[0002] Currently, the door panels of most dishwashers include an inner door panel and an outer door panel, and the door panels of the dishwasher are generally a drop-down door structure, that is, the bottom of the inner door panel and the dishwasher are connected in a rotating manner, and the outer door panel is assembled on the inner door panel. By pulling down the handle on the outer door panel, the inner door panel is driven to rotate downward relative to the inner tank, thereby opening the dishwasher.

[0003] However, when the dishwasher is performing high water level detection, the hot water in the inner tank will penetrate between the inner door panel and the outer door panel to detect the high water level through the water level sensor between the inner door panel and the outer door panel. Therefore, the inner door panel and the inner tank cannot be completely sealed. Therefore, during the washing process of the dishwasher, steam will also penetrate between the inner door panel and the outer door panel. Due to the narrow space between the inner door panel and the outer door panel, the humidity between the inner door panel and the outer door panel will be too high, and the steam will form condensation water on the electrical components between the inner door panel and the outer door panel, which may cause the electrical components to short-circuit and fail.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0031] See also Figure 1 and Figure 2 As shown, the utility model provides a dishwasher 100, which includes a main body 101 and an exhaust device 102, wherein the main body 101 includes a shell 1011, which is generally made of metal or plastic material and is used to protect internal components and provide an operation panel.

[0032] Specifically, the exhaust device 102 may include an inner tank, a door body 1 and a dehumidification component 2. The inner tank is arranged in the outer shell 1011. The inner tank is usually made of stainless steel, has corrosion resistance and high temperature resistance, and is used to accommodate and wash tableware. The door body 1 is rotatably installed on the outer shell 1011, so that the door body 1 can close or open the inner tank. Preferably, the door body 1 is rotatably installed on the outer shell 1011 with a pull-down structure. The user can open the dishwasher 100 by pulling the door body 1 downward. The pull-down door opening method can make the door body 1 more stable when opening and closing.

[0033] The dehumidification component 2 is arranged inside the door body 1. The dehumidification component 2 can discharge the water vapor that penetrates into the door body 1, so that the inside of the door body 1 can maintain a dry environment, so that the electrical components installed inside the door body 1 can be in a dry environment for a long time, and the formation of condensation water on the surface of the electrical components can be avoided, thereby preventing the electrical components from short-circuiting and failing.

[0034] Combination Figures 2 to 4 Specifically, the door body 1 may include an inner door 11 and an outer door 12. In some embodiments, the inner door 11 may be mounted on the outer shell 1011 of the dishwasher 100 via a hinge structure, and the hinge structure is preferably a door hinge, so that the inner door 11 may rotate relative to the outer shell 1011, so that the inner door 11 may open or close the inner container in the outer shell 1011. In other embodiments, the inner door 11 may also be rotatably connected to the outer shell 1011 via other hinged means. In this case, the outer door 12 may be directly mounted on the side of the inner door 11 facing away from the inner container, so that the outer door 12 and the inner door 11 are assembled into the door body 1, so that the inner door 11 and the outer door 12 may rotate synchronously, and an installation space 13 may be formed between the inner door 11 and the outer door 12.

[0035] In other embodiments, the outer door 12 may be hinged to the outer shell 1011 via a door hinge, and the outer door 12 may be assembled on the side of the inner door 11 facing away from the inner tank, so that the inner door 11 and the outer door 12 are assembled into a whole, and an installation space 13 may be formed between the inner door 11 and the outer door 12.

[0036] The dehumidification component 2 is arranged in the installation space 13, so that the dehumidification component 2 is located between the inner door 11 and the outer door 12, and is used to absorb the water vapor that penetrates into the door body 1 to the outside of the door body 1. It can also be said that the water vapor in the installation space 13 can be discharged through the dehumidification component 2, so that the installation space 13 can maintain a dry environment.

[0037] Combination Figure 2 as well as Figure 5 The dehumidification component 2 may have a dehumidification air duct 201. In this embodiment, a second air inlet 204 is provided at one end of the dehumidification air duct 201, and the dehumidification air duct 201 is connected with the installation space 13 through the second air inlet 204, so that the water vapor in the installation space 13 can enter the dehumidification air duct 201, and an air outlet 202 is provided at the other end of the dehumidification air duct 201, and the dehumidification air duct 201 is connected with the external air through the air outlet 202, so that the gas in the dehumidification air duct 201 can be discharged from the installation space 13.

[0038] Specifically, the dehumidification component 2 includes a fan 21, which is arranged in the dehumidification air duct 201. When the fan 21 is working, the fan 21 can suck the water vapor that has penetrated into the installation space 13 into the dehumidification air duct 201 from the second air inlet 204, and the fan 21 can also discharge the water vapor in the dehumidification air duct 201 from the air outlet 202 to the outside of the dishwasher 100, so that the installation space 13 can form convection with the external air of the dishwasher 100. Therefore, the water vapor between the inner door 11 and the outer door 12 can be discharged through the dehumidification component 2, and the humidity between the inner door 11 and the outer door 12 can be reduced, thereby avoiding the formation of condensation water on the electrical components between the inner door 11 and the outer door 12, thereby preventing the electrical components from short-circuiting and failing.

[0039] Combination Figure 5 As shown, in some embodiments, the dehumidification air duct 201 may further be provided with a first air inlet 203, the first air inlet 203 may be arranged adjacent to the second air inlet 204, and the first air inlet 203 may pass through the opening 111 on the inner door 11 (see Figure 2 ) is connected to the inner liner, so that the dehumidification air duct 201 can be connected to the inner liner.

[0040] The dehumidification component 2 may also include a damper 22, which is rotatably installed in the dehumidification air duct 201, and the damper 22 is located between the second air inlet 204 and the first air inlet 203. The second air inlet 204 can be opened or closed by rotating the damper 22, and the first air inlet 203 can also be opened or closed by rotating the damper 22.

[0041] When the water vapor in the installation space 13 needs to be discharged, the second air inlet 204 can be opened by rotating the damper 22, so that the installation space 13 and the dehumidification air duct 201 are connected, so that the water vapor in the installation space 13 can be discharged from the dehumidification air duct 201 outside the dishwasher 100, so that the installation space 13 remains dry.

[0042] When the water vapor discharge operation in the installation space 13 is completed, the second air inlet 204 can be closed by rotating the damper 22, so that the installation space 13 and the dehumidification air duct 201 are independent of each other, preventing the water vapor in the dehumidification air duct 201 from flowing back into the installation space 13 through the second air inlet 204.

[0043] Specifically, the damper 22, the second air inlet 204 and the first air inlet 203 have the following three switch states:

[0044] In the first switching state, when the damper 22 opens the first air inlet 203 and closes the second air inlet 204, the dehumidification air duct 201 is connected to the inner tank, and the dehumidification air duct 201 and the installation space 13 are independent of each other. At this time, the moisture and odor in the inner tank can be sucked into the dehumidification air duct 201 and discharged outside the dishwasher 100 by the fan 21, so that moisture and odor will not enter the installation space 13, so that the installation space 13 can be kept dry.

[0045] In the second switching state, when the damper 22 opens the second air inlet 204 and closes the first air inlet 203, the dehumidification air duct 201 is connected to the installation space 13, and the dehumidification air duct 201 and the inner tank are independent of each other. At this time, by closing the first air inlet 203, the hot steam in the inner tank can be prevented from entering the dehumidification air duct 201, and the fan 21 can discharge the water vapor in the installation space 13 and the dehumidification air duct 201 outside the dishwasher 100, so that the installation space 13 and the dehumidification air duct 201 remain dry.

[0046] The third switching state, when the damper 22 opens the second air inlet 204 and the first air inlet 203, the dehumidification air duct 201 is connected to the installation space 13, and the dehumidification air duct 201 is also connected to the inner tank. At this time, the fan 21 can suck the water vapor in the inner tank into the dehumidification air duct 201 through the first air inlet 203, and suck the gas in the installation space 13 into the dehumidification air duct 201 through the second air inlet 204. In this process, the gas in the installation space 13 and the gas in the inner tank can be mixed and discharged from the dehumidification air duct 201 to the outside of the dishwasher 100, so that the installation space 13 and the inner tank are kept dry.

[0047] In some other embodiments, when the dishwasher 100 is in the washing stage, the damper 22 opens the second air inlet 204 and closes the first air inlet 203. At this time, the dehumidification air duct 201 is connected to the installation space 13, and the dehumidification air duct 201 is independent of the inner tank.

[0048] Specifically, the washing stage is the core stage in the washing process of the dishwasher 100. The main purpose of this stage is to perform strong cleaning, and the tableware is repeatedly rinsed under high pressure by high-temperature and high-pressure water flow or hot steam. The temperature in this stage is relatively high, generally between 60 and 70 degrees Celsius, which can effectively dissolve and remove oil and other stubborn stains. By closing the first air inlet 203, the hot steam in the inner tank can be prevented from entering the dehumidification duct 201, and the fan 21 can discharge the water vapor in the installation space 13 and the dehumidification duct 201 out of the dishwasher 100, so that the installation space 13 and the dehumidification duct 201 remain dry, preparing for the next drying stage of the dishwasher 100.

[0049] When the dishwasher 100 is in the drying stage, the damper 22 has two switching modes:

[0050] The first one is that the damper 22 closes the second air inlet 204 and opens the first air inlet 203. At this time, the dehumidification duct 201 is connected to the inner tank, and the dehumidification duct 201 is independent of the installation space 13. The main purpose is to evaporate the water stains on the tableware and the inner tank through high temperature or dry air, so that the tableware and the inner tank become dry and clean. When the fan 21 is working, it can suck the water vapor in the inner tank into the dehumidification duct 201, and then discharge it out of the dishwasher 100, so that the inner tank and tableware remain dry.

[0051] The second type is that the damper 22 opens the second air inlet 204 and the first air inlet 203. At this time, the dehumidification air duct 201 is connected to the installation space 13, and the dehumidification air duct 201 is also connected to the inner tank. The fan 21 can draw the water vapor in the inner tank into the dehumidification air duct 201, and draw the gas in the installation space 13 into the dehumidification air duct 201, so that the two gases are mixed in the dehumidification air duct 201 and then discharged from the dishwasher 100, so that the installation space 13 and the inner tank remain dry.

[0052] Combination Figure 5 As shown, in some embodiments, the dehumidification assembly 2 may further include a drying element 24, and the drying element 24 may be disposed on the inner wall of the dehumidification air duct.

[0053] Specifically, the drying element 24 can be arranged adjacent to the air inlet of the fan 21, and the drying element 24 is located upstream of the fan 21, or in other words, the drying element 24 is located on the air inlet side of the fan 21. When the fan 21 draws the water vapor in the inner tank into the dehumidification air duct 201, along the flow direction of the gas, the drying element 24 is located upstream of the fan 21. The water vapor entering the dehumidification air duct 201 will first pass through the drying element 24. After the drying element 24 absorbs the moisture in the water vapor, the dry gas is discharged to the outside of the dishwasher 100 through the fan 21, which can avoid the gas with high humidity passing through the fan 21 and prevent the fan 21 from getting damp.

[0054] In some other embodiments, the drying element 24 may also be located downstream of the fan 21. Specifically, the drying element 24 is located on the air outlet side of the fan 21, and the drying element 24 is arranged adjacent to the air outlet of the fan 21. When the fan 21 draws the water vapor in the inner tank into the dehumidification air duct 201, along the flow direction of the gas, the drying element 24 is located downstream of the fan 21. After the water vapor entering the dehumidification air duct 201 passes through the fan 21, it is dried by the drying element 24 and then discharged from the dishwasher 100. Some drying elements 24 may generate dust. Setting the drying element 24 on the air outlet side of the fan 21 can prevent dust from entering the interior of the fan 21, thereby keeping the fan 21 clean and operating normally.

[0055] In some embodiments, the drying element 24 may include at least one of a MOF material, a zeolite, calcium dichloride, and lithium chloride.

[0056] Specifically, the full name of MOF material in English is Metal-Organic Frameworks, and its full name in Chinese is Metal-Organic Framework Material. MOF has a porous structure, which can make the drying element 24 have good adsorption and separation properties and can absorb moisture in water vapor very well.

[0057] Zeolite is a natural or synthetic aluminosilicate with a very large internal surface area and high porosity, which can make the drying element 24 have excellent adsorption and ion exchange properties. It can be used for drying and purifying gases and liquids and can effectively dry the gas in the dehumidification duct 201.

[0058] Calcium dichloride is a white or off-white solid, hygroscopic, and can absorb a large amount of moisture in the air. It is mainly used for drying and dehydrating gases. Calcium dichloride has good stability and is not easy to deteriorate, so that the drying element 24 can be stored and used for a long time.

[0059] Lithium chloride is a white or light yellow crystal with high thermal stability and hygroscopicity, and is mainly used for drying and dehydrating gases, so that the drying element 24 can be used in a higher temperature environment, which is more suitable for the use environment of the dishwasher 100.

[0060] Furthermore, the drying element 24 can release the absorbed water vapor under the condition of a temperature not higher than 72°C. Since the maximum temperature of the dishwasher 100 during operation is generally not higher than 72°C, when the dishwasher 100 is washed with hot water or high-temperature hot steam, the heat in the inner tank can be transferred to the drying element 24, so that the temperature of the drying element 24 increases and the absorbed water can be released for restoration. This can facilitate the drying element 24 to absorb the water vapor discharged from the inner tank when the dishwasher 100 is in the drying stage next time, so that the drying element 24 can be recycled and always maintain good water absorption.

[0061] See also Figure 5 As shown, in some embodiments, the drying element 24 is attached to the air duct wall of the dehumidification air duct 201 , which can facilitate the drying element 24 to absorb water vapor passing through the dehumidification air duct 201 and also facilitate the installation of the drying element 24 .

[0062] Specifically, the drying element 24 may include a plurality of drying units, and the plurality of drying units may be arranged in sequence and spaced apart on the air duct wall of the dehumidification air duct 201. By arranging the plurality of drying units at intervals, the moisture absorption area may be increased, thereby increasing the moisture absorption amount, and further reducing the humidity of the gas discharged from the dishwasher 100. In addition, by arranging the plurality of drying units at intervals, the airflow resistance in the dehumidification air duct 201 may be reduced, thereby allowing the gas to flow more smoothly in the dehumidification air duct 201.

[0063] To be more specific, the number and spacing of the drying units can be flexibly adjusted according to the length and humidity of the air duct. For example, in an area with high humidity, i.e., a section of the air duct near the opening 111 of the dehumidification air duct 201, the number of drying units on the section of the air duct can be increased or the spacing can be reduced to improve the drying effect; while in an area with low humidity, i.e., a section of the air duct near the air outlet 202 of the dehumidification air duct 201, the number of drying units can be reduced or the spacing can be increased to reduce the wind resistance in the dehumidification air duct 201.

[0064] The dehumidification component 2 may further include an air duct shell 23, which may be disposed in the installation space 13, and the air duct shell 23 may form a dehumidification air duct 201. In some embodiments, the air duct shell 23 includes an inner shell and an outer shell, the inner shell is mounted on the inner door 11, the outer shell is mounted on the outer door 12, and the inner shell and the outer shell may be assembled together so that the inner shell and the outer shell constitute the dehumidification air duct 201, the drying element 24 may be located between the inner shell and the outer shell, and the drying element 24 is attached to the inner shell.

[0065] In other embodiments, the air duct shell 23 can also be integrally formed to form the dehumidification air duct 201, and the drying component 24 is attached to the position where the air duct shell 23 contacts the inner door 11, so that the drying component 24 can indirectly contact the inner tank through the air duct shell 23 and the inner door 11 in sequence, so that the heat transfer distance between the drying component 24 and the inner tank is shortest, which can facilitate the inner tank to heat the drying component 24, so that the drying component 24 releases moisture for restoration.

[0066] Specifically, when the dishwasher 100 is in the main wash stage, the inner door 11 and the inner tank are in a sealed state, and the dishwasher 100 will rinse the dishes with high-temperature and high-pressure hot steam. At this time, the temperature of the inner tank is relatively high, and the heat of the inner tank can heat the drying component 24 through the inner door 11 and the air duct shell 23, so that the drying component 24 can release the previously absorbed moisture for restoration. At this time, the fan 21 can also be in a working state to discharge the moisture released by the drying component 24 out of the dishwasher 100, and the airflow formed by the fan 21 can dry the drying component 24 to a certain extent. The restored drying component 24 has better water absorption. After waiting for the dishwasher 100 to wash the dishes, in the drying stage of the dishwasher 100, the inner door 11 is connected to the inner tank, and the fan 21 can quickly draw the water vapor in the inner tank into the dehumidification air duct 201, and the drying component 24 can better absorb the moisture in the water vapor, so that the humidity of the gas discharged from the dishwasher 100 is always maintained at a low level.

[0067] In some embodiments, the air duct shell 23 can also form a dehumidification air duct 201 together with the inner door 11, and the drying component 24 is attached to the inner door 11, so that the inner tank can directly heat the drying component 24 through the inner door 11, the heating effect is better, the drying component 24 can release more moisture, and the reduction effect of the drying component 24 is better.

[0068] See also Figure 2 As shown, specifically, an opening 111 can be provided at the upper half of the inner door 11, and the dehumidification air duct 201 formed by the air duct shell 23 can be provided with a first air inlet 203, and the dehumidification air duct 201 can extend to the upper half of the door body 1, so that the first air inlet 203 is located in the upper half of the door body 1, so that the first air inlet 203 can be connected with the opening 111, so that when the door body 1 closes the inner tank, the dehumidification air duct 201 can be connected with the upper half of the inner tank through the inner door 11, and when the dishwasher 100 is in the drying stage, the high-temperature gas in the inner tank moves from the bottom to the upper half, which can facilitate the gas in the inner tank to be discharged from the dishwasher 100 from the dehumidification air duct 201.

[0069] Combination Figure 8The dehumidification component 2 may further include a sealing ring 25, which may be disposed between the air duct shell 23 and the inner door 11, and the sealing ring 25 may be disposed around the opening 111, or it may be said that the sealing ring 25 is disposed between the opening 111 and the first air inlet 203 to seal the gap between the air duct shell 23 and the inner door 11, so that the gas will not leak when flowing through the opening 111 and the first air inlet 203.

[0070] In some embodiments, when the dishwasher is in the drying stage, when the damper 22 opens the first air inlet 203 and closes the second air inlet 204, the dehumidification air duct 201 is connected to the inner tank, and the dehumidification air duct 201 is independent of the installation space 13. The fan 21 can draw the water vapor in the inner tank into the dehumidification air duct 201, and after the moisture is absorbed by the drying element 24, it is discharged from the dishwasher 100, so that the humidity of the gas discharged from the dishwasher 100 is reduced, which can prevent the exhausted gas from condensing on the cabinet or the floor to form water stains.

[0071] Similarly, when the damper 22 opens the second air inlet 204 and the first air inlet 203, the dehumidification duct 201 is connected to the installation space 13, and the dehumidification duct 201 is also connected to the inner tank. The fan 21 can draw the water vapor in the inner tank into the dehumidification duct 201, and draw the gas in the installation space 13 into the dehumidification duct 201, so that the two gases are mixed in the dehumidification duct 201, and after absorbing moisture through the drying element 24, they are discharged from the dishwasher 100.

[0072] In some embodiments, when the dishwasher is in the washing stage, the damper 22 opens the second air inlet 204 and closes the first air inlet 203. The heat generated in the washing stage is transferred to the drying element 24 through the inner door 11, so that the drying element 24 can release the absorbed water for restoration after the temperature rises, so that the drying element 24 can restore its water absorption capacity.

[0073] At the same time, the fan 21 can suck the gas in the installation space 13 into the dehumidification duct 201, and discharge the water vapor in the dehumidification duct 201 out of the dishwasher 100 to take away the water vapor on the drying element 24, so that the installation space 13 and the dehumidification duct 201 remain dry, and the drying element 24 has a good moisture absorption capacity after being restored, so as to prepare for the next drying stage of the dishwasher 100.

[0074] See also Figures 5 to 9 As shown, in some embodiments, the air duct housing 23 may include an air intake section 231 and an air exhaust section 232, and the air intake section 231 and the air exhaust section 232 are connected to each other.

[0075] Specifically, the air intake section 231 is arranged in the upper half of the installation space 13, and the air intake section 231 is connected to the air intake side of the fan 21, and the air intake section 231 can define a dehumidification air duct 201 for air intake, so that when the fan 21 is working, the fan 21 can draw the gas in the upper half of the installation space 13 to the air intake section 231.

[0076] Combination Figure 5 and Figure 6 The air intake section 231 may include a first air intake shell 2311 and a second air intake shell 2312, and the first air intake shell 2311 and the second air intake shell 2312 are arranged between the inner door 11 and the outer door 12. In this embodiment, the first air intake shell 2311 is installed on the inner door 11, and the second air intake shell 2312 is installed on the outer door 12. In other embodiments, the first air intake shell 2311 may be installed on the outer door 12, and the second air intake shell 2312 may be installed on the inner door 11, and the first air intake shell 2311 and the second air intake shell 2312 may be assembled together to construct a dehumidification air duct 201 for air intake.

[0077] In some embodiments, the fan 21 and other electrical components, the second air inlet 204 and the first air inlet 203 are all arranged on the first air inlet shell 2311, so that the wiring harnesses on the fan 21 and other electrical components can be concentrated on the same side, which can be conveniently summarized and organized, so that the interior of the exhaust device 102 can be kept tidy, and the fan 21 can be arranged more reasonably, so that the air inlet side of the fan 21 is connected to the second air inlet 204 and the first air inlet 203, so that the fan 21 can simultaneously suck the gas in the inner tank and the installation space 13.

[0078] In other embodiments, the second air inlet 204 is arranged on the first air inlet shell 2311, and the first air inlet 203 is arranged on the second air inlet shell 2312, or the second air inlet 204 is arranged on the second air inlet shell 2312, and the first air inlet 203 is arranged on the first air inlet shell 2311. Of course, it is also possible that the first air inlet shell 2311 is provided with a portion of the second air inlet 204 and a portion of the first air inlet 203, and the second air inlet shell 2312 is provided with another portion of the second air inlet 204 and another portion of the first air inlet 203. When the first air inlet shell 2311 and the second air inlet shell 2312 are assembled together, the first air inlet shell 2311 and the second air inlet shell 2312 form the second air inlet 204 and the first air inlet 203.

[0079] Combination Figure 5As shown, in some embodiments, the second air inlet 204 and the first air inlet 203 are arranged adjacent to each other, and the plane where the second air inlet 204 is located intersects with the plane where the first air inlet 203 is located, so that when the damper 22 is rotatably installed between the second air inlet 204 and the first air inlet 203, the second air inlet 204 and the first air inlet 203 can be opened or closed by rotating the damper 22, which is very convenient to operate.

[0080] Preferably, the plane where the second air inlet 204 is located is set at an angle with the plane where the first air inlet 203 is located, and this angle is an acute angle. When the damper 22 rotates within the angle range formed by the plane where the second air inlet 204 is located and the plane where the first air inlet 203 is located, only a small angle rotation of the damper 22 is required to control the opening and closing states of the second air inlet 204 and the first air inlet 203, which can save installation space.

[0081] See also Figures 6 to 8 As shown, in some embodiments, the exhaust section 232 can be arranged on the air outlet side of the fan 21, or it can be said that the exhaust section 232 is located in the lower half of the installation space 13, and the exhaust section 232 can define a channel for the dehumidification duct 201 to exhaust air, and the exhaust section 232 has an air outlet 202 at the end away from the fan 21, so that the exhaust section 232 can be connected to the external air.

[0082] Among them, see Figure 8 and Fig. 9 As shown, the channel defined by the exhaust section 232 gradually widens in the direction away from the fan 21, and the thickness of the exhaust section 232 gradually decreases in the direction approaching the air outlet 202, so that the flow area of ​​the dehumidification air duct 201 gradually flattens. It can also be said that the cross-sectional area of ​​the dehumidification air duct 201 itself gradually becomes flat, so that the air outlet 202 has a flat structure. In this way, the exhaust range of the air outlet 202 in the left and right directions of the door body 1 can be increased, and the water vapor in the installation space 13 can be discharged in a more dispersed manner.

[0083] Specifically, designing the air outlet 202 as a flat structure can disrupt or change the flow direction of the gas, help eliminate or reduce noise of a specific frequency, thereby making the noise of the dehumidification duct 201 lower, and the flat air outlet 202 design can more effectively guide or accelerate the discharge of the gas, improve the discharge efficiency, and evenly disperse the gas in all directions, reducing the probability of the discharged water vapor flowing back into the installation space 13.

[0084] See also Figure 2 and Figure 8 As shown, in some embodiments, the air duct shell 23 may further include a cover shell 233 , and the cover shell 233 is connected to the first air inlet shell 2311 .

[0085] Specifically, the cover 233 and the first air inlet shell 2311 can be an integrated structure, that is, the cover 233 and the first air inlet shell 2311 are formed as a whole, or the cover 233 and the first air inlet shell 2311 are split structures, that is, the cover 233 and the first air inlet shell 2311 are snap-fitted together. The inner door 11 can be provided with an opening 111, the opening 111 is located in the upper half of the inner door 11, and the cover 233 can be covered on the opening 111. It should be noted that the size of the opening 111 is smaller than the size of the cover 233, which can also be said that the cover 233 can completely cover the opening 111.

[0086] To be more clear, the cover shell 233 is formed with an air inlet chamber 2331, and the air inlet chamber 2331 can be connected to the opening 111, and the first air inlet port 203 is arranged on the side wall of the cover shell 233, and the air inlet chamber 2331 can be connected to the dehumidification air duct 201 through the first air inlet port 203. When the inner door 11 closes the inner tank, the air inlet chamber 2331 can be connected to the inner tank through the opening 111, so that the dehumidification air duct 201 is connected to the inner tank through the first air inlet port 203 and the air inlet chamber 2331 in sequence, which can facilitate the gas in the inner tank to enter the dehumidification air duct 201 through the air inlet chamber 2331, and facilitate the discharge of water vapor in the inner tank, so that the inner tank and tableware remain dry, and by setting the cover shell 233, water in the inner tank can be prevented from entering the dehumidification air duct 201, and even if water enters the air inlet chamber 2331, it can flow back to the inner tank.

[0087] See also Figure 4 As shown, in some embodiments, a convection port 14 may be further provided at the bottom of the door body 1. The shape of the convection port 14 may be circular or square, and the convection port 14 may be connected to the installation space 13, so that the water vapor in the dehumidification air duct 201 can be discharged through the convection port 14, and the installation space 13 is connected to the external air of the dishwasher 100 through the convection port 14, so that the external air can also enter the installation space 13 through the convection port 14.

[0088] In this embodiment, a notch may be provided at the bottom of the inner door 11, and a notch may also be provided at the bottom of the outer door 12. The opening ends of the two notches are arranged opposite to each other, so that when the outer door 12 and the inner door 11 are assembled together, the two notches can form a convection port 14. In other embodiments, the convection port 14 may be formed on the inner door 11 or the outer door 12 alone, or the convection port 14 may be formed on the inner door 11 and the outer door 12 respectively.

[0089] The dehumidification air duct 201 can extend to the bottom of the door body 1, and the air outlet 202 of the dehumidification air duct 201 can be connected to the external air through the convection port 14, so that the gas in the dehumidification air duct 201 can be discharged outward from the bottom of the door body 1. Compared with opening the convection port 14 on the side or top of the exhaust device 102, this embodiment can hide the convection port 14, and the user cannot see the convection port 14, which can improve the visual integrity and aesthetics of the exhaust device 102, and can also facilitate the production of an integrated door body 1.

[0090] At the same time, exhausting the gas from the bottom of the door body 1 can prevent the gas from blowing toward the human body when being exhausted, providing a more comfortable user experience.

[0091] See also Figure 3 , Figure 4 and Fig. 9 As shown, in some embodiments, after the dehumidification air duct 201 passes through the convection port 14, the dehumidification air duct 201 can be bent and extended toward one side of the door body 1, especially the dehumidification air duct 201 is bent and extended to fit with the bottom surface of the door body 1, so that the air outlet 202 at the end of the dehumidification air duct 201 can be set toward one side of the door body 1, preferably, the dehumidification air duct 201 is bent and extended toward the side of the outer door 12 facing away from the inner door 11, so that the air outlet 202 extends to the side of the outer door 12 facing away from the inner door 11.

[0092] When the door body 1 closes the inner tank, the convection port 14 is set toward the floor, and the air outlet 202 is set at an angle to the convection port 14, especially the air outlet 202 is perpendicular to the convection port 14, so that the air outlet 202 is not facing the ground, and because the air outlet 202 extends to the side of the outer door 12 facing away from the inner door 11, it can avoid the air outlet 202 facing the floor or cabinet or blowing directly during dehumidification, thereby further avoiding condensation on the cabinet or floor to form water stains, and because the air outlet 202 extends to the outside of the door body 1 through the convection port 14, the condensed water can gather at the bottom of the door body 1 and then flow to the ground, instead of flowing into the gap between the door body 1 and the skirting board.
