In order to solve the problem that the existing dish washing machine is long in washing time, the dish washing machine is in communication connection with the cloud server, the cloud server is in communication connection with the water heater, the dish washing machine is provided with a first water inlet, the first water inlet is provided with a first water inlet valve, the water heater is provided with a water heater water outlet, the first water inlet is communicated with the water heater water outlet, the dish washing machine is further provided with a second water inlet, the second water inlet is provided with a second water inlet valve, the second water inlet is communicated with a tap water outlet, the dish washing machine is further provided with a water outlet, the water outlet is provided with a water drain valve, and the dish washing machine is further provided with a heating module. That is, when the first water inlet valve is opened, water enters the dishwasher from the water outlet of the water heater through the first water inlet so as to realize that the water heater supplies water for the dishwasher, and when the second water inlet valve is opened, namely, water enters the dishwasher from the tap water outlet through the second water inlet so as to realize that tap water is injected into the dishwasher; it is to be understood that although the present invention has been described with reference to the first and second inlet valves and the first and second inlets, it does not mean that two control valves or two inlets are necessarily provided in the present invention, the first inlet valve and the second inlet valve may be combined into one control valve, for example, a three-way valve with two inlets and one outlet, and further, the first inlet and the second inlet may be combined into one inlet. In addition, the arrangement position of the heating module on the dishwasher is not limited, as long as the water in the dishwasher can be heated, for example, the heating module can be arranged in the inner container of the dishwasher; alternatively, if the dishwasher is provided with a water reservoir (for supplying the dishwasher with hot water), the heating module may also be provided on the water reservoir in this case.
As shown in fig. 1, the control method of the dishwasher of the present invention includes the steps of:
step S101: and receiving a washing program reserving instruction, and acquiring a washing water reserving temperature and a washing reserving time.
The receiving mode of the dish washing machine for receiving the reserved washing program instruction comprises multiple modes, for example, the receiving mode can be received after a user presses a key of the dish washing machine, the receiving mode can be received after the user selects the reserved program through an intelligent terminal APP, and the like; the reserved washing time can be manually set by a user, or the dishwasher can be executed by default based on the common reserved habit of the user.
Step S102: whether high-temperature washing is required is judged based on the reserved washing water temperature.
Among them, the way of judging whether high temperature washing is needed includes various ways based on the preset washing water temperature. For example, a set temperature threshold value at which the dishwasher requires high-temperature washing may be set in advance, and the determination result may be "required" when the preset washing water temperature is equal to or higher than the set temperature threshold value, and the determination result may be "unnecessary" when the preset washing water temperature is lower than the set temperature threshold value, for example, the set temperature threshold value is 50 ℃ (usually higher than the temperature of tap water), the preset washing water temperature is 60 ℃, and high-temperature washing is required. Or, the preset washing water temperature and the current temperature of the tap water may be compared, when the preset washing water temperature is higher than the current temperature of the tap water, the judgment result is "required", and when the preset washing water temperature is lower than or equal to the current temperature of the tap water, the judgment result is "unnecessary", wherein the temperature of the tap water may be obtained through a temperature sensor or through detection of other intelligent household appliances.
Step S103: and when the judgment result is 'needed', sending the reserved washing water temperature and the reserved washing time to the cloud server so that the cloud server sends the reserved washing water temperature and the reserved washing time to the water heater, and the water in the water heater is heated to the reserved washing water temperature by the water heater before the reserved washing time is reached.
Step S104: and when the preset washing time is reached, controlling the first water inlet mode to start.
Wherein the first water intake mode includes: controlling a first water inlet valve to be opened so that the water heater supplies water to the dish washing machine; and when the water with the preset water quantity is injected, controlling the first water inlet valve to be closed. That is, the first water inlet mode is to supply water to the dishwasher through the water heater. In addition, it can be understood that the preset water amount value may be obtained from a reserved washing program, or may be obtained by a user through setting, and the like, and the determination method of whether the water in the dishwasher reaches the preset water amount includes various manners, for example, the determination method may be performed by setting a water level sensor in the dishwasher, that is, when the water level value corresponding to the preset water amount is reached, it is determined that the dishwasher has injected the water of the preset water amount, and at this time, the first water inlet valve is controlled to be closed; alternatively, the water flow rate may be directly measured by a method such as providing a flowmeter on the first water inlet valve. The above-mentioned judging and obtaining method of the water with the preset water amount is the same as the principle of the judging and obtaining method of the water with the preset water amount mentioned in the following of the present invention, and will not be described in detail below.
Step S105: and after the first water inlet mode operation is finished, operating a reserved washing program.
The setting mode has the advantages that: when the dish washer needs to carry out high temperature washing, the water heater has heated water to reservation washing temperature before the reservation time arrives to make the dish washer can directly use the hot water in the water heater when the washing begins, need not to use heating module to heat water, thereby can very big reduction washing time, improve washing efficiency, and can reduce use cost.
In addition, the judgment result is 'unnecessary', and when the preset washing time is reached, the second water inlet mode is controlled to be started; after the second water inlet mode operation is finished, operating a washing appointment program; wherein the second water intake mode includes: controlling the second water inlet valve to be opened; and when the water with the preset water quantity is injected, controlling the second water inlet valve to be closed.
When the user does not need to wash at high temperature, the dishwasher is supplied with water through the second water inlet mode, that is, the dishwasher directly injects tap water of a preset water amount. Through the setting of the second water inlet mode, the situation that hot water is used in a water heater to cause waste of heat energy or damage to washed articles can be avoided.
In a word, above-mentioned mode of setting up makes dish washer can be according to the washing needs, and the corresponding mode of intaking of operation makes dish washer more intelligent, under the condition of assurance washing effect that can be abundant, has avoided the waste of the energy, has practiced thrift the washing time, has improved the washing effect.
The first and second water inlet modes mentioned hereinafter are the same as the control modes included in the first and second water inlet modes mentioned above, and will not be described in detail hereinafter.
As shown in fig. 2, as a possible embodiment, the control method of the dishwasher of the present invention further includes the following steps.
Step S201: and receiving an instant washing program instruction and acquiring the instant washing water temperature.
The receiving mode of the dishwasher for receiving the instant washing program instruction includes multiple modes, for example, the receiving mode can be received after a user presses a key of the dishwasher, or the receiving mode can be received after the user selects the instant washing program through the intelligent terminal APP, and in addition, the mode of the instant washing water temperature acquired by the dishwasher also includes multiple situations, for example, the instant washing water temperature can be acquired through the instant washing program, and can also be set by the user.
Step S202: whether high-temperature washing is required is judged based on the instant washing water temperature.
Among them, the manner of judging whether high temperature washing is needed includes various manners based on the washing water temperature. For example, a set temperature threshold value at which the dishwasher requires high-temperature washing may be set in advance, and the determination result may be "required" when the instantaneous washing water temperature is equal to or higher than the set temperature threshold value, and the determination result may be "unnecessary" when the instantaneous washing water temperature is lower than the set temperature threshold value, for example, the set temperature threshold value is 50 ℃ (usually higher than the temperature of tap water), that is, the washing water temperature is 60 ℃, and high-temperature washing is required. Or, the instant washing water temperature and the current temperature of the tap water can be compared, when the instant washing water temperature is higher than the current temperature of the tap water, the judgment result is 'needed', and when the instant washing water temperature is lower than or equal to the current temperature of the tap water, the judgment result is 'not needed', wherein the temperature of the tap water can be obtained through a temperature sensor or through detection of other intelligent household appliances.
Step S203: and when the judgment result is 'needed', sending the washing water temperature to the cloud server so that the cloud server judges the range of the current water temperature after acquiring the current water temperature of the water heater.
Specifically, the current water temperature may be compared with only the instant washing water temperature, and may be further compared with a preset first water temperature, wherein the instant washing water temperature is greater than the preset first water temperature, for example, the instant washing water temperature is 72 ℃, and the preset first water temperature is 40 ℃. In general, the washing water temperature is the temperature at which the washing effect is best when the dishwasher is running, i.e. the washing program; and the washing effect of the dishwasher is deteriorated if the temperature below the first water temperature is preset.
Step S204: and receiving a judgment result.
As a possible implementation, the determination result includes: judging a first result: the current water temperature is more than or equal to the washing water temperature; and a second judgment result: the current water temperature is less than the washing water temperature; the judgment result II can be further subdivided into a judgment result III and a judgment result IV, wherein the judgment result III is as follows: the current water temperature is less than the washing water temperature and more than or equal to a preset first water temperature; the fourth judgment result is: the current water temperature is less than a preset first water temperature.
Step S205: and selectively controlling the first water inlet mode or the second water inlet mode to be started based on the judgment result.
Firstly, when the current water temperature is larger than or equal to the washing water temperature (judgment result I), the first water inlet mode is controlled to be started. Under the condition, the temperature of the hot water in the water heater can meet the washing temperature requirement of the dish-washing machine, the dish-washing machine can achieve the best washing effect, at the moment, the water heater directly supplies the hot water for the dish-washing machine, in addition, the dish-washing machine does not need to heat the water in the arrangement mode, the washing time can be shortened, and the use cost is reduced.
And secondly, when the current water temperature is less than the washing water temperature and is more than or equal to the preset first water temperature (a third judgment result), controlling the first water inlet mode to start. Although the water temperature in the water heater does not reach the temperature which can enable the dishwasher to achieve the best washing effect, because the current water temperature is higher than the preset first water temperature, the preset first water temperature is higher than the temperature of the tap water in the normal condition, for example, the preset first water temperature is 40 ℃, the temperature of the tap water is 20 ℃, in this case, the effect of dissolving the stains by the water with the temperature higher than 40 ℃ is better than the effect of dissolving the stains by the water with the temperature of 20 ℃, in this case, the first water inlet mode is better than the washing effect of the second water inlet mode, and therefore, the arrangement mode can improve the washing effect.
Further, after the first water inlet mode operation is finished, the heating module is controlled to heat the water to the washing water temperature. The arrangement mode can enable the washing effect of the dish washing machine to be optimal, and compared with a mode of directly introducing tap water into the dish washing machine and heating the tap water, the water temperature in the water heater is higher than that of the tap water, so that the arrangement mode can shorten the heating time of the heating module of the dish washing machine, the time consumption of the whole washing program is reduced, and the electric energy of the dish washing machine is saved.
And thirdly, when the current water temperature is lower than the preset first water temperature (the judgment result is four), controlling the second water inlet mode to start. In this case, the temperature of the water heater is generally low, for example, the water heater is not in the heating mode when the water heater is turned on, and at this time, since the pipe connecting the dishwasher and the tap water pipe is generally short and the water inlet is more convenient, the second water inlet mode is controlled to be activated to introduce the tap water into the dishwasher.
Further, after the second water inlet mode operation is finished, the heating module is controlled to heat the water to the washing water temperature. The arrangement mode can enable the water temperature in the dish washing machine to rise to the washing water temperature with the best washing effect, namely washing water temperature, thereby improving the washing efficiency.
Further, as a preferred embodiment, when the current water temperature is lower than the instant washing water temperature (determination result two), the instant washing water temperature is sent to the cloud server, so that the cloud server issues the instant washing water temperature to the water heater, and the water heater heats the water to the instant washing water temperature. According to the arrangement mode, the water heater can immediately heat water, meanwhile, the dish washing machine starts the first water inlet mode or the second water inlet mode, when the water heater heats the water to the temperature of the instant washing water, hot water can be provided for the subsequent washing process, for example, when the dish washing machine reaches a water injection condition, the washing efficiency of the dish washing machine can be improved and the washing time can be shortened through injecting the hot water into the water heater.
Step S206: and after the first water inlet mode or the second water inlet mode is operated, the washing program is operated.
When the user does not need to wash at high temperature, the dishwasher is supplied with water through the second water inlet mode, that is, the dishwasher directly injects tap water of a preset water amount. Through the setting of the second water inlet mode, the situation that hot water in the water heater is introduced under the condition that the hot water is not needed to be used can be avoided, and the waste of heat energy or the damage to washed articles are caused.
As shown in fig. 3, as a possible embodiment, the control method of the dishwasher further includes the following steps.
Step S301: in the washing process, the temperature of the washing water is obtained.
Wherein, the mode of obtaining the washing water temperature in the dish washer includes the multiple: for example, by a temperature sensor provided on the dishwasher, or by an infrared thermometer or the like.
Step S302: and judging the water temperature of the washing water and the preset first water temperature.
Step S303: when the water temperature of the washing water is smaller than a preset first water temperature, sending an instruction for inquiring the current water temperature of the water heater to the cloud server so that the server can judge the range of the current water temperature of the water heater.
When the water temperature of the washing water is smaller than the preset first water temperature, the fact that the washing effect of the dishwasher is deteriorated is proved, and the range where the current water temperature of the water heater is located is judged through the server, so that whether the dishwasher can use the hot water in the water heater or not can be known.
Specifically, the current water temperature may be compared only with the immediate washing water temperature or the scheduled washing water temperature, and may be further compared with the preset first water temperature, wherein the immediate washing water temperature is greater than the preset first water temperature, for example, the immediate washing water temperature or the scheduled washing water temperature is 72 ℃, and the preset first water temperature is 40 ℃. In general, the washing water temperature or the reserved washing water temperature is the temperature at which the washing effect is optimal when the dishwasher is operated, i.e., the washing program or the reserved washing program; the washing effect of the dishwasher is deteriorated by presetting the temperature below the first water temperature.
Step S304: and receiving a judgment result.
As a possible implementation, the determination result includes:
the first judgment result is: the current water temperature is more than or equal to a preset first water temperature; the first judgment result can be subdivided into a second judgment result and a third judgment result, wherein the second judgment result is as follows: the current water temperature is more than or equal to the washing water temperature or the appointed washing water temperature; the third judgment result is: the current water temperature is more than or equal to the preset first water temperature and is less than the instant washing water temperature or the reserved washing water temperature. The fourth judgment result is: the current water temperature is less than a preset first water temperature.
It can be understood that the judgment of the cloud server on the range of the current water temperature of the water heater may be continuous judgment, or may be judgment after a preset time interval, for example, judgment is performed once at an interval of 5 s.
Step S305: and selectively controlling the drain valve to be immediately opened or to be opened again when the temperature of the washing water is less than a preset second water temperature, based on the determination result.
Specifically, when the current water temperature is greater than or equal to a preset first water temperature (a first judgment result), the drain valve is controlled to be opened immediately, and when the washing water is drained, the drain valve is controlled to be closed, and the first water inlet mode is controlled to be started. At this time, since the temperature of the hot water in the water heater is high, the dishwasher discharges the washing water in the dishwasher in order to introduce the hot water in the water heater, thereby avoiding mixing the washing water with low temperature, lowering the temperature of the mixed water as a whole, and further influencing the washing effect.
Further, when the current water temperature is greater than or equal to the preset first water temperature and is less than the immediate washing water temperature or the reserved washing water temperature (a third judgment result), after the first water inlet mode operation is finished, the heating module is controlled to heat the water to the immediate washing water temperature or the reserved washing water temperature. Because the hot water introduced into the water heater has a certain water temperature (higher than that of the washing water), at the moment, the dishwasher can heat the water to the washing water temperature or the reserved washing water temperature in a short time by heating the heating module, thereby meeting the requirements of washing effects and shortening the washing time. For example, if the temperature of the washing water or the scheduled washing water is 72 ℃, the current water temperature is 60 ℃, and the temperature of the drained washing water is 35 ℃, the temperature is increased from 60 ℃ to 72 ℃ and the heating time is much shorter than the heating time from 35 ℃ to 72 ℃.
In addition, when the current water temperature is greater than or equal to the instant washing water temperature or the reserved washing water temperature (second judgment result), after the first water inlet mode operation is finished, since the hot water introduced from the water heater meets the washing temperature requirement, the water is not required to be heated through the heating module, and the water is directly washed, so that the energy can be saved and the washing time can be further shortened under the condition of achieving the optimal washing effect.
In addition, when the current water temperature is lower than the preset first water temperature (fourth judgment result), the drain valve is controlled to be opened again when the water temperature of the washing water is lower than the preset second water temperature, and when the washing water is drained, the drain valve is controlled to be closed; controlling the second water inlet mode to start; and after the second water inlet mode is finished, controlling the heating module to heat the water to the instant washing water temperature or the reserved washing water temperature.
Wherein, the dishwasher washes under the condition of the preset second water temperature (for example, 25 ℃) or lower, and the washing effect of the dishwasher is the worst.
Specifically, when the current water temperature of the water heater is less than the preset first water temperature, at this time, the temperature of water in the water heater is already low, and therefore, water in the water heater does not need to be introduced, so that the increase of the washing time is caused, the dishwasher continues to perform washing (the washing water temperature is less than the preset first water temperature and is more than or equal to the preset second water temperature), through the increase of the washing time, a good washing effect is finally achieved, until the washing water temperature is less than the preset second water temperature, at this time, the washing effect is very poor, an ideal washing effect is hardly achieved through the extension time, and because the washing water at this time has been subjected to washing for a period of time, the washing water is already dirty, under such a condition, the washing water in the dishwasher is drained, tap water is introduced again to heat, so that a good washing effect is achieved.
In conclusion, the invention can avoid or greatly reduce the process of heating water temperature under the condition of ensuring the washing effect by the linkage mode of the dish washer and the water heater during the scheduled washing and the instant washing, thereby reducing the washing time of the dish washer.
