The hot water processing mechanism 10 comprises a first heat exchanger 11 for circulating high-temperature refrigerant and cold water, a second heat exchanger 12 for circulating heat-conducting fluid, and a phase-change material 13, wherein the phase-change material 13 is an energy storage material and can absorb or release a large amount of latent heat by utilizing self phase-change reaction. Specifically, the first heat exchanger 11 has an inlet pipe 111 into which cold water flows and an outlet pipe 112 from which hot water flows. The cold water is changed into hot water after entering the first heat exchanger 11, and the basic heat exchange function of the first heat exchanger 11 is realized. The phase change material 13 is coated outside the first heat exchanger 11 and the second heat exchanger 12, and is used for absorbing heat of a high-temperature refrigerant to realize heat storage of the high-temperature refrigerant when the high-temperature refrigerant flows in the first heat exchanger 11, and simultaneously converting the high-temperature refrigerant after absorbing heat into a low-temperature refrigerant, the phase change material 13 is also used for heating cold water when the cold water flows in the first heat exchanger 11, the phase change material 13 stores a large amount of latent heat, and when the cold water flows in the first heat exchanger 11, the temperature of the cold water is far lower than the temperature of the phase change material 13, and at the moment, the phase change material 13 can release heat to the first heat exchanger 11, so that the cold water in the first heat exchanger 11 is heated and converted into the hot water. Therefore, the hot water can be supplied to the user in a relatively energy-saving way. The phase change material 13 is also used for heating the heat transfer fluid when the second heat exchanger 12 is circulated with the heat transfer fluid, and the first heat exchanger 11 has an inlet (not shown) into which the high temperature refrigerant flows and an outlet (not shown) from which the low temperature refrigerant flows.

By arranging the heating heat exchanger 22 close to the air inlet 231, the heating heat exchanger 22 can heat the outside air as soon as the outside air enters the toilet, so that the outside air can be sufficiently heated as much as possible. And through being close to air outlet 232 setting with cooling heat exchanger 21, outside air is getting into hot water and air treatment module like this, and circulation certain distance rear can reach cooling heat exchanger 21 department, and outside air also can take place the decay of certain degree of energy and the reduction of temperature during this to can realize the cooling to outside air as far as possible.

s4: providing a control module, wherein the control module controls the first heat exchanger 11 to introduce low-temperature refrigerant into the cooling heat exchanger 21 and/or the evaporator 32; the cooling heat exchanger 21 cools air flowing through the cooling heat exchanger 21 by a low-temperature refrigerant

Or, the control module controls the first heat exchanger 11 to introduce the low-temperature refrigerant into the evaporator 32, and controls the second heat exchanger 12 to introduce the heat-conducting fluid into the heating heat exchanger 22;

alternatively, the control module controls the second heat exchanger 12 to introduce the heat transfer fluid into the heating heat exchanger 22 separately.

It is easy to understand that when the hot water air treatment device needs to separately store heat, the control module can control the first heat exchanger 11 to separately introduce the low-temperature refrigerant into the evaporator 32.

When the hot water air treatment device needs to heat and store heat for air at the same time, the control module can control the first heat exchanger 11 to feed low-temperature refrigerant into the evaporator 32 and control the second heat exchanger 12 to feed heat-conducting fluid into the heating heat exchanger 22 at the same time. Similarly, when the hot water air treatment device needs to heat air alone, the control module can control the second heat exchanger 12 alone to heat the heat exchanger 22 and then the heat transfer fluid is introduced into the second heat exchanger.
