Problems solved by technology

[0004] However, because the liquid storage box is in a humid and closed environment for a long time, a large number of bacteria will grow in the liquid storage box, and will enter the washing water during the feeding process, causing pollution to the clothes
Or the gradual increase of bacteria will cause the liquid storage box to produce peculiar smell, which will affect the user's comfort

Embodiment 1

[0039] In this embodiment, the sterilizing device adopts an ultraviolet sterilizing lamp to kill bacteria growing in the detergent box through ultraviolet irradiation. In this embodiment, the ultraviolet germicidal lamp is set as a short-wave germicidal ultraviolet light, which has weak penetrating ability and cannot penetrate the plastic material used to make the detergent box, so it will not cause harm to users and ensure the safety of the washing machine.

[0040] In this embodiment, since the interior space of the detergent box is small, direct irradiation at 254 nm can completely cover the interior space, avoiding the air pollution caused by ozone diffusion caused by the strong sterilizing effect of too short ultraviolet rays and the aging of washing machine components.

[0041] In this embodiment, the ultraviolet germicidal lamp adopts a smaller LED lamp, and at least one ultraviolet germicidal lamp is set on the top of the detergent box or at a higher position on the sid...

Embodiment 2

[0050] Such as figure 2 As shown, in the present embodiment, the detergent box is provided with a judging unit for judging the liquid level of the detergent, and

[0051] Before step 1), or between step 1) and step 2), or between step 2) and step 3), step A) is added to detect the liquid level of detergent in the detergent box. By detecting the liquid level of detergent in the detergent box, the specific situation in the detergent box can be understood, and the efficiency of sterilization can be further improved and the effect of sterilization can be ensured.

[0052] The judging unit of the washing machine in this embodiment can detect the liquid level of the detergent by installing a detection device on the detergent box, and then calculate the sterilization time of the detergent box sterilization device of the washing machine through the main controller. The detection device may be composed of a liquid level sensor or a detection device.

[0053] The judging unit of the ...

Embodiment 3

[0056] In this embodiment, because the detergent in the detergent box is less, the area of ​​the detergent box exposed to air is more, and the inner surface of the detergent box will be more likely to breed bacteria.

[0057] Therefore, in step 3) of the washing machine detergent box sterilization control method in this embodiment, the sterilization time is mainly determined according to the liquid level of detergent in the detergent box.

[0058] In this embodiment, when the liquid level of the detergent in the detergent box is detected as L, the sterilizing working time is calculated as T. The size of the area of ​​the washing box in contact with the air can be judged by the liquid level of the detergent, so as to determine the sterilization time.

[0059] Preferably, when the liquid level L is getting smaller and smaller, the sterilization time T is getting longer. Adopting the method in this embodiment can ensure that the detergent box is fully sterilized. Since the deterge...

Abstract

The invention relates to a method for sterilization control over a detergent box of a washing machine and the washing machine. The washing machine comprises a judging unit for judging the liquid level height of a detergent and at least one sterilization device. The sterilization device is arranged in the detergent box. The method for sterilization control over the detergent box of the washing machine comprises a step 1) of causing the washing machine to receive detergent placing signals; a step 2) of starting the sterilization device; a step 3) of determining sterilization time; a step 4) of executing operation to the sterilization time and then ending sterilization; and a step 5) of placing the detergent in a washing machine washing bucket. According to the washing machine, through the sterilization device, the detergent box can be prevented from breeding bacteria and generating abnormal smells and secondary pollution to clothes washing is avoided, and the washing machine is remarkable in sterilization effect, simple in structure and suitable for production and popularization.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a washing machine detergent box sterilization control method and a washing machine. Background technique [0002] At present, the detergent automatic feeding function has been more and more widely used in washing machines. The user only needs to put the clothes into the washing bucket, and the washing machine can automatically complete the clothes volume detection, and complete the detergent dosage judgment and adding process accordingly, and then complete the whole process. Laundry process. The step of manually adding detergent is omitted, making the washing machine more intelligent. The existing detergent automatic feeding device is provided with one or more detergent boxes, which store a large amount of detergent in advance, and automatically put it into the washing machine through program control when the user washes. [0003] For example, Patent No. 201420354703.X discloses...
