Description

Technical Field

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

[0002] A dishwasher, also known as a dishwashing machine or a dish and bowl washing machine, is a household appliance used for automatically cleaning tableware, dishes, and bowls. The working principle of the dishwasher is to place the tableware in the inner cavity of the dishwasher, and then remove the food residues and dirt on the tableware through water and detergent. The dishwasher can reduce the burden of washing dishes in daily household life and improve the washing efficiency and hygiene level.

[0003] At the present stage, during the washing process of the dishwasher, water, detergent, and food residues will be mixed together to form waste liquid. When the washing program of the dishwasher ends, the waste liquid can be discharged to the outside of the dishwasher through the drainage system.

[0004] However, after the dishwasher discharges the waste liquid, there is usually still a small amount of waste liquid adhering to the inner wall of the inner cavity, resulting in a relatively high air humidity in the inner cavity. This will cause bacteria to be easily bred in the inner cavity, thus affecting the user experience. Summary of the Invention

[0005] An embodiment of the present invention provides a dishwasher, which solves the problem of relatively high humidity in the inner cavity of the dishwasher after the washing is completed in the prior art.

[0006] To achieve the above object, the embodiment of the present invention adopts the following technical solutions:

[0007] According to a first aspect of the present application, there is provided a dishwasher, including a machine shell, an inner cavity, a drainage device, and a dehumidifying device. A receiving cavity is formed inside the machine shell; the inner cavity is disposed inside the receiving cavity and connected to the machine shell; the inner cavity forms a cleaning cavity and a first water outlet communicating with the cleaning cavity; the drainage device is connected to the first water outlet for discharging the waste liquid in the inner cavity to the outside of the machine shell; the dehumidifying device is connected to the machine shell; the dehumidifying device includes a driving part and a drainage hose. One end of the drainage hose communicates with the first water outlet, and the other end of the drainage hose is used to communicate with the outside of the machine shell; the driving part is connected to the drainage hose for squeezing the drainage hose along the radial direction of the drainage hose and squeezing the peripheral wall of the drainage hose along the direction of the medium flow in the drainage hose to drive the flow of the medium in the drainage hose.

[0008] For the dishwasher provided by the present application, since the inner cavity is disposed inside the receiving cavity and connected to the machine shell, the machine shell can protect the inner cavity. The inner cavity forms a cleaning cavity and a first water outlet communicating with the cleaning cavity, and the drainage device is connected to the first water outlet. In this way, the tableware can be placed in the cleaning cavity for cleaning. When the cleaning of the tableware is completed, the waste liquid generated during the washing process can enter the drainage device through the first water outlet and be discharged to the outside of the machine shell through the drainage device.

[0009] After the drainage is completed, the driving part of the dehumidifying device squeezes the drainage hose along the radial direction of the drainage hose and squeezes the peripheral wall of the drainage hose along the direction of the medium flow in the drainage hose, which can squeeze the air in the drainage hose, continuously discharge the air in the drainage hose from the other end of the drainage hose to the outside of the housing, so that the air pressure in the drainage hose is lower than the air pressure in the cleaning cavity, and thus the air in the cleaning cavity can be continuously sucked into the drainage hose, and the air sucked into the drainage hose is discharged to the outside of the housing under the action of the driving part. The air in the cleaning cavity can take away the moisture and residual water in the cleaning cavity during the process of being discharged to the outside of the housing, thereby reducing the humidity in the cleaning cavity to prevent bacteria from growing in the inner tank, and further improving the user experience.

[0010] In some embodiments, the drainage device includes a drainage container and a drainage pipe. The drainage container is formed with a drainage cavity, an inlet, a drainage outlet and a second outlet communicating with the drainage cavity; the inlet is communicated with the first outlet; one end of the drainage hose is communicated with the drainage outlet, so that one end of the drainage hose is communicated with the first outlet through the drainage container; one end of the drainage pipe is communicated with the second outlet, and the other end of the drainage pipe is used for communicating with the outside of the housing. In this way, when the dishwasher finishes washing the tableware, the waste liquid in the cleaning cavity can enter the drainage container through the inlet, flow through the second outlet into the drainage pipe, and the waste liquid entering the drainage pipe can be discharged to the outside of the housing through the drainage pipe. During the working process of the dehumidifying device, the air with higher humidity and residual water in the drainage cavity can also be discharged to the outside of the housing, so that while the dehumidifying device dehumidifies the cleaning cavity, it can also dehumidify the drainage cavity, enabling the dehumidifying device to have multiple functions, thereby saving the manufacturing cost of the dishwasher.

[0011] In some embodiments, the dishwasher further includes a water volume detection device and a controller. The water volume detection device is disposed in the drainage cavity and connected to the drainage container for detecting the water volume information in the drainage cavity. The controller is connected to both the dehumidifying device and the water volume detection device, and the controller can obtain the water volume information detected by the water volume detection device. The controller is configured to: after the washing program of the dishwasher ends, control the dehumidifying device to operate; determine whether the water volume information is greater than a preset water volume information; if the water volume information is greater than the preset water volume information, control the dehumidifying device to continue operating. In this way, after the washing program of the dishwasher ends, the controller controls the dehumidifying device to operate, improving the automation degree of the dishwasher, enhancing the convenience of controlling the dehumidifying device, and facilitating the timely activation of the dehumidifying device, so that the dishwasher can drain residual water and moisture more promptly through the dehumidifying device, which is more conducive to avoiding the growth of bacteria in the inner tank. Moreover, through the water volume detection device, the water volume information of the residual water in the drainage cavity can be detected in real time, so that the controller can obtain the water volume information of the residual water in the drainage cavity in real time, facilitating the controller to timely know whether the water volume information of the residual water in the drainage cavity meets the requirements, and thus facilitating the controller to control the operation of the dehumidifying device according to the water volume information for more refined control of the dehumidifying device.

[0012] In some embodiments, the dishwasher further includes a humidity detection device. The humidity detection device is disposed in the cleaning cavity and connected to the inner tank for detecting the humidity information in the cleaning cavity. The controller is also connected to the humidity detection device for obtaining the humidity information detected by the humidity detection device. The controller is further configured to: determine whether the humidity information is greater than a preset humidity information; if the humidity information is greater than the preset humidity information, control the dehumidifying device to continue operating; if the humidity information is less than or equal to the preset humidity information, control the dehumidifying device to stop. In this way, through the humidity detection device, the humidity in the cleaning cavity is further detected. When the humidity information is greater than the preset humidity information, the dehumidifying device is controlled to continue operating, so that the dehumidifying device discharges the air with a higher humidity in the cleaning cavity outside the cabinet, thereby further reducing the humidity in the cleaning cavity.

[0013] When the humidity information is less than or equal to the preset humidity information, the controller controls the dehumidifying device to stop. In this way, after the humidity in the cleaning cavity reaches the preset humidity information, the controller can timely control the dehumidifying device to stop operating, thus avoiding the waste of energy consumption caused by the long-term operation of the dehumidifying device, enabling the dishwasher to achieve an energy-saving effect, and further enhancing the user experience.

[0014] In some embodiments, the dehumidifying device is a peristaltic pump. In this way, since the peristaltic pump is relatively easy to obtain and install, only need to install the peristaltic pump at the bottom of the dishwasher and connect the inlet of the peristaltic pump to the first water outlet connecting pipe, thus no large adjustment to the overall structure of the dishwasher is required, and the cost can be saved.

[0015] In some embodiments, along the vertical direction, the drainage container has a first side wall and a second side wall. The second side wall is located below the first side wall, and the drain outlet is provided on the second side wall. Along the direction from the second side wall to the first side wall, at least a part of the drainage cavity gradually increases in size in a dimension perpendicular to the vertical direction. In this way, the waste liquid flowing from the cleaning cavity to the drainage container will be located at the bottom of the drainage cavity after entering the drainage container, that is, the second side wall of the drainage container. Therefore, by providing the drain outlet on the second side wall, more waste liquid in the drainage cavity can flow out through the second drain outlet to the drainage pipe, so as to reduce the amount of residual water in the drainage cavity. In addition, along the direction from the second side wall to the first side wall, at least a part of the drainage cavity gradually increases in size in a dimension perpendicular to the vertical direction, which can further reduce the amount of residual water in the drainage cavity.

[0016] In some embodiments, along the vertical direction, the inner container has a bottom wall and a top wall. The bottom wall is located below the top wall, and the first drain outlet is provided on the bottom wall. Along the direction from the bottom wall to the top wall, at least a part of the cleaning cavity gradually increases in size in a dimension perpendicular to the vertical direction. In this way, during the tableware cleaning process, the waste liquid generated by cleaning the tableware will flow to the bottom of the cleaning cavity, that is, on the bottom wall of the inner container. Therefore, by providing the first drain outlet on the bottom wall, more waste liquid in the cleaning cavity can flow out through the first drain outlet to the drainage container, so as to reduce the amount of residual water in the cleaning cavity. In addition, along the direction from the bottom wall to the top wall, at least a part of the cleaning cavity gradually increases in size in a dimension perpendicular to the vertical direction, which can further reduce the amount of residual water in the cleaning cavity.

[0017] In some embodiments, the other end of the drainage hose is communicated with the drainage pipe, so that the other end of the drainage hose is communicated with the outside of the machine housing through the drainage pipe. In this way, during the operation of the dehumidifying device, the residual water and air sucked into the drainage hose can be discharged into the drainage pipe, so that the residual water and air flow through the drainage pipe and are discharged to the outside of the machine housing. In this way, the length of the drainage hose can be reduced, so as to further reduce the manufacturing cost of the dishwasher.

[0018] According to the second aspect of the present application, a dishwasher control method is provided, including controlling the dehumidifying device to operate after the washing program of the dishwasher ends; judging whether the water quantity information in the drainage container is greater than the preset water quantity information; if the water quantity information is greater than the preset water quantity information, controlling the dehumidifying device to continue to operate.

[0019] In some embodiments, the dishwasher control method further includes: judging whether the humidity information in the cleaning cavity is greater than the preset humidity information; if the humidity information is greater than the preset humidity information, controlling the dehumidifying device to continue to operate; if the humidity information is less than or equal to the preset humidity information, controlling the dehumidifying device to stop.

[0020] It should be noted that for the technical effects brought by the implementation manners of the second aspect, reference may be made to the technical effects brought by the corresponding implementation manners in the first aspect, which will not be elaborated herein.

In addition, when describing pipelines or channels, the terms "connected" and "coupled" used in this application have the meaning of conducting. The specific meaning needs to be understood in combination with the context.

[0049] In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or more advantageous than other embodiments or design solutions. Exactly speaking, using words such as "exemplary" or "for example" aims to present relevant concepts in a specific way.

[0050] The present application provides a dishwasher, as Figure 1 shown. The dishwasher includes a housing 1, an inner tank 2, and a drainage device 3. A receiving cavity 11 is formed inside the housing 1; the inner tank 2 is disposed inside the receiving cavity 11 and is connected to the housing 1. The housing 1 is used to protect the inner tank 2.

[0051] The inner tank 2 forms a cleaning cavity 21 and a first water outlet 22 communicating with the cleaning cavity 21; the drainage device 3 is connected to the first water outlet 22 and is used to drain the waste liquid inside the inner tank 2 to the outside of the housing 1. In this way, tableware can be placed in the cleaning cavity 21 for cleaning. When the tableware cleaning is completed, the waste liquid generated during the washing process can enter the drainage device 3 through the first water outlet 22 and be drained to the outside of the housing 1 through the drainage device 3.

[0052] In some examples, as Figure 2 shown, the drainage device 3 includes a drainage container 31 and a drainage pipe 32. The drainage container 31 forms a drainage cavity 311, an inlet 312, and a second water outlet 313 communicating with the drainage cavity 311; as Figure 3 shown, the inlet 312 communicates with the first water outlet 22; as Figure 2 shown, one end of the drainage pipe 32 communicates with the second water outlet 313, and the other end of the drainage pipe 32 is used to communicate with the outside of the housing 1.

[0053] In this way, after the dishwasher finishes washing the tableware, the waste liquid in the cleaning cavity 21 can enter the drainage container 31 through the water inlet 312, flow through the second water outlet 313 and enter the drainage pipe 32, and the waste liquid entering the drainage pipe 32 can be discharged to the outside of the machine housing 1 through the drainage pipe 32.

[0054] In some other examples, in order to facilitate controlling the drainage device 3 to discharge the waste liquid, on the basis that the drainage device 3 includes a drainage container 31 and a drainage pipe 32, the drainage device 3 may further include a drainage pump and a drainage valve, and both the drainage pump and the drainage valve are installed on the drainage pipe 32.

[0055] During the process of the dishwasher washing the tableware, the drainage valve is in a closed state and the drainage pump is in a shutdown state; after the dishwasher finishes washing the tableware, the drainage valve and the drainage pump are turned on to discharge the waste liquid in the cleaning cavity 21.

[0056] Among them, as Figure 4 shown, the first water outlet 22 can be arranged on the bottom wall 23 of the inner container 2, or can be arranged at the connection of the peripheral wall 24 and the bottom wall 23 of the inner container 2. Correspondingly, the drainage container 31 can be connected to the bottom wall 23 of the inner container 2, or can be connected to the connection of the peripheral wall 24 and the bottom wall 23 of the inner container 2. Among them, the water inlet 312 and the second water outlet 313 of the drainage container 31 can be arranged in the vertical direction, or can be arranged in the horizontal direction, or can be arranged in other directions.

[0057] For example, as Figure 4 shown, in the vertical direction, the inner container 2 has a bottom wall 23 and a top wall 25. The bottom wall 23 is located below the top wall 25, and the first water outlet 22 is arranged on the bottom wall 23. In this way, since during the process of washing the tableware, the waste liquid generated by washing the tableware will flow to the bottom of the cleaning cavity 21, that is, the bottom wall 23 of the inner container 2, therefore, by arranging the first water outlet 22 on the bottom wall 23, more waste liquid in the cleaning cavity 21 can flow out through the first water outlet 22 to the drainage container 31, so as to reduce the amount of residual water in the cleaning cavity 21.

[0058] In addition, in order to further reduce the amount of residual water in the cleaning cavity 21, along the direction from the bottom wall 23 to the top wall 25, at least part of the cleaning cavity 21 gradually increases in size in a direction perpendicular to the vertical direction.

[0059] In this way, the cleaning cavity 21 can be in the shape of a frustum of a cone, a cone or a frustum of a pyramid, and the area of the bottom wall 23 of the inner container 2 is smaller than the area of the top wall 25 of the inner container 2, so that the waste liquid in the cleaning cavity 21 can be more concentrated at the bottom of the cleaning cavity 21, so that more waste liquid in the cleaning cavity 21 can flow to the drainage container 31 through the first water outlet 22, thereby further reducing the amount of residual water in the inner container 2.

[0060] On this basis, in order to reduce the amount of residual water in the drainage container 31, as Figure 5 shown, the drainage container 31 is connected to the bottom wall 23 of the inner container 2. In the vertical direction, as Figure 6 shown, the drainage container 31 has a first side wall 314 and a second side wall 315. The second side wall 315 is located below the first side wall 314, and the drain outlet 316 is provided on the second side wall 315. In this way, the waste liquid flowing from the cleaning chamber 21 to the drainage container 31 will be located at the bottom of the drainage chamber 311, that is, the second side wall 315 of the drainage container 31, after entering the drainage container 31. Therefore, by providing the drain outlet 316 on the second side wall 315, more waste liquid in the drainage chamber 311 can flow out through the second water outlet 313 to the drainage pipe 32, so as to reduce the amount of residual water in the drainage chamber 311.

[0061] In addition, in order to further reduce the amount of residual water in the drainage chamber 311, at least part of the drainage chamber 311 gradually increases in size in a direction perpendicular to the vertical direction along the direction from the second side wall 315 to the first side wall 314.

[0062] In this way, the drainage chamber 311 can be in the shape of a frustum of a cone, a cone or a frustum of a pyramid, and the area of the second side wall 315 of the drainage container 31 is smaller than the area of the first side wall 314 of the drainage container 31, so that the waste liquid in the drainage chamber 311 can be more concentrated at the bottom of the drainage chamber 311, so that more waste liquid in the drainage chamber 311 can flow to the drainage pipe 32 through the second water outlet 313, thereby further reducing the amount of residual water in the drainage container 31.

[0063] After the waste liquid in the cleaning chamber 21 and the drainage chamber 311 is discharged through the drainage device 3, residual water will still adhere to the side wall 24 (the top wall 25, the bottom wall 23 and the peripheral wall 24 of the cleaning chamber 21) of the cleaning chamber 21, and on the side wall 24 (the top wall, the bottom wall and the peripheral wall of the drainage chamber 311) of the drainage chamber 311, and there will also be more water vapor mixed in the air of the cleaning chamber 21 and the drainage chamber 311, which will cause bacteria to breed in the cleaning chamber 21 and the drainage chamber 311.

[0064] Based on this, as Figure 7 shown, the dishwasher further includes a dehumidifying device 4. The dehumidifying device 4 is connected to the machine housing 1; the dehumidifying device 4 includes a driving part 41 and a drainage hose 42. One end of the drainage hose 42 is communicated with the first water outlet 22, and the other end of the drainage hose 42 is used for communicating with the outside of the machine housing 1; the driving part 41 is connected to the drainage hose 42 and is used for squeezing the drainage hose 42 along the radial direction of the drainage hose 42 and squeezing the peripheral wall of the drainage hose 42 along the direction of the medium flow in the drainage hose 42 to drive the medium in the drainage hose 42 to flow.

[0065] In this way, after the dishwasher finishes washing, the dehumidifying device 4 can be activated to squeeze the drain hose 42 along the radial direction of the drain hose 42 by the driving part 41 of the dehumidifying device 4, and squeeze the peripheral wall of the drain hose 42 along the direction of the medium flow in the drain hose 42, so that the driving part 41 continuously squeezes the air in the drain hose 42, and continuously discharges the air in the drain hose 42 from the other end of the drain hose 42 to the outside of the machine housing 1.

[0066] Every time the driving part 41 discharges the air in the drain hose 42 to the outside of the machine housing 1, the air pressure in the drain hose 42 will be lower than the air pressure in the cleaning cavity 21, so that the air in the cleaning cavity 21 can be sucked into the drain hose 42. In this way, during the process that the driving part 41 continuously repeats squeezing the drain hose 42, the air in the cleaning cavity 21 can be gradually sucked into the drain hose 42 and discharged from the drain hose 42 to the outside of the machine housing 1.

[0067] When the air in the cleaning cavity 21 is discharged to the outside of the machine housing 1, it can take away the moisture and residual water in the cleaning cavity 21, thereby reducing the humidity in the cleaning cavity 21, preventing bacteria from growing in the inner liner 2, and further improving the user experience.

[0068] Exemplarily, as Figure 7 shown, the dehumidifying device 4 can be a peristaltic pump 43. The peristaltic pump 43 is relatively easy to obtain and install. In this way, it only needs to install the peristaltic pump 43 at the bottom of the dishwasher and connect the inlet of the peristaltic pump 43 to the first water outlet 22 communicating pipe, so that it is not necessary to make major adjustments to the overall structure of the dishwasher, and thus the cost can be saved.

[0069] It can be understood that the peristaltic pump 43 generally includes a drain hose 42 and a pump body 431. One end of the drain hose 42 is connected to the drain port 316, the other end of the drain hose 42 passes through the pump body 431 and communicates with the outside of the machine housing 1. The pump body 431 includes a compression wheel and a motor. The motor drives the compression wheel to rotate through a rotating shaft. During the rotation of the compression wheel, it can intermittently and repeatedly squeeze the drain hose 42, that is, squeeze the drain hose 42 along the radial direction of the drain hose 42, and squeeze the peripheral wall of the drain hose 42 along the direction of the medium flow in the drain hose 42, so that the drain hose 42 continuously sucks the air in the cleaning cavity 21 into the drain hose 42 and discharges it to the outside of the machine housing 1.

[0070] In addition, the peristaltic pump 43 can run idly. When the residual water in the inner liner 2 is discharged from the machine housing 1, the peristaltic pump 43 can continue to operate to discharge the air with higher humidity in the cleaning cavity 21, thereby increasing the drying degree of the cleaning cavity 21 and reducing the growth of bacteria in the cleaning cavity 21.

[0071] Exemplarily, as Figure 8As shown, the dehumidifying device 4 may include a belt drive structure 44, a pressing block 45, and a drainage hose 42. In this way, the pressing block 45 is connected to the belt drive structure 44. When the belt drive structure 44 rotates, it drives the pressing block 45 to move. During the rotation of the belt drive structure 44, the pressing block 45 can intermittently press the peripheral wall of the drainage hose 42 along the direction of the medium flow in the drainage hose 42, that is, press the drainage hose 42 radially. One end of the drainage hose 42 is connected to the first water outlet 22, and the other end of the drainage hose 42 communicates with the outside of the machine housing 1. This can continuously suck the air in the cleaning chamber 21 into the drainage hose 42 and discharge it to the outside of the machine housing 1.

[0072] Among them, as Figure 7 shown, one end of the drainage hose 42 can be directly communicated with the first water outlet 22; as Figure 9 shown, one end of the drainage hose 42 can also be communicated with the first water outlet 22 through a drainage container 31. The other end of the drainage hose 42 can directly extend out of the machine housing 1 so that the other end of the drainage hose 42 communicates with the outside of the machine housing 1; as Figure 10 shown, the other end of the drainage hose 42 can also be communicated with the outside of the machine housing 1 through a drainage pipe 32.

[0073] Exemplarily, as Figure 6 shown, the drainage container 31 is also formed with a drainage port 316 communicating with the drainage chamber 311. As Figure 11 shown, one end of the drainage hose 42 communicates with the drainage port 316 of the drainage container 31 so that one end of the drainage hose 42 communicates with the first water outlet 22 through the drainage container 31.

[0074] In this way, during the working process of the dehumidifying device 4, it can also discharge the relatively humid air and residual water in the drainage chamber 311 to the outside of the machine housing 1. Thus, while the dehumidifying device 4 dehumidifies the cleaning chamber 21, it can also dehumidify the drainage chamber 311, so that the dehumidifying device 4 has multiple uses, thereby saving the manufacturing cost of the dishwasher.

[0075] Exemplarily, as Figure 10 shown, the other end of the drainage hose 42 communicates with the drainage pipe 32 so that the other end of the drainage hose 42 communicates with the outside of the machine housing 1 through the drainage pipe 32.

[0076] In this way, during the working process of the dehumidifying device 4, it can discharge the residual water and air sucked into the drainage hose 42 into the drainage pipe 32, so that the residual water and air flow through the drainage pipe 32 and are discharged to the outside of the machine housing 1. In this way, the length of the drainage hose 42 can be reduced, further reducing the manufacturing cost of the dishwasher.

[0077] In addition, the drainage pipe 32 is usually connected to the sewer pipe. After the residual water flows through the drainage pipe 32, it can be discharged into the sewer pipe, which can facilitate the user's unified treatment of the waste liquid and avoid polluting the environment outside the cabinet 1 after the residual water is discharged outside the cabinet 1, thereby improving the user's experience.

[0078] It should be noted that in order to balance the air pressure inside and outside the dishwasher, a pressure regulating device, such as a breather, is usually equipped for the dishwasher.

[0079] Specifically, the breather has an exhaust pipe and a breathing valve. The exhaust pipe is connected to the exhaust port of the inner container 2 of the dishwasher, and the breathing valve is arranged on the exhaust pipe.

[0080] When the dishwasher generates hot air during operation, the breather discharges the hot air inside the inner container 2 to the outside of the inner container 2 through the exhaust pipe, thereby reducing the internal air pressure of the inner container 2. In addition, when the internal air pressure of the inner container 2 is low, the breather can also inhale the outside air into the inner container 2 to keep the internal air pressure of the inner container 2 within a suitable range.

[0081] In this way, during the process of the dehumidifying device 4 discharging the air inside the cleaning chamber 21 from the cleaning chamber 21, the breather can keep the air pressure balance inside and outside the cleaning chamber 21, so that the dehumidifying device 4 can continuously operate without being affected by the air pressure.

[0082] In some embodiments, to enhance the operation convenience of the dishwasher, as Figure 12 shown, the dishwasher further includes a water quantity detection device 5 and a controller 6. The water quantity detection device 5 is arranged in the drainage chamber 311 and is connected to the drainage container 31 for detecting the water quantity information in the drainage chamber 311. Among them, the water quantity detection device 5 can be a pressure sensor, a capacitance sensor, or an ultrasonic sensor.

[0083] Exemplarily, the water quantity detection device 5 is a pressure sensor. At this time, the pressure sensor is installed on the bottom wall 23 of the drainage chamber 311, and the water quantity information is determined by measuring the water pressure of the residual water in the drainage chamber 311 through the pressure sensor.

[0084] The controller 6 is connected to both the dehumidifying device 4 and the water quantity detection device 5. The controller 6 can obtain the water quantity information detected by the water quantity detection device 5; the controller 6 is configured to: after the washing program of the dishwasher ends, control the dehumidifying device 4 to operate; judge whether the water quantity information is greater than the preset water quantity information; if the water quantity information is greater than the preset water quantity information, then control the dehumidifying device 4 to continue to operate. Among them, the preset water quantity information can be set according to the requirements of different dishwashers. For example, the preset water quantity information can be 5ml, 6ml, 7ml, 8ml, 9ml, 10ml, etc.

[0085] In this way, after the washing program of the dishwasher ends, the dehumidifying device 4 is controlled by the controller 6 to run, which improves the automation degree of the dishwasher, enhances the convenience of controlling the dehumidifying device 4, and facilitates the timely startup of the dehumidifying device 4, so that the dishwasher can drain residual water and moisture more promptly through the dehumidifying device 4, thereby being more conducive to avoiding the growth of bacteria in the inner tank 2. Moreover, through the water quantity detection device 5, the water quantity information of the residual water in the drainage cavity 311 can be detected in real time, so that the controller 6 can obtain the water quantity information of the residual water in the drainage cavity 311 in real time, facilitating the controller 6 to promptly know whether the water quantity information of the residual water in the drainage cavity 311 meets the requirements, and thus facilitating the controller 6 to control the operation of the dehumidifying device 4 according to the water quantity information, so as to make the control of the dehumidifying device 4 more refined.

[0086] It should be noted that the controller 6 can judge whether the washing program ends according to the washing time of a washing program of the dishwasher. Specifically, different washing programs of the dishwasher have different preset washing times. Therefore, the time information from the start to the end of the washing program can be calculated by a timer and transmitted to the controller 6 so that the controller 6 can receive this time information. If the time information received by the controller 6 is greater than or equal to the preset washing time of the washing program, it is judged that the washing program ends; otherwise, it is judged that the washing program has not ended.

[0087] The controller 6 can judge whether the washing program ends according to the temperature change during the operation of a washing program of the dishwasher. Specifically, different washing programs of the dishwasher are carried out within different temperature ranges, that is, different washing programs of the dishwasher correspond to different preset temperature ranges. Therefore, the temperature information in the cleaning cavity 21 can be detected by a temperature sensor and transmitted to the controller 6 so that the controller 6 can receive this temperature information. When the temperature information received by the controller 6 is within the preset temperature range corresponding to the washing program, it indicates that the washing program has not ended; otherwise, it indicates that the washing program ends.

[0088] On this basis, if the controller 6 judges that the water quantity information is less than or equal to the preset water quantity information, it means that the water quantity of the residual water in the drainage cavity 311 is small and the humidity in the drainage cavity 311 meets the requirements. Moreover, since the drainage cavity 311 is connected to the cleaning cavity 21, it can also indicate that the water quantity of the residual water in the cleaning cavity 21 is small. At this time, the operation of the dehumidifying device 4 can be controlled to stop, or the humidity in the cleaning cavity 21 can be further detected to control the dehumidifying device 4 according to the humidity in the cleaning cavity 21.

[0089] Exemplarily, such as Figure 13As shown, the dishwasher further includes a humidity detection device 7. The humidity detection device 7 is disposed in the washing cavity 21 and connected to the inner container 2 for detecting the humidity information in the washing cavity 21. Among them, the humidity detection device 7 can be an infrared humidity sensor, a capacitive humidity sensor, or a conductive humidity sensor.

[0090] Exemplarily, the humidity detection device 7 is an infrared humidity sensor. The infrared humidity sensor is disposed in the washing cavity 21 and connected to the inner container 2. When water molecules in the air come into contact with the surface of the infrared humidity sensor, the infrared energy will be absorbed by the water molecules in the air, resulting in a change in the resistance value on the infrared humidity sensor. The infrared humidity sensor determines the humidity information in the inner container 2 by measuring the resistance value, so that the controller 6 can obtain the humidity information in the inner container 2 measured by the infrared humidity sensor.

[0091] The controller 6 is also connected to the humidity detection device 7 for obtaining the humidity information detected by the humidity detection device 7. The controller 6 is further configured to: determine whether the humidity information is greater than a preset humidity information; if the humidity information is greater than the preset humidity information, control the dehumidifying device 4 to continue running; if the humidity information is less than or equal to the preset humidity information, control the dehumidifying device 4 to stop.

[0092] Among them, the preset humidity information can be set according to the requirements of different dishwashers. For example, the preset humidity information can be RH50%, RH45%, RH40%, RH35%, etc.

[0093] In this way, the humidity in the washing cavity 21 is further detected by the humidity detection device 7. When the humidity information is greater than the preset humidity information, the dehumidifying device 4 is controlled to continue running, so that the dehumidifying device 4 discharges the air with higher humidity in the washing cavity 21 to the outside of the housing 1, thereby further reducing the humidity in the washing cavity 21.

[0094] When the humidity information is less than or equal to the preset humidity information, the controller 6 controls the dehumidifying device 4 to stop. In this way, after the humidity in the washing cavity 21 reaches the preset humidity information, the controller 6 can timely control the dehumidifying device 4 to stop running, thereby avoiding waste of energy consumption caused by long-term operation of the dehumidifying device 4, enabling the dishwasher to achieve an energy-saving effect, and further enhancing the user experience.

[0095] The present invention also provides a dishwasher control method, as Figure 14 shown, the dishwasher control method includes:

[0096] S1: After the washing program of the dishwasher ends, control the dehumidifying device 4 to run.

[0097] S2: Determine whether the water volume information in the drainage container 31 is greater than a preset water volume information.

[0098] S3: If the water quantity information is greater than the preset water quantity information, control the dehumidifying device 4 to continue operating.

[0099] In this way, after the washing program of the dishwasher ends, the waste liquid in the washing cavity 21 starts to flow towards the drainage container 31, then flows towards the drainage pipe 32 through the second water outlet 313 of the drainage container 31. By operating the dehumidifying device 4 through the controller 6, the waste liquid in the drainage container 31 can be discharged from the drainage container 31 through the dehumidifying device 4. When the remaining amount of the waste liquid in the drainage container 31 is small, at this time, a small amount of residual water cannot flow out of the drainage container 31 through the second water outlet 313 independently. Operating the dehumidifying device 4 can suck the residual water in the drainage container 31 into the drainage hose 42 and discharge it outside the machine housing 1, thereby reducing the residual water in the drainage container 31.

[0100] In addition, the controller 6 determines whether the water quantity information in the drainage container 31 is greater than the preset water quantity information. If the water quantity information is greater than the preset water quantity information, the controller 6 controls the dehumidifying device 4 to continue operating so that the residual water quantity in the drainage container 31 is lower than the preset water quantity information, thereby enabling the water quantity in the drainage container 31 to be maintained at a relatively low level, and thus being able to avoid the growth of bacteria in the inner tank 2.

[0101] In some embodiments, as Figure 15 shown, the dishwasher control method further includes:

[0102] S10: Determine whether the humidity information in the washing cavity 21 is greater than the preset humidity information.

[0103] S20: If the humidity information is greater than the preset humidity information, control the dehumidifying device 4 to continue operating; if the humidity information is less than or equal to the preset humidity information, control the dehumidifying device 4 to stop.

[0104] In this way, the controller 6 determines whether the humidity information in the washing cavity 21 is greater than the preset humidity information to control the dehumidifying device 4 so that the dehumidifying device 4 stops when the humidity information in the washing cavity 21 is less than or equal to the preset humidity information. Thus, after the washing program ends, the dehumidifying device 4 can reduce the humidity in the washing cavity 21 to the preset humidity information or below the preset humidity information, which is further more conducive to avoiding the growth of bacteria in the inner tank 2. In addition, when the humidity information is less than or equal to the preset humidity information, the controller 6 can timely control the dehumidifying device 4 to stop operating, thereby avoiding the waste of energy consumption caused by the long-term operation of the dehumidifying device 4, enabling the dishwasher to achieve an energy-saving effect, and further enhancing the user experience.

[0105] It should be noted that the steps in this embodiment can be executed independently. The steps in this embodiment can also be executed after determining whether the water volume information in the drainage container 31 is greater than the preset water volume information. Specifically, as Figure 16 shown, the dishwasher control method further includes:

[0106] S1a: After the washing program of the dishwasher ends, control the dehumidifying device 4 to operate.

[0107] S2a: Determine whether the water volume information in the drainage container 31 is greater than the preset water volume information.

[0108] S3a: If the water volume information is greater than the preset water volume information, control the dehumidifying device 4 to continue operating;

[0109] S4a: If the water volume information is less than or equal to the preset water volume information, determine whether the humidity information in the cleaning chamber 21 is greater than the preset humidity information.

[0110] S5a: If the humidity information is greater than the preset humidity information, control the dehumidifying device 4 to continue operating; if the humidity information is less than or equal to the preset humidity information, control the dehumidifying device 4 to stop.

[0111] In this way, after the washing program of the dishwasher ends, the controller 6 controls the dehumidifying device 4 to operate so that the dehumidifying device 4 can drain the waste liquid in the drainage container 31 to the outside of the machine housing 1. During this process, the controller 6 determines whether the water volume information in the drainage container 31 is greater than the preset water volume information, so that the controller 6 can control the dehumidifying device 4 to reduce the water volume in the drainage container 31 to the preset water volume information and below. Then, the controller 6 continues to determine whether the humidity information in the cleaning chamber 21 is greater than the preset humidity information, so that the controller 6 can control the dehumidifying device 4 to reduce the humidity in the cleaning chamber 21 to the preset humidity information and below. Then, the controller 6 controls the dehumidifying device 4 to stop. Since the cleaning chamber 21 and the drainage chamber 311 are connected, through the operation of the dehumidifying device 4, the water volume and humidity information in both the cleaning chamber 21 and the drainage chamber 311 are reduced to the preset water volume information and the preset humidity information and below. This will further prevent bacteria from breeding in the inner container 2. At the same time, the controller 6 timely controls the dehumidifying device 4 to stop, which can avoid waste of energy consumption caused by the long-term operation of the dehumidifying device 4, so that the dishwasher can achieve an energy-saving effect.
