Abstract
Description
Technical Field
[0001] This utility model relates to a kitchen appliance, specifically to an exhaust pipe for an integrated cleaning device and the integrated cleaning device itself. Background Technology
[0002] To improve kitchen space utilization, integrated cleaning device structures have emerged in household kitchens. For example, the Chinese utility model patent disclosed in patent application number CN202323526906.0 (publication number CN222018267U), entitled "An Exhaust Structure for an Integrated Cleaning Device," describes an integrated cleaning device comprising a sink assembly and a dishwasher located beneath it. The sink assembly includes a sink and a sink washer arranged side-by-side. The dishwasher is located beneath the sink, and a breather connected to the dishwasher's washing chamber is installed on the side wall opposite to the sink washer. The bottom of the breather has a condensate drain outlet, and the top of the breather is connected to an exhaust pipe for steam discharge. An air inlet connected to the exhaust pipe is opened on the side wall of the sink. The exhaust pipe includes a first section, a second section, and a third section. The first section is vertically arranged outside the side wall of the dishwasher and the sink washer, opposite to each other, and is located above the breather. The second section extends horizontally close to the top wall of the dishwasher. The third section is vertically arranged and its upper end extends into the gap formed between the sink and the sink washer, thus connecting with the air inlet.
[0003] Although the patent has a reasonable layout for the exhaust pipe, because the exhaust pipe is long, the temperature difference between the inside and outside of the machine causes a small amount of water vapor to condense into water droplets and remain in the exhaust pipe as the machine runs, especially at the bends. Since the inside of the bends is smooth and there is no water storage device, and there is a continuous airflow through the exhaust pipe, the small water droplets will move up and down with the airflow and produce sound. In addition, the exhaust pipe is connected to the overflow outlet of the water tank, which amplifies the sound of blowing water and brings a bad user experience. Utility Model Content
[0004] The first technical problem to be solved by this utility model is to provide an exhaust pipe for an integrated cleaning device with low noise during exhaust, in light of the current state of the technology.
[0005] The second technical problem to be solved by this utility model is to provide an integrated cleaning device that applies the above-mentioned exhaust pipe, in view of the current state of the prior art.
[0006] The technical solution adopted by this utility model to solve the first technical problem mentioned above is as follows: an exhaust pipe for an integrated cleaning device, characterized in that it includes a first pipe body for communicating with the washing chamber of a dishwasher and a second pipe body for communicating with a water tank. The first pipe body includes a transversely extending transverse section and an inclinedly extending inclined section. The first end of the transverse section and the first end of the inclined section are connected. The second pipe body extends at least at its lower part and is fitted onto the second end of the inclined section. The inclined section is inclined from top to bottom toward the transverse section. A water collection tank with an open top is provided at the connection between the transverse section and the inclined section. The water collection tank is connected to the first pipe body, and the bottom of the second pipe body abuts against the side wall of the water collection tank.
[0007] In order to better position the water collection trough for the second pipe, the side wall of the water collection trough that connects with the inclined section extends vertically and abuts against the bottom of the second pipe.
[0008] To reduce the probability of airflow blowing up condensate, the bottom wall of the transverse section and the bottom wall of the inclined section are both at a higher height than the bottom wall of the water collection tank.
[0009] Preferably, the bottom wall of the water collection tank is a stepped surface that gradually descends from the transverse section to the inclined section. Because the airflow may generate turbulence at the bend and impact the condensate, the lower the bottom wall of the water collection tank is along the airflow path, the less water will be impacted by the airflow. At the same time, this structural form of the water collection tank can also store more condensate.
[0010] To reduce the probability of airflow stirring up condensate, the connection point between the transverse and inclined sections directly above the water collection tank is arc-shaped. This allows for smooth airflow at the bend, reducing turbulence and the likelihood of condensate being stirred up, thus minimizing noise generation.
[0011] In order to achieve communication between the horizontal section and the washing chamber of the dishwasher, the first tube also includes a vertically extending vertical section, the upper end of which is connected to the second end of the horizontal section, and the lower end of which is used to communicate with the washing chamber of the dishwasher.
[0012] Preferably, at the connection between the vertical and horizontal sections, the flow area of the vertical section is smaller than that of the horizontal section. This increases the flow area at the bend, reduces the air velocity, and prevents water vapor from accumulating at the bend, thus eliminating the sound of water bubbles being blown around. Furthermore, the increased flow area allows for smoother water vapor flow, resulting in better drying performance.
[0013] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: an integrated cleaning device, characterized in that: it includes a water tank assembly and a dishwasher, the water tank assembly includes a water tank and a water tank cleaning machine arranged side by side, the dishwasher is located below the water tank, a breather connected to its washing chamber is provided on the side wall of the dishwasher, the top of the breather is connected to the exhaust pipe for steam discharge, and an air inlet connected to the exhaust pipe is opened on the side wall of the water tank.
[0014] In the above scheme, the respirator and the air inlet are located on the left and right sides of the central axis of the dishwasher, respectively.
[0015] To reduce condensation, the transverse section is located at the top of the dishwasher and at least partially adheres to the top wall of the dishwasher. This allows heat from the dishwasher's drying process to be transferred to the transverse section, reducing condensation.
[0016] Compared with the prior art, the advantages of this utility model are: by setting up a water collection tank, the condensate formed in the exhaust pipe will flow into the water collection tank and will not surge up and down with the airflow, thus preventing noise. In addition, during the later stage of drying, the evaporation rate of water in the exhaust pipe is greater than the condensation rate, and the amount of condensate in the exhaust pipe will remain at a constant value as the machine continues to run.
[0017] Meanwhile, the inclined extension of the inclined section guides the condensate, facilitating its return to the collection tank. Furthermore, the inclined extension of both the inclined section and the lower part of the second pipe ensures that the bottom of the second pipe abuts against the collection tank, thus limiting the installation position of the second pipe and preventing it from being installed too low, resulting in a loose connection and air leakage. Additionally, the inclined extension of the inclined section, compared to a perpendicular connection with the horizontal section, results in a gentler flow of air and water, preventing the water from surging violently up and down with the airflow and producing a loud blowing sound.

[0026] like Figures 1-5 As shown, the integrated cleaning device of this preferred embodiment includes a water tank assembly and a dishwasher 1 disposed below the water tank assembly. The water tank assembly includes a water tank 2 and a water tank cleaning machine 3 arranged side by side. The dishwasher 1 is located below the water tank 2. A breather 11 is provided on the side wall of the dishwasher 1 and communicates with its washing chamber. The top of the breather 11 is connected to an exhaust pipe A for steam discharge. An air inlet is opened on the side wall of the water tank 2 and communicates with the exhaust pipe A. The breather 11 and the air inlet are located on the left and right sides of the central axis of the dishwasher 1, respectively. The central axis refers to the line that passes vertically through the center of the dishwasher 1.
[0027] The above are all existing technologies, and will not be elaborated further here. This embodiment mainly improves the structure of exhaust pipe A.
[0028] like Figure 3 , 4As shown in Figure 5, the exhaust pipe A includes a first pipe body 4 and a second pipe body 5. The first pipe body 4 includes a horizontal section 41, a vertical section 42, and an inclined section 43. The vertical section 42 extends vertically, the horizontal section 41 extends horizontally, and the inclined section 43 is inclined from top to bottom toward the horizontal section 41. The upper end of the vertical section 42 is connected to the second end of the horizontal section 41, and the lower end of the vertical section 42 is connected to the breather 11, thereby achieving communication with the washing chamber of the dishwasher 1. The first end of the horizontal section 41 is connected to the first end of the inclined section 43. The second pipe body 5 extends at least at the lower part and is fitted onto the second end of the inclined section 43.
[0029] As can be seen from the above, bends are formed at the connection point b between the vertical segment 42 and the horizontal segment 41, and at the connection point a between the horizontal segment 41 and the inclined segment 43. Condensation water easily accumulates at the bends, and when the airflow passes through, it will generate noise from the water blowing air. This embodiment addresses this problem by adopting the following method.
[0030] At the connection point a between the transverse section 41 and the inclined section 43, there is a water collection tank 44 with an open top. The water collection tank 44 is connected to the first pipe body 4. In this way, the condensate formed in the exhaust pipe A will flow into the water collection tank 44 and will not surge up and down with the airflow to produce noise. In addition, in the later stage of drying, the evaporation rate of water in the exhaust pipe A is greater than the condensation rate. The amount of condensate in the exhaust pipe A will remain at a constant value as the machine runs continuously.
[0031] In addition, in order to reduce the probability of airflow blowing condensate, the bottom wall of the transverse section 41 and the bottom wall of the inclined section 43 are at a higher height than the bottom wall of the water collection tank 44.
[0032] In this embodiment, the bottom wall of the water collection tank 44 is a stepped surface 441 that gradually descends from the transverse section 41 to the inclined section 43. Because the airflow may generate turbulence that impacts the condensate at the bend, the bottom wall of the water collection tank 44 is lower as the airflow path changes, which reduces the amount of water impacted by the airflow. At the same time, this structural form of the water collection tank 44 can also store more condensate.
[0033] Furthermore, to reduce the probability of airflow stirring up condensate, the connection point between the transverse section 41 and the inclined section 43, located directly above the water collection tank 44, has an arc-shaped structure 45. This allows the airflow to flow smoothly at the bend, reducing turbulence and the probability of impacting condensate, thereby reducing noise generation.
[0034] The bottom of the second pipe 5 abuts against the side wall of the water collection tank 44. In this embodiment, the side wall of the water collection tank 44 that connects with the inclined section 43 extends vertically, and the side wall c abuts against the bottom of the second pipe 5, so that the water collection tank 44 can better position the second pipe 5 and prevent the second pipe 5 from being installed too low and not tightly connected to the water tank 1, causing air leakage.
[0035] The inclined section 43 extends at an angle, which guides the condensate water, making it easier for it to flow back into the collection tank 44. At the same time, the inclined section 43 extends at an angle, which, compared to the scheme where it is connected perpendicularly to the transverse section 41, makes the flow of air and water more gentle, and the water will not produce a loud blowing sound due to the violent up and down movement of the airflow.
[0036] In addition, because the inclined section 43 extends at an angle, the lower part of the second pipe body 5 also extends at an angle, which facilitates positioning by abutting against the water collection tank 44.
[0037] Preferably, at the connection point b between the vertical section 42 and the horizontal section 41, the flow area of the vertical section 42 is smaller than that of the horizontal section 41. This increases the flow area at the bend, reduces the air velocity, and prevents water vapor from accumulating at the bend, thus eliminating the sound of water bubbles. Furthermore, the increased flow area allows for smoother water vapor flow, resulting in better drying performance.
[0038] The transverse section 41 is located at the top of the dishwasher 1 and is at least partially attached to the top wall of the dishwasher 1, so that the heat from the dishwasher 1 during drying is transferred to the transverse section 41, reducing the generation of condensate.
[0039] The lower end of the transverse section 41 can be inserted into or fitted onto the respirator 11 to connect the two. Preferably, the transverse section 41 is inserted into the respirator 11 and a sealing ring is provided between the two. The lower end of the transverse section 41 can be made of hard or soft material.
