20 is provided with a washing chamber 21. The fan unit 10 is mounted on the side wall 22 of the inner liner 20. The side wall 22 of the inner liner 20 is provided with an air outlet 23 . The air outlet 23 communicates with the washing chamber 21 and the air passage 111.

In the dishwasher 100 of the embodiment of the present invention, the humidity detecting element 131 can detect the humidity in the air passage 111, so that the controller 14 can control the operation of the fan 12 according to the humidity in the air passage 111 to speed up the washing chamber 21 and the outside. The air circulation between them can effectively reduce the content of water vapor in the washing chamber 21, thereby preventing the generation of odor and the moisture return of the washing chamber 21 of the dishwasher 100.

It should be noted that when the fan 12 is in operation, the moisture in the washing chamber 21 can flow out from the air outlet 23, then enter the air duct 111, and can be directly discharged to the outside under the action of the fan 12.
