Problems solved by technology

Existing washing machines only rely on temperature sensors to detect the temperature of the water entering the washing machine. Since the boiling point is different in different regions, if the heating target temperature is set too high in high-altitude areas, making the boiling point lower than the target temperature, the water in the washing machine will The water will be heated all the time because it cannot reach the set target temperature, and it is prone to dry boiling; if the set heating target temperature is too low, making the boiling point higher than the target temperature, then the water in the washing machine will not reach the boiling point, and thus cannot be heated. Optimum disinfection effect on clothes

Embodiment approach 1

[0027] The washing machine sterilizes the clothes by heating the water in the washing machine. Usually, the temperature of the water detected by the temperature sensor has different boiling points in different regions. If the boiling point is lower than the target temperature, the water in the washing machine will be heated all the time because it cannot reach the set target temperature, and it is prone to dry burning; if the set heating target temperature is too low, making the boiling point higher than the target temperature, then the washing machine The water inside will not be able to reach the boiling point, thus making it impossible to achieve the best sterilization effect on the clothes. In view of the above problems, this embodiment provides a method for calibrating the boiling point of a washing machine, such as figure 1 shown, including the following steps:

[0028] S11. The washing machine is heated after entering the water to a preset water level.

[0029] S12. W...

Embodiment approach 2

[0034] This embodiment is a further improvement made on the basis of Embodiment 1, such as figure 2 shown, including the following steps:

[0035] S21. The washing machine is heated after entering the water to a preset water level.

[0036] Open the water inlet valve of the washing machine, and the washing machine starts to take in water. In this embodiment, the water inlet valve can be a solenoid valve, and the control device of the washing machine controls the opening and closing of the solenoid valve.

[0037] Before opening the above-mentioned water inlet valve, a preset water level needs to be set first, and the preset water level can be the common washing water level set by the washing machine, or the water inlet water level set according to the needs of the user.

[0038] After water intake, the actual water intake level is detected, and when the water intake level is the same as the preset water level, the water intake valve is closed to stop water intake.

[0039] ...

Embodiment approach 3

[0059] This embodiment also provides a washing machine, which uses the method for calibrating the boiling point of the washing machine in Embodiment 1 or Embodiment 2 to calibrate the boiling point, so as to avoid damage to the washing machine due to the fact that the washing machine cannot reach the boiling point in high-altitude areas due to continuous heating. The washing machine can be a pulsator washing machine or a drum washing machine.

[0060] The washing machine is provided with a heating device for heating the water inlet of the washing machine. The washing machine is also provided with a temperature sensor for detecting the temperature of the incoming water. The specific structures and positions of the heating device and the temperature sensor belong to the prior art, and are not specifically limited here.

[0061] Regardless of whether the washing machine is in the washing process or the rinsing process, as long as the heating process is involved, the heating targ...

Abstract

The invention relates to the technical field of washing machines, and discloses a washing machine boiling point calibration method, a washing machine and a control method of the washing machine. The washing machine boiling point calibration method comprises the following steps: S1, performing heating after water entering the washing machine reaches a preset water level; S2, when the water temperature reaches a preset temperature, continuously performing heating and detecting the temperature of the water, and when the water temperature is not changed within a first preset time period, storing the temperature; and S3, obtaining the boiling point temperature of the washing machine according to the stored temperature in the step S2, and storing the boiling point temperature as a target temperature for heating of the washing machine. When the washing machine carries out a heating program, the boiling point temperature is called as the target temperature of heating, the boiling point can bereached, and sterilization and disinfection are carried out on clothes; and the phenomenon of dry burning of the washing machine can be prevented. According to the washing machine and the control method thereof disclosed by the invention, the boiling point is calibrated by adopting the washing machine boiling point calibration method, and the phenomenon that the washing machine cannot reach the boiling point and is damaged is avoided.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a method for calibrating the boiling point of a washing machine, a washing machine and a control method for the washing machine. Background technique [0002] At present, as consumers have more and more requirements for laundry sterilization and disinfection, washing machines with heating and ironing have also become a trend. Existing washing machines only rely on temperature sensors to detect the temperature of the water entering the washing machine. Since the boiling point is different in different regions, if the heating target temperature is set too high in high-altitude areas, making the boiling point lower than the target temperature, the water in the washing machine will The water will be heated all the time because it cannot reach the set target temperature, and it is prone to dry boiling; if the set heating target temperature is too low, making the boiling point...
