Description

Technical Field

[0001] The present invention belongs to the technical field of dishwashers, and in particular relates to a dishwasher exhaust assembly and a dishwasher having the exhaust assembly. Background Art

[0002] With the improvement of living standards, people have higher and higher requirements for the quality of life, and thus have higher and higher requirements for product quality, performance, user-friendly use, intelligent operation and other aspects. As an excellent product, dishwashers have gradually entered people's lives. Dishwashers are devices that automatically wash bowls, chopsticks, plates, dishes, knives, forks and other tableware, greatly facilitating people's lives. After washing the tableware, the dishwasher usually needs to dry the tableware. Among the existing dishwashers, some use waste heat to dry the tableware, while others use additional drying systems to dry the tableware. The drying system can be an exhaust system, which exhausts the humid air inside the dishwasher to the outside through the exhaust system to achieve the purpose of drying. The exhaust vent area of existing dishwashers cannot be adjusted, which causes a lot of water vapor to be discharged from the exhaust vent during the dishwasher cleaning process, taking away a lot of energy and causing energy loss.

[0003] The air volume adjustment in the existing dishwasher air duct is generally achieved by increasing or decreasing the wind speed in the air duct using a speed-controlled fan. Currently, there are also technologies for adjusting the exhaust air volume. For example, Chinese patent application number CN201910073169.2 discloses an air duct structure for a dishwasher and a dishwasher having such an air duct structure, which includes a accommodating chamber for holding items to be washed; an exhaust channel connected to the accommodating chamber of the dishwasher and used to discharge the gas in the accommodating chamber out of the dishwasher; an adjustment component disposed in the exhaust channel and used to open and close the exhaust channel and\or adjust the exhaust volume of the exhaust channel; the adjustment component includes a first adjustment unit disposed in the exhaust channel and capable of connecting or disconnecting the exhaust channel from the accommodating chamber; and a second adjustment unit connected to the first adjustment unit and providing power for the movement of the first adjustment unit. The present invention provides an air duct structure for a dishwasher and a dishwasher having the air duct structure. By setting the exhaust port of the exhaust duct to be adjustable in size, the exhaust port area is reduced to a minimum during the washing stage of the dishwasher, thereby reducing heat loss and maintaining the temperature; and the exhaust port area is opened to a maximum during the drying stage of the dishwasher, thereby increasing the passage of air.

[0004] In this patent, the exhaust duct's outlet is configured to be adjustable in size. Simultaneously with the outlet's size adjustment, the speed of the speed-regulating fan also needs to be adjusted, and the air volume needs to be monitored to ensure that the air volume matches the fan power and maintains optimal operating conditions. This results in a complex structure with numerous components. Furthermore, the manufacturing and assembly of any component have certain deviations, resulting in slight deviations in the correspondence between the fan power and air volume, which in turn prevents the fan from operating optimally.

[0005] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Summary of the Invention

[0042] See also Figures 1-8 , is the first embodiment of the dishwasher exhaust assembly proposed by the present invention. A dishwasher exhaust assembly is used to exhaust air from the dishwasher's washing chamber. The exhaust assembly includes an exhaust duct 10, a fan 20, and an air volume adjustment structure 30. The exhaust duct 10 is used to exhaust air from the dishwasher's washing chamber. The fan 20 is disposed on the exhaust duct 10 and is used to drive the air in the exhaust duct 10 to be discharged. The air volume adjustment structure 30 is used to direct air from outside the washing chamber into the exhaust duct 10, so that the power of the fan 20 matches the air volume discharged from the washing chamber. The exhaust duct 10 includes a front duct section 11 located between the washing chamber and the fan 20, and a rear duct section 12 connected to the air outlet 21 of the fan 20. The air volume adjustment structure 30 is disposed in the front duct section 11. Both air exhausted from the washing chamber and air entering through the air volume adjustment structure 30 flow into the fan 20 and are then discharged through the rear duct section 12.

[0043] By setting up an air volume regulating structure, the gas outside the cleaning room is introduced into the exhaust duct 10, so that the power of the fan 20 matches the air volume discharged from the cleaning room; when the air volume discharged from the cleaning room remains unchanged, the air volume of the gas outside the cleaning room entering the exhaust duct 10 can be adjusted by adjusting the air volume regulating structure 30, so that the total amount of gas entering the fan 20 can be adjusted, and the power of the fan 20 can be adjusted to match the air volume discharged from the cleaning room, so that the fan 20 works under good working conditions, which is beneficial to improving the life of the fan 20.

[0044] See also Figure 2 As shown, the air volume adjustment structure 30 includes an auxiliary air inlet 31 provided in the front section 11 of the air duct, and an air volume adjustment plate 32 that can adjust the size of the auxiliary air inlet 31. By providing the auxiliary air inlet 31, air can enter the front section 11 of the air duct; moving the air volume adjustment plate 32 can adjust the size of the auxiliary air inlet 31, thereby adjusting the amount of air entering. An adjustment slide 33 that matches the air volume adjustment plate 32 is provided in the auxiliary air inlet 31, and the air volume adjustment plate 32 is movably located within the adjustment slide 33; moving the air volume adjustment plate 32 can adjust the size of the auxiliary air inlet 31.

[0045] See also Figure 2 and Figure 4 As shown, in order to detect the air volume entering the exhaust duct 10 from the cleaning room, a detection plate 40 for detecting the air volume is provided between the air inlet of the front section 11 of the air duct and the auxiliary air inlet 31. The detection plate 40 has a detection body 41 extending into the front section 11 of the air duct and capable of swinging with the wind, and a pointer 42 extending out of the front section 11 of the air duct is provided on the detection body 41. The detection body 41 is hingedly provided on the front section 11 of the air duct. The gas coming out of the cleaning chamber passes through the front section 11 of the air duct, pushing the detection body 41 to rotate, causing the pointer 42 to swing. The upper end of the detection body 41 is hinged, and the detection body 41 is vertically drooping under normal conditions, with the pointer 42 pointing downward. When the air volume in the front section 11 of the air duct is large, the angle of rotation of the detection body 41 is large, causing the pointer 42 to swing at a large angle. When the air volume in the front section 11 of the air duct is small, the angle of rotation of the detection body 41 is small, causing the pointer 42 to swing at a small angle. Therefore, by observing the swing angle of the pointer 42, the size of the air volume entering the front section 11 of the air duct from the cleaning chamber can be intuitively obtained. When the power of the fan 20 is small, that is, at a certain speed of the fan 20, the size of the auxiliary air inlet 31 can be changed by pushing and pulling the air volume adjustment plate 32, so that the air volume entering the front section 11 of the air duct from the cleaning chamber matches the power of the fan 20. By observing the pointer 42 to judge the air volume, and manually adjusting the air volume adjustment plate 32 to adjust the size of the external air intake, the exhaust assembly of the present invention has a simple structure and convenient adjustment operation.

[0046] See also Figure 8As shown, the direction of gas flow in the exhaust duct 10 is fixed, and the lower end of the detection body 41 is bound to swing toward the auxiliary air inlet 31 under the influence of the air flow. To prevent gas from flowing in the exhaust duct 10 in the opposite direction when the exhaust assembly is not working, a limiting rib 112 is provided in the front section 11 of the duct to limit the swing of the detection body 41 toward the air inlet 111 of the front section 11 of the duct.

[0047] Regarding the installation of the detection plate 40, an installation opening 113 for installing the detection plate 40 is provided in the front section 11 of the air duct, and a cover plate 50 is provided on the outside of the installation opening 113.

The detection plate 40 is inserted downward from the upper end of the installation opening 113, so that the detection body 41 extends into the front section 11 of the air duct. Hinge columns 43 are provided on both sides of the upper end of the detection body 41. The hinge columns 43 are located on both sides of the installation opening 113. The hinge columns 43 near the pointer 42 connect the pointer 42 and the detection body 41. The installation opening 113 is a strip-shaped opening, and the extension direction of the installation opening 113 is the width direction of the front section 11 of the air duct. A retaining edge 51 is provided along the side of the cover plate 50 near the pointer 42, which is bent and extended in the direction of the pointer 42. The pointer 42 extends out of the retaining edge 51 to facilitate observation of the pointer 42. Preferably, the detection plate 40 is made of a transparent material.

[0048] A fixed slide 114 is provided outside the installation opening 113, and the cover plate 50 is installed on the fixed slide 114 to prevent wind from entering from the installation opening 113. An upwardly inclined claw 52 is provided at one end of the cover plate 50 away from the retaining edge 51, and the claw 52 is engaged with the end of the fixed slide 114 away from the pointer 42.

[0049] See also Figures 9-12 、 Figure 5 and Figure 6 1 is a second embodiment of the dishwasher exhaust assembly proposed by the present invention. The main difference between this embodiment and the first embodiment is that a motor is provided for driving the air volume adjustment plate 32, and the rest of the structure can be the same as that of the first embodiment.

[0050] A dishwasher exhaust assembly is used to exhaust air from the dishwasher's wash chamber. The exhaust assembly includes an exhaust duct 10, a fan 20, and an air volume adjustment structure 30. The exhaust duct 10 is used to exhaust air from the dishwasher's wash chamber. The fan 20 is located on the exhaust duct 10 and drives the air in the exhaust duct 10 to be exhausted. The air volume adjustment structure 30 is used to direct air from outside the wash chamber into the exhaust duct 10, so that the power of the fan 20 matches the air volume exhausted from the wash chamber. The exhaust duct 10 includes a front duct section 11 located between the wash chamber and the fan 20, and a rear duct section 12 connected to the air outlet 21 of the fan 20. The air volume adjustment structure 30 is located in the front duct section 11. Both air exhausted from the wash chamber and air entering through the air volume adjustment structure 30 flow into the fan 20 and are then exhausted through the rear duct section 12.

[0051] By setting up an air volume regulating structure, the gas outside the cleaning room is introduced into the exhaust duct 10, so that the power of the fan 20 matches the air volume discharged from the cleaning room; when the air volume discharged from the cleaning room remains unchanged, the air volume of the gas outside the cleaning room entering the exhaust duct 10 can be adjusted by adjusting the air volume regulating structure 30, so that the total amount of gas entering the fan 20 can be adjusted, and the power of the fan 20 can be adjusted to match the air volume discharged from the cleaning room, so that the fan 20 works under good working conditions, which is beneficial to improving the life of the fan 20.

[0052] See also Figure 10 As shown, the air volume adjustment structure 30 includes an auxiliary air inlet 31 provided in the front section 11 of the air duct, and an air volume adjustment plate 32 that can adjust the size of the auxiliary air inlet 31. By providing the auxiliary air inlet 31, air can enter the front section 11 of the air duct; moving the air volume adjustment plate 32 can adjust the size of the auxiliary air inlet 31, thereby adjusting the amount of air entering. An adjustment slide 33 that matches the air volume adjustment plate 32 is provided in the auxiliary air inlet 31, and the air volume adjustment plate 32 is movably located within the adjustment slide 33; moving the air volume adjustment plate 32 can adjust the size of the auxiliary air inlet 31.

[0053] The air volume adjustment structure also includes a motor 34 for driving the air volume adjustment plate 32. This movement of the motor 34 causes the air volume adjustment plate 32 to move. A sensor 60 for detecting air volume is located between the air inlet 111 of the front section 11 of the air duct and the auxiliary air inlet 31. By controlling the sensor 60 and the power of the motor 34, the motor 34 is driven to move, causing the auxiliary air inlet 31 to change in size, thereby adjusting the amount of auxiliary air intake. This helps to match the power of the fan 20 with the air volume discharged from the cleaning chamber, and ensures that the fan 20 operates in optimal conditions.

[0054] In this embodiment, a detection plate 40 may also be provided to verify the feedback value of the sensor 60 and ensure the accuracy of the air volume detection data. Preferably, the sensor 60 is located between the air inlet 111 of the front section 11 of the air duct and the auxiliary air inlet 31. A detection plate 40 for detecting the air volume is provided between the air inlet and the auxiliary air inlet 31 of the front section 11 of the air duct. The detection plate 40 comprises a detection body 41 extending into the front section 11 of the air duct and capable of swinging with the wind, and a pointer 42 extending out of the front section 11 of the air duct. The detection body 41 is hingedly provided on the front section 11 of the air duct. The gas coming out of the cleaning chamber passes through the front section 11 of the air duct, pushing the detection body 41 to rotate, causing the pointer 42 to swing. The upper end of the detection body 41 is hinged, and the detection body 41 is vertically drooping under normal conditions. When the air volume in the front section 11 of the air duct is large, the angle of rotation of the detection body 41 is large, causing the pointer 42 to swing at a large angle. When the air volume in the front section 11 of the air duct is small, the angle of rotation of the detection body 41 is small, causing the pointer 42 to swing at a small angle. Therefore, by observing the swing angle of the pointer 42, the size of the air volume entering the front section 11 of the air duct from the cleaning chamber can be intuitively obtained. When the power of the fan 20 is small, that is, at a certain speed of the fan 20, the size of the auxiliary air inlet 31 can be changed by pushing and pulling the air volume adjustment plate 32, so that the air volume entering the front section 11 of the air duct from the cleaning chamber matches the power of the fan 20. By observing the pointer 42 to judge the air volume, and manually adjusting the air volume adjustment plate 32 to adjust the size of the external air intake, the exhaust assembly of the present invention has a simple structure and convenient adjustment operation.

[0055] The direction of gas flow within the exhaust duct 10 is fixed, and the lower end of the detection body 41 is bound to swing toward the auxiliary air inlet 31 under the influence of the airflow. To prevent gas from flowing in the exhaust duct 10 in the opposite direction when the exhaust assembly is not operating, a limiting rib 112 is provided in the front section 11 of the duct to limit the swing of the detection body 41 toward the air inlet 111 of the front section 11 of the duct.

Hinge columns 43 are provided on both sides of the upper end of the detection body 41. The hinge columns 43 are located on both sides of the installation opening 113. The installation opening 113 is a strip-shaped opening, and the extension direction of the installation opening 113 is the width direction of the front section 11 of the air duct. A retaining edge 51 is provided along the side of the cover plate 50 close to the pointer 42, which is bent and extended in the direction of the pointer 42. The pointer 42 extends out of the retaining edge 51 to facilitate observation of the pointer 42. Preferably, the detection plate 40 is made of a transparent material.

[0057] A fixed slide 114 is provided outside the installation opening 113, and the cover plate 50 is installed on the fixed slide 114 to prevent wind from entering from the installation opening 113.
