[0028] refer to Figure 1-2, the present application provides a dishwasher, comprising:
[0029] The inner tank is enclosed to form a dishwasher cavity 1, and a first drain port is arranged on the inner tank. In specific implementation, according to the conventional placement of the dishwasher, the first drain port is usually arranged on the side of the inner tank near the bottom of the dishwasher to ensure that the water in the dishwasher cavity 1 can be drained smoothly.
[0030] The first drainage pipeline 2 is provided with a drainage pump 3; the first drainage pipeline 2 is connected to the first drainage port outside the dishwasher cavity 1, so that the first drainage pipeline 2 is connected to the dishwasher cavity 1. Specifically, the drainage pump 3 drives the impeller to rotate at a high speed through the motor to extract the waste water from the dishwasher cavity 1 and discharge it through the first drainage pipeline 2.
[0031] The drainage device includes a second drainage pipeline 4 and a plurality of drainage valves 5 arranged in the second drainage pipeline 4; the second drainage pipeline 4 is connected to the first drainage pipeline 2; the drainage valve 5 is always in a conducting state in the first abnormal state. Specifically, the plurality of drainage valves 5 are arranged in series, the second drainage pipeline 4 is connected to the first drainage pipeline 2, and the waste water in the first drainage pipeline 2 is discharged from the second drainage pipeline 4 through the plurality of drainage valves 5. In a specific implementation, the interior of the drainage valve 5 is usually composed of a valve body and a valve. In the non-drainage stage, the valve is closed to ensure that the valve can effectively prevent the outflow of water in the dishwasher cavity 1 and prevent backflow; in the drainage stage, the valve is opened, thereby allowing the waste water in the dishwasher cavity 1 to pass through the second drainage pipeline 4.
[0032] If the drain valve 5 is in the first abnormal state, the valve is always open and cannot be closed. During the drainage process, water will flow back, affecting the washing effect. Moreover, during the dishwashing process, water will continuously enter the dishwasher cavity 1, and part of the water flow may flow out through the drain valve 5 and will not be fully utilized, which not only wastes precious water resources, but also increases the family's water bill expenditure.
[0033] Specifically, in the embodiment of the present application, by connecting a plurality of drain valves 5 in series on the second drain pipe, if any one or more of the drain valves 5 are in the first abnormal state, the other drain valves 5 that are not in the first abnormal state can also control the valve closure in the non-drainage stage, thereby maintaining the normal operation of the dishwasher drainage system without the need for maintenance, thereby increasing the service life of the dishwasher and reducing the maintenance rate.
[0034] In a possible implementation, there are two drain valves 5 on the second drain pipe 4. If one drain valve 5 cannot be opened, the entire second drain pipe 4 cannot drain water. The more drain valves 5 there are on the second drain pipe 4, the higher the probability of blockage of the second drain pipe 4. If the drain valve 5 cannot be closed, backflow may occur, or part of the water may flow out through the drain valve 5 during dishwashing, resulting in waste of water resources. The more drain valves 5 there are on the second drain pipe 4, the lower the probability of backflow or waste of water resources. Setting the number of drain valves 5 on the second drain pipe 4 to two reduces the probability of backflow or waste of water resources, and at the same time minimizes the increase in the probability of blockage of the second drain pipe 4 caused by this.
[0035] Specifically, in the embodiment of the present application, two drain valves 5 are arranged in series in the second drain pipe 4. If the valve of one of the drain valves 5 cannot be closed, the other drain valve 5 can also control the valve closure in the non-drainage stage, which can effectively prevent the outflow of water in the dishwasher cavity 1 and prevent backflow, thereby maintaining the normal operation of the dishwasher drainage system. No maintenance is required, the service life of the dishwasher is increased, the maintenance rate is reduced, and the increase in production costs is minimized.
[0036] In a possible implementation, the drain valve 5 is always in a closed state in the second abnormal state; there are multiple drain devices, and the second drain pipe 4 of each drain device is respectively connected to the first drain pipe 2. Specifically, the multiple second drain pipes 4 can be respectively connected to the first drain pipe 2 through a multi-way pipe joint. In a specific implementation, the drain valve 5 is usually composed of a valve body and a valve. In the non-drainage stage, the valve is closed to ensure that the valve can effectively prevent the outflow of water in the dishwasher cavity 1 and prevent backflow; in the drainage stage, the valve is opened to allow the waste water in the dishwasher cavity 1 to pass through the second drain pipe 4.
[0037] If the drain valve 5 is in the second abnormal state, the valve is always closed and cannot be opened, or the second drain pipe 4 is compressed or bent, the waste water in the dishwasher cavity 1 cannot be discharged through the second drain pipe 4 during the drainage process.
[0038] Specifically, in the embodiment of the present application, multiple second drainage pipes 4 are provided to be connected to the first drainage pipe 2 respectively. If the drainage valves 5 on any one or more of the second drainage pipes 4 are in the second abnormal state, the drainage valves 5 on other second drainage pipes 4 can also control the valves to open during the drainage stage, so as to maintain the normal operation of the drainage system of the dishwasher without the need for maintenance, thereby increasing the service life of the dishwasher and reducing the maintenance rate; and by draining water simultaneously through multiple second drainage pipes 4, the drainage efficiency is improved, and the problem of incomplete drainage of the dishwasher is alleviated.
[0039] In a possible implementation, there are two drainage devices. Specifically, each drainage device includes a second drainage pipeline 4 and a plurality of drainage valves 5 disposed on the second drainage pipeline 4, and each second drainage pipeline 4 is respectively connected to the first drainage pipeline 2. Specifically, the two second drainage pipelines 4 can be respectively connected to the first drainage pipeline 2 through a three-way pipe joint.
[0040] Specifically, in the embodiment of the present application, two second drainage pipes 4 are provided to be connected to the first drainage pipe 2 respectively. If one of the second drainage pipes 4 is blocked, the other second drainage pipe 4 can also maintain the normal operation of the dishwasher drainage system without the need for maintenance, thereby increasing the service life of the dishwasher and reducing the maintenance rate; and by draining water simultaneously through the two second drainage pipes 4, the drainage efficiency is improved, and the problem of incomplete drainage of the dishwasher is alleviated; and the increase in production costs is reduced as much as possible.
[0041] In a possible implementation, the number of drain valves 5 corresponding to the second drain pipeline 4 of one of the two drain devices is greater than the number of drain valves 5 corresponding to the second drain pipeline 4 of the other drain device. Exemplarily, the number of drain valves 5 corresponding to one second drain pipeline 4 is 3, and the number of drain valves 5 corresponding to the other second drain pipeline 4 is 2.
[0042] By setting two second drainage pipes 4 connected to the first drainage pipe 2 respectively, drainage is simultaneously conducted through the plurality of second drainage pipes 4. If any one or more of the second drainage pipes 4 are blocked, the other second drainage pipes 4 can still maintain the normal operation of the drainage system of the dishwasher without the need for maintenance. Multiple drainage valves 5 are set on each second drainage pipe 4. If any one or more of the drainage valves 5 cannot be closed, the other drainage valves 5 can also control the valve closure in the non-drainage stage, which can effectively prevent the outflow of water in the dishwasher cavity 1 and prevent backflow, thereby maintaining the normal operation of the drainage system of the dishwasher without the need for maintenance. The maintenance rate is reduced and the service life of the dishwasher is increased.
[0043] If a drain valve 5 cannot be opened, the entire second drain pipe 4 cannot drain water. The more drain valves 5 there are on the second drain pipe 4, the higher the probability of blockage of the second drain pipe 4. If the drain valve 5 cannot be closed, backflow may occur, or part of the water may flow out through the drain valve 5 during the dishwashing process, resulting in a waste of water resources. The more drain valves 5 there are on the second drain pipe 4, the lower the probability of backflow or waste of water resources.
[0044] Specifically, in the embodiment of the present application, by setting two second drainage pipes 4 respectively connected to the first drainage pipe 2, the drainage efficiency is improved and the problem of incomplete drainage of the dishwasher is alleviated; the number of drain valves 5 corresponding to one of the second drainage pipes 4 is greater than the number of drain valves 5 corresponding to the other second drainage pipe 4. The former number is set to reduce the probability of backflow or waste of water resources, and the latter number is set to minimize the increase in the probability of blockage of the second drainage pipe 4 caused by this.
[0045] In a possible implementation, the number of drain valves 5 corresponding to the second drain pipeline 4 of one of the two drain devices is one. Specifically, the number of drain valves 5 corresponding to one second drain pipeline 4 is multiple, and the number of drain valves 5 corresponding to the other second drain pipeline 4 is one.
[0046] If a drain valve 5 cannot be opened, the entire second drain pipe 4 cannot drain water. The more drain valves 5 there are on the second drain pipe 4, the higher the probability of blockage of the second drain pipe 4. If the drain valve 5 cannot be closed, backflow may occur, or part of the water may flow out through the drain valve 5 during the dishwashing process, resulting in a waste of water resources. The more drain valves 5 there are on the second drain pipe 4, the lower the probability of backflow or waste of water resources.
[0047] Specifically, in the embodiment of the present application, two second drainage pipes 4 are provided to be connected to the first drainage pipe 2 respectively, so that the drainage efficiency is improved and the problem of incomplete drainage of the dishwasher is alleviated; the number of drainage valves 5 corresponding to one of the second drainage pipes 4 is multiple, which reduces the probability of backflow or waste of water resources, and the number of drainage valves 5 corresponding to the other second drainage pipe 4 is 1, which minimizes the increase in the probability of blockage of the second drainage pipe 4.
[0048] In one possible embodiment, each second drainage pipe 4 is connected to the first drainage pipe 2 through a pipe joint; the pipe joint includes a first interface and multiple second interfaces, the first interface is respectively connected to each second interface, and the multiple second interfaces correspond one-to-one to multiple drainage devices; the first drainage pipe 2 is connected to the pipe joint through the first interface, and the second drainage pipe 4 of each drainage device is respectively connected to the pipe joint through the corresponding second interface.
[0049] Specifically, in the embodiment of the present application, each second drainage pipe 4 is connected to the first drainage pipe 2 through a pipe joint; the pipe joint includes a first interface and multiple second interfaces, the number of the second interfaces is consistent with the second drainage pipe 4, the first drainage pipe 2 is connected to the pipe joint through the first interface, and each second drainage pipe 4 is connected to the pipe joint through the corresponding second interface to achieve drainage of multiple drainage pipes, thereby improving the drainage efficiency and alleviating the problem of incomplete drainage of the dishwasher; further, if any one or more of the second drainage pipes 4 are blocked, the other second drainage pipes 4 can also maintain the normal operation of the dishwasher drainage system without the need for maintenance, thereby increasing the service life of the dishwasher and reducing the maintenance rate.
[0050] In a possible embodiment, the dishwasher further includes a shell, the shell encloses a storage space, the inner tank is arranged in the storage space, and a remaining storage space 6 is formed between the inner tank and the shell; the first drainage pipeline 2 is arranged in the remaining storage space 6. Specifically, according to the conventional prevention of the dishwasher, the inner tank is arranged near the top of the dishwasher, the remaining storage space 6 is near the bottom of the dishwasher, and the first drainage pipeline 2 and the drainage pump 3 arranged in the first drainage pipeline 2 are both arranged in the remaining storage space 6.
[0051] The shell is provided with a second drain port, and the second drain pipe 4 passes through the second drain port in the remaining accommodation space 6 and extends to the outside of the accommodation space; a plurality of drain valves 5 are provided in the remaining accommodation space 6. Specifically, the second drain pipe 4 extends to the outside of the accommodation space formed by the shell and leads to the sewer.
[0052] Specifically, in the embodiment of the present application, the first drainage pipe 2 is arranged between the inner tank and the shell to form a remaining storage space 6, and the second drainage pipe 4 is connected to the first drainage pipe 2 in the remaining storage space 6, and extends to the outside of the storage space formed by the shell, thereby reducing the pipes arranged outside the dishwasher and facilitating the user to arrange the pipes.
[0053] In a possible implementation manner, the number of the second drain ports matches the number of the second drain pipes 4 .
[0054] Specifically, in the embodiment of the present application, a second drain port corresponding to each second drain pipe is provided on the washing machine shell, and each second drain pipe 4 extends through the corresponding second drain port to the outside of the accommodating space formed by the shell, thereby avoiding squeezing of multiple second drain pipes 4 against each other, thereby causing blockage of the second drain pipe 4 and reducing the maintenance rate.
[0055] In a possible implementation manner, the size of the second drain port matches the number of the second drain pipes 4 .
[0056] Specifically, in the embodiment of the present application, a plurality of second drain outlets corresponding to the second drain pipes are arranged on the washing machine shell, and the size of the second drain outlet matches the total size of the plurality of second drain pipes. The plurality of second drain pipes 4 extend through the second drain outlets to the outside of the accommodating space formed by the shell, thereby avoiding squeezing of the plurality of second drain pipes 4 against each other, which in turn causes blockage of the second drain pipes 4 and reduces the maintenance rate.
