Description

Technical Field

[0001] This utility model relates to the field of cleaning machines, and in particular to an integrated cleaning machine. Background Technology

[0002] Most dishwashers on the market currently come with a built-in drying function, which dries the dishes and the inside of the washing tub after the washing process. For example, Chinese utility model patent number ZL202321646603.X (CN220512820U) discloses a drying mechanism for a dishwasher, including a heating element disposed in the inner tub. The inner tub has an air inlet connected to an air supply assembly. Outside air enters the inner tub through the air inlet under the action of the air supply assembly, is heated by the heating element, and then circulates as hot air within the inner tub under the action of the air supply assembly.

[0003] Furthermore, as dishwashers become increasingly common in kitchens, their configurations are also becoming more diverse. For example, the applicant's earlier application ZL202322663317.0 (authorization announcement number CN 221383467U) discloses an integrated washing machine device, including a first sink and a second sink arranged side by side in a cabinet. A first washing tub is disposed below the first sink, and the second sink can be switched to become a second washing tub. The first washing tub is a front-opening dishwasher, and the second sink constitutes a top-opening dishwasher. An overflow seat is disposed between the first and second sinks. The overflow seat is provided with a second air inlet connected to a first air outlet of the first washing tub, a first air inlet connected to a second air outlet of the second sink, and an air outlet connected to the first sink.

[0004] Furthermore, dishwashers can be combined with garbage disposers, water purifiers, and fruit and vegetable machines to create integrated cleaning machines. However, most current integrated cleaning machines are merely simple combinations of various modules, failing to achieve true integration in functionality. For example, current integrated cleaning machines that incorporate multiple dishwashers each have an independent drying structure, making the internal structure complex and cumbersome, difficult to operate, and increasing production costs. Summary of the Invention

[0005] The first technical problem to be solved by this utility model is to provide an integrated cleaning machine with a shared drying structure, which is in contrast to the prior art.

[0006] The second technical problem to be solved by this utility model is to provide an integrated cleaning machine with a shared drying structure and convenient operation, which is in contrast to the prior art.

[0007] The third technical problem to be solved by this utility model is to provide an integrated cleaning machine with a shared drying structure and high drying efficiency, which is in contrast to the prior art.

[0008] The technical solution adopted by this utility model to solve at least one of the above-mentioned technical problems is as follows: an integrated cleaning machine, comprising a first washing inner tank and a second washing inner tank, wherein the first washing inner tank has a first air inlet and the second washing inner tank has a second air inlet, and further comprising a drying structure, characterized in that the drying structure comprises a drying channel, a drying fan and a heater, wherein the drying channel comprises a first air duct, a second air duct and a third air duct, wherein the drying fan and the heater are respectively disposed in the first air duct, and the air introduced into the first air duct by the drying fan is heated by the heater and blown out from the first outlet of the first air duct.

[0009] The second inlet of the second air duct is in fluid communication with the first outlet, while the second outlet of the second air duct is in fluid communication with the first air inlet.

[0010] The third inlet of the third air duct can also be fluidly connected with the first outlet, while the third outlet of the third air duct is fluidly connected with the second air inlet.

[0011] It also includes a control element for controlling the fluid communication between the first outlet and the second and / or third inlet.

[0012] Furthermore, the drying channel also includes a control air duct with a first air inlet, a second air inlet, and a third air inlet, wherein the first air inlet is always in fluid communication with the first outlet, and the control component is installed in the control air duct and used to control the opening and closing of the second and / or third air inlets. By setting up the control air duct and placing the control component in the control air duct, the fluid communication between the first outlet and the second and / or third inlet can be better controlled. And it has at least the following three states:

[0013] In the first state, the control unit controls the second air vent to close and the third air vent to open, and the third air vent is in phase communication with the third inlet. Then the second air duct is closed and the third air duct is open, and the hot air blown out of the first air duct enters the third air duct and is introduced into the second washing tank through the third air duct.

[0014] In the second state, the aforementioned control unit controls the third air vent to close and the second air vent to open, and the second air vent is in phase communication with the aforementioned second inlet; then the third air duct is closed and the second air duct is open, and the hot air blown out of the first air duct enters the second air duct and is introduced into the first washing inner tank through the second air duct.

[0015] In the third state, the aforementioned control unit controls the second and third air vents to open simultaneously, with the second air vent in fluid communication with the second inlet and the third air vent in fluid communication with the third inlet. In this way, the second and third air ducts open simultaneously, and the hot air blown out from the first air duct enters the second and third air ducts respectively, and is then directed into the corresponding washing tanks.

[0016] Furthermore, the control component is a swing-mounted plate. In the initial state, the control component is stationary at its swing center line. In the first state, the control component swings to the second air vent and blocks the second air vent, thus closing it.

[0017] In the second state described above, the control component swings to the third air vent and blocks the third air vent, thus closing it off.

[0018] In the third state described above, the control component is positioned horizontally between the second and third air vents, separating the first air vent. One portion of the separated first air vent is connected to the second air vent, while the other portion is connected to the third air vent. This simplifies the structure of the control component, and the swinging motion of the control component effectively controls the opening and closing of the second and / or third air vents.

[0019] Furthermore, in the first and second states, the control component is at its maximum swing angle, while in the third state, it is at its swing centerline. This allows the control component to be more stable in the required position under various states, thereby enabling better control over the opening and closing of the second and / or third air vents.

[0020] Furthermore, the swing center line of the control component is perpendicular to the setting direction of the first air vent. In the initial state, the control component is opposite to the first air vent, while the second and third air vents are located on both sides of the control component.

[0021] In the first state, the first washing inner tank is in the cleaning state while the second washing inner tank is not in the working state. The air pressure at the second air vent is greater than that at the third air vent. The control component rotates towards the third air vent to a first angle with its initial state. The drying fan operates, and the air pressure at the first air vent causes the control component to continue rotating from the first angle towards the third air vent until the third air vent is closed. When the first washing inner tank is in the cleaning state, a large amount of steam is generated inside the first washing inner tank during the cleaning process, which increases its internal air pressure. Since the second air vent and the first washing inner tank are fluidly connected through the first air inlet, the air pressure at the second air vent increases. Under the action of the pressure difference on both sides, the control component rotates to the first angle. At this time, driven by the drying fan, hot air enters the control air duct from the first air vent and acts on the control component. The control component continues to rotate and closes the third air vent.

[0022] In the second state, the second washing inner tank is in the cleaning state while the first washing inner tank is not in operation. The air pressure at the third air vent causes the control component to rotate towards the second air vent to a second angle relative to its initial state. The drying fan operates, and the air pressure at the first air vent causes the control component to continue rotating from the second angle towards the second air vent until the second air vent is closed. When the second washing inner tank is in the cleaning state, a large amount of steam is generated inside the second washing inner tank during the cleaning process, increasing its internal air pressure. Since the third air vent and the second washing inner tank are fluidly connected through the second air inlet, the air pressure at the third air vent increases. Under the action of the pressure difference on both sides, the control component rotates to the second angle. At this time, driven by the drying fan, hot air enters the control duct from the first air vent and acts on the control component. The control component continues to rotate and closes the second air vent.

[0023] In the third state, both the first and second washing tanks are simultaneously in the washing state. The air pressure at the second and third air vents acts simultaneously on the control component, which is positioned between the second and third air vents. The air pressure inside the first washing tank and the air pressure inside the second washing tank also act simultaneously on the control component. The control component is balanced on both sides, placing it at its own swing centerline, and the second and third air vents open simultaneously. Therefore, in both the first and second states, the control component can be triggered to rotate by the internal air pressure change of the corresponding washing tank during the washing state. Then, the airflow from the first air duct closes the corresponding air vent (the second or third air vent), thus achieving control over the opening and closing of the second and / or third air vents.

[0024] Furthermore, the swing center line of the control component extends vertically, so the first air outlet is arranged horizontally, while the second and third air outlets are arranged vertically and located on either side of the first air outlet. This allows the control component to rotate more effectively under the pressure difference acting on it, thereby better controlling the opening and closing of the second and / or third air outlets. Moreover, the first and second angles are both between 5° and 10°, allowing the airflow from the first duct to better act on the control component, enabling it to rotate effectively and close the second or third air outlet. The maximum swing angle of the control component is 45°, which helps it stabilize in the closed state of the second or third air outlet, ensuring the reliability of the closed state.

[0025] Furthermore, the control component is a long, straight plate, with its first end rotatably connected to the aforementioned control duct, while its second end can rotate back and forth around the first end. This simplifies the structure of the control component and enables stable installation and effective oscillation of the control component within the control duct.

[0026] The side wall of the control duct at the junction of the second air outlet and the first air outlet bends to form a first limiting part. In the first state, the second end of the control member abuts against the first limiting part and is positioned in the state of closing the second air outlet, thereby enabling the control member to be more stable in the state of closing the second air outlet and ensuring the reliability of the control member's action to close the second air outlet.

[0027] The side wall of the control duct at the junction of the third air outlet and the first air outlet bends to form a second limiting part. In the second state, the second end of the control member abuts against the second limiting part and is positioned in the state of closing the third air outlet, thereby enabling the control member to be more stable in the state of closing the third air outlet and ensuring the reliability of the control member's action to close the third air outlet.

[0028] Furthermore, the drying fan is installed at the first inlet of the first air duct, and the heater is block-shaped and spaced within the first air duct, with a ventilation gap formed between the outer surface of the heater and the side wall of the first air duct to allow airflow. In this way, the air drawn into the first air duct by the drying fan can be fully heated within the first air duct, and the heated air can smoothly pass through the ventilation gap and be discharged from the first outlet of the first air duct.

[0029] Furthermore, at least one surface of the heater is provided with protrusions, and each protrusion is spaced apart from the surface of the heater to create the aforementioned ventilation gap. This not only creates the ventilation gap but also further improves the heater's heating efficiency of the air.

[0030] Furthermore, the first and second washing inner tanks are arranged side by side. The drying structure also includes a fan hood, in which the drying channel is located. One end of the fan hood is located on the outer surface of the first washing inner tank, connecting the second outlet to the first air inlet. The other end of the fan hood is located on the outer surface of the second washing inner tank, connecting the third outlet to the second air inlet. This facilitates the installation of the drying channel in the integrated washing machine and allows the drying channel to more efficiently input hot air into the corresponding washing inner tank, thereby improving drying efficiency.

[0031] Compared with existing technologies, the advantages of this invention are as follows: the drying structure includes a first air duct, a second air duct, and a third air duct. The second air duct guides the hot air blown from the first air duct into the first washing drum, thus drying the interior of the first washing drum. The third air duct guides the hot air blown from the first air duct into the second washing drum, thus drying the interior of the second washing drum. Therefore, this invention solves the drying problems of both the first and second washing drums simultaneously using a single drying structure, eliminating the need for separate drying channels for the first and second washing drums. This simplifies the internal structure of the integrated cleaning machine, improves integration, and effectively reduces production costs. Furthermore, by setting a control component to control the fluid connection between the first outlet and the second and / or third inlet, the on / off control of the second and third air ducts is achieved. This allows for the coordinated control of the drying function of both the first and second washing drums, making operation convenient and further enhancing the integration of the device.

[0040] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0041] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0042] like Figures 1-8 As shown, an integrated cleaning machine includes a first washing tank 21 and a second washing tank 31, wherein the first washing tank 21 has a first air inlet 211, and the second washing tank 31 has a second air inlet 311.

[0043] Furthermore, it also includes a drying structure 4, which includes a drying channel 40, a drying fan 42, and a heater 43. The drying channel 40 includes a first air duct 401, a second air duct 402, and a third air duct 403. The drying fan 42 and the heater 43 are respectively located in the first air duct 401. Air introduced into the first air duct 401 by the drying fan 42 is heated by the heater 43 and then blown out from the first outlet 4011 of the first air duct 401. The second inlet 4021 of the second air duct 402 is in fluid communication with the first outlet 4011, and the second outlet 4022 of the second air duct 402 is in fluid communication with the first air inlet 211. The third inlet 4031 of the third air duct 403 is also in fluid communication with the first outlet 4011, and the third outlet 4032 of the third air duct 403 is in fluid communication with the second air inlet 311. Furthermore, the aforementioned drying channel 40 also includes a control element 5 for controlling the fluid communication between the aforementioned first outlet 4011 and the aforementioned second inlet 4021 and / or third inlet 4031.

[0044] As can be seen from the above, the drying channel 40 of this utility model includes a first air duct 401, a second air duct 402, and a third air duct 403. The second air duct 402 guides the hot air blown out of the first air duct 401 into the first washing inner tank 21, thereby drying the interior of the first washing inner tank 21. The third air duct 403 guides the hot air blown out of the first air duct 401 into the second washing inner tank 31, thereby drying the interior of the second washing inner tank 31. Therefore, this utility model, by setting up a single drying channel 40, can simultaneously solve the drying problems of the first washing inner tank 21 and the second washing inner tank 31, eliminating the need for separate drying channels for the first and second washing inner tanks 31. This simplifies the internal structure of the integrated cleaning machine, improves integration, and effectively reduces production costs. Furthermore, by setting control element 5 to control the fluid communication between the first outlet 4011 and the second inlet 4021 and / or the third inlet 4031, the on / off control of the second air duct 402 and the third air duct 403 can be realized, thereby enabling the on / off control of the drying function of the first washing inner tank 21 and the second washing inner tank 31, further improving the integration of the device.

[0045] In this embodiment, specifically, the integrated cleaning machine also includes a cabinet 1, in which a first water tank 22 and a second water tank are arranged side by side. The first washing inner tank 21 is provided below the first water tank 22, and the second water tank can be switched to the second washing inner tank 31. The first washing inner tank 21 is a front-opening first dishwasher 2, and the second water tank constitutes a top-opening second dishwasher 3.

[0046] Furthermore, the aforementioned drying channel 40 also includes a control air duct 404 having a first air outlet 4041, a second air outlet 4042, and a third air outlet 4043. The first air outlet 4041 is always in fluid communication with the first outlet 4011. The control element 5 is installed in the control air duct 404 and is used to control the opening and closing of the second air outlet 4042 and / or the third air outlet 4043. In this invention, by setting up the control air duct 404 and placing the control element 5 within it, the fluid communication between the first outlet 4011 and the second inlet 4021 and / or the third inlet 4031 can be better controlled. It also has at least the following three states:

[0047] In the first state, the control element 5 controls the second air outlet 4042 to close and the third air outlet 4043 to open and be in fluid communication with the third inlet 4031; then the second air duct 402 is closed and the third air duct 403 is open, the hot air blown out of the first air duct 401 enters the third air duct 403 and is introduced into the second washing inner tank 31 through the third air duct 403.

[0048] In the second state, the control element 5 controls the third air outlet 4043 to close, and the second air outlet 4042 to open and be in fluid communication with the second inlet 4021; then the third air duct 403 is closed and the second air duct 402 is open, and the hot air blown out of the first air duct 401 enters the second air duct 402 and is introduced into the first washing inner tank 21 through the second air duct 402.

[0049] In the third state, the aforementioned control component 5 controls the second air vent 4042 and the third air vent 4043 to open simultaneously, with the second air vent 4042 in fluid communication with the aforementioned second inlet 4021, and the third air vent 4043 in fluid communication with the aforementioned third inlet 4031 (e.g., Figure 5 and Figure 6 (As shown). In this way, the second air duct 402 and the third air duct 403 are opened at the same time, and the hot air blown out by the first air duct 401 enters the second air duct 402 and the third air duct 403 respectively, and is then introduced into the corresponding washing tank.

[0050] Furthermore, in this embodiment, the control element 5 is a swing-mounted plate. Initially, the control element 5 is stationary at its swing center line 51, as shown below. Figure 6 As shown. Furthermore, in the first state, the control member 5 swings to the second air vent 4042 and blocks it, thus closing it. In the second state, the control member 5 swings to the third air vent 4043 and blocks it, thus closing it. In the third state, the control member 5 is positioned horizontally between the second air vent 4042 and the third air vent 4043, separating the first air vent 4041. A portion of the separated first air vent 4041 is connected to the second air vent 4042, while the other portion is connected to the third air vent 4043, as shown. Figure 5 and Figure 6 As shown. The above settings simplify the structure of the control element 5, and the swing of the control element 5 can effectively control the opening and closing of the second air vent 4042 and / or the third air vent 4043.

[0051] Preferably, in the first and second states, the control element 5 is at its maximum swing angle, while in the third state, the control element 5 is at its swing center line 51. This allows the control element 5 to be more stable in the required position in various states, thereby enabling better control over the opening and closing of the second air vent 4042 and / or the third air vent 4043.

[0052] Furthermore, such as Figure 5 and Figure 6As shown, the swing center line 51 of the control component 5 is perpendicular to the setting direction of the first air vent 4041. In the initial state, the control component 5 is opposite to the first air vent 4041, while the second air vent 4042 and the third air vent 4043 are located on both sides of the control component 5.

[0053] Furthermore, in the first state described above, the first washing inner tank 21 is in a washing state while the second washing inner tank 31 is in a non-working state. The air pressure at the second air vent 4042 is greater than that at the third air vent 4043. The control component 5 rotates towards the third air vent 4043 to a position forming a first angle with its initial state. The drying fan 42 operates, and the air pressure at the first air vent 4041 causes the control component 5 to continue rotating from the first angle towards the third air vent 4043 until the third air vent 4043 is closed. When the first washing inner tank 21 is in the cleaning state, a large amount of steam will be generated inside the first washing inner tank 21 during the cleaning process, which will increase the internal air pressure. Since the second air vent 4042 is fluidly connected to the first washing inner tank through the first air inlet 211, the air pressure at the second air vent 4042 will increase. Under the action of the pressure difference on both sides, the control component 5 will rotate to the first angle mentioned above. At this time, driven by the drying fan 42, hot air will enter the control air duct 404 from the first air vent 4041 and act on the control component 5. The control component 5 will continue to rotate and close the third air vent 4043.

[0054] Furthermore, in the second state described above, the second washing inner tank 31 is in a cleaning state while the first washing inner tank 21 is in a non-operating state. The air pressure at the third air vent 4043 causes the control component 5 to rotate towards the second air vent 4042 to a second angle from its initial state. The drying fan 42 operates, and the air pressure at the first air vent 4041 causes the control component 5 to continue rotating from the second angle towards the second air vent 4042 until the second air vent 4042 is closed. When the second washing inner tank 31 is in the cleaning state, a large amount of steam will be generated inside the second washing inner tank 31 during the cleaning process, which will increase the internal air pressure. Since the third air vent 4043 is fluidly connected to the second washing inner tank through the second air inlet 311, the air pressure at the third air vent 4043 will increase. Under the action of the pressure difference on both sides, the control component 5 will rotate to the second angle mentioned above. At this time, driven by the drying fan 42, hot air will enter the control air duct 404 from the first air vent 4041 and act on the control component 5. The control component 5 will continue to rotate and close the second air vent 4042.

[0055] Furthermore, in the third state described above, the first washing inner tank 21 and the second washing inner tank 31 are simultaneously in a washing state. The air pressure at the second air vent 4042 and the air pressure at the third air vent 4043 act simultaneously on the control component 5, causing it to be positioned between the second air vent 4042 and the third air vent 4043. The air pressure inside the first washing inner tank 21 and the air pressure in the second washing inner tank act simultaneously on the control component 5. The control component 5 is balanced by forces on both sides, causing it to be positioned at its own swing centerline 51. The second air vent 4042 and the third air vent 4043 open simultaneously.

[0056] As can be seen, in the first and second states mentioned above, the control component 5 can be triggered to rotate by the change in internal air pressure of the corresponding washing inner tank during the washing state. Then, the corresponding air vent (second air vent 4042 or third air vent 4043) is closed by the air outlet of the first air duct 401, thereby realizing the control of the opening and closing of the second air vent 4042 and / or the third air vent 4043.

[0057] Preferably, the swing center line 51 of the control element 5 extends vertically, so the first air outlet 4041 is arranged horizontally, while the second air outlet 4042 and the third air outlet 4043 are respectively arranged vertically and located on both sides of the first air outlet 4041. This allows the control element 5 to rotate better under the pressure difference acting on it, thereby better controlling the opening and closing of the second air outlet 4042 and / or the third air outlet 4043. Furthermore, the magnitudes of the first angle and the second angle are both 5° to 10°, allowing the air outlet from the first air duct 401 to better act on the control element 5, enabling the control element 5 to effectively rotate and close the second air outlet 4042 or the third air outlet 4043. The maximum swing angle of the control element 5 is 45°, which helps the control element 5 to stabilize in the closed state of the second air outlet 4042 or the third air outlet 4043, ensuring the reliability of the closed state of the second air outlet 4042 or the third air outlet 4043.

[0058] Furthermore, the aforementioned control component 5 is a long, straight plate, with its upper end rotatably connected to the control air duct 404, while its lower end can rotate back and forth around the upper end. This simplifies the structure of the control component 5 and allows for stable installation and effective oscillation of the control component 5 within the control air duct 404. Specifically, the upper end of the control component 5 is provided with a bushing 52, and a rotating shaft 45 is provided in the control air duct 404. The bushing 52 is fitted onto the rotating shaft 45 to achieve the rotational setting of the control component 5. Figure 6 As shown.

[0059] Furthermore, such as Figure 6As shown, the side wall of the control duct 404 at the junction of the second air vent 4042 and the first air vent 4041 bends to form a first limiting part 411. In the first state, the second end of the control member 5 abuts against the first limiting part 411 and is positioned to close the second air vent 4042, thereby enabling the control member 5 to be more stable in the closed state and ensuring the reliability of the control member 5's action to close the second air vent 4042. Similarly, the side wall of the control duct 404 at the junction of the third air vent 4043 and the first air vent 4041 bends to form a second limiting part 412. In the second state, the second end of the control member 5 abuts against the second limiting part 412 and is positioned to close the third air vent 4043, thereby enabling the control member 5 to be more stable in the closed state and ensuring the reliability of the control member 5's action to close the third air vent 4043.

[0060] Furthermore, the aforementioned drying fan 42 is installed on the first inlet 4012 of the first air duct 401. The aforementioned heater 43 is block-shaped and spaced within the first air duct 401, and a ventilation gap 44 for airflow is formed between the outer surface of the heater 43 and the side wall of the first air duct 401. In this way, the air drawn into the first air duct 401 by the drying fan 42 can be fully heated within the first air duct 401, and the heated air can smoothly pass through the ventilation gap 44 and exit the first air duct 401 through the first outlet 4011. Specifically, at least one side surface of the aforementioned heater 43 is provided with protrusions 431, and each protrusion 431 is spaced between the surface of the heater and the side wall of the first air duct 401 to create the aforementioned ventilation gap, such as... Figures 6-8 As shown. This not only creates a ventilation gap, but also further improves the heating efficiency of the heater 43 on the air.
