Detailed Description
In order to better understand the purpose, structure and function of the present invention, a dishwasher and a water shortage control method thereof according to the present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the water shortage control method of the dishwasher of the present invention, in which the dishwasher includes a tub, a water adding device for injecting water into the tub, a spraying device, a heating device for heating water in the tub, and a temperature sensor for detecting a temperature of water in the tub, includes:
water injection: injecting a certain amount of water into a water tank of the dish washing machine;
water shortage detection: when the dishwasher is detected to enter a washing stage, a washing pump is started, water in a water tank is heated within a set time, the temperature value of the water in the water tank before and after heating is obtained, and a temperature difference value is calculated;
water shortage judging step: if the temperature difference value of the water in the water tank before and after heating is greater than or equal to a preset temperature threshold value, the water tank is in a water shortage state; and if the temperature difference value of the water in the water tank before and after heating is smaller than a preset temperature threshold value, the water in the water tank is abundant, and the heating device is started to enter a washing mode.
According to the formula of specific heat capacity: q ═ P ═ T ═ C ═ m ^ Δ T
Wherein Q is the heat absorption capacity of the water in the water tank, P is the heating power, T is the heating time, C is the specific heat capacity of the water and is a constant, m is the mass of the water in the water tank, and Delta T is the temperature difference of the water in the water tank before and after heating after the heating time T. From the formula, it can be seen that if the water level in the water tank is operating at the working water level, the quality of the water in the water tank needs to be above a threshold, and when the heating device heats the water in the water tank, the corresponding temperature difference is within a certain range. Meanwhile, the volume and the shape in the water tank are constant values, and water with certain mass has a specific height after being injected into the water tank. Therefore, the liquid level in the water tank can be obtained by heating the water in the water tank and determining the temperature variation, and whether the water tank is in a water shortage state or not is judged.

In the water replenishing step, after water is replenished for multiple times, when the total water replenishing amount is larger than or equal to the preset water replenishing amount, or the total water replenishing time is larger than or equal to the preset water replenishing time, or the water replenishing times are larger than or equal to the preset water replenishing times, the washing pump 6 is stopped, and an alarm is prompted.
In the water replenishing step, the amount of water injected into the water tank once is between 0.5 and 0.8L.
In the water shortage detection step, if the temperature difference value of the water in the water tank before and after heating is smaller than a preset abnormal temperature threshold value, an abnormal condition is prompted and an alarm is given, generally, the temperature difference value in the water tank is too small, and the situation that water overflows due to the fact that too much water is initially added in the water tank or the situation that heating cannot be conducted due to the fault of a heating device can occur. The preset abnormal temperature threshold value can be between 0.3 and 0.5 ℃. If the heating device runs normally, the water temperature change of the water injected into the water tank within a certain time cannot be too small after the water is heated by the heating device; otherwise, if the heating device fails, the temperature of the water in the water tank does not change greatly or does not change within a certain time.
