FIG. 2 is a schematic view of a wash chamber divided into sub-areas of the dishwasher of the present invention.
Detailed Description
The first embodiment is as follows:
the invention provides a method for washing tableware by a dish washing machine, which comprises a water inlet component and a washing cavity, wherein the water inlet component is used for feeding water into the washing cavity, the bottom of the washing cavity is provided with a water collecting area for collecting washing water, a turbidity sensor is arranged in the water collecting area, as shown in figure 1, the method for washing tableware by the dish washing machine comprises a pre-washing stage S1 and a formal washing stage S2, in the pre-washing stage, the washing cavity is divided into a plurality of sub-areas, the water is fed into one sub-area for a certain time, the turbidity sensor is used for obtaining the turbidity of the washing water of the sub-area after the water feeding is started, then the turbidity of the washing water of the sub-area after the water feeding is finished is obtained, the turbidity difference of the sub-area is obtained by calculation, the turbidity difference of all the sub-areas is obtained in sequence, the dirt degree is judged according to the turbidity difference of each sub-area, the dish washing machine is provided with washing program parameters of each sub-area corresponding to the dirt degree, and then the formal washing stage is started to execute the washing program of each sub-area.
In brief, the sequential means that before the turbidity difference value of the previous sub-region is obtained, the turbidity difference value of the next sub-region is not obtained, that is, when water enters one sub-region in the pre-cleaning stage, water does not enter other sub-regions simultaneously. In the invention, water is fed into each subarea for a certain time in sequence in the pre-cleaning stage, and the turbidity data detected by the turbidity sensors in each water feeding time period is the subarea which is being pre-cleaned, so that only one turbidity sensor is arranged to obtain the turbidity difference values of all the subareas, the cost is obviously reduced, and meanwhile, in the process of obtaining the turbidity difference values of all the subareas, the method of feeding water into each subarea for a certain time in sequence is adopted, when the turbidity difference value of a certain subarea is obtained, other subareas cannot feed water, so that the real-time detection result of the turbidity sensors cannot be influenced by the dirt of other subareas, the detection accuracy of the turbidity sensors can be ensured, the method is more favorable for subsequently judging the dirt degree of tableware in each subarea, the method is naturally more favorable for accurately configuring cleaning program parameters, and the cleaning efficiency and the effect in the formal cleaning stage are improved. Because the turbidity difference of each subregion all obtains alone, therefore wash the chamber and separate how the subregion and all do not have the influence to turbidity sensor's testing result, the degree of freedom that the user put the tableware in washing the intracavity is higher, improves and uses experience.
In order to save the washing water, if the difference value of the turbidity of a certain subarea is smaller than the set value, the subarea is judged to have no tableware or the tableware is washed clean, and the subarea does not execute the washing program. Thus, the total time of the whole cleaning procedure can be shortened, and the cleaning efficiency is improved.
Because the dirt degrees of the tableware in all the sub-areas are not necessarily the same, the dirt degrees of some tableware are light, the required cleaning time is short, the dirt degrees of some tableware are heavy, and the required cleaning time is naturally long, therefore, in order to further save the cleaning water, the step of acquiring the turbidity difference values of the sub-areas again can be added after the cleaning program is executed for a certain time, if the turbidity difference value acquired again by a certain sub-area is smaller than the set value, the tableware in the sub-area is judged to be cleaned, the cleaning program is not executed any more, and if the turbidity difference value acquired again by a certain sub-area is larger than or equal to the set value, the cleaning program is continuously executed aiming at the sub-area. The object for acquiring the turbidity difference value again refers to a sub-area where the washing program has been executed, and if the washing program has not been executed from the beginning of a certain sub-area, the turbidity difference value does not need to be acquired again.
For controlling the sequential water inflow of each subarea, the water inflow assembly comprises a water inflow header pipe, a reversing valve and branch water paths which are arranged corresponding to each subarea, the water inflow header pipe is sequentially communicated with the branch water paths through the reversing valve to realize sequential water inflow to each subarea, and the cleaning procedures of each subarea are sequentially executed. In this case, the turbidity sensor can timely determine which sub-area has been cleaned according to the specific situation of the washing program executed by each sub-area, which is beneficial to saving water. Specifically, the sequence in which the cleaning program is started to be executed may be a random sequence, or the sequence may be from large to small, in which the cleaning program of each sub-region is sequentially executed, and if the turbidity difference values are equal, the cleaning program is randomly sequenced and executed for the sub-regions with the same turbidity difference values. For example, referring to the schematic diagram of the washing chamber shown in fig. 2, the dishes in A, B, C may be pre-washed sequentially to obtain the turbidity difference values of A, B, C in three sub-regions, and assuming that the sequence of the turbidity difference values of the three sub-regions from large to small is B, A, C, the washing procedure may be performed sequentially on B, A, C according to the sequence of the turbidity difference values, or the washing procedure may be performed sequentially on A, B, C still according to the sequence of the pre-washing stage, or may be randomly sequenced into C, B, A and then performed sequentially. If the difference between the turbidity values of A, B and two sub-regions is equal, the cleaning program can be selected to be executed on A first or B first.
Parameters influencing the aspects of cleaning efficiency, cleaning effect, water consumption and the like can be in a configured range, for example, parameters of a cleaning program can generally comprise at least one of water inlet pressure, water inlet time, water inlet temperature and detergent dosage, and the large direction is to improve the cleaning efficiency and the cleaning effect and reduce the water consumption.
The water outlet of the washing cavity is used as the existing structure of the dish-washing machine and can be directly utilized, so that the water collecting area can be selected as the water outlet of the washing cavity. It is of course also possible to provide a special sump in the washing chamber for detecting the turbidity of the washing water.
Because the mode of intaking in proper order is adopted, do not have the baffle between the different subregion and can not influence turbidity sensor's accurate detection yet, consequently subregion can select to form for virtual partition, need not set up the baffle promptly and separate, can confirm this subregion according to the actual condition of putting of tableware before wasing at every turn and divide the condition, and the degree of freedom is higher. The subareas can be divided by the user or automatically after being identified by photographing in a dishwasher. In order to improve the degree of freedom of sub-region division, more water inlets need to be distributed on the periphery of the cleaning cavity, and at least one water inlet is ensured in each sub-region.
When the user uses the dish washing machine, the tableware cannot be fully filled every time, so that the dish washing machine can be designed to comprise a human-computer interaction panel, and an input interface for the user to select to independently execute a cleaning program on a certain sub-region is arranged on the human-computer interaction panel. Therefore, the cleaning time can be shortened, the cleaning efficiency is improved, the water can be saved, and the use cost of a user is reduced. The input interface may be a touch screen, or may be a key, a knob, or the like.
Example two:
it can be understood that after the washing program is started, besides the mode of sequentially feeding water to each subarea, a mode of simultaneously feeding water can be adopted to shorten the whole washing time and improve the washing efficiency. When water needs to be fed into each subarea in sequence, the dishwasher can open each water inlet valve in sequence, and when water needs to be fed into the subarea executing the cleaning program at the same time, the dishwasher controls to open the corresponding water inlet valve, so that the dishwasher is convenient and simple to control.
Other contents not described in this embodiment may refer to embodiment one.
Example three:
in addition to the way of virtually separating the sub-regions, a way of physically separating the sub-regions may also be adopted, and in particular, a partition plate for separating the sub-regions is provided in the cleaning chamber. The partition board is preferably of a movable structure, and can be timely adjusted according to the condition of tableware to be cleaned each time.
Other contents not described in this embodiment may refer to embodiment one and embodiment two.
Other embodiments of the present invention than the preferred embodiments described above, and those skilled in the art can make various changes and modifications according to the present invention without departing from the spirit of the present invention, should fall within the scope of the present invention defined in the claims.
