[0012] The present invention is further configured such that, in step two, if there is no drying step in the dishwashing program, the dishwasher performs pre-wash, main wash, cold rinse and other processes according to the selected program, and finally ends the dishwashing process, and the steam elimination module does not start.

[0013] The present invention is further configured such that the steam elimination module includes an air supply device, an air supply pipe and an air outlet pipe. The air supply device is connected to the air outlet pipe through the air supply pipe and is used to supply air toward the air outlet pipe. The air outlet pipe is located at the opening edge of the dishwasher inner tub and has several air outlet holes facing the front side of the dishwasher.

[0014] The present invention is further configured such that the steam elimination module also includes an air supply section and a valve assembly. The air supply section is located inside the dishwasher inner tub, connected to the air supply pipe, and has an air outlet. The air supply pipe is divided into a branch line one and a branch line two. Branch line one connects to the air outlet pipe, and branch line two connects to the air supply section. The valve assembly is located inside the air supply pipe and is used to control the on / off state of branch line one and branch line two.

[0015] The present invention is further configured such that the valve assembly has three states: a first state cuts off branch one and connects branch two; a second state cuts off branch two and connects branch one; and a third state connects both branch one and branch two simultaneously.

[0016] The present invention is further configured such that the valve assembly includes a valve plate and a driver, one end of the valve plate is rotatably connected to the air supply pipe via a valve shaft, and the valve shaft is driven to rotate by the driver; the valve shaft is located between branch one and branch two, the valve plate rotates toward branch one to close branch one, and the valve plate is in a first state; the valve plate rotates toward branch two to close branch two, and the valve plate is in a second state; the valve plate is positioned between branch one and branch two to simultaneously open branch one and branch two, and the valve plate is in a third state.

[0017] The present invention is further configured such that the air outlet pipe includes an upper air outlet section with an air outlet hole, the upper air outlet section being located on the upper side of the opening and arranged along the edge of the opening; the air outlet pipe also includes a side air outlet section one and a side air outlet section two with an air outlet hole, the side air outlet section one and the side air outlet section two being located on the left and right sides of the opening and arranged along the edge of the opening.

[0018] The present invention is further configured such that the two ends of the upper air outlet section are respectively connected to the upper ends of the first side air outlet section and the second side air outlet section, and the lower end of the second side air outlet section is connected to the air supply pipe; the first side air outlet section is provided with an air guide plate, which divides the first side air outlet section into a channel one and a channel two, the channel one being connected to the air outlet hole of the first side air outlet section, and the channel two being connected to the upper air outlet section.

[0019] The present invention is further configured such that a baffle plate is connected to the upper end of the air guide plate, the baffle plate is inclined, and a notch is formed at the end of the channel away from the air supply pipe; a baffle plate is provided at the connection between the upper air outlet section and the side air outlet section, the baffle plate is inclined, and a notch is formed between the upper air outlet section and the side air outlet section.

[0020] The present invention is further configured such that a baffle plate is fixed at the bottom of the inner cavity of the air supply section. The baffle plate is located between the air outlet and the air supply pipe and is higher than the lower edge of the air outlet to prevent water from flowing back into the air duct.

[0021] In summary, the present invention has the following beneficial effects:

[0022] The valve assembly allows for switching between the on / off states of branch line one and branch line two, enabling control over their operation and thus switching the air outlet state of the air duct and the air supply section. This allows for various air outlet state adjustments to accommodate different steam dissipation conditions.

[0023] When the dishwasher door is opened during the wash and dry phase, the air supply system activates, directing air through the air duct into the exhaust duct. Air then exits from the top and sides of the inner drum opening, blowing the steam emanating from the inner drum towards the front of the dishwasher, forcing the steam away from the countertop and cabinets. Simultaneously, the air intake unit within the inner drum further directs airflow, allowing the steam to dissipate quickly. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] This embodiment discloses a steam elimination module at the outlet of a dishwasher, such as... Figure 1-2 As shown, the system includes an air supply device 4, an air supply duct 5, an air outlet duct 6, and a valve assembly 10. The air supply device 4 is a fan installed in the direction of airflow and has an air outlet end. The air outlet end of the air supply device 4 is connected to the air outlet duct 6 through the air supply duct 5, and can supply air towards the air outlet duct 6. The air outlet duct 6 is a hollow strip structure and is arranged along the edge of the opening 11 of the dishwasher inner tub 1. Furthermore, a plurality of air outlet holes 64 are provided on the front side 65 of the air outlet duct 6, and each air outlet hole 64 is arranged along the edge of the opening 11.

[0038] During the drying stage of the final washing cycle, when the dishwasher door is opened, humid air escapes from the opening 11. The air supply device 4 delivers air into the air outlet duct 6 through the air supply pipe 5. The air outlet 64 on the front side of the air outlet duct 6 discharges air outward from the opening 11. By outputting air from each air outlet 64, airflow is generated along the edge of the opening 11 of the inner tub 1, facing the front of the dishwasher. This airflow blows the steam emanating from the inner tub 1 directly in front of the machine, forcing the steam away from the work surface and cabinets, thus preventing the hot and humid air from affecting the work surface and cabinets.

[0039] like Figure 1-3 As shown, the steam elimination module 3 also includes an air supply unit 7, which is located inside the dishwasher inner tub 1 and has a hollow air guide structure. It can send a portion of the air volume output by the air supply device 4 into the dishwasher inner tub 1, increasing the airflow within the inner tub 1 and allowing the steam in the inner tub 1 to dissipate as quickly as possible. The air outlet pipe 6 along the edge of the opening 11 can blow the dissipated hot and humid steam towards the front of the dishwasher, thereby forcing the steam away from the work surface and cabinets and accelerating the elimination of the effects of steam escape.

[0040] Specifically, the air outlet duct 6 includes an upper air outlet section 62, which is located above the opening 11 along its edge. Several air outlet holes 64 are also provided on the front side 65 of the upper air outlet section 62, arranged laterally along its length, forming a relatively dense upper air outlet area above the opening 11. During air outlet operation, the upper air outlet section 62 blows air towards the front side 65 of the dishwasher, directing the steam from the inner tank 1 directly in front of the machine. Simultaneously, it forms an air curtain-like structure above the opening 11, creating a barrier to prevent the rising steam and avoiding direct impact of high-temperature, high-humidity air on the work surface and cabinets.

[0041] Furthermore, the air outlet duct 6 mainly outlets air along the upper edge and the left and right sides of the opening 11, and also includes a first side outlet section 61 and a second side outlet section 63. The first side outlet section 61 and the second side outlet section 63 are respectively arranged along the left and right sides of the opening 11, and several air outlet holes 64 are opened on the front side 65 of the first side outlet section 61 and the second side outlet section 63. The air outlet holes 64 are arranged vertically along the length of the first side outlet section 61 and the second side outlet section 63, forming a relatively dense side outlet area on both sides of the opening 11.

[0042] During the air discharge process, the first side air outlet section 61 and the second side air outlet section 63 can blow air towards the front side 65 of the dishwasher, blowing the steam emitted from the inner tub 1 to the front of the machine. On the other hand, they form an air curtain structure on the left and right sides of the opening 11, which forms a barrier to the rising steam and prevents the high temperature and high humidity air from escaping and directly affecting the cabinets or other facilities on the left and right sides of the dishwasher.

[0043] Specifically, the two ends of the upper air outlet section 62 are respectively connected to the upper ends of the first side air outlet section 61 and the second side air outlet section 63, and the three air outlet sections of the air outlet duct 6 are connected to form a whole. Among them, the lower end of the first side air outlet section 61 is connected to the air supply duct 5, so that each section of the air outlet duct 6 can be connected to the air supply device 4, and the air supply device 4 can simultaneously supply air to each air outlet section.

[0044] In order to ensure that the airflow in the outlet duct 6 is relatively evenly distributed and that the airflow in each outlet section is evenly distributed, an air guide structure can be installed in the inner cavity of each section of the outlet duct 6 to guide the incoming airflow.

[0045] like Figure 3 , 4 As shown, a guide vane 611 is provided inside the side air outlet section 61. The guide vane 611 is distributed along the length of the side air outlet section 61, dividing it into channel 1 612 and channel 2 613. Channel 1 612 is close to the front of the dishwasher and is connected to the air outlet 64 of the side air outlet section 61. The airflow entering the channel 1 612 can be output from the air outlet 64 of the air outlet section 61. Channel 2 613 is connected to the upper air outlet section 62 and supplies air to the upper air outlet section 62 and the side air outlet section.

[0046] Since channel 1 612 mainly supplies air to side outlet section 1 61, and channel 2 613 supplies air to top outlet section 62 and side outlet section 2 63, the inner diameter of channel 1 612 is smaller than that of channel 2 612, so that the air volume of each outlet section is relatively uniform.

[0047] A baffle plate 614 is connected to the upper end of the air guide plate 611. The baffle plate 614 is inclined and tilted towards the front side 65. Under the air guiding effect of the baffle plate 614, it helps to block the wind and make the wind blowing out of the front section of the side air outlet section 61 stronger. At the same time, a notch 615 is formed at the upper end of the baffle plate 614. Through the notch 615, excess air can reach the top of the channel 612 and continue to flow towards the upper air outlet section 62.

[0048] like Figure 8 , 9 As shown, a baffle plate 621 is installed at the connection between the upper air outlet section 62 and the second side air outlet section 63. The baffle plate 621 is fixedly connected to the rear wall of the inner cavity of the air outlet pipe 6, extends towards the second side air outlet section 63, and is inclined towards the front side 65. Due to the obstruction of the baffle plate 621, a gap 622 is formed between the upper air outlet section 62 and the second side air outlet section 63, which helps to block the wind and allows more airflow to be blocked in the upper air outlet section 62, resulting in a stronger wind blowing out of the upper air outlet section 62. At the same time, under the action of the gap 622 between the upper air outlet section 62 and the second side air outlet section 63, excess air can reach the second side air outlet section 63, forming a side airflow.

[0049] The air supply section 7 has an air outlet 71 facing the interior of the inner liner 1 and is connected to the air supply duct 5, allowing a portion of the air to be supplied into the inner liner 1. The air supply duct 5 is divided into branch 1 81 and branch 2 82 by a partition plate 8. Branch 1 81 connects to the air outlet duct 6, and branch 2 82 connects to the air supply section 7. A valve assembly 10 is installed inside the air supply duct 5, which controls the on / off state of branch 1 81 and branch 2 82, thereby switching the air outlet states of the air outlet duct 6 and the air supply section 7 and enabling various air outlet state adjustments.

[0050] The partition plate 8 is disposed in the inner cavity of the air supply duct 5, forming arc-shaped surfaces 83 facing branch 1 81 and branch 2 82 respectively. It can smoothly guide the airflow, help reduce the wind speed in the air supply duct 5, and maintain the smoothness of the airflow. Furthermore, the partition plate 8 is fixed in the inner wall of the air supply duct 5, forming a reinforcing rib structure, thereby increasing the strength performance of the air supply duct 5.

[0051] like Figure 2 As shown, a baffle 72 is installed on the outside of the air outlet 71. The baffle 72 has several filter holes, which allow for smooth airflow and prevent impurities in the inner cavity from entering the air outlet 71, thus playing a blocking and protective role. Specifically, the baffle 72 can be installed at the air outlet 71 with a threaded structure, and a washer 73 maintains the stability of the connection of the baffle 72.

[0052] like Figure 3 As shown, a baffle plate 9 is fixed at the bottom of the inner cavity of the air supply section 7. The baffle plate 9 is located between the air outlet 71 and the air supply pipe 5, which can prevent water from flowing into the air duct during the rinsing process. In addition, the upper edge of the baffle plate 9 is higher than the lower edge of the air outlet 71, so that the water entering the air supply section 7 can flow back into the dishwasher inner tub 1.

[0053] When the dishwasher door is opened during the washing and drying stage, the air supply device 4 blows some air into the inner tub 1 so that the steam in the inner tub 1 can be released as soon as possible. At the same time, another part is transmitted through the air supply pipe 5 to the air outlet pipe 6, and the air is discharged on the upper side and the left and right sides of the opening 11, blowing the steam released from the inner tub 1 to the front side 65 of the dishwasher, forcing the steam away from the work surface and cabinet.

[0054] like Figure 3 , 5 As shown in Figure 7, the valve assembly 10 has three states. The first state cuts off branch 1 81 and connects branch 2 82, as shown in Figure 7. Figure 5 As shown; in the second state, branch 2 82 is disconnected, and branch 1 81 is connected, as follows. Figure 6 As shown; in the third state, branch 1 (81) and branch 2 (82) are simultaneously connected, as follows: Figure 7 As shown.

[0055] The valve assembly 10 includes a valve plate 101 and a actuator. The valve plate 101 is driven by the actuator, and the valve plate 101 switches between three states during operation. The valve assembly 10 can be driven by various actions such as rotation or movement.

[0056] Specifically, one end of the valve plate 101 is rotatably connected to the air supply pipe 5 via a valve shaft 102. The valve shaft 102 is driven to rotate by a driver, which can be a motor, and the angle position of the valve plate 101 can be adjusted. The valve shaft 102 is located between branch 1 81 and branch 2 82, and is located at the lower end of the partition plate 8.

[0057] When valve plate 101 rotates toward branch 81, branch 81 is closed, and valve plate 101 is in the first state. At this time, the air outlet pipe 6 will be cut off, and the air supply section 7 will be opened, allowing outside air to enter the inner liner 1 through the air duct and mix, thereby reducing the steam in the inner liner 1.

[0058] When valve plate 101 rotates toward branch 2 82, branch 2 82 is closed, and valve plate 101 is in the second state. At this time, air outlet 6 will be opened and air supply 7 will be cut off, allowing outside air to pass through air outlet 6. The air outlet 6 with the inner opening 11 can partially discharge air, blowing the dispersed steam away from the work surface or cabinet.

[0059] When valve plate 101 is oriented between branch line 1 81 and branch line 2 82, branch line 1 81 and branch line 2 82 are opened simultaneously, and valve plate 101 is in the third state. At this time, air outlet duct 6 and air supply section 7 simultaneously discharge air, which can send outside air into the inner liner 1, accelerate the dissipation of steam in the inner liner 1, and blow the dispersed steam away from the work surface or cabinet through air outlet duct 6.

[0060] This embodiment also discloses a dishwasher, such as Figure 10 As shown, the system includes an inner liner 1, a door 2, and a steam elimination module 3 as described in the above embodiment. In the steam elimination module 3, an air supply device 4 is installed in the base of the dishwasher, and an air supply pipe 5 extends along the side wall interlayer of the dishwasher inner liner, supplying air to the air outlet pipe 6. The air outlet pipe 6 forms an air outlet area on the upper side of the opening of the inner liner 1 and on the left and right sides, blowing away the high-temperature and high-humidity gas escaping from the inner liner.

[0061] This embodiment also discloses an intelligent steam elimination control method for a dishwasher, which uses the aforementioned steam elimination module 3 and includes the following steps:

[0062] Step 1: The dishwasher starts washing dishes according to the washing program;

[0063] Step 2: Determine if a drying step is present in the dishwashing program. If no drying step is present in the dishwashing program, the dishwasher will perform pre-wash, main wash, cold rinse, and other processes according to the selected program, and finally end the dishwashing process. The steam elimination module 3 will not be activated.

[0064] If the dishwashing program includes a drying step, the dishwasher will perform pre-wash, main wash, and rinsing processes according to the selected program, and the steam elimination module 3 will be activated.

[0065] Step 3: After entering the drying stage, the dishwasher door 2 is closed, and the rotary motor control valve is in state one; at this time, the air outlet 6 will be cut off, and the air supply 7 will be opened, so that the outside air can enter the inner tank 1 through the air duct and mix, so that the steam in the inner tank 1 is reduced, and the drying time is T0min.

[0066] Step 4: When door 2 is opened, the rotary motor controls the valve plate to state 2; at this time, the air outlet pipe 6 will be opened and the air supply section 7 will be cut off, allowing outside air to pass through the air outlet pipe 6. The air outlet pipe 6 with the inner opening 11 can partially discharge air, blowing the dispersed steam away from the work surface or cabinet for a duration of T1min.

[0067] Step 5: While door 2 remains open, rotate the motor control valve to state 3; at this time, air outlet 6 and air supply 7 simultaneously blow air, which can send outside air into the inner liner 1, accelerate the dissipation of steam in the inner liner 1, and speed up the drying of tableware and inner wall; at the same time, the air in air outlet 6 blows out from the top and left and right sides of the inner liner 1, blowing the dispersed steam away from the work surface or cabinet, for a duration of T2min.

[0068] This dishwasher not only effectively removes high-temperature steam from the inner tank 11, accelerating the drying of tableware, but also ensures that the airflow area at the dishwasher opening 11 keeps the steam away from the countertop and cabinets, reducing their corrosive effects, minimizing user losses, and enhancing the user experience.

[0069] In addition, the drying times T0, T1, and T2 in different washing programs can be obtained using the following experimental methods and incorporated into the corresponding washing programs.

[0070] First, according to the corresponding washing program, obtain multiple sets of standard tableware of the same number. Place each set of standard tableware into a dishwasher with the corresponding specifications and parameters for multiple washes. The dishwasher's status parameters include water intake, rinsing time, number of rinsing cycles, motor speed, drying time, etc., which can be set individually. Then, obtain the dishwasher's status parameters during each wash and the drying parameters of the standard tableware after each wash. Finally, based on the dishwasher's status parameters and washing parameters, generate the required times T0, T1, and T2 for the dishwasher's drying stage, select appropriate values, and input them into the corresponding program. This ensures that steam dissipation is achieved during the drying stage in subsequent use.

[0071] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
