Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
A method, apparatus, dishwasher, electronic device, and non-transitory computer readable storage medium for displaying a degree of washing in a washing process according to embodiments of the present invention are described below with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of an apparatus for displaying a cleaning degree in a cleaning process according to an embodiment of the present invention. As shown in fig. 1, the apparatus for displaying the degree of washing in a washing process comprises: a turbidity sensor 10, a controller 20 and a display 30.
Wherein the turbidity sensor 10 is arranged in the dishwasher sump, for example, at the bottom of the sump, at a central position of the sump bottom, or in a corner of the sump bottom, for example, at a water outlet of the sump bottom. The number of turbidity sensors 10 may be one or a plurality of turbidity sensors. In the case of a plurality of turbidity sensors 10, the feedback voltage of the washing water may be obtained by performing a comprehensive calculation based on the feedback voltage of each turbidity sensor 10. For example, an average value of the feedback voltages on all turbidity sensors 10 is calculated, and the average value is taken as the feedback voltage of the washing water.
In particular, turbidity is an optical property that characterizes a water sample and represents the degree of obstruction that suspended and colloidal materials in the water create when light passes through. When the pipeline passes through a certain amount of water, the amount of light penetration depends on the turbidity of the water. When the turbidity of the washing water is higher, less light penetrates through the water sample, and conversely, when the turbidity of the washing water is lower, more light penetrates through the washing water. The light receiving end converts the transmitted light intensity into corresponding current, the transmitted light is more, the current is more, and conversely, the transmitted light is less, and the current small current signal is converted into the current feedback voltage of the turbidity sensor through the resistor.
Further, the controller 20 may read a feedback voltage of the washing water from the turbidity sensor 10, and then may acquire a current turbidity level of the washing water according to the feedback voltage. In the embodiment of the present invention, as a possible implementation manner, a mapping relationship, for example, a mapping function, between the feedback voltage and the turbidity level may be established in advance. After the controller 20 obtains the feedback voltage, the feedback voltage may be input into the mapping relationship, to obtain the turbidity level matched with the feedback voltage.
As another possible implementation manner, a feedback voltage corresponding to the turbidity degrees of different washing waters obtained through experiments may be preset, and then a mapping list between the turbidity degrees and the feedback voltage is established. After the controller 20 acquires the feedback voltage, it may query the mapping list to obtain the turbidity level matched with the feedback voltage.
As another possible implementation manner, there may be a one-to-one correspondence between the feedback voltage and the turbidity level, or there may be a many-to-one relationship, that is, the feedback voltage in one interval may correspond to one turbidity level. And correspondingly establishing a plurality of feedback voltage intervals, wherein each interval corresponds to one turbidity degree, and after the feedback voltage is acquired, determining the interval in which the feedback voltage is positioned, thereby obtaining the corresponding turbidity degree.
It should be noted that, before calculating the turbidity level, since the turbidity sensor collects the analog voltage, the controller 20 also needs to sample the feedback voltage fed back by the turbidity sensor by using the analog-to-digital converter, and then obtains the current turbidity level of the washing water based on the possible implementation manner described above.
In practical application, when the user just put the tableware in dish washer, when dish washer begins to wash the tableware, because the tableware is dirty relatively, the washing water of drinking cup bottom is also relatively turbid this moment, and turbidity sensor detects the turbidity degree great, and after washing through first round, the turbidity degree that turbidity sensor detected water this moment when circulating washing after intaking again is compared beginning to have obviously become little, this indicates that the tableware is clean some. After water is re-fed for several times, the turbidity sensor detects that the water quality is gradually clean, and at the moment, the tableware becomes clean, and the cleaning degree is higher.
In the embodiment of the invention, the higher the turbidity degree of the washing water in the dish washer is, the lower the current washing degree of the tableware is, and the lower the turbidity degree of the washing water is, the higher the current washing degree of the tableware is. That is, the turbidity level of the washing water is inversely proportional to the washing level of the tableware, and there is a correspondence between the two. Further, after the controller 20 obtains the turbidity level of the washing water, the current washing level of the dishes may be obtained according to the correspondence relationship.
Further, after acquiring the current washing degree of the tableware, the controller 20 may acquire a display parameter matching the current washing degree and transmit the display parameter to the display 30. After receiving the display parameters, the display 30 displays the display parameters. Wherein the display parameter may be a percentage or a color saturation, or a number of display patterns, or numbers or letters. The setting form of the display parameters in the embodiment of the present invention is not limited herein. The degree of washing of the dishes can be displayed to the user in real time by displaying the parameters on the display.
In an embodiment of the present invention, as a possible implementation, the display 30 is provided on the dishwasher, so as to display the current degree of washing of the dishes on the dishwasher.
Optionally, the display 30 is a display on a terminal device associated with the dishwasher. The degree of washing of the dishwasher is displayed by means of a display 30 on the terminal device. Specifically, the controller 20 transmits the acquired display parameters to a terminal device associated with the dishwasher through a wireless network (WiFi, bluetooth, etc.), for example, a mobile phone, a wearable device, a personal computer, or the like. Upon receiving the display parameters, the terminal device may display the display parameters via its own display 30.
It should be noted that, connection needs to be established between the dish washer and the terminal device, the dish washer is provided with a wireless communication module, the dish washer is connected to a wireless network of a household through the wireless communication module, and then a wireless network connection can be established between the dish washer and a mobile phone or a computer in the household. After the wireless network connection is established, the display parameters can be displayed through a display interface of dishwasher control software installed on the mobile phone or the computer. By sending the display parameters to the terminal equipment for display, the washing degree of tableware in the dish washing machine can be known in real time even if a user does not need to be beside the dish washing machine any more.
It should be noted that the display 30 may comprise both a display provided on the dishwasher and a display on the associated terminal device.
In this embodiment, through the demonstration to the degree of washing of tableware in the dish washer to make the user can be accurate to knowing the degree of washing of tableware in the current dish washer, be favorable to promoting the intelligent control of dish washer, the user can improve the flexibility of user to dish washer operation to the understanding of dish washer working process moreover, thereby makes the dish washer be in under the efficient operating condition. The problem that when the dish washing machine works, a user does not know the washing condition of the dish washing machine and shuts down the dish washing machine to cause the dish not to be thoroughly cleaned is solved, the cleanliness degree of the user for washing the dish is ensured, and the user can use the dish washing machine to clean the dish more assuredly.
In order to ensure the cleanliness of the dish washing, it is required that the dishwasher can determine whether to extend the washing time of the dishwasher according to the current washing degree of the dishes. On the basis of the display of fig. 1, after the dish washer is controlled to display according to the display parameters, the washing time period of the dish washer can be controlled to be prolonged. As shown in fig. 2, the apparatus for displaying the cleaning degree in the cleaning process according to the embodiment of the present invention further includes: a timer 40 connected to the controller 20.
A timer 40 for acquiring a current remaining washing time period of the dishwasher. Optionally, the timer 40 obtains the total operation time required for the currently selected washing mode of the dishwasher, counts down from when the dishwasher is started to operate, and obtains the current remaining washing time of the dishwasher.
Wherein, the washing mode may include: strong washing, instant washing, soaking washing, energy-saving washing, etc. The total operating time period set for each washing mode is different, and the total operating time period can be preconfigured into the dishwasher or can be manually configured by a user according to the requirement.
As one possible implementation, the timer 40 counts from when the dishwasher starts to operate, acquires the operation duration of the dishwasher at the current time, and then transmits the operation duration to the controller 20. The controller 20 subtracts the operation time of the dishwasher at the current time from the total operation time of the currently selected washing mode of the dishwasher, thereby obtaining the current remaining washing time.
Further, the controller 20 determines a desired washing time period of the dishwasher according to the current turbidity level, and controls the dishwasher to extend the washing time period of the dishwasher if the desired washing time period is longer than the current remaining washing time period. The time for washing the dish washer is the rinsing time required by the current turbidity degree to clean the tableware, and the longer the turbidity degree is, the longer the time for washing the dish washer is, and the shorter the time for washing is otherwise.
In the embodiment of the invention, if the required washing time is longer than the current residual washing time, the dishwasher cannot completely wash the tableware in the current washing mode, and the dishwasher cannot be controlled to prolong the washing time because the tableware cannot be washed in the washing mode, and the dishwasher can obtain higher washing degree when the dishwasher finishes working by increasing the washing time.
Accordingly, if the required washing duration is less than or equal to the current remaining washing duration, which indicates that the dishwasher can completely wash the dishes in the current washing mode, the current washing mode can well work at the dirty degree of the dishes, and the current remaining washing duration is enough because the dishes can be washed in the washing mode, the dishwasher is not required to be controlled to extend the washing duration at the time, and the dishwasher can be controlled to continue to operate to the end in the washing mode to wash the dishes.
In order to reasonably extend the washing time of the dishwasher and minimize unnecessary energy consumption of the dishwasher, in an embodiment of the present invention, as one possible implementation: the controller 20 obtains a difference between the desired washing time period and the current remaining washing time period, obtains a ratio of the difference to the washing time period required for a single rinsing, and determines the number of rinsing times that the dishwasher needs to be increased according to the ratio.
The extension of the dishwasher washing time period is converted into the increase of the corresponding rinsing times, because the extension of the dishwasher washing time period is replaced by the increase of the rinsing times, there is a mapping relationship between the ratio of the extension time period to the washing time period required for the single rinsing and the increase of the rinsing times, the relationship is that the ratio of the ratio to the rinsing times is 1, i.e. the extension washing time period is equal to the total time period required for the extension rinsing times, and the possibility exists that the extension washing time period is smaller than the total time period required for the extension rinsing times. For example, when the ratio of the difference to the washing time required for a single rinsing is 3.5, which is not an integer, the number of rinsing cycles should be 4 in order to ensure that the dishes are washed.
As another possible implementation: the controller 20 determines whether the current operation stage of the dishwasher is the last rinsing stage. If the current operation stage is the last rinsing stage, the controller 20 acquires a preset turbidity level range corresponding to the last rinsing stage. And if the turbidity degree is larger than the upper limit value of the turbidity degree range, controlling to prolong the washing time of the dish-washing machine.
In general, in a certain washing mode of a dishwasher, a plurality of rinsing stages are often set, specifically, a current remaining washing time period of the dishwasher is compared with a washing time period required by a single rinsing, if the current remaining washing time period of the dishwasher is smaller than the washing time period required by the single rinsing, the current operation stage of the dishwasher is a final rinsing stage, and the controller 20 obtains a preset turbidity degree range corresponding to the final rinsing stage. If the current remaining washing time period of the dish washer is longer than the washing time period required by the single rinsing, the current running stage of the dish washer is not the last rinsing stage, the controller 20 returns to continuously judging whether the current running stage of the dish washer is the last rinsing stage or not, and the controller 20 obtains the preset turbidity degree range corresponding to the last rinsing stage until the current remaining washing time period of the dish washer is smaller than the washing time period required by the single rinsing.
Comparing the current turbidity degree with a preset turbidity degree range corresponding to the last rinsing stage, and determining the magnitude relation between the current turbidity degree and the turbidity degree range. If the turbidity level in the final rinsing stage is within the turbidity level range or less than the lower limit value of the turbidity level range, the tableware is in a washed state after the rinsing is finished, and if the upper limit value of the turbidity level range is exceeded, the cleanliness level of the tableware does not meet the washing standard after the rinsing is finished. That is, after the rinsing is finished, the dishes are not washed, and it is necessary to extend the washing time period of the dishwasher to ensure that the dishes are washed after the dishwasher stops washing.
Further, the control 20 obtains a ratio of the turbidity level to a central value of the turbidity level range, and determines the number of rinsing operations to be increased by the dishwasher according to the ratio. The mapping relation exists between the ratio of the turbidity degree to the central value of the turbidity degree range and the rinsing times to be increased, and the relation between the two to be preset of the dish-washing machine can be obtained in advance. For example, the ratio of the haze level to the center value of the haze level range is 2, and the number of rinsing times required to be increased is 6. At, for example, a ratio of the haze level to the center value of the haze level range of 3, the number of rinsing times required to be increased is 12. And determining that the rinsing times of the dish washing machine need to be increased according to a preset mapping relation between the two.
In the embodiment of the invention, in the washing process, when the washing degree is detected to be lower, the dish washer can be automatically controlled to prolong the washing time, so that tableware can be better washed, and the washing requirement of a user can be better met.
On the basis of fig. 2, as shown in fig. 3, the device for displaying the cleaning degree in the cleaning process further comprises: a reminder unit 50 and a detector 60.
The above-mentioned extension of the washing time length is to judge whether delay is needed according to the dish washing condition, if the judging result is that the washing time length needs to be prolonged, the reminding unit 50 sends the reminding information of the washing delay to the user, and the user can decide whether to prolong the washing time length by himself after receiving the reminding information sent by the dish washer. For example, a player may be provided on the gate, through which a voice alert is sent. For example, a gate status indicator light may be provided on the gate, and if the gate is in a closed state, the indicator light may be controlled to emit a red alert.
Further, the detector 60 detects an operation for extending the washing time period, and when the operation is currently detected, extends the washing time period according to the operation; wherein the operation includes a noncontact operation and a contact operation. The user prolongs the washing time through a certain operation, wherein the operation comprises a non-contact operation and a contact operation, the contact operation is that a delayed control button or a display interface is arranged on the dish washer, and the user can prolong the washing time by pressing the button or the display interface. The non-contact type dish washing machine is characterized in that a voice acquisition module is arranged on the dish washing machine, voice information of a user is acquired through the voice acquisition module, the acquired voice information is identified, and a command for prolonging the washing time is extracted.
Fig. 4 is a flow chart of a method for displaying the cleaning degree in the washing process according to an embodiment of the invention.
As shown in fig. 4, the method for displaying the degree of washing in the washing process includes the steps of:
step 401, detecting a current feedback voltage of a turbidity sensor in a washing process of a dish washer.
In the embodiment of the invention, taking a dish washer as an example, a turbidity sensor is arranged in the inner container of the dish washer, and the turbidity sensor can be used for detecting the turbidity condition of washing water in the washing process.
In particular, turbidity is an optical property that characterizes a water sample and represents the degree of obstruction that suspended and colloidal materials in the water create when light passes through. When the pipeline passes through a certain amount of water, the amount of light penetration depends on the turbidity of the water. When the turbidity of the washing water is higher, less light penetrates through the water sample, and conversely, when the turbidity of the washing water is lower, more light penetrates through the washing water. The light receiving end converts the transmitted light intensity into corresponding current, the transmitted light is more, the current is more, and conversely, the transmitted light is less, and the current small current signal is converted into the current feedback voltage of the turbidity sensor through the resistor.
Step 402, obtaining the current turbidity degree of the washing water according to the feedback voltage.
In the embodiment of the present invention, as a possible implementation manner, a mapping relationship between the feedback voltage and the turbidity level may be pre-established, for example, a mapping function may be used, and after the feedback voltage is obtained, the feedback voltage may be input into the mapping relationship to obtain the turbidity level matched with the feedback voltage. As another possible implementation manner, feedback voltages corresponding to the turbidity degrees of different washing waters obtained through experiments can be preset, then a mapping list between the turbidity degrees and the feedback voltages is established, and after the feedback voltages are obtained, the mapping list is queried to obtain the turbidity degrees matched with the feedback voltages.
As another possible implementation manner, there may be a one-to-one correspondence between the feedback voltage and the turbidity level, or there may be a many-to-one relationship, that is, the feedback voltage in one interval may correspond to one turbidity level. And correspondingly establishing a plurality of feedback voltage intervals, wherein each interval corresponds to one turbidity degree, and after the feedback voltage is acquired, determining the interval in which the feedback voltage is positioned, thereby obtaining the corresponding turbidity degree.
It should be noted that, before calculating the turbidity level, since the turbidity sensor collects the analog voltage, the feedback voltage fed back by the turbidity sensor is also needed to be sampled by the analog-digital converter, and then the current turbidity level of the washing water is obtained based on the possible implementation manner described above.
Step 403, determining the current washing degree of the tableware according to the current turbidity degree.
In practical application, when the dish washer is opened to wash the tableware just after putting the tableware in the dish washer, because the tableware is dirty, the washing water of drinking cup bottom is also relatively turbid this moment, and turbidity sensor detects the turbidity degree great, and after washing through first round, the turbidity degree that turbidity sensor detected water this moment when circulating the washing after intaking again is obviously reduced when beginning comparing, this indicates that the tableware is clean some. After water is re-fed for several times, the turbidity sensor detects that the water quality is gradually clean, and at the moment, the tableware becomes clean, and the cleaning degree is higher.
In the embodiment of the invention, the higher the turbidity degree of the washing water in the dish washer is, the lower the current washing degree of the tableware is, and the lower the turbidity degree of the washing water is, the higher the current washing degree of the tableware is. That is, the turbidity level of the washing water is inversely proportional to the washing level of the tableware, and there is a correspondence between the two. After the turbidity degree is obtained, the current washing degree of the tableware can be obtained according to the corresponding relation.
And step 404, acquiring display parameters matched with the current washing degree, and controlling the dish-washing machine to display according to the display parameters.
In the embodiment of the invention, as a possible implementation manner, the dish washer is provided with a display, and after the current washing degree is obtained, the display parameter can be obtained according to the washing degree. Wherein the display parameter may be a percentage or a color saturation, or a number of display patterns, or numbers or letters. The setting form of the display parameters in the embodiment of the present invention is not limited herein. The degree of washing of the dishes can be displayed to the user in real time by displaying the parameters on the display.
Optionally, the washing degree of the dishwasher may be displayed through a display screen of the terminal device, specifically, the dishwasher is controlled to send the obtained display parameters to the terminal device associated with the dishwasher through a wireless network (WiFi, bluetooth, etc.), for example, a mobile phone, a wearable device, a personal computer, etc. The terminal device can display according to the display parameters after receiving the display parameters. It should be noted that, connection needs to be established between the dish washer and the terminal device, the dish washer is provided with a wireless communication module, the dish washer is connected to a wireless network of a household through the wireless communication module, and then a wireless network connection can be established between the dish washer and a mobile phone or a computer in the household. After the wireless network connection is established, the display parameters can be displayed through a display interface of dishwasher control software installed on the mobile phone or the computer. By sending the display parameters to the terminal equipment for display, the washing degree of tableware in the dish washing machine can be known in real time even if a user does not need to be beside the dish washing machine any more.
In this embodiment, through the demonstration to the degree of washing of tableware in the dish washer to make the user can accurately know the degree of washing of the interior tableware of current dish washer, be favorable to promoting the intelligent control of dish washer, the user can improve the flexibility of user to dish washer operation to the understanding of dish washer working process moreover, thereby makes the dish washer be in under the efficient operating condition. The problem that when the dish washing machine works, a user does not know the washing condition of the dish washing machine and shuts down the dish washing machine to cause the dish not to be thoroughly cleaned is solved, the cleanliness degree of the user for washing the dish is ensured, and the user can use the dish washing machine to clean the dish more assuredly.
In order to ensure the cleanliness of the dish washing, it is required that the dishwasher can determine whether to extend the washing time of the dishwasher according to the current washing degree of the dishes. On the basis of the display of fig. 4, after the dish washer is controlled to display according to the display parameters, the washing time period of the dish washer can be controlled to be prolonged. As shown in fig. 5, the embodiment of the invention provides a method for judging whether to control a dishwasher to prolong washing time, which specifically comprises the following steps:
step 501, determining a washing time period required by the dish washer according to the current turbidity degree.
The time for washing the dish washer is the rinsing time required by the current turbidity degree to clean the tableware, and the longer the turbidity degree is, the longer the time for washing the dish washer is, and the shorter the time for washing is otherwise.
Step 502, obtaining the current residual washing time of the dish washer.
And counting time from the beginning of the operation of the dish washing machine, obtaining the operation time of the dish washing machine at the current time, and subtracting the operation time of the dish washing machine at the current time from the total operation time of the currently selected washing mode of the dish washing machine to obtain the current residual washing time. The washing mode may include: strong washing, instant washing, soaking washing, energy-saving washing, etc. The total operating time period set for each washing mode is different, and the total operating time period can be preconfigured into the dishwasher or can be manually configured by a user according to the requirement.
If the required washing time period is longer than the current remaining washing time period, the dishwasher is controlled to extend the washing time period of the dishwasher, step 503.
In the embodiment of the invention, if the required washing time is longer than the current residual washing time, the dishwasher cannot completely wash the tableware in the current washing mode, and the dishwasher cannot be controlled to prolong the washing time because the tableware cannot be washed in the washing mode, and the dishwasher can obtain higher washing degree when the dishwasher finishes working by increasing the washing time.
Accordingly, if the required washing duration is less than or equal to the current remaining washing duration, which indicates that the dishwasher can completely wash the dishes in the current washing mode, the current washing mode can well work at the dirty degree of the dishes, and the current remaining washing duration is enough because the dishes can be washed in the washing mode, the dishwasher is not required to be controlled to extend the washing duration at the time, and the dishwasher can be controlled to continue to operate to the end in the washing mode to wash the dishes.
In order to reasonably extend the washing time of the dishwasher and minimize unnecessary energy loss of the dishwasher, an embodiment of the present invention provides a method for extending the washing time of the dishwasher, as shown in fig. 6, which specifically includes the following steps:
step 601, obtaining a difference value between the required washing time length and the current remaining washing time length.
Step 602, obtaining a ratio of the difference value to a washing time period required by single rinsing.
Step 603, determining the number of rinsing times the dishwasher needs to be increased according to the ratio.
The extension of the dishwasher washing time period is converted into the increase of the corresponding rinsing times, because the extension of the dishwasher washing time period is replaced by the increase of the rinsing times, there is a mapping relationship between the ratio of the extension time period to the washing time period required for the single rinsing and the increase of the rinsing times, the relationship is that the ratio of the ratio to the rinsing times is 1, i.e. the extension washing time period is equal to the total time period required for the extension rinsing times, and the possibility exists that the extension washing time period is smaller than the total time period required for the extension rinsing times. For example, when the ratio of the difference to the washing time required for a single rinsing is 3.5, which is not an integer, the number of rinsing cycles should be 4 in order to ensure that the dishes are washed.
As shown in fig. 7, another method for determining whether to control a dishwasher to extend a washing time period according to an embodiment of the present invention includes the following steps:
step 701, determining whether the current operation phase of the dishwasher is the last rinsing phase.
In general, in a certain washing mode, a plurality of rinsing stages are often set in the dishwasher, specifically, the current remaining washing duration of the dishwasher is compared with the washing duration required by a single rinsing, if the current remaining washing duration of the dishwasher is smaller than the washing duration required by a single rinsing, the current running stage of the dishwasher is the last rinsing stage, and the following step 702 is directly executed; if the current remaining washing time period of the dish washer is longer than the washing time period required by the single rinsing, the current operation stage of the dish washer is not the last rinsing stage, and the judging process of the step 701 is continuously executed until the current remaining washing time period of the dish washer is smaller than the washing time period required by the single rinsing, and the step 702 is executed.
Step 702, if the current operation stage is the last rinsing stage, obtaining a preset turbidity degree range corresponding to the last rinsing stage.
And step 703, if the turbidity degree is greater than the upper limit value of the turbidity degree range, controlling to prolong the washing time of the dish washer.
Comparing the current turbidity degree with a preset turbidity degree range corresponding to the last rinsing stage, and determining the magnitude relation between the current turbidity degree and the turbidity degree range. If the turbidity level in the final rinsing stage is within the turbidity level range or less than the lower limit value of the turbidity level range, the tableware is in a washed state after the rinsing is finished, and if the upper limit value of the turbidity level range is exceeded, the cleanliness level of the tableware does not meet the washing standard after the rinsing is finished. That is, after the rinsing is finished, the dishes are not washed, and it is necessary to extend the washing time period of the dishwasher to ensure that the dishes are washed after the dishwasher stops washing.
As shown in fig. 8, an embodiment of the present invention provides another method for extending a washing time period of a dishwasher, which specifically includes the steps of:
step 801, obtaining a ratio of the turbidity degree to a central value of the turbidity degree range.
Step 802, determining the number of rinses that the dishwasher needs to increase based on the ratio.
The mapping relation exists between the ratio of the turbidity degree to the central value of the turbidity degree range and the rinsing times to be increased, and the relation between the two to be preset of the dish-washing machine can be obtained in advance. For example, the ratio of the haze level to the center value of the haze level range is 2, and the number of rinsing times required to be increased is 6. At, for example, a ratio of the haze level to the center value of the haze level range of 3, the number of rinsing times required to be increased is 12. And determining that the rinsing times of the dish washing machine need to be increased according to a preset mapping relation between the two.
The extension of the washing time length is that the dish washer judges whether delay is needed according to the dish washing condition, if the judging result is that the washing time length is needed to be prolonged, the dish washer sends reminding information of the washing delay to a user, and the user can determine whether to prolong the washing time length by himself after receiving the reminding information sent by the dish washer. For example, a player may be provided on the gate, through which a voice alert is sent. For example, a gate status indicator light may be provided on the gate, and if the gate is in a closed state, the indicator light may be controlled to emit a red alert.
The washing time is prolonged by a user through a certain operation, wherein the operation comprises a non-contact operation and a contact operation, the contact operation is that a delayed control button or a display screen is arranged on the dish washer, and the user can prolong the washing time by pressing the button or the display screen. The non-contact type dish washing machine is characterized in that a voice acquisition module is arranged on the dish washing machine, voice information of a user is acquired through the voice acquisition module, the acquired voice information is identified, and a command for prolonging the washing time is extracted.
In the embodiment of the invention, in the washing process, when the washing degree is detected to be lower, the dish washer can be automatically controlled to prolong the washing time, so that tableware can be better washed, and the washing requirement of a user can be better met.
