Embodiment 1

[0027] Such as figure 1 As shown, a clothes dryer according to the present invention includes a clothes drying drum 6, a heat pump system and an electric heating system, and the heat pump system includes a compressor 1, a condenser 2, an evaporator 3 and a throttling device 4 , the electric heating system is an electric heating pipe 5, and the clothes dryer also includes a water condenser 7, and the water condenser 7 is arranged between the air outlet of the drying drum 6 and the air inlet of the evaporator. The condenser 2 and the electric heating tube 5 of the heat pump system are heated at the same time to increase the temperature of the gas entering the cylinder, and the water condenser 7 can increase the condensation speed and improve the drying speed. A water valve 8 is arranged on the water condenser 7, and the opening and closing of the water condenser 7 is controlled by the opening and closing of the water valve 8.

[0028] Usually people think that adding the electr...

Embodiment 2

[0031] According to the method for controlling a clothes dryer in the present invention, the clothes dryer includes a clothes drying drum 6, a heat pump system and an electric heating system, the heat pump system includes a compressor 1, a condenser 2, an evaporator 3 and a throttling device 4, The electric heating system is an electric heating tube 5, and the condenser 2 and the electric heating tube 5 cooperate to heat so that the clothes dryer can have the following modes:

[0032] Fast mode: when drying clothes in the fast mode, the electric heating tube 5 is turned on, and the gas entering the drying drum 6 is controlled to be heated by the heat pump system condenser 2 first, then heated by the electric heating tube 5 and then enters the drying drum 6, and the heat pump system is close to the maximum When the load is on, the load of the heat pump system is reduced by means of auxiliary condensation before the heating pipe is disconnected. The auxiliary condensation method ...

Embodiment 3

[0048] Such as figure 2 In this embodiment shown, the clothes dryer includes an auxiliary fan 10, and the way of assisting condensation is to use the auxiliary fan 10 to assist the heat dissipation of the condenser 2 of the heat pump system, reduce the temperature of the condenser, and reduce the load of the heat pump system. Other methods are the same as those in the embodiment Two same.

Abstract

The invention relates to a clothes dryer control method and a clothes dryer. The clothes dryer includes a drying drum, a heat pump system and an electrical heating system; the heat pump system includes a compressor, a condenser, an evaporator and a throttle device; the electrical heating system is an electrical heating tube; the clothes dryer further includes a water condenser and / or an air condenser and / or an assist fan; to control the heat pump system and the electrical heating system to work together, the dryer at least includes a fast mode which is characterized in that: after the compressor is started up and works stably, the electrical heating tube is started up, air which is about to enter the drying drum is controlled to be heated by the heat pump system and the condenser, and then is heated by the electrical heating pipe, and enters the drying drum; and when the heat pump system approaches the maximum load, the load of the heat pump system is reduced through an assist condensation manner, and in this way, it is guaranteed that the electrical heating system and the heat pump system can work at the same time, and the drying speed can be improved.

Description

technical field [0001] The invention relates to the field of clothes dryers, in particular to a clothes dryer control method and the clothes dryer. Background technique [0002] The following gas circulation channel is provided in the existing heat pump type clothes drying device: the heated gas heated by the condenser in the heat pump cycle system is sent into the drying room containing the clothes, and the wet gas that has taken moisture from the clothes is It is sent back to the evaporator for dehumidification, and the dehumidified gas is heated by the condenser again and sent to the drying chamber. [0003] In order to increase the drying speed, some heat pump dryers are equipped with electric heating tubes for auxiliary heating. The combination of electric heating tubes and heat pump systems can shorten the heating time of the dryer, which will indeed shorten the drying time. But the limited scope is only limited to the period from when the compressor just starts dryin...
