[0029] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0030] See also Figure 1 , is a drying device 100 for a dishwasher 200 provided in an embodiment of the present application. The drying device 100 can dry the dishes and the inside of the dishwasher 200 after washing to reduce moisture residue and prevent bacterial growth. Figure 2 As shown, the drying device 100 can include an air duct housing 10 , a fan 20 , a heating element 30 and an air door 40 .

[0031] Combine Figure 3Specifically, the air duct shell 10 can have an air intake port 1, a first air outlet 2 and a second air outlet 3. The air intake port 1 and the first air outlet 2 can both be connected to the inner tank 201 of the dishwasher 200. The gas in the inner tank 201 can enter the air duct shell 10 through the air intake port 1, and the gas in the air duct shell 10 can enter the inner tank 201 from the first air outlet 2, so that the air duct shell 10 and the inner tank 201 can form a circulating air path, so that the gas can circulate between the air duct shell 10 and the inner tank 201 and dry the inner tank 201. The second air outlet 3 can be connected to the outside world, so that the gas in the air duct shell 10 can also be discharged to the outside world from the second air outlet 3, that is, the gas in the inner tank 201 can be discharged to the outside world.

[0032] The damper 40 can be movably arranged inside the air duct shell 10, and a heating channel 5 can be provided between the damper 40 and the first air outlet 2, and a dehumidification channel 6 can be provided between the damper 40 and the second air outlet 3, so that the inner liner 201 and the heating channel 5 can form a circulating air path, and the dehumidification channel 6 can directly discharge the moisture in the inner liner 201 to the outside, and the damper 40 can be used to control the connection between the first air outlet 2 and the exhaust port 1, and the damper 40 can also be used to control the connection between the second air outlet 3 and the exhaust port 1. It can also be said that the damper 40 can open one of the heating channel 5 and the dehumidification channel 6, and the damper 40 can close the other of the heating channel 5 and the dehumidification channel 6.

[0033] The fan 20 can be disposed within the air duct housing 10 and adjacent to the air outlet 1. The fan 20 can draw the gas in the inner container 201 from the air outlet 1 into the heating channel 5 or the dehumidification channel 6. The heating element 30 can be disposed within the heating channel 5 and heat the gas within the heating channel 5.

[0034] At the beginning of the washing process of the dishwasher 200, there is a lot of water vapor in the inner tank 201. At this time, the dehumidification channel 6 can be opened and the heating channel 5 can be closed through the damper 40, and the fan 20 can be used to directly draw the water vapor in the inner tank 201 into the dehumidification channel 6 and discharge it to the outside from the second air outlet 3, so that the water vapor in the inner tank 201 can be directly discharged to the outside, so that the humidity in the inner tank 201 is quickly reduced, which can reduce the drying time and thus improve the drying efficiency. When most of the water vapor in the inner tank 201 is discharged, the heating channel 5 can be opened and the dehumidification channel 6 can be closed through the damper 40, and the heating element 30 can be turned on. The fan 20 can draw the gas in the inner tank 201 into the heating channel 5, and the gas is heated by the heating element 30 and returns to the inner tank 201 from the first air outlet 2. The heated gas can further dry the inner tank 201, so that the inner tank 201 can be kept dry.

[0035] Therefore, the water vapor in the inner liner 201 is first discharged from the second air outlet 3 through the dehumidification channel 6, and then the gas is heated by the heating element 30, and the hot gas circulates between the inner liner 201 and the heating channel 5, which can quickly reduce the humidity in the inner liner 201, reduce the drying time, and improve the drying efficiency.

[0036] See also Figure 2 and Figure 3 In some embodiments, an exhaust channel 4 can be provided between the exhaust port 1 and the damper 40, and the fan 20 is arranged in the exhaust channel 4, the exhaust channel 4 can be connected with the dehumidification channel 6, and the exhaust channel 4 can also be connected with the heating channel 5, so that the gas in the inner tank 201 can be sucked into the exhaust channel 4 by the fan 20, and the gas in the exhaust channel 4 can choose to flow into the heating channel 5, and the gas heated by the heating element 30 can return to the inner tank 201, and the inner tank 201 or the tableware in the inner tank 201 can be dried with hot air. The gas in the exhaust channel 4 can also choose to flow to the dehumidification channel 6, and thus be discharged to the outside through the second air outlet 3.

[0037] Optionally, the dehumidification channel 6 and the heating channel 5 can be connected to each other, or it can be said that the air duct shell 10 defines the exhaust channel 4, the dehumidification channel 6 and the heating channel 5 that are connected to each other, and the damper 40 can be movably arranged in the exhaust channel 4, and the connecting point between the exhaust channel 4 and the dehumidification channel 6 is adjacent to the damper 40, and the connecting point between the exhaust channel 4 and the heating channel 5 is also adjacent to the damper 40, so that the damper 40 can open one of the dehumidification channel 6 and the heating channel 5, and close the other of the dehumidification channel 6 and the heating channel 5.

[0038] When it is necessary to discharge moisture from the inner liner 201, the damper 40 opens the dehumidification channel 6 and closes the heating channel 5, so that the fan 20 draws moisture from the inner liner 201 from the air outlet 1 into the air outlet channel 4. The moisture can then be discharged to the outside through the second air outlet 3 via the dehumidification channel 6, thereby quickly reducing the humidity in the inner liner 201. When it is necessary to dry the tableware in the inner liner 201 or the inner liner 201 with hot air, the damper 40 opens the heating channel 5 and closes the dehumidification channel 6, so that the fan 20 draws air from the inner liner 201 from the air outlet 1 into the air outlet channel 4. The air can then flow through the heating channel 5, be heated by the heater 30, and then return to the inner liner 201 from the first air outlet 2, thereby quickly drying the inner liner 201 and the tableware therein through the circulating hot air.

[0039] See also Figure 3In some embodiments, a first connecting port 7 can be provided at the connection point between the exhaust channel 4 and the dehumidification channel 6, and a second connecting port 8 can be provided at the connection point between the exhaust channel 4 and the heating channel 5. The damper 40 can be rotatably installed between the first connecting port 7 and the second connecting port 8, and the damper 40 can open one of the first connecting port 7 and the second connecting port 8, and close the other of the first connecting port 7 and the second connecting port 8.

[0040] Specifically, when the damper 40 opens the first connecting port 7 and closes the second connecting port 8, the exhaust channel 4 is connected to the dehumidification channel 6 through the first connecting port 7, and the exhaust channel 4 is separated from the heating channel 5 by the damper 40. After the fan 20 draws the gas in the inner tank 201 from the exhaust port 1 into the exhaust channel 4, the gas can pass through the dehumidification channel 6 and be discharged to the outside from the second air outlet 3, thereby quickly reducing the humidity in the inner tank 201.

[0041] When the damper 40 opens the second connecting port 8 and closes the first connecting port 7, the exhaust channel 4 is connected to the heating channel 5 through the second connecting port 8, and the exhaust channel 4 is separated from the dehumidification channel 6 by the damper 40. After the fan 20 draws the gas in the inner tank 201 from the exhaust port 1 to the exhaust channel 4, the gas can pass through the heating channel 5, and after the gas is heated by the heating element 30, it can return to the inner tank 201 from the first air outlet 2, thereby forming circulating hot air to quickly dry the inner tank 201 and tableware.

[0042] Combine Figure 3 As shown, in some embodiments, the first communicating port 7 and the second communicating port 8 can be arranged adjacent to each other, and the plane where the first communicating port 7 is located intersects with the plane where the second communicating port 8 is located, so that when the damper 40 is rotatably installed between the first communicating port 7 and the second communicating port 8, the first communicating port 7 and the second communicating port 8 can be opened or closed by rotating the damper 40, which is very convenient to operate.

[0043] Optionally, the damper 40 can be connected to the driving unit in a transmission manner, so that the driving unit can drive the damper 40 to rotate between the first connecting port 7 and the second connecting port 8, so that the driving unit can drive the damper 40 to open or close the first connecting port 7 and the second connecting port 8, and the driving unit can be electrically connected to the micro switch, and the micro switch can control the driving unit to open or close.

[0044] Preferably, the plane where the first connecting port 7 is located is set at an angle to the plane where the second connecting port 8 is located, and this angle is an acute angle. When the damper 40 rotates within the angle range formed by the plane where the first connecting port 7 is located and the plane where the second connecting port 8 is located, only a small angle of rotation of the damper 40 is required to control the opening and closing states of the first connecting port 7 and the second connecting port 8, which can save installation space.

[0045] See also Figure 1 and Figure 2 In some embodiments, the exhaust port 1 can be connected to the top surface of the inner liner 201, and the first air outlet 2 can be connected to the side of the inner liner 201, the exhaust channel 4 can be partially located on the top of the inner liner 201, and the heating channel 5 can be located on the side wall of the inner liner 201, and the exhaust channel 4 can extend vertically along the side wall of the inner liner 201 to connect with the heating channel 5.

[0046] Optionally, the first air outlet 2 can be connected to the side of the inner liner 201 and close to the bottom, so that the fan 20 can draw the gas on the top of the inner liner 201 from the exhaust port 1 to the exhaust channel 4, and the gas flows from the exhaust channel 4 to the heating channel 5, and the heated gas can return to the bottom of the inner liner 201 from the first air outlet 2, and the hot gas can form an upward airflow in the inner liner 201, so that the hot gas can naturally rise and be drawn from the exhaust port 1 into the exhaust channel 4, thereby making it easier to form circulating hot air to dry the inner liner 201.

[0047] Optionally, the ventilation channel 4 is disposed at the top of the inner liner 201, so that the ventilation channel 4 can more effectively suck and discharge the hot air and moisture accumulated in the inner liner 201. More clearly, the ventilation channel 4 being located at the top of the inner liner 201 can help form an upward airflow in the inner liner 201, so that the hot air and moisture naturally rise and are more easily sucked by the fan 20 in the ventilation channel 4.

[0048] The heating channel 5 is arranged on the side wall of the inner pot 201, and the exhaust channel 4 can extend vertically along the side wall of the inner pot 201 to communicate with the heating channel 5, so that the first air outlet 2 of the heating channel 5 can be communicated with the side wall of the inner pot 201, so that the gas in the inner pot 201 can be discharged from the opening at the top, and after passing through the exhaust channel 4 and the heating channel 5, it can return to the inner pot 201 from the opening on the side wall of the inner pot 201, which can increase the disturbance of the airflow in the inner pot 201, and then promote the circulation of the airflow in the inner pot 201, so that the heated gas can be more evenly distributed in the inner pot 201, so that the inner pot 201 and the tableware in the inner pot 201 can be dried more evenly.

[0049] See also Figure 1 and Figure 2 In some embodiments, the heating channel 5 is located on the side wall of the inner tank 201 , and the heating channel 5 can be extended laterally along the side wall of the inner tank 201 , and the heating channel 5 can be set at an angle to the exhaust channel 4 .

[0050] Optionally, the heating channel 5 is extended laterally along the side wall of the inner tank 201, so that the heating channel 5 can have a certain length, thereby increasing the time for the gas to pass through the heating channel 5, so that the heating element 30 can fully heat the gas in the heating channel 5, and the extension direction of the heating channel 5 is set at an angle to the extension direction of the exhaust channel 4, so that the connection between the heating channel 5 and the exhaust channel 4 can form a curved arc surface, so that the flow direction of the gas in the exhaust channel 4 is different from the flow direction of the gas in the heating channel 5, which can appropriately reduce the flow rate of the gas in the heating channel 5, so that the heating element 30 can evenly heat the air around it, thereby improving the uniformity of heating.

[0051] See also Figure 3 In some embodiments, the heating element 30 can be arranged in the middle position of the heating channel 5, so that the heating element 30 can heat the heating channel 5 more evenly, so that the gas passing through the heating channel 5 is heated more evenly.

[0052] Optionally, the heating element 30 is set in the middle position of the heating channel 5, and the corners at both ends of the heating channel 5 can be avoided. Since the corners are curved, the internal space at the corners of the heating channel 5 is smaller than the internal space in the middle of the heating channel 5. Therefore, the heating element 30 is set in the middle position of the heating channel 5, and a larger heating element 30 can be set, so that the gas in the heating channel 5 can be better heated.

[0053] See also Figure 2 and Figure 3 In some embodiments, the fan 20 can be located on the top of the inner container 201 , and the heating element 30 can be located on the side wall of the inner container 201 .

[0054] Optionally, the fan 20 is set at the top of the inner liner 201, so that the fan 20 can be closer to the exhaust port 1 of the exhaust channel 4, so that the fan 20 can provide greater suction force to suck the gas in the inner liner 201, so that the gas in the inner liner 201 can be more easily sucked into the exhaust channel 4.

[0055] The heating element 30 is arranged on the side wall of the inner pot 201, so that the heating element 30 can directly heat the gas and tableware in the inner pot 201, thereby improving the drying efficiency. Moreover, since the heating element 30 is close to the inner pot 201, the heat generated by the heating element 30 can be more effectively absorbed by the gas and tableware in the inner pot 201, thereby reducing heat energy waste.

[0056] See also Figure 2In some embodiments, the dehumidification channel 6 can be arranged side by side with the exhaust channel 4 on the inner liner 201, and a portion of the dehumidification channel 6 can be located at the top of the inner liner 201 and connected to the outside world, and another portion of the dehumidification channel 6 can extend vertically along the side wall of the inner liner 201 to connect with the exhaust channel 4.

[0057] Optionally, the dehumidification channel 6 and the exhaust channel 4 are arranged side by side on the inner liner 201, which can make the air duct shell 10 more compact, and a part of the dehumidification channel 6 is arranged on the top of the inner liner 201, and the second air outlet 3 can also be arranged on the top of the inner liner 201, which can facilitate the discharge of water vapor in the inner liner 201.

[0058] It should also be noted that extending the other part of the dehumidification channel 6 vertically to the side wall of the inner liner 201 and connecting it with the exhaust channel 4 can make the connection between the dehumidification channel 6 and the exhaust channel 4, as well as the connection between the heating channel 5 and the exhaust channel 4 be on the side wall of the inner liner 201 and arranged adjacent to each other, which can facilitate the damper 40 to open one of the dehumidification channel 6 and the heating channel 5, and to close the other of the dehumidification channel 6 and the heating channel 5.

[0059] See also Figure 1 In some embodiments, the second air outlet 3 can be located at the top of the inner liner 201, and the second air outlet 3 can be set toward the top of the inner liner 201, so that the second air outlet 3 can discharge the moisture in the inner liner 201 upward, which can prevent the second air outlet 3 from blowing directly toward the front of the inner liner 201 during dehumidification, or in other words, it can prevent the second air outlet 3 from blowing moisture toward the person in front of the inner liner 201.

[0060] See also Figures 3 to 5 In some embodiments, the air duct shell 10 can include a first shell 101 and a second shell 102. The first shell 101 can be provided with an air exhaust port 1, the second shell 102 can be provided with a second air outlet 3, and the first shell 101 and the second shell 102 can be connected to define an air exhaust channel 4, a heating channel 5, and a dehumidification channel 6.

[0061] Optionally, the first shell 101 can be arranged on the outer wall surface of the inner liner 201, and the first shell 101 is partially located at the top of the inner liner 201. The first shell 101 can also extend to the side wall of the inner liner 201, and the first shell 101 extends a certain length along the circumference of the inner liner 201. The part of the first shell 101 located at the top of the inner liner 201 can be provided with an exhaust port 1.

[0062] The second shell 102 can be connected to the first shell 101, and the part of the second shell 102 located at the top of the inner liner 201 can be provided with a second air outlet 3. The second shell 102 and the first shell 101 can be snapped or screwed together, so that the exhaust channel 4, heating channel 5, and dehumidification channel 6 formed by the first shell 101 and the second shell 102 can discharge the moisture in the inner liner 201 to the outside through the air duct formed by the first shell 101 and the second shell 102, and can also form a circulating hot air to dry the inner liner 201.

[0063] Optionally, the second shell 102 can also define the first air outlet 2 together with the first shell 101 . Of course, the first shell 101 can also form the first air outlet 2 alone.

[0064] See also Figure 5 and Figure 6 As shown, in some embodiments, the air duct housing 10 may further include a cover shell 103 , and the cover shell 103 may be connected to the first shell 101 and the second shell 102 .

[0065] Specifically, the cover 103 and the first shell 101 or the second shell 102 can be an integral structure, that is, the cover 103 and the first shell 101 or the second shell 102 are formed as a whole, or the cover 103 and the first shell 101 and the second shell 102 are a split structure, that is, the cover 103 and the first shell 101 and the second shell 102 are snap-fitted together. The inner liner 201 can be provided with an opening, and the opening here refers to a second opening 2013 provided on the inner liner 201, the second opening 2013 is located in the lower half of the inner liner 201, and the cover 103 can be covered on the second opening 2013. It should be noted that the size of the second opening 2013 is smaller than that of the cover 103, or in other words, the cover 103 can completely cover the second opening 2013.

[0066] To be more clear, the cover shell 103 is formed with an air inlet cavity 1031, which can be connected to the second opening 2013, and the air inlet cavity 1031 can be connected to the heating channel 5 through the first air outlet 2, so that the heating channel 5 is connected to the inner liner 201 through the first air outlet 2 and the air inlet cavity 1031 in sequence, which can facilitate the gas in the heating channel 5 to enter the inner liner 201 through the air inlet cavity 1031.

[0067] Combine Figure 1 and Figure 5 In some embodiments, a portion of the duct shell 10 is located on the top of the inner liner 201, and another portion of the duct shell 10 is bent and extended to the side wall of the inner liner 201, so that the duct shell 10 can define an installation opening 104, and the duct shell 10 can be adapted and installed on the inner liner 201 through the installation opening 104.

[0068] Optionally, the air duct shell 10 can include a first air duct section and a second air duct section, and the second air duct section can be bent and extended toward one side relative to the first air duct section, so that the first air duct section and the second air duct section can be set at an angle, and the shape formed by the first air duct section and the second air duct section can be adapted to the inner liner 201. It can also be said that a mounting port 104 can be formed between the first air duct section and the second air duct section, and the mounting port 104 can be adapted to the inner liner 201, so that the air duct shell 10 can be adapted and installed on the inner liner 201 through the mounting port 104, which can reduce the difficulty of assembling the air duct shell 10 on the inner liner 201.

[0069] See also Figure 1 and Figure 2 The present invention provides a dishwasher 200. Dishwasher 200 may include an inner container 201 and a drying device 100. Inner container 201 is typically made of stainless steel or other corrosion-resistant, easy-to-clean materials. Inner container 201 may define a receiving cavity 2011 for loading dishes to be washed. Inner container 201 may also have a wall surface provided with a first opening 2012 and a second opening 2013, both of which communicate with receiving cavity 2011.

[0070] Optionally, the exhaust port 1 can be connected to the first opening 2012, so that the exhaust channel 4 can be connected to the inner liner 201 through the first opening 2012, and the first air outlet 2 can be connected to the second opening 2013, so that the heating channel 5 can be connected to the inner liner 201 through the second opening 2013, so that the exhaust channel 4, the heating channel 5, and the inner liner 201 can form circulating hot air, and the inner liner 201 can be dried by the circulating hot air.

[0071] Optionally, the first opening 2012 can be set on the top surface of the inner liner 201, and the second opening 2013 can be set on the side of the inner liner 201, so that the gas on the top of the inner liner 201 can be discharged outward from the first opening 2012 into the exhaust channel 4, and the gas is heated into hot air after passing through the heating channel 5. The hot air can return to the bottom of the inner liner 201 from the second opening 2013. Since the hot air can naturally form an upward airflow, the hot air can flow from the bottom of the inner liner 201 to the first opening 2012 at the top, and be sucked into the exhaust channel 4 by the fan 20, so that circulating hot air can be easily formed.
