Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of dishwashers, in particular, relates to a dishwasher noise control method and a dishwasher. BACKGROUND

[0002] A dishwasher is an automatic device for cleaning dishes, chopsticks, plates, and other tableware. With the improvement of people's living standards, dishwashers are increasingly used in more and more families. They can reduce the labor intensity of users, improve work efficiency, and improve cleanliness to meet the experience of users' comfortable life.

[0003] Currently, the increasing demand of users for high quality of life has conflicted with the experience of dishwasher products. For example, dishwashers improve the quality of life of users, but have the problem of loud noise. The existing noise control method does not meet the user's requirements for dishwasher noise control, and cannot balance cleaning effect and silence.

[0004] Therefore, the present application is proposed. SUMMARY

[0005] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art and provide a dishwasher noise control method and a dishwasher. The dishwasher automatically adjusts and improves the washing action according to the noise detection value and the cleaning effect detection value, and determines the optimal washing action, thereby achieving automatic control of the dishwasher to balance the cleaning effect and noise.

[0006] To solve the above technical problems, the basic idea of the technical solution of the present application is:

[0007] The present application provides a dishwasher noise control method, comprising:

[0008] obtaining a noise target value and a target cleaning effect, and determining a first washing action corresponding to the noise target value and the target cleaning effect;

[0009] The dishwasher executes the first washing action, and during the execution, detects the noise and cleaning effect of the dishwasher to obtain a first noise detection value and a first cleaning effect detection value;

[0010] Comparing the first noise detection value with the noise target value and the first cleaning effect detection value with the target cleaning effect, and adjusting the first washing action according to the two comparison results, the adjusted first washing action is defined as a second washing action;

[0011] The dishwasher executes the second washing action, and during the execution, continues to detect the noise and cleaning effect of the dishwasher to obtain a second noise detection value and a second cleaning effect detection value;

[0012] The dish washing machine determines the second washing action as the optimal washing action when the second noise detection value does not exceed the noise target value and the second cleaning effect detection value meets the cleaning effect detection value.

[0013] The dish washing machine automatically adjusts and improves the washing action according to the noise detection value and the cleaning effect detection value, and determines the optimal washing action, so as to realize the automatic control of the dish washing machine with the balance of the cleaning effect and the noise as the target.

[0014] Further, the dish washing machine executes the second washing action, detects the noise and the cleaning effect of the dish washing machine multiple times during the execution, and obtains the second noise detection value and the second cleaning effect detection value multiple times.

[0015] After obtaining the second noise detection value and the second cleaning effect detection value each time, the second noise detection value and the noise target value are compared, and the second cleaning effect detection value and the target cleaning effect are compared, and the second washing action is adjusted according to the two comparison results.

[0016] The dish washing machine stops obtaining the second noise detection value and the second cleaning effect detection value when the second noise detection value does not exceed the noise target value and the second cleaning effect detection value meets the cleaning effect detection value, and determines the current second washing action as the optimal washing action.

[0017] The above scheme further realizes the automatic control of the dish washing machine.

[0018] Further, the dish washing machine is provided with at least one spraying arm.

[0019] The adjustment of the first washing action and the adjustment of the second washing action include adjustment of the water outlet pressure value and / or the spraying arm action mode.

[0020] If the first noise detection value or the second noise detection value is greater than the noise target value, the water outlet pressure value is reduced, or the spraying arm action mode is adjusted.

[0021] If the first noise detection value or the second noise detection value is less than or equal to the noise target value, and the first cleaning effect detection value or the second cleaning effect detection value does not meet the target cleaning effect, the water outlet pressure value is increased, or the spraying arm action mode is adjusted.

[0022] The above scheme realizes the automatic control of the water outlet pressure value and / or the spraying arm action mode of the dish washing machine with the balance of the cleaning effect and the noise as the target, and provides the best user experience.

[0023] Further, the dish washing machine is provided with at least two spraying arms with independent actions.

[0024] The spray arm action mode includes a single spray arm action mode and a plurality of spray arm combined action modes.

[0025] During execution of the set washing action by the dishwasher, one of the single spray arm action mode and the plurality of spray arm combined action modes is determined to be executed.

[0026] If the first noise detection value or the second noise detection value is greater than the noise target value, the water outlet pressure value is reduced, or the single spray arm action mode is adjusted to be executed.

[0027] If the first noise detection value or the second noise detection value is less than or equal to the noise target value, and the first cleaning effect detection value or the second cleaning effect detection value does not satisfy the target cleaning effect, the water outlet pressure value is correspondingly increased, or the plurality of spray arm combined action modes is adjusted to be executed.

[0028] In the above scheme, automatic control of the dishwasher with a plurality of spray arms for better cleaning effect and balancing cleaning effect and noise is achieved.

[0029] A further scheme of the present application is that the dishwasher is provided with four independently acting spray arms, of which two are a first spray arm group and the other two are a second spray arm group.

[0030] The plurality of spray arm combined action modes includes alternating action of the first spray arm group and the second spray arm group, and / or single action of one of the first spray arm group or the second spray arm group.

[0031] In the above scheme, automatic control of the dishwasher with four spray arms, such as automatic control of the four-quadrant waterway dishwasher, is achieved.

[0032] A further scheme of the present application is that the adjustment of the first washing action and the second washing action further includes adjustment of the drainage time length.

[0033] If the first noise detection value or the second noise detection value is greater than the noise target value, the drainage time length is shortened, or the water outlet pressure value is reduced, or the spray arm action mode is adjusted.

[0034] In the above scheme, when the noise detection value is greater than the noise target value, the drainage time length can be shortened, which achieves reduction of the noise of the dishwasher without reducing the cleaning effect.

[0035] A further scheme of the present application is that the dishwasher obtains the state of tableware, and comprehensively determines the set washing action according to the state of tableware, the noise target value and the target cleaning effect.

[0036] In the above scheme, the automatic control of the set washing action that is easier to meet the noise target value and the target cleaning effect is realized.

[0037] The application further provides a dishwasher comprising:

[0038] A shelf for placing tableware;

[0039] At least two independently horizontally rotating spray arms, and the at least two spray arms are located on the same side of the shelf.

[0040] The dishwasher of the application realizes better spraying effect through the at least two spray arms, and avoids water and time consumption caused by spraying the entire shelf by a single spray arm when the tableware does not fill the entire shelf.

[0041] In a further scheme of the application, four spray arms are arranged below the shelf, the four spray arms are arranged at the same horizontal height, and at least two spray arms are in contact with each other when the four spray arms rotate simultaneously.

[0042] The dishwasher comprises a spray arm detection module for detecting the position of the spray arm.

[0043] A control module in communication connection with the spray arm detection module, according to the position of the spray arm detected by the spray arm detection module, the four spray arms do not contact each other when performing a plurality of spray arm combination action modes.

[0044] In the above scheme, the four spray arms are closely arranged, and the space occupied by the four spray arms is reduced.

[0045] In a further scheme of the application, a noise detection module is arranged for detecting a noise detection value generated by the dishwasher.

[0046] A cleaning effect detection module is arranged for detecting a cleaning effect detection value of the tableware in the shelf.

[0048] In the above scheme, the dishwasher realizes automatic adjustment and improvement of the washing action according to the noise detection value and the cleaning effect detection value.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0069] As Figures 1 to 5 shown, the present application provides a dish washing machine noise control method and a dish washing machine. By means of the dish washing machine, the automatic adjustment and improvement of the washing action are realized according to the noise detection value and the cleaning effect detection value, and the optimal washing action is determined, so that the automatic test of the dish washing machine with the balanced cleaning effect and noise as the target is realized, the manual test amount of the research and development personnel is greatly reduced, and the research and development process and the listing time of the dish washing machine are accelerated.

[0070] Embodiment one

[0071] As Figures 1 to 5As shown, the embodiment provides a dish washing machine noise control method, comprising: obtaining a noise target value and a target cleaning effect, determining a first washing action corresponding to the noise target value and the target cleaning effect; the dish washing machine executes the first washing action, and detects the noise and the cleaning effect of the dish washing machine during the execution process to obtain a first noise detection value and a first cleaning effect detection value; comparing the first noise detection value with the noise target value and the first cleaning effect detection value with the target cleaning effect, adjusting the first washing action according to the two comparison results, defining the adjusted first washing action as a second washing action; the dish washing machine executes the second washing action, and continues to detect the noise and the cleaning effect of the dish washing machine during the execution process to obtain a second noise detection value and a second cleaning effect detection value; the dish washing machine determines the second washing action as an optimal washing action when the second noise detection value does not exceed the noise target value and the second cleaning effect detection value meets the cleaning effect detection value.

[0072] By adjusting and improving the washing action automatically according to the noise detection value and the cleaning effect detection value, and determining the optimal washing action, the automatic control of the dish washing machine with the balance of the cleaning effect and the noise as the target is realized. The noise control method can be used in the test of the dish washing machine, especially the prototype test, or in the operation of the dish washing machine to provide the best user experience.

[0073] It can be understood that the noise of the dish washing machine can be detected by a decibel sensor, the image containing the tableware in the dish washing machine can be obtained by an image sensor, the area of the tableware and the proportion of the oil stain part in the area of the tableware can be obtained by an image recognition algorithm, and then the cleaning effect detection value can be obtained, at this time, the target cleaning effect is a set upper limit value of the proportion.

[0074] It should be noted that in the cleaning program of the dishwasher, the noise target value and the target cleaning effect are respectively corresponding to the first washing action. The correspondence can be that two first washing actions are derived according to the noise interval in which the noise target value is located and the interval in which the target cleaning effect is located, that is, the noise target value and the target cleaning effect have a mapping relationship with the first washing action, for example, the spray action and the water pressure value of the first washing action. It can be understood that the correspondence can be a preset program of the dishwasher that needs to be tested and adjusted, or the correspondence is derived by the researchers according to the existing experimental data and input into the dishwasher. The first washing action determined by the dishwasher according to the noise target value and the target cleaning effect can be one of the two corresponding first washing actions, or a comprehensive value of the two first washing actions, for example, the noise target value corresponds to the first water pressure value of the first washing action, and the target cleaning effect corresponds to the second water pressure value. The final water pressure value can be the larger value, the smaller value, the average value or the weighted average value of the first water pressure value and the second water pressure value, and the spray action is preferably the one with smaller noise among the corresponding spray actions to facilitate adjustment according to the noise detection value.

[0075] In the embodiment, the washing action includes the first washing action and the second washing action, the noise detection value includes the first noise detection value and the second noise detection value, and the cleaning effect detection value includes the first cleaning effect detection value and the second cleaning effect detection value. It can be understood that the dishwasher detects and obtains the noise detection value and the cleaning effect detection value, respectively corresponding analyzes and judges the noise target value and the target cleaning effect, and determines whether to adjust the washing action and determines the optimal washing action according to the two judgment results. The process constitutes an open-loop automatic control system, that is, according to the comparison of the second noise detection value and the noise target value, and the comparison of the second cleaning effect detection value and the target cleaning effect, the second washing action is adjusted according to the two comparison results, which is repeatedly executed. The process of continuously adjusting the parameters is specifically through a mathematical model including a control algorithm to obtain the optimal parameters of the dishwasher system by adjusting the parameters multiple times, thereby reducing the workload and uncertainty of manual adjustment of the washing action and its parameters by the researchers.

[0076] It can be understood that the optimal washing action can be the best cleaning effect of the dishwasher on the basis that the noise detection value meets the qualified noise level or the expected noise level, that is, the dishwasher realizes the automatic test with balanced cleaning effect and noise as the target.

[0077] In the embodiment, the dish washing machine performs the second washing action, and detects the noise and the cleaning effect of the dish washing machine multiple times during the execution process, and obtains the second noise detection value and the second cleaning effect detection value multiple times; after obtaining the second noise detection value and the second cleaning effect detection value each time, the second noise detection value and the noise target value are compared, and the second cleaning effect detection value and the target cleaning effect are compared, and the second washing action is adjusted according to the two comparison results; when the dish washing machine judges that the second noise detection value does not exceed the noise target value and the second cleaning effect detection value meets the cleaning effect detection value, the dish washing machine stops obtaining the second noise detection value and the second cleaning effect detection value, and determines the current second washing action as the optimal washing action. The automatic testing of the dish washing machine is further realized.

[0078] In the embodiment, the dish washing machine is provided with at least one spray arm; the adjustment of the first washing action and the adjustment of the second washing action include: adjusting the water outlet pressure value and / or the spray arm action mode; if the first noise detection value or the second noise detection value is greater than the noise target value, the water outlet pressure value is reduced, or the spray arm action mode is adjusted; if the first noise detection value or the second noise detection value is less than or equal to the noise target value, and the cleaning effect detection value does not meet the target cleaning effect, the water outlet pressure value is increased, or the spray arm action mode is adjusted.

[0079] Further, the spray arm action mode can include the rotation speed of the spray arm, the water spraying interval duration and the like. It can be understood that the first noise detection value or the second noise detection value in the embodiment can be the average noise level generated by the washing action within a period of time, rather than the noise value at a single moment, because the noise value at a single moment cannot represent the actual use experience of the user and the noise detection regulation of the dish washing machine in the relevant industry standard. Therefore, when the water spraying interval duration is unchanged, the dish washing machine can obtain the optimal parameters of the water outlet pressure value and the rotation speed of the spray arm through multiple tests and adjustments by using a mathematical model including a control algorithm, and the optimal washing action includes the optimal parameters of the water outlet pressure value and the rotation speed of the spray arm in the water spraying interval duration.

[0080] It can be understood that the water outlet pressure value can be actually determined by the water pump and the valve corresponding to the spray arm.

[0081] In the embodiment, the dishwasher is provided with at least two spray arms capable of independent action; the spray arm action modes include a single spray arm action mode and a plurality of spray arm combined action modes; during the execution of the washing action by the dishwasher, one of the single spray arm action mode and the plurality of spray arm combined action modes is determined to be executed; if the first noise detection value or the second noise detection value is greater than the noise target value, the water outlet pressure value is reduced, or the single spray arm action mode is adjusted to be executed; if the first noise detection value or the second noise detection value is less than or equal to the noise target value, and the first cleaning effect detection value or the second cleaning effect detection value does not satisfy the target cleaning effect, the water outlet pressure value is correspondingly increased, or the plurality of spray arm combined action modes is adjusted to be executed. Thus, the automatic testing of the dishwasher with multiple spray arms and better cleaning effect is realized, and the manual testing amount of the dishwasher with multiple spray arms is greatly reduced.

[0082] In some possible embodiments, when the first noise detection value or the second noise detection value does not exceed the noise target value, and the first cleaning effect detection value or the second cleaning effect detection value does not satisfy the target cleaning effect, the single spray arm action mode is changed to the plurality of spray arm combined action mode. Thus, under the condition that the noise value meets the standard requirement, the dishwasher can automatically switch between the single spray arm action mode and the plurality of spray arm combined action mode to perform a more suitable washing action.

[0083] In other possible embodiments, the single spray arm action mode and the plurality of spray arm combined action mode are tested respectively, that is, when the dishwasher executes the single spray arm action mode, a mathematical model applied to a control system is used to adjust the water outlet pressure value, the rotation speed of the spray arm or the water spraying interval length by taking the noise detection value or the cleaning effect detection value as an input variable, combining the noise target value and the target cleaning effect, and taking the adjusted three variables as output variables, and then the noise detection value or the cleaning effect detection value is detected again and obtained, which is input into the control system until the optimal washing action under the single spray arm action mode is finally obtained; when the dishwasher switches to execute the plurality of spray arm combined action mode, the above process is performed. Thus, the optimal washing action of the plurality of spray arm action modes can be obtained respectively.

[0084] In the embodiment, the dishwasher is provided with four spray arms capable of independent action, two of which form a first spray arm group, and the other two form a second spray arm group; the plurality of spray arm combined action modes include the alternating action of the first spray arm group and the second spray arm group, and / or the single action of one of the first spray arm group or the second spray arm group. Thus, the automatic testing of the dishwasher with four spray arms is realized, and the manual testing amount of the dishwasher with four spray arms is greatly reduced.

[0085] In particular, the test method is preferably applied to a four-quadrant waterway dishwasher as shown in Figures 3 to 5 As the front spray arm 33 and the rear spray arm 33 are in contact when they rotate simultaneously, the automatic test of the dishwasher in which the spray arms 33 can contact each other and fully cover the spray is realized by grouping the plurality of spray arms 33 and combining the action modes.

[0086] In this embodiment, the adjustment of the first washing action and the adjustment of the second washing action further include adjusting the drainage time length; if the first noise detection value or the second noise detection value is greater than the noise target value, the drainage time length is shortened, or the water outlet pressure value is reduced, or the spray arm action mode is adjusted. Therefore, by selecting to shorten the drainage time length when the noise detection value is greater than the noise target value, the noise of the dishwasher is reduced without reducing the cleaning effect.

[0087] It can be understood that shortening the drainage time length will increase the drainage amount and the noise value in a short period of time, but will reduce the noise detection value generated in a period of time including drainage.

[0088] In some possible embodiments, when the dishwasher determines that the noise detection value cannot be less than or equal to the noise target value by adjusting the parameters and the spray arm action after the water outlet pressure value is reduced and the spray arm action mode is adjusted for a first set number of times, the dishwasher selects to shorten the drainage time length, otherwise the drainage time length is not adjusted.

[0089] In this embodiment, the adjustment of the first washing action and the adjustment of the second washing action further include adjusting the drainage time length; if the first noise detection value or the second noise detection value is greater than the noise target value, the drainage time length is shortened, or the water outlet pressure value is reduced, or the spray arm action mode is adjusted. Therefore, by selecting to shorten the drainage time length when the noise detection value is greater than the noise target value, the noise of the dishwasher is reduced without reducing the cleaning effect.

[0090] In some possible embodiments, when the dishwasher determines that the noise detection value cannot be less than or equal to the noise target value by adjusting the parameters and the spray arm action after the water outlet pressure value is reduced and the spray arm action mode is adjusted for a first set number of times, the dishwasher selects to shorten the drainage time length, otherwise the drainage time length is not adjusted.

[0091] Therefore, by selecting to lengthen the washing time when the noise detection value is less than or equal to the noise target value and the cleaning effect detection value does not meet the target cleaning effect, the final cleaning effect of the dishwasher is enhanced without increasing the noise.

[0092] In the embodiment, the dishwasher has a tableware detection module for obtaining a tableware state; the dishwasher obtains the tableware state, and comprehensively determines the first washing action according to the tableware state, the noise target value and the target cleaning effect. The first washing action that meets the noise target value and the target cleaning effect is more easily determined, and the automatic test amount of the dishwasher is further reduced.

[0093] In some possible embodiments, the tableware state includes a tableware category, a tableware quantity and a tableware arrangement mode, and has a corresponding relationship with the first washing action. The first washing action initially performed by the dishwasher can be a combination of parameters of the first washing action corresponding to the noise target value, the target cleaning effect and the tableware state respectively, for example, the noise target value corresponds to the water outlet pressure value, the target cleaning effect corresponds to the rotation speed of the spraying arm, and the tableware state corresponds to the spraying arm action mode.

[0094] In other possible embodiments, the tableware state includes a tableware category, a tableware quantity and a tableware arrangement mode, and has a corresponding relationship with the first washing action. The noise target value, the target cleaning effect and the tableware state correspond to a first washing action respectively, and the first washing action initially performed by the dishwasher is a comprehensive value of the three first washing actions, for example, the comprehensive value is a maximum value, a minimum value, an average value or a weighted average value of the three parameters.

[0095] In the embodiment, as shown in Figure 2 The dishwasher noise control method specifically includes the following steps: a researcher inputs a noise target value and a target cleaning effect into the dishwasher through a computer or an application program of a mobile phone; a tableware detection module of the dishwasher obtains a tableware state; the dishwasher comprehensively determines a first washing action according to the tableware state, the noise target value and the target cleaning effect; the first washing action / second washing action is executed, the noise and the cleaning effect of the dishwasher are detected, noise detection values and cleaning effect detection values in a period of time are obtained, it is respectively judged whether the noise detection values are less than or equal to the noise target value and whether the cleaning effect detection values meet the target cleaning effect, the water outlet pressure value of the spraying arm and the spraying arm action mode of the washing action are adjusted according to whether both the two items are judged as no, the former is judged as no or the latter is judged as no, whether the drainage time is shortened is judged according to whether the number of times of adjustment exceeds a first set number of times, and whether the washing time is prolonged is judged according to whether the number of times of adjustment exceeds a second set number of times; when the cleaning effect detection values meet the target cleaning effect and the noise detection values are less than or equal to the noise target value at the same time, the current washing action is taken as an optimal washing action, and the washing is ended.

[0096] It can be understood that in some extreme embodiments, due to the selection of the water pump of the dishwasher and the motor driving the spray arm to rotate, there is a situation that cannot simultaneously satisfy the cleaning effect detection value meeting the target cleaning effect and the noise detection value being less than or equal to the noise target value. At this time, if the difference between the noise detection value and the noise target value is too large, the judgment of the noise is stopped, and the optimal washing action that the cleaning effect detection value just meets the target cleaning effect is obtained, and the washing is ended.

[0097] Further, when the dishwasher noise control method is loaded in the dishwasher as shown in Figures 3 to 5 The dishwasher is provided with a spray arm detection module for detecting the position of the spray arm 33. When the dishwasher starts to perform the first washing action or the second washing action, the position of the spray arm 33 is obtained and adjusted by the spray arm detection module to ensure that the spray arms 33 do not contact each other when rotating. The spray arm detection module can be an encoder provided at the motor driving the spray arm 33 to rotate, or an infrared sensor for detecting the distance between the spray arm 33 and the inner wall of the dishwasher.

[0098] In this embodiment: by the dishwasher, the washing action is automatically adjusted and improved according to the noise detection value and the cleaning effect detection value, and the optimal washing action is determined, realizing the automatic test of the dishwasher with the balance of cleaning effect and noise as the target, greatly reducing the amount of manual test of the research and development personnel, and accelerating the research and development process and the listing time of the dishwasher.

[0099] Embodiment two

[0100] As shown in Figures 1 to 5 This embodiment provides a dishwasher based on embodiment one, which performs the dishwasher noise control method described in embodiment one. The dishwasher comprises: a shelf 21 for placing tableware; and at least two independently horizontally rotating spray arms 33, wherein the at least two spray arms 33 are located on the same side of the shelf 21.

[0101] Preferably, the at least two spray arms 33 have overlapping regions towards the spray region of the shelf 21.

[0102] Therefore, by the dishwasher, better spraying effect is achieved by the at least two spray arms 33, and when the tableware is not full in the entire shelf 21, the water and time consumption caused by spraying the entire shelf 21 by a single spray arm is avoided.

[0103] In the embodiment, the four spray arms 33 are arranged below the shelf 21, the four spray arms 33 are arranged at the same horizontal level, and at least two spray arms 33 contact each other when the four spray arms 33 rotate simultaneously. The dishwasher comprises a spray arm detection module configured to detect the positions of the spray arms 33, and a control module communicatively connected to the spray arm detection module. The control module is configured to control the four spray arms 33 to not contact each other when the four spray arms 33 perform a plurality of combined spray arm modes according to the positions of the spray arms 33 detected by the spray arm detection module.

[0104] Therefore, the four spray arms 33 are closely arranged, and the space occupied by the four spray arms 33 is reduced.

[0105] In the embodiment, a noise detection module is configured to detect a noise detection value of the dishwasher, and a cleaning effect detection module is configured to detect a cleaning effect detection value of tableware in the shelf 21. A control module is communicatively connected to the noise detection module and the cleaning effect detection module, and is configured to determine whether to adjust the first washing action and determine an optimal washing action according to the noise detection value and the cleaning effect detection value.

[0106] The washing action in the embodiment includes the first washing action and the second washing action in Embodiment One, the noise detection value in the embodiment includes the first noise detection value and the second noise detection value in Embodiment One, and the cleaning effect detection value in the embodiment includes the first cleaning effect detection value and the second cleaning effect detection value in Embodiment One.
