[0056] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0057] Example 1

[0058] To reduce the manufacturing cost of dishwashers and the complexity of their electrical systems, and to more accurately adjust the washing modes of dishwashers, embodiments of the present invention provide a dishwasher control method. Figure 1 A flowchart of a dishwasher control method provided in Embodiment 1 of the invention; the dishwasher control method includes the following steps:

[0059] Step 101: Obtain the influent water quality, influent water specific heat capacity, and oil specific heat capacity.

[0060] The inlet water quality is determined by the inlet water flow rate and the inlet water time. The inlet water quality before the start of the pre-wash mode is calculated using the formula m1 = L * Δt1, where m1 is the inlet water quality, L is the inlet water flow rate (detected by a water flow sensor), and Δt1 is the inlet water time. The specific heat capacity of grease is the specific heat capacity of residual grease on household dishes. Preferably, the specific heat capacity of grease is 2.1 J / (kg·℃). This value is obtained from experimental data on the specific heat capacity of residual grease on typical household dishes. The experimental data is as follows: Figure 2 As shown in the figure. Where J is the unit joule, kg is the unit kilogram, and ℃ is the unit degree Celsius.

[0061] Step 102: Obtain the specific heat capacity of the wastewater during the cleaning process.

[0062] Wastewater is a mixture of oil that has been washed away by the incoming water and the incoming water.

[0063] Step 103: Adjust the cleaning mode of the dishwasher according to the specific heat capacity of the inlet water, the specific heat capacity of the wastewater, the specific heat capacity of the oil, and the mass of the inlet water.

[0064] The mass of oil stains can be calculated using the formula: C3 = (m1*C1 + m2*C2) / (m1 + m2). Based on the mass of oil stains in the wastewater and the mass of the influent water, the turbidity of the wastewater can be obtained, and the dishwasher's cleaning mode can be adjusted accordingly. Where m1 is the mass of the influent water, m2 is the mass of the oil stains, C1 is the specific heat capacity of the influent water, C2 is the specific heat capacity of the oil stains, and C3 is the specific heat capacity of the wastewater.

[0065] In this embodiment, the dishwasher's cleaning mode is adjusted based on the specific heat capacity of the inlet water, the specific heat capacity of the wastewater, the inlet water mass, and the specific heat capacity of the oil. This allows for intelligent adjustment of the dishwasher's cleaning mode without the need for an additional turbidity sensor. Furthermore, this control method detects wastewater throughout the entire dishwasher cavity, resulting in more accurate detection and thus more precise adjustment of the dishwasher's cleaning mode.

[0066] In one embodiment, obtaining the influent water quality, influent water specific heat capacity, and oil specific heat capacity includes:

[0067] S1: Obtain the inlet water temperature;

[0068] S2: Raise the inlet water temperature to the first preset temperature, and record the first heating time, the first heating power, and the first temperature rise.

[0069] S3: Calculate the first specific heat capacity of the inlet water based on the inlet water mass, the first heating time, the first temperature rise, and the first heating power.

[0070] The specific heat capacity of the inlet water can be calculated using the formulas Q1 = P1 * Δt2 and C1 = Q1 / m1 * ΔT1. Here, Q1 represents the heat released by the dishwasher during the process of raising the inlet water temperature to the first preset temperature, P1 is the first heating power, Δt2 is the first heating time, m1 is the mass of the inlet water, ΔT1 is the first temperature rise, and C1 is the specific heat capacity of the inlet water.

[0071] In this embodiment, since the water quality of different users' household water may vary, the specific heat capacity of standard water is not used to avoid inaccurate data calculations due to water quality differences, which in turn would lead to inaccurate adjustments to the dishwasher's cleaning mode in the subsequent process. Furthermore, raising the inlet water temperature to a first preset temperature for pre-treating the items to be washed makes it easier to remove oil stains, ensuring more accurate subsequent calculations.

[0072] In one embodiment, obtaining the wastewater mass and the second specific heat capacity of the wastewater after the pre-washing mode ends includes:

[0073] S1: Obtain wastewater temperature;

[0074] S2: Raise the wastewater temperature to the second preset temperature, and record the second heating time, the second temperature rise, and the second heating power;

[0075] S3: The specific heat capacity of the wastewater is calculated based on the influent quality, the second heating time, the second heating power, the second temperature rise, the specific heat capacity of the oil, and the specific heat capacity of the influent.

[0076] The specific heat capacity of wastewater can be calculated using the formulas Q2=P2*Δt3, C3=Q2 / (m1+m2)*ΔT2 and C3=(m1*C1+m2*C2) / (m1+m2). Here, Q2 is the heat released by the dishwasher during the process of raising the wastewater temperature to the second preset temperature, P2 is the second heating power, Δt3 is the second heating time, m1 is the mass of the incoming water, m2 is the mass of the oil (although used in the formula, it can be eliminated during the calculation, so the specific heat capacity of wastewater can still be obtained even without knowing the mass of the oil), ΔT2 is the second temperature rise, and C3 is the specific heat capacity of the wastewater.

[0077] In this embodiment, the specific heat capacity of the wastewater can be calculated more accurately based on the inlet water quality, the second heating time, the second heating power, the second temperature rise, the specific heat capacity of the oil, and the specific heat capacity of the inlet water, thereby making the subsequent adjustment of the dishwasher's cleaning mode more accurate.

[0078] In one embodiment, adjusting the dishwasher's cleaning mode includes:

[0079] S1: The mass of oil contamination is calculated based on the specific heat capacity of the influent, the specific heat capacity of the oil contamination, the specific heat capacity of the wastewater, as well as the mass of the influent and the mass of the wastewater.

[0080] S2: Adjust the dishwasher's cleaning mode based on the mass ratio of oil stains to inlet water.

[0081] In this embodiment, adjusting the dishwasher's cleaning mode based on the mass ratio of oil stains to incoming water ensures a more effective cleaning process. This avoids the drawbacks of using an overly powerful cleaning mode when the oil stains are low, wasting water and energy, or using an overly gentle cleaning mode when the oil stains are high, resulting in poor cleaning and requiring multiple washes. This not only improves the user experience of the dishwasher but also saves energy and water resources.

[0082] In one embodiment, adjusting the dishwasher's cleaning mode based on the mass ratio of oil stains to influent water includes:

[0083] When the mass ratio is less than or equal to the first threshold, the system is switched to the first cleaning mode.

[0084] When the quality ratio is greater than the first threshold and less than or equal to the second threshold, the system is switched to the second cleaning mode.

[0085] When the mass ratio is greater than the second threshold, the system will switch to the third cleaning mode.

[0086] Among them, the first cleaning mode has a lower cleaning capacity than the second cleaning mode; the second cleaning mode has a lower cleaning capacity than the third cleaning mode; and the first threshold is lower than the second threshold.

[0087] In the first cleaning mode, the cleaning temperature, cleaning time, and water replenishment amount are all set to the first preset cleaning temperature, cleaning time, and water replenishment amount. In the second cleaning mode, the cleaning temperature, cleaning time, and water replenishment amount are all set to the second preset cleaning temperature, cleaning time, and water replenishment amount. In the third cleaning mode, the cleaning temperature, cleaning time, and water replenishment amount are all set to the third preset cleaning temperature, cleaning time, and water replenishment amount. The first, second, and third preset cleaning temperatures, cleaning times, and water replenishment amounts can be set according to specific circumstances.

[0088] In this embodiment, the dishwasher's cleaning modes are divided into a first cleaning mode, a second cleaning mode, and a third cleaning mode based on a first threshold and a second threshold. A cleaning mode matching the mass ratio is selected based on the relationship between the mass ratio and the first and second thresholds. This ensures that the dishwasher provides optimal cleaning results for items with varying degrees of oiliness. The first threshold being lower than the second threshold can be set according to specific circumstances.

[0089] In one embodiment, the quality of the incoming water is determined by the items to be washed.

[0090] The water intake quality of a dishwasher will differ when the items to be washed vary in at least one of the following: volume, quantity, or type. For example, consider a dishwasher pre-washing one bowl and ten bowls with the same level of grease. Logically, the cleaning mode for one bowl and ten bowls should be the same if the grease levels are similar. However, if the same water intake quality is used, the mass of grease removed from the ten bowls after pre-washing might be ten times that of the one bowl. Therefore, the ratio of grease mass to water mass for the ten bowls will be ten times that for the one bowl. Consequently, the cleaning mode for one bowl and ten bowls with the same level of grease may differ. Therefore, the water intake quality should take into account the quantity of items to be washed. Similarly, the volume and type of items to be washed must also be considered. The type of items to be washed includes at least one of ceramic, plastic, glass, and metal.

[0091] In this embodiment, the quality of the incoming water is determined by the items to be washed, which allows for a more accurate adjustment of the dishwasher's cleaning mode based on the mass ratio of oil stains to incoming water.

[0092] In one embodiment, combined Figure 3 A flowchart for calculating the amount of oil stains in a dishwasher is provided for further explanation.

[0093] S1: Dishwasher water intake. The water quality is calculated based on the water flow rate and intake time.

[0094] The influent mass is calculated using the formula m1=L*Δt1, where m1 is the influent mass, L is the influent flow rate, and Δt1 is the influent time.

[0095] S2: Detect the current temperature, turn on the heating device, and heat the dishwasher for cleaning. Stop heating when the set temperature is reached.

[0096] The heating element includes, but is not limited to, a heating plate. Heating the dishwasher during cleaning makes it easier for grease to be removed from dishes, allowing for more accurate calculations of grease levels.

[0097] S3: Calculate the specific heat capacity of the incoming water in the user's home based on the first heating power, first heating time, first heating amount, and incoming water mass of the heating plate.

[0098] The specific heat capacity of the incoming water in the user's home can be calculated using the formulas Q1 = P1 * Δt2 and C1 = Q1 / m1 * ΔT1. Here, Q1 represents the heat released by the dishwasher in this step, P1 is the first heating power, Δt2 is the first heating time, T1 is the first heating amount, m1 is the mass of the incoming water, and C1 is the specific heat capacity of the incoming water.

[0099] S4: Detect the current temperature, heat the wastewater from the dishes that have been washed, and stop heating when the set temperature is reached.

[0100] S5: Calculate the specific heat capacity of the wastewater based on the second heating power of the heating plate, the second heating time, the second heating amount, the specific heat capacity of the oil, the specific heat capacity of the inlet water, and the mass of the inlet water.

[0101] The specific heat capacity of wastewater can be calculated using the formulas Q2=P2*Δt3, C3=Q2 / (m1+m2)*ΔT2 and C3=(m1*C1+m2*C2) / (m1+m2). Here, Q2 is the heat released by the dishwasher during the process of raising the wastewater temperature to the second preset temperature, P2 is the second heating power, Δt3 is the second heating time, m1 is the mass of the influent water, m2 is the mass of the oil (although used in the formula, it can be eliminated during the calculation, so the specific heat capacity of wastewater can still be obtained even without knowing the mass of the oil), ΔT2 is the second temperature rise, and C3 is the specific heat capacity of the wastewater.

[0102] S6: Calculate the oil pollution mass based on the specific heat capacity of the influent, the mass of the influent, the specific heat capacity of the wastewater, and the mass of the wastewater.

[0103] According to the formula: C3=(m1*C1+m2*C2) / (m1+m2), the mass of oil contamination can be calculated, where m1 is the mass of influent, m2 is the mass of oil contamination, C3 is the specific heat capacity of wastewater, C1 is the specific heat capacity of influent, and C2 is the specific heat capacity of oil contamination. In one embodiment, combined with Figure 4 To further explain the heating process of the dishwasher.

[0104] S1: Open the inlet valve to achieve the target water intake volume.

[0105] S2: Detect the current inlet water temperature and turn on the heating device.

[0106] S3: Detect the current inlet water temperature and turn on the heating device.

[0107] S4: Check if the inlet water temperature has reached the first set temperature. If not, continue heating and repeat S4; if yes, proceed to S5.

[0108] S5: Turn off the heating device and calculate the specific heat capacity of the inlet water.

[0109] S6: Detect the current sewage temperature and turn on the heating device.

[0110] S7: Detect whether the wastewater temperature has reached the second set temperature. If not, continue heating and repeat S7; if yes, proceed to S8.

[0111] S8: Turn off the heating device and calculate the specific heat capacity of the sewage.
