Laundry treatment apparatus control method and laundry treatment apparatus Technical Field The present invention relates to the field of laundry treatment technology, and in particular, to a laundry treatment apparatus control method and a laundry treatment apparatus. Background Laundry treatment apparatuses such as clothes dryers, washing machines with a clothes drying function, laundry care machines, and the like are capable of drying and heating laundry. Taking a heat pump type clothes treatment device as an example, the heat pump type clothes treatment device comprises a drying air duct and a clothes treatment cavity, wherein an air outlet of the drying air duct is connected with an air inlet of the clothes treatment cavity, and an air outlet of the clothes treatment cavity is connected with the air inlet of the drying air duct. The drying air duct is internally provided with a drying fan, a compressor, an evaporator, a condenser and a throttling device, the compressor, the evaporator, the condenser and the throttling device are connected to form a circulation loop of refrigerant so as to heat air flow in the drying air duct, when the drying fan operates, the heated air flow is conveyed to the clothes treatment cavity, moisture in internal clothes is taken away and returned to the drying air duct again, and drying of the clothes is realized in such a circulation manner. In the existing heat pump type clothes treatment equipment, if the hot and humid air only depends on a heat pump system, the temperature of the hot and humid air is slowly increased in a lower temperature environment. The condensing system formed by the evaporator and the condenser condenses most of moisture in the air flow flowing out of the clothes treatment cavity from a gaseous state into liquid, so that the moisture content in the air flow after flowing through the condenser is reduced. When the temperature difference between the condenser and the evaporator in the drying air duct is smaller, the condensation effect is poorer, the drying efficiency is lower, the clothes cannot be dried at any time by the clothes treatment equipment with high efficiency, the drying time is prolonged or the clothes are difficult to be dried after the preset drying time is reached, and the use experience is poorer. Accordingly, there is a need for a laundry treating apparatus control method and laundry treating apparatus to solve the above-mentioned problems in the prior art. Disclosure of Invention The invention aims to provide a control method of clothes treatment equipment and the clothes treatment equipment, which can ensure that the clothes treatment equipment can always dry clothes with high efficiency in the whole drying process, ensure that the clothes can be dried to the degree required by users, and improve the experience of use.
