When the tap water is used for washing clothes, particularly in the northern winter, the temperature of the tap water is too low, so that the detergent or washing powder which is put in cannot be fully dissolved, the activity of the detergent is poor, and the washing effect is greatly reduced.
In order to solve the above problems, a method generally used in the prior art enables the inlet water of the washing machine to have a proper temperature. As shown in fig. 1, a water inlet box 11 having a water inlet and a water outlet is installed at a water inlet of the washing machine, the water inlet of the water inlet box 11 is communicated with a water inlet pipe 16, and the water outlet of the water inlet box 11 is communicated with a water outlet pipe 17. A metal pipe type heating device is installed in the water inlet box 11, and when the washing machine is used under the condition of low temperature, the heating device can be used for heating the water in the water inlet box 11, so that the temperature of the washing water can be increased.

When water in the water inlet box 11 needs to be heated, an external power supply supplies alternating current to the alternating current electrode 15, when current passes through the heating wire 13, the heating wire 13 generates heat, the heat of the heating wire 13 is used for heating the water in the water inlet box 11, and the purpose of heating water is achieved.
However, the existing metal tube type heating device has problems in use: firstly, the energy efficiency is low, the metal tube type heating device is heated only by heating wires, the output power is less than the input power, the energy conversion rate is less than 1, and the energy conversion rate is low; secondly, the strong electricity is used for electrifying, the power is high during heating, and the use environment of the washing machine is wet, so the safety is relatively poor; thirdly, when the metal tube is used for a long time, scale is easy to be attached, the heating efficiency is seriously hindered, and the heating effect is poor after the metal tube is used for a long time.

Tap water sequentially enters the water containing barrel from the water inlet pipe 26, the water inlet box 21 and the water outlet pipe 27.
Wherein the heating device further comprises at least one semiconductor chilling plate 22. The semiconductor refrigeration piece 22 is connected with a direct current power supply through two electrodes, one end of the semiconductor refrigeration piece is a refrigeration end 222 for refrigeration, the other end of the semiconductor refrigeration piece is a heating end 221 for heating, the semiconductor refrigeration piece 22 is arranged in the wall of the water inlet box 21, the outer side of the semiconductor refrigeration piece is the refrigeration end 222, and the inner side of the semiconductor refrigeration piece is the heating end 221, so that the heating end 221 can be directly contacted with water in the water inlet box 21.
The cooling end 222 and the heating end 221 are made of different semiconductor materials. Specifically, as shown in fig. 3, the cooling end 222 is made of a cooling plate, and the heating end 221 is made of a cooling fin.
