[0065] With the continuous improvement of living standards, users have higher demands for the performance of household dishwashers, including drying performance. Currently, there are many types of drying methods applied to commercially available dishwashers, mainly including residual heat method, internal circulation ventilation method, and external circulation ventilation method.

[0066] Residual heat drying is to increase the temperature of the water in the inner tank by increasing the washing temperature, and to use the residual heat of the inner tank to perform natural drying, which requires high energy consumption and has the disadvantage of slow drying speed. The internal circulation ventilation method is to extract the wet steam in the inner tank through a fan to a medium, which can remove the water in the steam, and then blow the dry air after removing the water into the inner tank to reduce the humidity in the inner tank and achieve the purpose of drying the dishes. The current methods of removing water in the steam are mainly condensation and adsorption, the efficiency of the condensation method is low, and it is very difficult to achieve the purpose of fast drying, and the adsorption method needs to add adsorption materials, which causes the problem of odor in the inner tank, and the equipment for these two types of moisture removal methods is relatively complicated and expensive. The external circulation method is to directly discharge the steam in the inner tank to the outside, the equipment is simple and efficient, but there is a problem of heat waste and the risk of forming condensed water outside the dishwasher.

[0067] There are various existing drying methods, but it is known that these drying methods have a drawback in that condensed water is easily generated when improving the drying efficiency.

[0068] In view of the above, the present application aims to provide an adjustment device applied to an exhaust system of a dishwasher, which can be used to wash tableware, cooking utensils, cutlery, etc. With reference to Figures 1 to 9, a specific embodiment in which an adjustment device 500 provided in the present application is applied to an exhaust system 30 of a dishwasher 1 is shown in the drawings.

[0069] The present application provides an exhaust system 30 adapted for use in a dishwasher 1 .

[0070] With reference to Figures 1 to 3, the present application provides a dishwasher 1, which includes a housing 10, an inner tank 20 installed in the housing 10, and an exhaust system 30, wherein the inner tank 20 is installed in the housing 10 and the exhaust system 30 is attached to the housing 10.

[0071] In addition, the inner tank 20 is generally installed inside the housing 10. When the inner tank 20 is in the cleaning stage, i.e. after the cooking utensils waiting to be cleaned in the inner tank 20 are cleaned, high-temperature and high-humidity steam (i.e., the first gas 901, steam 901 in the following embodiment) is generated, and in order to ensure the continued use of the inner tank 20 after the cleaning is completed, the high-temperature and high-humidity steam needs to be dried. Based on this, in this embodiment, the inner tank 20 has at least an exhaust port 21, and the exhaust system 30 communicates with the exhaust port 21 of the inner tank 20. When the inner tank 20 is in the exhaust stage, the high-temperature and high-humidity steam is exhausted from the exhaust port 21 of the inner tank 20 and enters the exhaust system 30, and after the action of the exhaust system 30, rapid drying is realized and no condensed water is generated.

[0072] The exhaust system 30 can be installed at any suitable position of the housing 10. For example, when specifically applied, it can be installed inside the housing 10 or outside the housing 10. Among them, when the exhaust system 30 is installed outside the housing 10, any operation such as attaching and detaching the exhaust system 30 does not interfere with the normal operation of the internal functional members of the dishwasher 1, which can contribute to improving usability. The exhaust system 30 may be installed on the top, bottom, or any side of the housing 10. When the dishwasher 1 is actually applied, it is generally fitted into a predetermined mounting groove of a wall or cabinet in a room, and only the front side of the dishwasher 1 is exposed. In one embodiment, the exhaust system 30 can be further installed on the front side of the dishwasher 1, which can facilitate daily maintenance of the exhaust system 30 and contribute to the exhaust of the airflow.

[0073] When the exhaust system 30 is installed at the front side of the housing 10, in one specific embodiment, the housing 10 may include a box case with one side open and a door body movably installed to cover the opening of the box case, and the inner tank 20 is installed in the box case. Furthermore, the door body may also have an outer door body and an inner door body 110 stacked along the inward and outward direction, and when the exhaust system 30 is installed outside the inner door body 110 and shielded by the outer door body, the inner door body 110 can achieve mutual independence in installation between the inner tank 20, and the outer door body can protect the exhaust system 30, thereby improving the aesthetics of the entire equipment. Of course, in other solutions, the inner tank 20 may be installed, for example, on the door body, and the exhaust system 30 may be separately installed on the inside and outside of the door body.

[0074] With reference to FIG. 5, the exhaust system 30 provided in the present application includes an outer casing 400 and an adjustment device 500, in which the outer casing 400 is formed with an exhaust passage 410, a first intake port 420 and a second intake port 430, in which the first intake port 420 and the second intake port 430 are respectively connected to the exhaust passage 410, the first intake port 420 is connected to the inner tank 20 of the dishwasher 1 for taking in the first gas 901 discharged from the inner tank 20, and the second intake port 430 is for taking in a second gas 902 having a lower humidity than the first gas 901.

[0075] The adjustment device 500 includes an adjustment mechanism 500 and a control member, and the adjustment mechanism 500 is configured to control the ratio of the first gas 901 and the second gas 902 entering the exhaust passage 410 by adjusting, under the control of the control member, the flow rate of the first gas 901 entering the exhaust passage 410 through the first intake port 420 and the flow rate of the second gas 902 entering the exhaust passage 410 through the second intake port 430, respectively.

[0076] That is, the humidity of the second gas 902 is lower than the humidity of the first gas 901 .

[0077] In the technical solution provided in this application, the control member can realize the intelligent operation of the regulating mechanism according to a predetermined rule or actual need, and the regulating mechanism can respectively adjust the flow rate of the first gas 901 entering the exhaust passage 410 from the first inlet 420 and the flow rate of the second gas 902 entering the exhaust passage 410 from the second inlet 430 to adjust the ratio of the first gas 901 and the second gas 902 in the exhaust passage 410, so that when a large amount of the first gas 901 is discharged from the inner tank 20, the flow rate of the first gas 901 entering the exhaust passage 410 can be effectively reduced, and the first gas 901 can take in sufficient second gas 902 to realize the rapid drying of the first gas 901. In addition, when a small amount of the first gas 901 is discharged from the inner tank 20, the flow rate of the first gas 901 into the exhaust passage 410 can be effectively increased, and the drying efficiency of the first gas 901 can be improved. In addition, the first intake port 420 is directly connected to the exhaust passage 410, so that the first gas 901 discharged from the inner tank 20 can be directly dried, and the formation of a cooling medium on the path through which the first gas 901 enters the exhaust passage and the generation of condensed water can be avoided. The technical solution provided in this application not only improves the drying efficiency of the first gas 901 discharged from the inner tank 20, but also reduces or eliminates the generation of condensed water, and optimizes the drying effect.

[0078] The first intake port 420 of the outer casing 400 is disposed adjacent to the second intake port 430 so as to promote rapid mixing of the first gas 901 and the second gas 902. As described above, the first gas 901 generally refers to high-temperature and high-humidity steam exhausted through the exhaust port 21 of the inner tank 20, and the second gas 902 may be any gas drier than the first gas 901, specifically, outside air, or a dry gas specially taken in from another part of the dishwasher 1 or an external facility. Since the second gas 902 is drier than the first gas 901, when the first gas 901 and the second gas 902 are mixed, the mixed gas 903 neutralizes the humidity values ​​of the first gas 901 and the second gas 902, thereby realizing rapid drying.

[0079] The flow areas of the first air inlet 420 and the second air inlet 430 may be set to be substantially the same, or may be set to be different according to practical requirements.

[0080] In general, the outer casing 400 is provided with an exhaust port 440 communicating with the exhaust passage 410 so as to exhaust a mixed gas 903 obtained by mixing a first gas 901 and a second gas 902. Specifically, by providing the first intake port 420 and the second intake port 430 adjacent to each other at the same end of the exhaust passage 410 and providing the exhaust port 440 at the other end of the exhaust passage 410, the length of the flow path of the mixed gas 903 can be appropriately increased, and the first gas 901 can be sufficiently dried by the second gas 902.

[0081] The exhaust passage 410 is not limited in the extending direction relative to the housing 10, and may extend horizontally, vertically, or in other directions. When the exhaust passage 410 extends vertically, an exhaust port 440 can be selectively installed at the lower end of the exhaust passage 410, and the exhaust speed of the mixed gas 903 can be increased to some extent.

[0082] In one specific embodiment, the exhaust passage 410 is installed to extend downward to form a bent segment 402a and then bent horizontally, and the exhaust port 440 is installed at the end of the bent segment 402a to guide the mixed gas 903 to be exhausted horizontally, where the horizontal direction can be specifically expressed as the front-to-rear direction of the dishwasher 1.

[0083] The outer casing 400 may be integrally molded or may be configured by combining at least two casing structures, and when the outer casing 400 includes at least two casing structures, the exhaust passage 410 may be formed in any of the at least two casing structures. For example, in one embodiment, the outer casing 400 has a first casing 401 and a second casing 402 installed in this order from top to bottom, the exhaust passage 410 extends from the first casing 401 to the second casing 402, and the first casing 401 and the second casing 402 are installed detachably.

[0084] The specific method of detachable installation is not limited, and for example, as shown in Figures 2 and 4, an end of the first housing and an end of the second housing are internally and externally fitted together, and at the internally and externally fitted together point, a connecting member is provided on the first housing 401, and a butt member that connects to the connecting member is provided on the second housing 402.

[0085] The first housing 401 and the second housing 402 can be installed so that at least some of the parts are internally and externally fitted together, and one of the connecting member and the butting member is a snap 403, and the other is a snap hole 404. Based on this, the snap 403 is installed on one side of the fitting portion between the first housing 401 and the second housing 402, and the snap hole 404 is installed on the other side, and a detachable connection between the first housing 401 and the second housing 402 is realized by mutual snapping between the snap 403 and the snap hole 404. Furthermore, a locking rib 405 may be provided in a ring shape at the fitting portion between the first housing 401 and the second housing 402, and the locking rib 405 is selectively provided to have elasticity, and generates interference when the first housing 401 and the second housing 402 are fitted together, facilitating a reliable connection between the first housing 401 and the second housing 402.

[0086] In addition, the first housing 401 and / or the second housing 402 specifically include a bottom shell 401a and a cover shell 401b, one side of the bottom shell 401a is fixedly attached to the housing 10, the other side of the bottom shell 401a has an opening, and the cover shell 401b is provided to cover the opening of the bottom shell 401a and surrounds the bottom shell 401a to form at least a part of a passage segment of the exhaust passage 410 together with the bottom shell 401a. Among them, the bottom shell 401a and the cover shell 401b may be detachably connected by screwing, adhesive, snapping, suction, or the like.

[0087] The adjusting device 500 may include, but is not limited to, an adjusting mechanism and a control member, in which the control member may be, for example, an electrical control member such as a controller, a control circuit, etc., or an operating member for converting an external force into a driving force of the driving member 520, such as an operating handle, an operating hand wheel, a knob, etc. For ease of understanding, the following embodiment will be described as an example in which the control member is an electrical control member including a controller to realize intelligent automation of the exhaust system 30.

[0088] The adjustment mechanism acts on at least one of the first intake port 420 and the second intake port 430, and realizes control of the flow rates of the first gas 901 and the second gas 902 by changing the flow area of ​​the first intake port 420 and / or the second intake port 430. This makes it possible to adjust the ratio of the first gas 901 and the second gas 902 in the exhaust passage 410.

[0089] At least two of the adjustment mechanisms may be installed, and the two adjustment mechanisms are installed at the first intake port 420 and the second intake port 430, respectively, and independently adjust the gas flow rates of the first intake port 420 and the second intake port 430.

[0090] Of course, the adjusting mechanism may be provided in one, and the gas flow rate of the first intake port 420 and the gas flow rate of the second intake port 430 may be adjusted simultaneously by the one adjusting mechanism.

[0091] In one embodiment, the adjustment mechanism includes an adjustment material 510 movably attached to the outer casing 400, and a driving member 520 for driving the adjustment material 510 to move, the adjustment material 510 being attached between the first air intake port 420 and the second air intake port 430, and movably installed between the first air intake port 420 and the second air intake port 430, and the adjustment material 510 moves toward the first air intake port 420 to completely cover the first air intake port 420, and toward the second air intake port 430 to completely cover the second air intake port 430 under the driving of the driving member 520.

[0092] It should be noted that while the conditioning material 510 is moving toward the first inlet 420, the orthogonal projection area of ​​the conditioning material 510 on the first inlet 420 gradually increases, i.e., the shielding area of ​​the conditioning material 510 with respect to the first inlet 420 gradually increases, and the flow rate of the first gas 901 at the first inlet 420 gradually decreases until the flow rate of the first gas 901 becomes zero when the first inlet 420 is completely covered by the conditioning material 510. Conversely, while the conditioning material 510 is moving toward the second inlet 430, the orthogonal projection area of ​​the conditioning material 510 on the second inlet 430 gradually increases, i.e., the shielding area of ​​the conditioning material 510 with respect to the second inlet 430 gradually increases, and the flow rate of the second gas 902 at the second inlet 430 gradually decreases until the flow rate of the second gas 902 becomes zero when the second inlet 430 is completely covered by the conditioning material 510.

[0093] In addition, when the outer casing 400 is defined as having a connecting wall 450 located between the first air intake 420 and the second air intake 430, the orthogonal projection area of ​​the adjusting material 510 on the connecting wall 450 is selectively installed to be equal to or less than the area of ​​the connecting wall 450 and equal to or greater than the maximum flow area of ​​the first air intake 420 and the second air intake 430, so that only the first air intake 420 or the second air intake 430 is blocked during the stroke of the adjusting material 510, and neither the first air intake 420 nor the second air intake 430 is blocked when the adjusting material 510 moves between the first air intake 420 and the second air intake 430.

[0094] Of course, the orthogonal projection area of ​​the adjustment material 510 on the connecting wall 450 is selectively set to be larger than the area of ​​the connecting wall 450 and not smaller than the maximum flow area of ​​the first intake port 420 and the second intake port 430, so that during the movement stroke of the adjustment material 510, the first intake port 420 and / or the second intake port 430 are at least partially blocked, and the flow area of ​​one of the first intake port 420 and the second intake port 430 gradually increases and the flow area of ​​the other gradually decreases, thereby contributing to promoting the ratio adjustment of the first gas 901 and the second gas 902.

[0095] By installing the above-mentioned adjusting member 510 and driving member 520, the adjustment mechanism can be limited to adjust the flow rate of the first gas 901 entering the exhaust passage 410 through the first intake port 420 and the flow rate of the second gas 902 entering the exhaust passage 410 through the second intake port 430 stepwise or steplessly according to actual needs.

[0096] To achieve the above functions, the specific schemes of the adjusting mechanism are various.

[0097] In one embodiment, the adjustment member 510 is translatably mounted on the connecting wall 450, i.e., moves generally relative to the plane in which the connecting wall 450 is located. The driving member 520 drives the adjustment member 510 to translate, such that the adjustment member 510 translates toward the first air inlet 420 until it completely covers the first air inlet 420, and translates toward the second air inlet 430 until it completely covers the second air inlet 430.

[0098] The translatable installation may be, for example, a linear translation such that the adjustment material 510 is translated along the direction of a line connecting the first intake port 420 and the second intake port 430 so as to shorten the length of the translation path of the adjustment material 510. Of course, the translatable installation may be translated along a curve so as to change the shielding direction of the adjustment material 510 with respect to the first intake port 420 and / or the second intake port 430, thereby contributing to finely dividing the amount of shielding of the adjustment material 510 with respect to the first intake port 420 and / or the second intake port 430 and improving the accuracy of adjusting the ratio between the first gas 901 and the second gas 902.

[0099] In one embodiment, the adjustment member 510 has an attachment end and a free end arranged opposite to each other, of which the attachment end is rotatably attached to the connecting wall 450, and the driving member 520 drives the attachment end to rotate so that the free end of the adjustment member 510 rotates toward the first air inlet 420 until the adjustment member 510 completely covers the first air inlet 420, and rotates toward the second air inlet 430 so that the adjustment member 510 completely covers the second air inlet 430. The adjustment member 510 is arranged in a substantially plate-like shape, or has at least a plate surface arranged toward the first air inlet 420 and the second air inlet 430.

[0100] Specifically, the mounting end of the adjustment member 510 can be installed to be rotatable along a rotation axis extending in a direction approximately perpendicular to the connecting wall 450 so that the plate surface of the adjustment member 510 slides approximately along the surface on which the connecting wall 450 is located. Based on this, one free end can be installed to individually shield the first air intake 420 or the second air intake 430 in one rotation process, or two free ends can be installed, and the two free ends are located on opposite sides of the mounting end and are approximately blade-shaped.

[0101] 2 and 3, the mounting end of the adjusting material 510 can be installed to be rotatable along a rotation axis extending in a direction substantially parallel to the connecting wall 450 so that the plate surface of the adjusting material 510 rotates relative to the surface on which the connecting wall 450 is located. By installing in this manner, the adjusting material 510 surrounds the air passage cavity shell of the first gas 901 and / or the second gas 902 together with the inner wall of the exhaust passage 410 on the opposite side during the rotation process, and the air passage cavity shell is installed to gradually expand along the direction of the airflow, thereby sufficiently diffusing the first gas 901 and / or the second gas 902 while the first gas 901 and / or the second gas 902 are flowing, and contributing to rapid mixing of the first gas 901 and the second gas 902.

[0102] In one embodiment, the adjustment member 510 includes a fixed plate and a movable plate, and the fixed plate is fixedly installed to cover the first inlet 420 and / or the second inlet 430. For example, in the case where the fixed plate is fixedly installed to cover the first inlet 420, the fixed plate is provided with a plurality of first vent holes penetrating along its thickness direction, and the movable plate is provided with a plurality of second vent holes penetrating along its thickness direction. The movable plate is movably installed relative to the fixed plate, and during the movable stroke of the movable plate, the second vent holes are movably installed on the orthogonal projection area on the fixed plate and move to at least partially overlap or completely shift from the first vent holes, forming distributed vent holes of different shapes and sizes to distribute the first gas 901 and pass through in different amounts.

[0103] Next, in the case where the adjusting member 510 has a mounting end and a free end that are installed opposite to each other, of which the mounting end is rotatably attached to the connecting wall 450 as in the above embodiment, referring to Figs. 6 to 8, the driving member 520 includes a driving motor 521 and two rotating parts 522, of which the driving motor 521 is attached to the outer casing 400, specifically, selectively fixedly attached within the exhaust passage 410. The driving motor 521 is electrically connected to the control member and is operated under the control of the control member. The two rotating parts 522 are rotatably attached to the exhaust passage 410 and are arranged side by side against the inner wall of the exhaust passage 410, one of the two rotating parts 522 is connected to the driving motor 521, and the other is connected to the mounting end, among which, the two rotating parts 522 have opposing surfaces, and the opposing surfaces of the two rotating parts 522 are both provided with gear teeth 523, and the gear teeth 523 of the two rotating parts 522 mesh with each other. The rotating part 522 is installed in a substantially plate-like shape, and the gear teeth 523 are installed on the side of the plate. By installing in this manner, the two rotating parts 522 rotate the mounting end by the transmission of the meshing gear teeth 523 under the driving of the driving motor 521.

[0104] For ease of understanding, the rotating part 522 connected to the driving motor 521 is defined as a driven rotating part 522a, and the rotating part 522 connected to the mounting end of the adjusting member 510 is defined as a driven rotating part 522b. Specifically, in one embodiment, at least one of the driving rotating part 522a and the driven rotating part 522b may be installed so as to be formed on the corresponding driving motor 521 and / or the adjusting member 510. Taking the driven rotating part 522b as an example, the mounting end of the adjusting member 510 on the opposite side to the free end is installed in an arcuate shape, and gear teeth 523 are installed on this arcuate part. The gear teeth 523 can be extended to at least a part of the arcuate surface, and the part installed like the arcuate surface constitutes the driven rotating part 522b.

[0105] In another embodiment, at least one of the driving rotating part 522a and the driven rotating part 522b can be an individual member, and the corresponding driving motor 521 and / or the adjustment member 510 can be installed separately and can be installed as a gear structure when specifically applied. The respective rotation axes of the driving rotating part 522a and the driven rotating part 522b are installed in parallel with a gap therebetween, thereby achieving better meshing transmission between the driving rotating part 522a and the driven rotating part 522b.

[0106] In addition, the driving member 520 may be installed in other manners according to actual applications. Taking the pivotal mounting of the adjustment member 510 as an example, in one embodiment, the driving member 520 includes only a driving motor 521, and the driving motor 521 may be directly connected to the mounting end, or may be connected to the mounting end via a structure such as a coupling to pivotally drive the mounting end. In one embodiment, the driving motor 521 may include only a wax motor. In one embodiment, the driving member 520 may include a driving machine and a transmission assembly such as a link mechanism, a lever mechanism, an electromagnetic transmission mechanism, etc. Not described here.

[0107] In addition, in one embodiment, the exhaust system 30 further includes a connection structure installed on the adjustment material 510 and / or the outer casing 400, in which the connection structure has a first plate surface for covering the first air intake port 420, and when the adjustment material 510 moves to a position where it covers the first air intake port 420, the connection structure is used to connect to the first plate surface and the outer casing 400, thereby preventing the adjustment material 510 from hitting the outer casing 400 and bouncing back, thereby affecting the covering effect of the first plate surface on the first air intake port 420. And / or, the adjustment material 510 has a second plate surface for covering the second air intake port 430, and when the adjustment material 510 moves to a position where it covers the second air intake port 430, the connection structure is used to connect the second plate surface and the outer casing 400, thereby avoiding the adjustment material 510 hitting the outer casing 400 and bouncing off to affect the covering effect of the second plate surface facing the second air intake port 430.

[0108] In addition, there may be two connection structures, and when the two connection structures are installed between the first plate surface and the corresponding inner wall of the exhaust passage 410, and between the second plate surface and the corresponding inner wall of the exhaust passage 410, respectively, the two connection structures may be installed identically or differently.

[0109] There are many specific technical proposals for the connection structure. Take the connection structure installed between a first plate surface and the corresponding inner wall of the exhaust passage 410 as an example, the connection structure may include a connection portion installed on the first plate surface and a butt portion installed on the corresponding inner wall of the exhaust passage 410.

[0110] In one embodiment, the connecting portion may be an adsorbent material, and the butting portion may be an adhesive fitting material, and the connection between the first plate surface and the corresponding inner wall of the exhaust passage 410 is realized by the adhesive action when the adsorbent material and the adhesive fitting material approach each other, wherein the adsorbent material may be a suction cup, a magnetic structure, etc.

[0111] In one embodiment, the connecting portion may be an adhesive material, and the butting portion may be an adhesive fitting material, and the connection between the first plate surface and the corresponding inner wall of the exhaust passage 410 is realized by the adhesive action when the adhesive material and the adhesive fitting material approach each other, wherein the adhesive material may be a rubber strip or the like that is applicable under the current environment.

[0112] In one embodiment, the connecting portion may be a buckle, and the butting portion may be a buckle fitting, and the connection between the first plate surface and the corresponding inner wall of the exhaust passage 410 is realized by the buckle action when the buckle and the buckle fitting approach each other.

[0113] Of course, when the driving member 520 includes a driving rotating part 522a and a driven rotating part 522b as described above, the gear teeth 523 meshing with each other between the driving rotating part 522a and the driven rotating part 522b realize self-locking of the moving state of the driving rotating part 522a and the driven rotating part 522b when both are not rotating, thereby realizing self-locking of the moving state of the adjusting material 510 and achieving the purpose of avoiding the bouncing of the adjusting material 510 described above, and therefore the driving rotating part 522a and the driven rotating part 522b together constitute the connecting structure.

[0114] 6 and 8, in one embodiment, the adjusting material 510 is installed in a substantially plate-like shape to achieve a reduction in material weight, and the side of the adjusting material 510 facing the first air intake 420 and / or the side of the adjusting material 510 facing the second air intake 430 is the abutting side 513, that is, the side on which the above-mentioned first plate surface and / or second plate surface is located constitutes the abutting side 513. The adjusting material 510 has an elastic sealing layer 513a installed at least on the abutting side 513. For example, when the elastic sealing layer 513a is installed on the first plate surface, the elastic sealing layer 513a can seal the gap between the first plate surface and the peripheral side of the first air intake port 420 when the first plate surface covers the first air intake port 420, thereby preventing leakage of the first gas 901. Meanwhile, when the first plate surface covers the first air intake port 420, the elastic sealing layer 513a can mitigate the mutual impact between the first plate surface and the peripheral side of the first air intake port 420, thereby obtaining an impact absorption effect, which contributes to eliminating impact sounds and improves the service life of the adjusting material 510 and the outer casing 400.

[0115] The elastic sealing layer 513a may be made of an elastic material such as rubber or silicone, and may be molded integrally with the adjusting material 510. Specifically, at least a first plate surface of the adjusting material 510 is made of an elastic material. Alternatively, the elastic sealing layer 513a is provided separately from the adjusting material 510, and the two are detachably connected. The elastic sealing layer 513a may extend over the entire plate surface of the first plate surface, or may be provided corresponding to the joint between the first plate surface and the outer casing 400.

[0116] Furthermore, in one embodiment, the adjustment material 510 is provided with an engagement protrusion 513b in the middle of the abutment side 513, the engagement protrusion 513b having a shape and size that fits the corresponding first intake port 420 or the second intake port 430. The engagement protrusion 513b is used to engage and connect the first intake port 420 when the adjustment material 510 moves to a position where it covers the first intake port 420, and / or the engagement protrusion 513b is used to engage the second intake port 430 when the adjustment material 510 moves to a position where it covers the second intake port 430.

[0117] Similarly, taking the engaging protrusion 513b installed on the first plate surface as an example, the engaging protrusion 513b can enhance the covering effect of the first plate surface for the first air intake 420 by engaging with the first air intake 420, which corresponds to forming the above-mentioned connection structure and contributes to a reliable connection between the adjustment material 510 and the outer casing 400. The engaging protrusion 513b is installed so that its outer surface fits the outer surface shape of the outer casing 400 at that position when it engages with the first air intake 420, so that it is possible to avoid the formation of an unnecessary recess structure on the outer surface of the outer casing 400, which can contribute to improving the overall aesthetics.

[0118] As in the above, the engaging protrusion 513b may be formed integrally with the contact side 513, or may be formed separately from the contact side 513. When the elastic seal layer 513a and the engaging protrusion 513b are provided on the contact side 513, the elastic seal layer 513a can spread over the entire plate surface of the contact side 513 and be sandwiched between the engaging protrusion 513b and the contact side 513, or the elastic seal layer 513a is provided in a ring shape along the circumferential side of the engaging protrusion 513b.

[0119] Furthermore, at least the peripheral side wall of the engaging protrusion 513b may be made elastic, and when the engaging protrusion 513b engages with the first air intake port 420 or the second air intake port 430, it can elastically abut against the inner edge of the corresponding first air intake port 420 or second air intake port 430, thereby further enhancing the sealing effect and connection strength.

[0120] 6-7, in one embodiment, the exhaust system 30 further includes a position sensor 600, which is provided in the outer casing 400, specifically, may be installed in the exhaust passage 410, and the position sensor 600 may be electrically connected to the control member and controlled by the control member to operate. When the adjustment member 510 moves to cover the first intake port 420, the position sensor 600 is used to send a sensing signal to the control member, thereby making it possible to better know whether the first gas 901 discharged from the inner tank 20 has entered the exhaust passage 410, and to associate the operating states between the exhaust system 30 and the inner tank 20.

[0121] There are many specific technical solutions for the position sensor 600. In one embodiment, the position sensor 600 may be a non-contact sensor, an optical sensor, an image recognition sensor, etc., but is not limited thereto. Based on this, the position sensor 600 is installed on the moving path of the adjustment material 510, and when the adjustment material 510 moves to pass the position sensor 600, it is captured by the position sensor 600 to trigger a sensing signal.

[0122] In one embodiment, the position sensor 600 may be, but is not limited to, a contact sensor, a pressure sensor 800, a stroke switch, etc. Based on this, the position sensor 600 is installed on the contact side 513 or the inner wall of the exhaust passage 410 contacting the contact side 513, so that when the adjustment member 510 moves to cover the first intake port 420, the position sensor 600 hits and triggers a detection signal.

[0123] Taking as an example a case where the position sensor 600 is a contact sensor, specifically, in one embodiment, the adjustment material 510 comprises a plate-shaped main body 511 and a mounting plate portion 512 which is provided at an end of the plate-shaped main body 511, rotatably attached to the exhaust passage 410, and constitutes the mounting end, the position sensor 600 has an electrical contact 610, and on the side of the mounting plate portion 512 facing the electrical contact 610, a contact protrusion 514 is provided which abuts against the electrical contact 610 when the adjustment material 510 moves to cover the first air intake port 420.

[0124] As can be seen, the installation of the mounting plate portion 512 can enhance the mounting stability between the adjustment material 510 and the inner wall of the exhaust passage 410, and contribute to increasing the moment of the contact protrusion 514, so that when the adjustment material 510 just covers the first air intake port 420, the contact protrusion 514 just abuts against the electrical contact 610, and exerts a butting force on the electrical contact 610, so that the position sensor 600 can capture the current state and form a sensing signal.

[0125] Further, in one embodiment, the contact protrusion 514 has a front side close to the electrical contact 610 and a rear side far from the electrical contact 610, and the front wall of the contact protrusion 514 may be inclined or arcuate to form a guide surface, and when the contact protrusion 514 moves toward the electrical contact 610, interference is formed between the contact protrusion 514 and the electrical contact 610, and the amount of interference gradually increases, i.e., the thrust force applied by the contact protrusion 514 to the electrical contact 610 gradually increases.

[0126] Furthermore, by providing the mounting plate portion 512 in an openwork shape, the mass of the adjustment member 510 on the mounting plate portion 512 can be reduced.

[0127] 2 and 3, in one embodiment, the first intake port 420 and the second intake port 430 are installed at an incline so as to gradually move away from the exhaust passage 410 in a direction in which they approach each other. That is, the plane on which the first intake port 420 is located and the plane on which the second intake port 430 is located are installed at an included angle to each other, and the included angle between the two on the side facing the exhaust passage 410 is less than 180°. By installing in this manner, the flow direction of the first gas 901 entering the exhaust passage 410 through the first intake port 420 and the flow direction of the second gas 902 entering the exhaust passage 410 through the second intake port 430 are installed so as to gradually approach each other. Therefore, the first gas 901 and the second gas 902 merge and mix more quickly, and the drying effect of the first gas 901 is improved.

[0128] In view of the above, in order to increase the versatility of the exhaust system 30 for dishwashers 1 with different specifications, in one embodiment, an air guide passage 460 is provided in the outer casing 400. A passage opening at one end of the air guide passage 460 is connected to the exhaust port 21 of the inner tank 20, and a passage opening at the other end of the air guide passage 460 is the first intake port 420, and a first gas 901 from the inner tank 20 flows in from the exhaust port 21, passes through the air guide passage 460, and is then discharged from the first intake port 420 to the exhaust passage 410. The air guide passage 460 extends in a curved manner so as to guide the first gas 901 in the exhaust passage 410 toward the second intake port 430.

[0129] In addition, the air guide passage 460 can change the direction of the first gas 901 exhausted through the exhaust port 21 of the inner tank 20, and then guide the first gas 901 from the first intake port 420 into the exhaust passage 410. Therefore, the positional design of the first intake port 420 and the second intake port 430 in the exhaust system 30 is not limited by the installation position of the exhaust port 21 of the inner tank 20, which can contribute to improving the versatility of the exhaust system 30.

[0130] In addition, the outer casing 400 can also install an air guide structure 470 in the exhaust passage 410, and the specific form of the air guide structure 470 can be various, for example, an air guide plate installed adjacent to the first air intake 420 and / or the second air intake 430, or an arc-shaped segment formed on the inner wall of the exhaust passage 410, which guides the first gas 901 and the second gas 902 to mix rapidly, and prevents the first gas 901 from drying late and condensing on the inner wall of the exhaust passage 410 to generate condensed water.

[0131] 2 and 5, in one embodiment, the exhaust system 30 further includes a first fan 700, which is installed in the exhaust passage 410 and used to drive the gas in the exhaust passage 410 to the exhaust outlet 440, and accelerates the rapid flow of the first gas 901, the second gas 902 and the mixed gas 903. The first fan 700 is electrically connected to the control member and can be operated under the control of the control member.

[0132] According to the above embodiment, the control member can control the operation of the regulating mechanism, specifically, when the dishwasher 1 is in the washing stage, the control member controls the regulating mechanism to regulate the flow rate of the first gas 901 to the exhaust passage 410 to zero, i.e., drives the regulating member 510 to cover the first intake port 420, to prevent high-temperature and high-humidity steam in the inner tank 20 from leaking to the outside and reducing the cleaning effect. When the dishwasher 1 is in the exhaust stage and the amount of steam is large, the control member controls the regulating mechanism to regulate the first gas 901 and the second gas 902 to enter the exhaust passage 410 respectively, and adjust the ratio between the first gas 901 and the second gas 902 to be within an appropriate range, so that the first gas 901 has a sufficient exhaust amount, and the second gas 902 quickly dries the first gas 901, to avoid the generation of condensed water. When the dishwasher 1 is in the exhaust stage and the amount of steam drops to a predetermined value, the control member controls the regulating mechanism to allow the first gas 901 to enter the exhaust passage 410 at a maximum flow rate, thereby achieving rapid exhaust of the first gas 901.

[0133] The above control procedure can be realized by installing a relevant program in the control member. For example, a time period is set according to the exhaust discipline of the dishwasher 1, and the first gas 901 and the second gas 902 are adjusted to an appropriate ratio for a predetermined time after the first air inlet 420 is opened, and after this predetermined time, the first air inlet 420 is adjusted to be fully open so that the flow rate of the first gas 901 is maximized.

[0134] 2 and 5, in one embodiment, the exhaust system 30 further includes a sensor 800 including a temperature detection module and a humidity detection module, the sensor 800 is provided in the exhaust passage 410 and used to respectively detect the temperature and humidity values ​​in the exhaust passage 410. Wherein, the control member is electrically connected to the sensor 800, and controls the regulating mechanism to operate correspondingly according to a predetermined rule according to the received temperature value and humidity value.

[0135] The temperature detection module and the humidity detection module are installed separately and together form one detection module to form the sensor 800. Alternatively, the temperature detection module and the humidity detection module are integrally configured to form the sensor 800.

[0136] Further, in one embodiment, as described above, the exhaust system 30 further includes a first fan 700 installed in the exhaust passage 410 and electrically connected to the control member, and the sensor 800 may be installed upstream or downstream of the first fan 700, i.e., it may be installed farther from the exhaust port 440 or closer to the exhaust port 440 according to actual needs.

[0137] And / or, the sensor 800 is installed adjacent to the first fan 700. For example, in an actual application, referring to FIG. 2, the sensor 800 may be installed downstream of the first fan 700 and adjacent to the first fan 700.

[0138] In one embodiment, the dishwasher 1 further includes a second fan, which is provided in the inner tank 20 and drives the gas flow in the inner tank 20 so that the first gas 901 can enter the exhaust passage 410 more quickly. The second fan is electrically connected to the control member and can be operated under the control of the control member.

[0139] And / or, in one embodiment, the dishwasher 1 further includes a heater, which is provided in the inner tank 20 and can heat the gas in the inner tank 20 to form a desired hot air. The heater is electrically connected to the control member and can be operated under the control of the control member.

[0140] In some embodiments, the first inlet 420 is a steam inlet 420 and the second inlet 430 is an air inlet 430, and the first gas 901 may be steam and the second gas 902 may be air.

[0141] The outer casing 400 is formed with an exhaust passage 410, and a steam inlet 420 and an air inlet 430 which are each connected to the exhaust passage 410. The steam inlet 420 is connected to the inner tank 20 of the dishwasher 1 and is used to take in steam 901 discharged from the inner tank 20, and the air inlet 430 is used to take in outside air 902 which has a lower humidity than the steam 901.

[0142] The regulating device 500 includes an adjusting material 510 movably installed between the air inlet 430 and the steam inlet 420, a driving member 520, and a control member, the driving member 520 drives the adjusting material 510 to move between the air inlet 430 and the steam inlet 420, and adjusts the flow rate of steam 901 entering the exhaust passage 410 through the steam inlet 420 and / or the flow rate of air 902 entering the exhaust passage 410 through the air inlet 430, the control member is electrically connected to the driving member 520, and controls the moving position of the adjusting material 510 between the air inlet 430 and the steam inlet 420 to control the ratio of the steam 901 and the air 902 entering the exhaust passage 410.

[0143] In the technical solution provided in this application, the control member can control and operate the driving member 520 according to a predetermined rule or actual need, so as to realize the intelligent operation of the regulator 510, and the regulator 510 can adjust the flow rate of the steam 901 entering the exhaust passage 410 from the steam inlet 420 and / or the flow rate of the external air 902 entering the exhaust passage 410 from the air inlet 430, so as to adjust the ratio of the steam 901 and the air 902 in the exhaust passage 410, so as to effectively reduce the flow rate of the steam 901 entering the exhaust passage 410 when a large amount of the steam 901 is discharged from the inner tank 20, so as to take in sufficient air 902 into the steam 901 to realize the rapid drying of the steam 901. When a small amount of the steam 901 is discharged from the inner tank 20, the flow rate of the steam 901 entering the exhaust passage 410 can be effectively increased, so as to improve the drying efficiency of the steam 901. The installation of the regulating device 500 allows the steam 901 discharged from the inner tank 20 to be directly dried, and prevents the formation of a cooling medium in the path of the steam 901 entering the exhaust passage, which would otherwise cause condensation. The technical solution provided in this application not only improves the drying efficiency of the steam 901 discharged from the inner tank 20, but also reduces or eliminates the generation of condensation, and optimizes the drying effect.

[0144] When exhaust system 30 is applied to dishwasher 1, outer casing 400 may be integrally formed with housing 10 and installed, or may be installed separately from housing 10. When outer casing 400 is installed separately from housing 10, the manner of attachment between them is not limited, and possible methods include screw engagement fixation by screw engagement between a screw and a screw hole, snap engagement fixation by snap engagement between a snap and a buckle, and suction fixation by suction fitting between an adsorbent and a fitting member.

[0145] The outer casing 400 may be directly and fixedly attached to the housing 10, or may be fixedly attached to the housing 10 by an additionally installed mounting structure. Specifically, as shown in Fig. 2 and Fig. 9, in one embodiment, the exhaust system 30 further includes a fixing seat 406, which is substantially plate-shaped and installed between the housing 10 and the outer casing 400, the fixing seat 406 is screw-engaged and fixed to the housing 10 by a screw, a convex boss 406a is provided on the side of the fixing seat 406 facing the outer casing 400, and a concave groove (not shown) is provided on the outer casing 400 at a position corresponding to the boss 406a, and the concave-convex fit between the boss 406a and the concave groove can realize accurate positioning of the outer casing 400 relative to the housing 10.

[0146] Next, the fixing seat 406 may have an engaging member (not shown) protruding from one of the outer circumferential side of the boss 406a and the inner circumferential side of the recessed groove, and an engaging groove 407 recessed from the other, and the outer casing 400 may be detachably mounted on the housing 10 by the engagement between the engaging member and the engaging groove 407, making the removal operation easy. For example, the engaging groove 407 may be provided on the outer circumferential side of the boss 406a, and a plurality of the engaging grooves 407 may be provided on the outer circumferential side of the boss 406a, and the plurality of engaging grooves 407 may be arranged at intervals in the circumferential direction of the boss 406a.

[0147] The fixing seat 406 may further include a number of reinforcing ribs 408 at the screw engagement points, which contribute to increasing the connection strength at that position, thereby contributing to a stable attachment of the exhaust system 30 to the housing 10.

[0148] The steam inlet 420 of the outer casing 400 is disposed adjacent to the air inlet 430 so as to promote rapid mixing of the steam 901 and the air 902. As described above, the steam 901 generally refers to high-temperature and high-humidity steam exhausted through the exhaust port 21 of the inner tank 20, and the air 902 may be any gas drier than the steam 901, such as indoor air 902 or a dry gas specially taken in from another part of the dishwasher 1 or an external facility. Since the air 902 is drier than the steam 901, when the steam 901 and the air 902 are mixed, the mixed gas 903 neutralizes the humidity values ​​of the steam 901 and the air 902, thereby realizing rapid drying.

[0149] The flow areas of the steam inlet 420 and the air inlet 430 may be set to be substantially the same, or may be set to be different according to practical requirements.

[0150] The outer casing 400 is generally provided with an exhaust port 440 communicating with an exhaust passage 410 so as to exhaust a mixed gas 903, which is a mixture of steam 901 and air 902. Specifically, by installing the steam inlet 420 and the air inlet 430 close to each other at the same end of the exhaust passage 410 and installing the exhaust port 440 at the other end of the exhaust passage 410, the length of the flow path of the mixed gas 903 can be appropriately extended, and sufficient drying of the steam 901 by the air 902 can be achieved.

[0151] The adjusting device 500 acts on at least one of the steam inlet 420 and the air inlet 430, and correspondingly changes the flow area of ​​the steam inlet 420 and / or the air inlet 430 to realize control of the flow rates of the steam 901 and the air 902, thereby making it possible to adjust the ratio of the steam 901 and the air 902 in the exhaust passage 410.

[0152] Specifically, the adjusting material 510 moves between the steam inlet 420 and the air inlet 430, and correspondingly changes the flow area of ​​the steam inlet 420 and / or the air inlet 430, thereby realizing control of the flow rates of the steam 901 and air 902, and enabling the ratio of the steam 901 and the air 902 in the exhaust passage 410 to be adjusted.

[0153] At least two of the adjustment elements 510 may be installed, and the two adjustment elements 510 are installed at the steam inlet 420 and the air inlet 430, respectively, and adjust the gas flow rates of the steam inlet 420 and the air inlet 430 independently.

[0154] Of course, the adjusting member 510 may be provided in a single unit, and the single adjusting member 510 can adjust the gas flow rate of the steam inlet 420 and the gas flow rate of the air inlet 430 at the same time.

[0155] By installing the above-mentioned adjusting member 510 and driving member 520, the adjusting device 500 can be limited to adjust the flow rate of the steam 901 entering the exhaust passage 410 through the steam inlet 420 and / or the flow rate of the air 902 entering the exhaust passage 410 through the air inlet 430 in a stepped or stepless manner according to actual needs.

[0156] Under the drive of the driving member 520, the conditioning material 510 can move towards the steam inlet 420 to cover the steam inlet 420 and move towards the air inlet 430 to cover the air inlet 430.

[0157] In order to achieve the above functions, the adjusting device 500 may have various specific configurations.

[0158] In one embodiment, the conditioning material 510 is translatably disposed between the steam inlet 420 and the air inlet 430, and under the driving of the driving member 520, the conditioning material 510 can translate toward the steam inlet 420 until it covers the steam inlet 420, and can translate toward the air inlet 430 until it covers the air inlet 430.

[0159] The translatable installation may be, for example, a linear translation such that the adjustment material 510 is translated along the direction of a line connecting the steam inlet 420 and the air inlet 430 so as to shorten the length of the translation path of the adjustment material 510. Of course, the translatable installation may be translated along a curve so as to change the shielding direction of the adjustment material 510 with respect to the steam inlet 420 and / or the air inlet 430, thereby contributing to finely dividing the amount of shielding of the adjustment material 510 with respect to the steam inlet 420 and / or the air inlet 430 and improving the accuracy of adjusting the ratio between the steam 901 and the air 902.

[0160] In one embodiment, the outer casing 400 has a connecting wall 450 located between the steam inlet 420 and the air inlet 430, the adjustment member 510 is attached to the connecting wall 450, and the connecting wall 450 is rotatably installed, specifically, the adjustment member 510 has an attachment end and a free end arranged opposite to each other, the attachment end is movably connected to the connecting wall 450, and under the driving of the driving member 520, the adjustment member 510 can rotate the free end of the adjustment member 510 toward the steam inlet 420 until it covers the steam inlet 420, and the adjustment member 510 can rotate toward the air inlet 430 to cover the air inlet 430. The adjustment member 510 is installed in a substantially plate-like shape, or at least has a plate surface arranged toward the steam inlet 420 and the air inlet 430.

[0161] 2 to 4, the mounting end of the adjusting material 510 can be installed to be rotatable along a rotation axis extending in a direction approximately parallel to the connecting wall 450 so that the plate surface of the adjusting material 510 rotates relative to the surface on which the connecting wall 450 is located. By installing in this manner, the adjusting material 510 surrounds the wind-passing cavity shell of the steam 901 and / or air 902 together with the inner wall of the exhaust passage 410 on the opposite side during the rotation process, and the wind-passing cavity shell is installed to gradually expand along the direction of the airflow, thereby sufficiently diffusing the steam 901 and / or air 902 while the steam 901 and / or air 902 are flowing, which can contribute to rapid mixing of the steam 901 and the air 902.

[0162] Next, in one embodiment, the driving member 520 includes a driver and a transmission mechanism provided in the outer casing 400, and the transmission mechanism connects the driver and the adjustment member 510. The driver may be installed to have a rotating output shaft or an expanding output shaft according to an operation method of the adjustment member 510, and the transmission mechanism connects the driver and the adjustment member 510 to transmit the power of the driver to the adjustment member 510.

[0163] Taking the pivotal mounting of the adjustment member 510 as an example, in one embodiment, the driving member 520 includes only a driving motor 521, and the driving motor 521 may be directly connected to the mounting end, or may be connected to the mounting end via a structure such as a coupling to pivotally drive the mounting end, and in one embodiment, the driving motor 521 may include only a wax motor. The transmission mechanism may be a link mechanism, a lever mechanism, an electromagnetic transmission mechanism, etc., and will not be described here.

[0164] In the case where the adjustment member 510 has an attachment end and the attachment end is rotatably attached to the connection wall 450 as in the above embodiment, referring to Figs. 6 to 8, the drive member 520 includes a drive motor 521 and two rotating parts 522, of which the drive motor 521 is attached to the outer casing 400, specifically, selectively fixedly attached in the exhaust passage 410, and the drive motor 521 is electrically connected to the control member and is controlled by the control member to operate. The two rotating parts 522 are rotatably attached in parallel to the exhaust passage 410, one of the two rotating parts 522 is connected to the drive motor 521 and the other is connected to the attachment end, and the two rotating parts 522 are provided with gear teeth 523 that mesh with each other at least at a position where they face each other. It can be seen that the rotating part 522 is provided in a substantially plate-like shape, and the gear teeth 523 are provided on the side of the plate. By installing in this manner, when driven by the driving motor 521, the two rotating parts 522 rotate the mounting end by the transmission of the gear teeth 523 which mesh with each other.

[0165] For ease of understanding, the rotating part 522 connected to the driving motor 521 is defined as a driven rotating part 522a, and the rotating part 522 connected to the mounting end of the adjusting member 510 is defined as a driven rotating part 522b. Specifically, in one embodiment, at least one of the driving rotating part 522a and the driven rotating part 522b may be installed so as to be formed on the corresponding driving motor 521 and / or the adjusting member 510. Taking the driven rotating part 522b as an example, the mounting end of the adjusting member 510 on the opposite side to the free end is installed in an arcuate shape, and gear teeth 523 are installed on this arcuate part. The gear teeth 523 can be extended to at least a part of the arcuate surface, and the part installed in the arcuate surface constitutes the driven rotating part 522b.

[0166] In another embodiment, at least one of the driving rotating part 522a and the driven rotating part 522b may be an individual member, and may be installed separately from the corresponding driving motor 521 and / or the adjusting member 510, for example, as a gear structure. The respective rotation axes of the driving rotating part 522a and the driven rotating part 522b may be installed in parallel with a gap therebetween, thereby realizing better meshing transmission between the driving rotating part 522a and the driven rotating part 522b.

[0167] In one embodiment, the adjusting member 510 includes a plate-shaped body 511 for being movably installed between the steam inlet 420 and the air inlet 430, and a mounting plate part 512 provided at an end of the plate-shaped body 511 for being rotatably connected to a side wall of the exhaust passage 410. By installing the mounting plate part 512, it is possible to improve the mounting stability between the adjusting member 510 and the inner wall of the exhaust passage 410. The driving member 520 is connected to the mounting plate part 512.

[0168] The outer casing 400 includes a first cavity shell 400a forming the steam inlet 420 and a second cavity shell 400b forming the air inlet 430, and the plate surfaces of the plate-like main body 511 facing the first cavity shell 400a and the second cavity shell 400b are installed, and the middle part of the mounting plate part 512 is rotatably installed on the passage wall of the exhaust passage 410 at the position where it is located, and the plate surface of the mounting plate part 512 fits the passage wall of the exhaust passage 410 at the position where it is located. By installing the mounting plate part 512 in an openwork shape, the mass of the adjustment material 510 on the mounting plate part 512 can be reduced.

[0169] The driving member 520 drives the mounting plate portion 512 to rotate, thereby rotating the plate-shaped main body 511 between the steam inlet 420 and the air inlet 430 .

[0170] Specifically, as described above, the rotating part 522 connected to the driving motor 521 is defined as a driven rotating part 522a, and the rotating part 522 connected to the mounting end of the adjusting member 510 is defined as a driven rotating part 522b. The driven rotating part 522b is coaxially mounted on the mounting plate part 512 and positioned between the mounting plate part 512 and the side wall of the exhaust passage 410 at its location, so that the mounting and rotation of the driven rotating part 522b become more stable.

[0171] In one embodiment, the adjustment material 510 includes a plate-shaped main body 511 and a mounting plate portion 512 provided at an end of the plate-shaped main body 511, the mounting plate portion 512 being rotatably attached to the exhaust passage 410, and the mounting plate portion 512 constituting the mounting end.

[0172] In one embodiment, the adjustment device 500 further includes a stopper structure, i.e., the exhaust system 30 further includes a stopper structure, which is used to position the adjustment material 510 on the outer casing 400 when the adjustment material 510 moves to cover the steam inlet 420 and / or to position the adjustment material 510 on the outer casing 400 when the adjustment material 510 moves to cover the air inlet 430.

[0173] Specifically, the adjusting material 510 has a first plate surface for covering the steam inlet 420, and the stopper structure is used to connect the first plate surface and the outer casing 400 when the adjusting material 510 moves to cover the steam inlet 420, thereby preventing the adjusting material 510 from hitting the outer casing 400 and bouncing back, affecting the covering effect of the first plate surface on the steam inlet 420. And / or, the adjusting material 510 has a second plate surface for covering the air inlet 430, and the stopper structure is used to connect the second plate surface and the outer casing 400 when the adjusting material 510 moves to cover the air inlet 430, thereby preventing the adjusting material 510 from hitting the outer casing 400 and bouncing back, affecting the covering effect of the second plate surface on the air inlet 430.

[0174] In addition, there may be two stopper structures, and when the two stopper structures are installed between the first plate surface and the corresponding inner wall of the exhaust passage 410, and between the second plate surface and the corresponding inner wall of the exhaust passage 410, respectively, the two stopper structures may be installed identically or differently.

[0175] Of course, there are many specific technical proposals for the stopper structure. Taking the stopper structure installed between a first plate surface and the corresponding inner wall of the exhaust passage 410 as an example, the stopper structure may include a connecting portion installed on the first plate surface and a butting portion installed on the corresponding inner wall of the exhaust passage 410.

[0176] In one embodiment, the connecting portion may be an adsorbent material, and the butting portion may be an adhesive fitting material, and the connection between the first plate surface and the corresponding inner wall of the exhaust passage 410 is realized by the adhesive action when the adsorbent material and the adhesive fitting material approach each other, wherein the adsorbent material may be a suction cup, a magnetic structure, etc.

[0177] In one embodiment, the connecting portion may be an adhesive material, and the butting portion may be an adhesive fitting material, and the connection between the first plate surface and the corresponding inner wall of the exhaust passage 410 is realized by the adhesive action when the adhesive material and the adhesive fitting material approach each other, wherein the adhesive material may be a rubber strip or the like that is applicable under the current environment.

[0178] In one embodiment, the connecting portion may be a buckle, and the butting portion may be a buckle fitting, and the connection between the first plate surface and the corresponding inner wall of the exhaust passage 410 is realized by the buckle action when the buckle and the buckle fitting approach each other.

[0179] Of course, when the driving member 520 includes a driving rotating part 522a and a driven rotating part 522b as described above, the gear teeth 523 meshing with each other between the driving rotating part 522a and the driven rotating part 522b realize self-locking of the moving state of the driving rotating part 522a and the driven rotating part 522b when both are not rotating, thereby realizing self-locking of the moving state of the adjusting material 510 and achieving the purpose of avoiding the bouncing of the adjusting material 510 described above, and therefore the driving rotating part 522a and the driven rotating part 522b together constitute the stopper structure.

[0180] 6 and 8, in one embodiment, the adjusting material 510 is installed in a plate shape, and the side of the adjusting material 510 facing the steam inlet 420 and / or the side of the adjusting material 510 facing the air inlet 430 is the abutting side 513, that is, the side on which the first plate surface and / or the second plate surface are located constitutes the abutting side 513. The adjusting material 510 has an elastic sealing layer 513a installed at least on the abutting side 513. For example, when elastic sealing layer 513a is installed on the first plate surface, elastic sealing layer 513a can seal the gap between the first plate surface and the peripheral side of steam inlet 420 when the first plate surface covers steam inlet 420, thereby preventing leakage of steam 901; on the other hand, elastic sealing layer 513a can mitigate the mutual impact between the first plate surface and the peripheral side of steam inlet 420 when the first plate surface covers steam inlet 420, thereby obtaining an impact absorption effect, which contributes to eliminating impact sounds and improves the service life of adjusting material 510 and outer casing 400.

[0181] The elastic sealing layer 513a may be made of an elastic material such as rubber or silicone, and may be molded integrally with the adjusting material 510. For example, at least a first plate surface of the adjusting material 510 is made of an elastic material. Alternatively, the elastic sealing layer 513a is provided separately from the adjusting material 510, and the two are detachably connected. The elastic sealing layer 513a may extend over the entire plate surface of the first plate surface, or may be provided corresponding to the joint between the first plate surface and the outer casing 400.

[0182] Further, in one embodiment, the adjustment material 510 is provided with an engagement protrusion 513b at the middle of the abutment side 513, the engagement protrusion 513b being shaped and sized to fit the corresponding steam inlet 420 or the air inlet 430. The engagement protrusion 513b is used to lock and connect the steam inlet 420 when the adjustment material 510 moves to cover the steam inlet 420, and / or the engagement protrusion 513b is used to engage the air inlet 430 when the adjustment material 510 moves to cover the air inlet 430.

[0183] Similarly, taking the engaging protrusion 513b installed on the first plate surface as an example, the engaging protrusion 513b is engaged within the steam inlet 420 when the first plate surface covers the steam inlet 420, thereby enhancing the covering effect of the first plate surface on the steam inlet 420, which corresponds to forming the above-mentioned stopper structure and contributes to a reliable connection between the adjusting material 510 and the outer casing 400. The engaging protrusion 513b is installed such that its outer surface fits the outer surface shape of the outer casing 400 at that position when it is engaged with the steam inlet 420, so that it is possible to avoid the formation of an unnecessary recess structure on the outer surface of the outer casing 400, which contributes to improving the overall aesthetics.

[0184] As in the above, the engaging protrusion 513b may be formed integrally with the contact side 513, or may be formed separately from the contact side 513. When the elastic seal layer 513a and the engaging protrusion 513b are provided on the contact side 513, the elastic seal layer 513a can spread over the entire plate surface of the contact side 513 and be sandwiched between the engaging protrusion 513b and the contact side 513, or the elastic seal layer 513a is provided in a ring shape along the circumferential side of the engaging protrusion 513b.

[0185] Furthermore, at least the peripheral side wall of the engaging protrusion 513b may be made elastic, so that when the engaging protrusion 513b engages with the steam inlet 420 or the air inlet 430, it can elastically abut against the inner edge of the corresponding steam inlet 420 or air inlet 430, thereby further enhancing the sealing effect and connection strength.

[0186] In one embodiment, the adjusting material 510 is provided with a guide portion, which is movably connected to a fitting portion 480 installed on the exhaust passage 410 and guides the adjusting material 510 to move between the steam inlet 420 and the air inlet 430. The installation of the guide portion and the fitting portion 480 can define an accurate path for the adjustment material 510 to move, and can prevent the adjustment material 510 from shifting sideways and becoming detached during movement.

[0187] Specifically, the guide portion is provided as a sliding protrusion, and is slidably connected to the fitting portion 480 provided as a sliding groove. The extending direction of the sliding groove corresponds to the moving direction of the adjusting member 510. For example, when the adjusting member 510 reciprocates between the steam inlet 420 and the air inlet 430, the sliding groove is provided in a substantially arc shape.

[0188] 6 to 7, in one embodiment, the regulating device 500 further includes a position sensor 600, which is provided in the outer casing 400, specifically, can be installed in the exhaust passage 410, and the position sensor 600 is electrically connected to the control member and can be controlled and operated by the control member. The position sensor 600 is used to sense the position information of the regulating member 510, for example, when the regulating member 510 moves to cover the steam inlet 420, the position sensor 600 transmits a sensing signal to the control member, thereby making it possible to better know whether the steam 901 discharged from the inner tank 20 has entered the exhaust passage 410, and to associate the working states between the exhaust system 30 and the inner tank 20.

[0189] There are many specific technical solutions for the position sensor 600. In one embodiment, the position sensor 600 may be a non-contact sensor, such as an optical sensor, an image recognition sensor, etc. Based on this, the position sensor 600 is installed on the moving path of the adjustment material 510, and when the adjustment material 510 moves to pass the position sensor 600, it is captured by the position sensor 600 to trigger a sensing signal.

[0190] In one embodiment, the position sensor 600 may be a contact sensor, such as a pressure sensor, a stroke switch, etc. Based on this, the position sensor 600 is installed on the abutment side 513 or on the inner wall of the exhaust passage 410 abutting the abutment side 513, so that when the adjustment material 510 moves to cover the steam inlet 420, the position sensor 600 abuts and triggers a sensing signal.

[0191] Taking as an example a case where the position sensor 600 is a contact sensor, specifically, in one embodiment, the adjustment material 510 comprises a plate-shaped main body 511 and a mounting plate portion 512 which is provided at an end of the plate-shaped main body 511, rotatably attached to the exhaust passage 410, and constitutes the mounting end, and the position sensor 600 has an electrical contact 610, and on the side of the mounting plate portion 512 facing the electrical contact 610, a contact protrusion 514 is provided which abuts against the electrical contact 610 when the adjustment material 510 moves to cover the steam inlet 420.

[0192] The installation of the mounting plate portion 512 can enhance the mounting stability between the adjustment material 510 and the inner wall of the exhaust passage 410, and contribute to increasing the moment of the contact protrusion 514, so that when the adjustment material 510 just covers the steam inlet 420, the contact protrusion 514 just abuts against the electrical contact 610, and applies a force to the electrical contact 610, and the position sensor 600 captures the current state and forms a sensing signal.

[0193] Further, in one embodiment, the contact protrusion 514 has a front side close to the electrical contact 610 and a rear side far from the electrical contact 610, and the front wall of the contact protrusion 514 may be inclined or arcuate to form a guide surface, and when the contact protrusion 514 moves toward the electrical contact 610, interference is formed between the contact protrusion 514 and the electrical contact 610, and the amount of interference gradually increases, i.e., the thrust force applied by the contact protrusion 514 to the electrical contact 610 gradually increases.

[0194] 2 and 5, in one embodiment, the adjustment device 500 further includes a sensor 800 including a temperature detection module and a humidity detection module, the sensor 800 is disposed in the exhaust passage 410 and used to respectively detect the temperature and humidity values ​​in the exhaust passage 410. Wherein, the control member is electrically connected to the sensor 800, and controls the adjustment device 500 to operate correspondingly according to a predetermined rule according to the received temperature value and the received humidity value.

[0195] The temperature detection module and the humidity detection module are installed separately and together form one detection module to form the sensor 800. Alternatively, the temperature detection module and the humidity detection module are integrally configured to form the sensor 800.

[0196] The present application also provides an exhaust system 30 including the outer casing 400 and the adjustment device 500 as described above. For the detailed configuration of the adjustment device 500 in the exhaust system 30, please refer to the above-mentioned embodiment of the adjustment device 500, and the description will be omitted here. Since the above-mentioned adjustment device 500 is used in the exhaust system 30 of the present application, the embodiment of the exhaust system 30 of the present application includes all technical solutions of all the embodiments of the adjustment device 500, and the technical effects achieved are also exactly the same, and the description will be omitted here.

[0197] In one embodiment, the outer casing 400 includes a first cavity shell having the steam inlet 420 and a second cavity shell having an air inlet 430, wherein the first cavity shell is flexibly connected to the second cavity shell to define, together with the second cavity shell, a mixing passage segment in the exhaust passage.

[0198] Specifically, referring to Figures 2 and 3, the first cavity shell and the second cavity shell are installed at an incline so as to gradually move away from the exhaust passage 410 in a direction in which they approach each other. In other words, the first cavity shell and the second cavity shell are installed with an intersecting included angle, and the included angle between the sides facing the exhaust passage 410 is less than 180°. By installing in this manner, the flow direction of the steam 901 entering the exhaust passage 410 through the steam inlet 420 and the flow direction of the air 902 entering the exhaust passage 410 through the air inlet 430 are installed so as to gradually approach each other. Therefore, the steam 901 and the air 902 meet and mix more quickly in the mixing passage segment, and the drying effect on the steam 901 is improved.

[0199] Another object of the present application is to provide an air passage structure applicable to an exhaust system of a dishwasher that can be used for washing tableware, cooking utensils, cutlery, etc. With reference to Figs. 1 to 9, the drawings show a specific embodiment in which the air passage structure provided in the present application is applied to an exhaust system 30 of a dishwasher 1.

[0200] 5, the exhaust system 30 provided by the present application includes an air passage structure and an adjustment device 500, in which the exhaust system 30 further includes an adjustment device 500, the air passage structure includes an outer casing 400 in which an exhaust passage 410 is formed, the exhaust passage 410 includes a mixing passage segment 410a and an outlet passage segment 410b which are connected in sequence, and the mixing passage segment 410a is provided with a steam inlet 420 and an air inlet 430. The steam inlet 420 is for communicating with the inner tank 20 of the dishwasher 1, and the air inlet 430 is for taking in the outside air 902.

[0201] The adjustment device 500 is attached to the mixing passage segment 410a and controls the ratio of the steam 901 and the air 902 entering the exhaust passage 410 by adjusting the flow rate of steam 901 entering the exhaust passage 410 through the steam inlet 420 and / or the flow rate of the air 902 entering the exhaust passage 410 through the air inlet 430.

[0202] In the technical solution provided in this application, the adjusting device 500 adjusts the flow rate of the steam 901 entering the exhaust passage 410 from the steam inlet 420 and / or the flow rate of the external air 902 entering the exhaust passage 410 from the air inlet 430, so as to adjust the ratio of the steam 901 and the air 902 in the exhaust passage 410, so that when a large amount of the steam 901 is discharged from the inner tank 20, the flow rate of the steam 901 entering the exhaust passage 410 can be effectively reduced, and sufficient air 902 can be taken into the steam 901 to realize the rapid drying of the steam 901. When a small amount of the steam 901 is discharged from the inner tank 20, the flow rate of the steam 901 into the exhaust passage 410 can be effectively increased, and the drying efficiency of the steam 901 can be improved. The steam inlet 420 and the air inlet 430 are directly connected to the mixing passage segment 410a to directly dry the steam 901 discharged from the inner tank 20, thereby avoiding the formation of a cooling medium and the generation of condensed water in the path where the steam 901 enters the exhaust passage. The technical solution provided in this application not only improves the drying efficiency of the steam 901 discharged from the inner tank 20, but also reduces or eliminates the generation of condensed water, and optimizes the drying effect.

[0203] To promote rapid mixing of the steam 901 and air 902 in the mixing passage segment 410a, the steam inlet 420 of the enclosure 400 is located adjacent to the air inlet 430, defining the mixing passage segment 410a.

[0204] The outer casing 400 is generally provided with an exhaust port 440 communicating with the outlet passage segment 410b so as to exhaust a mixed gas 903 obtained by mixing steam 901 and air 902. Specifically, the steam inlet 420 and the air inlet 430 are installed adjacent to one end of the mixing passage segment 410a remote from the outlet passage segment 410b, and the exhaust port 440 is installed at the other end of the outlet passage segment 410b remote from the mixing passage segment 410a, thereby appropriately lengthening the flow path length of the mixed gas 903 and achieving sufficient drying of the steam 901 by the air 902.

[0205] The exhaust passage 410 is not limited in the extending direction relative to the housing 10, and may extend horizontally, vertically, or in any other direction. When the exhaust passage 410 extends vertically, the mixing passage segment 410a and the blowing passage segment 410b communicate with each other from top to bottom, which contributes to increasing the exhaust speed of the mixed gas 903 to some extent.

[0206] 2-3, in one embodiment, the outer casing 400 includes a first cavity shell 400a provided with the steam inlet 420 and a second cavity shell 400b provided with the air inlet 430, in which the first cavity shell 400a is bent and connected to the second cavity shell 400b, and the mixing passage segment 410a is defined between the first cavity shell 400a and the second cavity shell 400b. When installed in this manner, steam 901 entering the exhaust passage 410 through the steam inlet 420 and air 902 entering the exhaust passage 410 through the air inlet 430 are mixed uniformly in the mixing passage segment 410a after passing along or flowing through the bent connection point.

[0207] Specifically, the first cavity shell 400a and the second cavity shell 400b form an included angle on the side facing the mixing passage segment 410a, and the included angle is less than 180°. That is, the first cavity shell 400a and the second cavity shell 400b are installed at an incline so as to gradually move away from the exhaust passage 410 in a direction in which they approach each other, and the flow direction of the steam 901 entering the exhaust passage 410 through the steam inlet 420 and the flow direction of the air 902 entering the exhaust passage 410 through the air inlet 430 are installed so as to gradually approach each other, so that the steam 901 and the air 902 meet and mix more quickly in the mixing passage segment 410a, and the drying effect on the steam 901 is improved.

[0208] 2 to 3 and 5, in one embodiment, the outer wall of the outer casing 400 is recessed inward to form a bulging portion 460' in the exhaust passage 410, the outside of the bulging portion 460' covers the exhaust port 21 of the inner tank 20, and the steam inlet 420 is provided on the side wall of the bulging portion 460'. By being installed in this manner, it is possible to improve the versatility of the air passage structure in the dishwasher 1 of different specifications, and the bulging portion 460' can change the direction of the steam 901 exhausted through the exhaust port 21 of the inner tank 20 and then guide the steam 901 from the steam inlet 420 into the exhaust passage 410, so that the position design of the steam inlet 420 and the air inlet 430 in the exhaust system 30 is not limited by the installation position of the exhaust port 21 of the inner tank 20, which contributes to improving the versatility of the air passage configuration.

[0209] Furthermore, in one embodiment, the bulge 460' has at least a portion of the side wall formed in an arc shape. By forming the side wall in the arc shape, the steam 901 passing through the bulge 460' can be smoothly guided, and the steam 901 can enter the steam inlet 420 more smoothly.

[0210] In addition, the outer casing 400 can also install an air guide structure 470 in the exhaust passage 410, and the specific form of the air guide structure 470 can be various, for example, an air guide plate installed adjacent to the steam inlet 420 and / or the air inlet 430, or an arc-shaped segment formed on the inner wall of the exhaust passage 410, which guides the steam 901 and the air 902 to mix rapidly, and prevents the steam 901 from drying late and condensing on the inner wall of the exhaust passage 410 to generate condensed water.

[0211] In one embodiment, the outer housing 400 includes a first housing 401 and a second housing 402, the mixing passage segment 410a is formed in the first housing 401, the blowing passage segment 410b is at least partially formed in the second housing 402, and the first housing 401 is detachably connected to the second housing 402.

[0212] In addition, the mixing passage segment 410a is formed in the first housing 401, and the steam inlet 420 and the air inlet 430 are installed at one end of the first housing 401 away from the second housing 402, so that steam 901 entering the exhaust passage 410 via the steam inlet 420 and air 902 entering the exhaust passage 410 via the air inlet 430 can be quickly mixed in the mixing passage segment 410a.

[0213] By forming a part of the blow-off passage segment 410b in the first housing 401 and the remaining part in the second housing 402, the length of the mixing passage segment 410a can be made as short as possible, and the steam 901 immediately after entering the mixing passage segment 410a can be quickly mixed and quickly dried, thereby achieving the purpose of preventing the generation of condensation water.

[0214] Furthermore, in one embodiment, at least a part of the connection between the mixing passage segment 410a and the blowing passage segment 410b transitions in an arc shape. The arc-shaped transition portion can form a smooth guide surface, and the steam 901 and the air 902 in the mixing passage segment 410a can be guided and mixed and then smoothly enter the blowing passage segment 410b, thereby preventing the gas from violently colliding with the inner wall of the exhaust passage 410 and generating noise.

[0215] In view of the above, the present application further provides an exhaust system 30, the exhaust system 30 including the above-mentioned air passage configuration and an adjustment device 500, the adjustment device 500 being mounted within the mixing passage segment 410a and controlling the ratio of the steam 901 and the air 902 entering the exhaust passage 410 by adjusting the flow rate of steam entering the exhaust passage 410 via the steam inlet 420 and / or the flow rate of air 902 entering the exhaust passage 410 via the air inlet 430.

[0216] For details of the air passage configuration in the exhaust system 30, please refer to the above-mentioned embodiment of the air passage configuration, and the description will be omitted here. Since the above-mentioned air passage configuration is used in the exhaust system 30 of the present application, the embodiment of the exhaust system 30 of the present application includes all technical solutions of all the embodiments of the above-mentioned air passage configuration, and the technical effects achieved are exactly the same, so the description will be omitted here.

[0217] Specifically, the mounting end of the adjustment member 510 can be installed to be rotatable along a rotation axis extending in a direction substantially perpendicular to the connecting wall 450, so that the plate surface of the adjustment member 510 slides approximately along the surface on which the connecting wall 450 is located. Based on this, one free end can be installed to individually block the steam inlet 420 or the air inlet 430 in one rotation process, or two free ends can be installed, and the two free ends are located on opposite sides of the mounting end and are substantially blade-shaped.

[0218] 2 and 3, the mounting end of the adjusting material 510 can be installed to be rotatable along a rotation axis extending in a direction substantially parallel to the connecting wall 450 so that the plate surface of the adjusting material 510 rotates relative to the surface on which the connecting wall 450 is located. By installing in this manner, the adjusting material 510 surrounds the mixing passage segment 410a of the steam 901 and / or air 902 together with the inner wall of the exhaust passage 410 on the opposite side during the rotation process, and the mixing passage segment 410a is installed to gradually expand along the direction of the airflow, thereby sufficiently diffusing the steam 901 and / or air 902 while the steam 901 and / or air 902 are flowing, and contributing to rapid mixing of the steam 901 and the air 902.

[0219] Further, in one embodiment, the control material 510 has an attachment end and a free end arranged opposite to each other as described above, the attachment end is rotatably connected between the steam inlet 420 and the air inlet 430, and the free end is close to the communicating part between the mixing passage segment 410a and the blowing passage segment 410b. By installing in this manner, it contributes to shortening the length of the mixing passage segment 410a as much as possible, and the steam 901 entering the exhaust passage 410 through the steam inlet 420 and the air 902 entering the exhaust passage 410 through the air inlet 430 are mixed immediately after passing through the control material 510, quickly dried, and no condensation water is generated.

[0220] The present application also provides a dishwasher 1, which includes a housing 10, an inner tank 20, and an exhaust system 30. For a detailed configuration of the exhaust system in the dishwasher 1, please refer to the above-mentioned embodiment of the exhaust system 30, and a detailed description thereof will be omitted here. Since the above-mentioned exhaust system 30 is used in the dishwasher 1 of the present application, the embodiment of the dishwasher 1 of the present application includes all technical solutions of all the embodiments of the above-mentioned exhaust system 30, and the technical effects achieved are exactly the same, and a detailed description thereof will be omitted here.

[0221] Further, the present application provides a method for controlling a dishwasher. With reference to FIGS. 10 to 15, specific embodiments of the method for controlling a dishwasher provided in the present application are shown in the drawings.

[0222] Referring to FIG. 10, in a first embodiment of the dishwasher control method provided by the present application, a dishwasher 1 is provided, in which the dishwasher 1 includes a housing 10, an inner tank 20, and an exhaust system 30. The exhaust system 30 provided by the present application includes an outer casing 400 and an adjustment device 500. The outer casing 400 is provided with an exhaust passage 410, a first intake port 420, and a second intake port 430, in which the first intake port 420 and the second intake port 430 are respectively connected to the exhaust passage 410, and the first intake port 420 is connected to the inner tank 20 of the dishwasher 1 to allow the first gas discharged from the inner tank 20 to flow through the exhaust passage 410. The first intake port 420 is used to take in a gas 901, the second intake port 430 is used to take in a second gas 902 having a lower humidity than that of the first gas 901, and the regulating device 500 includes an regulating mechanism 500 and a control member, and the regulating mechanism 500 is configured to control the ratio of the first gas 901 and the second gas 902 entering the exhaust passage 410 by regulating, under the control of the control member, the flow rate of the first gas 901 entering the exhaust passage 410 through the first intake port 420 and the flow rate of the second gas 902 entering the exhaust passage 410 through the second intake port 430.

[0223] In addition, the control member can realize the intelligent operation of the adjustment mechanism according to a predetermined rule or actual need, and the adjustment mechanism can adjust the flow rate of the first gas 901 entering the exhaust passage 410 from the first intake port 420 and the flow rate of the second gas 902 entering the exhaust passage 410 from the second intake port 430, respectively, to adjust the ratio of the first gas 901 and the second gas 902 in the exhaust passage 410. When a large amount of the first gas 901 is discharged from the inner tank 20, the flow rate of the first gas 901 entering the exhaust passage 410 can be effectively reduced, and sufficient second gas 902 can be taken into the first gas 901 to realize rapid drying of the first gas 901. In addition, when a small amount of the first gas 901 is discharged from the inner tank 20, the flow rate of the first gas 901 to the exhaust passage 410 can be effectively increased, and the drying efficiency of the first gas 901 can be improved. In addition, the first intake port 420 is directly connected to the exhaust passage 410, so that the first gas 901 discharged from the inner tank 20 can be directly dried, and the formation of a cooling medium on the path through which the first gas 901 enters the exhaust passage and the generation of condensed water can be avoided. The technical solution provided in this application not only improves the drying efficiency of the first gas 901 discharged from the inner tank 20, but also reduces or eliminates the generation of condensed water, and optimizes the drying effect.

[0224] It should be noted that the embodiment of the dishwasher 1 includes all the technical solutions of all the embodiments of the exhaust system 30, and the technical effects achieved are also exactly the same, so they will not be repeated here.

[0225] Based on this, the dishwasher control method includes the following steps:

[0226] In step S10, the adjustment mechanism 500 is controlled to cover the first air inlet 420 when the dishwasher 1 is in the washing stage.

[0227] In this embodiment, the control unit can monitor whether the dishwasher 1 is in the washing stage in various ways, for example, it can be determined whether a related command transmitted from a control system already installed in the dishwasher 1 is received, or the operating state in the inner tank 20 can be detected by a separately installed detection device. When the dishwasher 1 is in the washing stage, it is necessary to form sufficient steam in the inner tank 20 to obtain a desired washing effect, and the adjustment mechanism is controlled to cover the first air inlet 420 to block the first gas 901 from entering the exhaust passage 410 through the first air inlet 420, that is, to prevent the first gas 901 in the inner tank 20 from flowing out to the outside, to reduce heat loss, and to prevent condensation in the exhaust passage 410 to generate condensed water.

[0228] In step S20, when the dishwasher 1 is in the exhaust stage, the adjustment mechanism 500 is controlled to open the first air inlet 420 and the second air inlet 430 respectively, thereby controlling the ratio of the first gas 901 and the second gas 902 entering the exhaust passage 410.

[0229] Specifically, when the dishwasher 1 is in the exhaust stage and the amount of steam is large, the control member controls the adjustment mechanism to control the flow areas of the first intake port 420 and the second intake port 430, respectively, so that the first gas 901 and the second gas 902 enter the exhaust passage 410, respectively, and the ratio between the first gas 901 and the second gas 902 is within an appropriate range, so that the first gas 901 has a sufficient exhaust amount, and the second gas 902 dries the first gas 901 quickly, and avoids the generation of condensed water. When the dishwasher 1 is in the exhaust stage and the amount of steam drops to a predetermined value, the control member controls the adjustment mechanism to adjust the first intake port 420 to be fully open, so that the first gas 901 enters the exhaust passage 410 at a maximum flow rate, thereby realizing the quick exhaust of the first gas 901.

[0230] Referring to FIG. 11, in a second embodiment of the dishwasher control method provided by the present application, as described above, the dishwasher 1 further includes a sensor 800 and a first fan 700 arranged in the exhaust passage 410, and the sensor 800 includes a humidity sensing module.

[0231] Wherein, when the first fan 700 is installed in the exhaust passage 410 and electrically connected to the control member, the sensor 800 may be installed upstream or downstream of the first fan 700, i.e., it may be installed on the side farther from the exhaust port 440 or on the side closer to the exhaust port 440 according to actual needs.

[0232] At this time, when the dishwasher 1 is in the exhaust stage, the above step S20 of controlling the adjustment mechanism to open the first air inlet 420 and the second air inlet 430, respectively, and controlling the ratio of the first gas 901 and the second gas 902 entering the exhaust passage 410 includes the following steps.

[0233] In step S21, when the dishwasher 1 is in the exhaust stage, the adjustment mechanism 500 is controlled to open the first air inlet 420 and the second air inlet 430, respectively, and the first fan 700 is controlled to operate at a first predetermined rotation speed.

[0234] In this embodiment, as described above, the adjustment mechanism adjusts the flow area of ​​each of first air inlet 420 and second air inlet 430, thereby making it possible to adjust the ratio of first gas 901 and second gas 902 in exhaust passage 410 to an appropriate range. Furthermore, by turning on first fan 700, the rotation speed of first fan 700 can be controlled to reach a first predetermined rotation speed, and the gas in exhaust passage 410 can be driven to circulate, forming a large exhaust volume, which contributes to improving the drying effect of dishwasher 1.

[0235] In step S22, the humidity value of the exhaust passage 410 is obtained.

[0236] The humidity value can be sensed by a humidity sensing module installed in the exhaust passage 410. The humidity value is the humidity of the gas in the exhaust passage 410, i.e., the humidity of the mixed gas 903 in which the first gas 901 and the second gas 902 are mixed, and can intuitively reflect the drying effect of the exhaust passage 410.

[0237] In step S26, when the humidity value falls to the target humidity threshold, the rotation speed of the first fan 700 is adjusted to a second predetermined rotation speed that is lower than the first predetermined rotation speed.

[0238] It should be noted that the humidity value is a real-time measured value, and as the exhaust passage 410 continues to operate, the humidity value will gradually decrease. When the humidity value decreases to the target humidity threshold, it indicates that the current drying effect of the dishwasher 1 has already achieved the target drying effect or is close to the target drying effect. At this time, the amount of first gas 901 flowing into the exhaust passage 410 is relatively small, and the amount of second gas 902 required is reduced. Therefore, the rotation speed of the first fan 700 is adjusted to decrease, the exhaust speed in the exhaust passage 410 is reduced, and the residence time of the second gas 902 in the exhaust passage 410 is increased, thereby achieving sufficient drying of the first gas 901 in the exhaust passage 410 and contributing to saving energy loss.

[0239] In addition, the above-mentioned first predetermined rotation speed, second predetermined rotation speed, and target humidity threshold value can be determined according to actual needs, such as using factory default values ​​or being customized and set by the user.

[0240] Referring to FIG. 12, in a third embodiment of the dishwasher control method provided by the present application, as described above, the dishwasher 1 further includes a second fan and a heater provided in the inner tank 20, among which the second fan is provided in the inner tank 20 and drives the flow of gas in the inner tank 20 to make the first gas 901 enter the exhaust passage 410 more quickly. The second fan is electrically connected to the control member and can be operated under the control of the control member. The heater is provided in the inner tank 20 and can heat the gas in the inner tank 20 to form a desired hot air. The heater is electrically connected to the control member and can be operated under the control of the control member.

[0241] In the above step S26, if the humidity value falls to the target humidity threshold, before adjusting the rotation speed of the first fan 700 to a second predetermined rotation speed which is lower than the first predetermined rotation speed, the method further includes the following steps.

[0242] In step S23, when the humidity value drops to the first humidity threshold, the second fan is adjusted to operate at its predetermined minimum speed.

[0243] In this embodiment, when the humidity value falls to the first humidity threshold, the second gas 902 in the exhaust passage 410 becomes greater than the first gas 901, so the second fan in the inner tank 20 is started first, and the first gas 901 in the inner tank 20 is quickly exhausted into the exhaust passage 410 by the second fan to be sufficiently mixed with the second gas 902. At this time, the flow rate of the second gas 902 relatively decreases, so the second fan is operated at a predetermined minimum rotation speed to slow down the flow rate of the first gas 901, thereby ensuring in advance a sufficient time for mixing the first gas 901 and the second gas 902, and contributing to a reduction in the energy consumption of the second fan.

[0244] In step S24, when the humidity value is smaller than the first humidity threshold and larger than the second humidity threshold, the rotation speed of the second fan is controlled to be increased stepwise, where the first humidity threshold, the second humidity threshold, and the target humidity threshold are successively smaller.

[0245] In this embodiment, when the humidity value decreases from the first humidity threshold to a value sufficiently close to the second humidity threshold, the second gas 902 in the exhaust passage 410 becomes greater than the first gas 901, and at this time, the rotation speed of the second fan may be gradually increased to introduce more of the first gas 901 into the exhaust passage 410 and mix it with the second gas 902, making full use of the drying ability of the second gas 902 and contributing to the rapid discharge of the first gas 901 in the inner tank 20.

[0246] In step S25, when the humidity value is smaller than the first humidity threshold and larger than the second humidity threshold, and the rotation speed of the second fan reaches a predetermined maximum rotation speed, the heater is operated and the rotation speed of the first fan 700 is controlled to be reduced.

[0247] In this embodiment, when the rotation speed of the second fan reaches the maximum but the humidity does not reach the second humidity threshold, the heater can be controlled to operate, and the heater can cooperate with the second fan to directly start drying the first gas 901 from the inner tank 20, and the first gas 901 that enters the exhaust passage 410 from the inner tank 20 has already achieved a certain degree of drying, and at this time, the rotation speed of the first fan 700 can be appropriately adjusted to decrease, which contributes to extending the residence time of the first gas 901 and the second gas 902 in the exhaust passage 410, thereby achieving complete drying of the first gas 901 and completely eliminating the generation of condensed water, and also reducing energy consumption to achieve energy saving.

[0248] Referring to FIG. 13, in a fourth embodiment of the dishwasher control method provided by the present application, based on the above, the sensor 800 further includes a temperature sensing module used to sense the temperature value in the exhaust passage 410, and the sensor 800 is installed in the exhaust passage 410, and in step S26, if the humidity value drops to the target humidity threshold, the rotation speed of the first fan 700 is adjusted to a second predetermined rotation speed which is smaller than the first predetermined rotation speed, and then the following steps S27 to S28 are included.

[0249] In step S27, the temperature value of the exhaust passage 410 is obtained.

[0250] In step S28, if the temperature value is greater than a predetermined temperature threshold, the first fan 700, the second fan, and the heater are controlled to be turned off, and after a set time, the first fan 700 and the second fan are controlled to operate at their respective predetermined maximum rotation speeds, and the heater is controlled to operate.

[0251] In addition, the temperature sensing module senses the temperature value in the exhaust passage 410 in real time, and if the temperature value is greater than a predetermined temperature threshold, the current temperature in the exhaust passage 410 is sufficient to dry the remaining first gas 901 in the exhaust passage 410, and therefore, in consideration of energy saving, the first fan 700, the second fan and the heater can be controlled to be turned off.

[0252] While the first fan 700, the second fan, and the heater are off, the first gas 901 enters the exhaust passage 410 at a constant flow rate and gradually increases the humidity in the exhaust passage 410. Therefore, after a predetermined time, the first fan 700 and the second fan are controlled to operate at their respective predetermined maximum rotation speeds and the heater is controlled to operate, thereby making it possible to more quickly and completely dry the first gas 901.

[0253] Referring to FIG. 14, in a fifth embodiment of the dishwasher control method provided by the present application, after obtaining the temperature value of the exhaust passage 410 in step S27, the method further includes steps S29 to S30.

[0254] In step S29, if the temperature value is equal to or lower than the predetermined temperature threshold value, the heater is controlled to be turned off, and the first fan 700 and the second fan are controlled to operate at their respective predetermined maximum rotation speeds.

[0255] In step S30, after the dishwasher 1 satisfies a predetermined condition, the first fan 700 and the second fan are controlled to be turned off.

[0256] In this embodiment, when the temperature value is below a predetermined temperature threshold but the humidity value has reached or is sufficiently close to the target humidity value, indicating that the drying effect in the exhaust passage 410 is approaching the target drying requirement, the heater is controlled to be turned off to save energy, and the first fan 700 and the second fan are controlled to operate at their respective predetermined maximum rotation speeds to dry the first gas 901 more quickly and completely.

[0257] After the dishwasher 1 satisfies a predetermined condition, the first fan 700 and the second fan are controlled to be turned off. The predetermined condition may be when the first fan 700 and the second fan are operated for a predetermined time, or when it is determined that both the humidity value and the temperature value satisfy a predetermined threshold value by continuing to detect the humidity value and the temperature value in the exhaust passage 410, and is not limited thereto.

[0258] Next, referring to FIG. 15, in a sixth embodiment of the dishwasher control method provided by the present application, the first gas 901 discharged from the inner tank 20 can be dried by reducing the energy consumption based on the maximum humidity.

[0259] 1 to 9, the mounting end of the adjusting material 510 can be installed rotatably along a rotation axis extending in a direction substantially parallel to the connecting wall 450 so that the plate surface of the adjusting material 510 rotates relative to the surface on which the connecting wall 450 is located. The dishwasher 1 includes the first fan 700, a second fan, and a heater.

[0260] The first air intake port 420 and the second air intake port 430 are installed so that the planes in which they are located intersect; that is, in the above, the first air intake port 420 and the second air intake port 430 are installed at an incline so as to gradually move away from the exhaust passage 410 in the direction in which they approach each other.

[0261] Based on the above, if the included angle between the plane on which the second air intake 430 is located and the plane on which the first air intake 420 is located is set to 70°, and the adjustment material 510 is set to cover the second air intake 430 before cleaning begins, then when cleaning begins, the adjustment material 510 is controlled to rotate 70° toward the first air intake 420, so that the first air intake 420 is completely covered by the adjustment material 510, energy loss within the inner tank 20 is avoided, and the second air intake 430 is fully opened.

[0262] When the cleaning process is completed and the exhaust stage is started, the first fan 700 is first controlled to be turned on up to a predetermined maximum rotation speed to ensure that the exhaust passage 410 is sufficiently filled with the second gas 902, and then the regulator 510 is controlled to open the first intake port 420, so that the first gas 901 discharged through the inner tank 20 enters the exhaust passage 410 and is mixed with the second gas 902. At this time, since the flow rate of the first gas 901 is significantly smaller than the flow rate of the second gas 902, the first gas 901 that has entered the exhaust passage 410 can be quickly dried by the second gas 902, and the generation of condensed water can be avoided.

[0263] At this time, the current humidity value of the exhaust passage 410 can be sensed, and if the humidity value is less than 88%, the adjustment member 510 is rotated in stages to gradually open the first intake port 420, for example, every 10° of rotation angle, so that the flow rate of the first gas 901 gradually increases and the flow rate of the second gas 902 gradually decreases.

[0264] When the first air inlet 420 is fully open and the humidity value is still below 88%, the second fan can be turned on while the rotation speed of the first fan 700 is maintained at a predetermined maximum rotation speed. The second fan initially operates at a predetermined minimum rotation speed, and if the humidity value remains below 88%, the rotation speed of the second fan is increased stepwise in this order to a predetermined intermediate rotation speed and then to a predetermined maximum rotation speed.

[0265] When the first fan 700 and the second fan are operated at their respective predetermined maximum rotation speeds and the humidity value is still less than 88%, the heater can then be turned on and operated. At this time, the heater can achieve a good drying effect by increasing the gas temperature. Therefore, in consideration of energy saving, the first fan 700 can be adjusted to its predetermined minimum rotation speed so that the first gas 901 and the second gas 902 are sufficiently retained and mixed in the exhaust passage 410.

[0266] Then, if the humidity value is less than 70% and the temperature value is greater than 35° C., the first fan 700, the second fan and the heater can be controlled to be turned off for 5 minutes, for example, to continue drying the first gas 901 with residual heat. After 5 minutes, the first fan 700 and the second fan can be controlled to operate at their respective predetermined maximum rotation speeds, and the heater can be turned on to maintain the humidity value below 70%.

[0267] Conversely, when the humidity value is less than 70% and the temperature value is equal to or lower than 35°C, the first fan 700 and the second fan can be controlled to operate at their respective predetermined maximum rotation speeds, and then turned off after achieving sufficient drying.

[0268] After each step of the above flow, the state at that time can be set to be maintained for a certain period of time, and the specific length of time is not limited, for example, 10 seconds as shown in the figure. In addition, the predetermined minimum rotation speed, the predetermined intermediate rotation speed and the predetermined maximum rotation speed of the first fan 700 and the second fan may be set to be the same or at least partially different. Of course, the numerical values ​​in the above embodiment do not limit the operating parameters of the actual operation of the dishwasher 1, and can be adjusted according to the situation.

[0269] After the exhaust system 30 is applied to the dishwasher 1, the control member installed as a controller can be installed integrally with the control system already installed in the dishwasher 1. That is, at least a part of the above-mentioned control functions of the control member can be realized by the control system already installed in the dishwasher 1. Alternatively, the control member installed as a controller can be installed separately from the control system already installed in the dishwasher 1, and each control function can be realized independently. When the exhaust system 30 requires signal transmission with the dishwasher 1, the control member can be electrically connected to the control system.

[0270] The control member may include, but is not limited to, a memory, a processor, and a dishwasher control program stored in the memory and executable on the processor, the dishwasher control program being configured to implement the steps of the dishwasher control method described above.

[0271] The present application also provides a storage medium storing a dishwasher control program that realizes the steps of the above-mentioned dishwasher control method by a processor. All memories, processors, and storage media capable of realizing the above-mentioned functions are applicable to the present specification and are not limited thereto. The storage medium is, for example, a computer storage medium that can include an operating system, a network communication module, a user interface module, and a dishwasher control program, and will not be described in detail.

[0272] The above is merely a preferred embodiment of the present application, and does not limit the scope of the claims of the present application. In the inventive concept of the present application, the equivalent structural modifications made using the contents of the specification of the present application and the attached drawings, or those directly / indirectly applied in other related technical fields, are also included in the scope of the claims of the present application.
