Problems solved by technology

[0004] Under normal circumstances, the water in the washing machine will not overflow to the overflow port, but when too much laundry detergent or washing powder is put into the inner tub, the foam will overflow upwards and often flow out from the overflow port, which will easily corrode the metal parts inside the washing machine or flow into In the line terminal, there is a safety risk

Embodiment 1

[0036] like Figure 1-Figure 5 As shown, this embodiment provides a drum washing machine, the drum washing machine includes a water inlet box 1 and an inner cylinder, the water outlet 5 of the water inlet box 1 is communicated with the inner cylinder, and the upper part of the water outlet 5 of the water inlet box 1 is provided with overflow water Port 2, the overflow port 2 is provided with a foam detection device 3. When the foam in the inner cylinder overflows to the overflow port through the water outlet 5, the foam detection device 3 detects the foam and transmits a signal to the control device of the washing machine, and the washing machine eliminates the overflow port. 2 bubbles.

[0037] The water inlet box 1 is generally installed on the upper part of the drum washing machine, and the detergent box is placed in the water inlet box 1, and next to the water inlet box 1 are electrical components such as circuit boards. When the washing machine enters the water, the exte...

Embodiment 2

[0044] like Figure 3-Figure 5 As shown, this embodiment is a further limitation of Embodiment 1. In this embodiment, the overflow port 2 of the water inlet box 1 is also provided with a foam blowing device 4, and the foam detection device 3 detects the foam and transmits a signal to the washing machine. After the control device, the control device controls the foam blowing device 4 to generate wind to blow and eliminate the foam.

[0045] The foam blowing device 4 of this solution is electrically connected to the control device, and the drum washing machine controls the foam blowing device 4 to work after receiving the signal transmitted by the foam detection device 3 that there is foam at the overflow 2, and generates wind to blow and eliminate the foam. , there is no delay in the process, and the foam can be quickly eliminated to avoid overflowing to the overflow port 2.

[0046] Compared with the method of water intake, direct blowing can have an immediate effect, avoidin...

Embodiment 3

[0060] This embodiment provides a method for controlling a front-loading washing machine according to any one of Embodiments 1 and 2. During the operation of the washing machine, when there is too much foam in the inner tub and overflows upward through the water outlet 5, the washing machine receives the foam When the detection device 3 transmits a signal of foam at the overflow 2, the foam at the overflow 2 is eliminated.

[0061] Specifically, during the operation of the washing machine, when there is too much foam in the inner tub and overflows upward through the water outlet 5, the foam detection device 3 generates a signal after contacting the foam and transmits it to the control device of the washing machine, and the control device controls the foam blowing device 4. Generated wind blows the foam; when the foam detection device 3 no longer contacts the foam, the signal disappears, and the control device controls the foam blowing device 4 to stop rotating.

Abstract

The invention discloses a drum washing machine and a control method. The drum washing machine comprises a water inlet box and an inner cylinder, the water outlet of the water inlet box is communicated with the inner cylinder, the upper part of the water outlet of the water inlet box is provided with a water overflow port, and the overflow port is located at the upper part of the water outlet. A foam detection device is provided. When the foam in the inner cylinder overflows upward to the overflow through the water outlet, the foam detection device detects the foam and transmits a signal to the control device of the washing machine, and the washing machine eliminates the foam at the overflow. In the drum washing machine of the present invention, the foam detection device is provided at the overflow port of the water inlet box, so that the foam at the overflow port can be detected and eliminated in time, the foam can be prevented from overflowing from the overflow port, and the corrosion of parts or flow into the water caused by the overflow of foam can be avoided. Line terminals to avoid potential risks.

Description

technical field [0001] The invention belongs to the field of washing machines, and in particular relates to a drum washing machine and a control method. Background technique [0002] In order to improve the cleaning effect of clothes, washing powder or detergent needs to be put in when washing clothes in the washing machine, and the rich foam can clean clothes more easily. In a general drum washing machine, the water inlet box is arranged on the upper part of the washing tub, and has a feeding port that communicates with the inner tub. The detergent box is placed in the water inlet box. When the washing machine enters the water, the external water can pass the detergent box and the inlet of the water inlet box to bring the detergent into the inner cylinder. In this way, the inner cylinder passes through the injection port and the water inlet box. , The detergent box can communicate with the outside world. [0003] In order to prevent the washing machine from malfunctioning...
