Description

Technical Field

[0001] This utility model relates to the field of kitchen utensils technology, specifically to an integrated cleaning device. Background Technology

[0002] To improve kitchen space utilization, integrated cleaning devices have emerged in household kitchens. For example, the Chinese invention patent "Integrated Dishwasher" disclosed in patent application number CN202310352709.7 (publication number CN116369809A) mainly includes a sink, an overflow component, and the dishwasher body. The integrated dishwasher also includes an exhaust fan installed within an exhaust duct. The exhaust duct includes a return water section located near the cleaning chamber, with the exhaust fan positioned on the side of the return water section away from the cleaning chamber. The return water section guides the condensate back into the cleaning chamber. The exhaust fan can be located within a guide section, and the return water section can be inclined downwards or vertically. Hot, humid gas flows upwards along the return water section, forming condensate during this flow. This condensate flows downwards along the return water section and back into the cleaning chamber to prevent leakage.

[0003] Condensation is easily generated during airflow in the exhaust pipe; therefore, the exhaust duct of this patent has a water return section. Figure 1 As can be seen, the vent and overflow holes of the sink are both located on the right side of the dishwasher body. This allows for the connection between the sink and the dishwasher body with a shorter exhaust pipe, and also makes it easier for condensate to flow back into the dishwasher body.

[0004] However, for some integrated dishwashers, the exhaust vent and the overflow drain of the sink are located on opposite sides of the dishwasher body. This necessitates a relatively long exhaust duct with bends to connect the dishwasher body and the sink. Bends in the exhaust duct can obstruct airflow. Furthermore, with long and bend-filled exhaust ducts, condensation can easily form at the diameter change points, further exacerbating the exhaust obstruction. Additionally, the condensation can be blown around during exhaust, creating bubbling noise. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an integrated cleaning device that allows for smooth airflow discharge, in light of the current state of the technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: an integrated cleaning device, including a water tank, wherein the water tank is provided with an air inlet that communicates with its interior;

[0007] A dishwasher, wherein the dishwasher is provided with an exhaust vent that communicates with its interior;

[0008] Exhaust duct, used to connect the exhaust port and the air inlet port;

[0009] The feature is that the air inlet and the air outlet are located on different sides of the central axis of the dishwasher in the left-right direction. The exhaust pipe has at least one bend for vertical and horizontal connection. At least one bend has an exhaust transition structure with an increased cross-sectional area relative to the exhaust pipe. The exhaust transition structure has an air inlet and an air outlet. The plane where the air outlet end face is located is taken as the reference plane. A straight line intersecting the center line of the air inlet and parallel to the reference plane is taken as the reference line. The intersection point of the reference line and the center line of the air inlet is called the first point. The point where the center line of the air outlet is located on the air outlet end face is called the second point. The angle between the line connecting the first point and the second point and the reference line is between 45° and 135°.

[0010] Preferably, the exhaust pipe includes a first pipe body and a second pipe body. One end of the first pipe body is connected to the exhaust port and the other end is connected to the air inlet. One end of the second pipe body is connected to the air outlet and the other end is connected to the air inlet. The flow area of ​​the air outlet is larger than that of the air inlet, and the flow area of ​​the second pipe body is larger than that of the first pipe body. In this way, the airflow velocity decreases when the air flows out of the air outlet. The condensate generated in the second pipe body can flow into the exhaust transition structure after it accumulates. Due to the reduction in air velocity, the risk of abnormal noise caused by the condensate droplets jumping up and down under the action of hot air is avoided.

[0011] Preferably, the cross-sectional area of ​​the first tube is elliptical. The larger elliptical area increases the flow rate of gas and reduces the problem of gas leaking out of the dishwasher door due to increased pressure inside the dishwasher.

[0012] Preferably, at least half of the length of the first tube is in contact with the wall of the dishwasher; and / or, the exhaust transition structure is at least partially in contact with the wall of the dishwasher, so that the temperature of the dishwasher inner tub is transferred to the first tube and / or the exhaust transition structure, reducing the amount of condensate from steam condensation.

[0013] To facilitate the return of condensate in the second pipe to the exhaust transition structure, the second pipe extends vertically at least partially.

[0014] To facilitate processing, transportation, and subsequent maintenance, the second pipe body is detachably connected to the exhaust transition structure, allowing the second pipe body and the exhaust transition structure to be detached before the integrated cleaning device is assembled.

[0015] In order to allow the second pipe body and the exhaust transition structure to be detachably connected, the exhaust transition structure is provided with a connector, the second pipe body is inserted into the connector, and the two are detachably connected by a connecting structure.

[0016] In the above design, the first pipe body includes a horizontally extending section and a vertically extending section. The lower end of the vertical section is connected to the exhaust port, and the upper end of the vertical section is connected to the air inlet of the horizontal section. The horizontal section is located between the dishwasher and the sink, and the air outlet of the horizontal section is connected to the air inlet. This structural form of the first pipe body ensures smooth airflow, minimizes bends in the exhaust pipe, and keeps the exhaust pipe as short as possible.

[0017] In order to guide the airflow from the air inlet to the air outlet, the exhaust transition structure is provided with guide ribs for guiding the airflow from the air inlet to the air outlet.

[0018] In the above scheme, the exhaust transition structure is arranged vertically, with the air inlet located at the upper part of the exhaust transition structure and the air outlet located on the side wall of the exhaust transition structure and adjacent to the water outlet. The guide ribs are inclined from top to bottom toward the air outlet and divide the exhaust transition structure into an upper space and a lower space. Both the air inlet and the air outlet are located in the upper space, and the water outlet is located on the bottom wall of the exhaust transition structure. The upper space and the lower space are connected by the gap between the lower end of the guide ribs and the side wall of the exhaust transition structure.

[0019] The condensate can be drained directly to the outside through the drain hole, or the drain hole can be connected to the washing chamber or base of the dishwasher through a drain pipe. This allows the condensate to be drained into the washing chamber or to evaporate on the base.

[0020] Compared with the prior art, the advantages of this utility model are as follows: By setting an exhaust transition structure with an increased cross-sectional area relative to the exhaust pipe at the bending part, the flow area at this part is large and the exhaust is smooth. The exhaust transition structure has an air inlet and an air outlet, and the air outlet is set at an angle of 45° to 135° relative to the air inlet. This further allows the airflow to flow smoothly when passing through the bending part. In addition, the exhaust transition structure can also collect condensate water, preventing condensate water from accumulating in the exhaust pipe and producing abnormal noise when blown by the airflow.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] like Figures 1-7 As shown, the integrated cleaning device of this preferred embodiment includes a water tank 1, a dishwasher 2, an exhaust pipe, and an exhaust transition structure 3.

[0030] The sink 1 has an air inlet 11 that communicates with its interior, and the dishwasher 2 has an exhaust vent that communicates with its interior. An exhaust pipe connects the exhaust vent and the air inlet 11. In this embodiment, the air inlet 11 is located on the rear side wall of the sink 1, and the dishwasher 2 is located directly below the sink 1. The air inlet 11 and the exhaust vent are located on different sides of the central axis of the dishwasher 2 in the left-right direction. The central axis refers to a straight line that runs vertically through the center of the dishwasher 2.

[0031] The exhaust duct has at least one bend for vertical and horizontal connection, and at least one bend is provided with an exhaust transition structure 3 that is larger than the cross-sectional area of ​​the exhaust duct. The exhaust transition structure 3 has an air inlet 31, an air outlet 32 ​​and a water outlet 33.

[0032] like Figure 3 , 4 As shown, the exhaust pipe includes a first pipe body 4 and a second pipe body 5. One end of the first pipe body 4 is connected to the exhaust port and the other end is connected to the air inlet 31. One end of the second pipe body 5 is connected to the air outlet 32 ​​and the other end is connected to the air inlet 11. Specifically, the first pipe body 4 includes a horizontally extending horizontal section 41 and a vertically extending vertical section 42. The lower end of the vertical section 42 is connected to the exhaust port, and the upper end of the vertical section 42 is connected to the air inlet end of the horizontal section 41. The horizontal section 41 extends in the left and right direction and is located between the dishwasher 2 and the sink 1. The air outlet end of the horizontal section 41 is connected to the air inlet 31. The connection between the horizontal section 41 and the second pipe body 5 is the bend where the exhaust transition structure 3 is installed.

[0033] Better, such as Figure 7 As shown, the plane where the air outlet end face of the air inlet 31 is located is taken as the reference plane, and the straight line that intersects the center line L1 of the air inlet 31 and is parallel to the reference plane is taken as the reference line L2. The intersection point of the reference line L2 and the center line L1 of the air inlet 31 is called the first point. The point where the center line L3 of the air outlet 32 ​​is located on the air outlet end face of the air outlet 32 ​​is called the second point. The angle α between the line L4 connecting the first point and the second point and the reference line L2 is between 45° and 135°, so that the airflow can flow smoothly when passing through the bend. In addition, the exhaust transition structure 3 can also collect condensate water to prevent condensate water from accumulating in the exhaust pipe and producing abnormal noise after being blown by the airflow.

[0034] The centerline L1 of the air inlet 31 refers to the straight line passing through the center of the air inlet 31 along the direction of airflow, and the centerline L3 of the air outlet 32 ​​refers to the straight line passing through the center of the air outlet 32 ​​along the direction of airflow.

[0035] The flow area of ​​the air outlet 32 ​​is larger than that of the air inlet 31, and the flow area of ​​the second pipe 5 is larger than that of the first pipe 4. This reduces the airflow velocity as the air flows out of the air outlet 32. The condensate generated in the second pipe 5 accumulates and flows into the exhaust transition structure 3. Due to the reduced airflow velocity, the risk of abnormal noise caused by the condensate droplets bobbing up and down under the action of the hot air is avoided. In this embodiment, the cross-sectional area of ​​the air inlet 31 is flat, and the cross-sectional area of ​​the air outlet 32 ​​is circular.

[0036] The air outlet 32 ​​is inclined from top to bottom toward the interior of the exhaust transition structure 3 so that the condensate in the exhaust pipe flows into the exhaust transition structure 3 and finally flows out from the water outlet 33.

[0037] The cross-sectional area of ​​the first tube 4 is elliptical. The larger elliptical structure increases the flow rate of gas and reduces the problem of gas leaking out of the door gap of the dishwasher 2 due to increased pressure inside the dishwasher 2.

[0038] The first pipe body 4 has at least half its length in contact with the wall of the dishwasher 2; and / or, the exhaust transition structure 3 is at least partially in contact with the wall of the dishwasher 2, so that the temperature of the dishwasher 2 is transferred to the first pipe body 4 and / or the exhaust transition structure 3, thereby reducing the amount of condensate from steam condensation.

[0039] In addition, the second pipe body 5 extends vertically at least partially to allow condensate in the second pipe body 5 to flow back to the exhaust transition structure 3.

[0040] In order to guide the airflow from the air inlet 31 to the air outlet 32, the exhaust transition structure 3 is provided with a guide rib 34 for guiding the airflow from the air inlet 31 to the air outlet 32. The exhaust transition structure 3 is arranged vertically, with the air inlet 31 located at the upper part of the exhaust transition structure 3 and the air outlet 32 ​​located on the side wall of the exhaust transition structure 3 and adjacent to the water outlet 33. The guide rib 34 is inclined from top to bottom toward the air outlet 32 ​​and divides the exhaust transition structure 3 into an upper space and a lower space 36. The air inlet 31 and the air outlet 32 ​​are both located in the upper space 35, and the water outlet 33 is located on the bottom wall of the exhaust transition structure 3. The upper space 35 and the lower space 36 are connected through the gap between the lower end of the guide rib 34 and the side wall of the exhaust transition structure 3. After the airflow enters through the air inlet 31, it flows towards the air outlet 32 ​​under the guidance of the guide rib 34. The condensate formed flows from the gap between the lower end of the guide rib 34 and the side wall of the exhaust transition structure 3 to the water outlet 33, and is finally discharged from the water outlet 33.

[0041] The condensate can be discharged directly to the outside through the drain hole 33, or the drain hole 33 can be connected to the washing chamber or base of the dishwasher 2 through the drain pipe 7, so that the condensate can be discharged into the washing chamber or discharged to the base to evaporate.

[0042] The second pipe body 5 is detachably connected to the exhaust transition structure 3. The exhaust transition structure 3 is provided with a connector 6, and the second pipe body 5 is inserted into the connector 6. The two are detachably connected by a connecting structure, allowing the second pipe body 5 and the exhaust transition structure 3 to be detached before the integrated cleaning device is assembled. The connecting structure can be an existing rotation limiting structure, including an L-shaped slot and a locking block that can be locked in the slot; or, the connecting structure can be a screw.
