[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0030] The dishwasher uses a washing pump to make water flow and remove heat from the heater. Therefore, the faster the water flow rate, that is, the higher the rotation speed, the faster the heating speed. Since scale adheres to the inner cavity of the dishwasher, it indirectly causes scale to adhere to the surface of the heater. The more scale there is, the longer it takes to heat to the target temperature, affecting the user experience and washing effect.

[0031] According to an embodiment of the present invention, an embodiment of a method for cleaning scale from equipment is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0032] In this embodiment, a method for cleaning scale on equipment is provided, which can be used in the above-mentioned controller, wherein the equipment includes a washing device. The specific structure and model of the washing device are not limited, and the corresponding washing device can be determined according to actual equipment requirements. For example, the washing device installed in the dishwasher is a washing pump, which is only used as an example. Figure 1 Flowchart of a method for cleaning scale of equipment according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0033] Step S101 , in response to the device entering a cleaning mode, the device is controlled to perform a water intake operation, and after the device completes the water intake, the water temperature is heated.

[0034] In response to the user setting the device to run the self-cleaning washing mode, the embodiment of the present invention can first enter the pre-wash stage, control the device to perform the water intake operation, and after the device completes the water intake, the water temperature can be heated by the heating device in the device, just as an example.

[0035] Step S102: Control the washing device to operate and record the current heating time required when the water temperature is heated from the first temperature to the second temperature.

[0036] Among them, the operating speed of the washing device is positively correlated with the water temperature.

[0037] The embodiment of the present invention can control the washing device to operate at a corresponding operating speed according to the water temperature in the current equipment to realize the flow of water. Because the washing device can effectively help the heat generated by the heating device to be taken away during the washing process by accelerating the water flow speed, the overall law of the operating speed of the washing device and the water temperature is generally positively correlated. Different water temperature intervals can be set to correspond to different operating speeds. Generally, different water temperature intervals are set to correspond to different operating speeds based on actual operating conditions. Among them, the water temperature interval interval can be set according to the sampling time interval and the actual setting situation. The interval corresponding to the operating speed can also be set to ensure the washing effect. For example, the water temperature is sampled at 5°C. Considering the washing effect, the operating speed of the washing device can be set to an interval of 500 rpm. In the water temperature range of 5-10℃, the corresponding operating speed is 1000 rpm, the water temperature range of 10-15℃ corresponds to an operating speed of 1500 rpm, and the water temperature range of 15-20℃ corresponds to an operating speed of 2000 rpm. This is just an example. There is no limitation on the reference form of the positive correlation between water temperature and the operating speed of the washing device. For example, a relationship line graph is used to represent the positive correlation between the operating speed of the washing device and the water temperature. This is just an example. The operating speed of the washing device can be adjusted by referring to the relationship curve between the operating speed of the washing device and the water temperature and the current water temperature of the equipment in real time.

[0038] When the embodiment of the present invention controls the washing device to operate at a corresponding operating speed, the current time required for the water temperature of the device to be heated from a first temperature to a second temperature can be recorded, wherein the first temperature and the second temperature are not limited, and can be within the water temperature range when the device is operating normally. The second temperature is greater than the first temperature. Generally, since heat dissipation is faster when the water temperature is higher, the temperature rise is also faster in the low temperature range. Therefore, a temperature heating range of 20°C to 40°C can be set, and the speed of the influencing factor is changed within this range to determine the temperature rise rate. This is only an example.

[0039] Step S103: determining the current scale level of the equipment based on the current required heating time.

[0040] In an embodiment of the present invention, multiple experiments may be conducted in advance based on the current equipment model, or technical personnel may determine the heating time required for temperature rise corresponding to different scale levels based on the equipment model and human experience. The more scale there is, the longer it takes to heat to the target temperature. For example, a first time threshold corresponding to when there is no scale, a second time threshold when the scale level is low, and a third time threshold when the scale level is high is set. Among them, the first time threshold is smaller than the second time threshold and smaller than the third time threshold. The scale level of the current equipment is determined by comparing the current required heating time with these three time thresholds. This is only an example.

[0041] Step S104: performing corresponding scale cleaning operations based on the current scale level of the equipment.

[0042] In the embodiment of the present invention, different scale cleaning operations are performed corresponding to different scale levels of the equipment. The corresponding amount of descaling agent can be automatically added according to the scale level. For example, if there is no scale, there is no need to add descaling agent. The higher the scale level, the more descaling agent is added. As an example only, the scale cleaning operation of the equipment is performed to fully dissolve the scale.

[0043] The device scale cleaning method provided in this embodiment controls the device to perform a water intake operation in response to the device entering a cleaning mode, and heats the water temperature after the device completes the water intake, records the current heating time required for the water temperature to be heated from a first temperature to a second temperature, determines the current device scale level based on the current required heating time, and performs a corresponding scale cleaning operation based on the current device scale level. The scale of the device can be cleaned in a timely manner, thereby improving user experience and washing effects, and reducing the probability of damage to the heater and washing pump.

[0044] In this embodiment, a device scale cleaning method is provided, which can be used in the above-mentioned controller. Figure 2 Flowchart of a method for cleaning scale of equipment according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0045] Step S201: In response to the device entering the cleaning mode, the device is controlled to perform a water intake operation, and after the device completes the water intake, the water temperature is heated. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0046] Step S202: Control the washing device to operate and record the current heating time required when the water temperature is heated from the first temperature to the second temperature.

[0047] Among them, the operating speed of the washing device is positively correlated with the water temperature.

[0048] Specifically, the above step S202 includes:

[0049] Step S2021: Divide all temperatures between the first temperature and the second temperature into a preset number of temperature intervals.

[0050] Step S2022: Control the washing device to operate at different operating speeds in different temperature intervals, and record the time required for the temperature rise in each temperature interval.

[0051] Step S2023: summing the time required for temperature rise in all temperature intervals to obtain the current required heating time when the water temperature is heated from the first temperature to the second temperature.

[0052] The device of the embodiment of the present invention uses the washing device to realize the flow of water to remove the heat generated by the heater. Therefore, the faster the water flow speed is, the higher the speed is, the faster the heating speed is. By studying the time relationship between the washing device running at multiple speeds and the temperature rise, the degree of scale is confirmed, making the detection of the degree of scale more accurate. Figure 3 As shown, the time t4 required for heating from 20°C to 40°C at an operating speed of 2000r / min can be represented by a half line, the time t3 required for heating from 20°C to 40°C at an operating speed of 2500r / min can be represented by a dot, the time t2 required for heating from 20°C to 40°C at an operating speed of 3000r / min can be represented by a double line, and the time t1 required for heating from 20°C to 40°C at an operating speed of 3500r / min can be represented by a straight line, wherein t1 is less than t2, less than t3, and less than t4. It can be seen that the higher the operating speed of the washing device, the shorter the time required for the water temperature to rise from the first temperature to the second temperature, and it can also be seen that the higher the temperature, the slower the temperature rise rate. This is just an example.

[0053] In an embodiment of the present invention, all temperatures between the first temperature and the second temperature can be divided into a preset number of temperature intervals, wherein the number of temperature intervals is not limited and can be set according to factors such as the accuracy requirements of the detection results or the calculation cost. In a specific embodiment, 20°C to 40°C can be divided into 4 intervals, namely 20°C to 25°C, 25°C to 30°C, 30°C to 35°C and 35°C to 40°C, as an example only. The washing device can be controlled to operate at different operating speeds in different temperature ranges, and the time required for temperature rise in each temperature range can be recorded. There is no limit on the setting of the operating speed. For example, after the water temperature is heated to the first temperature, the operating speed of the washing device can be increased to 2000r / min, and the time temp1 taken for the water temperature to heat from 20°C to 25°C can be recorded; the washing pump speed can be increased to 2500r / min, and the time temp2 taken for the water temperature to heat from 25°C to 30°C can be recorded; the washing pump speed can be increased to 3000r / min, and the time temp3 taken for the water temperature to heat from 30°C to 35°C can be recorded; the washing pump speed can be increased to 3500r / min, and the time temp4 taken for the water temperature to heat from 35°C to 40°C can be recorded. This is just an example.

[0054] In an embodiment of the present invention, the time required for temperature rise recorded in all temperature intervals can be summed to obtain the current required heating time when the water temperature is heated from the first temperature to the second temperature, that is, time1+time2+time3+time4=T, where T represents the current required heating time, which is only used as an example.

[0055] The present invention divides the water temperature into multiple temperature intervals, controls the washing device to operate at different operating speeds in different temperature intervals, and obtains the accumulated temperature rise time of multiple temperature intervals as the heating time required when the current temperature is heated to the second temperature. That is, multi-stage cumulative judgment can reduce interference factors and reduce the control resources of the washing device's operating speed.

[0056] Step S203: determining the current scale level of the equipment based on the current required heating time.

[0057] Specifically, the above step S203 includes:

[0058] Step S2031: Obtain the required time for the standard temperature rise corresponding to each temperature interval.

[0059] The time required for the standard temperature rise is the heating time corresponding to controlling the washing device to heat from the first temperature to the second temperature at the operating speed corresponding to the current temperature range when the equipment is in a scale-free state.

[0060] Step S2032 : determining a plurality of preset temperature rise time intervals based on the standard temperature rise time intervals corresponding to each temperature interval.

[0061] Among them, different time ranges required for different temperature rises correspond to different device scale levels, and the duration values of the time ranges required for temperature rises are positively correlated with the device scale levels.

[0062] Step S2033: Determine the current device scale level based on the time range required for temperature rise corresponding to the currently required heating duration.

[0063] Such as Figure 3 , in the embodiment of the present invention, the heating durations corresponding to heating from the first temperature to the second temperature at different operating speeds are obtained as the standard time required for temperature rise corresponding to the temperature range where the operating speed is located. And multiple preset time ranges required for temperature rise can be determined based on the standard time required for temperature rise corresponding to each temperature range, such as 0 - t1, t1 - t2, t2 - t3, t4 - tmax, where tmax represents the highest temperature value to which the water temperature can be heated, only for example. Different device scale levels correspond to different time ranges required for temperature rise. If T < t1, it means the device has no scale. When t1 < T < t2, it means the scale level is low - grade scale. When t2 < T < t3, it means the device scale level is medium - grade scale. When t3 < T < t4, it means the scale level is relatively high - grade scale. When T > t4, it means the device scale level is high - grade scale, only for example.

[0064] In the embodiment of the present invention, it can be judged the time range required for temperature rise where the currently required heating duration T is located when the calculated water temperature is heated from the first temperature to the second temperature, and then the current device scale level can be determined, only for example.

[0065] The present invention studies the time required to heat to the target temperature at different speeds. By comparing the cumulative time with the time required to heat to the target temperature corresponding to different speeds, the judgment of the scale degree is improved, and then the scale cleaning operation can be accurately carried out accordingly, realizing a flexible scale removal function.

[0066] Step S204: Perform corresponding scale cleaning operations based on the current device scale level.

[0067] Specifically, the above - mentioned step S204 includes:

[0068] Step S2041: Determine the dosage of the scale remover, the device washing time, the water heating temperature, and the washing pump speed based on the current device scale level.

[0069] Step S2042: Perform scale cleaning operations on the device based on the dosage of the scale remover, the device washing time, the water heating temperature, and the washing pump speed.

[0070] The embodiment of the present invention can set different scale levels to perform corresponding descaling operations. The specific operation for performing the corresponding descaling is not limited and can be set according to the equipment model and user. The more scale adhesion, the more descaling agent is added, and the temperature and time are longer. For example, when the equipment is scale-free, no descaling agent is added, and the equipment washing time is set to 30 minutes and the heating temperature is 70°C; when the equipment scale level is low, 10g of descaling agent is added, the washing time is set to 30 minutes, and the heating temperature is 70°C; when When the scale level of the equipment is medium, set the addition of 15g of descaling agent, the washing time is 35 minutes, and the heating temperature is 70°C; when the scale level of the equipment is relatively high, set the addition of 20g of descaling agent, the washing time is 40 minutes, and the heating temperature is 75°C; when the scale level of the equipment is high, set the addition of 25g of descaling agent, the washing time is 45 minutes, and the heating temperature is 75°C. This is just an example, and the operating speed of the washing pump during equipment cleaning can also be set based on the scale level of the equipment, without limitation.

[0071] After determining the current scale level of the equipment, the embodiment of the present invention can determine the amount of descaling agent added, the equipment washing time and the water heating temperature corresponding to the current scale level of the equipment based on the pre-set different scale levels and different degrees of scale cleaning operation requirements, and then perform the scale cleaning operation on the equipment based on the amount of descaling agent added, the equipment washing time and the water heating temperature.

[0072] The present invention sets different degrees of scale cleaning operations corresponding to different scale levels, which not only realizes the descaling function, but also can flexibly automatically perform the corresponding degree of scale cleaning operations based on the scale level to ensure the washing effect of the equipment.

[0073] In this embodiment, a device scale cleaning method is provided, which can be used in the above-mentioned controller. Figure 4 Flowchart of a method for cleaning scale of equipment according to an embodiment of the present invention. Figure 4 As shown, the process includes the following steps:

[0074] Step S401: In response to the device entering the cleaning mode, the device is controlled to perform a water intake operation, and after the device completes the water intake, the water temperature is heated. Figure 2 Step S201 of the illustrated embodiment will not be described in detail here.

[0075] Step S402: Control the operation of the washing device and record the current heating time required when the water temperature is heated from the first temperature to the second temperature. The operating speed of the washing device is positively correlated with the water temperature. Figure 2 Step S202 of the illustrated embodiment will not be described in detail here.

[0076] Step S403: Determine the current equipment scale level based on the current required heating time. Figure 2 Step S203 of the illustrated embodiment will not be described in detail here.

[0077] Step S404: Execute the corresponding scale cleaning operation based on the current scale level of the equipment. Figure 2 Step S204 of the illustrated embodiment will not be described in detail here.

[0078] Step S405 , determining whether there is special water softening salt in the water softener of the device; if there is no special water softening salt in the water softener, prompting the user to add special water softening salt to the water softener.

[0079] The embodiment of the present invention can determine whether there is a salt concentration float in the water softener of the device after performing the corresponding scale cleaning operation on the current device. When the salt concentration is detected to be as low as zero, the salt concentration float is detected to be empty, and it is determined that there is no special salt for softening water in the water softener of the device. The user can be prompted with information that the water softener is short of salt. The information prompting salt shortage is not limited. The salt shortage reminder can be notified through the display panel of the device, and the salt shortage reminder can also be sent to a mobile terminal connected to the device. As an example only, after the user responds to the salt shortage reminder, the special salt for softening water can be added to the water softener.

[0080] Step S406: If the current scale level of the device is greater than the preset scale level threshold, adjust the currently set water hardness level of the device.

[0081] The water hardness level in the embodiment of the present invention is divided into levels 0-7. Level 7 indicates high local water hardness, a smaller amount of water that can be softened at one time by the water softener, and a higher reduction frequency and salt usage. For example, a user can set a water hardness level, such as level 3. For example, after determining that the water softener contains special softening salt, a comparison can be made to determine whether the current device scale level is greater than a preset scale level threshold. The setting of the preset scale level threshold is not limited, and the level threshold can be set to a low scale threshold. For example, if it is determined that the current device scale level is greater than the preset scale level threshold, it indicates that the water hardness level has been adjusted too low. Because the softener has a certain softening capacity and can soften both water hardness and device scale, if it is determined that the water hardness level has been adjusted too low, the water hardness level can be adjusted to a higher level. For example, if the user sets the water hardness level to level 3, more of the softening capacity of the softener is used to soften device scale. If the calculated result is medium scale, it indicates that the water hardness level is too low and needs to be adjusted to level 4. For example,

[0082] The present invention reminds users to increase the water hardness level parameter based on the scale level of the equipment, which can ensure the washing effect of the equipment and the washing performance of each component, and also enables users to understand the corresponding parameter settings of scale, thereby improving user experience.

[0083] In a specific embodiment, Figure 5 As shown, after the dishwasher runs in self-cleaning mode, it enters the pre-wash stage, and the device is controlled to perform the water inlet operation. After the dishwasher completes the water inlet, the water temperature is heated to 20°C and the washing pump speed is increased to 2000r / min. The temperature range from 20°C to 40°C is divided into 4 temperature intervals, that is, each temperature interval has a temperature rise of 5°C, and the operating speed of the washing pump in each temperature interval is increased by 500r / min accordingly. The time required for the temperature rise in each temperature interval is recorded. When the temperature reaches 40°C and the operating speed of the washing pump reaches 3500r / min, the time required for the temperature rise in each temperature interval is summed to obtain the cumulative time T. T is compared with the time interval composed of t1, t2, t3, and t4 to determine the scale level of the current device. In the main wash stage, the corresponding descaling dosage is added based on the scale level of the current device to wash the device, and the water hardness level parameter adjustment in the subsequent stage is completed. For detailed description, please refer to the above embodiment and will not be repeated here.

[0084] This embodiment also provides an equipment scale cleaning device, which is used to implement the above-mentioned embodiments and preferred embodiments. Details already described will not be repeated here. As used below, the term "module" may refer to a combination of software and / or hardware that implements a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementation using hardware, or a combination of software and hardware, is also possible and contemplated.

[0085] This embodiment provides a device for cleaning scale of equipment, such as Figure 6 As shown, the device includes a washing device, including: a water temperature heating module 601, which is used to control the device to perform a water intake operation in response to the device entering a cleaning mode, and to heat the water temperature after the device completes the water intake.

[0086] The heating time recording module 602 is used to control the operation of the washing device and record the current heating time required when the water temperature is heated from the first temperature to the second temperature. The operating speed of the washing device is positively correlated with the water temperature.
